Predicting the risk of chemotherapy toxicity in older patients: The Chemotherapy Risk Assessment Scale for High‐Age Patients (CRASH) score

Abstract: BACKGROUND: Tools are lacking to assess the individual risk of severe toxicity from chemotherapy. Such tools would be especially useful for older patients, who vary considerably in terms of health status and functional reserve. METHODS: The authors conducted a prospective, multicentric study of patients aged ≥70 years who were starting chemotherapy. Grade 4 hematologic (H) or grade 3/4 nonhematologic (NH) toxicity according to version 3.0 of the Common Terminology Criteria for Adverse Events was defined as severe. Twenty-four parameters were assessed. Toxicity of the regimen (Chemotox) was adjusted using an index to estimate the average per-patient risk of chemotherapy toxicity (the MAX2 index). In total, 562 patients were accrued, and 518 patients were evaluable and were split randomly (2:1 ratio) into a derivation cohort and a validation cohort. RESULTS: Severe toxicity was observed in 64% of patients. The Chemotherapy Risk Assessment Scale for High-Age Patients (CRASH) score was constructed along 2 subscores: H toxicity and NH toxicity. Predictors of H toxicity were lymphocytes, aspartate aminotransferase level, Instrumental Activities of Daily Living score, lactate dehydrogenase level, diastolic blood pressure, and Chemotox. The best model included the 4 latter predictors (risk categories: low, 7%; medium-low, 23%; medium-high, 54%; and high, 100%, respectively; Ptrend < .001). Predictors of NH toxicity were hemoglobin, creatinine clearance, albumin, self-rated health, Eastern Cooperative Oncology Group performance, Mini-Mental Status score, Mini-Nutritional Assessment score, and Chemotox. The 4 latter predictors provided the best model (risk categories: 33%, 46%, 67%, and 93%, respectively; Ptrend < .001). The combined risk categories were 50%, 58%, 77%, and 79%, respectively; Ptrend < .001). Bootstrap internal validation and independent sample validation demonstrated stable risk categorization and Ptrend < .001. CONCLUSIONS: The CRASH score distinguished several risk levels of severe toxicity. The split score discriminated better than the combined score. To the authors' knowledge, this is the first score systematically integrating both chemotherapy and patient risk for older patients and has a potential for future clinical application.

Clinicopathologic features, patterns of recurrence, and survival among women with triple‐negative breast cancer in the National Comprehensive Cancer Network

Abstract: BACKGROUND: The objective of this study was to describe clinicopathologic features, patterns of recurrence, and survival according to breast cancer subtype with a focus on triple-negative tumors. METHODS: In total, 15,204 women were evaluated who presented to National Comprehensive Cancer Network centers with stage I through III breast cancer between January 2000 and December 2006. Tumors were classified as positive for estrogen receptor (ER) and/or progesterone receptor (PR) (hormone receptor [HR]-positive) and negative for human epidermal growth factor receptor 2 (HER2); positive for HER2 and any ER or PR status (HER2-positive); or negative for ER, PR, and HER2 (triple-negative). RESULTS: Subtype distribution was triple-negative in 17% of women (n = 2569), HER2-positive in 17% of women (n = 2602), and HR-positive/HER2-negative in 66% of women (n = 10,033). The triple-negative subtype was more frequent in African Americans compared with Caucasians (adjusted odds ratio, 1.98; P < .0001). Premenopausal women, but not postmenopausal women, with high body mass index had an increased likelihood of having the triple-negative subtype (P = .02). Women with triple-negative cancers were less likely to present on the basis of an abnormal screening mammogram (29% vs 48%; P < .0001) and were more likely to present with higher tumor classification, but they were less likely to have lymph node involvement. Relative to HR-positive/HER2-negative tumors, triple-negative tumors were associated with a greater risk of brain or lung metastases; and women with triple-negative tumors had worse breast cancer-specific and overall survival, even after adjusting for age, disease stage, race, tumor grade, and receipt of adjuvant chemotherapy (overall survival: adjusted hazard ratio, 2.72; 95% confidence interval, 2.39-3.10; P < .0001). The difference in the risk of death by subtype was most dramatic within the first 2 years after diagnosis (overall survival for 0-2 years: OR, 6.10; 95% confidence interval, 4.81-7.74). CONCLUSIONS: Triple-negative tumors were associated with unique risk factors and worse outcomes compared with HR-positive/HER2-negative tumors. Cancer 2012. © 2012 American Cancer Society.

Annual Report to the Nation on the status of cancer, 1975-2008, featuring cancers associated with excess weight and lack of sufficient physical activity.

Abstract: BACKGROUND: Annual updates on cancer occurrence and trends in the United States are provided through collaboration between the American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR). This year's report highlights the increased cancer risk associated with excess weight (overweight or obesity) and lack of sufficient physical activity (<150 minutes of physical activity per week). METHODS: Data on cancer incidence were obtained from the CDC, NCI, and NAACCR; data on cancer deaths were obtained from the CDC's National Center for Health Statistics. Annual percent changes in incidence and death rates (age-standardized to the 2000 US population) for all cancers combined and for the leading cancers among men and among women were estimated by joinpoint analysis of long-term trends (incidence for 1992-2008 and mortality for 1975-2008) and short-term trends (1999-2008). Information was obtained from national surveys about the proportion of US children, adolescents, and adults who are overweight, obese, insufficiently physically active, or physically inactive. RESULTS: Death rates from all cancers combined decreased from 1999 to 2008, continuing a decline that began in the early 1990s, among men and among women in most racial and ethnic groups. Death rates decreased from 1999 to 2008 for most cancer sites, including the 4 most common cancers (lung, colorectum, breast, and prostate). The incidence of prostate and colorectal cancers also decreased from 1999 to 2008. Lung cancer incidence declined from 1999 to 2008 among men and from 2004 to 2008 among women. Breast cancer incidence decreased from 1999 to 2004 but was stable from 2004 to 2008. Incidence increased for several cancers, including pancreas, kidney, and adenocarcinoma of the esophagus, which are associated with excess weight. CONCLUSIONS: Although improvements are reported in the US cancer burden, excess weight and lack of sufficient physical activity contribute to the increased incidence of many cancers, adversely affect quality of life for cancer survivors, and may worsen prognosis for several cancers. The current report highlights the importance of efforts to promote healthy weight and sufficient physical activity in reducing the cancer burden in the United States.* Cancer 2012;. © 2012 American Cancer Society.

Response of borderline resectable pancreatic cancer to neoadjuvant therapy is not reflected by radiographic indicators

Abstract: BACKGROUND: Experience with preoperative therapy for other cancers has led to an assumption that borderline resectable pancreatic cancers can be converted to resectable cancers with preoperative therapy. In this study, the authors sought to determine the rate at which neoadjuvant therapy is associated with a reduction in the size or stage of borderline resectable tumors. METHODS: Patients who had borderline resectable pancreatic cancer and received neoadjuvant therapy before potentially undergoing surgery at the authors' institution between 2005 and 2010 were identified. The patients' pretreatment and post-treatment pancreatic protocol computed tomography images were rereviewed to determine changes in tumor size or stage using modified Response Evaluation Criteria in Solid Tumors (RECIST) (version 1.1) and standardized anatomic criteria. RESULTS: The authors identified 129 patients who met inclusion criteria. Of the 122 patients who had their disease restaged after receiving preoperative therapy, 84 patients (69%) had stable disease, 15 patients (12%) had a partial response to therapy, and 23 patients (19%) had progressive disease. Although only 1 patient (0.8%) had their disease downstaged to resectable status after receiving neoadjuvant therapy, 85 patients (66%) underwent pancreatectomy. The median overall survival duration for all 129 patients was 22 months (95% confidence interval, 14-30 months). The median overall survival duration for the patients who underwent pancreatectomy was 33 months (95% confidence interval, 25-41 months) and was not associated with RECIST response (P = .78). CONCLUSIONS: Radiographic downstaging was rare after neoadjuvant therapy, and RECIST response was not an effective treatment endpoint for patients with borderline resectable pancreatic cancer. The authors concluded that these patients should undergo pancreatectomy after initial therapy in the absence of metastases. Cancer 2012. © 2012 American Cancer Society.

Pretreatment fertility counseling and fertility preservation improve quality of life in reproductive age women with cancer.

Abstract: BACKGROUND: The post-treatment quality of life (QOL) impacts of receiving precancer-treatment infertility counseling and of pursuing fertility preservation have not been described in large-scale studies of reproductive age women with cancer. METHODS: In total, 1041 women who were diagnosed between ages 18 and 40 years responded to a retrospective survey and reported whether they received infertility counseling before cancer treatment and whether they took action to preserve fertility. Five cancer types were included: leukemia, Hodgkin disease, non-Hodgkin lymphoma, breast cancer, and gastrointestinal cancer. Validated QOL scales were used: the Decision Regret Score, the Satisfaction with Life Scale (SWLS), and the brief World Health Organization QOL questionnaire. RESULTS: Overall, 560 women (61%) who received treatment that potentially could affect fertility were counseled by the oncology team, 45 (5%) were counseled by fertility specialists, and 36 (4%) took action to preserve fertility. Pretreatment infertility counseling by a fertility specialist and an oncologist resulted in lower regret than counseling by an oncologist alone (8.4 vs 11.0; P < .0001). The addition of fertility preservation (6.6 vs 11.0; P < .0001) also was associated with even lower regret scores than counseling by an oncologist alone. Further improvements also were observed in SWLS scores with the addition of fertility specialist counseling (23.0 vs 19.8; P = .09) or preserving fertility (24.0 vs 19.0; P = .05). CONCLUSIONS: Receiving specialized counseling about reproductive loss and pursuing fertility preservation is associated with less regret and greater QOL for survivors, yet few patients are exposed to this potential benefit. Women of reproductive age should have expert counseling and should be given the opportunity to make active decisions about preserving fertility. Cancer 2011;. © 2011 American Cancer Society.

Cancer burden in Africa and opportunities for prevention.

Abstract: Cancer is an emerging public health problem in Africa. About 715,000 new cancer cases and 542,000 cancer deaths occurred in 2008 on the continent, with these numbers expected to double in the next 20 years simply because of the aging and growth of the population. Furthermore, cancers such as lung, female breast, and prostate cancers are diagnosed at much higher frequencies than in the past because of changes in lifestyle factors and detection practices associated with urbanization and economic development. Breast cancer in women and prostate cancer in men have now become the most commonly diagnosed cancers in many Sub-Saharan African countries, replacing cervical and liver cancers. In most African countries, cancer control programs and the provision of early detection and treatment services are limited despite this increasing burden. This paper reviews the current patterns of cancer in Africa and the opportunities for reducing the burden through the application of resource level interventions, including implementation of vaccinations for liver and cervical cancers, tobacco control policies for smoking-related cancers, and low-tech early detection methods for cervical cancer, as well as pain relief at the palliative stage of cancer.

The association of the BRAFV600E mutation with prognostic factors and poor clinical outcome in papillary thyroid cancer

Abstract: BACKGROUND: The effects of the BRAFV600E mutation on prognostic factors and poor clinical outcomes in papillary thyroid cancer (PTC) have not been fully quantified. The authors performed comprehensive meta-analysis to assess the strength of associations between these conditions and the BRAFV600E mutation. METHODS: The authors identified the clinical studies that examined the association of the BRAFV600E mutation in surgical specimens with clinicopathologic outcomes between January 2003 and October 2010 using the Medline database. One hundred thirty-one relevant studies were hand-searched. The authors selected 27 studies that included 5655 PTC patients. They calculated the pooled odds ratios (ORs) or risk ratios with 95% confidence intervals (CIs) for each study using a random effect model. RESULTS: The average prevalence rate of the BRAFV600E mutation was 49.4%. In 26 studies, compared with the patients who had the wild-type BRAF genes, the PTC patients with the BRAFV600E mutation had increased ORs of an extrathyroidal invasion (OR, 2.14; 95% CI, 1.68-2.73), a lymph node metastasis (OR, 1.54; 95% CI, 1.21-1.97), and an advanced TNM stage (OR, 2.00; 95% CI, 1.61-2.49). In 8 studies, patients with the mutation had 2.14-fold increased risk of recurrent and persistent disease (95% CI, 1.67-2.74). The associations were generally consistent across the different study populations. CONCLUSIONS: This meta-analysis demonstrates that the BRAFV600E mutation is closely related to the high-risk clinicopathological factors and poorer outcome of PTC. The results obtained here suggest that the BRAFV600E mutation should be considered as a poor prognostic marker in PTC and may lead to better management for individual patients.

Abstract: Purpose We conducted a systematic review and pooled analysis of small renal masses under active surveillance to identify progression risk and characteristics associated with metastases.

Upper-body morbidity after breast cancer: incidence and evidence for evaluation, prevention, and management within a prospective surveillance model of care.

Abstract: The purpose of this paper is to review the incidence of upper-body morbidity (arm and breast symptoms, impairments, and lymphedema), methods for diagnosis, and prevention and treatment strategies. It was also the purpose to highlight the evidence base for integration of prospective surveillance for upper-body morbidity within standard clinical care of women with breast cancer. Between 10% and 64% of women report upper-body symptoms between 6 months and 3 years after breast cancer, and approximately 20% develop lymphedema. Symptoms remain common into longer-term survivorship, and although lymphedema may be transient for some, those who present with mild lymphedema are at increased risk of developing moderate to severe lymphedema. The etiology of morbidity seems to be multifactorial, with the most consistent risk factors being those associated with extent of treatment. However, known risk factors cannot reliably distinguish between those who will and will not develop upper-body morbidity. Upper-body morbidity may be treatable with physical therapy. There is also evidence in support of integrating regular surveillance for upper-body morbidity into the routine care provided to women with breast cancer, with early diagnosis potentially contributing to more effective management and prevention of progression of these conditions.

Positive and negative psychosocial impact of being diagnosed with cancer as an adolescent or young adult

Abstract: BACKGROUND: The objective of this study was to explore the psychosocial impact of cancer on newly diagnosed adolescent and young adult (AYA) cancer patients. METHODS: This was a population-based, multicenter study of 523 newly diagnosed AYA survivors (ages 15-39 years) of germ cell cancer (n ¼ 204), non-Hodgkin lymphoma (n ¼ 131), Hodgkin lymphoma (n ¼ 142), acute lymphocytic leukemia (n ¼ 21), or sarcoma (n ¼ 25) from 7 National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) registries. Age at diagnosis was categorized into 3 groups (ages 15-20 years, 21-29 years, and 30-39 years). RESULTS: Respondents (43% response rate), on average (� standard deviation), were aged 29 ¼ 6.7 years, and most patients (80.1%) were not receiving treatment at the time the completed the survey. With modest differences between the age groups, the most prevalent areas of life impacted in a negative way were financial, body image, control over life, work plans, relationship with spouse/significant other, and plans for having children. Endorsement of positive life impact items also was evident across the 3 age groups, particularly with regard to relationships, future plans/goals, and health competence. CONCLUSIONS: The current results indicated that there will be future need for interventions targeting financial assistance, body image issues, relationships, and helping AYAs to attain their education objectives.

Stereotactic body radiation therapy for inoperable hepatocellular carcinoma as a local salvage treatment after incomplete transarterial chemoembolization

Abstract: BACKGROUND: The objective of this study was to evaluate the efficacy and safety of stereotactic body radiation therapy (SBRT) as a local salvage treatment after incomplete transarterial chemoembolization (TACE) for inoperable hepatocellular carcinoma (HCC). METHODS: The main eligibility criteria were a greatest tumor dimension (LD sum) <10 cm, inoperable HCC, and incomplete response after TACE. Prescribed SBRT doses were up to 60 gray (Gy) in 3 fractions, but doses were reduced until normal tissue constraints were allowed. RESULTS: Between May 2008 and February 2011, 50 patients were enrolled in this phase 2 trial, of which 47 patients were evaluable. Forty-one patients had Child-Pugh class A disease (A5/A6 were 32/9), 6 patients had class B7 disease, and 5 patients had portal vein tumor thrombosis. All patients underwent TACE 1 to 5 times before SBRT. SBRT doses ranged from 42 to 60 Gy in 3 fractions (median dose, 57 Gy), and the median LD sum was 29 mm (range, 13-78 mm). Eighteen patients (38.3%) achieved complete remission within 6 months of completing of SBRT, and 18 patients (38.3%) had a partial response. The 2-year local control rate was 94.6%, the overall survival rate was 68.7%, and the progression-free survival rate was 33.8%. Three patients (6.4%) experienced grade 3 gastrointestinal toxicity, and 2 patients (4.3%) experienced grade 4 gastric ulcer perforation. CONCLUSIONS: This trial demonstrated that SBRT after incomplete TACE for inoperable HCC achieves promising rates of response and local control. On the basis of these study results, a modified, multi-institutional, phase 2 trial to reduce gastrointestinal toxicity is recommended. Cancer 2012. © 2012 American Cancer Society.

Yoga for persistent fatigue in breast cancer survivors: a randomized controlled trial.

Abstract: BACKGROUND: Cancer-related fatigue afflicts up to 33% of breast cancer survivors, yet there are no empirically validated treatments for this symptom. METHODS: The authors conducted a 2-group randomized controlled trial to determine the feasibility and efficacy of an Iyengar yoga intervention for breast cancer survivors with persistent post-treatment fatigue. Participants were breast cancer survivors who had completed cancer treatments (other than endocrine therapy) at least 6 months before enrollment, reported significant cancer-related fatigue, and had no other medical conditions that would account for fatigue symptoms or interfere with yoga practice. Block randomization was used to assign participants to a 12-week, Iyengar-based yoga intervention or to 12 weeks of health education (control). The primary outcome was change in fatigue measured at baseline, immediately post-treatment, and 3 months after treatment completion. Additional outcomes included changes in vigor, depressive symptoms, sleep, perceived stress, and physical performance. Intent-to-treat analyses were conducted with all randomized participants using linear mixed models. RESULTS: Thirty-one women were randomly assigned to yoga (n = 16) or health education (n = 15). Fatigue severity declined significantly from baseline to post-treatment and over a 3-month follow-up in the yoga group relative to controls (P = .032). In addition, the yoga group had significant increases in vigor relative to controls (P = .011). Both groups had positive changes in depressive symptoms and perceived stress (P < .05). No significant changes in sleep or physical performance were observed. CONCLUSIONS: A targeted yoga intervention led to significant improvements in fatigue and vigor among breast cancer survivors with persistent fatigue symptoms.

Stereotactic body radiotherapy for multisite extracranial oligometastases: final report of a dose escalation trial in patients with 1 to 5 sites of metastatic disease.

Abstract: BACKGROUND: A subset of patients with metastatic cancer in limited organs may benefit from metastasis-directed therapy. The authors investigated whether patients with limited metastases could be safely treated with metastasis-directed radiotherapy. METHODS: Patients with 1 to 5 metastatic cancer sites with a life expectancy of >3 months received escalating stereotactic body radiotherapy (SBRT) doses to all known cancer sites. Patients were followed radiographically with CT scans of the chest, abdomen, and pelvis and metabolically with fluorodeoxyglucose-positron emission tomography, 1 month after treatment, and then every 3 months. Acute toxicities were scored using the National Cancer Institute's Common Terminology Criteria for Adverse Events version 3.0, and late toxicities were scored using the Radiation Therapy Oncology Group late toxicity scoring system. RESULTS: Sixty-one patients with 113 metastases were enrolled from November 2004 to November 2009 on a prospective radiation dose escalation study. Median follow-up was 20.9 months. Patients tolerated treatment well; the maximal tolerated dose was not reached in any cohort. Eleven patients (18.3%) have not progressed. One and 2-year progression-free survival are 33.3% (95% confidence interval [CI], 22.8-46.1) and 22.0% (95% CI, 12.8-34.4); 1-year and 2-year overall survival are 81.5% (95% CI, 71.1-91.1) and 56.7% (95% CI, 43.9-68.9). Seventy-two percent of patients whose tumors progressed did so in limited (1-3) metastatic sites. CONCLUSIONS: Patients with 1 to 5 metastases can be safely treated to multiple body sites and may benefit from SBRT. Further investigation should focus on patient selection.

Late dysphagia after radiotherapy‐based treatment of head and neck cancer

Abstract: BACKGROUND: Changing trends in head and neck cancer (HNC) merit an understanding of the late effects of therapy, but few studies examine dysphagia beyond 2 years of treatment. METHODS: A case series was examined to describe the pathophysiology and outcomes in dysphagic HNC survivors referred for modified barium swallow (MBS) studies ≥5 years after definitive radiotherapy or chemoradiotherapy (January 2001 through May 2011). Functional measures included the penetration-aspiration scale (PAS), performance status scale–head and neck (PSS-HN), National Institutes of Health Swallowing Safety Scale (NIH-SSS), and MBS impairment profile (MBSImp). RESULTS: Twenty-nine patients previously treated with radiotherapy (38%) or chemoradiotherapy (62%) were included (median years posttreatment, 9; range, 5-19). The majority (86%) had oropharyngeal cancer; 52% were never-smokers. Seventy-five percent had T2 or T3 tumors; 52% were N+. The median age at diagnosis was 55 (range, 38-72). Abnormal late examination findings included: dysarthria/dysphonia (76%), cranial neuropathy (48%), trismus (38%), and radionecrosis (10%). MBS studies confirmed pharyngeal residue and aspiration in all dysphagic cases owing to physiologic impairment (median PAS, 8; median NIH-SSS, 10; median MBSImp, 18), whereas stricture was confirmed endoscopically in 7 (24%). Twenty-five (86%) developed pneumonia, half requiring hospitalization. Swallow postures/strategies helped 69% of cases, but no patient achieved durable improvement across functional measures at last follow-up. Ultimately, 19 (66%) were gastrostomy-dependent. CONCLUSIONS: Although functional organ preservation is commonly achieved, severe dysphagia represents a challenging late effect that may develop or progress years after radiation-based therapy for HNC. These data suggest that novel approaches are needed to minimize and better address this complication that is commonly refractory to many standard dysphagia therapies.

Adenoid cystic carcinoma of the head and neck: Incidence and survival trends based on 1973-2007 Surveillance, Epidemiology, and End Results data.

Abstract: BACKGROUND: Adenoid cystic carcinoma (ACC) of the head and neck (ACCHN) is a rare tumor of minor salivary, parotid, and submandibular glands. The biologic behavior of the disease is poorly understood, and nonsurgical treatment strategies have yet to be standardized. The long-term prognosis continues to be guarded, with an estimated 10-year survival of <60%. Population-based studies examining ACC are scarce. The authors aimed to analyze incidence rates and survival outcomes for patients diagnosed with ACCHN using national population-based data. METHODS: Data were obtained from the US National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. Newly diagnosed ACCHN cases reported to SEER from 1973 through 2007 were categorized according to their sex, race, age, year of diagnosis, marital status, treatment interventions, primary tumor site, and disease stage. Incidence of ACCHN and postdiagnosis survival were examined over time and compared across different demographic and disease-related categories. RESULTS: The authors identified 3026 patients with ACCHN. The mean age at diagnosis among those cases was 57.4 years (range, 11-99 years). Analyses of incidence data demonstrated a decline in ACCHN rates between 1973 and 2007, noted across all sexes and races with no detectable inflexion points. The overall 5-year, 10-year, and 15-year survival outcomes for ACCHN patients were 90.3%, 79.9%, and 69.2%, respectively. Females, patients with localized disease, and younger patients were found to have significantly better survival across all time periods (all comparison-specific log-rank P values <0.001). Multivariate analyses revealed better prognosis among women compared with men (hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.65-0.82), among married compared with unmarried individuals (HR, 0.81; 95% CI, 0.71-0.91), with certain sites of origin and stage of disease (HR, 2.788; 95% CI, 2.36-3.29), and in those who had surgery of the primary tumor site (HR, 0.45; 95% CI, 0.37-0.54). CONCLUSIONS: The overall incidence of ACC is declining. The noted differences in survival based on sex, marital status, site of origin, and treatment intervention require further investigation.

Health status of adolescent and young adult cancer survivors

Abstract: BACKGROUND: Adolescents and young adults (AYA) ages 15 to 29 years who are diagnosed with cancer are at risk for long-term morbidity and mortality associated with treatment of their cancer and the cancer itself. In this article, the authors describe the self-reported health status of AYA cancer survivors. METHODS: The authors examined 2009 data from the Behavioral Risk Factor Surveillance System, including demographic characteristics, risk behaviors, chronic conditions, health status, and health care access, among AYA cancer survivors compared with respondents who had no history of cancer. RESULTS: The authors identified 4054 AYA cancer survivors and 345,592 respondents who had no history of cancer. AYA cancer survivors, compared with respondents who had no history of cancer, reported a significantly higher prevalence of current smoking (26% vs 18%); obesity (31% vs 27%); chronic conditions, including cardiovascular disease (14% vs 7%), hypertension (35% vs 29%), asthma (15% vs 8%), disability (36% vs 18%), and poor mental health (20% vs 10%) and physical health (24% vs 10%); and not receiving medical care because of cost (24% vs 15%). CONCLUSIONS: AYA cancer survivors commonly reported adverse behavioral, medical, and health care access characteristics that may lead to poor long-term medical and psychosocial outcomes. Increased adherence to established follow-up guidelines may lead to improved health among AYA cancer survivors. Cancer 2012. © 2012 American Cancer Society.

Plasma microRNA 210 levels correlate with sensitivity to trastuzumab and tumor presence in breast cancer patients

Abstract: BACKGROUND Trastuzumab is part of the standard treatment for HER-2 positive breast cancer patients, but not all patients respond to trastuzumab. Altered expression levels for microRNAs in cancer cells have been correlated with prognosis and response to chemotherapy. We hypothesized that altered expression levels for miRNAs in plasma are associated with sensitivity to trastuzumab in patients with HER-2 positive breast cancer.

Comparison of tumor response by Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST in patients treated with sorafenib for hepatocellular carcinoma.

Abstract: BACKGROUND: A significant improvement in overall survival (OS) was demonstrated in patients with advanced hepatocellular carcinoma (HCC) who received sorafenib (Sor) in the Sorafenib HCC Assessment Randomized Protocol (SHARP) study, in contrast to a response rate (RR) of 2% assessed according to Response Evaluation Criteria in Solid Tumors (RECIST). Modified RECIST (mRECIST) were developed to assess the response in patients with HCC, based on measurement of viable tumor with arterial enhancement on a computed tomography (CT) scan. In the current study, mRECIST were evaluated and were compared with RECIST in patients who received Sor for advanced HCC. METHODS: The authors retrospectively analyzed 53 patients who received Sor for advanced HCC. Patients must to have undergone a 4-phase CT scan before treatment and repeatedly thereafter. CT scans were analyzed using RECIST 1.1 and mRECIST. RESULTS: The rates of objective response (OR), stable disease (SD), and progressive disease (PD) were 2%, 79%, and 19%, respectively, according to RECIST and 23%, 57%, and 21%, respectively, according to mRECIST (P < .001). Patients who achieved an OR according to mRECIST had a longer OS than nonresponding patients with SD or PD (median OS, 18 months and 8 months, respectively; P = .013). In the 42 patients who achieved SD according to RECIST, OS differed depending on tumor response according to mRECIST, with a median OS of 17 months, 10 months, and 4 months for patients who achieved an OR (n = 11), SD (n = 29), and PD (n = 2), respectively (P = .016). CONCLUSIONS: The current series validated mRECIST in patients who received Sor for advanced HCC. The majority of patients who had SD according to RECIST had a different prognosis according to mRECIST. The results indicated that, for patients with HCC, mRECIST should be used for the standard assessment of treatment efficacy, particularly in patients who are receiving antiangiogenic drugs.

Oncogene status predicts patterns of metastatic spread in treatment‐naive nonsmall cell lung cancer

Abstract: Background The discovery of distinct subsets of non-small cell lung cancer (NSCLC) characterized by activation of driver oncogenes has greatly impacted personalized therapy. We hypothesized that the dominant oncogene in NSCLC would be associated with distinct patterns of metastatic spread in NSCLC at the time of diagnosis.

Early stage squamous cell cancer of the oral tongue—clinicopathologic features affecting outcome

Abstract: BACKGROUND: The objective of this study was to report the authors' experience in the management of patients with early stage squamous cell cancer (SCC) of the oral tongue and determine clinicopathologic factors predictive of outcome. METHODS: Two hundred sixteen patients with early stage (cT1T2N0) SCC of the oral tongue were identified from a pre-existing database of patients with oral cancer who were treated at Memorial Sloan-Kettering Cancer Center from 1985 to 2005. Patient, tumor, and treatment characteristics were recorded. Overall survival (OS), disease-specific survival (DSS), and recurrence free survival (RFS) were calculated using the Kaplan-Meier method. Predictors of outcome were identified using multivariate analysis. RESULTS: With a median follow-up of 80 months (range, 1-186 months), the 5-year DSS, OS, and RFS rates were 86%, 79%,and 70%, respectively. Local, neck, and distant recurrences occurred in 24 patients (11%), 40 patients (18%), and 5 patients (2%), respectively. Multivariate analysis identified occult neck metastases as the main independent predictor of OS, DSS, and RFS; patients who had occult metastases had a 5-fold increased risk of dying of disease compared with patients who did not have occult metastases (5-year DSS, 85.5% vs 48.5%; P = .001). A positive surgical margin was the main independent predictor for local RFS (91% vs 66% for a negative surgical margin; P = .0004), and depth of invasion was the main predictor for neck RFS (91% vs 73% for depth of invasion 2 mm, respectively; P = .02). CONCLUSIONS: In the authors' experience, patients with early stage oral tongue cancer have excellent outcomes. In the current study, the presence of occult metastases was the main predictor of survival outcome. Cancer 2012;. © 2011 American Cancer Society.

Does skin cancer screening save lives?: an observational study comparing trends in melanoma mortality in regions with and without screening.

Abstract: BACKGROUND: From July 1, 2003 to June 30, 2004, a population-based skin cancer screening project was conducted in Schleswig-Holstein, Germany. In total, 360,288 individuals aged ≥20 years were screened by means of a whole-body examination. In this report, the authors compare trends in melanoma mortality in Schleswig-Holstein with those in all adjacent regions, none of which had population-based skin cancer screening. METHODS: Trends in melanoma mortality rates for Schleswig-Holstein and the adjacent regions (Denmark and the German federal states of Mecklenburg-Vorpommern, Hamburg, and Lower Saxony) and in Germany excluding Schleswig-Holstein were compared. Log-linear regression was used to assess mortality trends. RESULTS: In Schleswig-Holstein during the pre skin cancer screening period (1998-1999), the age-standardized melanoma mortality rate (World standard population) was 1.9 per 100,000 for men and 1.4 per 100,000 for women. Melanoma mortality declined by 47% to 1.0 per 100,000 men and by 49% to 0.7 per 100,000 women by 2008/2009. The annual percentage change in the most recent 10-year period (2000-2009) was −7.5% (95% confidence interval, −14.0, −0.5) for men and −7.1% (95% confidence interval, −10.5, −2.9) for women. In each of the 4 adjacent regions and in the rest of Germany, mortality rates were stable, and the decline in Schleswig-Holstein was significantly different from the changes observed in all of the other areas studied. CONCLUSIONS: The current data represent strong evidence, but not absolute proof, that the skin cancer screening program produced a reduction in melanoma mortality in Schleswig-Holstein.

Estimations of the increasing prevalence and plateau prevalence of chronic myeloid leukemia in the era of tyrosine kinase inhibitor therapy.

Abstract: BACKGROUND: The annual incidence of chronic myeloid leukemia (CML) in the United States is approximately 4800 cases. With the success of tyrosine kinase inhibitor (TKI) therapy, the all-cause annual mortality rate was reduced to 2%. Therefore, the prevalence of CML is increasing over time. Estimating the CML prevalence and plateau prevalence is important in the implementation of health care strategies and future therapeutic trials. The objective of this report was to estimate the increasing prevalence and plateau prevalence of CML in future years. METHODS: The prevalence of CML was estimated based on several parameters: the annual mortality rate on TKI therapy compared with a age-matched, normal population; the incidence of CML; the anticipated population growth in the United States; and aging of the population. RESULTS: On the basis of these calculations, the mortality ratio of patients with CML compared with an age-matched normal population was approximately 1.53. The estimated prevalence of CML is approximately 70,000 in 2010, 112,000 in 2020, 144,000 in 2030, 167,000 in 2040, and 181,000 in 2050, when it will reach a near plateau prevalence. CONCLUSIONS: The current results indicated that the prevalence of CML will continue to increase to reach a near plateau prevalence 35 times the annual incidence. These estimates should be considered in health care policies and in the design of future studies in CML. Cancer 2012;118: 3123–27. © 2012 American Cancer Society.

Cancer-related fatigue: implications for breast cancer survivors.

Abstract: Cancer-related fatigue (CRF) has been documented as 1 of the most distressing symptoms reported by breast cancer survivors. CRF affects functioning and impacts quality of life. Possible causal factors include physical conditions, affective and cognitive states, proinflammatory cytokines, and metabolic factors. Several common problems are associated with CRF in women with breast cancer, including treatment side effects, obesity, arm/upper quadrant symptoms, sleep disturbances, psychological effects, and comorbid conditions. In this article, the authors review the state of the knowledge regarding these issues and nonpharmacologic and pharmacologic interventions for CRF. Physical activity and psychosocial interventions are recommended for practice. Numerous limitations of past studies need to be considered in the design of future studies. CRF is prevalent in preoperative, postoperative, and ongoing surveillance phases. Throughout the continuum of care for women with breast cancer, clinicians must screen, further assess as indicated, and treat CRF, because it is associated with emotional distress and limits function and willingness to exercise.

Extracapsular spread and adjuvant therapy in human papillomavirus-related, p16-positive oropharyngeal carcinoma.

Abstract: BACKGROUND: Extracapsular spread (ECS) is commonly used to justify adjuvant chemotherapy in patients with head and neck cancer The role of ECS as a prognosticator and adjuvant therapy determinant in surgically resected, human papillomavirus-related oropharyngeal squamous cell carcinoma (OPSCC), however, has never been determined METHODS: Of 210 oropharynx patients in a prospective transoral laser microsurgery database, 152 patients who had p16-positive primary OPSCC and pathologically positive necks were eligible for the study ECS was measured from routine reporting (ECSreport) and by using a novel histologic grading system (ECSgraded) Proportional hazards models and matched analyses were used to compare the impact of ECS and adjuvant therapy on disease-free survival (DFS) Patients with and without graded ECS were matched for T-stage, surgical margins, and adjuvant therapy RESULTS: At a median follow-up of 43 months, the presence of ECS was not associated with poorer DFS in multivariate analyses (ECSreport: hazard ratio [HR], 342; 95% confidence interval [CI], 045-2588; P = 23; ECSgraded: HR, 254; 95% CI, 088-734; P = 09) T-stage and high-grade ECS, ie soft tissue metastasis (STMgraded) were prognostic Overall and in the presence of ECS or even STM, adjuvant CRT was not associated with better DFS over radiotherapy alone (HR, 025; 95% CI, 006-113; P = 07) In addition, matched analyses demonstrated no significant reduction in DFS for the presence of ECS versus the absence of ECS or reduced DFS for the administration of adjuvant radiotherapy alone versus CRT in ECS-positive patients CONCLUSIONS: Routinely reported ECS was not prognostic in this study Adjuvant CRT versus radiotherapy alone produced no improvement in DFS for ECS-positive patients The authors propose that de-escalated adjuvant therapy should be considered for patients with p16-positive OPSCC who undergo surgery and that routinely reported ECS should not be used to justify adjuvant chemotherapy Cancer 2012;3519–3530 © 2011 American Cancer Society

Intratumoral neutrophils and plasmacytoid dendritic cells indicate poor prognosis and are associated with pSTAT3 expression in AJCC stage I/II melanoma.

Abstract: BACKGROUND: Tumor cell and host immune cell interaction plays a key role in carcinogenesis. Signal transducer and activator of transcription 3 (STAT3) is constitutively activated in cancer and believed to be an important mediator of tumor-induced immunosuppression. This paper aims to describe the prognostic impact of neutrophil and dendritic cell infiltration in primary melanoma and the association of this infiltration with activated STAT3 (pSTAT3) in primary melanoma cells. METHODS: Formalin-fixed, paraffin-embedded primary melanomas from 186 stage-I/II melanoma patients surgically resected from 1997 to 2000. Infiltrating neutrophils (CD66b), dendritic cells (CD123+ and DC-LAMP+), T-lymphocytes (CD8) and pSTAT3 melanoma cell expression were studied by immunohistochemistry and evaluated as present or absent. DC-LAMP+ cell infiltration was evaluated as absent/few versus dense. Study endpoints: relapse-free survival, melanoma-specific, and overall survival. RESULTS: The median observation time was 12.2 years (range, 10.4-14.2 years). Fifty-one deaths were observed of which 38 (20%) were melanoma-specific. In a multivariate Cox proportional hazards model including ulceration and melanoma thickness, neutrophil and CD123+ dendritic cell infiltration were independently associated with poor prognosis (CD66b: hazard ratio [HR] = 3.13; 95% confidence interval [CI], 1.43-6.83; P = .004; CD123: HR = 2.45; 95% CI, 1.22-4.92; P = .012). The association between melanoma cell pSTAT3 expression and immune infiltration (neutrophils and CD123+ cells) was strong. pSTAT3 expression, CD8 and DC-LAMP infiltration were not independently associated with poor prognosis. CONCLUSIONS: Neutrophil infiltration and CD123+ dendritic cell infiltration in primary melanoma are independently associated with poor prognosis. Melanoma cell expression of pSTAT3 is strongly associated with the surrounding immune infiltrate. Cancer 2012;. © 2011 American Cancer Society.

A prospective surveillance model for rehabilitation for women with breast cancer

Abstract: BACKGROUND: The current model of care for individuals with breast cancer focuses on treatment of the disease, followed by ongoing surveillance to detect recurrence. This approach lacks attention to patients' physical and functional well-being. Breast cancer treatment sequelae can lead to physical impairments and functional limitations. Common impairments include pain, fatigue, upper-extremity dysfunction, lymphedema, weakness, joint arthralgia, neuropathy, weight gain, cardiovascular effects, and osteoporosis. Evidence supports prospective surveillance for early identification and treatment as a means to prevent or mitigate many of these concerns. This article proposes a prospective surveillance model for physical rehabilitation and exercise that can be integrated with disease treatment to create a more comprehensive approach to survivorship health care. The goals of the model are to promote surveillance for common physical impairments and functional limitations associated with breast cancer treatment; to provide education to facilitate early identification of impairments; to introduce rehabilitation and exercise intervention when physical impairments are identified; and to promote and support physical activity and exercise behaviors through the trajectory of disease treatment and survivorship. METHODS: The model is the result of a multidisciplinary meeting of research and clinical experts in breast cancer survivorship and representatives of relevant professional and advocacy organizations. RESULTS/CONCLUSIONS: The proposed model identifies time points during breast cancer care for assessment of and education about physical impairments. Ultimately, implementation of the model may influence incidence and severity of breast cancer treatment-related physical impairments. As such, the model seeks to optimize function during and after treatment and positively influence a growing survivorship community. (Less)

Intramural and extramural vascular invasion in colorectal cancer: prognostic significance and quality of pathology reporting

Abstract: BACKGROUND: Blood vessel invasion has been associated with poor outcome in colorectal cancer (CRC), whereas the prognostic impact of lymphatic invasion is less clear The authors of this report evaluated venous and lymphatic invasion as potential prognostic indicators in patients with CRC focusing on lymph node-negative patients and compared routine and review pathology diagnoses METHODS: In total, 381 tumors from randomly selected patients were retrospectively reviewed The presence of vascular invasion was related to disease-free and cancer-specific survival using the Kaplan-Meier method For multivariable analysis, Cox proportional hazards regression models were performed RESULTS: Lymphatic invasion and venous invasion were observed in 126 patients (33%) and 87 patients (23%), respectively, and were associated significantly with tumor classification, lymph node status, American Joint Committee on Cancer/International Union Against Cancer (AJCC/UICC) disease stage, tumor differentiation, pattern of invasion, and extent of tumor budding The detection of vascular invasion was related to the number of examined tissue blocks Venous and lymphatic invasion proved to be significant prognostic variables in univariable and multivariable analyses Extramural vascular involvement was of particular significance When the analysis was restricted to patients with (AJCC/UICC) stage II disease, venous invasion, but not lymphatic invasion, was identified as an independent prognostic variable Review pathology diagnoses differed significantly from routine diagnoses with respect to prognostic impact CONCLUSIONS: Venous and lymphatic invasion proved to be significant prognostic variables in patients with CRC The detection of vascular invasion and, consequently, risk stratification of affected patients were related to the quality of pathology workup, ie, the number of examined tissue blocks Observed differences between review and routine pathology diagnoses illustrated the need for high-quality pathology reporting and also for standardized quality control Cancer 2012; © 2011 American Cancer Society

Incidence of soft tissue sarcoma and beyond: a population-based prospective study in 3 European regions.

Abstract: BACKGROUND: The objectives of this study were to measure the incidence of sarcomas, including viscerally sited tumors that are not reported in cancer statistics, and to draw explanatory clues from a large and reliable sarcoma incidence data set. METHODS: Cases of sarcomas regardless of primary site (except bone and joints) were collected during 2 years in 3 European regions totaling approximately 26,000,000 person-years. The sources used were pathology reports and hospital discharges forms. Diagnoses were reviewed by expert sarcoma pathologists and were classified according to 2002 World Health Organization criteria. Soft tissue sarcomas (STS) were considered those located in arms, legs, trunk, head, neck, and retroperitoneum; visceral sarcomas (VS) were considered those that arose in internal organs. Rates were age standardized using the European (ASR-E) and the USA standard population. The rate of coexistence of VS and STS was calculated by dividing the 2 corresponding ASRs. RESULTS: There were 1558 sarcomas, 968 STS, and 590 VS. The ASRs-USA per 100,000 person-years was 5.12 × 105 among males and 4.58 × 105 among females for all sarcomas. For males and females, respectively, the ASR-E per 100,000 person-years was 3.58 × 105 and 2.55 × 105, respectively, for STS; 1.47 × 105 and 1.97 × 105, respectively, for VS; and 0.55 × 105 and 0.10 × 105, respectively, for Kaposi sarcoma. The coexistence rate of VS and STS was 0.41 for males and 0.77 for females. For dermatofibrosarcoma (both sexes), uterine sarcoma, liposarcoma (females), and leiomyosarcoma, including or excluding the uterus (females), the age-specific rates depicted a curve with a rapid increasing trend until ages 40 to 50 years and little variation thereafter. CONCLUSIONS: Compared with the incidence of STS, VS incidence made up an additional 41% in males and 77% in females. Because the shape of age-specific curves for some histotypes was similar to that of breast cancer, the authors concluded that sex hormones (plus many chemicals that act as endocrine disruptors) may be involved in carcinogenesis. This evidence could pave the way to investigate alternative treatments and to explore etiology. Cancer 2012. © 2012 American Cancer Society.
