TL;DR: The magnitude of the decline in cancer death rates from 1991 to 2010 varies substantially by age, race, and sex, ranging from no decline among white women aged 80 years and older to a 55% decline among black men aged 40 years to 49 years.
Abstract: Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths that will occur in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival. Incidence data were collected by the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data were collected by the National Center for Health Statistics. A total of 1,665,540 new cancer cases and 585,720 cancer deaths are projected to occur in the United States in 2014. During the most recent 5 years for which there are data (2006-2010), delay-adjusted cancer incidence rates declined slightly in men (by 0.6% per year) and were stable in women, while cancer death rates decreased by 1.8% per year in men and by 1.4% per year in women. The combined cancer death rate (deaths per 100,000 population) has been continuously declining for 2 decades, from a peak of 215.1 in 1991 to 171.8 in 2010. This 20% decline translates to the avoidance of approximately 1,340,400 cancer deaths (952,700 among men and 387,700 among women) during this time period. The magnitude of the decline in cancer death rates from 1991 to 2010 varies substantially by age, race, and sex, ranging from no decline among white women aged 80 years and older to a 55% decline among black men aged 40 years to 49 years. Notably, black men experienced the largest drop within every 10-year age group. Further progress can be accelerated by applying existing cancer control knowledge across all segments of the population.

TL;DR: The number of cancer survivors continues to increase due to the aging and growth of the population and improvements in early detection and treatment, and current treatment patterns for the most common cancer types are described based on information in the National Cancer Data Base and the SEER and SEER‐Medicare linked databases.
Abstract: The number of cancer survivors continues to increase due to the aging and growth of the population and improvements in early detection and treatment. In order for the public health community to better serve these survivors, the American Cancer Society and the National Cancer Institute collaborated to estimate the number of current and future cancer survivors using data from the Surveillance, Epidemiology, and End Results (SEER) program registries. In addition, current treatment patterns for the most common cancer types are described based on information in the National Cancer Data Base and the SEER and SEER-Medicare linked databases; treatment-related side effects are also briefly described. Nearly 14.5 million Americans with a history of cancer were alive on January 1, 2014; by January 1, 2024, that number will increase to nearly 19 million. The 3 most common prevalent cancers among males are prostate cancer (43%), colorectal cancer (9%), and melanoma (8%), and those among females are cancers of the breast (41%), uterine corpus (8%), and colon and rectum (8%). The age distribution of survivors varies substantially by cancer type. For example, the majority of prostate cancer survivors (62%) are aged 70 years or older, whereas less than one-third (32%) of melanoma survivors are in this older age group. It is important for clinicians to understand the unique medical and psychosocial needs of cancer survivors and to proactively assess and manage these issues. There are a growing number of resources that can assist patients, caregivers, and health care providers in navigating the various phases of cancer survivorship.

TL;DR: Progress in reducing colorectal cancer death rates can be accelerated by improving access to and use of screening and standard treatment in all populations, including the most current data on incidence, survival, and mortality rates and trends.
Abstract: Colorectal cancer is the third most common cancer and the third leading cause of cancer death in men and women in the United States. This article provides an overview of colorectal cancer statistics, including the most current data on incidence, survival, and mortality rates and trends. Incidence data were provided by the National Cancer Institute's Surveillance, Epidemiology, and End Results program and the North American Association of Central Cancer Registries. Mortality data were provided by the National Center for Health Statistics. In 2014, an estimated 71,830 men and 65,000 women will be diagnosed with colorectal cancer and 26,270 men and 24,040 women will die of the disease. Greater than one-third of all deaths (29% in men and 43% in women) will occur in individuals aged 80 years and older. There is substantial variation in tumor location by age. For example, 26% of colorectal cancers in women aged younger than 50 years occur in the proximal colon, compared with 56% of cases in women aged 80 years and older. Incidence and death rates are highest in blacks and lowest in Asians/Pacific Islanders; among males during 2006 through 2010, death rates in blacks (29.4 per 100,000 population) were more than double those in Asians/Pacific Islanders (13.1) and 50% higher than those in non-Hispanic whites (19.2). Overall, incidence rates decreased by approximately 3% per year during the past decade (2001-2010). Notably, the largest drops occurred in adults aged 65 and older. For instance, rates for tumors located in the distal colon decreased by more than 5% per year. In contrast, rates increased during this time period among adults younger than 50 years. Colorectal cancer death rates declined by approximately 2% per year during the 1990s and by approximately 3% per year during the past decade. Progress in reducing colorectal cancer death rates can be accelerated by improving access to and use of screening and standard treatment in all populations.

TL;DR: An overview of female breast cancer statistics in the United States, including data on incidence, mortality, survival, and screening is provided, with African American women having the poorest breast cancer survival of any racial/ethnic group.
Abstract: In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including data on incidence, mortality, survival, and screening. Approximately 232,340 new cases of invasive breast cancer and 39,620 breast cancer deaths are expected to occur among US women in 2013. One in 8 women in the United States will develop breast cancer in her lifetime. Breast cancer incidence rates increased slightly among African American women; decreased among Hispanic women; and were stable among whites, Asian Americans/Pacific Islanders, and American Indians/Alaska Natives from 2006 to 2010. Historically, white women have had the highest breast cancer incidence rates among women aged 40 years and older; however, incidence rates are converging among white and African American women, particularly among women aged 50 years to 59 years. Incidence rates increased for estrogen receptor-positive breast cancers in the youngest white women, Hispanic women aged 60 years to 69 years, and all but the oldest African American women. In contrast, estrogen receptor-negative breast cancers declined among most age and racial/ethnic groups. These divergent trends may reflect etiologic heterogeneity and the differing effects of some factors, such as obesity and parity, on risk by tumor subtype. Since 1990, breast cancer death rates have dropped by 34% and this decrease was evident in all racial/ethnic groups except American Indians/Alaska Natives. Nevertheless, survival disparities persist by race/ethnicity, with African American women having the poorest breast cancer survival of any racial/ethnic group. Continued progress in the control of breast cancer will require sustained and increased efforts to provide high-quality screening, diagnosis, and treatment to all segments of the population.

TL;DR: Estimates of the number of new cancer cases and deaths for children and adolescents in the United States are provided and an overview of risk factors, symptoms, treatment, and long‐term and late effects for common pediatric cancers are provided.
Abstract: In this article, the American Cancer Society provides estimates of the number of new cancer cases and deaths for children and adolescents in the United States and summarizes the most recent and comprehensive data on cancer incidence, mortality, and survival from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries (which are reported in detail for the first time here and include high-quality data from 45 states and the District of Columbia, covering 90% of the US population). In 2014, an estimated 15,780 new cases of cancer will be diagnosed and 1960 deaths from cancer will occur among children and adolescents aged birth to 19 years. The annual incidence rate of cancer in children and adolescents is 186.6 per 1 million children aged birth to 19 years. Approximately 1 in 285 children will be diagnosed with cancer before age 20 years, and approximately 1 in 530 young adults between the ages of 20 and 39 years is a childhood cancer survivor. It is therefore likely that most pediatric and primary care practices will be involved in the diagnosis, treatment, and follow-up of young patients and survivors. In addition to cancer statistics, this article will provide an overview of risk factors, symptoms, treatment, and long-term and late effects for common pediatric cancers.

TL;DR: The American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries collaborate annually to provide updates on cancer incidence and death rates and trends in these outcomes for the United States.
Abstract: BACKGROUND: 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) collaborate annually to provide updates on cancer incidence and death rates and trends in these outcomes for the United States. This year’s report includes the prevalence of comorbidity at the time of first cancer diagnosis among patients with lung, colorectal, breast, or prostate cancer and survival among cancer patients based on comorbidity level. METHODS: Data on cancer incidence were obtained from the NCI, the CDC, and the NAACCR; and data on mortality were obtained from the CDC. Long-term (1975/1992-2010) and short-term (2001-2010) trends in age-adjusted incidence and death rates for all cancers combined and for the leading cancers among men and women were examined by joinpoint analysis. Through linkage with Medicare claims, the prevalence of comorbidity among cancer patients who were diagnosed between 1992 through 2005 residing in 11 Surveillance, Epidemiology, and End Results (SEER) areas were estimated and compared with the prevalence in a 5% random sample of cancer-free Medicare beneficiaries. Among cancer patients, survival and the probabilities of dying of their cancer and of other causes by comorbidity level, age, and stage were calculated. RESULTS: Death rates continued to decline for all cancers combined for men and women of all major racial and ethnic groups and for most major cancer sites; rates for both sexes combined decreased by 1.5% per year from 2001 through 2010. Overall incidence rates decreased in men and stabilized in women. The prevalence of comorbidity was similar among cancer-free Medicare beneficiaries (31.8%), breast cancer patients (32.2%), and prostate cancer patients (30.5%); highest among lung cancer patients (52.9%); and intermediate among colorectal cancer patients (40.7%). Among all cancer patients and especially for patients diagnosed with local and regional disease, age and comorbidity level were important influences on the probability of dying of other causes and, consequently, on overall survival. For patients diagnosed with distant disease, the probability of dying of cancer was much higher than the probability of dying of other causes, and age and comorbidity had a smaller effect on overall survival. CONCLUSIONS: Cancer death rates in the United States continue to decline. Estimates of survival that include the probability of dying of cancer and other causes stratified by comorbidity level, age, and stage can provide important information to facilitate treatment decisions.

TL;DR: With the number of annual cancer cases and deaths likely to increase by at least 70% by 2030, there is a pressing need for a coordinated approach to improving the extent and quality of services for cancer control in Africa, and better surveillance systems with which they can be planned and monitored.
Abstract: Background:Non-communicable diseases, and especially cancers, are recognized as an increasing problem for low- and middle income countries. Effective control programmes require adequate information on the size, nature, and evolution of the health problem which they pose. Methods:We present estimates of the incidence and mortality of cancer in Africa in 2012, derived from "Globocan 2012", published by the International Agency for Research on Cancer. Results: There were 847,000 new cancer cases (6% of the world total) and 591,000 deaths (7.2% of the world total) in the 54 countries of Africa in 2012. While the cancer profiles often differ markedly between regions, the most common cancers in men were prostate (16.4% of new cancers), liver (10.7%) and Kaposi sarcoma (6.7%); in women, by far the most important are cancers of the breast (27.6% of all cancers) and cervix uteri (20.4%). Conclusions: These results are based on the best data currently available, and provide a reasonable appraisal of the cancer situation in Africa. With the number of annual cancer cases and deaths likely to increase by at least 70% by 2030 there is a pressing need for a coordinated approach to improving the extent and quality of services for cancer control in Africa, and better surveillance systems with which they can be planned and monitored. Impact:The need for developing cancer surveillance systems in Africa for planning and monitoring cancer prevention and control in the region.

TL;DR: In a large nationwide hospital-based dataset, higher odds of having TN breast cancer in black women and of HER2-overexpressing in API compared with white women in every level of SES are found.
Abstract: To estimate the odds of breast cancer subtypes in minority populations versus non-Hispanic (NH) whites stratified by socioeconomic status (SES) [a composite of individual-level SES (insurance status) and area-level SES (median household income quartile from 2000 U.S. Census data)] using a large nationwide cancer database. We used the National Cancer Data Base to identify breast cancer cases diagnosed in 2010 and 2011, the only 2 years since U.S. cancer registries uniformly began collecting HER2 results. Breast cancer cases were classified into five subtypes based on hormone receptor (HR) and HER2 status: HR+/HER2−, HR+/HER2+, HR−/HER2+ (HER2-overexpressing), HR−/HER2− (TN), and unknown. A polytomous logistic regression was used to estimate odds ratios (ORs) comparing the odds of non-HR+/HER2-subtypes to HR+/HER2− for racial/ethnic groups controlling for and stratifying by SES, using a composite of insurance status and area-level income. Compared with NH whites, NH blacks and Hispanics were 84 % (OR = 1.84; 95 % CI 1.77–1.92) and 17 % (OR = 1.17; 95 % CI 1.11–1.24) more likely to have TN subtype versus HR+/HER2−, respectively. Asian/Pacific Islanders (API) had 1.45 times greater odds of being diagnosed with HER2-overexpressing subtype versus HR+/HER2− compared with NH whites (OR = 1.45; 95 % CI 1.31–1.61). We found similar ORs for race in high and low strata of SES. In a large nationwide hospital-based dataset, we found higher odds of having TN breast cancer in black women and of HER2-overexpressing in API compared with white women in every level of SES.

TL;DR: A first overview on MFS in a large cohort of female BC patients (1,070 patients) from sub‐Saharan Africa is presented, with young age and advanced stage associated with poor outcome.
Abstract: There is little information on breast cancer (BC) survival in Ethiopia and other parts of sub-Saharan Africa. Our study estimated cumulative probabilities of distant metastasis-free survival (MFS) in patients at Addis Ababa (AA) University Radiotherapy Center, the only public oncologic institution in Ethiopia. We analyzed 1,070 females with BC stage 1-3 seen in 2005-2010. Patients underwent regular follow-up; estrogen receptor-positive and -unknown patients received free endocrine treatment (an independent project funded by AstraZeneca Ltd. and facilitated by the Axios Foundation). The primary endpoint was distant metastasis. Sensitivity analysis (worst-case scenario) assumed that patients with incomplete follow-up had events 3 months after the last appointment. The median age was 43.0 (20-88) years. The median tumor size was 4.96 cm [standard deviation (SD) 2.81 cm; n = 709 information available]. Stages 1, 2 and 3 represented 4, 25 and 71%, respectively (n = 644). Ductal carcinoma predominated (79.2%, n = 1,070) as well as grade 2 tumors (57%, n = 509). Median follow-up was 23.1 (0-65.6) months, during which 285 women developed metastases. MFS after 2 years was 74% (69-79%), declining to 59% (53-64%) in the worst-case scenario. Patients with early stage (1-2) showed better MFS than patients with stage 3 (85 and 66%, respectively). The 5-year MFS was 72% for stages 1 and 2 and 33% for stage 3. We present a first overview on MFS in a large cohort of female BC patients (1,070 patients) from sub-Saharan Africa. Young age and advanced stage were associated with poor outcome.

TL;DR: Clinical-pathologic stage discrepancy in BC patients is remarkably common across the United States and should be considered when selecting patients for preoperative or nonoperative management strategies and when comparing the outcomes of bladder sparing approaches to RC.
Abstract: Purpose To examine the accuracy of clinical staging and its effects on outcome in bladder cancer (BC) patients treated with radical cystectomy (RC), using a large national database. Methods and Materials A total of 16,953 patients with BC without distant metastases treated with RC from 1998 to 2009 were analyzed. Factors associated with clinical–pathologic stage discrepancy were assessed by multivariate generalized estimating equation models. Survival analysis was conducted for patients treated between 1998 and 2004 (n=7270) using the Kaplan-Meier method and Cox proportional hazards models. Results At RC 41.9% of patients were upstaged, whereas 5.9% were downstaged. Upstaging was more common in females, the elderly, and in patients who underwent a more extensive lymphadenectomy. Downstaging was less common in patients treated at community centers, in the elderly, and in Hispanics. Receipt of preoperative chemotherapy was highly associated with downstaging. Five-year overall survival rates for patients with clinical stages 0, I, II, III, and IV were 67.2%, 62.9%, 50.4%, 36.9%, and 27.2%, respectively, whereas those for the same pathologic stages were 70.8%, 75.8%, 63.7%, 41.5%, and 24.7%, respectively. On multivariate analysis, upstaging was associated with increased 5-year mortality (hazard ratio [HR] 1.80, P P =.160). In contrast, more extensive lymphadenectomy was associated with decreased 5-year mortality (HR 0.76 for ≥10 lymph nodes examined, P P =.042). Conclusions Clinical–pathologic stage discrepancy in BC patients is remarkably common across the United States. These findings should be considered when selecting patients for preoperative or nonoperative management strategies and when comparing the outcomes of bladder sparing approaches to RC.

TL;DR: Although widespread reductions in lung cancer in young women provide evidence of tobacco control success, rates continue to increase among older women in many countries, and more concentrated efforts to initiate or expand tobacco control programs in these countries globally will be required to attenuate the future lung cancer burden.
Abstract: Background: There is no recent comprehensive global analysis of lung cancer mortality in women. We describe contemporary mortality rates and trends among women globally. Methods: We used the World Health Organization's Cancer Mortality Database covering 65 populations on six continents to calculate age-standardized (1960 Segi world standard) lung cancer death rates during 2006 to 2010 and annual percent change in rates for available years from 1985 to 2011 and for the most recent five data years by population and age group (30–49 and 50–74 years). Results: Lung cancer mortality rates (per 100,000) among young women (30–49 years) during 2006 to 2010 ranged from 0.7 in Costa Rica to 14.8 in Hungary. Rates among young women were stable or declining in 47 of 52 populations examined. Rates among women 50 to 74 years ranged from 8.8 in Georgia and Egypt to 120.0 in Scotland. In both age groups, rates were highest in parts of Europe (Scotland, Hungary, Denmark) and North America and lowest in Africa, Asia, and Latin America. Rates in older women were increasing for more than half (36/64) of populations examined, including most countries in Southern, Eastern, and Western Europe and South America. Conclusions: Although widespread reductions in lung cancer in young women provide evidence of tobacco control success, rates continue to increase among older women in many countries. Impact: More concentrated efforts to initiate or expand tobacco control programs in these countries globally will be required to attenuate the future lung cancer burden.

TL;DR: Non-Hispanic blacks, Hispanics, and older patients diagnosed with primary metastatic colorectal cancer have not equally benefitted from the introduction and dissemination of new treatments.
Abstract: Previous studies documented significant increase in overall survival for metastatic colorectal cancer (CRC) since the late 1990s coinciding with the introduction and dissemination of new treatments. We examined whether this survival increase differed across major racial/ethnic populations and age groups. We identified patients diagnosed with primary metastatic colorectal cancer during 1992–2009 from 13 population-based cancer registries of the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program, which cover about 14 % of the US population. The 5-year cause-specific survival rates were calculated using SEER*Stat software. From 1992–1997 to 2004–2009, 5-year cause-specific survival rates increased significantly from 9.8 % (95 % CI 9.2–10.4) to 15.7 % (95 % CI 14.7–16.6) in non-Hispanic whites and from 11.4 % (95 % CI 9.4–13.6) to 17.7 % (95 % CI 15.1–20.5) in non-Hispanic Asians, but not in non-Hispanic blacks [from 8.6 % (95 % CI 7.2–10.1) to 9.8 % (95 % CI 8.1–11.8)] or Hispanics [from 14.0 % (95 % CI 11.8–16.3) to 16.4 % (95 % CI 14.0–19.0)]. By age group, survival rates increased significantly for the 20–64-year age group and 65 years or older age group in non-Hispanic whites, although the improvement in the older non-Hispanic whites was substantially smaller. Rates also increased in non-Hispanic Asians for the 20–64-year age group although marginally nonsignificant. In contrast, survival rates did not show significant increases in both younger and older age groups in non-Hispanic blacks and Hispanics. Non-Hispanic blacks, Hispanics, and older patients diagnosed with metastatic CRC have not equally benefitted from the introduction and dissemination of new treatments.

TL;DR: The relation between insurance status and survival for patients diagnosed with diffuse large B‐cell lymphoma (DLBCL), the most common subtype of NHL, is addressed.
Abstract: BACKGROUND Insurance status is associated with stage at diagnosis and treatment for non-Hodgkin lymphoma (NHL), but no previous studies have addressed the relation between insurance status and survival for patients diagnosed with diffuse large B-cell lymphoma (DLBCL), the most common subtype of NHL. METHODS The authors analyzed survival among 3858 patients with DLBCL ages 18 to 64 years who were diagnosed in 2004 using data from the National Cancer Database, a nationwide, hospital-based cancer registry. Kaplan-Maier curves were compared between patients who had private insurance, Medicaid, and no insurance. Cox proportional hazards models were fitted to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for insurance controlling for age, sex, race, area-level socioeconomic status, and potential mediators of the association between insurance status and survival, including stage at diagnosis, B-symptoms, comorbidity, and treatment. RESULTS After adjusting for sociodemographic factors, uninsured patients (HR, 1.39; 95% CI, 1.14-1.70) and Medicaid-insured patients (HR, 1.48; 95% CI, 1.23-1.78) with DLBCL had lower survival compared with patients who had private insurance. This association was attenuated after adjusting for the potential mediators (for uninsured patients, HR, 1.18 [95% CI, 0.96-1.44]; for Medicaid-insured patients, HR, 1.27 [95% CI, 1.06-1.53]). CONCLUSIONS Uninsured and Medicaid-insured patients with DLBCL had inferior survival compared with privately insured patients. These associations can be explained in part because uninsured/Medicaid-insured patients who have DLBCL present with more advanced-stage disease and comorbid illnesses and less commonly receive standard treatment. Access to affordable and adequate health care has the potential to improve survival for patients with DLBCL. Cancer 2014;120:1220–1227. © 2014 American Cancer Society.

TL;DR: Using data from household interviews obtained in the nationally representative Medical Expenditure Panel Survey in the United States, it is unknown whether dependent-coverage expansion has improved the use of recommended preventive services in this age group.
Abstract: To the Editor: Since it officially went into effect on September 23, 2010, dependent-coverage expansion under the Affordable Care Act (ACA), which allows young adults to be covered under a parent's health insurance plan until they turn 26 years of age, has substantially improved the insurance coverage of persons between the ages of 19 and 25 years.1–4 However, it is unknown whether dependent-coverage expansion has improved the use of recommended preventive services in this age group. Using data from household interviews obtained in the nationally representative Medical Expenditure Panel Survey in the United States, we examined the use of . . .

TL;DR: Since the majority of patients showed ER-positive BC, Tamoxifen-therapy should be given to all patients even with unknown ER status, and they have clinical implications for management of BC patients in Ethiopia and other parts of sub-Saharan Africa where ER-status is not ascertained as part of routine management of the disease.
Abstract: In contrast with breast cancers (BCs) in other parts of the world, most previous studies reported that the majority of BCs in sub-Saharan Africa are estrogen-receptor (ER) negative. However, a recent study using the US SEER database showed that the proportion of ER-negative BC is comparable between US-born blacks and West-African born blacks but substantially lower in East African-born blacks, with over 74% of patients Ethiopians or Eritreans. In this paper, we provide the first report on the proportion of ER-negative BC in Ethiopia, and the relation to progesterone-receptor (PgR) status. We analysed 352 female patients with ER results available out of 1208 consecutive female BC patients treated at Addis Ababa-University Hospital, Ethiopia, from June 2005 through December 2010. The influences of age, stage, and histology on the probability of ER-negative tumours were assessed by a log-linear regression model. Of the 352 patients, only 35% were ER-negative. The proportion of ER-negative tumours decreased with advancing age at diagnosis and was not affected by histology or stage. For age, the proportion decreased by 6% for each additional 5 years (stage-adjusted prevalence ratio PR = 0.94, 95% CI: 0.89–1.00). About 31% were ER- and PgR-negative, and 69% were ER- and/or PgR-positive. Contrary to most previous reports in other parts of sub-Saharan Africa, the majority of patients in Ethiopia are ER-positive rather than ER-negative. These findings are in line with low proportions of ER-negative BCs from East African immigrants within the SEER database, and they have clinical implications for management of BC patients in Ethiopia and other parts of sub-Saharan Africa where ER-status is not ascertained as part of routine management of the disease. Since the majority of patients showed ER-positive BC, Tamoxifen-therapy should be given to all patients even with unknown ER status.

TL;DR: Lower levels of CRC and mammography screening among current smokers substantially contribute to many states' lower overall screening prevalence, particularly in Southern and Midwestern states where smoking prevalence is highest.
Abstract: Introduction To quantify the impact of current smokers' underutilization of colorectal cancer (CRC) and breast cancer screenings on overall cancer screening prevalence at the state level. Methods Behavioral Risk Factor Surveillance System 2010 data were used to calculate states' prevalence of screening for breast cancer and CRC overall and by current smoking status. To quantify the effect of underutilization of screening by current smokers on the overall breast cancer and CRC screening prevalence in each state, we derived a cancer screening underutilization (CSU) measure. Results CRC screening rates among adults aged 50 years and older ranged from 38.3% in Oklahoma to 59.5% in Rhode Island for current smokers and from 58.0% in Idaho to 75.9% in New Hampshire for nonsmokers. Mammography rates among women aged 40 years and older ranged from 26.8% in Utah to 63.6% in the District of Columbia for current smokers and from 50.8% in Utah to 73.0% in Massachusetts for nonsmokers. As a result, CSU values ranged from 2.1% to 6.7% for CRC screening and from 0.3% to 7.9% for mammography. Most states with the largest CSU values were located in the South or Midwest, whereas those with the smallest CSU values were located in the Northeast or West. Conclusions Lower levels of CRC and mammography screening among current smokers substantially contribute to many states' lower overall screening prevalence, particularly in Southern and Midwestern states where smoking prevalence is highest. These findings underscore the potential for more concentrated efforts to promote cessation and screening among smokers as a means to achieving cancer screening goals.

TL;DR: In this paper, the authors investigated whether expansion of Medicare reimbursement for colonoscopy screening in high-risk individuals has reduced the inappropriate use of surveillance in the Medicare population, and they used Kaplan-Meier analysis to estimate time to surveillance and polyp recurrence rates.
Abstract: textBackground: Surveillance in patients with previous polypectomy was underused in the Medicare population in 1994. This study investigates whether expansion of Medicare reimbursement for colonoscopy screening in high-risk individuals has reduced the inappropriate use of surveillance. Methods: We used Kaplan-Meier analysis to estimate time to surveillance and polyp recurrence rates for Medicare beneficiaries with a colonoscopy with polypectomy between 1998 and 2003 who were followed through 2008 for receipt of surveillance colonoscopy. Generalized Estimating Equations were used to estimate risk factors for: 1) failing to undergo surveillance and 2) polyp recurrence among these individuals. Analyses were stratified into three 2-year cohorts based on baseline colonoscopy date. Results: Medicare beneficiaries undergoing a colonoscopy with polypectomy in the 1998-1999 (n = 4,136), 2000-2001 (n = 3,538) and 2002-2003 (n = 4,655) cohorts had respective probabilities of 30%, 26% and 20% (p,<0.001) of subsequent surveillance events within 3 years. At the same time, 58%, 52% and 45% (p, <0.001) of beneficiaries received a surveillance event within 5 years. Polyp recurrence rates after 5 years were 36%, 30% and 26% (p, <0.001) respectively. Older age ( 70 years), female gender, later cohort (2000-2001 &2002-2003), and severe comorbidity were the most important risk factors for failure to undergo a surveillance event. Male gender and early cohort (1998-1999) were the most important risk factors for polyp recurrence. Conclusions: Expansion of Medicare reimbursement for colonoscopy screening in high-risk individuals has not reduced underutilization of surveillance in the Medicare population. It is important to take action now to improve this situation, because polyp recurrence is substantial in this population.

TL;DR: Foreign-born Asian breast cancer patients are less likely to receive BSC compared to US-born Whites or Asian-Americans, whereas foreign- Born Whites and foreign-born Blacks are more likely to receiving BCS than US- born Whites.
Abstract: Background: While effects of age, race, place of residence, and marital status on receipt of treatment among female breast cancer patients have been well documented, place of birth is a relatively less studied factor. The purpose of our study was to assess the relationship between birth place and type of surgery performed for early-stage breast cancer among US women of different racial and ethnic backgrounds. Methods: Eligible cases (n=119,560) were selected from the SEER registries for the period 2004–2009. US-born and foreign-born patients of different racial/ethnic groups were compared to US-born non-Hispanic Whites (NHW) with respect to receipt of breast conserving surgery (BCS) or mastectomy. Results of multivariable logistic regression analyses were expressed as adjusted odds ratios (OR) and the corresponding 95% confidence intervals (CI). Results: The proportion of BCS was highest in foreign-born Whites (62.5%) and lowest in foreign-born Asians (50.3%). Relative to US-born NHW, BCS was more common in foreign-born Whites (OR=1.21. 95% CI: 1.15–1.28) and foreign-born Blacks (OR=1.21. 95% CI: 1.15–1.28). In contrast, foreign-born Asians received less BCS compared to both US-born NHW (OR=.76, 95% CI: .72–.80) and US-born Asians (OR=.74, 95% CI: .64–.86). Conclusions: Foreign-born Asian breast cancer patients are less likely to receive BSC compared to US-born Whites or Asian-Americans, whereas foreign-born Whites and foreign-born Blacks are more likely to receive BCS than US-born Whites. Further studies are needed to understand cultural and or health systems factors that may explain these observations. (Ethn Dis. 2014;24[1]:110–115)

TL;DR: Whether differences exist in receipt of adjuvant therapy between uninsured and Medicaid patients in order to predict possible treatment patterns after the ACA takes effect is studied.
Abstract: 388 Background: Seminoma is the most common testicular cancer, and cancer specific survival approaches 100% if diagnosed and treated early. Following orchiectomy, several adjuvant therapy options exist for patients with stage 1A/B and 2A/B disease. As the Affordable Care Act’s (ACA) individual insurance mandate and expansion of Medicaid coverage will begin in 2014, we sought to understand whether differences exist in receipt of adjuvant therapy between uninsured and Medicaid patients in order to predict possible treatment patterns after the ACA takes effect. Methods: Uninsured and Medicaid patients diagnosed with seminoma from 1998-2010 in the National Cancer Data Base were identified. Multivariate logistic regressions were used to assess the relationship between uninsured status vs. Medicaid and receipt of adjuvant therapy. Results: Of 41,745 seminoma patients, 5,895 (14%) patients were on Medicaid or uninsured. Compared to Medicaid patients, uninsured patients were more likely to be younger (<29 years o...

TL;DR: Expansion of Medicare reimbursement for colonoscopy screening in high-risk individuals has not reduced underutilization of surveillance in the Medicare population, and action is needed to improve this situation.
Abstract: Background: Surveillance in patients with previous polypectomy was underused in the Medicare population in 1994. This study investigates whether expansion of Medicare reimbursement for colonoscopy screening in high-risk individuals has reduced the inappropriate use of surveillance. Methods: We used Kaplan-Meier analysis to estimate time to surveillance and polyp recurrence rates for Medicare beneficiaries with a colonoscopy with polypectomy between 1998 and 2003 who were followed through 2008 for receipt of surveillance colonoscopy. Generalized Estimating Equations were used to estimate risk factors for: 1) failing to undergo surveillance and 2) polyp recurrence among these individuals. Analyses were stratified into three 2-year cohorts based on baseline colonoscopy date. Results: Medicare beneficiaries undergoing a colonoscopy with polypectomy in the 1998- 1999 (n=4,136), 2000-2001 (n=3,538) and 2002-2003 (n=4,655) cohorts had respective probabilities of 30%, 26% and 20% (p<0.001) of subsequent surveillance events within 3 years. At the same time, 58%, 52% and 45% (p<0.001) of beneficiaries received a surveillance event within 5 years. Polyp recurrence rates after 5 years were 36%, 30% and 26% (p<0.001) respectively. Older age (≥ 70 years), female gender, later cohort (2000- 2001 & 2002-2003), and severe comorbidity were the most important risk factors for failure to undergo a surveillance event. Male gender and early cohort (1998-1999) were the most important risk factors for polyp recurrence. Conclusions: Expansion of Medicare reimbursement for colonoscopy screening in high- risk individuals has not reduced underutilization of surveillance in the Medicare population. It is important to take action now to improve this situation, because polyp recurrence is substantial in this population.
