Study design and cohort characteristics of the Childhood Cancer Survivor Study: a multi-institutional collaborative project.

Abstract: Background Increased attention has been directed toward the long-term health outcomes of survivors of childhood cancer. To facilitate such research, a multi-institutional consortium established the Childhood Cancer Survivor Study (CCSS), a large, diverse, and well-characterized cohort of 5-year survivors of childhood and adolescent cancer. Procedure Eligibility for the CCSS cohort included a selected group of cancer diagnoses prior to age 21 years between 1970–1986 and survival for at least 5 years. Results A total of 20,276 eligible subjects were identified from the 25 contributing institutions, of whom 15% are considered lost to follow-up. Currently, 14,054 subjects (69.3% of the eligible cohort) have participated by completing a 24-page baseline questionnaire. The distribution of first diagnoses includes leukemia (33%), lymphoma (21%), neuroblastoma (7%), CNS tumor (13%), bone tumor (8%), kidney tumor (9%), and soft-tissue sarcoma (9%). Abstraction of medical records for chemotherapy, radiation therapy, and surgical procedures has been successfully completed for 98% of study participants. Overall, 78% received radiotherapy and 73% chemotherapy. Conclusion The CCSS represents the largest and most extensively characterized cohort of childhood and adolescent cancer survivors in North America. It serves as a resource for addressing important issues such as risk of second malignancies, endocrine and reproductive outcome, cardiopulmonary complications, and psychosocial implications, among this unique and ever-growing population.

Twenty years of follow-up among survivors of childhood and young adult acute myeloid leukemia: a report from the Childhood Cancer Survivor Study.

Abstract: BACKGROUND Limited data exist on the comprehensive assessment of late medical and social effects experienced by survivors of childhood and young adult acute myeloid leukemia (AML). METHODS This analysis included 272 5-year AML survivors who participated in the Childhood Cancer Survivor Study (CCSS). All patients were diagnosed at age ≤21 years between the years 1970 and 1986, and none underwent stem cell transplantation. Rates of survival, relapse, and late outcomes were analyzed. RESULTS The average follow-up was 20.5 years (range, 5–33 years). The overall survival rate was 97% at 10 years (95% confidence interval [95%CI], 94%–98%) and 94% at 20 years (95% CI, 90%–96%). Six survivors reported 8 recurrences. The cumulative incidence of recurrent AML was 6.6% at 10 years (95% CI, 3.7%–9.6%) and 8.6% at 20 years (95% CI, 5.1%–12.1%). Ten subsequent malignant neoplasms (SMN) were reported, including 4 with a history of radiation therapy, for a 20-year cumulative incidence of 1.7% (95% CI, 0.02%–3.4%). Six cardiac events were reported, for a 20-year cumulative incidence 4.7% (95% CI, 2.1%–7.3%). Half of the survivors reported a chronic medical condition and, compared with siblings, were at increased risk for severe or life-threatening chronic medical conditions (16% vs 5.8%; P < .001). Among those aged ≥25 years, the age-adjusted marriage rates were similar among survivors and the general United States population (57% for both) and lower compared with siblings (67%; P < .01). Survivors' college graduation rates were lower compared with siblings but higher than the general population (40% vs 52% vs 34%, respectively; P < .01). Employment rates were similar between survivors, siblings, and the general population (93%, 97.6%, and 95.8%, respectively). CONCLUSIONS Long-term survival from childhood AML ≥5-years after diagnosis was favorable. Late-occurring medical events remained a concern with socioeconomic achievement lower than expected within the individual family unit, although it was not different from the general United States population.

Chronic Health Conditions in Adult Survivors of Childhood Cancer

Abstract: Background Only a few small studies have assessed the long-term morbidity that follows the treatment of childhood cancer. We determined the incidence and severity of chronic health conditions in adult survivors. Methods The Childhood Cancer Survivor Study is a retrospective cohort study that tracks the health status of adults who received a diagnosis of childhood cancer between 1970 and 1986 and compares the results with those of siblings. We calculated the frequencies of chronic conditions in 10,397 survivors and 3034 siblings. A severity score (grades 1 through 4, ranging from mild to life-threatening or disabling) was assigned to each condition. Cox proportional-hazards models were used to estimate hazard ratios, reported as relative risks and 95% confidence intervals (CIs), for a chronic condition. Results Survivors and siblings had mean ages of 26.6 years (range, 18.0 to 48.0) and 29.2 years (range, 18.0 to 56.0), respectively, at the time of the study. Among 10,397 survivors, 62.3% had at least one chronic condition; 27.5% had a severe or life-threatening condition (grade 3 or 4). The adjusted relative risk of a chronic condition in a survivor, as compared with siblings, was 3.3 (95% CI, 3.0 to 3.5); for a severe or life-threatening condition, the risk was 8.2 (95% CI, 6.9 to 9.7). Among survivors, the cumulative incidence of a chronic health condition reached 73.4% (95% CI, 69.0 to 77.9) 30 years after the cancer diagnosis, with a cumulative incidence of 42.4% (95% CI, 33.7 to 51.2) for severe, disabling, or life-threatening conditions or death due to a chronic condition. Conclusions Survivors of childhood cancer have a high rate of illness owing to chronic health conditions.

Childhood and adolescent cancer statistics, 2014

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.

Cardiac outcomes in a cohort of adult survivors of childhood and adolescent cancer: retrospective analysis of the Childhood Cancer Survivor Study cohort.

Abstract: Objectives To assess the incidence of and risks for congestive heart failure, myocardial infarction, pericardial disease, and valvular abnormalities among adult survivors of childhood and adolescent cancers. Design Retrospective cohort study. Setting 26 institutions that participated in the Childhood Cancer Survivor Study. Participants 14 358 five year survivors of cancer diagnosed under the age of 21 with leukaemia, brain cancer, Hodgkin’s lymphoma, non-Hodgkin’s lymphoma, kidney cancer, neuroblastoma, soft tissue sarcoma, or bone cancer between 1970 and 1986. Comparison group included 3899 siblings of cancer survivors. Main outcome measures Participants or their parents (in participants aged less than 18 years) completed a questionnaire collecting information on demographic characteristics, height, weight, health habits, medical conditions, and surgical procedures occurring since diagnosis. The main outcome measures were the incidence of and risk factors for congestive heart failure, myocardial infarction, pericardial disease, and valvular abnormalities in survivors of cancer compared with siblings. Results Survivors of cancer were significantly more likely than siblings to report congestive heart failure (hazard ratio (HR) 5.9, 95% confidence interval 3.4 to 9.6; P Conclusion Survivors of childhood and adolescent cancer are at substantial risk for cardiovascular disease. Healthcare professionals must be aware of these risks when caring for this growing population.

Health Status of Adult Long-term Survivors of Childhood Cancer A Report From the Childhood Cancer Survivor Study

Abstract: ContextAdult survivors of childhood cancer are at risk for medical and psychosocial sequelae that may adversely affect their health status.ObjectivesTo compare the health status of adult survivors of childhood cancer and siblings and to identify factors associated with adverse outcomes.Design, Setting, and ParticipantsHealth status was assessed in 9535 adult participants of the Childhood Cancer Survivor Study, a cohort of long-term survivors of childhood cancer who were diagnosed between 1970 and 1986. A randomly selected cohort of the survivors' siblings (n = 2916) served as a comparison group.Main Outcome MeasuresSix health status domains were assessed: general health, mental health, functional status, activity limitations, cancer-related pain, and cancer-related anxiety/fears. The first 4 domains were assessed in the control group.ResultsSurvivors were significantly more likely to report adverse general health (odds ratio [OR], 2.5; 95% confidence interval [CI], 2.1-3.0; P<.001), mental health (OR, 1.8; 95% CI, 1.6-2.1; P<.001), activity limitations (OR, 2.7; 95% CI, 2.3-3.3; P<.001), and functional impairment (OR, 5.2; 95% CI, 4.1-6.6; P<.001), compared with siblings. Forty-four percent of survivors reported at least 1 adversely affected health status domain. Sociodemographic factors associated with reporting at least 1 adverse health status domain included being female (OR, 1.4; 95% CI, 1.3-1.6; P<.001), lower level of educational attainment (OR, 2.0; 95% CI, 1.8-2.2; P<.001), and annual income less than $20 000 (OR, 1.8; 95% CI, 1.6-2.1; P<.001). Relative to those survivors with childhood leukemia, an increased risk was observed for at least 1 adverse health status domain among those with bone tumors (OR, 2.1; 95% CI, 1.8-2.5; P<.001), central nervous system tumors (OR, 1.7; 95% CI, 1.5-2.0; P<.001), and sarcomas (OR, 1.2; 95% CI, 1.1-1.5; P = .01).ConclusionClinicians caring for adult survivors of childhood cancer should be aware of the substantial risk for adverse health status, especially among females, those with low educational attainment, and those with low household incomes.

Late Mortality Among 5-Year Survivors of Childhood Cancer: A Summary From the Childhood Cancer Survivor Study

Abstract: The Childhood Cancer Survivor Study (CCSS) has assembled the largest cohort to date for assessment of late mortality. Vital status and cause of death of all patients eligible for participation in CCSS was determined using the National Death Index and death certificates to characterize the mortality experience of 20,483 survivors, representing 337,334 person-years of observation. A total of 2,821 deaths have occurred as of December 31, 2002. The overall cumulative mortality is 18.1% (95% CI, 17.3 to 18.9) at 30 years from diagnosis. With time, while all-cause mortality rates have been stable, the pattern of late death is changing. Mortality attributable to recurrence or progression of primary disease is decreasing, with increases in rates of mortality attributable to subsequent neoplasms (standardized mortality ratios [SMR], 15.2; 95% CI, 13.9 to 16.6), cardiac death (SMR, 7.0; 95% CI, 5.9 to 8.2), and pulmonary death (SMR, 8.8; 95% CI, 6.8 to 11.2) largely due to treatment-related causes. In addition, the CCSS has identified specific treatment-related risk factors for late mortality. Radiotherapy (relative risk [RR], 2.9; 95% CI, 2.1 to 4.2), alkylating agents (RR, 2.2; 95% CI, 1.6 to 3.0), and epipodophyllotoxins (RR, 2.3; 95% CI, 1.2 to 4.5) increase the risk of death due to subsequent malignancy. Cardiac radiation exposure (RR, 3.3; 95% CI, 2.0 to 5.5) and high dose of anthracycline exposure (RR, 3.1; 95% CI, 1.6 to 5.8) are associated with late cardiac death. By continued longitudinal follow-up of the cohort and expansion of the cohort to include patients diagnosed between 1987 and 1999, the CCSS will remain a primary resource for assessment of late mortality of survivors of childhood cancers.
