OBJECTIVES: Cancer continues to be the leading disease-related cause of death among children and adolescents in the United States. More current information is needed to describe recent cancer trends and identify demographic and geographic variations. METHODS: We analyzed data from the National Program of Cancer Registries and Surveillance, Epidemiology, and End Results statewide registries representing 94.2% of the US population to identify cancers diagnosed among persons aged 0 to 19 years during 2001–2009. Age-adjusted rates and annual percentage change for trends were calculated. Data were stratified by age, gender, race, ethnicity, and geography. RESULTS: We identified 120 137 childhood and adolescent cancer cases during 2001–2009 with an age-adjusted incidence rate of 171.01 per million. The overall rate of all cancers combined remained stable over time (annual percent change [APC], 0.3%; 95% confidence interval [CI], −0.1 to 0.7). There was an increase in the overall cancer trend among African American children and adolescents (APC, 1.3%; 95% CI, 0.2 to 2.5). An increasing trend for thyroid cancer was observed among both genders (APC, 4.9%; 95% CI, 3.2 to 6.6) and specifically among adolescents and those in the Northeast, South, and West regions of the United States. Renal carcinoma incidence was increasing significantly overall (APC, 5.4%; 95% CI, 2.8 to 8.1). Extracranial and extragonadal germ cell tumors and melanoma were both significantly decreasing. CONCLUSIONS: This study reports the novel finding that renal carcinoma rates are increasing among children and adolescents. This study confirms that thyroid cancer rates are increasing and further describes rising cancer rates among African Americans.

CONTEXT: Adverse childhood experiences (ACEs) can affect health and well-being across the life course. OBJECTIVE: This systematic review summarizes the literature on associations between ACEs and risk of cancer in adulthood. DATA SOURCES: We searched PubMed to identify relevant publications published on or before May 31, 2015. STUDY SELECTION: We included original research quantifying the association between ACEs and adult cancer incidence. Case reports and reviews were excluded. DATA ABSTRACTION: Two reviewers independently abstracted and summarized key information (eg, ACE type, cancer type, risk estimates) from included studies and resolved all discrepancies. RESULTS: Twelve studies were included in the review. In studies in which ACE summary scores were calculated, significant associations were observed between the scores and an increased risk of cancer in adulthood. Of the different types of ACEs examined, physical and psychological abuse victimization were associated with risk of any cancer in 3 and 2 studies, respectively. Two studies also reported significant associations with regard to sexual abuse victimization (1 for cervical cancer and 1 for any cancer). However, 2 other studies reported no significant associations between childhood sexual or physical abuse and incidence of cervical or breast cancer. LIMITATIONS: Because of heterogeneity across studies, we were unable to compute a summary effect estimate. CONCLUSIONS: These findings suggest that childhood adversity in various forms may increase a person’s cancer risk. Further research is needed to understand the mechanisms driving this relationship and to identify opportunities to prevent and mitigate the deleterious effects of early adversity on long-term health.

Psychosocial barriers and facilitators to clinical trial enrollment and adherence for adolescents with cancer.

Natasha Buchanan; Rebecca Block; Ashley Wilder Smith; Eric Tai

Adolescents (aged 15–19 years) have not experienced the same survival gains as children and older adults diagnosed with cancer. Poor clinical trial enrollment and adherence rates among adolescents may account for some of this disparity. Although biological, regulatory, systemic, and practice-related challenges to clinical trial enrollment and adherence have been examined, studies of psychosocial factors, which can serve as barriers or facilitators to enrollment and adherence, are limited. To bring attention to these psychological factors, we reviewed existing literature on psychosocial barriers and facilitators that can affect an adolescent’s decision to enroll and adhere to a clinical trial. We also provide potential strategies to address psychosocial factors affecting clinical trial accrual and adherence.

Dissemination and Translation: A Frontier for Cancer Survivorship Research

Lori A. Pollack; Nikki A. Hawkins; Brandy L. Peaker; Natasha Buchanan; Betsy Risendal

As the field of survivorship research grows, the need for translation is imperative to expand new knowledge into arenas that directly impact survivors. This commentary seeks to encourage research focused on dissemination and translation of survivorship interventions and programs, including practice-based research. We overview diffusion, dissemination and translation in the context of cancer survivorship and present the RE-AIM and Knowledge to Action frameworks as approaches that can be used to expand research into communities. Many academic, governmental, and community-based organizations focus on cancer survivor. Future survivorship research should contribute to harmonizing these assets to identify effective interventions, maximize their reach and adoption, and integrate promising practices into routine care.

INTRODUCTION Chemotherapy for breast cancer has been associated with cognitive problems; however, the impact of adjuvant hormone therapy is less clear. No studies have explored provider discussions about cognitive concerns or factors associated with neurocognitive treatment. This study examined cognitive problems, factors associated with having a provider discussion, and receipt of neurocognitive treatment. METHODS Female breast cancer survivors (N=2,537) from the Sister Study and the Two Sister Study who were at least 1 year post-treatment were surveyed in 2012 about their cancer therapies (confirmed by medical records); cognitive concerns; related provider discussions; and neurocognitive treatment. A total of 2,296 women were included in the current 2014 analysis. Extensive covariate information was also ascertained for predictive multivariate models. RESULTS The prevalence of self-reported cognitive problems after treatment was 60%. Of those reporting cognitive problems, only 37% had discussed those concerns with a provider and 15% had been treated for cognitive symptoms. The odds of reported cognitive concerns that started during and after treatment were elevated for those who received only hormone therapy and no chemotherapy (OR=1.64, 95% CI=1.15, 2.33); chemotherapy and no hormone therapy (OR=5.63, 95% CI=3.52, 9.00); or both (OR=6.33, 95% CI=4.21, 9.54) compared with those reporting neither treatment. CONCLUSIONS The high prevalence of cognitive concerns underscores the importance of monitoring breast cancer survivors for potential neurocognitive effects of hormone and chemotherapy, discussions with survivors about those concerns, and treatment referrals. Monitoring changes over time can help to evaluate both psychosocial and neurocognitive care provided for survivors.

Understanding and Addressing the Lack of Clinical Trial Enrollment Among Adolescents With Cancer

Eric Tai; Natasha Buchanan; Dena Eliman; Lauren Westervelt; Lynda Kwon Beaupin; Silvana Lawvere; Archie Bleyer

Despite overall improvement in survival, morbidity, and quality of life of US patients with cancer, this progress is less prevalent in the population of adolescent and young adult patients with cancer, including those between the ages of 15 and 19 years. Evidence suggests that participation in clinical trials is associated with better survival outcomes among children and adolescents with cancer; however, adolescents have lower clinical trial participation rates compared with younger age cohorts. To better understand the unique concerns among adolescent patients with cancer, the Division of Cancer Prevention and Control at the Centers for Disease Control and Prevention convened a workgroup of researchers and health care providers in the field of adolescent and young adult oncology and cancer survivorship to examine the barriers and challenges limiting the participation of adolescents in clinical trials and to define ways to improve upon these concerns. This article summarizes the activities of the workgroup and their suggestions for enhanced accrual.

Treatment Setting, Clinical Trial Enrollment, and Subsequent Outcomes Among Adolescents With Cancer: A Literature Review

Eric Tai; Natasha Buchanan; Lauren Westervelt; Dena Elimam; Silvana Lawvere

BACKGROUND: There has been an overall improvement in survival rates for persons with cancer over the past 35 years. However, these gains are less prevalent among adolescents with cancer aged 15 to 19 years, which may be due to lower clinical trial enrollment among adolescents with cancer. METHODS: We conducted a literature review to assess current research regarding clinical trial enrollment and subsequent outcomes among adolescents with cancer. The search included English-language publications that reported original data from January 1985 to October 2011. RESULTS: The search identified 539 records. Of these 539 records, there were 30 relevant original research articles. Multiple studies reported that adolescents with cancer are enrolled in clinical trials at lower rates compared with younger children and older adults. Treatment setting, physician type, and institution type may all be factors in the low enrollment rate among adolescents. Few data focused solely on adolescents, with many studies combining adolescents with young adults. The number of available studies related to this topic was limited, with significant variability in study design, methods, and outcomes. CONCLUSIONS: This literature review suggests that adolescents with cancer are not treated at optimal settings and are enrolled in clinical trials at low rates. This may lead to inferior treatment and poor subsequent medical and psychosocial outcomes. The scarcity in data further validates the need for additional research focusing on this population.

Background. Differences in healthcare and cancer treatment for cancer survivors in the United States (US) have not been routinely examined in nationally representative samples or studied before and after important Institute of Medicine (IOM) recommendations calling for higher quality care provision and attention to comprehensive cancer care for cancer survivors. Methods. To assess differences between survivor characteristics in 1992 and 2010, we conducted descriptive analyses of 1992 and 2010 National Health Interview Survey (NHIS) data. Our study sample consisted of 1018 self-reported cancer survivors from the 1992 NHIS and 1718 self-reported cancer survivors from the 2010 NHIS who completed the Cancer Control (CCS) and Cancer Epidemiology (CES) Supplements. Results. The prevalence of reported survivors increased from 1992 to 2010 (4.2% versus 6.3%). From 1992 to 2010, there was an increase in long-term cancer survivors and a drop in multiple malignancies, and surgery remained the most widely used treatment. Significantly fewer survivors (<10 years after diagnosis) were denied insurance coverage. Survivors continue to report low participation in counseling or support groups. Conclusions. As the prevalence of cancer survivors continues to grow, monitoring differences in survivor characteristics can be useful in evaluating the effects of policy recommendations and the quality of clinical care.

OBJECTIVES To provide a population-based description of the anatomic distribution of melanoma among non-Hispanic black patients and to explore how characteristics of this distribution relate to the etiologies previously reported for both white and black patients. DESIGN Cross-sectional, retrospective. SETTING United States, January 1, 1998, through December 31, 2007. PATIENTS A total of 1439 non-Hispanic black patients with a diagnosis of malignant melanoma. MAIN OUTCOME MEASURES Proportion of melanoma found per anatomic site (head, face, or neck; trunk; upper limb and shoulder; and the lower limb and hip) by patient sex, age, and region of diagnosis. RESULTS The most frequent site of melanoma was the lower limb and hip (848 [58.9%]) and trunk (238 [16.5%]). The youngest median age was presented for diagnoses of the trunk (male: 56 years and females: 48 years). Presentation on the lower limb and hip accounted for most diagnoses in both the northern and southern geographic regions (north: 58.2% and south: 59.7%). CONCLUSIONS By increasing knowledge about the burden of this disease within the black population, our findings can be used to improve the early detection of melanoma by both the patient and the provider.
