Key Points
Geriatric assessment, with a focus on cognitive and physical function, improves prediction of survival among older adults treated for AML. Use of geriatric assessment may inform trial design and interventions to improve outcomes for older adults with AML.
To reduce the incidence of invasive cervical cancer among women with access to screening and treatment, Pap screening adherence should be increased. In addition, strategies to improve the accuracy of Pap screening could afford earlier detection of cervical cancer.
Objective-To evaluate the effectiveness of methods that control for confounding by indication, we compared breast cancer recurrence rates among women receiving adjuvant chemotherapy versus those who did not.Study Design and Setting-In a medical record review-based study of breast cancer treatment in older women (n=1798) diagnosed 1990-1994, our crude analysis suggested adjuvant Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication.

Conclusion-Conventional methods do not control for unmeasured factors, which often remain important when addressing confounding by indication. PS and IV analysis methods can be useful under specific situations, but neither method adequately controlled confounding by indication in this study.

Attention to nonadherence among older women at risk of discontinuation, particularly those receiving BCS without radiotherapy, might improve breast cancer outcomes for these women.
BACKGROUND:With prior reports indicating a lack of progress in survival improvement in older adolescents and young adults (AYAs) aged 15 to 39 years with cancer compared with both younger and older patients with cancer, the current analysis provides an update of survival trends of cancers among AYAs, children, and older adults. METHODS: Data from the National Cancer Institute Surveillance, Epidemiology, and End Results database for 13 regions were used to ascertain survival trends of the 34 most frequent cancers diagnosed in AYAs compared with children and older adults. RESULTS: As of 2002 through 2006, the 5-year relative survival rate for all invasive cancers in AYAs was 82.5% (standard error, 0.2%). In AYAs, 14 cancers demonstrated evidence of a statistically significant improvement in their 5-year relative survival since 1992. Survival improved less in AYAs than in children for acute myeloid leukemia and medulloblastoma. Fourteen cancers had survival improvements that were found to be less in AYAs compared with older adults, including hepatic carcinoma, acute myeloid leukemia, high-grade astrocytoma, acute lymphocytic leukemia, pancreatic carcinoma, low-grade astrocytoma, gastric carcinoma, renal carcinoma, cancer of the oral cavity and pharynx, Hodgkin lymphoma, ovarian cancer, fibromatous sarcoma, other soft tissue sarcoma, and thyroid carcinoma. CONCLUSIONS: Improvements in the survival of several cancer types that occur frequently in AYAs are encouraging. However, survival does not appear to be improving to the same extent in AYAs as in children or older adults for several cancers. Further investment in exploring the distinct biology of tumors in this age group, and of their hosts, must be a priority in AYA oncology.
The contribution of specific cancer therapies, comorbid medical conditions, and host factors to mortality risk after pediatric Hodgkin lymphoma (HL) is unclear. We assessed leading morbidities, overall and cause-specific mortality, and mortality risks among 2742 survivors of HL in the Childhood Cancer Survivor Study, a multi-institutional retrospective cohort study of survivors diagnosed from 1970 to 1986. Excess absolute risk for leading causes of death and cumulative incidence and standardized incidence ratios of key medical morbidities were calculated. Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of risks for overall and cause-specific mortality. Substantial excess absolute risk of mortality per 10 000 person-years was identified: overall 95.5; death due to HL 38.3, second malignant neoplasms 23.9, and cardiovascular disease 13.1. Risks for overall mortality included radiation dose > 3000 rad (
Background
While rural residents are more likely to be diagnosed with more advanced cancers and die of cancer, little is known about rural-urban disparities in self-reported health among survivors.
Methods
We identified adults with a self-reported cancer history from the National Health Interview Survey (2006–2010). Rural-urban residence was defined using US census definitions. Logistic regression with weighting to account for complex sampling was used to assess rural-urban differences in health status after accounting for differences in demographic characteristics.
Results
Of the 7,804 identified cancer survivors, 20.8% were rural residents. This translates to a population of 2.8 million rural cancer survivors in the US. Rural survivors were more likely than urban survivors to be non-Hispanic white (p<.001), have less education (p<.001) and lack health insurance (p<.001). Rural survivors reported worse health in all domains. After adjustment for sex, race/ethnicity, age, marital status, education, insurance, time since diagnosis, and number of cancers, rural survivors were more likely to report fair/poor health [OR=1.39, 95%CI=1.20–1.62, psychological distress [OR=1.23, 1.00–1.50], ≥2 non-cancer comorbidities [OR=1.15, 1.01–1.32], and health-related unemployment [OR=1.66, 1.35–2.03].
Conclusions
We provide the first estimate of the proportion and number of US adult cancer survivors who reside in rural areas. Rural cancer survivors are at greater risk for a variety of poor health outcomes, even many years after their cancer diagnosis, and should be a target for interventions to improve their health and well-being.
