Sun Exposure and Protection Behaviors among Long-term Melanoma Survivors and Population Controls.
Introduction: Melanoma is considered a generally preventable cancer, with excessive ultraviolet radiation (UVR) exposure being a strong causal factor. UVR exposure following a melanoma diagnosis can be modified to reduce risk of second primary melanomas. The goal of this study was to compare measures of UVR exposure and protection behaviors between long-term melanoma survivors and controls. ⋯ Conclusions: Although long-term melanoma survivors reported healthier UVR exposure and protection behaviors compared with controls, a sizeable proportion still reported elevated sun exposure, sunburns, and suboptimal UVR protection behaviors. Impact: Opportunities remain for improving sun protection to reduce future melanoma risk among melanoma survivors. Cancer Epidemiol Biomarkers Prev; 26(4); 607-13. ©2017 AACR.

EditorialMeasures Matter: The Local Exposure/Isolation (LEx/Is) Metrics and Relationships between Local-Level Segregation and Breast Cancer Survival.
Background: The Black-to-White disparity in breast cancer survival is increasing, and racial residential segregation is a potential driver for this trend. However, study findings have been mixed, and no study has comprehensively compared the effectiveness of different local-level segregation metrics in explaining cancer survival. Methods: We proposed a set of new local segregation metrics named local exposure and isolation (LEx/Is) and compared our new local isolation metric with two related metrics, the location quotient (LQ) and the index of concentration at extremes (ICE), across the 102 largest U. ⋯ Impact: We highlight how selection of a segregation measure can alter study findings. These relationships need to be validated in other geographic areas.

EditorialHousing Discrimination, Residential Racial Segregation, and Colorectal Cancer Survival in Southeastern Wisconsin.
Background: Residential racial segregation is still neglected in contemporary examinations of racial health disparities, including studies of cancer. Even fewer studies examine the processes by which segregation occurs, such as through housing discrimination. This study aims to examine relationships among housing discrimination, segregation, and colorectal cancer survival in southeastern Wisconsin. ⋯ These findings are in line with previous studies of breast cancer survival. Impact: Housing discrimination and institutional racism may be important targets for policy change to reduce health disparities, including cancer disparities.

Reallocating Time to Sleep, Sedentary Time, or Physical Activity: Associations with Waist Circumference and Body Mass Index in Breast Cancer Survivors.
Moderate-to-vigorous intensity physical activity (MVPA) is inversely associated with waist circumference and body mass index (BMI) among breast cancer survivors. Limited research has focused on behaviors that account for larger portions of the day [sleep, sedentary time, and light-intensity physical activity (LPA)]. We investigated the interdependent associations of self-reported sleep, objectively assessed prolonged and short bouts of sedentary time, total LPA, and total MVPA with waist circumference and BMI. ⋯ Increasing MVPA levels and decreasing time spent in prolonged, unbroken sedentary bouts may be avenues for improving body composition in this population.

Editorial Review Comparative StudyAssociation between Body Mass Index and Cancer Survival in a Pooled Analysis of 22 Clinical Trials.
Data are inconsistent on the association between body mass index (BMI) at time of cancer diagnosis and prognosis. We used data from 22 clinical treatment trials to examine the association between BMI and survival across multiple cancer types and stages. ⋯ Our findings suggest that disease, stage, and gender-specific body size recommendations for cancer survivors may be warranted.
