Post-treatment Neurocognition and Psychosocial Care Among Breast Cancer Survivors.

ABSTRACT: 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.

Project description:New findingsWhat is the central question of this study? Does the link between cardiorespiratory fitness and gut microbiota diversity persist after adjusting for the potential effects of percentage body fat and activity-related energy expenditure (AEE)? What is the main finding and its importance? This is the first study to examine the link between cardiorespiratory fitness and gut microbiota diversity while accounting for the underlying effects of percentage body fat and free-living AEE. Results from the present work suggest that cardiorespiratory fitness, not physical activity, is a superior correlate of gut microbiota diversity among post-primary treatment, non-metastatic breast cancer survivors.AbstractCancer treatment uniquely triggers multiple physiological shifts detrimental to overall health. Although previous research indicates a link between the gut microbiota and cardiorespiratory fitness, it is unclear whether these findings are attributable to potential underlying effects of percentage body fat or free-living activity energy expenditure (AEE). The microbe composition of faecal specimens from 37 breast cancer survivors was determined using 16S microbiome analyses. Individual-sample microbiota diversity (α-diversity) and between-sample community differences (β-diversity) were examined. Peak oxygen uptake ( V̇O2peak ) was estimated from a graded exercise test consistent with the modified Naughton protocol, in which exercise terminates at 85% of age-predicted maximal heart rate. The AEE was measured over 10 days using doubly labelled water, wherein the percentage body fat was calculated from total body water. Pearson correlations revealed α-diversity indices (Chao1, observed species, PD whole tree and Shannon) to be positively associated with V̇O2peak (r = 0.34-0.51; P < 0.05), whereas the percentage of maximal heart rate during stages 1-4 of the graded exercise test (r = -0.34 to -0.50; P < 0.05) and percentage body fat (r = -0.32 to -0.41; P < 0.05) were negatively associated with the same α-diversity indices. Multiple linear regression models showed that V̇O2peak accounted for 22 and 26% of the variance in taxonomic richness (observed species) and phylogenic diversity after adjustment for percentage body fat and menopausal status. Unweighted UniFrac (β-diversity) was significant for several outcomes involving cardiorespiratory fitness, and significant taxa comparisons were found. Associations between gut microbiota and free-living AEE were not found. Results from the present work suggest that cardiorespiratory fitness, not physical activity, is a superior correlate of gut microbiota diversity.
