Blood-based biomarkers of frailty in solid tumors: a systematic review.

This review examines the current literature to identify biomarkers of frailty across patients with solid tumors. We conducted the systematic review using preferred reporting items for systematic reviews and meta-analysis guidelines (PRISMA). PubMed, Web of Science, and Embase databases were searched from their inception to December 08, 2021, for reports of biomarkers and frailty. Two reviewers independently screened titles, abstracts, and full-text articles. A quality assessment was conducted using NHLBI Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies, and Quality Assessment of Case-Control Studies. In total, 915 reports were screened, and 14 full-text articles were included in the review. Most studies included breast tumors, were cross-sectional in design, and measured biomarkers at baseline or pre-treatment. Frailty tools varied with Fried Frailty Phenotype and the geriatric assessment most frequently used. Increased inflammatory parameters (i.e., Interleukin-6, Neutrophil Lymphocyte Ratio, Glasgow Prognostic Score-2) were associated with frailty severity. Only six studies were rated as good quality using assessment ratings. Together, the small number of studies and heterogeneity in frailty assessment limited our ability to draw conclusions from the extant literature. Future research is needed to identify potential target biomarkers of frailty in cancer survivors that may aid in early detection and referral.

A systematic review of dyadic studies examining depression in couples facing breast cancer.

Problem identification: The aim was to synthesize the dyadic literature on depression among couples in which one person has breast cancer.Literature search: A database search (PubMed, PsychInfo, CINAHL) was conducted to synthesize the literature. Studies' methodological quality was evaluated, and correlates of depression/interdependence were abstracted.Data evaluation/synthesis: Ten (of 270) studies met the inclusion criteria and were of satisfactory methodological quality. Depression is prevalent in both patients and partners, and was correlated with many psychosocial variables including sexual satisfaction, relationship quality, social support, and appraisal of health. Depression in one member of the dyad predicted depression in their companion.Conclusions: Levels of relationship quality, sexual satisfaction, and support felt by couples facing breast cancer may be predictive of depression in each individual. The depressive state of one partner appears to influence the other. More research is needed to support dyadic strategies for mitigating depression in couples facing breast cancer.
