Evaluating Psychological and Survival Outcomes of the Promoting Resilience in Stress Management for Metastatic Breast Cancer (PRISM-MBC) Intervention

Summary

This pilot interventional study evaluates the change from baseline to post-intervention in resilience and other patient-reported outcomes for individuals with a recent diagnosis of metastatic breast cancer (MBC) participating in the Promoting Resilience in Women with Breast Cancer (PRISM) intervention, overall and stratified by race, and to evaluate the feasibility and acceptability of the PRISM intervention in the MBC population. Black women with MBC have shorter survival from the time of metastatic diagnosis to death, compared to White women with clinically similar disease, and may have more rapid declines in quality of life over time. Adverse social determinants of health may play a role in these outcome disparities, due to both social barriers in accessing care, and through direct stress-mediated biological effects on the host and tumor microenvironment. Interventions to reduce stress and optimize resilience during treatment of MBC may improve quality of life and even improve disease outcomes; however, feasibility of face-to-face intervention during intensive medical treatment is limited. Thus, this study aims to demonstrate the feasibility of a remotely delivered resilience intervention, PRISM, already proven effective in other cancer settings, for MBC patients, and to gather preliminary efficacy data for a future randomized trial.
