Literature suggests Oncology Massage (OM) reduces anxiety. However, research is limited in large, diverse, nonexperimentally manipulated outpatient samples of cancer patients. The purpose of this study was to 1) describe OM visit patterns, 2) describe anxiety response to OM, and 3) determine if OM resulted in significantly reduced anxiety at first visit, across all visits, and longitudinally over time controlling for demographic factors. From January 2015-June 2019, a cohesive, consecutive, retrospective sample evaluated their anxiety before and
12052 Background: Low muscle mass (skeletal muscle index, SMI) and density (skeletal muscle density, SMD) are associated with chemotherapy toxicity and shorter survival in women with breast cancer. This has not been studied specifically in women ≤ 40 years at diagnosis. They have different body compositions and more aggressive cancers than older women. We compared pre-treatment muscle measures in survivors and non-survivors and investigated their association with overall survival (OS) and progression-free survival (PFS). Methods: This case-control study included 112 women aged ≤ 40 years at diagnosis. Women with pre-treatment CT scans from 2009-2018 were identified; non-survivors were matched with survivors by age, year of diagnosis and disease characteristics. Body composition was determined by CT analysis. Measures were compared between the groups using Kruskal-Wallis tests. Kaplan-Meier methods summarized OS and PFS and the associations of muscle characteristics with OS and PFS were examined by univariate Cox proportional hazard models. Results: Median age was 35 years; median follow-up was 8.2 years. 75% had Stage II or III disease and 21% Stage IV disease. 33% were sarcopenic (SMI < 40) and 16% had low SMD (HU <37.8). Non-survivors had more intermuscular fat (IMAT), reduced SMD, and reduced skeletal muscle gauge (SMG). Sarcopenia was not associated with OS; however, sarcopenia was associated with shorter PFS. The median skeletal muscle gauge was 1973; low skeletal muscle gauge (SMG <1973) was associated with both shorter OS and PFS. Median IMAT was 1.6, and high IMAT (≥1.6) was associated with shorter OS and PFS. Conclusions: Low muscle mass (sarcopenia) at breast cancer diagnosis was associated with shorter PFS and low muscle density (low SMG and higher IMAT) was associated with shorter OS and PFS in women ≤ 40 years. These sub-optimal muscle characteristics may indicate an overall reduced state of health and/or decreased ability to tolerate treatment, thus reducing survival. Future research should determine the significance of muscle changes throughout treatment and establish standards for improved muscle health.[Table: see text]
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
