Self-reported comorbid conditions and medication usage in breast cancer survivors with and without lymphedema.

PURPOSE/OBJECTIVES To compare the self-reported comorbid conditions and medication usage between breast cancer survivors with and without breast cancer treatment-related lymphedema. DESIGN Descriptive, cross-sectional. SETTING A community-based study conducted in a major metropolitan area and surrounding rural counties in the southeastern United States. SAMPLE A convenience sample of 64 breast cancer survivors with lymphedema and 64 breast cancer survivors without lymphedema who were age matched within three years and recruited for a parent study. Twenty-one additional non-age-matched breast cancer survivors with or without lymphedema also were included. METHODS Self-reported survey instruments and height and weight measurement. MAIN RESEARCH VARIABLES Lymphedema, demographic information, self-reported comorbid diseases or medical issues, and medication usage. FINDINGS Breast cancer survivors with lymphedema experienced more comorbid conditions. Statistically significant group differences were found in body mass index, orthopedic issues, cardiac medications, hormone blockers, and osteoporosis medication or calcium supplement usage. Co-occurrence of diabetes and carpal tunnel syndrome approached statistical significance. Breast cancer survivors with lymphedema were older and had lower incomes. CONCLUSIONS Comorbid conditions may influence the development of breast cancer treatment-related lymphedema. Further research, particularly a longitudinal study, is indicated. IMPLICATIONS FOR NURSING Healthcare professionals who care for breast cancer survivors need to routinely assess them for the presence of comorbid conditions and the development of lymphedema. Obese breast cancer survivors may benefit from weight reduction interventions to possibly decrease their risk of developing lymphedema and improve their overall health status. Patients with arthritis and orthopedic and cardiac issues such as hypertension may warrant careful monitoring.
