Abstract/Description: The purpose of this study was to compare body composition, bone mineral density (BMD), strength, muscle power, and quality of life in short-term breast cancer survivors (ST-BCS) and long-term breast cancer survivors (LT-BCS). METHODS: Body composition and BMD measures were completed on 17 ST-BCS (57.2  9.3 years) and 26 LT-BCS (62.0  7.2 years) via dual energy X-ray absorptiometry (DXA). Upper body strength was measured by a 1 repetition maximum chest press and lower body strength was assessed using BIODEX isokinetic and isometric leg extension and flexion tests. Muscle power was measured by a Tendo unit and quality of life was assessed by the SF-36 questionnaire. RESULTS: Mean time since completion of primary treatment was 7.7  7.1 years. Time since treatment completion for ST-BCS and LT-BCS was 1.8  1.1 years and 11.5  6.7 years, respectively. No significant differences were found between ST-BCS and LT-BCS in measures of body composition, BMD, strength, muscle power, or quality of life. A positive correlation was observed between time since completion of treatment and lumbar spine BMD (r=.38). CONCLUSION: Our findings show that ST-BCS and LT-BCS experience similar rates of changes in body composition, BMD, strength, power, and quality of life, regardless of time since the completion of treatment. This may be due to the similarity in menopausal age between the ST-BCS and LT-BCS in this study. Both may have experienced the same rate of age-related changes since the onset of menopause, as well as similar changes during the cancer treatment period. More research is needed to determine what factors influenced the changes specifically in the lumbar spine BMD over time. Furthermore, more research is needed comparing ST-BCS and LT-BCS to determine whether the effects of treatment persist over time and for how long.
