A Prospective Assessment of Loss of Grip Strength by Baseline BMI in Breast Cancer Patients Receiving Adjuvant Aromatase Inhibitors and Tamoxifen

Universitaire Ziekenhuizen KU Leuven296 enrolled

Overview

The Logribmet study is a prospective study that evaluate grip strength changes in both hands of postmenopausal women with breast cancer receiving treatment with tamoxifen or an aromatase inhibitor. Patients included in the study will undergo a grip strength measurement and receive a rheumatological questionnaire prior to the start of treatment, then at 3 and 6 months and at year 1 into therapy. Furthermore, BMI will be measured to assess if BMI is a predictor for the decrease in grip strength. IGF-I, GH and IGFBP-3 serum levels will also be measured at all time points.
