Background: Vitamin D deficiency (\< 10 ng/mL) and insufficiency (10-30 ng/mL) may contribute to musculoskeletal symptoms observed in patients taking letrozole. This study was undertaken to assess the vitamin D status in breast cancer patients who received letrozole for \> 6 months and to evaluate the effects of vitamin D3 and calcium supplementation on them.
Methods: Forty breast cancer patients were included. They were divided into 2 equal groups: Control group received Letrozole only, and VitD/Ca group received Letrozole in addition to 2000 IU vitamin D3 and 1000 mg of calcium per day for 12 weeks. Baseline serum 25-hydroxy vitamin D concentrations were assayed and standard health assessment questionnaire was completed to assess the disability caused by musculoskeletal symptoms.
