| Skeletal muscle and adipose tissue express the vitamin D receptor and may be a mechanism through which vitamin D supplementation slows cancer progression and reduces cancer death. In this exploratory analysis of a double-blind, multicenter, randomized phase II clinical trial, 105 patients with advanced or metastatic colorectal cancer who were receiving chemotherapy were randomized to either high-dose vitamin D3 (4000 IU) or standard-dose (400 IU) vitamin D3 . Body composition was measured with abdominal computed tomography at enrollment (baseline) and after cycle 8 of chemotherapy (16 weeks). As compared with standard-dose vitamin D3 , high-dose vitamin D3 did not significantly change body weight (−0.7 kg; (95% CI: −3.5, 2.0)), body mass index (−0.2 kg/m2; (95% CI: −1.2, 0.7)), muscle area (−1.7 cm2; (95% CI: −9.6, 6.3)), muscle attenuation (−0.4 HU; (95% CI: −4.2, 3.2)), visceral adipose tissue area (−7.5 cm2 ; (95% CI: −24.5, 9.6)), or subcutaneous adipose tissue area (−8.3 cm2; (95% CI: −35.5, 18.9)) over the first 8 cycles of chemotherapy. Among patients with advanced or metastatic colorectal cancer, the addition of high-dose vitamin D3 , vs standard-dose vitamin D3 , to standard chemotherapy did not result in any changes in body composition. |
