Malignancy
YES
1. Targeting on cancers in gastrointestinal tract (esophageal cancer, gastric cancer and colon cancer), we examine relationship between relapse free survival and serum vitamin D concentration/single nuclear polymorphisms of vitamin D receptor
2. By peroral administration of either vitamin D3 (2,000IU) or placebo in double blind manner, vitamin D can prevent relapse and death after primary operation.

The 5-year RFS was 77% vs 69%; hazard ratio (HR) for relapse or death, 0.76; 95% CI, 0.50 -1.14; P = 0.18. The 5-year overall survival in the vitamin D and placebo groups was 82% vs. 81%; HR for death, 0.95; 95%CI, 0.57-1.57; P=0.83. In a subgroup of patients with serum 25(OH)D levels between 20 and 40 ng/mL at baseline, the 5-year RFS was 85% vs 71%; HR for relapse or death, 0.46; 95%CI, 0.24-0.86; P=0.02; Pinteraction=0.04.

The AMATERASU Trial was a randomized, double-blind, placebo-controlled trial at a single university hospital in Japan. Enrollment began in January 2010 and follow-up was completed in February 2018. Patients aged 30 to 90 years with cancers of the digestive tract from the esophagus to the rectum, stages I to III, were recruited. Of 439 eligible patients, 15 declined and 7 patients were excluded after operation.
The patients were randomized to receive oral supplemental capsules of vitamin D (2000 IU/day, n=251) or placebo (n=166) from the first postoperative outpatient visit to until the end of the trial.
Fractures occurred in 3 (1.3%) of vitamin D group and 5 (3.4%) of placebo. Urinary stones were in 2 (0.9%) of vitamin D and 0 (0.0%) of placebo.
The primary outcome was relapse-free survival (RFS) time to relapse or death.
The secondary outcome was overall survival time to death from any cause. Subgroups analyzed were baseline serum 25(OH)D level 0 to <20 ng/mL, 20 to 40 ng/mL, and >40 ng/mL; because of small sample size for highest level, interactions were tested only between the low and middle baseline levels.
