This interim analysis of the randomized, placebo-controlled VICTORIA trial analyzed the first recruited 74 German adults with nonmetastatic colorectal cancer, a tumor surgery within the past year, and 25-hydroxyvitamin D levels (25(OH)D) < 50 nmol/L. Study participants received a loading dose tailored for a baseline 25(OH)D level and BMI in the first 11 days, followed by a maintenance dose of 2000 IU of vitamin D3 daily until end of trial week 12. The mean 25(OH)D levels were 27.6, 31.0, and 34.1 nmol/L in the placebo group and 25.9, 63.1, and 75.5 nmol/L in the verum group during screening, visit 1 (end of loading dose), and visit 2 (end of maintenance dose), respectively. The prevalence of 25(OH)D) ≥ 50 nmol/L at visits 1 and 2 was 3.5 KW - bolus (Other) KW - calcium (Other) KW - colorectal cancer (Other) KW - efficacy (Other) KW - loading dose (Other) KW - personalized medicine (Other) KW - randomized controlled trial (Other) KW - safety (Other) KW - treatment regimen (Other) KW - vitamin D (Other) LB - PUB:(DE-HGF)16 C6 - pmid:36364809 DO - DOI:10.3390/nu14214546 UR - https://inrepo02.dkfz.de/record/182558 ER -
