Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Change of microbiota profile after 1 year of vitamin D supplementation. ;Secondary Objective: ¿microbiota composition may interact with vitamin D supplementation in changing 25(OH)D serum level. ¿Microbiota and vitamin D status in association with CRC stage and Ki67 expression. ¿VDR, vitamin D binding protein (serum DBP and GC) polymorphism, CYP 27A1 and CYP24A1 polymorphisms and their possible interferences on vitamin D and microbiota interaction. ;Primary end point(s): bacterial composition modification after 1 year of vitamin D administration;Timepoint(s) of evaluation of this end point: at the end of a 12 months treatment period | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): whether Vitamin D receptors, GC and serum level of 25(OH)D, at baseline, are associated with colorectal cancer prognostic factors; whether microbiota composition is associated with colorectal cancer prognostic factors; changes in proliferation evaluated by Ki67 LI on the primary tumor and normal rectal mucosa pre and post treatment; Comparison of lumen and adherent mucosal microbiota composition;Timepoint(s) of evaluation of this end point: 6 months from the end of the treatment of the last patient enrolled ; 6 months from the end of the treatment of the last patient enrolled; 6 months from the end of the treatment of the last patient enrolled; 6 months from the end of the treatment of the last patient enrolled | — |
