*4.2.3.2 Colorectal cancer*

Several studies demonstrate an inverse correlation between colorectal cancer and 25VD levels [58, 59]. The findings do not correspond to the results of a larger study, detecting no significant association between colorectal cancer and VD status [60]. Unfortunately, the data from interventional trails with VD supplementation also have conflicting result for the effect of VD on colorectal cancer prevention and survival improvement [44, 61]. Similarly to breast cancer, the data for the association between colorectal cancer and VD status in renal patients is limited.
