Prediagnostic Circulating Concentrations of Vitamin D Binding Protein and Survival Among Patients with Colorectal Cancer

Abstract

Background: Higher total 25-hydroxyvitamin D [25(OH)D] levels are associated with improved survival among patients with colorectal cancer, but the relationships between circulating vitamin D binding protein (VDBP), and bioavailable or free 25(OH)D, and colorectal cancer survival remain unknown.

Methods: We examined the associations between prediagnostic plasma levels of vitamin D-related markers and survival among 603 White participants diagnosed with colorectal cancer from two prospective U.S. cohorts. Plasma VDBP and total 25(OH)D were directly measured, while bioavailable and free 25(OH)D was calculated using a validated formula on the basis of total 25(OH)D, VDBP, and albumin levels. Cox proportional hazards regression was used to estimate HRs for overall and colorectal cancer-specific mortality, with adjustment for other prognostic markers and potential confounders.

Results: Higher VDBP levels were associated with improved overall ( = 0.001) and colorectal cancer-specific survival ( = 0.02). Compared with patients in the lowest quartile, those in the highest quartile of VDBP had a multivariate HR of 0.58 [95% confidence interval (CI), 0.41-0.80] for overall mortality and 0.58 (95% CI, 0.37-0.91) for colorectal cancer-specific mortality. The results remained similar after further adjustment for total 25(OH)D levels. In contrast, neither bioavailable nor free 25(OH)D levels were associated with overall or colorectal cancer-specific mortality (all > 0.15).

Conclusions: Prediagnostic circulating concentrations of VDBP were positively associated with survival among patients with colorectal cancer.

Impact: The clinical utility of VDBP as a prognostic marker warrants further exploration, as well as research into underlying mechanisms of action.
