Letter to the Editor: Serum bioavailable 25-hydroxyvitamin D levels correlate with hepatocellular carcinoma survival.

It was with great interest that we read the article entitled "Serum Bioavailable, Rather Than Total, 25-hydroxyvitamin D Levels Are Associated With Hepatocellular Carcinoma Survival" by Fang et al [1]. In this study, the authors investigated the relationship between total, free and bioavailable serum 25-hydroxyvitamin D (25OHD) levels and survival in a large prospective cohort of patients with hepatocellular carcinoma (HCC).
