Lower Vitamin D Levels Predict Poor Survival Outcomes in Melanoma:
In patients with melanoma, lower 25-hydroxyvitamin D (vitamin D) levels were associated with poorer survival outcomes, according to a prospective study. Using 20 ng/mL as a clinical cutoff, those with deficient vitamin D levels had a significantly worse overall survival than those above that mark, with a hazard ratio (HR) of 1.44 (P
= .0036). The same was true for melanoma-specific survival, with an HR of 1.37 (P
= .0475). Read more
