Abstract

Background And Aim: Hepatocellular carcinoma (HCC) is a life-threatening condition of the liver, often concurrent with vitamin D deficiency. In this study, we investigated the relationship between HCC patients' vitamin D levels and overall survival.

Materials And Methods: We retrospectively enrolled patients that were being followed on their HCC diagnosis. We collected and examined data on patients' 25-OH vitamin D levels one month before diagnosis or at any point thereafter. We took levels below 10 ng/mL to indicate severe deficiency, levels between 10 ng/mL and 20 ng/mL to indicate moderate deficiency, and levels between 20 ng/mL and 30 ng/mL to indicate mild deficiency. We then analyzed the effects of vitamin D levels on patients' survival for each of these brackets.

Results: We included 85 patients in our survival analyses. We found 9 ng/mL to be the significant cutoff vitamin D level for survival. Vitamin D levels were lower in cases of advanced disease. Univariate analysis showed that advanced Barcelona Clinic Liver Cancer (BCLC) grades, vitamin D levels below 9 ng/mL, and alpha-fetoprotein (AFP) levels above 400 ng/dL had a negative significant effect on survival. Multivariate analysis showed that only advanced BCLC grades and AFP levels above 400 ng/dL had a negative significant effect.

Conclusion: In our study's cohort, HCC grades and AFP levels had a substantial negative impact on patients' overall survival. We found no connection, however, between vitamin D levels and overall survival.
