- Abstract
Background: To evaluate the relation between serum-25-hydroxy Vitamin-D levels (S25OHVDL) and concurrent chemoradiation therapy (CTRT) toxicities in patients of head and neck squamous cell cancer (HNSCC). Methods: After an institutional ethics committee approval, consecutive HNSCC patients who received radical/adjuvant CTRT were prospectively evaluated. Patients were assessed for CTRT toxicities using Common Terminology Criteria for Adverse Events version 5.0 (CTCAE-v5.0) and the response was evaluated according to Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST-1.1). S25OHVDL was assessed at the time of the first follow-up. Patients were divided into group A (Optimal) and group B (suboptimal) according to S25OHVDL. The treatment toxicities were correlated with S25OHVDL. Results: Twenty-eight patients were evaluated for the study. S25OHVDL was optimal in eight (28.57%) and suboptimal in 20 patients (71.42%). Mucositis and radiation dermatitis were significantly more in subgroup B (P-value 0.0011 and 0.0505, respectively). Relatively lower but nonsignificant hemoglobin and peripheral white blood cell counts were observed in subgroup B. Conclusion: Suboptimal S25OHVDL was associated with significantly more skin and mucosal toxicities in HNSCC patients treated with CTRT.
