One group received zinc sulfate capsules (50 mg TDS daily after meals) and the other group received placebo (thrice after meals). Patients were advised to start taking capsules on the first day of their chemoradiation. Both the groups continued the capsules a month after their CCRT ended.Results: Sweet taste was most effected by cancer and its treatment followed by bitter and salty taste. Sour taste was least effected. When both the groups were compared for four tastes for detection threshold, the differences in observation at 3 stages of median IQR were not significant. For recognition threshold between zinc sulfate and placebo, no significant difference was observed in median IQR for salty taste and bitter taste. However, sweet taste (baseline p-value 0.245, end p-value 0.010, follow-up p-value 0.038) was statistically significant at end of CCRT and follow-up stage and sour taste (baseline p-value 0.24, end p-value 0.006, follow-up p-value 0.898) at end of CCRT only.Conclusion: Zinc sulfate was not found to be beneficial in preventing chemoradiation induced taste alterations. Taste and smell alterations are common in patients with cancer and do not receive sufficient support to manage taste alterations. This area requires more research to develop a comprehensive understanding of the nature and its management.Abbreviations: CCRT = Concurrent chemoradiotherapy. DT = Detection threshold.
