What this trial studies

This clinical trial investigates the use of alfacalcidol, a form of vitamin D, to alleviate oral mucositis in patients undergoing TPF chemotherapy for oral squamous cell carcinoma. The study aims to determine if vitamin D can protect oral mucosal tissue and improve the quality of life for these patients by reducing inflammation and side effects associated with chemotherapy. Participants will be randomly assigned to receive either the vitamin D treatment or a placebo, and their progress will be monitored throughout the chemotherapy regimen.

Who should consider this trial

Good fit: Ideal candidates are patients aged 20-70 with pathologically diagnosed oral squamous cell carcinoma requiring TPF chemotherapy and who have low to adequate vitamin D levels.

Not a fit: Patients with existing oral mucosal diseases or severe systemic conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for chemotherapy patients by reducing painful oral mucositis.

How similar studies have performed: Previous studies have indicated that vitamin D may have protective effects against oral squamous cell carcinoma, suggesting potential for success in this approach.
