The Preventive and Therapeutic Effects of Spirulina Preparations on Ulcers of Oral Mucosa

Overview

This is a prospective, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the efficacy and safety of spirulina supplementation in patients with radiation-induced oral mucositis (RIOM) receiving radiotherapy for head and neck cancer. Participants will be randomly assigned to receive either spirulina tablets or placebo in addition to standard oral care during radiotherapy. The primary objective is to determine whether spirulina reduces the severity of oral mucositis. Secondary outcomes include the incidence and duration of severe oral mucositis, oral pain, nutritional status, quality of life, treatment interruption, and adverse events. The findings of this study may provide evidence for an effective and safe adjunctive intervention to improve the management of radiation-induced oral mucositis and enhance the quality of life of patients undergoing radiotherapy.

This study is a prospective, randomized, double-blind, placebo-controlled clinical trial evaluating spirulina as an adjunctive intervention for radiation-induced oral mucositis in patients receiving radiotherapy for head and neck cancer. Radiation-induced oral mucositis is a common and clinically significant adverse effect of radiotherapy. It may cause oral pain, difficulty eating and swallowing, nutritional deterioration, reduced quality of life, and interruption of anticancer treatment. Current management is mainly supportive, and additional safe and effective interventions are needed. Eligible participants will be randomized to receive either spirulina tablets or matching placebo in addition to standard oral care during radiotherapy. The study will compare the effects of spirulina and placebo on the severity, incidence, and duration of oral mucositis. Oral pain, nutritional status, quality of life, treatment compliance, radiotherapy interruption, and adverse events will also be evaluated. The purpose of this trial is to determine whether spirulina supplementation can reduce the burden of radiation-induced oral mucositis and improve supportive care for patients undergoing radiotherapy. The safety of spirulina will be monitored throughout the study.
