What this trial studies

This clinical trial investigates the effects of Lactobacillus rhamnosus GG (LGG) on alleviating oral mucositis in patients undergoing radiotherapy for head and neck cancers. Oral mucositis is a common and painful side effect of radiation treatment, significantly impacting patients' quality of life and treatment adherence. The study involves administering LGG powder to participants and comparing its effects against a placebo while they receive radiotherapy. The goal is to determine if LGG can reduce the severity of oral mucositis and improve overall patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-80 with non-metastatic head and neck malignant tumors who are scheduled to receive radiotherapy.

Not a fit: Patients with known allergies to Lactobacillus Reuteri components or those with serious medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the incidence and severity of oral mucositis, enhancing the quality of life for patients undergoing radiotherapy.

How similar studies have performed: Previous studies have shown promising results with probiotics in managing oral mucositis, suggesting potential for success in this approach.
