What this trial studies

This study aims to evaluate the effectiveness of Compound Glutamine Enteric-Coated Capsules (CGECC) combined with thalidomide compared to CGECC alone in preventing radiation-induced oral mucositis in patients undergoing radiotherapy for oral malignant tumors. Participants will be randomly assigned to receive either the combination treatment or CGECC alone. The primary endpoint is to measure the median time to the onset of Grade II oral mucositis, which is defined as the number of days from the start of radiation therapy until the occurrence of this condition.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with postoperative oral malignant tumors requiring radiotherapy and who have received more than 45Gy of radiation in the oral area.

Not a fit: Patients with conditions that prevent normal renal or liver function, or those with an ECOG performance status greater than 1, 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 in patients receiving radiation therapy.

How similar studies have performed: While there have been studies on preventing oral mucositis, the specific combination of CGECC and thalidomide is a novel approach that has not been extensively tested.
