Brief summary

This pilot clinical trial studies L-lysine in treating oral mucositis in patients undergoing radiation therapy with or without chemotherapy for head and neck cancer. L-lysine may lessen the severity of oral mucositis, or mouth sores in patients receiving radiation therapy with or without chemotherapy for head and neck cancer

Detailed description

PRIMARY OBJECTIVES: I. To determine the complete response rate, decrease in severity, and time to complete response of oral mucositis related to head and neck cancer irradiation and chemotherapy after using L-lysine supplementation daily. SECONDARY OBJECTIVES: I. To determine the functional impact of use of L-lysine for oral mucositis on daily life as measured by the Functional Life Index-Cancer (FLIC) Questionnaire total score. OUTLINE: Patients receive L-lysine orally (PO) once daily (QD) until completion of radiotherapy and resolution of mucositis in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up weekly until mucositis resolves.

Design outcomes

Primary

MeasureTime frameDescription
Decrease in mucositis severity and time to complete responseWeekly post-treatment until Grade 0 mucositis is achievedComplete Response will be documented by complete resolution of oral mucositis, as defined by the Radiation Therapy Oncology Group (RTOG) grading scale. If the true percent of patients that respond is 20%, we will have a 90% chance of seeing at least 1 patient in 10 with a response. If none of the 10 patients show significant improvement in time to response, then we can be 90% confident that the true rate of significant improvement is less than 20%.

Secondary

MeasureTime frame
Improvement in quality of lifeWeekly post-treatment until Grade 0 mucositis is achieved
