Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children and young adults aged 4 to 25 years receiving high-risk chemotherapy that is known to cause severe mucositis.
✕Probably not a fit
Patients who already have mucositis or other mouth lesions at the start of chemotherapy may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This clinical trial evaluates the effectiveness of low-level laser therapy (LLLT) in preventing severe oral mucositis in children and young adults undergoing high-risk chemotherapy regimens. Participants aged 4 to 25 years, who are free of mucositis at the start of treatment, will receive either LLLT or a placebo during their chemotherapy. The study aims to determine if LLLT can significantly reduce the incidence of grade 3-4 mucositis, which can cause severe pain and complications during cancer treatment.
Why it matters
Potential benefit: If successful, this therapy could significantly reduce the incidence of painful mouth sores in young cancer patients, improving their quality of life during treatment.
How similar studies have gone: Previous studies have shown promising results with low-level laser therapy in reducing mucositis in various patient populations, suggesting potential for success in this context.
