What this trial studies

This phase III, double-blind, randomized study aims to compare two protocols of low-power laser therapy to prevent oral mucositis and oropharyngeal pain in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). Patients will be divided into two groups, each receiving different dosimetry of laser treatment, and will be evaluated for pain, dysphagia, and the need for total parenteral nutrition and opioids. The study will take place at the Bone Marrow Transplant Center of the Instituto Nacional de Cancer in Brazil, with strict eligibility criteria to ensure patient safety and cooperation. Randomization will be conducted using the REDCap® program to maintain the integrity of the trial.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are scheduled for allogeneic HSCT and have intact oral mucosa.

Not a fit: Patients currently receiving medication for mucositis treatment or those not evaluated by the dental team will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce oral pain and complications for patients undergoing HSCT.

How similar studies have performed: Previous studies have shown promising results with low-level laser therapy in similar contexts, suggesting potential effectiveness.
