Sialendoscopy Versus Photobiomodulation in Prevention of Radiation Induced Xerostomia

Egypt42 participantsStarted 2026-04-01

Plain-language summary

Radiation induced xerostomia (RIX) represents a common debilitating side effect for (RT), adversely affecting oral health and hindering head and neck cancer (HNC) patients' quality of life (QOL). To date, managing (RIX) is mainly symptomatic, while the only FDA-approved preventive therapeutic agent is Amifostine, with associated systemic toxicities. Sialendoscopic management is a minimally invasive technique that can help in restoring ductal patency, decreasing inflammation and improving salivary flow. Laser Photobiomodulation (PBM) is a noninvasive approach that enhances salivary gland function by stimulating cellular activity, increasing blood flow and attenuating oxidative stress. Aim: The present study aims to evaluate and compare the efficacy of sialendoscopic management and photobiomodulation in managing (RIX) in (HNC) patients. Materials and Methods: A randomized clinical trial will be carried out on 42 (HNC) patients. Directly prior to the first (RT) session, Group I (n= 14 patients) will receive sialendoscopic management. Group II (n=14 patients) will receive (PBM) sessions. Group III (n= 14 patients) will receive basic oral care (BOC). Xerostomia will be evaluated at baseline, at 3 weeks and after 8 weeks from the end of (RT), clinically using Common Terminology Criteria for Adverse Events (CTCAE) v5.0 and objectively using unstimulated salivary flow. Quality of life will be assessed using Multidisciplinary Salivary Gland Society (MSGS) questionnaire. Salivary amylase will be assessed at baseline and after 8 weeks from the end of (RT).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients who are going to receive (IMRT) as a treatment of (HNC) either as postoperative (adjuvant) therapy or definitive therapy. * Patients who are planned to receive (RT) with parotid mean dose bilaterally not exceeding 25 Gy. * Males and females with an age not less than 18 years30 Exclusion Criteria: * Patients suffering from uncontrolled systemic diseases (such as diabetes, hypertension, cardiovascular, liver or renal dysfunction). * Patients with history of using drugs such as (pilocarpine ), oral humidifiers or herbs that prevent or treat xerostomia 2 months prior to study inclusion. * Patients with findings of any physical or mental abnormality which would interfere with or be affected by the study procedure. * Patients diagnosed with Sjögren's disease or other underlying systemic illness that is known to cause xerostomia.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
