Ozone Therapy for Cancer Therapy-Related Oral Mucositis
Italy58 participantsStarted 2023-11-01
Plain-language summary
This retrospective observational study will evaluate clinical data already available from adult cancer patients who developed cancer therapy-related oral mucositis during radiotherapy and/or chemotherapy and who were managed in routine clinical practice with combined chairside and domiciliary ozone therapy.
The study will not assign participants to any treatment and will not involve any new intervention, visit, examination, or change in patient care. Data will be extracted from existing medical records and clinical documentation.
The main purpose of the study is to describe the clinical course of oral mucositis and to evaluate the time needed to reach oral mucositis grade 1 or lower according to the World Health Organization Oral Toxicity Scale. The study will also assess changes in oral pain intensity, measured using a 0 to 10 Visual Analogue Scale, from baseline to follow-up visits up to 15 days.
Exploratory analyses will compare clinical trends between patients with head and neck cancers and patients with cancers in other anatomical sites. The results will be interpreted as descriptive and exploratory because the study is retrospective, single-arm, and has no control group.

* Availability of relevant demographic and clinical information required for the retrospective analysis
Exclusion Criteria:
* Age younger than 18 years
* Absence of a documented diagnosis of cancer therapy-related oral mucositis

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.
