Hypofractionated Adjuvant Radiotherapy for Thymic Epithelial Tumors
Taiwan69 participantsStarted 2026-08-01
Plain-language summary
This is a multi-center, open-label, single-arm, prospective interventional study evaluating hypofractionated adjuvant radiotherapy (HART) after radical thymothymectomy in patients with thymic epithelial tumors. The study estimates 5-year local control and prospectively characterizes acute and late treatment-related adverse events, quality of life, cardiopulmonary function, and patterns of failure. Photon therapy and proton therapy are both protocol-acceptable modalities and are selected by shared decision-making rather than randomization.

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?

. Women of childbearing potential must have a negative qualitative serum or urine pregnancy test within 14 days prior to study entry.
Exclusion criteria
. Prior radiotherapy to the thorax.
. Severe active comorbidities that, in the judgment of the investigator, make the patient inappropriate for study entry, interfere with safety or adverse event assessment, or limit compliance with study requirements, including: uncontrolled active infection requiring intravenous antibiotics at registration; transmural myocardial infarction \<= 6 months prior to registration; unstable angina or congestive heart failure requiring hospitalization \<= 6 months prior to registration; life-threatening uncontrolled clinically significant cardiac arrhythmias; hepatic insufficiency resulting in clinical jaundice and/or coagulation defects; chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at registration; uncontrolled psychiatric disorder.
. Planned receipt of another investigational treatment during radiotherapy.
. Planned concurrent chemotherapy during radiotherapy. Prior induction or neoadjuvant chemotherapy, or planned sequential adjuvant chemotherapy after adjuvant radiotherapy, is allowed.
. Pregnant or breastfeeding women.
. Women of childbearing potential and sexually active male participants who are unwilling or unable to use medically acceptable contraception during radiotherapy and for 3 weeks after completing treatment.
