An interventional study of Hypofractionated Radiation Therapy in Thymoma and Thymic Carcinoma, Thymoma and Thymic Cancer, sponsored by Rongrong Zhou. Recruiting at 1 site in China. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2024-11-18.

The goal of this clinical trial is to learn if hypofractionated radiotherapy works to shorten the treatment time without increasing the side effects in patients of thymic epithelial tumors. The main questions it aims to answer are:
Participants will:
According to the World Health Organization histological classification system, thymic epithelial tumors (TET) are divided into thymoma and thymic carcinoma. Surgery is the main treatment for thymic tumors, and radiotherapy (RT), as an important auxiliary method of surgery, also plays an irreplaceable role in all stages of thymoma.
Hypofractionated radiotherapy is a common mode of radiotherapy for thoracic tumors. Unlike conventional radiotherapy, hypofractionated radiotherapy has a higher single dose and a shorter course of treatment. Because it improves the treatment efficiency, it can reduce the treatment time of patients and medical institutions and the cost of patients.
In the postoperative radiotherapy stage, conventional radiotherapy and hypofractionated radiotherapy were used. The course of hypofractionated radiotherapy was shorter than that of conventional radiotherapy. Patients chose to accept hypofractionated radiotherapy as the hypofractionated group, but not the conventional group.
133 studies on the registry are indexed under Thymoma; 37 are open to participants now.
This study's planned enrollment of 100 is above the median of 44 across 108 interventional studies indexed under Thymoma.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
