Postoperative Hypofractionated Radiotherapy for Stage II/III Thymic Epithelial Tumors
Official title: A Prospective, Single-Arm Phase II Clinical Study of Hypofractionated Adjuvant Radiotherapy After Complete Resection for Stage II/III Thymic Epithelial Tumors
Run by Tianjin Medical University Cancer Institute and Hospital · NCT07691619 · Data updated 2026-11-12
This study tests whether giving a shorter course of higher-dose radiotherapy after complete tumor removal is safe for adults with Stage II/III thymic epithelial tumors.

Is this trial a fit for you?
✓Likely a good fit
Adults 18-75 with histologically confirmed thymic epithelial tumors (thymoma or thymic carcinoma) after complete resection (R0) and good functional status (ECOG 0-1).
✕Probably not a fit
Patients with unresected disease, poor performance status, or inadequate organ function may not benefit and could experience treatment-related risks.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective, open-label, single-arm Phase II trial evaluating the safety of adjuvant hypofractionated radiotherapy after complete resection of thymic epithelial tumors. Participants receive a total of 40 Gy in 15 fractions (2.67 Gy per day, 5 days a week for 3 weeks). Primary focus is on treatment-related safety and tolerability, with secondary looks at preliminary efficacy, economic impact, and quality of life. Eligibility includes adults 18-75 with Masaoka-Koga Stage II-III disease, good performance status, and adequate organ function following R0 resection. The study will be conducted at Tianjin Medical University Cancer Institute and Hospital.
Why it matters
Potential benefit: If successful, patients may receive a safe, shorter radiotherapy course that potentially reduces treatment burden while maintaining disease control.
How similar studies have gone: Prior work in thymic tumors has explored adjuvant radiotherapy, but this specific hypofractionated approach after complete resection is being studied with limited prior data.

Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Patients who voluntarily agree to participate in this study, sign the informed consent form, demonstrate good compliance, and are willing to comply with scheduled follow-up visits. 2. Age 18-75 years, male or female. 3. Histopathologically confirmed thymoma or thymic carcinoma after R0 complete resection. Eligible disease stages according to the Masaoka-Koga staging system include Stage II-III thymic carcinoma, Stage IIA Type B3 thymoma, Stage IIB Type B2/B3 thymoma, and Stage III thymoma. 4. Eastern Cooperative Oncology Group performance status of 0-1. 5. Life expectancy of at least 3 months. 6. Adequate major organ function to meet the requirements of study treatment, including bone marrow, hepatic, renal, and coagulation function according to protocol-specified criteria. 7. Patients with reproductive potential must agree to use medically acceptable contraception during study treatment and for 6 months after completion of study treatment. Female patients of childbearing potential must have a negative pregnancy test before enrollment and must not be breastfeeding. Exclusion Criteria: 1. Patients who do not meet the protocol-specified requirements for pathological type, disease stage, or histological subtype. 2. Patients who have not undergone surgical treatment, or who underwent R1 or R2 resection, or who have definite gross residual disease. 3. Prior thoracic radiotherapy. 4. Major surgery other than the tumor resection procedure or severe trauma within 4 weeks before the first radiotherapy treatment. 5. Uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage. 6. Prior or ongoing non-protocol-specified antitumor therapy, including immunotherapy, targeted therapy, radiotherapy, or other investigational treatment. 7. Active autoimmune disease or a history of severe autoimmune disease that, in the investigator's judgment, makes the patient unsuitable for radiotherapy. 8. History of immunodeficiency, including HIV positivity, history of organ transplantation, or history of allogeneic bone marrow transplantation. 9. Uncontrolled severe cardiovascular disease, such as New York Heart Association Class II or higher heart failure, unstable angina, myocardial infarction within 1 year, or severe arrhythmia requiring clinical intervention. 10. Severe infection within 4 weeks before the first radiotherapy treatment, or active pulmonary inflammation indicated by baseline imaging. 11. History of interstitial lung disease, history of non-infectious pneumonitis, or Grade 3 or higher pulmonary dysfunction confirmed by pulmonary function testing. 12. Active pulmonary tuberculosis, active hepatitis B infection, or active hepatitis C infection. 13. Diagnosis of another malignancy before the first radiotherapy treatment, except for low-risk malignancies that have been adequately treated. 14. Any other condition that, in the investigator's judgment, may affect patient safety, compliance, or the collection of study data.
