New radiation technique aims to cut side effects for uterine cancer patients
NCT ID NCT05869123
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a newer type of radiation therapy called online adaptive radiotherapy (oART) for people who have had surgery for endometrial or cervical cancer. The goal is to see if using smaller treatment margins can reduce side effects while still effectively targeting any remaining cancer cells. The study involves 17 participants and tracks both immediate and long-term side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients must be informed of the investigational nature of this study and give written informed consent before treatment. 2. Postoperative endometrial and cervical cancer patients with pathologically confirmed no residual tumor at the resection margin and no evidence of distant metastasis (FIGO stage IVB). 3. Pathological findings indicate risk factors and adjuvant radiotherapy are prescribe. 4. Karnofsky score ≥ 70. 5. Subjects aged ≥ 18 years and ≤ 70 years. 6. No evidence of para-aortic metastatic lymph nodes. 7. No contraindications to CT scanning. 8. Subjects must be able to cooperate in completing the entire study. 9. Adequate marrow: neutrophile granulocyte count ≥1.5\*10\^9/L, hemoglobin ≥ 80 g/L, platelet count ≥100\*10\^9/L. 10. Normal liver and kidney function: Creatinine (Cr) \< 1.5 mg/dl, Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST) \< 2\*upper limit of normal (ULN). Exclusion Criteria: 1. Subjects who have received prior pelvic radiotherapy. 2. Subjects with other primary malignancies. 3. Subjects with contraindications to radiotherapy, as determined by the investigators. 4. Any severe disease which may bring unacceptable risk or affect the compliance of the trial, for example, unstable cardiac disease requiring treatment, renal disease, chronic hepatitis, diabetes with poor control, and emotional disturbance. 5. Active infection with fever. 6. Active inflammatory bowel disease.
