EXPERIMENTALInterventions
patients with unresectable local recurrent rectal cancer will be treated with carbon ion radiation therapy as re-irradiation
Eligibility Criteria
You may qualify if:
- \) pathologically confirmed rectal adenocarcinoma (including mucinous adenocarcinoma and signet-ring cell carcinoma) and LRRC confirmed by biopsy or clinical diagnosis,
- \) received a radical operation for their primary tumor and regional lymph nodes,
- \) received chemo-radiation or radiation in pelvic before CIRT,
- \) received re-irradiation by CIRT after their pelvic radiotherapy.
You may not qualify if:
- \) received more than once prior radiotherapy in the same treatment field,
- \) time to the last radiotherapy was \<1 year,
- \) space between the lesion to organ at risk (OARs) (bladder or digestive tract) was too close (\<5 mm).
