Summary

Chronic radiation proctitis (CRP) is the main secondary toxic injury after pelvic radiotherapy. Hematochezia is the most common symptom for more than 80% of CRP patients.

Non-surgical treatment is the first choice to the treatment of CRP to avoid the occurrence of serious complications. Conventional oral medication for the treatment of bleeding CRP is very few and has little effect. At present, no oral medication has been found to significantly alleviate and control refractory bleeding of CRP. Therefore, it is an urgent problem to screen out a drug that is more effective, safe and highly compliant for the treatment of hemorrhagic CRP.

Thalidomide has anti-inflammatory, immune regulation, anti-angiogenesis and other effects. For the patients of CRP with intractable bleeding, a prospective, open clinical trial will be carried out to observe the safety and effectiveness of thalidomide in treating hemorrhagic CRP.

Conditions

  • Chronic Radiation Proctitis

Interventions

DRUG

Thalidomide

The patients were treated with thalidomide tanken orally every night for 4 months, and the treatment period was divided into induction period and maintenance period, as follows: Induction period: The oral dose of thalidomide started at 50 mg, and increased to 100 mg after one week if tolerable, and maintain 100 mg for three weeks.
