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.
Radiotherapy is an essential therapeutic tool for pelvic malignancies such as uterine cervix, uterine corpus, prostate, testicular, urinary bladder and rectal cancers. According to reports, the estimated number of new cases of malignant pelvic tumors in China in 2015 alone exceeded 500,000. Chronic radiation proctitis (CRP) is an unavoidable and commonly observed side effect, occurs 3 months later and in 5-20% of patients after pelvic malignancy radiation. Hematochezia is the most common symptom for more than 80% of CRP patients, which is a persistent, irreversible and progressive symptom, and will probably give rise to anemia. In clinic, the treatment for intractable bleeding of CRP is very difficult.
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. A large number of studies have shown that thalidomide can be used to treat Crohn's disease, ulcerative colitis, radiation cystitis, etc., and it can treat moderate to severe of IBD patients can inhibit inflammatory response, improve clinical symptoms, promote intestinal mucosal repair. Further, recent studies have proved that thalidomide can be used to treat intestinal bleeding due to vascular dysplasia. And a case report from Gut described that refractory bleeding of CRP of a 78-year-old woman were significantly alleviated after taking thalidomide.
Therefore, for the patients of CRP with intractable bleeding, a prospective, open clinical trial planed to carry out to observe the safety and effectiveness of thalidomide in treating hemorrhagic CRP.

| Thalidomide | Drug | 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. The medication time was 1 month. Maintenance period: The oral dose of thalidomide was 50-75mg/d. The medication time was 3 months. |

| Remission rate of rectal bleeding one month after thalidomide treatment | Remission of rectal bleeding was defined as the score of Subjective Objective Management Analysis system (SOMA) for retcal bleeding at least 1 grade lower and the hemoglobin level at least 10g/L higher than that before treatment. The SOMA score for hematochezia was ranged from 1 to 4, with the higher the score, the more serious. | the first month after thalidomide treatment |
