Efficacy and Safety of Thalidomide Combined With Glutamine in the Treatment of Radiation Intestinal Injury: a Single-center, Open-label, Randomized Controlled Study
At present, there is still a lack of standard and effective treatment strategies and procedures for radiation intestinal injury. Studies have shown that thalidomide can effectively treat refractory gastrointestinal bleeding caused by vascular malformation. Therefore, The investigators designed a single-center, open-label, randomized controlled study to evaluate the efficacy and safety of thalidomide combined with glutamine in the treatment of radiation intestinal injury.
• Age 18-80 years old, gender is not limited;
• Patients with hematochezia symptoms of chronic radiation intestinal injury: Due to the lack of diagnostic gold standard for radiation intestinal injury, a comprehensive analysis of clinical, endoscopic, imaging and histopathological findings was mainly performed to make the diagnosis of radiation intestinal injury on the basis of excluding infectious and other non-infectious intestinal injuries. Exposure to radioactive sources is a necessary factor in the diagnosis of radiation intestinal injury, and tumor activity or recurrence should be excluded.
• The proportion of dominant defecation bleeding in total defecation times in the week before treatment is not less than 20%;
• ECOG score: 0-2.
