Brief Summary

The purpose of this clinical study is to evaluate whether Bifidobacterium Triple Viable Capsules, alone or in combination with Gegen Qinlian Decoction, can effectively prevent and treat acute radiation enteritis in patients undergoing abdominal or pelvic radiotherapy. The study aims to answer the following question: Can probiotics, with or without the addition of herbal medicine, reduce the incidence and severity of radiation-induced intestinal injury and improve the quality of life for patients during and after radiotherapy? A total of 60 patients with malignant tumors receiving abdominal or pelvic radiotherapy will be recruited and randomly assigned to one of three groups: a control group (no intervention), a probiotics-only group (Bifidobacterium Triple Viable Capsules, three capsules twice daily), and a combination therapy group (probiotics with modified Gegen Qinlian Decoction tailored to individual symptoms). The primary outcome will be the incidence and severity of acute radiation enteritis, assessed using the RTOG/EORTC grading criteria (0-IV levels). Daily observations will be recorded during radiotherapy, with follow-up lasting three months after the completion of treatment. This study seeks to provide evidence for the use of probiotics and herbal medicine as effective strategies to mitigate the side effects of radiotherapy and improve patient outcomes.

Conditions

Acute Radiation Enteritis

Outcome Measures

Primary Outcomes (1)

• Incidence of Acute Radiation Enteritis

  The incidence of acute radiation enteritis will be assessed using the RTOG/EORTC grading criteria (Grade 0-IV). Symptoms such as diarrhea, abdominal pain, and mucus secretion will be monitored daily during radiotherapy and up to three months post-treatment. The outcome will measure the proportion of patients experiencing Grade II or higher symptoms in each study arm. This assessment aims to evaluate the effectiveness of Bifidobacterium Triple Viable Capsules, alone or in combination with Gegen Qinlian Decoction, in reducing the incidence of radiation enteritis.

  From the start of radiotherapy to 3 months post-treatment

Study Arms (1)

Probiotics With Gegen Qinlian Tang Group

EXPERIMENTAL

Participants in this group will receive an oral placebo matched in appearance to the Bifidobacterium Triple Viable Capsules, taken three times daily for 8 weeks. No active interventions will be administered in this group, serving as the placebo control.

Drug: Probiotic Therapy With Gegen Qinlian Tang

Interventions

Probiotic Therapy With Gegen Qinlian Tang DRUG

This intervention includes the oral administration of Bifidobacterium Triple Viable Capsules (0.5 g, three times daily) combined with Gegen Qinlian Tang (200 mL, twice daily) for 8 weeks. The combination therapy is designed specifically for the prevention and treatment of radiation enteritis, differentiating it from probiotics or herbal therapies used alone.
