Summary

Prophylactic sucralfate did not prevent radiation proctopathy during pelvic radiotherapy and may worsen diarrhea. A meta-analysis confirmed no significant benefit for acute symptoms.

Area of Science:

  • Oncology
  • Gastroenterology
  • Radiotherapy

Background:

  • Pelvic radiotherapy frequently causes gastrointestinal symptoms, impacting treatment adherence.
  • Prophylaxis aims to prevent acute reactions and delayed radiation injury.
  • Sucralfate has been investigated for radiation side-effects, but results are conflicting.

Purpose of the Study:

  • To evaluate the efficacy of prophylactic sucralfate in preventing acute radiation proctopathy.
  • To conduct a meta-analysis of existing studies on sucralfate for radiation-induced gastrointestinal symptoms.

Main Methods:

  • A prospective, randomized, placebo-controlled trial involving 51 patients undergoing pelvic radiotherapy.
  • Patients received either sucralfate or placebo during radiotherapy.

  • Symptom assessment, endoscopy, and biopsies were performed at multiple time points.

    • Main Results:

    • An interim analysis of 44 patients showed significantly increased diarrhea in the sucralfate group, leading to trial cessation.
    • No differences were observed in other symptoms, endoscopic findings, or histology.
    • A meta-analysis of five studies found no statistically significant benefit of sucralfate for acute symptoms.

    Conclusions:

    • Sucralfate is not recommended for preventing acute radiation proctopathy.
    • Sucralfate may potentially exacerbate radiation-induced gastrointestinal symptoms.
