Radiation-induced intestinal damage: latest molecular and clinical developments

Area of Science:

• Oncology
• Gastroenterology
• Radiotherapy

Background:

• Radiotherapy is crucial for cancer treatment but can cause significant intestinal side effects.
• Radiation-induced intestinal damage, including enteritis and mucositis, impacts patient quality of life and treatment outcomes.

Purpose of the Study:

• To systematically review prophylactic and therapeutic interventions for mitigating intestinal symptoms in cancer patients undergoing radiotherapy.
• To assess the current evidence base for managing radiation-induced intestinal damage.

Main Methods:

• A comprehensive literature search was performed in PubMed using keywords like 'radiation enteritis' and 'radiation mucositis'.
• Inclusion criteria comprised in vivo studies, clinical trials, and meta-analyses published in English, with no date restrictions.
• Reference lists of selected studies were also reviewed to identify additional relevant literature.

Main Results:

• The review examined the pathogenesis of acute and chronic radiation-induced intestinal damage.
• Various prevention and treatment approaches were analyzed based on the available literature.
• Current evidence is insufficient to strongly recommend any single strategy for reducing radiation-induced intestinal damage.

Conclusions:

• There is a lack of robust evidence supporting specific interventions for radiation-induced intestinal damage.
• High-quality randomized controlled trials are essential to evaluate interventions with preliminary positive findings.
• Further research is required to establish effective strategies for preventing and treating gastrointestinal side effects of radiotherapy.
