Abstract

Background

Patients with cancer undergoing radiotherapy often develop diarrhoea, causing distress and hindering treatment. As probiotics have favourable effects on the gut flora, they are potentially good candidates in the prevention of radiotherapy-induced diarrhoea (RID).

Purpose

The outcome of interest of this systematic review was the efficacy of probiotics in preventing RID.

Materials and methods

Medline and Embase databases were systematically searched. Four randomised controlled trials (RCTs) were finally selected.

Results

Three RCTs showed beneficial results, which were statistically significant. One RCT showed non-beneficial results, which were not statistically significant. The quality of the studies was mixed, and serious limitations were found.

Conclusion

While the indications are towards a benefit of the use of probiotics in preventing RID, more robust evidence is required in the form of well-designed RCTs.
