Purpose
STUDY PURPOSE: To examine how effective probiotics are in preventing radiation-induced diarrhea versus placebo
TYPE OF STUDY: Systematic review
Search Strategy
DATABASES USED: MEDLINE, EMBASE
INCLUSION CRITERIA: Randomized, controlled trial; adults aged 18 and older, concurrent chemotherapy; presence of diarrhea included as outcome or enough data provided to calculate
EXCLUSION CRITERIA: Absence of placebo group; use of probiotics for treatment other than prevention of diarrhea; not in English
Literature Evaluated
TOTAL REFERENCES RETRIEVED: 63 retrieved
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Only randomized, controlled trials were pulled for this study.
Sample Characteristics
- FINAL NUMBER STUDIES INCLUDED = 4
- TOTAL PATIENTS INCLUDED IN REVIEW = 917
- KEY SAMPLE CHARACTERISTICS: Chitapanarux et al. study—63 female patients receiving RT and cisplatin chemotherapy for cervical cancer; Delia et al. study—490 patients receiving RT for colon, rectal, or cervical cancer; Germain et al. study—246 patients receiving RT for rectal, cervical, endometrial or prostate cancer; Giralt et al. study—118 patients receiving RT and cisplatin chemotherapy for cervical or endometrial cancer
Phase of Care and Clinical Applications
PHASE OF CARE: Active antitumor treatment
Results
The Chitapanarux and Delia studies were most robust and the Giralt study was least robust. The Germain study could not be determined. There were no adverse events reported in the studies. The Chitapanarux and Delia studies determined that probiotics were beneficial and produced statistically significant results in the study population. The Germain study reported benefits that were statistically significant at standard dose and at high dose, which was not statistically significant. Studies revealed high clinical significance.
Conclusions
Evidence supporting contention that probiotics are beneficial is low quality.
Limitations
- Scope
- Objectivity
- No second reviewer
Nursing Implications
More research is needed on the use of probiotics with rigorous randomized placebo controlled studies.
