PG - 50-65 LID - 10.1111/jcpt.13292 [doi] AB - WHAT IS KNOWN AND OBJECTIVE: Cancer is one of the most important causes of morbidity and mortality worldwide. Pro-, pre- and symbiotics can modulate host metabolism and gut microbiota and potentially help prevent cancer and modulate the adverse effects (AEs) of treatments. Numerous studies on this role for pro-, pre- and symbiotics have reported inconsistent results. The purpose of this review was to examine current scientific evidence from randomized controlled trials (RCTs) on the effects of pro-, pre- and symbiotics on the incidence of complications and AEs, especially diarrhoea, in cancer management. METHODS: A systematic literature search was implemented in MEDLINE using the MeSH terms "probiotics", "prebiotics", "symbiotics" and "neoplasms", according to PRISMA guidelines. Reference lists were also handsearched to identify additional eligible RCTs. Three reviewers independently assessed the eligibility of each RCT. Of 714 retrieved abstracts, 22 articles with 2287 participants were included in the analysis. RESULTS AND DISCUSSION: The most studied bacteriotherapies were probiotics and symbiotics, in 10 and 7 studies, respectively. Both Lactobacillus and Bifidobacterium strains were used in 18 studies, while Lactobacillus and Bifidobacterium strains were individually used in 9 and 2 studies, respectively. Diarrhoea incidence rates were 3.2%-39.1% in intervention groups and 6.7%-60.9% in control groups, while infection incidence rates were 11.1%-22.7% in intervention groups and 17.3%-28.7% in control groups. WHAT IS NEW AND CONCLUSIONS: Pro-, pre- and symbiotics may potentially be efficacious in reducing complications associated with chemotherapy, radiotherapy and surgery in patients with cancer.
