Outcome Measures

Primary Outcomes (1)

  • Changes of gut microbial communities in malignancy patients receiving pelvic/abdominal radiotherapy after probiotics administration to prevent radiation enteropathy.

    * Comparison of overall microbial communities in fecal samples between probiotics treated patients and control cancer patients receiving radiation therapy. * To determine preventing effect of probiotics against radiation enteropathy, all the bacterial species level taxon derived from fecal samples of cancer patients will be identified by massive sequencing analysis and relative abundance of each taxon between two groups will be statistically compared. * In addition, overall microbial composition, kind of species and their abundance, in two groups will be compared with clustering method such as UPGMA and PCoA and the variation values between two groups will be calculated. * In the current study, we will determine the effectiveness of probiotics for the prevention of radiation induced complications with these two comparative analysis methods.

    42 days

Secondary Outcomes (1)

  • Prevention of any grade of diarrhea and gastrointestinal symptoms

Study Arms (2)

probiotics

EXPERIMENTAL

Probiotics supplementation group. Probiotics intake for 6 weeks(including 5weeks of Rtx) and it take one tablet twice a day. Probiotics is composed of Lactobacillus acidophilus, Streptococcus thermophilus, Bifidobacterium lactis, L. rhamnosus, B. longum and B. bifidum.

Dietary Supplement: probiotics (six probiotic cultures)

placebo

PLACEBO COMPARATOR

Placebo group. Placebo intake for 6 weeks(including 5weeks of Rtx) and it take one tablet twice a day. Placebo is composed of starch.Probiotics and placebo were similar in appearance, taste.

Dietary Supplement: Placebo

Interventions

Effects of probiotics supplementation on intestinal microbiome; 2capsule bid orally for six weeks, 1capsule(500mg) Started eating probiotics one week prior of radiation therapy.
