Changes of gut microbial communities in malignancy patients receiving pelvic/abdominal radiotherapy after probiotics administration to prevent radiation enteropathy. [ Time Frame: 42 days ] [ Designated as safety issue: No ]
  • 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.

Effects of Probiotics Supplementation on Intestinal Microbiome in Malignancy Pts(Get Pelvic/Abdominal Rtx)
Double Blind Placebo Controled Randomized Trial, Effects of Probiotics Supplementation on Intestinal Microbiome in Malignancy Patients Who Get Pelvic/Abdominal Radiotherapy

The purpose of this study is to evaluate the effect of probiotics to improve the intestinal microbiome in malignancy patients who get pelvic/abdominal radiotherapy.

Pelvic/abdominal radiotherapy carries a risk of complications. Acute complications include diarrhea, abdominal pain, inflammatory change in the small intestine. Radiation creates changes in bacterial microbiome, the vascular permeability of the mucosal cells and in intestinal motility. Probiotics were known to improve gastrointestinal function. This is a randomized, double-blind, placebo-controlled study involving 26 patients designed to evaluate the effect of probiotics to change the intestinal microbiome in in patients undergoing concurrent pelvic/abdominal RT.

  • Dietary Supplement: probiotics (six probiotic cultures)
    Effects of probiotics supplementation on intestinal microbiome; 2capsule bid orally for six weeks, 1capsule(500mg) Started eating probiotics one week prior of radiation therapy.
  • Dietary Supplement: Placebo
    Placebo intake for 6 weeks(including 5weeks of Rtx) and it take one tablet twice a day.
  • Experimental: probiotics

    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.

    Intervention: Dietary Supplement: probiotics (six probiotic cultures)
  • Placebo Comparator: placebo

    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.
