|Official Title:||Double Blind Placebo Controled Randomized Trial, Effects of Probiotics Supplementation on Intestinal Microbiome in Malignancy Patients Who Get Pelvic/Abdominal Radiotherapy|
- Changes of gut microbial communities in malignancy patients receiving pelvic/abdominal radiotherapy after probiotics administration to prevent radiation enteropathy. [ Time Frame: 42 days ]
- 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.
- Prevention of any grade of diarrhea and gastrointestinal symptoms [ Time Frame: 42 days ]
- Gastrointestinal symptoms will be scored according the Gastrointestinal symptom rating scale before and after RTx.
- Diarrhea will be graded weekly according the Common Toxicity Criteria system.
