Primary Outcome Measures:
- The impact of the probiotic preparation on increasing the TRG1-2 rate. [ Time Frame: From the date of randomization until to the date of surgery, up to 18 weeks ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Determine whether VSL#3® can have an impact on reduction of acute bowel toxicity [ Time Frame: 12-36 months ] [ Designated as safety issue: Yes ]
- pathological complete response (pCR) [ Time Frame: 12-36 months ] [ Designated as safety issue: Yes ]
- impact on reduction of sphincter saving surgery (SSS) [ Time Frame: 12-36 months ] [ Designated as safety issue: Yes ]
- disease free survival (DFS) at 36 months [ Time Frame: 36 months ] [ Designated as safety issue: Yes ]
- Determine whether VSL#3® can have an impact on reduction of late toxicity at 12 and 36 months. [ Time Frame: 12, 36 months ] [ Designated as safety issue: Yes ]
