Experimental: Autologous Fecal Microbiota Transplantation
Patients will receive autologous fecal microbiota transplantation (MaaT011- 150 mL rectal enema) - 2 administrations 24 hours apart.

Drug: Autologous Fecal Microbiota Transplantation
Other Name: MaaT011 |
- Evaluation of AFMT efficacy in dysbiosis correction by measure of microbiota diversity [ Time Frame: 40 days ]Comparison of Alpha and Beta diversity indexes at baseline, after chemotherapy and after AFMT will be performed
- Evaluation of AFMT efficacy in MDRB eradication based on bacterial culture [ Time Frame: 40 days ]MDRB carriage and resistome will be compared at baseline, after chemotherapy and after AFMT
- Definition of a dysbiosis biosignature using combination of biological parameters [ Time Frame: 40 days ]Microbiota sequencing results will be correlated with immune parameters
