Single center interventional study to explore activity of fibroblasts in the tumor and away in the healthy rectal tissue.


Patients included in the trial will have new biopsy performed before starting the Radiation Therapy and Chemotherapy (RT-CT). These biopsies will study the activity of fibroblasts in the tumor and away in the healthy rectal tissue. Within 8 to 10 weeks after the end of RT-CT, patients will have cancer surgery by proctectomy (with complete removal of the meso-rectum). On the resection specimen, new samples will be taken at the level of the tumor and away from the rectum.This study is single center interventional exploratory .
