Detailed Description

This study is a national, multicenter, open-label randomized, 2-arm phase III non-inferiority trial. Patients with mid or low LARC (cT3N0 or cT1-T3N+ with CRM \> 2 mm on pretreatment MRI) will be ran...

Eligibility Criteria

Inclusion

  • Histologically proven middle or low rectal carcinoma, ≤ 10 cm from the anal verge on MRI (sagittal slide)
  • cT3N0 and/or cT1-T3N+ on pretreatment imaging work up (pelvic contrast enhanced MRI and/or endorectal ultrasound),

  • Informed consent signed
  • Patients of childbearing / reproductive potential should use adequate birth control measures during the study treatment period and for at least 6 months after the last study treatment. A highly effective method of birth control is defined as those which result in low failure rate (i.e. less than 1% per year) when used consistently and correctly.

Exclusion

  • Concomitant treatment with millepertuis.
  • contraindication to oxaliplatin :
  • \*bone marrow insufficiency before treatment initiation (neutrophil count \<2x109/L and/or platelet count \<100x109/L), peripheral neuropathy with permanent invalidity before treatment initiation
  • severe renal insufficiency (Creatinin clearance \<30 ml/min)
  • contraindications to folinic acid : Biermer anemia and other anemia related to B12 vitamin insufficiency
  • contraindications to capecitabin : severe renal insufficiency (Creatinin clearance \<30 ml/min), complete and permanent insufficiency in dihydropyrimidine dehydrogenase
  • live attenuated vaccine should not be used during and 6 months after preoperative treatment.
  • Previous colorectal cancer
  • Other concomitant or previous malignancy, except: i/ adequately treated in-situ carcinoma of the uterine cervix, ii/ basal or squamous cell carcinoma of the skin, iii/ cancer in complete remission for \>5 years
  • Presence of any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial
