Summary

GRECCAR 15 is focused on Locally Recurrent Rectal Cancer (LRRC) for patients with previous pelvic radiotherapy for the primary rectal cancer. This situation leads to a 20% higher risk of non-curative resection for the LRRC management (R1 status) impacting significantly the overall survival. The widespread use of neoadjuvant radiotherapy for primary rectal cancer introduces this new problem: the treatment of LRRC in previously irradiated area.

The objective of GRECCAR 15 is to assess the efficacy of neoadjuvant chemotherapy followed by pelvic reirradiation versus neoadjuvant chemotherapy alone on the rate of curative surgery (R0) in previously irradiated patients with LRRC.

Conditions

Interventions

DRUG

Chemotherapy FOLFIRINOX, 6 cycles

* oxaliplatin: 85 mg/m2 * irinotecan: 180 mg/m² * folinic acid: 400 mg/m2 * 5FU : 400 mg/m2 (bolus) * 5FU : 2400 mg/m2 (continuous infusion)

RADIATION

Radiochemotherapy

Reirradiation consists in conformational intensity modulated external irradiation (Intensity-modulated radiotherapy Volumetric Modulated Arc Therapy or tomotherapy) delivering a 30.6 Gy dose with high-energy photons in fractions of 1.8 Gy per day (17 fractions) 5 days a week With Concomitant chemotherapy including Capecitabine 1600 mg/m²/day, five days a week.

PROCEDURE

Surgery

Surgery will be performed at: * Arm A: 8 weeks (±1) after the end of treatment * Arm B: 6 weeks (±1) after the end of treatment Surgical procedures are defined into three categories: * Total mesorectal excision (TME) * Extended-TEM (e-TME) * Pelvic exenteration (PE)
