Chemotherapy Followed by Pelvic Reirradiation Versus Chemotherapy Alone as Pre-operative Treatment for Locally Recurrent Rectal Cancer

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.
