Treatment: Surgery: Surgical Resection
Surgery is to be performed according to the standard procedure for locally advanced rectal cancer 4 to 6 weeks after completion of the integrated preoperative radiotherapy with FOLFOX chemotherapy regimen.

Summary
Brief summary
The aims of the trial are (1) to determine the tolerability rate in the setting of a
multi-centre study and (2) to determine secondary tolerability endpoints, toxicity rates and
