Preoperative Radiotherapy and Chemotherapy in Patients With Locally Advanced Rectal Cancer (PROArCT)

July 10, 2017 updated by: Trans Tasman Radiation Oncology Group

A Phase II Trial of Integrated Preoperative Radiotherapy and Chemotherapy With Oxaliplatin 5-FU and Folinic Acid in Patients With Locally Advanced Rectal Cancer

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 complete pathologic response rate in patients with locally advanced rectal cancer who are treated with an integrated preoperative radiotherapy with FOLFOX chemotherapy regimen.
