Optimal Surgery and MRI Based Radiochemotherapy in Rectal Carcinoma (OCUM)

October 18, 2016 updated by: Theo Junginger, Johannes Gutenberg University Mainz

Optimal Surgery With Total Mesorectal Excision and MRI Based Multimodal Therapy of Rectal Carcinoma

The objective of the study is to provide proof that a MRI based preoperative radiochemotherapy in patients with locally advanced rectal carcinoma allows limiting RCT to high risk patients without increase of locoregional recurrence rate and decrease of overall survival provided there is a high quality of mesorectal excision.

Detailed Description

The criteria for application of RCT is the distance of the tumor from mesorectal fascia in preoperative MRI of the pelvis. In case of a T 4 tumor or a tumor with a distance of 1mm of less form mesorectal fascia long-course radiochemotherapy is applied followed by surgery, in all other cases primary surgery is done.
