E.3 | Principal inclusion criteria |
- Histologically proven middle or low rectal carcinoma, ≤ 10 cm from the anal verge on MRI (sagittal slide) - cT3N0 and/or cT1-T3N+ on pretreatment imaging work up (pelvic contrast enhanced MRI and/or endorectal ultrasound), - Pretreatment predictive circumferential margin > 2mm on pretreatment imaging work up (pelvic contrast enhanced MRI) - Patients must be 18 years old or older - A World Health Organization (WHO/ECOG) performance status of 0 or 1 - Informed consent signed - Patients of childbearing / reproductive potential should use adequate birth control measures during the study treatment period and for at least 6 months after the last study treatment. A highly effective method of birth control is defined as those which result in low failure rate (i.e. less than 1% per year) when used consistently and correctly.
