Trial Information

The Randomised Study of Preoperative Radiotherapy and Local Excision for Radiosensitive Rectal Cancer


Local excision must involve all tissue invaded on pretreatment examination. For this reason,
4-5 tatoos of mucosa at the tumour border should be performed before the onset of treatment.
Next, the long-course radiochemotherapy or short-course radiotherapy is randomly allocated.
After 6 weeks interval, the full thickness local excision should be carried out with 1 cm
margin. Patients with good pathological response (complete response or downstaging to ypT1
disease)are followed up. Conversion to open surgery is offered to patients with poor
pathological response (ypT2-3 or positive margin). Close follow-up is carried out in order
to detect an early local recurrence either in a bowel wall or in mesorectal lymph nodes.
Rescue surgery is offered in patients with local recurrence.
