LARS Study

Protocol summary

The purpose of this study is to evaluate the degree of low anterior resection syndrome manifested in patients with cancer treated in the pelvic area (rectal and anal canal) and that were treated with surgery alone (low anterior resection and subsequent ileostomy reversal), or with pre-operative radiation therapy (external beam radiotherapy combined with chemotherapy or brachytherapy), followed or not by low anterior resection and a subsequent ileostomy reversal. The purpose of the study is to also evaluate the bowel function deterioration based on age, by comparing the above population to a general cancer patient population.
