Local treatment for rectal cancer.

The treatment of rectal cancer includes both radical resection and local therapy. Radical resection remains the standard treatment, but is associated with increased morbidity and mortality, as well as the potential need for a temporary and occasionally, a permanent ostomy. The benefits of local treatment include a less invasive procedure with maintenance of bowel function and avoidance of a stoma. However, the efficacy of local treatment is now being challenged as the rates of recurrence after local excision alone appear to be much higher than previously thought. Although the primary goal of an oncologic resection is disease eradication, each case must be individualized to determine an optimal care plan.
