Surgical issues in rectal cancer: a 2004 update

Abstract

Rectal cancer is a major health concern in the United States, with an estimated 40,570 new cases diagnosed in 2004. There are 4 major goals in the treatment of a patient with rectal cancer: local control; long-term survival; preservation of anal sphincter, bladder, and sexual function; and maintenance or improvement in quality of life. Recent advances have been made in preoperative staging, local and radical surgical therapy, the importance of distal and circumferential resection margins, postoperative preservation of the anal sphincter mechanism and genitourinary function, and the role of laparoscopy in the treatment of these patients. Our aim is to outline some of the important surgical issues surrounding the management of patients with early-stage (T1/T2 N0) or locally advanced (T3/T4 and/or N1) rectal cancer.
