Comparative effectiveness in colon and rectal cancer

Abstract

Treatment of colorectal cancer is becoming more uniform, with wider acceptance of standardized guidelines. However, areas of controversy exist where the appropriate treatment is not clear, including: : should a segmental colectomy or a more extensive resection be performed in hereditary nonpolyposis colorectal cancer? : should an asymptomatic primary cancer be resected in the presence of unresectable metastatic disease? : what is the role of extended lymph node resection in colon and rectal cancer? : are there clinically significant benefits for a robotic approach to colorectal resection versus a laparoscopic approach? This chapter will examine these issues and discuss how they may be resolved.
