Abstract
The National Cancer Institute (NCI) Consensus Conference concluded in 1990 that chemotherapy plus concurrent radiation (chemoradiation) was the standard postoperative adjuvant treatment for all patients with pT3 and/or N1-2 rectal cancer [1]. This recommendation was based on phase III trials that compared postoperative chemoradiation arms with control arms of either surgery alone or surgery plus postoperative irradiation (Mayo/NCCTG 79-47-51) and demonstrated improvements in both disease-free and overall survival [2]. The standard design in US trials was to deliver six cycles of bolus 5-fluorouracil (5-FU)–based chemotherapy; concurrent irradiation was also given during cycles 3 and 4.
