This probably necessitated an increased interval between chemotherapy and surgery (median 93 days in the Intergroup trial and 63 days in OE02 trial) with fewer patients completing the chemotherapy (71% compared to 90% in OE02 trial) and may have also impacted on the percentage of patients undergoing resection in the trial; 80.3% of patients in chemotherapy arm in the Intergroup trial proceeded to surgery as opposed to 92% in the MRC study
. The results from the OE02 trial led to neoadjuvant chemotherapy being widely accepted as standard of care.
