Methods: The University of Iowa Cancer Registry was queried to identify all patients with stages II–III rectal cancer who received nCRT and surgery from 2000 through 2012. Primary endpoints were time interval to surgery (TI), and overall survival (OS). Secondary endpoints included pathologic outcomes, perioperative morbidities and postoperative complications. Patient characteristics and treatment regimens were compared. Univariate Cox proportional hazard models were used to study the association between TI and OS. Associations of TI with secondary endpoints were tested using Chi-square tests of association. Results: Eighty-seven patients presented with stages II–III rectal cancer. Mean TI was 9.92 weeks. There was no significant association between TI and OS when comparing Conclusions: OS was not influenced by longer intervals between nCRT and surgery. Delaying surgery beyond 8 weeks was associated with increased risk for wound infection. UR - https://jgo.amegroups.org/article/view/27585
