PURPOSE: To identify the risk factors for perioperative morbidity in patients undergoing resection of primary rectal cancer, with a specific focus on the effect of neoadjuvant therapy. METHODS AND MATERIALS: This exploratory analysis of prospectively collected data included all patients who underwent anterior resection/low anterior resection or abdominoperineal resection for primary rectal cancer between October 2001 and October 2006. The study endpoints were perioperative surgical and medical morbidity. Univariate and multivariate analyses of potential risk factors were performed. RESULTS: A total of 485 patients were included in this study; 425 patients (88%) underwent a sphincter-saving anterior resection/low anterior resection, 47 (10%) abdominoperineal resection, and 13 (2%) multivisceral resection. Neoadjuvant chemoradiotherapy was performed in 100 patients (21%), and 168 (35%) underwent neoadjuvant short-term radiotherapy (5 x 5 Gy). Patient age and operative time were independently associated with perioperative morbidity, and operative time, body mass index >27 kg/m(2) (overweight), and resection type were associated with surgical morbidity. Age and a history of smoking were confirmed as independent prognostic risk factors for medical complications. Neoadjuvant therapy was not associated with a worse outcome. CONCLUSION: The results of this prospective study have identified several risk factors associated with an adverse perioperative outcome after rectal cancer surgery. In addition, neoadjuvant therapy was not associated with increased perioperative complications.
