Abstract: This thesis focuses on quality assurance of rectal cancer treatment, in particular of the surgical treatment. Both oncological short-term and long-term outcome parameters are studied, but also other end-points which are important for quality assurance are investigated, such as anastomotic leakage and stoma reversal. The introduction of total mesorectal excision (TME) surgery resulted in an improved survival of patients with rectal cancer. However, survival of the elderly patients and patients treated with an abdominoperineal resection improved less. For frail elderly patients, postoperative mortality is an important competitive risk factor and other treatment schedules might be more appropriate. The abdominoperineal resection itself was associated with a nonradical resection, decreased local control and decreased survival compared to patients treated with a low anterior resection. To improve these results, in selected cases preoperative treatment should consist of chemoradiotherapy and/or a widened resection. Anastomotic leakage is a feared complication after colorectal surgery. After surviving this complication, the overall survival rate in the long-term is still reduced. However, oncological outcome was not significantly affected. The presence of a stoma resulted in a lower symptomatic leakage rate. 20% of stomas was never reversed. Standardised postoperative surveillance resulted in an earlier confirmation of the diagnosis anastomotic leakage.
