[Options for quality improvement in the treatment of rectum carcinoma].

By means of a prospective multi centre study, 13 419 cases of surgically treated patients with rectum carcinomas were registered between 1.1.2000 and 31.12.2003 and assessed in regard to possible problems concerning indications and operative procedures. Beside a high rate of non-local resective procedures in T1-low risk carcinomas, unnecessary extirpations in cases of tumour localisation over 8 cm from the anal verge were found. Tumours of the lower two-thirds of the rectum were treated by incomplete TME in 20 % of the patients. In addition, there seems to be too low a rate of neo-adjuvant therapy procedures. Protective stomata were frequently foregone after low anterior resection. Endoscopic interventional methods were still used reluctantly in inoperable situations.
