Analysis of the quality of care for colorectal cancer is an essential foundation for further development and is based on the comparison of the goals set and the actual quality of care. This publication presents the reality of care in the State of Brandenburg covering the complete spectrum of treating clinics based on the data of the clinical cancer register. This study analyzed the number of resected and examined lymph nodes, the quality of total mesorectal excision (TME), the residual tumor (R0) resection rate and the proportion of adjuvant therapy of colon cancer in Union internationale contre le cancer (UICC) stage III depending on the operation quota of hospitals and the certification as bowel cancer center according to Onkozert. Apart from the R status, the analyses showed no differences in the qualitative operation data from the clinical cancer register depending on the hospital volume., (© 2021.

Background: The aim of this study was to evaluate the incidence and risk factors associated with anastomotic leakage after colon cancer surgery using data compiled in the nationwide German qualitative multi-center study "Colon/Rectum Cancer" (WGCRC)., Methods: From 01/01/2000 to 12/31/2004 data recorded from patients with anastomotic leakages were evaluated to determine independent predictors of leakage using logistic regression analysis., Results: A total of 28,271 patients underwent colon resection with anastomoses and anastomotic leaks occurred in 3.0% (n=844). Multivariate analysis identified long duration of surgery, a high ASA score, male gender, obstruction, left-sided tumor, cardiovascular hepatic comorbidity, single-layer hand suture, anastomoses using the biofragmentable Valtrac ring, intraoperative complications and BMI>30 kg/m(2) as risk factors for postoperative occurrence of anastomotic leakage., Conclusions: Even though the rate of anastomotic leaks in patients with anastomoses after resection for colon cancer is low, it remains a significant complication, associated with significant morbidity and mortality. The knowledge of risk factors should be considered in perioperative decision-making regarding anastomotic technique and indications for Hartmann's procedure.

Background: Using data and analysis compiled in the nationwide German Colon/Rectal Cancer qualitative multicenter study, the aim of this study was to determine the value of laparoscopic surgery for colon cancer in clinical routine., Methods: From 1 January 2000 to 31 December 2003, patients with colon cancer resections were evaluated for short-term postoperative and long-term oncologic results associated with operative approach (laparoscopic vs conversion vs open)., Results: Of 21,721 patients with colon cancer, 949 (4.4%) underwent laparoscopic resection. These patients were younger (P<0.001) with lower ASA risk factors (P<0.001) and earlier UICC tumor stages (P<0.001) than open resected patients. They also showed reduced overall morbidity (P<0.001), in-hospital mortality (P=0.001), and shorter hospital stays (P<0.001). The rates of intraoperative and specific complications remained unchanged. Nineteen percent of the patients had resections converted to open approaches. These had the highest overall morbidity and longest hospital stays. Their mortality was three times that of the group with complete laparoscopic resection., Conclusions: The open approach remained the standard of surgical care in colon cancer for the study duration. Laparoscopic surgery was used in only a small number of patients. By virtue of preferential patient selection, better early postoperative and long-term results could be achieved for the laparoscopic group than with the open approach. Conversions were shown to be associated with inferior results at the high rate of 19%. To ensure optimal results, laparoscopic surgery for colon carcinoma should be conducted by an experienced surgeon in an appropriately selected patient pool.
