The German experience: the surgeon as a prognostic factor in colon and rectal cancer surgery.

The data of the German prospective multicenter study of the Study Group for Colo-Rectal Carcinoma (SGCRC) were analyzed by uni- and multivariate methods with regard to surgeon-related prognostic factors. The parameters were frequency of intraoperative local tumor spillage, surgical volume, and department and surgical quality group. The results obtained from the data of the SGCRC implicate consequences for analyses and comparisons of therapy results and studies on adjuvant therapy in colon and rectal cancer.

[Comparative study of oncological outcome quality in colorectal carcinoma--ranking by surrogate endpoint?].

The data of the German Prospective Multicenter Study of the Study Group Colorectal Carcinoma (SGCRC) were analyzed with regard to interinstitutional differences in 5-year survival by statistical methods adequate for ranking and observing anonymity. Furthermore, possible so-called surrogate endpoints that allow an assessment of definite outcome after surgical treatment earlier than after 5 years were also analyzed. This requires a separate analysis for rectal and colon carcinoma patients.
