Risk adjustment as basis for rational benchmarking: the example of colon carcinoma.

Background: The results of resection of colorectal carcinoma can vary greatly from one hospital to another. However, this does not necessarily reflect differences in the quality of treatment. The purpose of this study was to compare various tools for the risk-adjusted assessment of treatment results after resection of colorectal carcinoma within the context of hospital benchmarking.

Feasibility and accuracy of TRUS in the pre-treatment staging for rectal carcinoma in general practice.
