Der Chirurg als prognostischer Faktor in der onkologischen Chirurgie

The Surgeon(cid:29)s Impact on Outcome in Oncological Surgery. Outcome of cancer patients will be determined by the extend of disease as well as by the quality of treatment. Peri-operative morbidity and mortality usually serve as outcome measures in surgery. In addition, quality of oncological surgery will be indicated by local recurrence and survival rates and an estimation of quality of life as well. Several recent studies have found an inverse relationship between hospital volume and surgeon case load on the one hand and outcome on the other. These findings provide arguments in favor of regionalization of oncological surgery. Another argu-ment for a centralization is the increasing implementation of multimodal treatment protocols in cancer treatment. The present critical review summarizes data on this topic for the most common intestinal cancers.
