Based on the statement in the Gesundheitsprogramm des Ministeriums für Arbeit, Soziales und Gesundheit des Landes Sachsen-Anhalt 1997 (Health Program of the Ministry of Labour, Social Affairs and Health of the Federal State Sachsen-Anhalt), Sachsen-Anhalt is above the Germany average when comparing the general mortality on malignoms, it is investigated, at which tumour stage patients are being operated in average, and, if possibly higher tumour stages with a poorer prognosis at the start of a therapy would be a potential cause. Using the example of the colorectal cancer, which is one of the four most frequent solid tumours, a clinical-pathological analysis was carried out; this analysis investigated the tumour spreading at operation time, based on data of the Pathological Institut of the Martin-Luther-Universität Halle of years 1995 - 2000. The outcomes were compared with results of related investigations of other German tumour centres. The colorectal cancer appears more frequent at the age of 50 onwards. Men are operated more often than women, from the eight decade onwards women are predominant. In order to judge on the quality of the pathohistological diagnostic of tumour resectats quality parameters, published by Hermanek, have been proven to be useful. This means: in case the investigated quantities correspond to the parameters, then this is a proof of a high quality. The pathological tumour stage in the own evaluated data deviated only with respect to an increased pT3 portion comparing with the results of the other tumour centres. An increased mortality in colorectal cancer in Sachsen-Anhalt cannot be proven with this investigation.
