[Computer-supported after-care system for patients with tumors using a cancer-register]

A computerized follow-up system for patients with malignant tumors is described. This system is in use in the "Chirurgische Klinik der Universitat Munster" and in the "Fachklinik Haus Hornheide". As a special service to these clinics a central cancer registry furnishes periodically lists of patients. These lists are used as surveys of treated cancer patients. It is possible to contact those patients by letter, who do not present themselves for clinical examination. Goals of the system are the documentation of the course of disease, the analysis of survival and the follow-up of the patients. Thus, the clinics manage a comprehensive cancer care program with a minimum lost of contact.
