[Problems of evaluation concerning the success achieved by treating the mastocarcinoma (author's transl)]

The authors analyze the differences of the figures of success communicated in literature for the curative treatment of the mastocarcinoma. They find that neither the therapy method nor the extension of the operated body region are decisive for these figures. The individual success depends on the stage, and the group result is only influenced by the composition of the patients; These observations explain also why the figures of success of the curative therapy of the mastocarcinoma which were based on the stages of the disease have been at a standstill since 25 years. A decisive improvement, however, can be anticipated by virtue of an intensified prevention of mastocarcinoma and a changement of the therapy conception including a prophylaxis against metastases.
