Prognostic factors in metastatic breast cancer.

Abstract

Modern polychemotherapy has decisively changed the spontaneous course and median survival in metastatic stages of breast cancer. The prognosis for patients with the rather unfavorable type of visceral metastatic spread is definitely better now than 10 years ago. The influence of modern polychemotherapy on the survival and course of cases with mainly osseous metastases, however, is more limited. It seems that, in contrast to hormonal therapy, modern polychemotherapy alters the course of more aggressive types of metastases with a poor prognosis into a more favorable form of disease.
