[Metastatic pleural effusions from MAMMA carcinoma (author's transl)].

43,7% of 1262 pleural effusions investigated between 1958 to 1975 proved to be malignant. In females the malignant effusions caused by mamma carcinoma ranged at the first place. The diagnostic and therapeutic possibilities were studied in 60 cases of these effusions. For etiological diagnosis the criteria of clinical findings, chemical parameters and cytology proved to be important. Cytostatic treatment was more effective in cases of mamma carcinoma than in other tumours of the thoracic organs.
