[Thrombocytosis and primary bronchial carcinoma. Study about 164 patients with bronchial carcinoma (author's transl)].

This paper is relating the study of 164 patients with primary and proved bronchial carcinoma. A thrombocytosis superior to 400,000/mm3 was observed in 36.6 p. cent of cases. But no statistic relation was found between the histological type of tumor, a biological inflammatory state, the existence of metastasis and thrombocytosis. However thrombocytosis was more frequently observed among anaemic and hyposideremic patients. No significantly changes of paO2 and paCO2 were noted in patients with thrombocytosis. The systematic platelet count could be of an interest in the interpretation of some thoracic radiography.
