[Sclerosis and fibrosis of the bone marrow in lung and gastrointestinal tract cancers].

The authors analyzed the incidence of pathologic lesions of the bone marrow in the form of sclerosis and fibrosis in patients with lung and gastrointestinal tract (gastric, pancreatic, hepatic and bile duct) carcinomas. In the analysis of argentaffin and collagen fibres in the bone marrow we used Kundel's score modified by Bauermeister. The results obtained in the studied group were compared with the bone marrow of persons without neoplastic diseases and other disorders that might have affected the bone marrow. It was found that in patients with neoplastic disease and fibrosis of the bone marrow were quite frequent disturbances.
