title: [Testing the resistance of human tumor and bone marrow cells to cytostatic agents].
abstract: Using a short term incubation cell culture method with incorporation of radioisotopes the effect of cyclophosphamide and adriamycin to carcinoma cells and at the same time to bone marrow cells of the same patients has been evaluated in vitro. Instead of cyclophosphamide, ineffective in vitro, 4-Hydroperoxycyclophosphamide was tested. In case of the tumor cells innate as well as drug-induced resistances are obtained in vitro. Different resistance behavior of tumor and bone marrow cells to cyclophosphamide and adriamycin may indicate therapeutic results to be expected in vivo. Simultaneous in vitro resistance testing of tumor and normal cells offers the possibility of better characterization of tumor and host.
