title: [The characterisation of malignant ovarian tumors by impulse cytophotometry (author's transl)].
abstract: 31 malignant adnexal tumors were investigated by impulse cytophotometry. From the DNS distribution curves we interpreted the positions and the height of the peaks in order to get informations about ploidy and proliferation pattern. 45.2% were classified into the diploid, 29.0% into the polyploid and 12.9% into the tetraploid group. 12.9% were aneuploid. Comparing our results with chromosome analyses in the literature we found more tetraploid tumors in our material. For our polyploid curves we assume, that many of the cells in the 8c-peak remain in the corresponding G2'-Phase, not undergoing mitosis.
