Between November 1998 and October 2000 bone marrow aspirations were taken from 60 patients with primary ovarian carcinoma. The aspirations were assayed for cytokeratin-positive and u-PA-R(CD87)-positive cells after a double-immunfluorescence staining. After the detection of cytokeratin-positive cells in bone marrow a u-PAR-quantification via laser scan microscopy was performed. Before the begin of the therapy 7 out of 30 (23 percent) patients, after the primary chemotherapy 6 out of 21 (28 percent) patients were identified with cytokeratin-positive cells in bone marrow. A significant deviance was detected between cytokeratin-positive cells and stage of FIGO-stadium, stage of pT-stadium, elevation of tumor marker CA 12-5 i.s. and grading. Furthermore the study shows that the intensity of u-PA-receptor on cytokeratin-positive cells is associated with progression free survival. No correlation was found between the detection of cytokeratin-positive cells in bone marrow and the course of the disease.
