MARKERS OF APOPTOSIS AND PROLIFERATION OF TUMOR CELLS IN THE DYNAMICS OF OVARIAN CANCER PROGRESSION

Antoneeva I.I., Petrov S.B.

83 ovarian cancer (OC) patients were immunohistochemically examined to determine the proliferation markers Ki-67 and PCNA as well as apoptosis markers p53 and bcl-2 in the primary tumor nodes. It was found that Ki-67 index was in average 5.4% on the Ist stage; 10.2% on the IInd stage; 47.0% on the IIIrd stage and 45.5% on the IVth stage of the disease. It was shown that in tumor progression the number of cells that express p53 or bcl-2 significantly increases. The conclusion is in the tumor progression in the primary tumor nodes there is a possible selection of p53+ neoplastic cells with high proliferative activity and hyperexpression of bcl-2 oncoprotein.
