The pathohistological types of tumors were different. The age of the patients ranged from 20–83 years. In all patients the value of biochemical marker CA125 was determined. The aim of this study was to determine the usefulness of CA125 measurement in different age groups and in different patohistologycal forms of tumor. CA125 has proven to be positive in 89.1% of women with ovarian cancer and in 62% with neoplasm of low malignant potential.
