[Biological markers in cancer of the ovary].

The organism produces substances whose presence or amount indicate the existence of a neoplastic process, called biological tumor markers. They can be used in the clinical laboratory for diagnostic purposes, and also to orient about the evolution of the tumoral mass. There are about 90 tumor markers, 33 of them have studied in relation to cancer of the ovary, that are described in this work. Eight of them are the most important: CSAp, OCA, OCAA, IAP, Nagao's isoenzyme, hCG/hCG beta, hPL, and AFP.
