    Abstract:
    Serum CA125, CEA, AFP, LDH levels and LDH isoenzymes were analyzed in ovarian tumor patients, who were treated at Kyoto University Hospital. CA125 was positive in 10/16 (62.5%) cases of common epithelial carcinoma, especially 100% positive in serous carcinoma, but was negative in mucinous tumors. CA125 was also negative in patients with germ cell and sex cord stromal tumors. CEA was positive in 13/32 (40.6%) cases of epithelial carcinoma, most frequently elevated in patients with mucinous carcinoma, pseudomyxoma peritonei, and Krukenberg tumor. AFP was positive only in those with endodermal sinus tumors. LDH was elevated in 16/39 (41%) cases of epithelial carcinoma, but was not specific for histological types. In contrast, all 8 cases of dysgerminoma, 1 of immature teratoma and 2 of endodermal sinus tumor showed extremely elevated LDH levels. Moreover, the normal pattern or deviation to H subunit of LDH isoenzymes was seen in such cases of germ cell tumor, while deviation to M subunit was noted in epithelial and metastatic tumor patients. These data indicate that each parameter is useful as a tumor marker for the specific histological type of ovarian tumor; CA125 for non-mucinous epithelial carcinoma, CEA for mucinous tumor and Krukenberg tumor, AFP for yolk sac tumor, LDH and LDH isoenzymes for dysgerminoma and other solid germ cell tumors. In addition, preoperative diagnosis of histological types of ovarian tumors may be possible by combining these tumor markers.
