4.1.2. Clinicopathological and Tumor Serum Marker Profile of the EOC and NEOC Groups

In the whole group, 19 of 47 (40%) patients belonged to the EOC group and 28 patients (60%) belonged to the NEOC group.

Cases included in the EOC group were characterized by the presence of associate endometriotic lesions consisting of the endometriosis area in the form of an endometriotic cyst lined with endometrial epithelium and endometrial stroma, as well as evidence of hemosiderin deposits and chronic hemorrhage or proliferative endometriosis foci with a well-developed glandular profile.

The mean age of patients was 59.10 ± 8.66 years in the EOC group and 56.57 ± 2.64 years in the NEOC group. The EOC group comprised the following histological types: COC—4 cases; HGSC—3 cases; HGEC—8 cases; mixed tumors—4 cases; and none of LGSC, LGEC, MOC, or undifferentiated carcinoma cases were classified as EOC. The histological types in NEOC group were: LGSC—4 cases; LGEC—5 cases; COC—5 cases; HGEC—3 cases; MOC—5 cases; HGSC—5 cases; and undifferentiated—1 case. The median value of the preoperatory CA 125 level in the EOC group was 1201.5 U/mL, while a median value of 101 U/mL was found in the NEOC group.
