OBJECTIVE: To assess the immunohistochemical expression of BerEP4, a new epithelial antigen in ovarian cancer.
METHODS: We studied 62 cases of ovarian cancer in which BerEP4, CEA and CA-125 were investigated by an immunohistochemical method. We evaluated the correlations among immunohistochemical positivity and the grading, histotype and stage of disease.
RESULTS: BerEP4 was positive in 45 out of 62 cases (72.58%), CA-125 in 36 out of 62 cases (58.06%) and CEA in ten out of 62 cases (16.13%). BerEP4 was present both in serous and in mucinous tumors (80.96% vs. 80.77%). CA-125 was mainly expressed in serous vs mucinous tumors (66.67% vs. 57.69%). CEA was more prevalent in mucinous vs. serous tumors. Ber-EP4 was mainly expressed in G1 (75%) and G2 (77.27%). CA-125 was more present in G1 and G3 (both 62.50%) than G2 (50%), whereas CEA showed positivity in G1: 12.50%, G2: 22.73% and G3: 12.50%. There were no differences among the three antigens studied with regard to clinical stage.
CONCLUSIONS: In our study Ber-EP4 was positive in 45 out of 62 cases (72.58%) of primary epithelial ovarian cancers. The presence of this antigen seemed to be related to the histotype and grading but not to clinical stage.
