ABSTRACT
<p><b>OBJECTIVE</b>To study the diagnostic value of HNF-1β and Napsin A for ovarian clear cell carcinomas, serous carcinomas, endometrioid adenocarcinomas and metastatic Krukenberg tumors.</p><p><b>METHODS</b>Immunohistochemical EnVision method was used to detect the expression of HNF-1β and Napsin A in 38 cases of ovarian clear cell carcinoma, 30 cases of high-grade serous carcinoma, 22 cases of endometrioid adenocarcinoma and 16 cases of metastatic Krukenberg tumor. Expression of HNF-1β and Napsin A were compared, and sensitivity and specificity of clear cell carcinoma of the ovary were analysed.</p><p><b>RESULTS</b>The positive rate of HNF-1β in the ovarian clear cell carcinoma was 100%(38/38), higher than those in high-grade serous carcinoma and endometrioid adenocarcinoma (P<0.05), although significant difference was not observed from that of metastatic Krukenberg tumor (P>0.05). Napsin A expressed in 97.4% (37/38) of ovarian clear cell carcinoma, 6.7% (2/30) of high-grade serous carcinoma, 22.7% (5/22) of endometrioid adenocarcinoma. Napsin A expression in clear cell carcinoma was higher than those in high-grade serous carcinoma and endometrioid adenocarcinoma (P<0.01), and no expression of Napsin A was seen in metastatic Krukenberg tumor (P>0.05). The sensitivity and specificity of HNF-1β in the diagnosis of ovarian clear cell carcinoma were 100% and 52.9%, those of Napsin A were 97.4% and 91.2%, those of both HNF-1β and Napsin A were 97.4% and 91.2%, respectively. The sensitivity and specificity of HNF-1β or Napsin A in the diagnosis of ovarian clear cell carcinoma were 100% and 52.9%, respectively.</p><p><b>CONCLUSIONS</b>HNF-1β is a more sensitive marker for the diagnosis of ovarian clear cell carcinoma, whereas Napsin A is a more specific marker. The combined detection of HNF-1β and Napsin A may be helpful for the diagnosis of clear cell carcinoma of the ovary.</p>
