Objective: To determine the role of routine cervical Pap smears in detecting endometrial carcinomas.
Method: A retrospective study was carried out from the histopathology archives for cases diagnosed as endometrial carcinomas with Pap smears within 6 months before histological diagnosis. The demographic details, reports of Pap smears and other tumor parameters on histopathology were noted.
Results: We identified 380 of 482 cases of endometrial carcinoma with a documented Pap smear within 6 months before histopathogical diagnosis. Out of 380 cases, 187 cases (49.2%) had shown abnormalities on Pap smear of which 80 cases (42%) were diagnosed as atypical glandular cells and 78 cases (41.7%) were diagnosed as adenocarcinoma. The presence of glandular abnormality on Pap smear significantly correlated with the tumor type, myometrial invasion and cervical involvement on histopathology (P < .05). Cases which had higher FIGO staging also had a higher detection rate on Pap smear (P < .05).
Conclusion: The Pap smear may help in detection of endometrial carcinoma especially in cases with type 2 endometrial carinomas, tumor with cervical involvement and/or advanced FIGO stage.
Keywords: atypical glandular cells; cervical involvement; endometrial carcinoma; myometrial invasion; pap smear.
