Endometrial hiperplazi ve adenokarsinomlarda progesteron reseptörlerinin durumu

Amaç: Bu çalışmada endometrial hiperplazi ve endometrial adenokarsinom teşhisi konulmuş vakalarda endometriumdaki östrojen reseptörlerinin (ER) özelliklerini karşılaştırmayı amaçladık. Yöntem: Basit tipte endometrial hiperplazi tanısı almış 15 vaka ile iyi diferansiye (greyd I) endometrial adenokarsinom tanısı almış 15 vakada peroksidaz-antiperoksidaz metodu ile parafin blok kesitlerine spesifik fare monoklonal ER antikorları uygulandı ve dokulardaki ER'leri araştırıldı. Bulgular: ER'lerin spesifik boyanması sadece çekirdekte sınırlı idi; sitoplazmada boyanma tespit edilmedi. Endometrial hiperplazi vakalarının tamamında epitel hücrelerinin çekirdeklerinde ER pozitifliği mevcut iken bu oran endometrial adenokarsinom vakalarında % 80 olarak bulundu. Her iki grupta da stromal hücrelerde epitel hücrelerine göre daha düşük derecede ER pozitifliği mevcuttu. Sonuç: Endometrial adenokarsinom vakalarında steroid reseptörlerinin durumunun değerlendirilmesi hastaya uygulanacak tedavi yönteminin seçilmesine yandımcı olabilir.

Progesterone receptors in hyperplastic and carcinomatous endometria

Objective: The aim of this study was to compare characteristics of estrogen receptors (ER) in endometrium of cases of endometrial hyperplasia and adenocarcinoma. Methods: 15 cases with simple endometrial hyperplasia and 15 cases with grade I endometrial adenocarcinoma were evaluated. Specific monoclonal mouse antibody against estrogen receptor was used with peroxidase-antiperoxidase technique to localize estrogen receptors in paraffin embedded sections. Results: Specific staining for ER was limited to nuclei; no specific cytoplasmic staining was observed. ER was positive in the nuclei of epithelial cells in all of the patients with endometrial hyperplasia and in 80% of the patients with endometrial adenocarcinomas. In both groups, ER was less positive in the nuclei of stromal cells than in the nuclei of epithelial cells. Conclusion: Evaluating estrogen receptors in the cases of endometrial adenocarcinoma can be helpful for selecting treatment method.
