Abstract

İM :To research PTEN expression in A endometrial adenokarsinom and todetermine its clinical importanceIn ourstudy;50 subjects who underwent radical surgery because of endometrium cancer and whoseoperational materials are evaluated in 1999-2006 in our clinic were included.The cross sections prepared by choosing the most descriptive block for each subject were applied anti-PTEN special paint with immunohistochemical methodIn accordance with anti-PTEN paint applied with immunohistochemical.Method to preperations of subjects;The subjects in whom no coloration was determined or coloration less than %50 was determined were accepted as loss of PTEN protein expression,and the ones in whom coloration more than %50 was determined were considered normal in terms ofPTEN expression In the 50 endometrial cancer subject whom we investigated,we didn't find statistically meaningful correlation between PTEN expression and age,histological level,surgery stage andmyometrial invasion.However,in early stagetumours,lower tumour level,restricted tumours in endometrium without myometrial invasion; we observed that PTEN expression was higherFinally,there is no molecular sign in routine clinical use for endometrium cancer nowadays. Although PTEN is a tumour reducing gene product,its importance in endometrial adenocarsinom and its place in determining prognosis are stilcontroversial. The determination of molecularsigns which make genetic changes in cancerous cells can guide in early diagnosis,survival and determination of recurrance. The revealation of the roles of molecules and signal ways in the signal transfer such as PTEN and Act path incarsinogenesis and the development of inhibitoragents specific to these ways can enable new horizons to be broadered in teratment ofendometrial cancer.

Özet

Endometriyal adenokarsinomlarda PTEN ekspresyonunuaraştırmak ve klinik önemini belirlemektir. Çalışmamıza kliniğimizde 1999-2006 yılları arasında endometriyumkanseri nedeni ile radikal cerrahi operasyon uygulanan ve Patoloji kliniğinde operasyon materyalleri değerlendirilen 50 olgu dahil edildi. Her olgu için en tanımlayıcı blok seçilerek hazırlanan kesitlere İmmünhistokimyasal yöntem ile anti-PTEN özel boyasıuygulandı.Olguların preparatlarına immünhistokimyasal yöntem ile uygulanan anti-PTEN boyasına göre; boyanma saptanmayan ve %50'den az boyanma saptanan olgular PTEN protein ekspresyon kaybı olarak, %50'den fazla boyanma saptanan olgular PTEN ekspresyonu açısından normal kabul edildi.Araştırdığımız 50endometriyal kanser olgusunda PTEN ekspresyonu ile yaş, histolojik tip, histolojik derece, cerrahi evre ve myometriyal invazyon arasında istatistiksel olarak anlamlı ilişki saptamadık. Ancak erken evre tümörlerde, düşük tümör derecesinde ve myometriyal invazyonu o l m a y a n ,e n d o m e t r i y u m d as ı n ı r l ıt ü m ö r l e r d eP T E Nekspresyonunun daha yüksek olduğunu gözlemledik.Sonuç olarak, günümüzde endometriyum kanseri için rutin klinik kullanımda olan moleküler bir belirteç yoktur.PTEN, tümör baskılayıcı bir gen ürünü olmakla beraberendometriyal adenokarsinomlardaki önemi ve prognozubelirlemedeki yeri halen tartışmalıdır. Kanser hücrelerinde genetik değişiklikler yapan moleküler belirteçlerin saptanması erken tanı, sağkalım ve nüksü belirlemede rol gösterici olabilir. PTEN ve Akt yolağı gibi sinyal iletiminde yer alan moleküllerin ve sinyal yollarının karsinogenezdeki rollerinin ortaya konması, bu yollara özgül inhibitör ajanların geliştirilmesi endometriyal kanser tedavisinde yeni ufukların açılmasını sağlayabilir.
