RADİKAL PROSTATEKTOMİ SPESMENLERİNDEKİ VEGF’İN, E-CADHERİN’İN VE BIM’İN İMMÜNOHİSTOKİMYASAL EKSPRESYONLARININ PROGNOSTİK DEĞERİ

Abstract

Giriş: Bu çalışmanın amacı radikal prostatektomi spesmenlerindeki vasküler büyüme faktörü (VEGF), E-Cadherin ve Bim ekspresyonlarını değerlendirmek ve prognoz üzerine etkisini araştırmaktır.

Gereç ve Yöntem: Radikal prostatektomi uygulanan 66 hastanın (51 hasta pT2, 13 hasta pT3, 2 hasta pT4) spesmenleri VEGF, E-Cadherin ve Bim antikorları ile boyandı. VEGF, E-Cadherin ve Bim immünoreaktivite sonuçlarının Gleason skoru ve biyokimyasal nüks ile olan ilişkileri araştırıldı. İmmünohistokimyasal ve klinik verilere göre istatistiksel analiz yapıldı.

Bulgular: Hastalar Gleason skoruna (Gleson score <7 and Gleason ≥7) ve biyokimyasal nükse (PSA >0,2 ng/ml) göre gruplara ayrıldı. Gruplar arasında VEGF, E-Cadherin ve Bim ekspresyonlarında anlamlı fark olmamasına rağmen, biyokimyasal nüks saptanan hastalarda VEGF ekspresyonu %59,74 ve biyokimyasal nüks saptanmayan hastalarda %44,47 bulundu (p=0,058). Spearman korelasyon testi uygulandığında, VEGF ve E-Cadherin arasında anlamlı bir ilişki tespit edildi (p=0,05).

Sonuç: Tedaviye karar aşamasında yüksek riskli hasta grubunun belirlenmesinde kullanılabilecek biyobelirteçe henüz sahip değiliz. Düşüncemiz daha büyük sayılı çalışmalarda bu biyobelirteçlerin araştırılması ve immünohistokimyasal değerlendirmede imaj analiz yönteminin kullanılmasıdır.
