Abstract

Aim: The aim of this study was to help identify new prognostic markers in renal cell carcinomas (RCC), to show the role of autophagy in the pathogenesis of RCC and to shed light on new treatment modalities in RCC. Material and Methods: Clinicopathological stages, tumor necrosis and microvascular invasion (MVI) were determined retrospectively and Beclin-1, Ki-67, and p53 were studied immunohistochemically. Results: Tumor necrosis, MVI, Ki-67, and p53 in RCCs were positively correlated with Fuhrman nuclear grade and pathologic tumor stage, while Beclin-1 was only associated with nuclear grade. MVI and Ki-67 were associated with distant organ and lymph node metastasis. Ki-67 and necrosis correlated positively with p53 and Beclin-1 expression, but not with MVI. Beclin-1 were positively correlated necrosis, but not with p53 and MVI. p53, Ki-67 and MVI were negatively correlated with survival, while the effect of Beclin -1 and necrosis on survival couldn’t be demonstrated. Conclusion: Ki-67, p53, and MVI in RCCs are prognostic parameters with effects on survival. Although Beclin-1 was not a prognostic parameter associated with survival, its expression in tumor tissue was found to be increased. At the same time, there is less staining in non-tumor renal parenchyma. Beclin-1 is a marker of autophagy and is thought to be involved in RCC pathogenesis rather than its prognostic significance.

Özet

Amaç: Bu çalışmanın amacı böbrek hücreli karsinomlarda (BHK) yeni prognostik belirteçlerin belirlenmesine yardımcı olmak, otofajinin BHK patogenezindeki rolünü göstermek ve BHK'daki yeni tedavi yöntemlerine ışık tutmaktır. Gereç ve Yöntemler: Klinikopatolojik evreler, tümör nekrozu ve mikrovasküler invazyon (MVI) retrospektif olarak belirlendi ve Beclin-1, Ki-67 ve p53 immünohistokimyasal olarak incelendi. Bulgular: BHK’larında tümör nekrozu, MVI, Ki-67 ve p53; Fuhrman nükleer derece ve patolojik tümör evresi ile pozitif korelasyon gösterirken, Beclin-1 sadece nükleer derece ile ilişkiliydi. MVI ve Ki-67, uzak organ ve lenf nodu metastazı ile ilişkiliydi. Ki-67 ve nekroz, p53 ve Beclin-1 ekspresyonu ile pozitif koreleydi ancak MVI ile korele değildi. Beclin-1 nekroz ile koreleydi, ancak p53 ve MVI ile korele değildi. p53, Ki-67 ve MVI sağkalım ile negatif korelasyon gösterirken Beclin -1 ve nekrozun sağkalım üzerindeki etkisi gösterilemedi. Sonuç: BHK’larda Ki-67, p53 ve MVI sağkalım üzerine etkileri olan prognostik parametrelerdir. Beclin-1, sağkalım ile ilişkili bir prognostik parametre olmamasına rağmen, tümör dokusunda ekspresyonunun arttığı bulundu. Aynı zamanda, tümör dışı böbrek parankiminde daha az boyama vardır. Beclin-1, otofajinin bir belirtecidir ve prognostik öneminden ziyade BHK patogenezinde rol oynadığı düşünülmektedir.
