Abstract

Objective: The most important predictive parameter for the biological behavior of urothelial carcinomas except depth of invasion is the histological grade of the tumor. However, crucial discordances arise between pathologists because of subjectivity in histological grading schemes and these discordances cause difficulties especially in lowgrade tumors. The number of studies aiming to predict the risk of recurrence and progression in urothelial carcinomas has therefore increased in recent years. Our aim in this study was to evaluate the relation of histopathological and clinical characteristics of urothelial carcinomas with proliferation and apoptosis markers and to determine predictive parameters for their biological behavior.Material and Method: This study included 84 previously diagnosed cases of urothelial carcinoma of the urinary bladder. Immunohistochemical expressions of Ki-67, p53, Bcl-2, and Bax were examined in each case.Results: Expressions of Ki-67 and p53 determined a significant relationship between pathological stage and histological grade of the cases. There was no significant relationship between the other apoptotic markers (Bcl-2, and Bax) and clinical or morphological parameters.Conclusion: We concluded that the evaluation of Ki-67 and p53 expression combined with pathological stage and histological grade may give more accurate information about the biological behavior of urothelial carcinomas of the urinary bladder.

Özet

Amaç: Ürotelyal karsinomlarda invazyon özelliği dışında, bu tümörlerin biyolojik davranışlarını önceden tahmin etmemizi kolaylaştıracak en önemli parametre, tümörün histolojik derecesidir. Ancak histolojik derecelendirme modellerinde, subjektiviteye açık oluşları nedeniyle patologlar arasında ciddi uyumsuzluklar ortaya çıkmakta ve özellikle düşük dereceli tümörlerde bu uyumsuzluk sorun oluşturmaktadır. Bu nedenle, ürotelyal karsinomların rekürrens ve progresyon risklerini öngörmeye yönelik olarak farklı parametre arayışları son yıllarda artarak sürmektedir. Bu çalışmada amacımız, ürotelyal karsinomlarda morfolojik ve klinik verilerle hücre proliferasyonu ve apoptozis ilişkili belirleyiciler arasındaki korelasyonu araştırarak tümörlerin biyolojik davranışına yönelik parametreler ortaya koymaktır.Gereç ve Yöntem: Histopatolojik olarak değerlendirilerek mesanede ürotelyal karsinom tanısı almış 84 olgu çalışmaya alınmıştır. Her olguda immünhistokimyasal yöntemle Ki-67, p53, Bcl-2 ve Bax ekspresyonları değerlendirilmiştir.Bulgular: Olguların patolojik evre ve histolojik derecesi ile Ki-67 ve p53 ekspresyonları arasında anlamlı ilişki olduğu saptanmıştır. Diğer apoptotik belirleyiciler ile klinik ve morfolojik parametreler arasında anlamlı ilişki gözlenmemiştir.Sonuç: Ürotelyal karsinomlarda patolojik evre ve histolojik derece ile Ki-67 ve p53 ekspresyonunun kombine edilerek değerlendirilmesinin tümörün biyolojik davranışı konusunda daha doğru bilgi verebileceği sonucuna varılmıştır.
