Abstract

Objective: In colorectal carcinomas, tumor budding has been defined as the presence of isolated single tumor cells or small cell clusters in the stroma at the invasive tumor margin. In this study, the relationship between tumor budding density at the invasive tumor margin and pathological parameters is investigated. Material and Method: Haematoxylin and eosin stained slides of 73 cases with colorectal carcinoma were retrospectively evaluated for the presence and intensity of tumor budding by 2 observers. After the specimens were assessed, the highest density of tumor budding area was counted in a microscopic field of x200. Cases were separated into 2 groups according to tumor budding density as low grade (

Özet

Amaç: Kolorektal karsinomlarda tümör tomurcuklanması, invaziv tümör komşuluğundaki stromada bulunan izole tümör hücreleri ya da küçük tümöral hücre kümeleri olarak tanımlanmaktadır. Bu çalışmada kolorektal karsinomlarda invaziv tümör komşuluğundaki stromada bulunan tümör tomurcuklanması yoğunluğunun patolojik özelliklerle ilişkisi araştırılmıştır. Gereç ve Yöntem: Retrospektif olarak, kolorektal karsinomlu 73 olguya ait hematoksilen-eozin boyalı preparatlar tümör tomurcuklanması varlığı ve yoğunluğunun tespit edilmesi amacıyla 2 gözlemci tarafından değerlendirilmiştir. Preparatlar tekrar değerlendirildikten sonra tümör tomurcuklanmaları, en yoğun oldukları alan tespit edilerek x200 büyütme alanında sayılmıştır. Olgular, tümör tomurcuklanması yoğunluğu 10'dan az olanlar düşük dereceli, 10 ve üzeri olanlar yüksek dereceli olmak üzere 2 gruba ayrılmıştır. Bu grupların tümörün invazyon derinliği, histolojik derecesi, lenf nodu tutulumu ve vasküler invazyon gibi patolojik özelliklerle ilişkisi araştırılmıştır.Bulgular: Kolorektal karsinomlu 73 olgunun 33'ünde (%45,2) düşük, 40'ında (%54,8) yüksek dereceli tümör tomurcuklanması yoğunluğu tespit edilmiştir. Yüksek dereceli tümör tomurcuklanması yoğunluğu ile histolojik derece (p=0.042), lenf nodu tutulumu (p=0,0001) ve vasküler invazyon (p=0,0034) arasında istatistiksel olarak anlamlı ilişki saptanmıştır.Sonuç: Yüksek dereceli tümör tomurcuklanması yoğunluğu kolorektal karsinomlarda agresif fenotipik özelliklerle ilişkilidir.
