Abstract

Background/aims: Fascin is an actin-bundling protein that is important in cell motility. Fascin expression has been shown to have a potential role in tumor progression for some epithelial tumors. However, there are only a few studies related to its expression in mesenchymal tumors. We investigated fascin expression in gastrointestinal stromal tumors. Methods: Thirty gastrointestinal stromal tumors, which were very low (n=6), low (n=2), moderate (n=4), and high (n=18) risk, constituted our series. Immunohistochemical expression of fascin was studied in all cases. Results: Immunoreactivity was observed in only five cases, all of which were in the high-risk group. The remaining cases (25/30) showed no immunoreactivity, and the difference did not seem statistically important (p=0.261). Fascin expression was stronger in epithelioid cells than spindle-shaped cells (p=0.003). In addition, gastrointestinal stromal tumors in the small bowel showed higher fascin expression than those in the other localizations (p=0.043). Conclusions: It seems that anatomic localization and the tumor cell type of gastrointestinal stromal tumors show statistically significant differences with regard to fascin expression. Although our series is limited, we think that fascin should be considered as a marker that is worthy of further study for its potential usage as a prognostic indicator in gastrointestinal stromal tumors.

Özet

Amaç: Fascin, hücresel motilitede rol oynayan bir aktin desteleyici proteindir. Fascin ekspresyonunun bazı epitelyal tümörlerde, tümörün ilerlemesinde önemli rolü olduğu gösterilmiştir. Ancak, mezenkimal tümörlerdeki ekspresyonu hakkında çok az çalışma vardır. Bu çalışmada gastrointestinal stromal tümörlerdeki fascin ekspresyonu araştırılmıştır. Yöntem: Olgu serimiz çok düşük (n=6), düşük (n=2), orta (n=4) ve yüksek (n=18) risk grubunda bulunan toplam 30 gastrointestinal stromal tümör olgusundan oluşmaktadır. Bütün olgularda fascin ekspresyonu immünohistokimyasal yöntemle araştırılmıştır. Bulgular: İmmünoreaktivite yalnızca yüksek risk grubundaki beş olguda görülmüştür. Geri kalan olgularda (25/30) immünoreaktivite izlenmemiştir ve arada istatiksel olarak anlamlı fark bulunmamıştır (p=0.261). Fascin ekspresyonu, epiteloid görünümlü hücrelerde iğsi şekilli hücrelerden daha güçlü izlenmiştir (p=0.003). Ayrıca, ince bağırsak yerleşimli gastrointestinal stromal tümörlerde diğer yerleşim yerlerindekine oranla daha yüksek ekspresyon saptanmıştır (p=0.043). Sonuç: Gastrointestinal stromal tümörlerde tümörün anatomik yerleşimi ve tümör hücrelerinin görünümü ile fascin ekspresyonu arasındaki ilişki istatistiksel yönden anlamlı gibi görünmektedir. Olgu sayımız sınırlı olmasına rağmen, fascinin gastrointestinal stromal tümörlerde prognostik bir belirleyici olarak kullanılması amacıyla daha geniş kapsamlı çalışmalar için kayda değer bir belirteç olabileceğini düşünmekteyiz.
