Abstract

Objective: Despite of their similar microscopic findings. Fibromatoses are divided into two groups as superficial fibromatoses and deep fibromatoses, which have different immunohistochemical profiles and clinical characteristics Our aim was to evaluate the expressions of ER-a, ER-b, b-catenin, EGFR, CD117, p53, Ki-67 and mitotic rate in superficial and deep fibromatoses.Methods: Thirty-seven cases consisting of 15 superficial and 22 deep fibromatoses were reevaluated as regards ER-a, ER-b, b-catenin, EGFR, CD117, p53 expressions, Ki-67 proliferative index and the mitotic rate. Two groups were compared statistically and discussed.Results: ER-a expression was not observed in any case. ER-b and b-catenin expressions were more intense in the deep fibromatoses group. The ER-b intensity, b-catenin expression, Ki-67 proliferation index and mitotic rates were statistically significantly higher in the deep fibromatoses group (p=0.04, 0.01, 0.001, 0.001 respectively). There was no statistically significant difference in CD117, EGFR, and p53 expressions between groups.Conclusion: ER-b intensity, b-catenin and Ki-67 expression rates and the mitotic index were statistically significantly higher in the deep fibromatoses group in our study. We suggest that these markers may have predictive value in determining the course of the lesions

Özet

Amaç: Fibromatozisler benzer mikroskobik bulgulara sahip olmasına rağmen, farklı immünohistokimyasal profileri ve klinik özellikleri nedeniyle yüzeyel ve derin fibromatozisler olmak üzere iki gruba ayrılırlar. Amacımız yüzeyel fibromatozisler ve derin fibromatozislerde ER-a, ER-b, b-katenin, EGFR, CD117, p53, Ki-67 ekspresyonlarını ve mitotik oranlarını değerlendirmek.Yöntemler: ER-a, ER-b, b-katenin, EGFR, CD117, p53, Ki-67 ekspresyonları ve mitotik oranları 15 yüzeyel, 22 derin fibromatozisi içeren 37 olguda yeniden değerlendirildi, iki grup istatiksel olarak karşılaştırıldı ve tartışıldı.Bulgular: ER-a ekspresyonu hiçbir olguda izlenmedi. ER-b ve b-katenin ekspresyon şiddeti derin fibromatozis grubunda daha yüksek idi. ER-b ekspresyon şiddeti, b-katenin ekspresyonu, Ki-67 proliferasyon indeksi ve mitotik oranlar derin fibromatozis grubunda istatistiksel olarak anlamlı düzeyde yüksekti (sırasıyla; p=0,04, 0,01, 0,001, 0,001). Yüzeyel ve derin fibromatozis grupları arasında CD117, EGFR ve p53 ekspresyonlarında istatiksel olarak anlamlı fark saptanmadı.Sonuç: Çalışmamızda ER-b ekspresyon şiddeti, b-katenin ekspresyonu, Ki-67 proliferasyon indeksi ve mitotik oranı derin fibromatozis grupunda anlamlı olarak yüksek bulundu. Kabul tarihi: 17.12.2015 Biz bu belirteçlerin, hastalığın gidişatını belirlemede bir öngörü değeri olabileceğini düşünmekteyiz
