Abstract

Objective: The aim of this study is to determine the expression of the immunohistochemical markers with recpect to the histologic grade and lymph node metastasis in breast carcinomas. Methods: We studied 35 cases, distributed as 32 invasive ductal carcinoma, 1 invasive papillary carcinoma, 1 invasive lobular carcinoma and 1 atypical medullary carcinoma. Paraffin sections were immonhistochemically stained with S-100, Vimentin, Sitokeratin (6 and 64 kd M.W, polyclonal) and HMB 45 using immunoperoxidase technique. Results: Immunhistochemical results were as follows; S 100 positivity in 16 cases (45,7%) Vimentin positvity in 13 cases (37%) Cytokeratin positivity in 12 cases (34%) and HMB-45 positivity in 12 cases (34%). Vimentin expression exhibited no correlation, between histologic grade and lymph node metastasis. Although there was no significant difference, between Cytokeratin and S-100 positivity with respect to histologic grade. We observed few axillary lymph node metastasis in those cases (P<0.05). We did not observe significant difference between HMB-45 + and &#8211; for histologic grade, but in HMB-45 positive cases more axillary lymph node metastasis were evaluated according to negative cases (P<0.05). Conclusion: While our results with S-100 and Vimentin were in concordance with the literature, we found higher degree of HMB-45 expression compared to the previous reports.

Özet

Amaç: Bu çalışmada meme karsinomu olgularında; immün belirleyicilerin ekspresyonu ile tümörlerde histolojik derece ve aksiller lenf nodu metastazı arasındaki korelasyonu araştırmak amaçlanmıştır. Yöntem: 32. invaziv duktal karsinom, 1. invaziv papiller karsinom, 1 invaziv lobüler karsinom ve 1 atipik medüller karsinom olmak üzere toplam 35 meme karsinomu olgusu incelenmiştir. Formalinle fikse edilmiş ve parafine gömülmüş dokulardan alınan kesitlere S-100, vimentin, sitokeratin (56 ve 64Kd molekül ağırlığında poliklonal), HMB-45 immünoperoksidaz yöntemi ile immünohistokimyasal boyama yapılmıştır. Bulgular: Olgularımızda immünohistokimyasal sonuçların dağılımı şöyledir. S-100 16 olguda (% 45.7), Vimentin 13 olguda ( % 37) , Sitokeratin 12 olguda ( % 34), HMB-45 12 olguda (% 34) pozitif olarak tespit edilmiştir. Vimentin ekspresyonu ile histolojik derece ve aksiler lenf nodu metastazı arasında korelasyon izlenmemiştir. Sitokeratin ve S-100 pozitifliği ile histolojik dereceler arasında anlamlı bir fark bulunmazken, bu olgularda lenf nodu metastazının daha az olduğu gözlenmiştir (P<0.005). HMB45 + ve – olgularda tümörlerin histolojik dereceleri arasında anlamlı bir fark olmadığı fakat + olgularda aksiller lenf nodu metastazının daha yüksek oranda gözlendiği tespit edilmiştir (P<0.005). Sonuç: Vimentin ve S-100 ile ilgili sonuçlarımız literatürle uyumlu olurken , HMB-45 ekspresyonu daha önce bildirilen çalışmalara göre belirgin olarak yüksek bulunmuştur.
