Abstract

Objective: Breast cancer is the second most common cancer after lung cancer and is about 26% of all cancers in women. Mortality rate is 18%. Imaging methods, aspiration cytologies and core biopsies are useful before radical surgeries are performed. Breast carcinomas have different histopathologic features. The reason for these different histopathologic features are the increased number of investigations on the genetic characteristics of the tumor, and research the gene expression patterns in tumors. The melanoma-associated antigen (MAGE) family consists of a number of antigens recognized by cytotoxic T lymphocytes. MAGE–A11 is expressed in tumors such as melanoma, breast and lung cancer. In this study we investigated MAGE–A11 expression in invasive carcinoma of no special type, invasive lobular carcinomas and benign breast tissues. Material and Method: A total of 150 cases as 50 benıgn breast tissue, 50 invasive carcinoma of no special type and 50 invasive lobular carcinoma were randomisely selected from Fırat University Medical Faculty Pathology Department. MAGE–A11 was applied to the samples immunohistochemically. Results: MAGE–A11 expression was observed at 33 of 50 benign breast tissues (66%), 45 of 50 invasive carcinoma of no special type (90%) and 35 of 50 invasive lobular (70%) carcinomas. Conclusion: MAGE–A11 cannot help in distinguishing between benign and malign breast tissues. However, it was concluded that high expression of MAGE–A11 in the no special type of invasive carcinoma can be useful in differential diagnosis with invasive lobular carcinomas.

Özet

Amaç: Meme kanseri akciğer kanserinden sonra en sık görülen ikinci kanser olup kadınlarda görülen kanserlerin %26’sını oluşturmaktadır. Mortalite riski %18’dir. Görüntüleme yöntemleri, sitolojik örneklemeler ve iğne biyopsi örnekleri radikal cerrahiler öncesinde fayda sağlamaktadır. Meme karsinomları farklı histopatolojik özellikler gösterirler. Bunun nedeni tümörün genetik özelliklerinde aranmaya başlanmış olup ve tümörlerde gen ekspresyon paternleri ile ilgili araştırmalar artmıştır. Melanom ilişkili antijen (MAGE) ailesi sitotoksik T lenfosit olarak tanımlanan bir dizi antijenden oluşur. MAGE–A11, malign melanom, meme ve akciğer kanseri gibi tümörlerde salınır. Biz de çalışmamızda benign meme dokusunda ve invaziv karsinom spesifiye edilemeyen tip ile invaziv lobüler karsinomlarda MAGE–A11 salınımını araştırdık. Gereç ve Yöntem: Fırat Üniversitesi Tıp Fakültesi Tıbbi Patoloji Anabilim Dalı arşivinden, 50’şer adet benign meme dokusu, invaziv karsinom spesifiye edilemeyen tip ve invaziv lobüler karsinom olgusu olmak üzere toplam 150 olgu değerlendirmeye alındı. Örneklere immünohistokimyasal olarak MAGE–A11 uygulandı. Bulgular: Çalışmamıza alınan dahil edilen 50 benign meme dokusunun 33’ünde (%66), 50 invaziv karsinom spesifiye edilemeyen tipin 45’inde (%90) ve 50 invaziv lobüler karsinomun 35’inde (%70) pozitif boyanma bulundu. Sonuç: MAGE–A11 salınımı benign meme dokusu ile malign lezyonların ayrımında bir yarar sağlamamaktadır. Ancak invaziv karsinom spesifiye edilemeyen tipte daha fazla salgılanan MAGE–A11’in invaziv lobüler karsinomdan ayrımında yarar sağlayabileceği kanısına varıldı.
