Abstract

Background/aims: Friend leukemia virus integration-1 expression has been shown in a variety of tumors, including vascular tumors, desmoplastic small round cell tumor, Merkel cell carcinoma, and lymphoblastic lymphoma, in addition to Ewing’s sarcoma/ primitive neuroectodermal tumor. The aim of the current study was to examine Friend leukemia virus integration-1 protein expression in a series of gastrointestinal stromal tumors and also to assess if Friend leukemia virus integration-1 has any role in the disease process. It is the first study analyzing Friend leukemia virus integration-1 expression in gastrointestinal stromal tumors in the English literature. Methods: A tissue microarray block containing 52 cases of gastrointestinal stromal tumors was done. Immunohistochemical analysis was performed for Friend leukemia virus integration-1 polyclonal antibody. Results: Immunohistochemically, Friend leukemia virus integration-1 was negative in all cases. Conclusions: Friend leukemia virus integration-1 can be expressed in a variety of tumors, and is helpful in making the diagnosis of Ewing’s sarcoma/primitive neuroectodermal tumor. We think that this protein is not expressed in gastrointestinal stromal tumors and it is not a part of the pathogenesis of this disease.

Özet

Amaç: Friend leukemia virüs integration-1 ekspresyonunun, "Ewing" sarkoma/primitif nöroektodermal tümör yanında vasküler tümörler, desmoplastik küçük yuvarlak hücreli tümör, Merkel hücreli karsinoma ve lenfoblastik lenfoma gibi çeşitli tümörlerde bulunduğu gösterilmiştir. Bu çalışmanın amacı, gastrointestinal stromal tümörlerde Friend leukemia virüs integration- 1 protein ekspresyonunu ve bu tümörlerin gelişimindeki rolünü araştırmaktır. Bu çalışma, gastrointestinal stromal tümörlerde Friend leukemia virüs integration-1 ekspresyonunu araştıran İngilizce literatürdeki ilk çalışmadır. Yöntem: 52 vaka içeren doku mikroarrey bloğu hazırlanmıştır. Friend leukemia virüs integration-1 poliklonal antikoru kullanılarak kesitler üzerinde immunohistokimyasal inceleme yapılmıştır. Bulgular: İmmunohistokimyasal olarak Friend leukemia virüs integration-1 tüm vakalarda negative bulunmuştur. Sonuç: Friend leukemia virüs integration-1 çeşitli tümörlerde eksprese olabilir ve "Ewing" sarkoma/primitif nöroektodermal tümör tanısı için yardımcıdır. Bulgularımıza dayanarak, bu proteinin gastrointestinal stromal tümörlerde eksprese olmadığını ve bu hastalığın patogenezinde yer almadığını düşünüyoruz.
