Aim: The most common type of cancer in women is breast carcinoma. There is an improvement in prognosis with the developments in early diagnosis possibilities parallel to the developments seen in laboratory methods. One of the important factors in determining the prognosis and response to treatment is the Human Epidermal Growth Factor Receptor 2 (HER2, c-erbB2) gene located on the long arm of Chromosome 17. One of the most frequently used methods in the evaluation of HER-2 gene in breast carcinoma in many medical pathology laboratories is immunohistochemical (IHC) methods. In the IHC method, scoring is made according to the staining percentage of invasive carcinoma cells and the quality of staining (weak-medium-strong / incomplete-complete membranous). In this study, we aimed to reveal the possible differences and their reasons by comparing the IHC evaluation scores of both centers.
Methods: Fifty patients who were diagnosed with breast carcinoma in the last 5 years in our Medical Pathology laboratory, IHC studies were conducted, IHC studies were repeated in Erzurum Atatürk University Medical Pathology Laboratory for various reasons, and both tru-cut biopsy and excisional biopsies were evaluated in both centers. Pathology reports of 50 cases were analyzed retrospectively.
Results: When the evaluations made in both centers were compared, 30 (60%) of tru-cut biopsy materials and 31 (62%) of excisional biopsy materials had the same score.
Conclusion: Although there are similarities between the two centers in the evaluation results, substantial differences were also detected.
Amaç: Kadınlarda en sık görülen kanser tipi meme karsinomudur. Laboratuvar yöntemlerinde görülen gelişmelere paralel erken tanı olanaklarındaki gelişmelerle prognozda iyileşme söz konusudur. Prognozun ve tedaviye cevabın belirlenmesinde önemli faktörlerden birisi de Kromozom 17’nin uzun kolunda yer alan Human Epidermal Büyüme Faktör Reseptör 2 (HER2, c-erbB2) genidir. Meme karsinomunda, HER-2 gen değerlendirilmesinde, birçok tıbbi patoloji laboratuvarında en sık kullanılan yöntemlerden biri immünohistokimyasal (İHK) işlemlerdir. İHK yöntemde, invaziv karsinom hücrelerinin boyanma yüzdesi ve boyanma niteliğine (zayıf-orta-kuvvetli/inkomplet-komplet membranöz) göre skorlanma yapılır. Çalışmamızda, her iki merkeze ait İHK değerlendirme skorlarını kıyaslayarak olası farklılıkları ve nedenlerini ortaya koymayı amaçladık.
Yöntem: Çalışmamıza Tıbbi Patoloji laboratuvarımızda son 5 yılda meme karsinomu tanısı almış, İHK çalışmaları yapılmış, çeşitli nedenler ile Erzurum Atatürk Üniversitesi Tıbbi Patoloji Laboratuvarında yeniden İHK çalışmaları tekrar edilmiş, hem tru-cut biyopsi hem de eksizyonel biyopsileri her iki merkezde değerlendirilmiş 50 hasta dahil edildi. 50 olguya ait Patoloji raporları retrospektif olarak analiz edildi.
Bulgular: Her iki merkezde yapılan değerlendirme kıyaslandığında tru-cut biyopsi materyallerinin 30’u (%60’ı), eksizyonel biyopsi materyallerinin ise 31’i (%62’si) aynı skora sahipti.
Sonuç: Değerlendirme sonuçlarında iki merkez arasında benzerlikler olmasına rağmen, azımsanamayacak kadar farklılıklar da tespit edilmiştir.
