Abstract

In this study proliferation activities of normal prostate tissue, benign prostate hyperplasia (BPH), prostatic intraepithelial neoplasia (PIN) and prostate cancer samples were evaluated immunohistochemically by using the monoclonal anti-Ki-67 antibody. Ki-67 is a nuclear non-histone protein expressed throughout the cell cycle. The proliferation rate was found to be 0.3-0.8 % in normal prostate glandular epithelium, 0.5-2.2 % in BPH, 1.6-3.7 % in high grade PIN and 5-30 % in prostate cancer cases. BPH showed a slightly higher, whereas PIN and prostate cancer showed significantly higher proliferation activity compared to normal prostate tissue. The Ki-67 proliferation index was found to correlate well with the Gleason classification in the cancer group. It is concluded that the Ki-67 proliferation index can be used a valuable diagnostic marker in PIN and tumor tissue.
Bu çalışmada, normal prostat dokusu, benign prostat hiperplazisi (BPH), prostatik intraepitelyal neoplazi (PIN) ve prostat kanseri doku örneklerinde proliferasyon aktivitesi immünohistokimyasal yöntemle Ki-67 monoklonal antikoru kullanılarak değerlendirildi. Ki-67, hücre siklusu boyunca eksprese edilen nükleer bir non-histon proteindir. Proliferasyon oran›, normal prostat glanduler epitelinde % 0.3-0.8 olarak, BPH de % 0.5-2.2, yüksek evreli PIN de % 1.6-3.7 ve prostat kanser vakalarında % 5-30 olarak bulundu. Proliferasyon aktiviteleri normal prostat dokusu ile karşılaştırıldığında BPH de hafif artış, PIN ve prostat kanserinde anlamlı yüksek artış gösterdi. Ki-67 proliferasyonndeksinin kanser grubunda Gleason sınıflandırmasıyla ilişkili olduğu bulundu. Ki-67 proliferasyon indeksinin de¤erli bir tanı markırı olarak PIN ve tümöral dokularda kullanılabileceği sonucuna varıldı.
