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.eninfo:eu-repo/semantics/openAccessKi-67ProliferationProstate cancerBenign prostate hyperplasiaProstatic intraepithelial neoplasiaProliferasyonProstat kanseriBenign prostat hiperplazisiProstatik intraepiteliyal neoplaziEvaluation of the Proliferating Activities of Normal and Carcinomatous Prostatic Tissues With Ki-67Article10711124500440
