Abstract

Objective: The evaluation of relation between PSA values and Gleason Score and clinical phase in prostate adenocarcinoma. Methods: In this study, 68 prostate adenocarcinoma (PACa) and 55 benign prostatic hyperplasia (BPH) cases were examined. Gleason Score (GS) was used as histological grading. They were graded according to WHO and TNM classifiying. The total and free PSA values of the cases were measured. Results: While the mean serum total-PSA (t-PSA) value was 67.091±5.32 ng/ml in cases with PACa, it was 4.701±1.02 ng/ml in cases with BPH. 11 PACa, 24 BPH existed in Grey Zone. There was no difference between t-PSA, free-PSA (f-PSA) and ages, but s-PSA and f-PSA rate was significantly different. The specificity was 92% and sensivity 82% for 0.18 limit value. 8 of 9 PACa cases in t-PSA 0-10 ng/ml were in localised phase and one in metastatic phase. While the GS of these 7 cases were lower than 7, the GS of two cases were at 7-10 interval. We determined the mean serum t-PSA level as 44.8±6.76 ng/ml in the localised phase and 120.2±8.65 ng/ml in metastatic phase. Conclusion: The use of Serum t-PSA level parameter is a helpful determinant. It is a fine determinant in diagnosing and grading prostate carcinoma (PCa), guessing histological grades, following and determining reccurence. It is a helpful parameter to distinguish benign and malign cases whose f-PSA/t-PSA rate and t-PSA value are at 4,1-10 ng/ml level (Grey zone). The use of GS is a good and reliable determinant in establishing the progress and surviving of the cases with PCa.

Özet

Amaç: Prostat adenokarsinomlarında PSA değerlerinin, Gleason skor ve klinik evre ile ilişkisini değerlendirmek. Yöntem: Çalışmamızda 68 prostat adenokarsinomu (PACa) olgusu ile 55 benign protat hiperplazisi (BPH) olgusu incelendi. Histolojik grade olarak Gleason skor (GS) kullanıldı. Olgular WHO ve TNM sınıflamasına göre evrelendirildi. Olguların total (t) ve serbest-PSA (s-PSA) değerleri ölçüldü. Bulgular: Ortalama serum t-PSA değerleri: PACa olguları 67.09±5.32 ng/ml iken BPH’da 4.70±1.02 ng/ml olarak bulundu. Gri Zon aralığında 11 PACa ile 24 BPH olgusu bulunmaktadır. Bu olgularda t-PSA, s-PSA ve yaş arasında bir fark tespit edilemeyip, s-PSA/t-PSA oranı anlamlı derecede farklı bulunmuştur. 0.18 sınır değeri için spesifite % 92, sensitivite % 82’dir. Gri zon aralığında olan 9 PACa olgusunun 8 tanesi lokalize evrede, 1 tanesi metastatik evrede tespit edilmiştir. Bu PSA aralığında 7 olgunun GS’si 7’den düşük iken sadece 2 olgunun GS’si 7-10 aralığında tespit edildi. Lokalize evrede olgularında ortalama serum t-PSA seviyesi: 44.8±6.76 ng/ml iken metastatik evrede 120.2±8.65 ng/ml olarak tespit edildi. Sonuç: Serum t-PSA düzeyi parametresinin kullanımı faydalı bir belirteçtir. PSA; Prostat karsinomu (PCa) tanısında, evrelemesinde, histolojik grade’i tahmin etmede, izlemde ve rekürrenslerin belirlenmesinde iyi bir göstergedir. s-PSA/t-PSA oranı, t-PSA değeri 4,1-10 ng/ml düzeyinde olan (Gri zon) benign ve malign olguları ayırmada son derece yararlı bir parametredir. GS’nin kullanılması, PCa’lı olgularda progresyonu ve sağ kalımı belirlemede iyi ve güvenilir bir göstergedir.
