When prostate volume is between 30-60 cc, 12-core biopsy is essential, but for prostate volume over 60 cc, the difference between 6- and 12-core is insignificant, thus additional core biopsy is necessary.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: To compare 6- or 12-core first biopsy results in the prostate and to determine the relationship between biopsy core number and percentage of cancer detected.

Abstract

Objective: To compare 6- or 12-core first biopsy results in the prostate and to determine the relationship between biopsy core number and percentage of cancer detected. Materials and methods: Prostate biopsy results of the patients in our clinic were investigated retrospectively for the last five years. Patients with prostate specific antigen (PSA) level of 4-10 ng/mL and first line biopsies were included in the study. Standard biopsy procedure was applied as 6- or 12-cores. Age, PSA level, free PSA ratio, digital rectal examination (DRE) results, prostate volume measured by transrectal ultrasonography, percentage of cancer detected, and their distribution according to Gleason scores were investigated. Results: The results of 383 biopsies were evaluated. The mean age was 66 years, prostate volume was 50 cc, PSA level was 6 ng/mL, and free/total PSA ratio was 17%. Although the percentage of cancer detection was higher in 12-core biopsies than 6-core (21.5% vs. 25.3%), this difference was not statistically significant. In multivariate analysis, PSA and DRE findings were identified as factors affecting cancer detection. In patients with prostate volume of 30-60 cc, cancer detection rate was higher in 12-core biopsy group, but similar in other volumes. Conclusion: In patients with PSA level of 4-10 ng/mL, prostate volume is <30 cc, and DRE findings are positive; 6-core first prostate biopsy is sufficient. When prostate volume is between 30-60 cc, 12-core biopsy is essential, but for prostate volume over 60 cc, the difference between 6- and 12-core is insignificant, thus additional core biopsy is necessary.

Özet

Amaç: Prostat 6- veya 12-kor ilk biyopsi sonuçlarının karşılaştırılması ve kor sayısı ile saptanan kanser yüzdesi arasındaki ilişkinin belirlenmesi. Gereç ve yöntem: Kliniğimizde prostat biyopsisi yaptığımız hastaların sonuçları son beş yıl için retrospektif olarak incelendi. Prostat spesifik antijen (PSA) değeri 4 ila 10 ng/mL arasında olanlar ve ilk biyopsisi yapılanlar çalışmaya alındı. Biyopsi işlemi standart olarak 6- veya 12-kor şeklinde yapıldı. Olguların yaş, PSA, serbest PSA oranları, parmakla rektal inceleme (PRİ) sonuçları, transrektal ultrasonografi ile ölçülen prostat hacimleri, tümör saptanma oranları ve bunların Gleason skorlarına göre dağılımı incelendi. Bulgular: Toplam 383 biyopsinin sonuçları incelendi. Ortalama yaş 66, prostat hacmi 50 cc, PSA düzeyi 6 ng/mL ve serbest PSA oranı %17 bulundu. Kor sayısı 12 olan grupta kanser saptama yüzdesi 6-kor grubuna göre daha yüksek (%21.5 ve %25.3) olmasına rağmen fark istatistiksel olarak anlamlı değildi. Çok değişkenli analizde kanser saptanmasını etkileyen faktörler PSA ve PRİ sonucu olarak belirlendi. Prostat hacmi 30-60 cc arasındaki grupta 12-kor biyopsi ile anlamlı derecede daha yüksek oranda kanser tanısı kondu, diğer hacimlerde sonuçlar benzerdi. Sonuç: PSA 4-10 ng/mL, prostat hacmi <30 cc ve PRİ bulgusu olanlarda 6-kor ilk prostat biyopsisi yeterlidir. Prostat hacmi 30-60 cc arasında ise 12-kor biyopsi almak gerekir, ancak hacim 60 cc üzeri olduğunda 6- ve 12-kor arasındaki fark anlamsızdır, ek kor biyopsi gereklidir.
