Transrectal ultrasound-guided 10 cores plus fixed-point prostate biopsy for diagnosing prostate cancer / 肿瘤研究与临床

ABSTRACT

Objective To evaluate the clinical value of transrectal ultrasound-guided 10 cores plus fixed-point prostate biopsy for diagnosing prostate cancer.Methods The serum PSA level of 181 patients were determined with ELISA.AU the patients underwent 10 cores plus fixed-point prostate biopsy under the guidance of transrectal ultrasound.Resuits 80 cases with prostate cancer(44.2%),63 cases with benign prostatic hypertrophy (34.8%),36 cases with prostatitis(19.9%),1 cage with tuberculosis(0.6%),and 1 cage with prostate leiomyoma(0.6%).When PSA WaS more than 20 μg/L,the incidence rate of prostate cancer was significantly higher than other PSA levels.Meanwhile,Gleason scores were increased with the advance of PSA levels (P＜0.001).Conclusion Transrectal ultrasound-guided systematic 10 cores plus fixed-point prostate biopsy could significantly enhance the prostate cancer detection rate, and it was important in diagnosing prostate cancer for patients,especially when PsA was more than 20 μg/L.
