ABSTRACT
Objective To estimate the diagnostic significance and indication of repeated prostate biopsy in patients with persistently abnormal serum PSA.Methods From Jan 2004 to Sep 2011,90 patients with persistently abnormal serum PSA levels underwent transperineal ultrasound guided template prostate biopsy.They were diagnosed as benign lesions (BPH 66/90,PIN 10/90,ASAP 14/90)by previous first biopsies.The ages were 43 to 86 years old (mean age 71),and their PSA levels were fluctuated in a range of 3.1 to 168.0 μg/L (mean 17.6 μg/L),26 patients were abnormal in digital rectal examination (DRE).Results According to the repeated biopsies,it was divided into three groups including benign group (57/90),PIN or ASAP group (5/90) and PCa group (28/90).21.2% patients were confirmed as PCa (14/66) in BPH group,while 60% (6/10) patients in PIN group and 57.1% (8/14) patients in ASAP group were confirmed as PCa.There were significant differences in BPH group compared with PIN or ASAP group (P<0.05).The mean prostate volume (PV) was (65.9±22.6) ml in benign group and (50.4±20.8) mlin PCa group,while abnormal DRE were foundin 7/41 in benign group and 5/9 in PCa group.There was significant differences in PV and DRE between the two groups (P<0.05).There were no significant differences in age,PSA,PSAD,PV or DRE between PIN and ASAP group (P>0.05).Conclusions Repeated biopsy can improve the diagnosis of PCa in patients with persistently abnormal serum PSA.Smaller PV or abnormal DRE in the patients who were diagnosed as BPH by previous first biopsies may strongly need repeated biopsies,while in the patients who were diagnosed as PIN/ASAP by previous first biopsies,repeated biopsies were required despite any age,PSA,PSAD,PV or DRE.
