ABSTRACT
Objective To improve the finding of prostate cancer (PCa) and prevent the unnecessary biopsies, we select proper patients for biopsy and analyze. Methods The retrospective study included 258 patients who were biopsied for suspected early PCa. Then we analyse how the age, prostate volume, PSA, transrectal ultrasound sonography (TRUS) and MRI affect the finding of prostate cancer. Results Altogether 146 BPH and 112 prostate cancer by biopsy were detected. Positive ratio of biopsy was increased with the age or PSA increases but has no relationship with the prostate volume. Combination with digital rectal examination, PSA and TRUS, the positive ratio was improved and unecessary biopsies were avoided. The detective rate reached 84.6% when all of these three parameters were positive. The sensitivity of MRI was 98.3% but specificity was only 22.4%. The total efficacy was 21.8%. Conclusions The effect of DRE, PSA and TRUS in the screening of prostate cancer should be emphasized. However, importance of MRI is limited for the early detection of PCa.
