摘要
AIM: We evaluated the influence of ratio between free-to-total prostate specific antigen (FIT PSA) and prostate specific antigen density (PSAD)-(F/T)/PSAD on reduction of unnecessary prostate biopsies in grey zone (prostate specific antigen (psa) value 4.0-10.0 ng/ml). METHODS: The study included 108 patients. For all patients serum total PSA (T PSA), free PSA (F PSA), FIT PSA and PSAD were analyzed. The group was divided due to the prostate volume into: entire group (regardless the prostate VOL-Group I) and group with prostate VOL<40 (Group 2). RESULTS: Seventy five patients were diagnosed with benign prostatic hyperplasia (BPH) and 33 with prostate cancer (CaP). F/T PSA and (F/T)/PSAD showed significantly lower values in patients with CaP versus those with BPH, while PSAD had significantly higher values. For the cutoff values of 1.12 for (F/T)/PSAD, we found sensitivity to be 67% and specificity 60%, and the (AUC) 0.701. For patients with VOL<40, statistical significance remained with AUC of 0.732 (p=0.003), cutoff was 0.82, and with sensitivity 77% and specificity 68%. CONCLUSIONS: Most significant prostate carcinoma predictors were PSAD and (F/T)/PSAD, where we proposed that patients with (F/T)/PSAD values below 1.49 +/- 0.94 and PSAD values above 0.17 +/- 0.06 should be included for biopsy.
