Purpose To assess the predictive ability of prostate-specific antigen (PSA) velocity (PSAV) and doubling time (PSADT) for biopsy progression and adverse pathology at prostatectomy among men with low-risk prostate cancer enrolled on an active-surveillance program. Methods We evaluated 290 men who met criteria for active surveillance (ie, PSA density < 0.15 ng/mL/cm3 and Gleason score ≤ 6 with no pattern ≥ 4, involving ≤ 2 cores with cancer, and ≤ 50% involvement of any core by cancer) with two or more serial PSA measurements after diagnosis from 1994 to 2008. Follow-up included twice-yearly digital rectal exam and PSA measurements and yearly surveillance biopsy. Treatment was recommended for biopsy progression (ie, Gleason score ≥ 7, or > 2 positive cores, or > 50% core involvement). Sensitivity and specificity of postdiagnostic PSAV and PSADT were explored by using receiver operating characteristic (ROC) analysis. Results Overall, 188 (65%) men remained on active surveillance, and 102 (35%) developed biopsy progression at a median follow-up of 2.9 years. PSADT was not significantly associated with subsequent adverse biopsy findings (P = .83), and PSAV was marginally significant (P = .06). No PSAV or PSADT cut point had both high sensitivity and specificity (area under the curve, 0.61 and 0.59, respectively) for biopsy progression. In those who eventually underwent radical prostatectomy, PSAV (P = .79) and PSADT (P = .87) were not associated with the presence of unfavorable surgical pathology. Conclusion Postdiagnostic PSA kinetics do not reliably predict adverse pathology and should not be used to replace annual surveillance biopsy for monitoring men on active surveillance.

The Mean

Purpose: We assessed the outcomes of men with low-risk prostate cancer enrolled in active surveillance. Methods: From January 2008, patients in our clinic who were classified as having low-risk prostate cancer according to the D’Amico classification were included in the protocol. Follow-up consisted of regular prostate-specific antigen tests, digital rectal examinations and biopsies. Outcomes were compared between men who progressed and those who did not, and survival analysis was obtained. Results: The mean follow-up period was 46 months. A total of six patients received curative treatment during follow-up as a result of meeting progression criteria. The mean follow-up time from the beginning of active surveillance until curative therapy was 27.1 months. Four of our 64 patients lost their lives due to diseases other than prostate cancer, none of the patients were lost due to prostate cancer. When patients who showed progression and those who did not were compared in terms of positive core numbers and the core tumour percentage we found no significant difference between the two groups ( P>0.05) Conclusion: Active surveillance seems to be a safe and feasible practice in men with low-risk prostate cancer. Gleason score, clinical stage and initial prostate-specific antigen seem to be the most definite criteria for the selection of patients, while it is thought that the number of positive cores is a matter that can be dealt with more flexibility. Level of evidence: Not applicable for this multicentre audit.

Objective: In this study, we aimed to determine the predictive factor for additional treatment requirement in active surveillance (AS) for patients with low or very low-risk prostate cancer (PCa) and we investigated the effect of tumor burden by total core involvement rate in biopsy to predict of need for additional treatment.Material and methods: 107 patients with PCa in AS between 2005 and 2018 have been evaluated retrospectively. Groups were divided into two groups according to the need for additional treatment. Group 1 received additional treatment, group 2 did not receive additional treatments and active surveillance was continued. Patient’s total prostate-specific antigen (tPSA), prostate-specific antigen density (PSA-D), total core involvement count, quantity and rate at biopsy pathology results and follow-up period were recorded and compared in the two groups. Results: The current cohort includes 107 patients. Mean age at diagnosis was 63.01years. Mean tPSA values at diagnosis were 6.09 ng/mL and 5.2 ng/mL in the group 1 and group 2, respectively. Mean follow-up period was 38.1 months (range, 12 to 134 months). Only PSA-D measurement significantly predicted need for additional treatment (p = 0.017). ROC analysis showed that the optimal threshold was 0.13 ng/mL/cc (sensitivity: 70.8%; specificity: 57.1%). Additional treatment requirement was not detected in patients with PSA-D cut-off level less than 0.07 ng/mL/cc. Conclusions: Total tumor burden of less than 5% is safe for patients with low or very low-risk PCa in AS. A 0.13 ng/mL/cc cut-off level of PSA-D can predict to need for additional treatment in patients managed by AS.
