Purpose: The survey was conducted on Korean men to examine information acquisition channel for prostate cancer high risk group as part of the “Blue Ribbon Campaign” of the Korean Urological Oncology Society.Materials and Methods: An online survey of 500 men aged 50 years old or older was completed to query investigation of the status of prostate cancer awareness and information acquisition from February 4 to February 9, 2021.Results: Most men in their 50s and older are well aware that prostate cancer can also occur in young men in their 40s, so the rate of misunderstanding of the timing of prostate cancer screening after their 60s is very low. Two-thirds of all respondents (67.2%) were also confirmed that prostate cancer had no initial symptoms and was not included in the national cancer screening. Seventy-five percent of people look up information on their own in case of suspected prostate cancer, and 51.6% seek out knowledge on their own to prevent prostate cancer. Of the respondents, 27.4% of men contacted prostate cancer-related information within the past year, and the percentage of people contacted through ‘Internet/Phone,’ ‘People Around’ and ‘Television’ was high. The most trusted channel among prostate cancer information channels was ‘medical professionals,’ but the experience rate was not high, and the channel with high experience rate and reliability was shown as ‘television.’Conclusions: Much effort is still needed to understand the information acquisition behavior of Korean men and to improve awareness of early screening for prostate cancer.

Purpose Thirty percent of patients treated with curative intent for localized prostate cancer (PC) experience biochemical recurrence (BCR) with rising serum prostate-specific antigen (sPSA), and of these, approximately 50% succumb to progressive disease. More discriminatory staging procedures are needed to identify occult micrometastases that spawn BCR. Patients and Methods PSA mRNA copies in pathologically normal pelvic lymph nodes (N0-PLN) from 341 localized PC patients were quantified by real-time reverse-transcriptase polymerase chain reaction. Based on comparisons with normal lymph nodes and PLN with metastases and on normalization to 5 × 106 glyceraldehyde-3′-phosphate dehydrogenase mRNA copies, normalized PSA copies (PSA-N) and a threshold of PSA-N 100 or more were selected for continuous and categorical multivariate analyses of biochemical failure-free survival (BFFS) compared with established risk factors. Results At median follow-up of 4 years, the BFFS of patients with PSA-N 100 or more versus PSA-N less than 100 was 55% and 77% (P = .0002), respectively. The effect was greatest for sPSA greater than 20 ng/mL, 25% versus 60% (P = .014), Gleason score 8 or higher, 21% versus 66% (P = .0002), stage T3c, 18% versus 64% (P = .001), and high-risk group (50% v 72%; P = .05). By continuous analysis PSA-N was an independent prognostic marker for BCR (P = .049) with a hazard ratio of 1.25 (95% CI, 1.001 to 1.57). By categorical analysis, PSA-N 100 or more was an independent variable (P = .021) with a relative risk of 1.98 (95% CI, 1.11 to 3.55) for BCR compared with PSA-N less than 100. Conclusion PSA-N 100 or more is a new, independent molecular staging criterion for localized PC that identifies high-risk group patients with clinically relevant occult micrometastases in N0-PLN, who may benefit from additional therapy to prevent BCR.

175 Background: The efficient delivery of adjuvant and salvage therapy after radical prostatectomy in patients with prostate cancer is hampered by a lack of biomarkers to assess the risk of clinically significant recurrence and progression. Methods: Mayo Clinic Radical Prostatectomy Registry (RP) patient specimens were selected from a case-control cohort with 14 years median follow-up for training and initial validation of an expression biomarker genomic classifier (GC). An independent, blinded case-cohort study of high-risk RP subjects was used to validate GC, comparing the performance of GC to a multivariate logistic regression clinical model (CM) and GC combined with clinical variables (genomic-clinical classifier, GCC) for predicting clinical recurrence (defined as positive bone or CT scan within 5 years after biochemical recurrence). The concordance index (c-index) and Cox model were used to evaluate discrimination and estimate the risk of clinical recurrence. Results: In the training subset (n=359), both GC and GCC had a c-index of 0.90 whereas CM had a c-index of 0.76. In the internal validation set (n=186), GC and GCC had a c-index of 0.76 and 0.75, while CM had a c-index of 0.69. In an independent high-risk study (n=219), GC and GCC had a c-index of 0.77 and 0.76, while CM had a c-index of 0.68. In subset analysis of Gleason score 7 patients within the high-risk group, GC and GCC showed improved discrimination with c-index of 0.78 and 0.76, respectively compared to 0.70 for CM. In the high-risk group, the risk of recurrence by GC model score quartiles at 5 years after RP was estimated at 1%, 5%, 5% and 18%. Conclusions: The GC model shows improved performance over CM in the prediction of clinical recurrence in a high-risk cohort and in subset analysis of Gleason score 7 patients. The addition of clinical variables to the GC model did not significantly contribute to classifier performance in patients with high-risk features. We are further testing the performance of the GC and GCC models and their usefulness in guiding decision-making (e.g., for the adjuvant therapy setting) in additional studies of prostate cancer clinical risk groups.

181 Background: Studies on 15-year Post-RP survival including data on PSA relapse (PSA-Rel) are rare. We established the 15-year post-RP prostate cancer specific mortality (PCSM), to explore the time to PSA-Rel and PCSM thereafter, and to identify clinically available prognostic factors. Methods: In men prostatectomized from 1987-2004 slightly modified D`Amico risk groups were identified (T1: No palpable tumor ;”T2 unilateral”/”T2 bilateral” according to tumor palpability in one or both lobes). PSA –Rel was defined as PSA ≥4 µg/l before 2000, and thereafter as PSA >0.2 µg/l. Delay of RP was defined as RP performance 3-12 months after diagnosis. Competing risk modeling was performed with a significance level of <0.05. Results: After a median observation time of 12 years (range: 0-22), of 309 men (median age:62 years [range:40-74]) 40 have died from prostate cancer ( PCa) and 68 due to other causes (15-year PCSM: 15% [95%CI: 10-19%). No difference of PCSM was found between the low (N: 12) and the intermediate group (N: 121), the “conventional” high risk group ( N: 121) displaying a 24% PCSM rate (95% CI:16-32%) with particularly poor prognosis for men who presented with two high risk factors ( N. 32 ; PCSM: 33% [95% CI:20-46%]). The median time to PSA relapse (N: 152) was 5 years (range: 0-17), the median overall survival time after PSA- Rel being 7 years (range: 0-17). PCSM continued to increase after 10 years. Delay of RP had no impact on PCSM. Conclusions: After a median observation time of 12 years approximately 1 of 7 men with localized PCa, most of them diagnosed before the PSA- era, have died of prostate cancer. The “conventional” high-risk group is prognostically heterogeneous: Men with two high risk criteria have a particularly poor prognosis. PSA-Rel 10 years after RP is no rare event followed by survival times of >10 years. Delay of RP for up to one year had no impact on PCSM.
