Studies about the survival of patients with prostate cancer by stage or risk of progression are scarce. The aims of this study were (1) to determine the cause-specific survival by risk in prostate cancer patients in Mallorca diagnosed in the period 2006–2011; (2) to identify the factors that explain and predict the likelihood of survival and the risk of dying from this type of cancer; and (3) to determine the distribution of prostate cancer by risk in the patients in Mallorca diagnosed in the period 2006–2011. Incident prostate cancer cases diagnosed between 2006 and 2011 were identified through the Mallorca Cancer Registry. We collected age; date and method of diagnosis; date of follow-up or death; T, N, M and stage according to the TNM 7th edition; Gleason score; prostate-specific antigen (PSA); histology according to the International Classification of Diseases for Oncology (ICD-O) 3rd edition, comorbidities and treatments. We calculated risk in four categories: low, medium, high and very high. The end point of follow-up was 31 December 2014. Multiple imputation (MI) was performed to estimate cases with unknown risk. We identified 2921 cases. Five years after diagnosis, survival after MI was 89% globally, and was 100% for low-risk cases, 96% for medium risk, 93% for high risk and 69% for very-high-risk cases. Cases with histology other than adenocarcinoma, with high (and especially very high) risk, as well as with systemic, mixed and observation/unspecified treatments had worse prognoses.

Abstract Objectives: 1) to find out the distribution of prostate cancer by risk of progression; 2) to determine the cause-specific survival by risk of progression in prostate cancer; 3) to identify the factors associated with the risk of dying from this cancer.Methods: Incident prostate cancer cases diagnosed between 2006 and 2011 were identified through the Mallorca Cancer Registry. Inclusion criteria: invasive cases with code C61.9 and any histology. Cases identified exclusively through death certificate were excluded. We collected: age; date and method of diagnosis; date of follow-up or death; T, N, M and stage according to the TNM 7th edition; Gleason score; PSA; histology according to the ICD-O 3rd edition 6 ; comorbidities and treatments. We calculated risk in 4 categories: low, medium, high and very high. End point of follow-up was 31 December 2014. Multiple imputation (MI) was performed to estimate cases with unknown risk of progression. Survival analysis was performed using the actuarial and Kaplan-Meier methods, as well as the Cox regression model.Results: We identified 2921 cases. After MI, 9.5% had low risk, 24.9% medium risk, 42.7% high risk and 22.9% very high risk. Five years after diagnosis, survival after MI was 89% globally, that being 100% for low risk cases, 96% for medium risk, 93% for high risk and 69% for very high risk. Cases with histology other than adenocarcinoma, with high and, especially, very high risk of progression, as well as with systemic, mixed and observation/unspecified treatments have worse prognosis. Treatment showed a strong relationship with age and life expectancy.Conclusions: Risk of progression and treatment were the main variables associated to survival in prostate cancer.

Tolsotogo St., Saint Petersburg 197022, RussiaBackground. Prostate cancer (PCa) of a high and very high risk is a potentially fatal disease that requires an active multimodal approach, including the use of neoadjuvant drug treatment. As option for this treatment is neoadjuvant chemohormonal therapy (NCHT) followed by radical prostatectomy (RPE). However, data on the oncological results of treatment of such patients are still limited and the role of neoadjuvant therapy in the treatment of high and very high-risk PCa remains not fully understood.Objective: to assess the oncological results of treatment patients with localized and locally advanced PCa of high and very high risk after NCHT. Materials and methods. This was a prospective randomized study: patients with PCa of high and very high-risk groups (prostate specific antigen levels (PSA) >20 ng/ml and/or Gleason score ³8 and/or clinical stage >T2c) were treated with RPE only (group RPE; n = 35) or NCHT followed by RPE (NCHT/RPE group; n = 36). The neoadjuvant course included the intravenous administration of docetaxel once every 21 days (75 mg/m2 up to 6 cycles) and the antagonist of the gonadotropin releasing hormone degarelix according to the standard scheme (6 subcutaneous injections every 28 days). After a follow-up examination evaluating the result of the neoadjuvant regimen, patients underwent RPE with extanded lymphadenectomy.Results. A mean follow-up was 37.08 ± 20.46 months. A statistically significant reduction of prostate specific antigen >50 % post-chemohormonal therapy was observed in all 36 cases. Lower postoperative stage was noticed in 38.5 % in NCHT/RPE group compared with 2.7 % in RPE group. Similarly, positive surgical margin rate was higher in group without neoadjuvant therapy – 40 and 25 % (RPE group). Cancerspecific survival was 97.2 % in NCHT/RPE group and 87.56 % in the RP group (p = 0.037), cancer specific survival rate – 91.4 % and 97.2 % respectively (log-rank test p = 0.22). At the same time, no statistically significant differences were obtained in 3-year recurrence free survival between groups: 38.8 % in NCHT/RPE group versus 43.6 % in the RPE group (log-rank test p = 0.36).Conclusion. Conducting NCHT before RPE is a safe and effective strategy in patients with PCa of high and very high risk groups and could improve oncological results.

Abstract Objective To evaluate the efficacy and toxicity of SBRT for localized prostate cancer (PCa). Moreover, it is the largest-to-date pilot study to report 5-year outcomes of SBRT for localized PCa from China. Methods In this retrospective study, 133 PCa patients in our center were treated by SBRT with CyberKnife (Accuray) from October 2012 to July 2019. Follow-up was performed every 3 months for evaluations of efficacy and toxicity. Biochemical progression-free survival (bPFS) and toxicities were assessed using the Phoenix definition and the Common Terminology Criteria for Adverse Events (CTCAE) v.5.0 respectively. Factors predictive of bPFS were identified with COX regression analysis. Results 133 patients (10 low-, 21 favorable intermediate-, 31 unfavorable intermediate-, 45 high-, and 26 very high risk cases on the basis of the NCCN risk classification) with a median age of 76 years (range: 54–87 years) received SBRT. The median dose was 36.25Gy (range: 34-37.5Gy) in 5 fractions. Median follow-up time was 57.7 months (3.5–97.2 months). The overall 5-year bPFS rate was 83.6% for all patients. The 5-year bPFS rate of patients with low-, favorable intermediate-, unfavorable intermediate-, high-, and very high risk PCa was 87.5%, 95.2%, 90.5%, 86.3%, and 61.6% respectively. Urinary symptoms were all alleviated after SBRT. All the patients tolerated SBRT with only 1 (0.8%) and 1 (0.8%) patient reporting grade-3 acute and late genitourinary (GU) toxicity, respectively. There were no grade 4 toxicities. Gleason score (P < 0.001, HR = 7.483, 95%CI: 2.686–20.846) was the independent predictor of bPFS rate after multivariate analysis Conclusion SBRT is an efficient and safe treatment modality for localized PCa with high 5-year bPFS rates and acceptable toxicities.

103 Background: Beginning in 2014, the National Comprehensive Cancer Network (NCCN) recognized very high-risk (VHR) prostate cancer (cT3b-T4, or primary Gleason pattern 5, or more than 4 biopsy cores with Gleason score 8-10, or multiple HR features) as a classification distinct from high-risk (HR) disease. Using prospectively collected institutional data, we describe contemporary treatment patterns and short-term outcomes in the VHR population. Methods: Men who underwent radical prostatectomy (RP) between January 2010 and June 2015 were identified using the Johns Hopkins RP database, and trends in management were compared across the study period. Pathological and short-term clinical outcomes were assessed in men with VHR cancer. Non organ-confined disease (NOCD) was defined as ≥ pT3 disease or lymph node positivity, persistent postoperative PSA as ≥ 0.2 ng/mL, and biochemical recurrence (BCR) as a PSA ≥ 0.2 ng/mL following an initial undetectable postoperative PSA. Results: During the study period, 4,954 men underwent RP, of which 161 (3.2%) men had VHR cancer at diagnosis. The annual proportion of men who underwent RP with VHR cancer increased over the study period (chronologically 1.8%, 1.0%, 3.3%, 4.1%, 5.6%, and 5.2%; p<0.001). Sixteen percent of men with VHR disease were enrolled in pre-surgical clinical trials, with an increase from 0% of men in 2010 to 19.1% in 2015 (p=0.11). At RP, 39% of the VHR cohort had seminal vesicle invasion, 26% had lymph node involvement, and a total of 74% had NOCD. Following surgery, 33% of men had PSA persistence, and 40% experienced either PSA persistence or BCR during follow-up (median 13.4 months). Of 136 men with at least one follow-up assessment, 15 (11.0%) developed metastasis; 33% of the cohort was treated with radiation therapy, 42% with androgen deprivation, and 15% with docetaxel. Conclusions: The VHR population carries the greatest risk of clinical progression following local treatment. Over the past five years, we have observed increasing surgical treatment and clinical trial enrollment at our institution. Continued assessment of post-operative interventions and outcomes will help to facilitate counseling and establish point estimates from which to power clinical trials.

PURPOSE This study examined changes in prostate disease screening (prostatic-specific antigen [PSA] testing), prostate biopsy testing, and prostate cancer diagnoses during the COVID-19 pandemic through December 2020. MATERIALS AND METHODS This analysis included test results from men ≥ 40 years, without prior International Classification of Diseases-10 record of prostate cancer since January 2016, who received PSA or prostate biopsy testing at Quest Diagnostics during January 2018-December 2020. Monthly trends were evaluated for three periods: prepandemic (January 2018-February 2020), early-pandemic (March-May 2020), and late-pandemic (June-December 2020). RESULTS Meeting inclusion criteria were 16,365,833 PSA and 48,819 prostate biopsy results. The average monthly number of PSA tests declined from 465,187 prepandemic to 295,786 early-pandemic (36.4% decrease; P = .01) before rebounding to 483,374 (3.9% increase; P = .23) late-pandemic. The monthly average number of PSA results ≥ 50 ng/mL (23,356; 0.14% of all PSA results) dipped from 659 prepandemic to 506 early-pandemic (23.2% decrease; P = .02) and rebounded to 674 late-pandemic (2.3% increase; P = .65). The average monthly number of prostate biopsy results decreased from 1,453 prepandemic to 903 early-pandemic (37.9% decrease; P = .01) before rebounding to 1,190 late-pandemic (18.1% decrease; P = .01). The average monthly number for Gleason score ≥ 8 (6,241; 12.8% of all prostate biopsies) declined from 182 prepandemic to 130 early-pandemic (28.6% decrease; P = .02) and decreased to 161 late-pandemic (11.5% decrease; P = .02). CONCLUSION The findings suggest that a substantial number of prostate screening opportunities and cancer diagnoses have been missed. Efforts are needed to bring such patients back for screening and diagnostic testing and to restore appropriate care for non–COVID-19–related medical conditions.

Abstract Objective To evaluate the efficacy and safety of SBRT for localized prostate cancer (PCa) with CyberKnife in China. Moreover, it is the largest-to-date pilot study to report 5-year outcomes of SBRT for localized PCa from China. Methods In this retrospective study, 133 PCa patients in our center were treated by SBRT with CyberKnife (Accuray Inc., Sunnyvale, USA) from October 2012 to July 2019. Follow-up was performed every 3 months for efficacy and toxicity evaluation. Biochemical progression-free survival (bPFS) and toxicities were assessed using the Phoenix definition and the Common Terminology Criteria for Adverse Events (CTCAE) v.5.0, respectively. Factors predictive of bPFS were identified with COX regression analysis. Results 133 patients (10 low-, 21 favorable intermediate-, 31 unfavorable intermediate-, 45 high-, and 26 very high risk cases on the basis of NCCN risk classification) with a median age of 76 years (range 54–87 years) received SBRT. The median dose was 36.25 Gy (range 34–37.5 Gy) in 5 fractions. Median follow-up time was 57.7 months (3.5–97.2 months). The overall 5-year bPFS rate was 83.6% for all patients. The 5-year bPFS rate of patients with low-, favorable intermediate-, unfavorable intermediate-, high-, and very high risk PCa was 87.5%, 95.2%, 90.5%, 86.3%, and 61.6%, respectively. Urinary symptoms were all alleviated after SBRT. All patients tolerated SBRT with 1 (0.8%) patient reporting grade-3 acute and 1 (0.8%) patient reporting grade-3 late genitourinary (GU) toxicity, respectively. There were no grade 4 toxicities. Gleason score (P < 0.001, HR = 7.483, 95%CI: 2.686–20.846) was the independent predictor of bPFS rate after multivariate analysis. Conclusion SBRT is an efficient and safe treatment modality for localized PCa with high 5-year bPFS rates and acceptable toxicities.

59 Background: The consequences of a low prostate-specific antigen (PSA) in high-grade (Gleason 8-10) prostate cancer are unknown. We sought to evaluate the clinical implications and genomic features of this entity. Methods: Clinical and transcriptomic data from 626,057 patients with N0M0 prostate cancer were collected from two national cohorts and a large transcriptome database. Multivariable Fine-Gray and Cox regressions analyzed prostate-cancer specific mortality (PCSM) and all-cause mortality, respectively. GRID data were used to analyze transcriptomic features. Results: For Gleason 8-10 disease, the distribution of PCSM was U-shaped by PSA (PSA 4.1-10.0 ng/mL = referent), with adjusted hazard ratio (AHR) 2.70 for PSA ≤2.5 ng/mL (P < 0.001) versus 1.97, 1.36, and 2.56 for PSA 2.6-4.0, 10.1-20.0, and > 20.0 ng/mL, respectively. In contrast, distribution of PCSM by PSA was linear for Gleason ≤7 with AHR 0.41 for PSA ≤2.5 ng/mL (P = 0.127) versus 1.38, 2.28, and 4.61 for PSA 2.6-4.0, 10.1-20.0, and > 20.0 ng/mL, respectively (PGleason*PSA interaction< 0.001). Gleason 8-10, PSA ≤2.5 ng/mL disease had a significantly higher PCSM than standard high and very high-risk disease with PSA > 2.5 ng/mL (AHR 2.15, P = 0.009; 47-month PCSM 13.8% versus 4.9%). Among Gleason 8-10 patients treated with definitive radiotherapy, androgen deprivation therapy (ADT) was associated with a survival benefit for PSA > 2.5 ng/mL (AHR 0.87, P < 0.001) but not for ≤2.5ng/mL (AHR 1.36, P = 0.084; PADT*PSA interaction= 0.021). For Gleason 8-10 tumors, PSA ≤2.5 ng/mL was associated with a higher expression of neuroendocrine markers compared to > 2.5 ng/mL (P = 0.046), with no such relationship for Gleason ≤7. Conclusions: Low-PSA, high-grade prostate cancer appears to be a unique entity that has a very high risk for PCSM, potentially responds poorly to ADT, and is associated with neuroendocrine genomic features.

Background. Only truly long-term follow-up can determine the ultimate outcome in prostate cancer. Most studies have a median follow-up of less than 10 years and then project outcomes out to 15 and 20 years. We sought to follow patients for at least 20 years. Materials and Methods. We followed 754 prostate cancer patients treated with radical prostatectomy from 1988 to 1995 for a median follow-up (in survivors) of 23.9 years. We excluded lymph node and seminal vesicle positive patients and an additional 47 patients that did not have baseline prostate-specific antigen (PSA). This left 581 patients for analysis. Results. With the factors of PSA, Gleason score, and extraprostatic extension/margin positivity, we could partition patients into three risk groups for biochemical failure (low, intermediate, and high). In further analysis, we found that the risk of metastatic disease in the first two groups was almost identical (4% and 5%, respectively), while it was 19% in the high-risk group. High-risk patients were those with PSA >20 ng/ml and/or Gleason >7, or Gleason 7 + PSA 10–20 + epe (and or margin) positive. They had a 22% prostate cancer mortality. Conclusion. In patients with truly long-term follow-up after prostatectomy for prostate cancer, the risk of metastatic disease and cancer death is very low. Patients with the lower risk findings do not appear to benefit from routine follow-up after 10 years free of biochemical recurrence. With a higher risk of later failure, we recommend that the higher risk patients be followed at least intermittently for another 5 years (out to 15 years).

Introduction To determine the prognostic significance of long-term adjuvant androgen deprivation therapy (A-ADT) over 1 year in achieving undetectable levels of prostate-specific antigen (PSA) less than 0.001 ng/mL in prostate cancer patients with high- or very high-risk prostate cancer who underwent radiotherapy (RT). Materials and methods A total of 197 patients with prostate cancer received RT, with a follow-up of ≥12 months. Biochemical failure was defined as PSA ≥nadir + 2 ng/mL after RT. We analyzed clinical outcomes, including survival, failure patterns, and prognostic factors affecting outcomes. Results Biochemical failure-free survival (BCFFS), clinical failure-free survival, distant metastasis-free survival, cancer-specific survival, and overall survival (OS) rates at 5 years were 91.1%, 95.4%, 96.9%, 99.5%, and 89.1%, respectively. Administration of long-term A-ADT significantly predicted favorable BCFFS (p = 0.027) and OS (p < 0.001) in multivariate analysis. Nadir PSA ≤0.001 ng/mL was an independent prognostic factor for BCFFS (p = 0.006) and OS (p = 0.021). The use of long-term A-ADT significantly affected nadir PSA ≤0.001 ng/mL (p < 0.001). The patients with A-ADT for 1 year or longer had better BCFFS or OS than those for less than 1 year or those without A-ADT (p < 0.001). The best prognosis was demonstrated in patients treated with long-term A-ADT and nadir PSA ≤0.001 ng/mL in BCFFS (p < 0.001). Conclusion The addition of long-term A-ADT over 1 year to RT demonstrated good treatment outcomes in patients with locally advanced prostate cancer. Achieving a nadir PSA value ≤0.001 ng/mL using combination therapy with RT and A-ADT is a powerful clinical predictor of treatment outcomes.
