137 Background: Improved imaging modalities identify metastatic prostate cancer earlier. Atypical and oligometastatic disease is identified more often. Thus a more individual treatment approach in oligometastatic prostate cancer is getting more popular. We demonstrate our results in recurrent disease in seminal vesical remnants after radical prostatectomy and radiotherapy. Methods: A total of 33 patients underwent open resection of locoregional recurrence in seminal vesicals. In case of suspicious 68Ga-PSMA-PET findings in the small pelvis an additional ipsilateral lymph node dissection was performed in 10 patients. 11 patients already received hormone treatment fulfilling the definition of castration resistant prostate cancer. Age, PSA-DT, PSA, time to recurrence after primary treatment resection status were used in a uni and multivariate-cox regression analysis for biochemical relapse after surgery. Results: Median patient age at time of salvage surgery was 70(57-77) years. Median PSA and PSA-DT was 2.79(0.4-61.54)ng/ml and 5.4(1.6-20.1)months respectively. Median surgical time and hospital stay was 132 (75-313)min and 5.5(4-13)days. Median progression-free survival was 29 (8-47) months. After a mean follow-up of 22 months (3-68) months three patients died 8, 14, and 40 months after salvage surgery. In a univariable cox-regression analyses age at time of surgery, preoperative PSA and the time from primary treatment to salvage surgery have been identified as significant parameters for biochemichal relapse. Only the interval from primary to salvage surgery was significant with a Hazard ratio of 1.008 (95%-CI 1.001-1.015, p=0,018) in multivariate analysis. 4 adjunctive surgeries (Ureterovericoneostomy n=3 and one nephrectomy) were needed due to local progressive disease. Conclusions: Seminal vesicle resection is feasible with no significant intra and postoperative complications even in CRPC. Although there is a good median progression-free survival after 5 years almost all patients had biochemical or systemic relapse. Salvage surgery must be seen as prevention for local symptoms, to our experience most often postrenal ipsilateral obstruction.

e15204 Background: Epidemiological studies indicate that the use of calcium channel blockers (CCB) is inversely related to prostate cancer (PCa) incidence. The goal of this study was to examine the association between CCB use and PCa aggressiveness at the time of radical prostatectomy (RP) or outcome after RP. Methods: Information on medication use, PCa aggressiveness and outcome after RP was retrieved from a prospective database that contains clinical and follow-up (FU) data for all men that have undergone RP at the Department of Urology at Roswell Park Cancer Institute since 1992. The database was queried for anti-hypertensive medication use at the time of diagnosis for all patients with ≥ 1 year FU. Prostate cancer aggressiveness (risk status) and recurrence were defined using NCCN guideline definitions. Cox regression models were performed to compare the distribution of progression-free survival (PFS) and overall survival (OS) with adjustment for covariates. Chi-Square test was used to assess the relationship between CCB use and PCa aggressiveness. Results: 875 men were included in the study. At diagnosis, mean age was 60 (SD ± 7) years and mean serum PSA value was 7.4 (SD ±7.4) ng/ml. 48%, 37%, and 15% of patients had low risk, intermediate risk, or high risk PCa, respectively. 104 (12%) had a history of CCB use. CCB users and non-users were similar by PSA at diagnosis (p=0.97) and tumor aggressiveness (p=0.88). Patients taking CCB were more likely to be older (p=0.023), have a higher BMI (p=0.006) and use additional anti-hypertensive medications (p<0.01). Margin status after radical prostatectomy was similar (p=0.30) between the two groups. Median FU was 42 months. PFS (p=0.82, HR 95% CI: 0.63-1.44) and OS (p=0.72, HR 95% CI: 0.42-3.52) did not differ between the 2 groups. Adjusting for age and PCa aggressiveness did not alter the results observed for PFS (p=0.44, HR 95% CI: 0.62–1.41) and OS (p=0.50, HR 95% CI: 0.04-3.48). PCa aggressiveness was associated with PFS (p=0.001) in the multivariate model. Conclusions: CCB use does not affect PCa aggressiveness at time of diagnosis or improve PFS or OS.

Abstract Background Optimal management for recurrent IDH-mutant glioma after radiation therapy (RT) is not well-defined. This study assesses practice patterns for managing recurrent IDH-mutant astrocytoma (Astro) and 1p/19q codeleted oligodendroglioma (Oligo) after RT and surveys their clinical outcomes after different salvage approaches. Methods Ninety-four recurrent Astro or Oligo patients after RT who received salvage systemic therapy (SST) between 2001 and 2019 at a tertiary cancer center were retrospectively analyzed. SST was defined as either alkylating chemotherapy (AC) or non-alkylating therapy (non-AC). Overall survival (OS) and progression-free survival (PFS) were calculated using the Kaplan-Meier method from the start of SST. Multivariable analysis (MVA) was conducted using Cox regression analysis. Results Recurrent Oligo (n=35) had significantly higher PFS (median: 3.1 vs 0.8 years, respectively, P = 0.002) and OS (median: 6.3 vs 1.5 years, respectively, P &lt; 0.001) than Astro (n=59). Overall, 90% of recurrences were local. Eight-three percent received AC as the first-line SST; 50% received salvage surgery before SST; approximately 50% with local failure &gt;2 years after prior RT received reirradiation. On MVA, non-AC was associated with worse OS for both Oligo and Astro; salvage surgery was associated with improved PFS and OS for Astro; early reirradiation was associated with improved PFS for Astro. Conclusions Recurrent radiation-relapsed IDH-mutant gliomas represent a heterogeneous group with variable treatment approaches. Surgery, AC, and reirradiation remain the mainstay of salvage options for retreatment.

Aim. The aim of this study is to present the oncologic outcomes and to determine the prognostic factors of overall survival (OS), cancer-specific survival (CSS), disease-progression-free survival (DPFS), and biochemical-progression-free survival (BPFS) after surgery for pT3 prostate cancer (PCa).Methods. Between 2002 and 2007, a pT3 stage after radical prostatectomy was detected in 182 patients at our institution. The Kaplan-Meier analysis was used to calculate OS, CSS, DPFS, and BPFS. Cox regression was used to identify predictive factors of survival.Results. pT3a was detected in 126 (69%) and pT3b in 56 (31%) of cases. Five-year OS, CSS, DPFS, and BPFS rates were 90.7%, 94%, 91.8%, and 48.4%, respectively. Survival was significantly different when comparing pT3a to pT3b groups. The 5-year OS, CSS, DPFS, and BPFS were 96% versus 72%, 98% versus 77%, 97.3% versus 79.3%, and 60% versus 24.2%, respectively. Specimen Gleason score was the most significant predictor of OS, CSS, DPFS, and BPFS. The risk of death increased up to 3-fold when a Gleason score 8–10 was present at the final pathology.Conclusions. Radical prostatectomy may offer very good CSS, OS, DPFS, and BPFS rates in pT3a PCa. However, outcomes in patients with pT3b or specimen Gleason ≥8 were significantly worse, suggesting the need for multimodality treatment in those cases.

<b><i>Background:</i></b> To demonstrate the feasibility of resecting isolated locally relapsing seminal vesicle remnants after primary radical prostatectomy and radiotherapy. Early oncologic outcomes and prognostic risk factors for relapse are demonstrated. <b><i>Objectives and Methods:</i></b> A total of 32 patients underwent open resection of locoregional prostate cancer recurrence in seminal vesicles, as documented on either MRI, <sup>11</sup>C-choline, or <sup>68</sup>Ga-PSMA PET/CT scans. Age, PSA-DT, PSA, and time to recurrence after primary treatment resection status were used in a uni- and multivariate Cox regression analysis for biochemical relapse after surgery. <b><i>Results:</i></b> Median patient age at time of salvage surgery was 70 (57–77) years. Median PSA and PSA-DT was 2.79 (0.4–61.54) ng/mL and 5.4 (1.6–20.1) months, respectively. Median surgical time and hospital stay was 132 (75–313) min and 5.5 (4–13) days, respectively. After a mean follow-up of 29 (2–92) months, 3 patients died at 8, 14, and 40 months after salvage surgery, and 6 (18.75%) patients remain without biochemical relapse and further treatment. Median progression-free survival was 12 (1–81) months. In the univariable Cox regression analysis, age at time of surgery, preoperative PSA, and the time from primary treatment to salvage surgery were identified as significant parameters for biochemical relapse. Only the interval from primary to salvage surgery was significant in the multivariate analysis with a hazard ratio of 1.008 (95% CI: 1.001–1.015, <i>p</i> = 0.018). In the entire cohort, 4 adjunctive surgeries (3 ureteroneocystostomies and 1 nephrectomy) were needed due to local progressive disease. <b><i>Conclusion:</i></b> Seminal vesicle resection is feasible with no significant intra- or postoperative complications. Almost all patients progressed to biochemical or systemic relapse. Salvage surgery must be seen as a preventive for local symptoms, in our experience most often postrenal ipsilateral obstruction.

444 Background: It is unclear whether prior RS of primary tumor is associated with response and outcomes with ICI in aUC. We hypothesized that such response and outcomes would not differ based on prior RS. Methods: We performed a retrospective cohort study including patients (pts) with aUC who received ICI. We compared overall response rate (ORR), progression-free survival (PFS), and overall survival (OS) between pts with vs without RS [cystectomy or (nephro)-ureterectomy]. Analysis was stratified based on ICI therapy line (first-line vs salvage). A separate comparison between pts with prior RS or radiation (RT) only or none was also pursued. ORR was compared between groups using logistic regression, as well OS and PFS using cox regression analysis; a multivariable model was built adjusting for calculated Bellmunt score. P<0.05 was significant. Results: We identified 984 pts from 24 institutions; 682, 704 and 673 were included in OS, PFS and ORR analyses, respectively; 54% of pts had prior RS with median age 68 at ICI initiation with RS vs 71 without RS with similar proportion of men (73-74%) and ever smokers (70-71%). The RS group had higher proportion (%) of white pts (77% vs 71%), lower % of pts with Hb<10g/dL at ICI initiation (23% vs 32%) but not significantly higher % of liver metastasis at ICI initiation (23% vs 17%). Bellmunt score with vs without RS was 16% vs 11%, 50% vs 48%, 27% vs 37%, 7% vs 4% for 0, 1, 2, and 3, respectively. ORR and PFS were not significantly different between groups, while prior RS was associated with longer OS (unadjusted HR 0.8, p=0.03). However, after adjustment for Bellmunt score, this association was not significant (table). Upon stratification based on treatment line, OS was longer with prior RS (0.7, p=0.03) for those treated with salvage ICI but this was not significant after adjusting for Bellmunt score. ORR, PFS and OS were not significantly different between pts receiving prior RT only vs RS vs none. Conclusions: Prior RS was not significantly associated with longer OS in pts with aUC receiving ICI after adjusting for Bellmunt score. Further work is needed to interrogate tumor-host immune interactions and identify biomarkers that can be prognostic and/or predictive of ICI response. [Table: see text]

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.

Aim: To evaluate the influence of YB-1 rs10493112 variant as a genetic marker for response to second-generation androgen receptor axis-target agents. Methods: A hospital-based cohort study of 78 patients with metastatic castration-resistant prostate cancer was conducted. Genotyping was performed by TaqMan® allelic discrimination technology. Main results: In abiraterone-treated and high-risk patients, YB-1 rs10493112 AA genotype carriers showed lower progression-free survival than C allele genotype patients (4 vs 17 months; p = 0.009). For carriers of AA genotype, multivariate Cox regression analysis revealed a fivefold increased risk of progression (p = 0.035). Conclusion: The study findings suggest that, for metastatic and castration-resistant prostate cancer patients, this polymorphism might be a putative marker for the clinical outcome.
