207 Background: Salvage radiotherapy (S-RT) for patients with prostate cancer who developed PSA failure after radical prostatectomy is widely applied. However, current status of this approach in Japan has not been surveyed so far. The aim of this study was to reveal the present conditions and outcomes of S-RT for Japanese patients with biochemically recurrent prostate cancer. Methods: Clinical data of the S-RT was gathered by sending a questionnaire to participating facilities to the Japanese Radiation Oncology Study Group (JROSG). The S-RT was defined as external-beam radiotherapy delivered to the prostate bed to patients with prostate cancer who eventually developed PSA failure, although their PSA value had once reached <0.2 ng/ml after prostatectomy. In addition, the interval between prostatectomy and the S-RT should essentially be six months or longer. PSA failure-free survival (PFFS) and clinical failure-free survival (CFFS) was calculated by the Kaplan-Meier estimation. Results: 371 cases were registered from 38 facilities. Among them, hormonal therapy was combined with S-RT in 151 patients. In 3 cases, chemotherapy was combined before or after the S-RT. The rests of the cases were treated by S-RT alone. However, prognostic information was insufficient in 28 cases, and PSA nadir was >0.2 ng/ml in 3 cases. Therefore, outcome studies were conducted in the remaining 186 cases. The median age was 67 years old. The nadir value of the PSA after prostatectomy and the PSA value at the initiation of S-RT were 0.0135 ng/ml and 0.292 ng/ml, respectively. The median period between prostatectomy and the S-RT was 18.6 months. Median follow-up period was 58 months. The 5-year PFFS and CFFS were 50.1% (95%CI: 42.8 – 57.9) and 90.1% (95%CI: 86.4 – 95.7), respectively. PFFS was significantly superior in patients with PSA values <= 0.3 ng/ml at the initiation of S-RT than those of PSA values > 0.3. (57.5% vs. 40.5%, p = 0.027) Conclusions: In Japan, hormonal therapy was combined with S-RT in about 40% of the cases. The 5-year PFFS and CFFS rates of cases treated by S-RT alone were 50.1% and 90.1%, respectively. A PSA value of 0.3 was significant cut-off point for predicting PFFS.

(1) Purpose: To investigate the role of 68Ga-PSMA-11 PET/CT in guiding retreatment stereotactic body radiation therapy (SBRT) in prostate cancer (PCa) patients in biochemical recurrence (BCR) after salvage radiotherapy (S-RT). (2) Methods: We retrospectively evaluated PCa patients previously treated with S-RT on the prostate bed and with proven serum prostate antigen (PSA) failure after S-RT. In all patients (pts), 68Ga-PSMA-11 PET/CT was positive in the prostate bed only and guided retreatment SBRT. All retreatments were performed by applying the same radiotherapy protocol (median dose of 18 Gy/3 fractions; IQR 18–21 Gy). The median follow-up was 27 months (range 4–35 months). (3) Results: 38 consecutive patients were considered in this analysis. The overall median PSA level before RT was 1.10 ng/mL (IQR 0.82–2.59). PSA decreased at 3 and 6 months after treatment, with a median value of 0.60 ng/mL (IQR 0.31–0.96; p < 0.001) and 0.51 ng/mL (IQR 0.29–1.17; p < 0.001), respectively. Overall, biochemical recurrence-free survival (b-RFS) was 15.0 months (95% CI 13–23). Grade-1 toxicity was reported in 31.6% of patients (12/38). (4) Conclusion: These results confirm that 68Ga-PSMA-11-PET/CT is able to identify the site of recurrence in patients who have failed S-RT, thus supporting the use of metastases-directed radiotherapy as a safe and effective treatment.

Abstract Background Hypofractionated post-prostatectomy radiotherapy is emerging practice, however with no randomized evidence so far to support it’s use. Additionally, patients with persistent PSA after prostatectomy may have aggressive disease and respond less well on standard salvage treatment. Herein we report outcomes for conventionally fractionated (CFR) and hypofractionated radiotherapy (HFR) in patients with persistent postprostatectomy PSA who received salvage radiotherapy to prostate bed. Methods Single institution retrospective chart review was performed after Institutional Review Board approval. Between May 2012 and December 2016, 147 patients received salvage postprostatectomy radiotherapy. PSA failure-free and metastasis-free survival were calculated using Kaplan–Meier method. Cox regression analysis was performed to test association of fractionation regimen and other clinical factors with treatment outcomes. Early and late toxicity was assessed using Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0. Results Sixty-nine patients who had persistent PSA (≥ 0.1 ng/mL) after prostatectomy were identified. Median follow-up was 67 months (95% CI 58–106 months, range, 8–106 months). Thirty-six patients (52.2%) received CFR, 66 Gy in 33 fractions, 2 Gy per fraction, and 33 patients (47.8%) received HFR, 52.5 Gy in 20 fractions, 2.63 Gy per fraction. Forty-seven (68%) patients received androgen deprivation therapy (ADT). 5-year PSA failure- and metastasis-free survival rate was 56.9% and 76.9%, respectively. Thirty patients (43%) experienced biochemical failure after salvage radiotherapy and 16 patients (23%) experienced metastatic relapse. Nine patients (13%) developed metastatic castration-resistant disease and died of advanced prostate cancer. Median PSA failure-free survival was 72 months (95% CI; 41–72 months), while median metastasis-free survival was not reached. Patients in HFR group were more likely to experience shorter PSA failure-free survival when compared to CFR group (HR 2.2; 95% CI 1.0–4.6, p = 0.04). On univariate analysis, factors significantly associated with PSA failure-free survival were radiotherapy schedule (CFR vs HFR, HR 2.2, 95% CI 1.0–4.6, p = 0.04), first postoperative PSA (HR 1.02, 95% CI 1.0–1.04, p = 0.03), and concomitant ADT (HR 3.3, 95% CI 1.2–8.6, p = 0.02). On multivariate analysis, factors significantly associated with PSA failure-free survival were radiotherapy schedule (HR 3.04, 95% CI 1.37–6.74, p = 0.006) and concomitant ADT (HR 4.41, 95% CI 1.6–12.12, p = 0.004). On univariate analysis, factors significantly associated with metastasis-free survival were the first postoperative PSA (HR 1.07, 95% CI 1.03–1.12, p = 0.002), seminal vesicle involvement (HR 3.48, 95% CI 1.26–9.6,p = 0.02), extracapsular extension (HR 7.02, 95% CI 1.96–25.07, p = 0.003), and surgical margin status (HR 2.86, 95% CI 1.03–7.97, p = 0.04). The first postoperative PSA (HR 1.04, 95% CI 1.00–1.08, p = 0.02) and extracapsular extension (HR 4.24, 95% CI 1.08–16.55, p = 0.04) remained significantly associated with metastasis-free survival on multivariate analysis. Three patients in CFR arm (8%) experienced late genitourinary grade 3 toxicity. Conclusions In our experience, commonly used hypofractionated radiotherapy regimen was associated with lower biochemical control compared to standard fractionation in patients with persistent PSA receiving salvage radiotherapy. Reason for this might be lower biological dose in HFR compared to CFR group. However, this observation is limited due to baseline imbalances in ADT use, ADT duration and Grade Group distribution between two radiotherapy cohorts. In patients with persistent PSA post-prostatectomy, the first postoperative PSA is an independent risk factor for treatment failure. Additional studies are needed to corroborate our observations.

Purpose/objective: The association of 3D Conformal External Beam Radiotherapy (3D-CEBRT) with adjuvant Androgen Deprivation Therapy (ADT) proved to treat patients with intermediate- and high-risk localized prostate cancer (IR and HR). However, older patients were underrepresented in literature. We aimed to report the oncological results and morbidity 3D-CEBRT +ADT in ≥80 years patients. Material and Methods: From June 1998 to July 2017, 101 patients ≥80 years were included in a tertiary center. The median age was 82 years. ADT was initiated 3 months prior 3D-CEBRT in all patients, with a total duration of 6 months for IR prostate cancer (group A; n = 41) and 15 months for HR prostate cancer (group B; n = 60). Endpoints included overall survival (OS), metastasis-free survival (DMFS), biochemical recurrence-free survival (BRFS) and toxicity. Results: Five years-OS was 95% and 86.7% in groups A and B, respectively. Cardiovascular events occurred in 22.8% of ≥80 years patients with no impact on OS. In the multivariate analysis, age <82 years, Karnofsky index and normalization of testosterone levels were significantly associated with better OS. Conclusion: Age ≥80 years should not be a limitation for the treatment of IR and HR prostate cancer patients with 3D-CEBRT and ADT, but cardiovascular monitoring and prevention are mandatory.

TPS5098 Background: Radiation therapy (RT) to the prostate bed and pelvic nodes with short-term androgen deprivation therapy (STAD) is considered a standard of care (SOC) salvage therapy (ST) paradigm for prostate cancer (PC) patients (pts) with post-prostatectomy (RP) biochemical recurrence (BCR). Fluciclovine-PET/CT imaging is FDA-approved in this setting, with improved accuracy for detection of metastases not identified with conventional imaging (CIM). Given PET's greater sensitivity and specificity, its findings are increasingly but variably applied to justify modification or omission of SOC therapies without high-level evidence of clinical benefit. PET may help identify candidates for local or systemic treatment intensification of the otherwise non-tailored SOC approach. Improved systemic control and disease detection with molecular imaging have led to increasing use of focally ablative metastasis-directed RT, to delay or enhance systemic therapy through increased local control. There is also interest in earlier use of systemic therapy; apalutamide (Apa) is a nonsteroidal antiandrogen with established efficacy in improving overall and radiographic progression-free survival (PFS) for non-metastatic castration-resistant and metastatic castration-sensitive PC. This study will evaluate whether pts with PET-detected lesions benefit from such local or systemic treatment intensification approaches. Methods: PC pts with post-RP BCR (PSA>0.5ng/mL; >0.2ng/mL if within 12 mos of RP) and no metastases on CIM who are candidates for SOC ST (RT to prostate bed and pelvic nodes with STAD) are eligible. Prior to study registration, pts undergo SOC baseline PET (18F-fluciclovine but PSMA radiotracers permitted pending commercial availability). Based on institutional clinical interpretation of the SOC PET, pts will be placed in Cohort 1 (PET-negative) or 2 (PET-positive for extra-pelvic metastases). Cohort 1 will be randomized to SOC ST +/- Apa for 6 months and Cohort 2 will be randomized to SOC ST and Apa +/- metastasis-directed RT to PET-positive lesions. The primary endpoint is PFS, defined as time from randomization to radiographic progression on CIM, symptomatic disease or death. Primary objectives are to evaluate whether addition of Apa to SOC ST and addition of metastasis-directed RT to SOC ST and Apa could prolong PFS in Cohorts 1 and 2, respectively. For Cohort 1, 480 pts will be randomized with 85% power to distinguish 5-year PFS rate of 90% (Apa arm) vs. 80% (SOC arm) using one-sided stratified log-rank test with type I error of 0.025. For Cohort 2, 324 pts will be randomized with 85% power to distinguish 5-year PFS rate of 76.5% in the experimental arm from 61.5% in the control arm. Secondary endpoints include overall and event-free survival, toxicity, and PET progression. Clinical trial information: NCT04423211.

Objective: This study aimed to investigate the relationship between obesity and pathologic features and biochemical recurrence in patients with prostate cancer (PCa) undergoing radical prostatectomy (RP) after neoadjuvant hormonal therapy (NHT). Methods: A total of 422 consecutive patients with clinically localized PCa who received NHT before RP were retrospectively analyzed. Unconditional multiple logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) regarding probability. A receiver operating characteristic (ROC) curve was used to assess the efficacy of the predictive variables. Castration resistance free survival curves were obtained using the Kaplan-Meier method, and were compared using the log-rank test. Results: Being overweight was associated with an increased risk of positive margins (OR 2.281; 95% CI 1.292–4.028) after adjusting for potential confounders. The area under the ROC curve for overweight patients was larger than that for patients in the normal weight range. There was no significant difference between the overweight and normal weight groups regarding castration resistance free survival. Conclusions: Being overweight was associated with positive margins in patients with PCa undergoing RP after NHT.

Image Guided Radiotherapy

External beam radiotherapy (EBRT) is one of the curative treatment options for prostate cancer patients. The aim of this treatment option is to irradiate tumor tissue, while sparing normal tissue as much as possible. Frequent imaging during the course of the treatment (image guided radiotherapy) allows for determination of the location and shape of the prostate (target) and of the organs at risk. This information is used to increase accuracy in radiation dose delivery resulting in better tumor control and lower toxicity. Ultrasound imaging is harmless for the patient, it is cost-effective, and it allows for real-time volumetric organ tracking. For these reasons, it is an ideal technique for image guidance during EBRT workflows. Review papers have been published in which the use of ultrasound imaging in EBRT workflows for different cancer sites (prostate, breast, etc.) was extensively covered. This new review paper aims at providing the readers with an update on the current status for prostate cancer ultrasound guided EBRT treatments.
