Prostate brachytherapy, either alone or in combination with external beam radiation, is associated with longer overall survival in men with favorable pathologic Group 4 (Gleason score 8) prostate cancer
Conventional prostate cancer risk stratification results in considerable heterogeneity within each prognostic group. Men with pathologic grade Group 4 (Gleason score 8) but otherwise low-risk features have been identified as a favorable subset of high-risk prostate cancer. Given recent randomized data supporting improved cancer outcome with brachytherapy in intermediate- and high-risk prostate cancer, we sought to evaluate brachytherapy utilization and overall survival (OS) for these patients.
In this study we evaluate the lesion detection efficacy of18F-DCFPyL PET/CT in patients with BCR and determine the detection efficacy as a function of their PSA value.MethodsA total of 248 consecutive patients were evaluated and underwent scanning with18F-DCFPyL PET/CT for BCR between November 2016 and 2018 in two hospitals in the Netherlands. Patients were examined after radical prostatectomy (52%), external-beam radiation therapy (42%) or brachytherapy (6%). Imaging was performed 120 min after injection of a median dose of 311 MBq18F-DCFPyL.ResultsIn 214 out of 248 PET/CT scans (86.3%), at least one lesion sug...
CONCLUSIONS: In this systematic review and meta-analysis, we did not observe higher rate of BCR after TRT for nonmetastatic CaP patients after definitive local therapy. Based on these data, others and we have outlined a phase I/II trial assessing the safety and benefits of TRT in select men with secondary symptomatic hypogonadism who have no active disease after definitive local CaP therapy with curative intent.

To evaluate the biochemical freedom from failure (bFFF) by risk group and treatment modality and the predictive factors of bFFF by risk group in patients with prostate cancer undergoing permanent seed implantation (PI) with or without external beam radiation therapy (EBRT) in a nationwide prospective cohort study (Japanese Prostate Cancer Outcome Study of Permanent Iodine-125 [I-125] Seed Implantation) in Japan during the first 2 years.
Conclusions: There is an almost equal split among North American GU expert radiation oncologists regarding the appropriateness to consider moderately hypofractionated EBRT as a new standard of care in management of patients with prostate cancer. Physicians who embrace brachytherapy may be more inclined to support moderate hypofractionated regimen for EBRT. It is unclear whether reports with longer follow-ups will impact this balance, or whether national care and reimbursement policies will drive the clinical decisions. In the day and age of patient - centered care delivery, patients should receive an objective recommendati...
Conclusions: BT was effective as a definitive treatment modality for prostate cancer, and its endpoints and toxicities were comparable to those of the main series in the literature.

592Objectives: 18F-rhPSMA-7 is a new theranostic PSMA-targeting agent which allows fast radiolabeling with 18F and radiometals. This retrospective analysis investigates the efficacy of 18F-rhPSMA-7 PET/computed tomography (CT) in patients with biochemical recurrence of prostate cancer following curative-intent primary treatment with external beam radiotherapy (EBRT) or brachytherapy. Methods: Datasets from patients with non-castrate biochemical recurrence of prostate cancer after treatment with EBRT or brachytherapy who underwent 18F-rhPSMA-7 PET/CT at either the Technical University Munich or Ludwig-Maximillian University...
CONCLUSION: We found no statistically significant difference in survival between RP and EBRT+BT. EBRT and brachytherapy had higher mortality, respectively, compared to RP. When including only radiotherapy patients who received ADT and, in the case of EBRT, a total dose ≥ 7920 cGy, there was no statistically significant difference in survival when comparing RP to EBRT or brachytherapy. These findings should be prospectively studied. PMID: 31109836 [PubMed - as supplied by publisher]
