Abstract Many different therapeutic options are available for locally recurrent prostate cancer (PCa). However, standard treatment has not yet been established. We conducted a partial prostate re-irradiation (PPR) program for the treatment of isolated and limited-size intraprostatic recurrences, in patients who previously underwent external beam radiation therapy (EBRT) as primary treatment for prostatic cancer (PCa). The analysis of this experience in terms of feasibility, toxicity, and efficacy is reported. The inclusion criteria of this retrospective analysis were: previous definitive EBRT, evidence of biochemi...

In this study, we evaluated prostate multiparametric MRI (mpMRI) before and after neoadjuvant enzalutamide plus ADT. EXPERIMENTAL DESIGN: Men with localized intermediate- or high-risk prostate cancer underwent a baseline mpMRI and mpMRI-targeted biopsy followed by a second mpMRI after 6 months of enzalutamide and ADT prior to RP. Specimens were sectioned in the same plane as mpMRI using patient-specific 3D-printed molds to permit mpMRI-targeted biopsies to be compared to the same lesion from the RP. Specimens were analyzed for imaging and histologic correlates of response. RESULTS: Of 39 patients enrolled, 36 com...

Stereotactic body radiation therapy (SBRT) is an effective, convenient, and cost-effective definitive radiotherapy option for localized prostate cancer and is supported by the National Comprehensive Cancer Network (NCCN) for low-, intermediate-, and high-risk disease.[1 –3] This technique exploits the estimated low α/β ratio for prostate cancer of approximately 1.5-3.0 Gy, which denotes a greater sensitivity to hypofractionation.[4–7] The use of SBRT for definitive treatment of prostate cancer is increasing rapidly,[8–9] yet the dose-response and optimal do se are still uncertain.

Hematuria of prostatic origin has multiple etiologies including benign prostatic hyperplasia (BPH), iatrogenic urological trauma, prostate cancer, and radiation therapy. Hematuria secondary to benign prostatic hyperplasia (BPH) can occur because of the increased vascularity of the primary gland, itself, or because of the vascular re-growth following a transurethral resection of the prostate. Prostatic hematuria usually resolves with conservative measures; however, refractory hematuria of prostatic origin (RHPO) may require hospitalization with treatment with blood transfusions, repeated indwelling urinary catheterization, ...

CONCLUSION: Prostate cancer treatment choices differ substantially between men diagnosed in private and public health services in Victoria. These differences are not explained by disease severity or comorbidity. PMID: 32996611 [PubMed - as supplied by publisher]

Prostate cancer is the most common malignancy in North American males and the second leading cause of cancer death. External beam radiation therapy plays an important role in the clinical management of prostate cancer of various stages. Currently, image-guided target localization for intensity-modulated radiation therapy (IMRT) of prostate cancer has become a routine procedure, and plays an essential role in dose escalation and hypo-fractionation clinical trials, especially for those that employ stereotactic body radiation therapy (SBRT) techniques.

The main objective of this prospective study was to determine the impact of multiphasic acquisition of 68Ga-PSMA PET/CT in the detection of recurrent prostate cancer in the early stage of biochemical recurrence with a prostate-specific antigen (PSA) level of less than 1 ng/mL. Also, 68Ga-PSMA PET/CT positivity was correlated with clinical parameters for the assessment of predictive markers. Methods: A prospective monocentric study was conducted on 135 prostate cancer patients with biochemical recurrence and a PSA level of less than 1 ng/mL. All patients had undergone initial prostatectomy, with additional radiation therapy...

Douglas G McNeel Metastatic castration-resistant prostate cancer (mCRPC) is a challenging disease to treat, with poor outcomes for patients. One antitumor vaccine, sipuleucel-T, has been approved as a treatment for mCRPC. DNA vaccines are another form of immunotherapy under investigation. DNA immunizations elicit antigen-specific T cells that cause tumor cell lysis, which should translate to meaningful clinical responses. They are easily amenable to design alterations, scalable for large-scale manufacturing, and thermo-stable for easy transport and distribution. Hence, they offer advantages over other vaccine formul...
