PURPOSE OF REVIEW: Personalizing prostate cancer therapy requires germline and tumor molecular tests that predict who will respond to specific treatments and who may not. The review covers molecular testing of DNA damage response pathways, the first biomarker-driven precision target with clinical utility for treatment selection in patients with castration resistant prostate cancer (CRPC). RECENT FINDINGS: Recurrent somatic and germline variants cause deficiency of the mismatch repair (MMR) or homologous recombination (HR) pathways in about a quarter of CRPC patients...

PURPOSE OF REVIEW: Recurrence post definitive local therapy by prostatectomy or radiation therapy is often detected via rise in serum prostate-specific antigen (PSA) levels; however, PSA rise does not localize the disease. Distinguishing local versus distant recurrence guides whether to choose subsequent local versus systemic therapy. The purpose of this article is to review imaging for prostate cancer recurrence post local therapy. RECENT FINDINGS: Among imaging modalities, multiparametric MRI (mpMRI) is commonly used to assess for local recurrence...

PURPOSE OF REVIEW: This review is designed to highlight recent research examining treatment progress in advanced prostate cancer while identifying ongoing challenges to clinical outcomes. RECENT FINDINGS: Recent randomized trials suggest an overall survival advantage to treating some men with newly identified metastatic prostate cancer with a "triplet" of androgen deprivation therapy, docetaxel, and an androgen receptor axis-targeted agent. Questions remain about which men are best served by these combinations...

In recent years, we witnessed significant changes in the way we diagnose prostate cancer and the options for management of low risk localized prostate cancer. This review discusses today's approach to men with elevated PSA. The use of biomarkers and or prostate MRI is strongly recommended prior to the decision on a biopsy. Following a suspicious finding in MRI the best approach is MRI-guided biopsy. Traditionally, biopsies are performed transrectally but the emerging transperineal biopsy has considerable advantage...

Kidney, bladder, and prostate cancer are the three major tumor types of the urologic system that seriously threaten human health. Circular RNAs (CircRNAs), special non-coding RNAs with a stabile structure and a unique back-splicing loop-forming ability, have received recent scientific attention. CircRNAs are widely distributed within the body, with important biologic functions such as sponges for microRNAs, as RNA binding proteins, and as templates for regulation of transcription and protein translation. The abnormal expression of circRNAs in vivo is significantly associated with the development of urologic tumors...

It is unclear whether cancer patients enrolled in clinical trials have improved outcomes compared with non-study patients. We compared prostate cancer-specific mortality (PCSM) in patients in a real-world setting (SEER-Medicare database) versus on a trial (NRG/RTOG 0521). The 7-year freedom from PCSM was superior in trial patients (92.4% vs. 88.1%, sHR = 1.77 [95% CI 1.05-2.97], P = 0.03). Black trial patients had significantly superior freedom from PCSM than Black real-world patients (sHR 6...

BACKGROUND: Simple prostatectomy has been established as a management option for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) with glands larger than 80cc (1). Robotic-assisted simple prostatectomy (RASP) has been established as a safe and effective management option. This has been reported in multiple studies comparing it with the open approach where no statistically significant differences in complication rates have been found (2). The intrafascial approach is intended to add multiple benefits, such as not requiring continuous bladder irrigation and resection of a larger percentage of the adenoma, potentially leading to a lower reoperation rate and diagnosis of prostate cancer in patients in which this was missed preoperatively (3)...

High intensity focused ultrasound (HIFU) is a non-invasive and non-ionizing sonic energy-based therapeutic technology for inducing thermal and non-thermal effects in tissues. Depending on the parameters, HIFU can ablate tissues by heating them to >55 °C to induce denaturation and coagulative necrosis, improve radio- and chemo-sensitizations and local drug delivery from nanoparticles at moderate hyperthermia (~41-43 °C), and mechanically fragment cells using acoustic cavitation (also known as histotripsy)...

Cancer cells proliferate, differentiate and migrate by repurposing physiological signalling mechanisms. In particular, altered calcium signalling is emerging as one of the most widespread adaptations in cancer cells. Remodelling of calcium signalling promotes the development of several malignancies, including prostate cancer. Gene expression data from in vitro, in vivo and bioinformatics studies using patient samples and xenografts have shown considerable changes in the expression of various components of the calcium signalling toolkit during the development of prostate cancer...

Conventional treatment of prostate cancer (PCa) uses androgen-deprivation therapy (ADT) to inhibit androgen receptor (AR) signaling-driven tumor progression. ADT-induced PCa recurrence may progress to an AR-negative phenotype with neuroendocrine (NE) histologic features, which are associated with metabolic disturbances and poor prognoses. However, the metabolic pathways that regulate NE differentiation (NED) in PCa remain unclear. Herein, we show a regulatory mechanism in NED-associated metabolism dysfunction induced by ADT, whereby overexpression of pyruvate kinase L/R (PKLR) mediates oxidative stress through upregulation of reactive oxygen species modulator 1 (ROMO1), thereby promoting NED and aggressiveness...
