Urotronic, Inc. said it has received an investigational device exemption approval from the FDA to begin its U.S. pivotal study for the Optilume BPH Catheter System.

Three novel androgen receptor inhibitors provide an embarrassment of riches when it comes to treatment options for nmCRPC patients, but there are still questions to be answered-including the extent of these drugs’ clinical benefit.

The FDA has approved apalutamide (Erleada) for the treatment of patients with metastatic castration-sensitive prostate cancer, a new indication for the next-generation androgen receptor inhibitor.

A preliminary study of the use of salvage lymph node dissection in patients with nonmetastatic, castration-resistant prostate cancer indicates the potential to delay disease recurrence as well as the use of systemic therapies through this approach.

A new study suggests that prostate-specific membrane antigen positron emission tomography/computed tomography may be a highly beneficial tool for initial staging of high-risk and high-intermediate-risk prostate cancer.

Researchers say the use of apalutamide (Erleada) in patients with high-risk, nonmetastatic castration-resistant prostate cancer improves metastasis-free survival in patients who have previously undergone radical prostatectomy or external radiotherapy-regardless of the type of treatment they received.

"The last several years have been particularly exciting in the area of metastatic castrate-resistant prostate cancer," writes J. Brantley Thrasher, MD.

Analyses of data collected in PROCEED, a large real-world registry, corroborate phase III study findings demonstrating that sipuleucel-T (Provenge) treatment for metastatic castrate-resistant prostate cancer has a particular benefit for improving overall survival in African-American men.

A 63-year-old African-American male presents to the emergency department with sudden onset of painless gross hematuria for one day. He reports dark red urine with clots causing occasional dysuria, difficulty emptying, and light-headedness.

Patients with CVD taking abiraterone or enzalutamide have a 43% higher risk of hospitalization, according to a recent study.

A survey of low-risk prostate cancer patients found men who choose active surveillance over definitive treatment have similar mental health outcomes.

Study findings have implications for noninvasive markers to predict the course of UCC

Analyses based on number needed to treat benefit show that the overall survival benefit is similar when using abiraterone acetate (ZYTIGA), enzalutamide (XTANDI), or sipuleucel-T (Provenge) to treat men with chemotherapy-naïve metastatic castration-resistant prostate cancer. The data, however, favor sipuleucel-T for having the lowest direct cost.

Pembrolizumab (Keytruda) is showing encouraging antitumor activity in an ongoing phase II study including patients with high-risk, nonmuscle-invasive bladder cancer that is unresponsive to bacillus Calmette-Guérin treatment.

"There appears to be a strikingly high likelihood of increased morbidity and poor outcomes in patient who are not receiving definitive therapy," writes Badar M. Mian, MD.

Mark Frydenberg, MD, of Australia's Monash University, discusses whether multiparametric MRI is ready to be used as a screening modality for prostate cancer.

In this interview, Mark Frydenberg, MD, discusses the evolution of PET scanning, its clinical indications, its advantages and drawbacks, and key questions that remain about its use.

"While much work is still to be done, we have excellent evidence that there is a beneficial class-like effect for the androgen inhibitors enzalutamide, apalutamide, and darolutamide used within the current definition of men with M0 CPRPC," write Michael Cookson, MD, and Tony Rodriguez, MD.

Neoadjuvant chemohormonal therapy warrants consideration in the management of men undergoing radical prostatectomy for clinically localized high-risk prostate cancer, said James Eastham, MD, at the American Society of Clinical Oncology annual meeting in Chicago.

Results of a phase III trial show the benefit of darolutamide (Nubeqa) in reducing the risk of metastases or death compared with placebo in men with nonmetastatic castration-resistant prostate cancer.

Race does not affect oncologic response to treatment with docetaxel (Taxotere)/prednisone in men with metastatic castrate-resistant prostate cancer, according to research presented at the American Society of Clinical Oncology annual meeting in Chicago.

Adding enzalutamide (XTANDI) to androgen deprivation therapy significantly improves outcomes for men with metastatic hormone-sensitive prostate cancer regardless of whether they received prior chemotherapy.

The largest analysis of active surveillance for metastatic renal cell carcinoma presented to date shows that a proportion of patients can be safely observed without need to start systemic therapy right away.

18F-DCFPyL PET/CT imaging demonstrated excellent performance in identifying regional or distant metastases in men with prostate cancer in the prospective OSPREY study.

"While the safety and feasibility of the renal mass biopsy procedure has been established, if or when to obtain the biopsy remains a topic for active discussion," writes Badar M. Mian, MD.
