Prostate Cancer

Although androgen deprivation therapy has a survival benefit for patients with high-risk and locally advanced prostate cancer, it is associated with substantial safety concerns, and mixed data exist regarding whether it causes clinically significant depression.

Despite limited data comparing stereotactic body radiation therapy to standard or hypofractionated radiotherapy with regards to long-term clinical outcomes and toxicity profiles, the data are promising and appropriately selected patients can be offered such an approach off-protocol.

Researchers are hoping the results of a late-stage efficacy and safety study of apalutamide in patients with high-risk, localized, or locally advanced prostate cancer who are receiving primary radiation therapy will demonstrate an improvement in metastasis-free survival.

A combination regimen involving abiraterone acetate (Zytiga) and low-dose prednisone demonstrated a median time to radiographic progression of 41.4 months, as well as a median time to prostate-specific antigen progression of 28.7 months, in men with nonmetastatic castration-resistant prostate cancer.

Christopher E. Barbieri, MD, PhD, surgeon, researcher in prostate cancer genomics, Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine and New-York Presbyterian, discusses the implications of SPOP mutations in patients with prostate cancer.

The radioactive imaging agent, fluciclovine F18 (Axumin), was approved by the FDA for use in positron emission tomography scans in men with suspected recurrence of prostate cancer whose prostate-specific antigen levels rise following prior treatment.

Using the Decipher Prostate Cancer Classifier assay to predict which patients might respond to hormonal therapy has resulted in the discovery and validation of an adjuvant androgen-deprivation therapy resistance signature.

Luke Nordquist, MD, discusses a study investigating a higher dose of radium-223 dichloride (Xofigo) in patients with metastatic castration-resistant prostate cancer and the ongoing potential of the agent in treating the disease.

Jim Hu, MD, MPH, director of the LeFrak Center for Robotic Surgery at NewYork-Presbyterian/Weill Cornell Medical Center and the Ronald Lynch Chair of Urologic Oncology at Weill Cornell Medical College, discusses critical flaws in the landmark PLCO trial in prostate cancer.

Oliver Sartor, MD, discusses current research with biomarkers in prostate cancer, as well as how some treatments may be utilized as both single agents and in combination.

Herbert Lepor, MD, discusses the advent of the MRI-US fusion targeted biopsy and what impact it could have on the field of assessing prostate cancer risk.

Results of a multi-institutional prospective study showed that treatment with unilateral high-intensity focused ultrasound led to eradication of all clinically significant cancer in the treated lobe for 94% of patients with early prostate cancer.
