Does “AR gain” affect responses to drugs like abiraterone in men with CRPC?

Perhaps unsurprisingly, it appears to be true that “AR gain” (see below) does indeed lower overall survival (OS) and progression-free survival (PFS) rates among men with castration-resistant prostate cancer (mCRPC). … READ MORE …

CAR-T used in treatment of two men with mCRPC at UPenn

On a CureTalks conversation earlier today with Dr. Carl June of the University of Pennsylvania (UPenn), we learned that his team had very recently treated two men with metastatic, castration-resistant prostate cancer (mCRPC) using chimeric antibody receptor T-cell therapy (CAR-T). … READ MORE …

CAR-T in the treatment of cancer: a CureTalks telecon

On November 15, our friends at CureTalks will hold a telecon on which there will be a discussion about the current and potential future uses of CAR-T in the treatment of cancer with Prof. Carl June of the University of Pennsylvania. … READ MORE …

New test for abiraterone- and enzalutamide-resistant forms of prostate cancer

A group at The Institute for Cancer Research and The Royal Marsden Hospital in the UK — along with other European colleagues — has come up with a new, relatively low-cost test that seems to be able to identify men with advanced forms of prostate cancer who are more or less likely to respond well to treatment with drugs like abirateone acetate and enzalutamide. … READ MORE …

Data from the first really large trial of CAR-T in treatment of lymphoma

As yet, there has been no serious clinical exploration of whether the new types of CAR-T treatment can be applied to patients with either prostate cancer or any other form of solid tumor. … READ MORE …

ROR-γ: a new way to suppress androgen receptor expression?

Most of our readers will be familiar with the idea that progression of prostate cancer over time is associated with the expression of  androgen receptors (ARs) in prostate cancer tissue. … READ MORE …

Can the ex-Aragon team pull off a repeat with another new drug for mCRPC

According to an article by Alex Lash on the Xconomy web site, a start-up biotech company in South San Francisco called ORIC Pharmaceuticals will — at least initially — be highly focused on new drug therapies for men with very late-stage prostate cancer. … READ MORE …

The role of liquid biopsies in management of advanced prostate cancer

A newly published paper in Science Translational Medicine has added to our understanding of the future potential of liquid biopsies (e.g., blood, plasma, and similar samples) in the management of progressive forms of prostate cancer. … READ MORE …

Early identification of androgen receptor gene amplification and prostate cancer risk

Historically, it has generally been assumed that androgen receptor gene amplification was a result of androgen deprivation therapy (ADT) and occurred in some 20 to 30 percent of men with castration-resistant prostate cancer (CRPC). However, … READ MORE …

AR gene amplification and risk for CRPC

An article just published in the British Journal of Cancer, has proposed that androgen receptor (AR) gene amplification may be a prime cause of treatment failure in a subset of men with progressive prostate cancer. … READ MORE …

Does normal expression of SPOP prevent development of many prostate cancers?

Researchers from the Mayo Clinic in Rochester, MN, are claiming that they have made a series of four important discoveries related to the role of a protein called “speckle-type POZ protein” (SPOP) and its involvement in the development of prostate cancer. … READ MORE …

New review of current practice in use of LHRH receptor agonists and antagonists

The full text of a recent review on the use of LHRH receptor agonists (e.g., leuprolide acetate, goserelin acetate) asnd LHRH receptor antagonists (e.g., degarelix) has recently been published by Shore et al. in Prostate Cancer and Prostatic Diseases. The full text of the article is also available on line on the Medscape Oncology web site.

GRK5 and the aggressive growth of prostate cancer tumors

An article published on line in the Journal of Urology last Friday suggests that an enzyme known as G-protein-coupled receptor kinase 5 or GRK5 may have an important role in the regulation of the growth of prostate cancer. … READ MORE …

PDGFR inhibition accelerates disease progression in men with mCRPC

A while back now the research group at M. D. Anderson Cancer Center initiated a Phase II clinical trial of a drug called tandutinib in the treatment of men with metastatic, castration-resistant prostate cancer (mCRPC) who had already had taxane-based chemotherapy. … READ MORE …
