The therapeutic landscape of metastatic castration-resistant prostate cancer (mCRPC) has been revolutionized by the arrival of multiple novel agents in the past 2 years. Immunotherapy in the form of sipuleucel-T, androgen axis inhibitors, including abiraterone acetate and enzalutamide, a chemotherapeutic agent, cabazitaxel, and a radiopharmaceutical, radium-223, have all yielded incremental ext...

Currently, it is recommended that prostate cancer be detected by digital rectal palpation and prostate specifi c antigen (PSA) elevation. TRUS coupled with ultrasound-guided biopsies might become the most appealing staging technique for early diagnosed prostate cancer. To promote earlier diagnosis, better PSA thresholds need to be defi ned, with a clear freePSA threshold. This could be compleme...

The androgen receptor (AR) is essential for development of the male gender and in the growth of the majority of prostate cancers. Agonists as well as most antagonists induce translocation of the receptor to the nucleus, whereas only agonists can activate AR function. Antagonists are therefore used in the therapy of metastasized prostate cancer. To obtain insight into the mechanism by which anta...

background and objective: determination of hormone receptor status in the management of breast cancer is well-established. the aim of this study was to evaluate the frequency of androgen receptor (ar) expression in invasive ductal carcinoma of breast. materials and methods: for this purpose, 55 cases of invasive ductal breast carcinoma were examined using a monoclonal antibody against ar on for...

The treatment landscape for prostate cancer has changed remarkably in the last few years, with several US FDA-approved drugs and a promising pipeline of new agents. The current paradigm of treatment for advanced prostate tumors, which are androgen dependent, is hormone ablation therapy. This can be achieved chemically through LHRH agonists or antagonists, or surgically through orchiectomy. Most...

The two most common muscle wasting diseases in adults are sarcopenia and cachexia. Despite differences in their pathophysiology, it is believed that both conditions are likely to respond to drugs that increase muscle mass and muscle strength. The current gold standard in this regard is exercise training. This article provides an overview of candidate drugs to treat muscle wasting disease that a...

Endocannabinoids have been implicated in cancer. Increasing endogenous 2-arachidonoylglycerol (2-AG) by blocking its metabolism inhibits invasion of androgen-independent prostate cancer (PC-3 and DU-145) cells. Noladin ether (a stable 2-AG analog) and exogenous CB1 receptor agonists possess similar effects. Conversely, reducing endogenous 2-AG by inhibiting its synthesis or blocking its binding...
