Reversal of PSA progression on abiraterone acetate through the administration with food in men with metastatic castration-resistant prostate cancer

Prostate Cancer and Prostatic Diseases
J T StoverAndrew J Armstrong

Abstract

Owing to efficacy and tolerability, abiraterone acetate (AA) is a leading treatment for men with metastatic castration-resistant prostate cancer. Increased serum concentrations of AA, such as by taking AA with food, may lead to the inhibition of additional enzymes in the androgen synthesis pathway implicated in castration-resistant prostate cancer progression. Medical records of men with metastatic castration-resistant prostate cancer (mCRPC) who received AA between 1 April 2011 and 31 December 2013 were retrospectively reviewed. The primary outcome was the percent of men with a rising PSA on AA who experienced any PSA decline within 3 months after changing the administration of AA from without food to with food. Secondary outcomes were median time on AA therapy in men who received AA therapy without food versus those that switched administration from without food to with food at PSA progression, and the percent of men who experienced any decline in serum testosterone concentration, and the rate of adverse events observed while taking AA with food. Nineteen men who switched AA administration from without food to with food and 41 patients who administered AA without food only were included in the study. Of those patients who too...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
