A recent publication in Science demonstrates the ability of prostate cancer cells to switch lineages from one that is dependent on androgen signaling to a cell type that is not. Known as lineage plasticity, this phenomenon is driven by the transcription factor SOX2 in RB1 and TP53-deficient prostate cancer.
BACKGROUND - The TMPRSS2-ERG gene fusion is detected in approximately half of primary prostate cancers (PCa) yet the prognostic significance remains unclear. We hypothesized that ERG promotes the expression of common genes in primary PCa and metastatic castration-resistant PCa (CRPC), with the objective of identifying ERG-associated pathways, which may promote the transition from primary PCa to CRPC.

Recent trends in cancer therapy have begun emphasizing the use of precision medicine, especially genetic tools, in the evaluation of malignancies and decision-making. Prostate cancer is a malignancy where the benefits and utility of screening and early treatment are still heavily controversial.
Management of metastatic castration-resistant prostate cancer has changed markedly over the last decade with major shifts in the treatment paradigm, although ultimately still will progress despite currently available therapies.
During the last few years, the therapeutic armamentarium of castration resistant prostate cancer (mCRPC) has been enriched with the introduction of new effective therapies with proved survival benefit and quality of life gain, including cabazitaxel, abiraterone, enzalutamide, and Radium-223.
Although recent advances in the treatment of castration-resistant prostate cancer (CRPC) have significantly improved patient outcomes, advanced prostate cancer is still associated with substantial morbidity and mortality, particularly in patients who develop resistance after multiple lines of therapy.
The androgen receptor (AR) is the classical target for prostate cancer prevention and treatment, but more recently estrogens and their receptors have also been implicated in prostate cancer development and tumor progression.
Prostate cancer (PC) is one of the most common cancers worldwide. The observed variability in progression and responses to the same treatment between patients underlie the genetic heterogeneity of the disease.

Antiandrogen withdrawal syndrome (AAWS), manifested as a prostate-specific antigen (PSA) decline after discontinuation of a first-generation antiandrogen has been well characterized. The objective of the present study was to assess the incidence of AAWS with enzalutamide in men with metastatic castration-resistant prostate cancer.
To investigate whether IL-6 signaling affects the susceptibility of castration resistant prostate cancer (CRPC) cells to cytotoxic action of natural killer (NK) cells, CRPC cell lines (having different IL-6 level) were developed by lentiviral transduction.
The underlying mechanisms responsible for the development of castration-resistant prostate cancer (CRPC) in patients who have undergone androgen deprivation therapy are not fully understood. This is the first study to address whether β2-adrenergic receptor (ADRB2)- mediated signaling may affect CRPC progression in vivo.
Androgen deprivation therapy (ADT) is commonly given to men with prostate cancer. Both its benefits as well as its adverse effects are a direct consequence of sex steroid withdrawal. While ADT improves oncologic outcomes in appropriately selected men, it is associated with adverse effects, including accelerated bone loss leading to increased fracture risk, and with metabolically unfavorable body composition changes that predispose to diabetes and may increase cardiovascular risk.
Herein, we report the clinical outcomes of a multicenter study evaluating the role of SBRT in a cohort of patients affected by oligoprogressive castration-resistant prostate cancer (CRPC).
This is a retrospective multicenter observational study including eleven centers.
With almost 30,000 deaths per year, prostate cancer is the second-leading cause of cancer-related death in men. Androgen Deprivation Therapy (ADT) has been the corner stone of prostate cancer treatment for decades.
