Androgen-deprivation therapy-induced aggressive prostate cancer with neuroendocrine differentiation

Androgen-deprivation therapy-induced aggressive prostate cancer with neuroendocrine differentiation

Most prostate cancers (PCas) are classified as acinar type (conventional) adenocarcinoma which are composed of tumor cells with luminal differentiation including the expression of androgen receptor (AR) and prostate-specific antigen (PSA). There are also scattered neuroendocrine (NE) cells in every case of adenocarcinoma. The NE cells are quiesecent, do not express AR or PSA, and their function...

[Androgen-deprivation therapy in the management of neuroendocrine prostate cancer].

BACKGROUND Prostatic neuroendocrine carcinomas comprise <1% of all prostate neoplasms, and approximately 200 cases have been reported in the literature. We undertook this study to describe the experience in the management of prostatic neuroendocrine carcinoma with androgen-deprivation therapy (ADT). METHODS We designed a retrospective, descriptive and observational study. In patients with sus...

Androgen Deprivation Therapy for Prostate Cancer

AN D R O G E N D E P R I V A T I O N t h e r a p y ( A D T ; h e r e i n defined as medical or surgical castration) is the cornerstone treatment of advanced prostate cancer. In 1941, Huggins and Hodges first noted the beneficial effects of castration and injection of estrogens in patients with metastatic prostate cancer. The biological basis of the effect of ADT, the almost ubiquitous expressio...

Androgen deprivation therapy for prostate cancer.

CONTEXT Prostate cancer is the most common nonskin cancer and second most common cause of cancer mortality in US men. Androgen deprivation therapy (ADT), specifically surgical or medical castration, is the first line of treatment against advanced prostate cancer and is also used as an adjuvant to local treatment of high-risk disease. OBJECTIVE To review systematically the evidence on the risk...
