18F-Fluciclovine PET metabolic imaging reveals prostate cancer tumour heterogeneity associated with disease resistance to androgen deprivation therapy

Heterogeneity in high-risk prostate cancer treated with high-dose radiation therapy and androgen deprivation therapy

BACKGROUND Our aim was to assess the heterogeneity of high-risk (HR) prostate cancer managed with high-dose external beam radiotherapy (EBRT) with androgen deprivation therapy (ADT). METHODS We identified 547 patients who were treated with modern EBRT from 1997 to 2013, of whom 98% received ADT. We analyzed biochemical relapse-free survival (bRFS) and distant metastases-free survival (DMFS). ...

Androgen Deprivation Therapy for Prostate Cancer

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...

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...
