Aggressive androgen-independent (also termed as hormone-refractory) prostate cancer is a major clinical obstacle because there is no means to cure. Previous studies have shown that Akt activation is associated with prostate cancer progression from androgen-dependent to androgen-independent stage. However, its causative role in this process has not been established. One of the major limitations ...

Prognostic factors in hormone refractory prostate cancer currently are of limited use to clinicians. Although studies have identified several factors that predict for poor survival in patients, most are either retrospective, or nonrandomized. Therefore, large prospective, randomized trials are needed to validate the significance of these factors. In addition, these indicators are largely descri...

Over 60 years ago, Huggins and Hodges discovered androgen deprivation as an effective first-line therapy for metastatic prostate cancer. This leads to significant cancer control but in almost all men prostate cancer ultimately progresses to a hormone-refractory (HRPC) state resulting in significant morbidity and eventual death. In 2004, two landmark studies using docetaxel based chemotherapy de...

Prostate cancer development and progression is driven by the accumulation of genetic changes, the nature of which remains incompletely understood To facilitate high-throughput analysis of molecular events taking place in primary, recurrent, and metastat prostate cancer, we constructed a tissue microarray containing small 0.6-mm cylindrical samples acquired from 371 formalin-fixed blocks, includ...

Recent experimental observations, showing the potential role of prolactin (PRL) as a tumor growth factor for prostate cancer and the unfavourable prognostic significance of enhanced chromogranin-A-secreting neuroendocrine cell proliferation, could contribute to a better understanding of the mechanisms responsible for the occurrence of hormone-resistance in the prostate cancer. Moreover, it has ...

As new evidence for prostate cancer treatment has emerged in the last few years, longstanding controversies in the treatment of prostate cancer have resurfaced. A number of long-held tenets of prostate cancer therapy have been revisited, sometimes with surprising and challenging results. Although neoadjuvant hormonal therapy prior to radical prostatectomy decreases positive surgical margin rate...

OBJECTIVE To evaluate the role of Estrogens (Honvan) in the secondary hormonal manipulation of patients with hormone refractory prostate cancer (HRCP). METHODS Twelve patients diagnosed as hormone refractory prostate cancer received intravenous estrogens for six days (Fosfestrol, a synthetic phosphorylated estrogen derivative), followed by a maintenance oral dose of 120 mg thrice daily as sec...

In this review, we describe how clinical investigators addressed some of the challenges in prostate cancer chemotherapy trials 20 years ago, and we indicate what has evolved in the field since that time. We consider the impact that prostate-specific antigen measurement had in this setting, evolving clinical paradigms, multidisciplinary programs, and the current armamentarium of cancer treatment...
