Objective: To evaluate the efficacy and toxicity of the association of mitoxantrone and oral etoposide. Methods: Twelve consecutive patients with metastatic hormone-refractory prostate cancer were treated with mitoxantrone and oral etoposide. Toxicity, response rate and response duration were assessed. results: Partial response was observed in two patients (response duration of seven and four m...

Prostate cancer is the second most common cancer in men in the UK, and the incidence of prostate cancer has increased dramatically over the past two decades. Although most men are diagnosed at early stage, more than 50% develop locally advanced or metastatic disease. Androgen ablation with luteinising hormone-releasing hormone (LHRH) agonists alone, or in combination with anti-androgens, is the...

Cancers of the prostate are categorized as follows: 1)hormone-naive (never having previously received hormone manipulation); 2)androgen-dependent (having received hormonal manipulation but a less than continuous application, i.e., intermittent androgen blockade or with an agent that does not produce a castrate testosterone level, i.e., antiandrogen); 3)androgen independent (progressive disease ...

Prostate cancer ranks as the most common lethal malignancy diagnosed and the second leading cause of cancer mortality in American men. Although high response rates are achieved using androgen blockade as first-line therapy, most men progress toward hormone-refractory prostate cancer. Systemic chemotherapies have been shown to improve clinical outcome in hormone refractory prostate cancer patien...

Androgen receptor plays a critical role in the development of primary as well as advanced hormone-refractory prostate cancer. Therefore, ablation of androgen receptor from prostate cancer cells is an interesting concept for developing a new therapy not only for androgen-dependent prostate cancer but also for metastatic hormone-refractory prostate cancer, for which there is no effective treatmen...

Prostate cancer is the second leading cause of cancer death in men in the United States. Novel immunotherapies are being investigated to improve survival in patients with advanced disease. Sipuleucel-T (PROVENGE), the first autologous cellular immunotherapy approved by the U. S. Food and Drug Administration, improves survival in men with asymptomatic or minimally symptomatic metastatic castrati...

PURPOSE Patients in whom prostate cancer progresses despite testicular androgen ablation are generally said to have cancers that have become resistant to hormonal maneuvers. If androgen suppression has been pharmacologic, this therapy is often stopped before consideration of other systemic treatments. This exploratory study sought clinical correlates of experimental evidence that there may be s...

Castration-resistance prostate cancer (CRPC), also known as hormone-refractory prostate cancer (HRPC), requires immediate attention since it is not only resistant to androgen ablation, chemo- and radiotherapy, but also highly metastatic. Increasing evidence suggests that enrichment of neuroendocrine (NE) cells is associated with CRPC. Here, combined RNA-seq and ChIP-seq analysis reveals that RE...

Hormone-refractory prostate cancer shows substantial resistance to most conventional therapies including radiotherapy, constitutes a key impediment to curing patients with the disease. c-Met overexpression plays a key role in prostate cancer tumorigenesis and disease progression. Here, we demonstrate that c-Met inhibition by SU11274 could significantly suppress cell survival and proliferation a...
