PURPOSE Circulating tumor cell (CTC) enumeration has not been prospectively validated in standard first-line docetaxel treatment for metastatic castration-resistant prostate cancer. We assessed the prognostic value of CTCs for overall survival (OS) and disease response in S0421, a phase III trial of docetaxel plus prednisone with or without atrasentan. (More)
BACKGROUND The endothelin pathway has a role in bone metastases, which are characteristic of advanced prostate cancer. Atrasentan, an endothelin receptor antagonist, has shown activity in prostate cancer. We therefore assessed its effect on survival in patients with castration-resistant prostate cancer with bone metastases. METHODS In a double-blind phase(More)
LBA4511 Background: The preclinical activity of vascular endothelial growth factor (VEGF) blockade, the inverse relationship of plasma and urine VEGF levels and survival in mCRPC patients (pts), and encouraging phase II data testing estramustine and docetaxel with bevacizumab suggested that VEGF blockade was an appropriate potential strategy in mCRPC.

Purpose Prolonged exposure of cancer cells to triapine, an inhibitor of ribonucleotide reductase, followed by gemcitabine enhances gemcitabine activity in vitro. Fixed-dose-rate gemcitabine (FDR-G) has improved efficacy compared to standard-dose. We conducted a phase I trial to determine the maximum tolerated dose (MTD), safety, pharmacokinetics (PK),(More)
BACKGROUND The treatment for prostate cancer patients with biochemical failure after local therapy remains controversial. Peripheral androgen blockade using a combination of a 5-alpha reductase inhibitor and an antiandrogen may allow control of the prostate-specific antigen (PSA). Because testosterone levels are not suppressed, this approach may be(More)
PURPOSE A randomized, placebo-controlled study based on preclinical and clinical data that supports the potential role of vascular endothelial growth factor in prostate cancer was performed to evaluate the addition of bevacizumab to standard docetaxel and prednisone therapy in patients with metastatic castration-resistant prostate cancer (mCRPC).

PURPOSE Maintaining dose-intensity with chemotherapeutic agents is hindered by a number of adverse effects including asthenia/fatigue. Tumor necrosis factor (TNF) is one of the cytokines responsible for the fatigue and cachexia associated with malignancies. We used etanercept (TNF-decoy receptor) to maintain dose-intensity of weekly docetaxel. PATIENTS(More)
Tomato and soy products are hypothesized to reduce the risk of prostate cancer or enhance efficacy of therapy. A study was completed to determine if men with active prostate cancer will adhere to a dietary intervention rich in tomato products and a soy protein supplement men (n = 41) with recurrent, asymptomatic prostate cancer were randomized among 2(More)
Radium-223 ((223)Ra) dichloride is an approved intravenous radiotherapy for patients with osseous metastases from castration-resistant prostate cancer (CRPC). In addition to the therapeutic alpha radiation, there is additional (223)Ra radiation generated which produces photons that can be imaged with conventional gamma cameras. No studies have evaluated(More)
OBJECTIVE It is hypothesized that dietary patterns, individual nutrients, and specific prescription and over-the-counter medications may influence prostate carcinogenesis. Little information is available regarding the use of these products among men who are participating in prevention trials targeting prostate cancer. MATERIALS AND METHODS A total of 92(More)
