PURPOSE To determine the dose-limiting toxicity and maximum-tolerated dose of the proteasome inhibitor bortezomib administered intravenously weekly for 4 every 5 weeks; to determine the bortezomib pharmacokinetics and pharmacodynamics using plasma levels and an assay for 20S proteasome inhibition (PI) in whole blood; to correlate toxicity with bortezomib(More)
BACKGROUND Prostate carcinoma is linked to osteoblastic metastasis. We therefore investigated the value of bone-targeted consolidation therapy in selected patients with advanced androgen-independent carcinoma of the prostate. METHODS 103 patients received induction chemotherapy, consisting of ketoconazole and doxorubicin alternating with estramustine and(More)
BACKGROUND The current study was conducted to report the severity and management of canalicular and nasolacrimal duct stenosis as a side effect of docetaxel therapy and to report the outcomes of surgical intervention for this condition. METHODS The records of 148 patients with epiphora associated with docetaxel therapy who were evaluated at the(More)
PURPOSE To further assess preclinical and early clinical evidence that imatinib mesylate, a platelet-derived growth factor receptor (PDGFR) inhibitor, modulates taxane activity in prostate cancer and bone metastases, a randomized study was conducted. EXPERIMENTAL DESIGN Men with progressive castration-resistant prostate cancer with bone metastases (n =(More)
PURPOSE Clinical features characteristic of small-cell prostate carcinoma (SCPC), "anaplastic," often emerge during the progression of prostate cancer. We sought to determine the efficacy of platinum-based chemotherapy in patients meeting at least one of seven prospectively defined "anaplastic" clinical criteria, including exclusive visceral or(More)
OBJECTIVES There are limited studies characterizing cancer-related symptoms in outpatient advanced prostate cancer patients. The aim of this retrospective study was to describe the impact of an outpatient palliative care (PC) consultation on symptoms in patients with advanced prostate cancer. METHODS We retrospectively reviewed the medical records of 55(More)
PURPOSE We investigated the feasibility, safety, and antitumor activity of weekly gemcitabine given in combination with low doses of cisplatin and ifosfamide in previously treated patients with advanced transitional-cell carcinoma (TCC) of the urothelium. PATIENTS AND METHODS Patients with measurable, metastatic or unresectable TCC who had received one or(More)
BACKGROUND Skeletal metastases from renal cell carcinoma are highly destructive vascular lesions. They pose unique surgical challenges due to the risk of life-threatening hemorrhage and resistance to other treatments. The goal of this retrospective study was to evaluate factors that may affect survival after surgical treatment of metastases of renal cell(More)
An explanation for the inherently metastatic and heterogeneous nature of cancers may be their derivation from distinct stem cells. The type of stem cell from which a neoplasm arises determines both the metastatic potential and the phenotypic diversity of that neoplasm. Hence, tumours originating from an early stem cell or its progenitor cells metastasise(More)
Stem cells have long been implicated in prostate gland formation. The prostate undergoes regression after androgen deprivation and regeneration after testosterone replacement. Regenerative studies suggest that these cells are found in the proximal ducts and basal layer of the prostate. Many characteristics of prostate cancer indicate that it originates from(More)
