PURPOSE To investigate the benefit of chemotherapy in patients with symptomatic hormone-resistant prostate cancer using relevant end points of palliation in a randomized controlled trial. PATIENTS AND METHODS We randomized 161 hormone-refractory patients with pain to receive mitoxantrone plus prednisone or prednisone alone (10 mg daily). Nonresponding(More)
BACKGROUND The benefit of cytoreductive nephrectomy (CN) for overall survival (OS) is unclear in patients with synchronous metastatic renal cell carcinoma (mRCC) in the era of targeted therapy. OBJECTIVE To determine OS benefit of CN compared with no CN in mRCC patients treated with targeted therapies. DESIGN, SETTING, AND PARTICIPANTS Retrospective(More)
OBJECTIVES To determine in a prospective pilot study the safety and efficacy of cryosurgical ablation for localized prostate carcinoma. METHODS A total of 87 cryosurgical procedures were performed on 76 consecutive patients between December 1994 and February 1998. All patients had histologically proved adenocarcinoma of the prostate, with(More)
PURPOSE To compare the incidence of palliative response in patients with hormone-resistant prostate cancer (HRPC) treated with mitoxantrone and prednisone (MP) plus clodronate with that of patients treated with MP plus placebo. MATERIALS AND METHODS Men with HRPC, bone metastases, and bone pain were randomly assigned to receive clodronate 1,500 mg(More)
PURPOSE To evaluate the efficacy and toxicity of gemcitabine (2',2'-difluorodeoxycytidine) in previously untreated patients with advanced transitional cell carcinoma. PATIENTS AND METHODS Forty-one patients with measurable advanced transitional cell carcinoma who had received no prior chemotherapy for metastatic disease were scheduled to receive(More)
The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has markedly increased over the last three decades due to newly found associations with human papillomavirus (HPV) infection. Primary radiotherapy (RT) is the treatment of choice for OPSCC at most centers, and over the last decade, the addition of concurrent chemotherapy has led to a significant(More)
Despite improvements in treatment of localized prostate cancer, local recurrence remains a significant problem. A total of 46 patients with proven local cancer recurrence following external beam radiotherapy entered a prospective clinical trial using ultrasound-guided cryosurgery to ablate the residual prostate gland. Persistent complications included one(More)
PURPOSE Overexpression of the epidermal growth factor receptor has been demonstrated in advanced prostate cancer and is associated with a poor outcome. A multi-institutional, randomized, phase II study was undertaken by the National Cancer Institute of Canada-Clinical Trials Group to evaluate the efficacy and toxicity of two doses of oral gefitinib in(More)
Swedish adjustable gastric banding (SAGB) is a widespread laparoscopic procedure in bariatric surgery. Few long-term data is available. To determine long-term outcome after SAGB in 196 patients studied prospectively. 196 patients, 40 men, and 156 women have been operated from 1996 to 2005. Age was 38 ± 1 (mean ± sem) years. Mean follow-up was 63 ± 2 months.(More)
BACKGROUND The Hedgehog pathway inhibitor vismodegib has shown clinical benefit in patients with advanced basal cell carcinoma and is approved for treatment of patients with advanced basal cell carcinoma for whom surgery is inappropriate. STEVIE was designed to assess the safety of vismodegib in a situation similar to routine practice, with a long(More)
