BACKGROUND Sunitinib, a multitargeted tyrosine-kinase inhibitor, which is approved by both US and European Commission regulatory agencies for clinical use, extends survival of patients with metastatic renal-cell carcinoma and gastrointestinal stromal tumours, but concerns have arisen about its cardiac safety. We therefore assessed the cardiovascular risk(More)
AIMS To assess the antitumour activity, safety, pharmacokinetics and pharmacodynamics of continuous daily sunitinib dosing in patients with imatinib-resistant/intolerant gastrointestinal stromal tumour (GIST) and to assess morning dosing versus evening dosing. PATIENTS AND METHODS In this open-label phase II study, patients were randomised to receive(More)
PURPOSE Metastatic GI stromal tumor (GIST) is a life-threatening disease with no therapy of proven efficacy after failure of imatinib and sunitinib. Regorafenib is a structurally unique inhibitor of multiple cancer-associated kinases, including KIT and platelet-derived growth factor receptor (PDGFR), with broad-spectrum anticancer activity in preclinical(More)
BACKGROUND Skeletal complications are a major clinical manifestation of multiple myeloma. These complications are caused by soluble factors that stimulate osteoclasts to resorb bone. Bisphosphonates such as pamidronate inhibit osteoclastic activity and reduce bone resorption. METHODS Patients with stage III multiple myeloma and at least one lytic lesion(More)
PURPOSE While targeted inhibitors of tyrosine kinase activity demonstrate dramatic efficacy in the majority of patients with advanced gastrointestinal stromal tumors (GISTs), cure remains elusive and resistance to systemic therapy is a challenge. To assess the role of surgery in multimodality management of GISTs, we studied postoperative outcomes in(More)
BACKGROUND Sunitinib malate is an oral tyrosine kinase inhibitor recently approved for the treatment of gastrointestinal stromal tumors and renal cell carcinoma. Because the ret proto-oncogene is also inhibited by this agent, clinical evaluation of thyroid function was performed. OBJECTIVE To describe the prevalence and clinical presentation of thyroid(More)
The major changes to the 2012 and 2011 NCCN Guidelines for Soft Tissue Sarcoma pertain to the management of patients with gastrointestinal stromal tumors (GISTs) and desmoid tumors (aggressive fibromatosis). Postoperative imatinib following complete resection for primary GIST with no preoperative imatinib is now included as a category 1 recommendation for(More)
BACKGROUND Uterine leiomyosarcoma (ULMS) is identified in 0.1% to 0.2% of hysterectomy specimens of presumed leiomyoma. To date, there is no preoperative technique that reliably differentiates ULMS from uterine leiomyoma. Increasing use of minimally invasive approaches for the management of leiomyomas may result in inadvertently morcellated ULMS with(More)
PURPOSE Myxofibrosarcoma (MFS) is a rare sarcoma with a predilection for multiple local recurrences (LR), for which optimal treatment has not been defined. We reviewed our experience to determine the impact of surgery and radiation therapy (RT) on pattern of recurrence, limb salvage, and overall survival (OS). METHODS AND MATERIALS Between 1995 and 2005,(More)
PURPOSE To determine the efficacy and safety of 21 monthly cycles of pamidronate therapy in patients with advanced multiple myeloma. PATIENTS AND METHODS Patients with stage III myeloma and at least one lytic lesion received either placebo or pamidronate 90 mg intravenously administered as a 4-hour infusion monthly for 21 cycles. At study entry, the(More)
