PURPOSE This study was undertaken to determine the safety, dose-limiting toxicities (DLT), maximum-tolerated dose (MTD), and pharmacokinetics of imatinib in cancer patients with renal impairment and to develop dosing guidelines for imatinib in such patients. PATIENTS AND METHODS Sixty adult patients with advanced solid tumors and varying renal function(More)
Purpose Cytotoxic and anti-angiogenic drugs are efficacious in malignancies. This trial was undertaken to evaluate the toxicity of a novel regimen combining docetaxel and lenalidomide. Patients and methods Patients with advanced solid tumors were eligible. Docetaxel was administered on day 1, and lenalidomide was given on days 1–14 of each 21-day cycle.(More)
Gastrointestinal stromal tumors (GISTs) are the most common sarcoma of the alimentary tract and are believed to derive from the interstitial Cell of Cajal. Imatinib mesylate (Gleevec; Novartis, Basel, Switzerland) has revolutionized the treatment of GISTs and is generally used in the metastatic and adjuvant settings. We report the case of a 61-year old man(More)
Metastatic colorectal cancer is very common in the Western hemisphere and current treatment modalities are not effective. In this study a prolonged (150-minute) infusion of gemcitabine at a constant dose rate of 10 mg/m2/min administered weekly for 3 consecutive weeks repeated every 4 weeks revealed a response rate of 4% (90% CI < 1%–18%). There were no(More)
Combining cytotoxic agents with bevacizumab has yielded significant benefits in a number of solid tumors. Combining small-molecule kinase inhibitors of VEGFR with chemotherapy has yet to demonstrate clinical benefit. The dose, schedule and agents used may be critical to the development of this combinatorial therapy. We performed a phase I trial of sunitinib(More)
OBJECTIVES To analyze the impact of surgical margins and other clinicopathological data on treatment outcomes on 75 patients treated from 1999 to 2006 by initial potentially curative surgery (+/- intraoperative radiotherapy), followed by high-dose 3-dimensional conformal radiation therapy and concomitant fluoropyrimidine-based chemoradiotherapy. MATERIALS(More)
Purpose: Pre-clinical models have demonstrated the benefit of metronomic schedules of cytotoxic chemotherapy combined with anti-angiogenic compounds. This trial was undertaken to determine the toxicity of a low dose regimen using docetaxel and thalidomide. Patients and Methods: Patients with advanced solid tumors were enrolled. Thalidomide 100mg twice daily(More)
BACKGROUND Src, EphA2, and platelet-derived growth factor receptors α and β are dysregulated in pancreatic ductal adenocarcinoma (PDAC). METHODS Dasatinib is an oral multitarget tyrosine kinase inhibitor that targets BCR-ABL, c-Src, c-KIT, platelet-derived growth factor receptor β, and EphA2. We conducted a phase II, single-arm study of dasatinib as(More)
To determine the safety, the maximal tolerated dose, and to assess for any clinical activity of pomalidomide given to patients with advanced solid tumors. Patients with incurable solid tumors were enrolled. Two different dosing schedules were explored. In Cohort A patients were given pomalidomide once daily for 21 days followed by a 7 day rest. For Cohort B(More)
