BACKGROUND Pazopanib, a multitargeted tyrosine kinase inhibitor, has single-agent activity in patients with advanced non-adipocytic soft-tissue sarcoma. We investigated the effect of pazopanib on progression-free survival in patients with metastatic non-adipocytic soft-tissue sarcoma after failure of standard chemotherapy. METHODS This phase 3 study was(More)
BACKGROUND Until now, only imatinib and sunitinib have proven clinical benefit in patients with gastrointestinal stromal tumours (GIST), but almost all metastatic GIST eventually develop resistance to these agents, resulting in fatal disease progression. We aimed to assess efficacy and safety of regorafenib in patients with metastatic or unresectable GIST(More)
Cancer immunosurveillance relies on effector/memory tumor-infiltrating CD8(+) T cells with a T-helper cell 1 (TH1) profile. Evidence for a natural killer (NK) cell-based control of human malignancies is still largely missing. The KIT tyrosine kinase inhibitor imatinib mesylate markedly prolongs the survival of patients with gastrointestinal stromal tumors(More)
PURPOSE This study explored factors affecting the pharmacokinetic variability of imatinib and CGP 74588, and the pharmacokinetic-pharmacodynamic correlations in patients with advanced gastrointestinal stromal tumors. EXPERIMENTAL DESIGN Thirty-five patients with advanced gastrointestinal stromal tumors received 400 mg of imatinib daily. Six blood samples(More)
BACKGROUND A non-randomised, phase 2 study showed activity and tolerability of eribulin in advanced or metastatic soft-tissue sarcoma. In this phase 3 study, we aimed to compare overall survival in patients with advanced or metastatic soft-tissue sarcoma who received eribulin with that in patients who received dacarbazine (an active control). METHODS We(More)
Aggressive fibromatosis (AF) is a monoclonal proliferative disease but does not metastasize and does not dedifferentiate to a high-grade malignancy in case of recurrence. Biopsy is usually necessary to confirm the diagnosis. A hallmark is its apparent unpredictable clinical course producing a large heterogeneity even with an indistinguishable morphology.(More)
BACKGROUND Imatinib evaluated as a new treatment option in patients with recurrent or established progressive aggressive fibromatosis/desmoid tumor (AF/DT). PATIENTS AND METHODS Forty patients with unresectable and progressive symptomatic AF/DT were treated with imatinib (400 mg/day for 1 year) in a Simon's optimal two-stage phase II study (P(0) = 10%,(More)
BACKGROUND Angiosarcomas are rare, heterogeneous and a retrospective study was conducted to describe their natural history. PATIENTS AND METHODS We reviewed 161 files of angiosarcoma treated in three institutions of the French Sarcoma Group from 1980 to 2004. Survival and prognostic factors for survival were analyzed. RESULTS Median age was 52 years.(More)
BACKGROUND Clear cell sarcoma, or malignant melanoma of soft parts, is a rare tumor that occurs predominantly in the extremities of young adults. The importance of surgery has been well established. However, the role of adjuvant radiotherapy has yet to be determined. METHODS Thirty cases of clear cell sarcoma that occurred in The Netherlands between 1978(More)
PURPOSE To determine the dose of trabectedin plus doxorubicin with granulocyte colony-stimulating factor support associated with manageable neutropenia and acceptable dose-limiting toxicities (DLT) in patients with recurrent or persistent soft-tissue sarcoma. METHODS In this phase I, open-label, multicenter trial, patients previously treated with 0-1(More)
