简要总结
Phase II trial to study the effectiveness of gefitinib in treating patients who have malignant mesothelioma. Biological therapies such as gefitinib may interfere with the growth of the tumor cells and slow the growth of malignant mesothelioma
详细描述
OBJECTIVES:
I. Determine the activity of gefitinib, in terms of failure-free survival, in patients with malignant mesothelioma.
II. Determine the response rate in patients treated with this drug. III. Determine the toxicity of this drug in these patients. IV. Determine the overall survival of patients treated with this drug. V. Determine whether overexpression of epidermal growth factor receptor and expression of cyclo-oxygenase-2 can predict the effectiveness of this drug in these patients.
OUTLINE: This is a multicenter study.
Patients receive oral gefitinib once daily on days 1-21. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity.
