capecitabine in treating patients with malignant mesothelioma

Conditions: Malignant Mesothelioma

Summary: rationale: drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. purpose: phase ii trial to study the effectiveness of capecitabine in treating patients who have malignant mesothelioma.

objectives: i. determine the response rate, overall survival, and failure free survival of patients with malignant mesothelioma treated with capecitabine. ii. determine the toxicity of this regimen in these patients. outline: this is a multicenter study. patients receive oral capecitabine twice daily on days 1-14. treatment repeats every 3 weeks for a maximum of 6 courses in the absence of disease progression or unacceptable toxicity. patients are followed every 2 months for 1 year, every 3 months for 2 years and then annually thereafter. projected accrual: a total of 25 patients will be accrued for this study within 7-9 months.
