OBJECTIVES:

• Determine the antitumor activity of gemcitabine and epirubicin in patients with malignant pleural mesothelioma.
• Determine the toxicity of this regimen in this patient population.
• Determine the time to progression and overall survival of patients treated with this regimen.
• Assess quality of life in patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive gemcitabine IV over 30 minutes on days 1 and 8 and epirubicin IV on day 1. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients achieving complete response (CR) receive 2 additional courses beyond CR.

Quality of life is assessed at baseline, prior to course 3, at 3 months, and then at 1 year.

Patients are followed every 3 months for 1 year, every 4 months for 1 year, and then every 6 months for 3 years.

PROJECTED ACCRUAL: A total of 15-41 patients will be accrued for this study within 6-18 months.
