About

RATIONALE: Drugs used in chemotherapy, such as pemetrexed disodium and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Pemetrexed disodium may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving combination chemotherapy before surgery may shrink the tumor so that it can be removed. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This phase II trial is studying how well giving pemetrexed disodium and cisplatin followed by surgery and radiation therapy works in treating patients with malignant pleural mesothelioma.

Full description

OBJECTIVES:

Primary

• Determine the feasibility of neoadjuvant chemotherapy comprising pemetrexed disodium and cisplatin followed by extrapleural pneumonectomy and high-dose postoperative 3D-conformal radiotherapy, in terms of 90-day progression-free survival, in patients with malignant pleural mesothelioma.

Secondary

• Determine the toxicity of this regimen in these patients.
• Determine progression-free survival and overall survival of patients treated with this regimen.

OUTLINE: This is a non-randomized, multicenter study.

• Neoadjuvant chemotherapy: Patients receive pemetrexed disodium IV over 10 minutes and cisplatin IV over 2 hours on day 1. Treatment repeats every 3 weeks for up to 3 courses in the absence of disease progression or unacceptable toxicity. Patients are evaluated 3 weeks after completion of neoadjuvant chemotherapy. Patients without disease progression proceed to surgery.
• Extrapleural pneumonectomy: Within 21-56 days after completion of neoadjuvant chemotherapy, patients undergo extrapleural pneumonectomy. Patients are evaluated 30 days after surgery. Patients without disease progression undergo high-dose 3D-conformal radiotherapy.
• High-dose 3D-conformal radiotherapy: Beginning 30-84 days after surgery, patients undergo high-dose 3D-conformal radiotherapy daily for 30 days.

After completion of study treatment, patients are followed on days 42 and 90, every 3 months for 1 year, and then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 52 patients will be accrued for this study.

Enrollment: 59 patients
