About

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving a chemotherapy drug before surgery may shrink the tumor so that it can be removed during surgery. Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known whether chemotherapy followed by surgery with or without radiation therapy is more effective than chemotherapy followed by radiation therapy alone in treating non-small cell lung cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy followed by surgery with or without radiation therapy to that of chemotherapy followed by radiation therapy alone in treating patients who have stage III non-small cell lung cancer.

Full description

OBJECTIVES:

• Compare the overall survival of patients with stage IIIA non-small cell lung cancer treated with surgery with or without radiotherapy versus radiotherapy alone after achieving a response to a neoadjuvant chemotherapy regimen containing cisplatin or carboplatin.
• Compare the progression-free survival of patients treated with these regimens.
• Compare the toxic effects of these regimens in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to participating center, response to induction chemotherapy (complete vs partial vs minor), and histological subtype (squamous vs nonsquamous).

All patients receive 3 courses of induction combination chemotherapy comprising cisplatin or carboplatin in the absence of disease progression or unacceptable toxicity. Patients with complete or partial response (or minor response if disease has become resectable) are randomized to 1 of 2 treatment arms.

• Arm I: Within 6 weeks of randomization, patients undergo radical lobectomy or pneumonectomy plus dissection of the hilar and mediastinal lymph nodes.

Patients with positive resection margins of at least 1 cm and/or positive mediastinal nodes undergo radiotherapy 5 days a week for 5.5 weeks.

Patients with postresection subclinical/microscopic disease with negative tumor margins undergo radiotherapy 5 days a week for 4-4.5 weeks.

• Arm II: Within 6 weeks of randomization, patients undergo primary radiotherapy. Patients with subclinical/microscopic disease with negative tumor margins undergo radiotherapy 5 days a week for 4-4.5 weeks.

Patients with gross tumor volume and tumor margins at least 1 cm undergo radiotherapy 5 days a week for 6 weeks.

Patients are followed every 3 months for 2 years and then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 640 patients will be accrued for this study within 8 years.
