Chemotherapy Plus Radiation Therapy With or Without Surgery in Treating Patients With Stage IIIA Non-small Cell Lung Cancer

• Status: Completed
• Trial end date: 2013-11-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining radiation therapy with chemotherapy may kill more tumor cells. It is not yet known if chemotherapy plus radiation therapy is more effective with or without surgery for lung cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of combining cisplatin, etoposide, and radiation therapy with or without surgery in treating patients who have stage IIIA non-small cell lung cancer.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Radiation Therapy Oncology Group
• Collaborators: Cancer and Leukemia Group B; Eastern Cooperative Oncology Group; National Cancer Institute (NCI); NCIC Clinical Trials Group; North Central Cancer Treatment Group; Southwest Oncology Group
• Treatments: Etoposide

Criteria

DISEASE CHARACTERISTICS:

• Histologically or cytologically proven newly diagnosed, stage IIIA (T1-3, N2) non-small cell lung cancer

• Eligible subtypes:

• Adenocarcinoma

• Large cell carcinoma

• Squamous cell carcinoma

• Nonlobar and nondiffuse bronchoalveolar cell carcinoma

• Measurable or evaluable disease on chest x-ray and/or contrast CT scan

• Contrast thoracic CT required to complete staging

• Single primary bronchogenic tumor (no more than 1 parenchymal lung lesion)

• Pleural effusions allowed if 1 of the following conditions is met:

• Negative cytology on thoracentesis if effusions present before mediastinoscopy or exploratory thoracotomy

• Effusion seen on CT scan but not on chest x-ray and deemed too small to tap under CT or ultrasound guidance

• Positive ipsilateral mediastinal node(s) with or without positive ipsilateral hilar nodes

• Mediastinal nodes separate from primary lesion on CT scan or surgical exploration

• Histologic or cytologic proof of N2 disease by thoracotomy, mediastinoscopy, mediastinotomy, Chamberlain procedure, Wang needle, or fine needle aspiration under bronchoscopic or CT guidance

• Nodal biopsy or aspiration waived if all of the following conditions are met:

• Paralyzed left true vocal cord documented by bronchoscopy or indirect laryngoscopy

• Nodes visible in Level 5 region on CT scan

• Distinct primary lesion separate from nodes on CT scan

• All mediastinal nodal involvement mapped (positive or negative)

• No positive nodes in contralateral mediastinum (supraclavicular areas and higher) and neck

• Mediastinoscopy, mediastinotomy, Chamberlain procedure, or thoracotomy required for nodes larger than 1 cm on contrast CT scan

• Surgery waived if nodes negative or no larger than 1 cm on CT scan

• Lymphadenopathy allowed if biopsy proof of a benign cause

• No metastases by contrast CT or MRI scan of the brain, bone scan, CT scan of the lungs to exclude other ipsilateral or contralateral parenchymal lesions, and contrast CT scan of the upper abdomen including entire liver and adrenals

• No hepatomegaly or splenomegaly by physical examination or CT scan unless documentation of a benign cause

• No pericardial effusion

• No superior vena cava syndrome

• No prior diagnosis of lung cancer
