Combination Chemotherapy Plus Radiation Therapy in Treating Patients With Stage III Non-small Cell Lung Cancer

DISEASE CHARACTERISTICS: Histologically or cytologically confirmed non-small cell lung cancer (NSCLC) Stage IIIA (T1-2, N2, M0 or T3, N1-2, M0) if not medically operable Stage IIIB (any T, N3, M0 or T4, any N, M0) Radiographic evidence of mediastinal lymph nodes at least 2.0 cm in the largest diameter sufficient to stage N2 or N3 disease If largest mediastinal node is less than 2.0 cm in diameter and is the basis for stage III disease, then at least one node must be histologically or cytologically confirmed positive Any of the following histologies allowed: Squamous cell carcinoma Adenocarcinoma (including bronchoalveolar cell) Large cell anaplastic carcinoma (including giant and clear cell carcinomas) Poorly differentiated NSCLC No metastatic disease Patients with tumors adjacent to a vertebral body allowed if all gross disease can be encompassed in the radiation boost field (boost volume must be limited to less than 50% of the ipsilateral lung volume) Pleural effusions that are a transudate, cytologically negative, and non-bloody are allowed if tumor can be encompassed within reasonable field of radiotherapy Pleural effusions that can be seen on chest CT but not on chest x-ray and are too small to tap are allowed No brain metastases by MRI or CT scan No prior total surgical resection PATIENT CHARACTERISTICS: Age: 18 and over Performance status: Karnofsky 70-100% Life expectancy: Not specified Hematopoietic: Granulocyte count at least 2,000/mm3 Platelet count at least 100,000/mm3 Hemoglobin greater than 8 g/dL (transfusion or epoetin alfa allowed) Hepatic: Bilirubin less than 1.5 times normal Renal: Creatinine clearance greater than 50 mL/min Cardiovascular: No history of uncontrolled serious cardiac disease No myocardial infarction within the past 6 months No congestive heart failure No unstable angina No clinically significant pericardial effusion or arrhythmia Pulmonary: FEV1 greater than 800 mL Post obstructive pneumonia allowed Other: No other active concurrent or prior malignancy within the past 5 years except nonmelanomatous skin cancer or carcinoma in situ of the cervix No other serious medical or psychiatric illness that would preclude study No active serious infection No prior significant allergic reactions to drugs containing Cremophor (e.g., cyclosporine or vitamin K) No weight loss of more than 10% within 3 months prior to diagnosis Not pregnant or nursing Negative pregnancy test Fertile patients must use effective contraception PRIOR CONCURRENT THERAPY: Biologic therapy: No concurrent colony stimulating factors (i.e., filgrastim (G-CSF) or sargramostim (GM-CSF)) No concurrent immunotherapy Concurrent epoetin alfa allowed Chemotherapy: No prior systemic chemotherapy No other concurrent chemotherapy Endocrine therapy: No concurrent hormonal agents except for nondisease related conditions (e.g., insulin for diabetes) Concurrent steroids administered for adrenal failure or septic shock allowed Concurrent glucocorticosteroids as antiemetics allowed Radiotherapy: No prior radiotherapy to the thorax Surgery: See Disease Characteristics At least 3 weeks since formal exploratory thoracotomy and recovered At least 1 week since prior diagnostic thoracoscopy Other: No other concurrent anticancer drugs
