RATIONALE: Drugs used in chemotherapy, such as gemcitabine, carboplatin, and paclitaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with chemotherapy may kill more tumor cells.
- Determine the maximum tolerated dose (MTD) of gemcitabine when administered with carboplatin and thoracic radiotherapy followed by adjuvant gemcitabine and carboplatin in patients with stage IIIA or IIIB non-small cell lung cancer.
- Determine the MTD of gemcitabine and paclitaxel when administered with thoracic radiotherapy followed by adjuvant gemcitabine and carboplatin in these patients.
OUTLINE: This is a multicenter, dose-escalation study of gemcitabine and paclitaxel. Patients are sequentially assigned to 1 of 3 treatment regimens.
- Regimen A: Patients receive gemcitabine IV over 30-60 minutes on days 1, 8, 22, 29, and 43 and thoracic radiotherapy daily 5 days a week for 7 weeks beginning on day 1.
- Regimen B (closed to accrual as of 5/13/03): Patients receive gemcitabine and thoracic radiotherapy as in regimen A and carboplatin IV over 30 minutes on days 1, 8, 22, 29, and 43.
- Regimen C: Patients receive gemcitabine and thoracic radiotherapy as in regimen A and paclitaxel IV over 1 hour on days 1, 8, 22, 29, and 43.
At 3 weeks after completion of chemoradiotherapy, all patients receive adjuvant gemcitabine IV over 30-60 minutes on days 71, 78, 92, and 99 and carboplatin IV over 30 minutes on days 71 and 92.
The first 6 patients enrolled receive regimen A to determine the safety of the initial dose of gemcitabine. After completion of regimen A, cohorts of 3-6 patients receive escalating doses of gemcitabine in regimen B (closed to accrual as of 5/13/03) until the maximum tolerated dose (MTD) is determined. In a separate sequence, cohorts of 3-6 patients receive alternating escalating doses of gemcitabine and paclitaxel in regimen C until the MTD is determined. The MTD is defined as the dose preceding that at which at least 3 of 6 patients experience dose-limiting toxicity.
Patients are followed at 3 months, 6 months, every 3 months for 1 year, every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A maximum of 78 patients will be accrued for this study within 29 months.

Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
A therapeutic approach, involving chemotherapy, radiation therapy, or surgery, after initial regimens have failed to lead to improvement in a patient's condition. Salvage therapy is most often used for neoplastic diseases.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
Radiotherapy given to augment some other form of treatment such as surgery or chemotherapy. Adjuvant radiotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
