Brief summary: RATIONALE: Pemetrexed disodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving pemetrexed disodium together with gemcitabine may kill more tumor cells.

PURPOSE: This randomized phase II trial is studying two different schedules of pemetrexed disodium and gemcitabine to compare how well they work in treating patients with stage IIIB or stage IV non-small cell lung cancer.

Detailed description: OBJECTIVES:

Primary

* Compare response rates in patients with stage IIIB or IV non-small cell lung cancer treated with two different treatment schedules of pemetrexed disodium and gemcitabine hydrochloride.

Secondary

* Compare time-to-event efficacy variables in patients treated with these regimens.
* Compare progression-free and overall survival of patients treated with these regimens.
* Determine the overall toxicity of these regimens in these patients.

OUTLINE: This is a multicenter, open-label, randomized study. Patients are stratified according to disease stage (IIIB vs IV) and ECOG performance status (0 vs 1). Patients are randomized to 1 of 2 treatment arms.

* Arm I: Patients receive pemetrexed disodium IV over 10 minutes and gemcitabine hydrochloride IV over 30 minutes on days 1 and 8. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
* Arm II: Patients receive pemetrexed disodium IV over 10 minutes and gemcitabine hydrochloride IV over 30 minutes on day 1. Treatment repeats every 14 days for up to 9 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically for up to 2 years.

PROJECTED ACCRUAL: A total of 80 patients will be accrued for this study.
