Zoledronic Acid and Positron Emission Tomography in Treating Patients With Advanced Non-Small Cell Lung Cancer

RATIONALE: A positron emission tomography scan is a procedure in which a small amount of radioactive sugar is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where tumor cells are found. This study is looking at whether the drug zoledronic acid interferes with the ability of a PET scan to find tumor cells. PURPOSE: This phase II trial is studying how well positron emission tomography works when given together with zoledronic acid in finding tumor cells in patients with advanced non-small cell lung cancer.
