Primary outcomePrimary: Change in Tumor SUVmax Assessed by 18F-FLT PET Imaging — -0.39 SUVmax — p=0.087
Summary
This pilot research trial studies the effects of dexamethasone in patients with non-small cell lung cancer that has not responded after previous treatment. Drugs such as dexamethasone can affect how tumors grow and respond to treatments. Imaging tests, such as fluoro-L-thymidine (FLT) positron emission tomography , use a small amount of radioactive substance to show changes in tumor cells. Studying the effects of dexamethasone on lung tumors using FLT positron emission tomography may help doctors plan better treatments.

Eligibility Criteria
Inclusion Criteria
- Patients must have histologically or cytologically proven advanced non-squamous NSCLC. Patients may have newly diagnosed recurrent progressive or refractory disease which may be localized or wide spread.
- No chemotherapy for at least 4 weeks and no radiation to the index lesion or clear progression in that lesion (greater than 20% increase in longest diameter).
- Life expectancy of greater than 4 weeks
- Absolute neutrophil count >= 1, 000/mcL (measured within 2 weeks of registration)
- No history of human immunodeficiency virus (HIV) or active infections
- No history of diabetes
- No surgery in the last 2 weeks prior to study enrollment
- Has not received Dex or another corticosteroid in over 4 weeks prior to enrollment
- Ability to understand and the willingness to sign a written informed consent document
- Agreed to FLT-PET imaging and signed consent and eligible FLT-PET protocol 2006-127
- Registered with the clinical trials office of the Karmanos Cancer Center/Wayne State University
Exclusion Criteria
- Patients must have measureable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 20 mm with conventional techniques (computed tomography [CT], magnetic resonance [MR] or PET); lesions in the previously irradiated area can be considered as measureable lesions as long as there has been an increase of at least 10 mm when compared to measurements obtained after completion of radiation
