Brief Summary:

The purpose of this study is to try to learn more about how small molecule kinase inhibitors work in treating lung cancer. Some early studies have shown that gefitinib, erlotinib and similar drugs are more likely to work if a particular DNA change (also known as a mutation) is found in a protein that is important in lung cancer. This protein is called the epidermal growth factor receptor (EGFR). Since small molecule kinase inhibitors sometimes stop working, we would like to examine your tumor to learn why these medicines are not working as well. Your tumor will be examined for a variety of things including changes in the DNA of the EGFR. We will also sequence parts of the genes for HER2, HER3, HER4, and KRAS, other proteins thought to be important in lung cancer.

Condition or disease	Intervention/treatment
Unresectable or Metastatic Non-small Cell Lung Cancer (NSCLC)	Other: Tumor core biopsy for RNA isolation

Detailed Description:

The goal of this protocol is to determine mechanisms of resistance to epidermal growth factor (EGFR) tyrosine kinase inhibitors (EGFR-TKI) in non-small cell lung cancer (NSCLC). A number of trials have shown small molecule kinase inhibitors to be active agents in the treatment of NSCLC [1]. Clinically these drugs have been noted to produce dramatic but infrequent responses. Mutations in the epidermal growth factor receptor have been shown to correlate with sensitivity to gefitinib and erlotinib[2,3]. However, we know that most patients who have initial responses to EGFR-TKI eventually progress. The mechanism of acquired clinical resistance to these inhibitors in patients incompletely understood.

This is a protocol to study clinical characteristics and biopsy tissue of patients with non-small cell lung cancer who have had previous clinical response to small molecule kinase inhibitors and subsequently experience progression of disease. The tissues and other specimens will be used to carry out laboratory studies to explore the molecular basis of sensitivity and resistance to small molecule kinase inhibitors.

Group/Cohort	Intervention/treatment
1; This is a protocol to study tissue specimens to identify changes in tumor DNA in NSCLC patients who have previously responded to therapy and who have subsequently experienced disease progression.	Other: Tumor core biopsy for RNA isolation; RNA isolation will be carried out using approximately 25 mg of gross tissue from these tumor specimens.

Primary Outcome Measures :

1. To compare EGFR gene sequence in patients upon relapse with EGFR gene sequence prior to treatment with small molecule kinase inhibitors. [ Time Frame: 2 years ]

Secondary Outcome Measures :

1. To identify novel mutations in the tyrosine kinase domain of EGFR in patients with acquired resistance to small molecule kinase inhibitors. [ Time Frame: 2 years ]
2. To more precisely characterize the frequency and clinical implications of T790M in patients with acquired resistance to small molecule kinase inhibitors. [ Time Frame: 2 years ]
3. To identify novel mechanisms of acquired resistance to EGFR small molecule kinase inhibitors. [ Time Frame: 2 years ]

Biospecimen Retention:   Samples With DNA

Tumor biopsy material will be processed to obtain RNA for analysis of EGFR sequence. Sequencing of additional candidate genes and other studies will follow if sufficient material is available.
