Unresectable or Metastatic Non-small Cell Lung Cancer (NSCLC) | Other: Tumor core biopsy for RNA isolation |
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.

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. |
- 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 ]
- 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 ]
- 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 ]
- To identify novel mechanisms of acquired resistance to EGFR small molecule kinase inhibitors. [ Time Frame: 2 years ]
