Abstract: The present invention is directed to a method for determining the responsiveness of cancer to an epidermal growth factor receptor (EGFR) treatment. In a preferred embodiment, the presence of at least one variance in the kinase domain of the erbB1 gene confers sensitivity to the tyrosine kinase inhibitor gefitinib. Thus, a diagnostic assay for these mutations will allow for the administration of gefitinib, erlotinib and other tyrosine kinase inhibitors to those patients most likely to respond to the drug.

Abstract: The invention provides a molecular taxonomy of lung carcinoma, the leading cause of cancer death in the United States and worldwide. Oligonucleotide microarrays were used to analyze mRNA expression levels corresponding to 12,600 transcript sequences in 186 lung tumor samples, including 139 adenocarcinomas resected from the lung. Hierarchical and probabilistic clustering of expression data defined distinct subclasses of lung adenocarcinoma. Among these were tumors with high relative expression of neuroendocrine genes and of type II pneumocyte genes, respectively. Retrospective analysis revealed a less favorable outcome for the adenocarcinomas with neuroendocrine gene expression. The diagnostic potential of expression profiling is emphasized by its ability to discriminate primary lung adenocarcinomas from metastases of extrapulmonary origin. These results suggest that integration of expression profile data with clinical parameters could aid in diagnosis of lung cancer patients.
