Success and failure rates of tumor genotyping techniques in routine pathologic samples with non-small cell lung cancer.

8050 Background: Identification of somatic molecular alterrations in NSCLC has become evidence-based practice. The success and failure rate of using commercially-available tumor genotyping techniques in routine day-to-day NSCLC pathology samples is not well described. We sought to evaluate the success and failure rate of EGFR mutation, KRAS mutation and ALK FISH. Methods: Clinicopathologic data, tumor genotype success and failure rates were...
