EGFR gene amplification has been reported in a subset of colorectal adenocarcinomas, lung non-small cell carcinomas, and glioblastoma multiforme. Amplification the EGFR gene can often result in overexpression of epidermal growth factor and may contribute to tumorigenesis. With the availability of anti-EGFR monoclonal antibody therapy and small molecular EGFR inhibitors, assessment of EGFR gene amplification may be warranted in some tumors to predict those that may respond to anti-EGFR therapy. This FISH assay uses the established method described by Capuzzo et al., to evaluate tumors for EGFR high polysomy and amplification. Probe type: Dual color enumeration
