Prospective Study of the Accuracy of EGFR Mutational Analysis by High-Resolution Melting Analysis in Small Samples Obtained from Patients with Non–Small Cell Lung Cancer

Purpose: Epidermal growth factor receptor (EGFR) mutations, especially in-frame deletions in exon 19 (DEL) and a point mutation in exon 21 (L858R), predict gefitinib sensitivity in patients with non–small cell lung cancer (NSCLC). In this study, we verified the accuracy of EGFR mutation analysis in small samples by high-resolution melting analysis (HRMA), which is a rapid method using PCR amplification with a dye to analyze the melting curves in...
