The Prognostic Effect of the Epidermal Growth Factor Receptor Gene Mutation on Recurrence Dynamics of Lung Adenocarcinoma

Park and colleagues genotyped cancer tissue for epidermal growth factor receptor (EGFR) mutations in patients with complete resection for lung adenocarcinoma who had a recurrence. Lung adenocarcinoma with EGFR gene mutations was associated with a longer disease-free interval than was the wild-type EGFR gene. Additionally, EGFR gene mutation was a prognostic factor for disease-free interval.
