Adenocarcinoma with epidermal growth factor receptor gene mutations in three siblings.
Overview
abstract
Sensitivity to an inhibitor of epidermal growth factor receptor (EGFR) kinase strongly correlates with EGFR somatic mutations in non-small cell lung cancer. These mutations are frequently found in patients with adenocarcinoma, never- or light-smokers, women, and East Asians. In this study, we show an aggregation of three non-small cell lung cancer cases with EGFR gene mutations in one family. The subjects were all female, never- or light-smokers with adenocarcinoma. Two of the patients responded to treatment with gefitinib. A genetic study of these cases would be useful in elucidating genetic susceptibility to lung cancer in persons with EGFR mutations.
