Abstract
Abstract Introduction: Mutations in human epidermal growth factor receptor 2 (HER2) gene have been reported in lung adenocarcinoma, mainly in East Asian, American and Caucasian patients. There are no data available on the frequency of HER2 mutations in North African and Arab lung cancer patients. Materials and Methods: The mutational status of the HER2 gene was evaluated in 88 Moroccan lung adenocarcinoma patients. HER2 mutations in exon 20 were analyzed using conventional DNA sequencing. Results: One HER2 mutation was found in this series of 88 patients (1.1%). This patient was male and a heavy smoker. Conclusion: This study, the first to date dedicated to HER2-mutated North African lung adenocarcinoma patients, revealed that HER2 mutations are relatively infrequent in Moroccan lung adenocarcinomas and thus a probably limited interest of HER2 inhibitors.
