Response to dabrafenib plus trametinib on a rare BRAF mutation (V600_W604 deletion–insertion R) in an advanced non‐small cell lung cancer patient
Abstract
Abstract Although dabrafenib plus trametinib has been approved for BRAF V600E mutation positive advanced non‐small cell lung cancer (NSCLC), data on its efficacy against uncommon BRAF mutations are still limited due to their rare frequency. We report a case of 70‐year‐old woman with BRAF V600_W604 deletion–insertion R‐positive stage IVA lung adenocarcinoma, who was successfully treated with dabrafenib plus trametinib. Herein, we discuss the oncogenic role of uncommon BRAF mutations and highlight the importance of performing comprehensive genomic profiling on patients without any targetable gene alterations in companion diagnostics.
