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.
Insights
Dabrafenib plus trametinib shows efficacy in advanced non-small cell lung cancer (NSCLC) with uncommon BRAF mutations. Comprehensive genomic profiling is crucial for identifying these rare alterations.
Area of Science:
- Oncology
- Genetics
- Pharmacology
Background:
- BRAF V600E mutations are common drivers in lung adenocarcinoma, with targeted therapies like dabrafenib plus trametinib approved for advanced NSCLC.
- Efficacy data for dabrafenib plus trametinib against rare BRAF mutations in NSCLC are limited due to their infrequent occurrence.
