Multiple targets, germline BRCA1 mutation and HRD in a lung cancer patient: Molecular considerations and treatment decision-making

Introduction: Several biomarkers are currently available to address targeted treatments in cancer patients, with lung malignancies representing one of the best examples. Case description: We report the case of a patient affected by advanced non-small cell lung cancer with an uncommon histology and a complex biology. The use of a large next-generation sequencing (NGS) NGS panel allowed us to identify an extremely rare BRAF mutation (V600Q), a MET amplification, a high tumor mutational burden, a germline pathogenetic BRCA1 mutation and a homologous recombination deficiency through RAD51 assay. The treatment decision was driven by the abundance of molecular information. Conclusions: This case highlights that an attentive and critical evaluation of molecular reports is key for the tailoring of treatment algorithms at the patient-level scale.
