Abstract Text | We present a patient with lung adenocarcinoma showing high PD-L1 expression and BRAF V600E mutation, who achieved a remarkable long-term response to the combination therapy of dabrafenib and trametinib (DT treatment) after disease progression on immunotherapy. This case may provide an opportunity for clinicians to consider the order of administration of immunotherapy and molecular targeted therapy for BRAF V600E-positive lung cancer. |
