The case of double primary lung adenocarcinomas with an EGFR mutation and ALK translocation successfully treated with alectinib at the post-surgicalrecurrence
A 36-year-old male was found two nodules in the right lower lobe of the lung. After the surgical resection, both lesions were diagnosed as invasive adenocarcinomas. One lesion was primarily lepidic growth component with EGFR-L858R mutation, and the other was micropapillary component with ALK translocation accompanying mediastinal lymphnode metastases. While he experienced disease recurrence, the disease was controlled by an ALK inhibitor, given based on the findings of surgical specimens. This is the first case who had two simultaneous lung cancers with EGFR mutation and ALK translocation in each respective lesion, and was successfully treated with ALK inhibitor at the post-surgical recurrence.
