[A case of non-small-cell primary lung cancer invading distal aortic arch and left subclavian artery].

A 71-year-old male patient was referred to our institute for abnormal mediastinal shadow. It was proved to be squamous cell carcinoma arising in left S1 + 2 and involving distal aortic arch and left subclavian artery (T4N2M0 Stage IIIB). The cancer responded well to the preoperative induction therapy and it was resected completely with associated resection of distal aortic arch and left subclavian artery. Both arteries were replaced with Dacron grafts. With induction therapy and extended operation, this patient of non small cell T4 primary lung cancer is expected to acquire long term survival.
