Segmentectomy for cT4 stage IIIA non-small cell lung cancer after effective chemotherapy

Abstract

We report a 70-year-old man who was referred to our hospital for stage IIIA (cT4N1M0) non-small cell lung cancer of the right lower lobe. The tumor was considered unresectable because of the patient's poor respiratory function, and so chemotherapy was initiated. The chemotherapy was effective (ycT1aN0M0), and the residual disease was resected completely via segmentectomy. Convalescence was uneventful, and the patient did not require home oxygen therapy. He remains under observation (performance status: 0) with no sign of recurrence for 12 months.
