[Single-stage operation for synchronous bilateral multiple lung cancer through median sternotomy]

An asymptomatic 65-year-old woman was incidentally found to have abnormal shadows on a chest X-ray during a medical examination. A chest computed tomography (CT) scan showed a pulmonary nodule in both right and left lung. Those were diagnosed as synchronous cStage IA bilateral lung cancer, and right upper lobectomy and segmentectomy of the left lung with lymphoadenectomy were sequentially performed through median sternotomy. The patient showed a favorable course after surgery, and was discharged on postoperative day 12. The pathological diagnosis was synchronous lung cancer and both were adenocarcinoma. The pathological stage was IA on the right side and IB on the left. A single-stage operation through median sternotomy was a useful surgical procedure for treating this case of synchronous bilateral lung cancer.
