title: [A case of synchronous bilateral double primary lung cancer successfully treated by Nd-YAG laser therapy and chemotherapy].
abstract: A 61-year-old man was admitted to our hospital with the chief complaint of hemosputum. He was a heavy smoker. A chest radiograph revealed a tumor shadow in right S3 which invaded the pulmonary artery. There was also an associated patchy shadow in the periphery as well as ipsilateral pleural effusion. Bronchoscopy revealed a near occlusion with superficial infiltration at the right B3 bronchus and a nodular tumor at the bifurcation between the left upper and lingual division bronchi, which was consistent with endoscopic early lung cancer. Although both tumors were histologically diagnosed as squamous cell carcinoma, this was considered to be a case of synchronous double primary lung cancer due to their mutual isolation. The left tumor was subsequently diagnosed as carcinoma in situ. Following Nd-YAG laser therapy for carcinoma in situ and 4 courses of systemic chemotherapy using TXT and CDDP, bronchoscopy revealed no residual cancerous tissue and no tumor apart from the nodular shadow in right S3 was seen on a radiograph. Subsequent right upper and middle lobectomy and lymph node (R2a) dissection revealed no residual tumors.
