Abstract
Gastric metastasis from primary lung cancers is quite rare. In such a case, resection of the affected tissue is rarely performed. We herein describe a case of resection of the abovementioned case. A 60-year-old man was found to have right massive pleural effusion. He was diagnosed with c-TxN2M1a and c-stage IV lung cancer on the basis of detailed examination combined with the presence of adenocarcinoma cells in the pleural effusion. Chemotherapy with carboplatin+paclitaxel was initiated. After three cycles of chemotherapy, the patient developed herpes zoster infection. Following this, we decided to stop chemotherapy. Two years later, he underwent a follow-up examination, and CT revealed the disappearance of the thoracic diseases and a newly developed gastric submucosal lesion, and positron emission tomography-computed tomography indicated no other lesion. Noninvolvement of surrounding structures suggested that we could perform total gastrectomy, D2 lymph node dissection, pancreatic tail resection, and splenectomy. The adenocarcinomatous nature of the gastric and lymph node metastases from lung cancer was later demonstrated pathologically. We report a rare case of resection of gastric metastasis from lung cancer. These cases are recommended for multimodality therapy, including surgical operations.
