[A Case Report of Lung Resection for Lung Metastasis from Pancreatic Cancer]

A 66-year-old man had an elevated CEA level. Further examinations showed a pancreatic head tumor. A pancreaticoduodenectomy was then performed. The histopathological examination showed a mixed tumor of papillary adenocarcinoma and neuroendocrine cancer. In addition, a tumor in the upper lobe of the right lung was found 18 months after the initial pancreatic resection, and the bronchoscope indicated lung metastasis. The patient underwent partial pneumonectomy. After the pneumonectomy, he received S-1 chemotherapy. Thirty -nine months after the pneumonectomy, CEA was slightly elevated. We changed the chemotherapy to gemcitabine and nab-paclitaxel without further examinations to confirm the recurrence. The patient discontinued chemotherapy after CEA fell within the normal range. He has been alive without tumor relapse for 64 months since the second operation for the lung metastasis. We report a successful case of lung resection for lung metasta- sis from pancreatic cancer.
