[Long-Term Survival after Reoperation for Lung Metastasis of Resected Pancreatic Adenocarcinoma - A Case Report].

A 66-year-old woman with pancreatic cancer underwent resection of the pancreatic body and tail. Thirty-seven months after the initial surgery, a tumor was found in S4 of the right lung, for which resection of the middle lobe of the lung was performed. A diagnosis of lung metastasis originating from pancreatic cancer was confirmed based on histological and immunohistopathological assessments. Sixty-seven months after the initial surgery, despite the gemcitabine-based adjuvant chemotherapy, a tumor was detected in S3 of the left lung, for which partial lung resection was performed. Similar to the previous diagnosis, the tumor was diagnosed as lung metastasis of pancreatic cancer on the basis of the pathological findings. After the third operation, despite gemcitabine and S-1 chemotherapy, widespread pulmonary metastasis developed. One hundred and thirty months after the initial surgery, the patient died of respiratory failure due to carcinomatous pleurisy.
