Surgical Resection of Pulmonary Metastases from Gastric Cancer；Report of a Case

はじめに　胃癌の肺転移は多発肺転移や癌性リンパ管症で発症することが多く，手術適応となることは少なく予後不良である．胃癌腹部リンパ節再発・寛解後の肺転移に対し，2回の外科的切除を行った症例を経験したので報告する．

Lung metastasis of gastric cancer often presents as multiple pulmonary metastases or cancerous lymphadenopathy, which is rarely indicated for surgery and has a poor prognosis. We report a case of solitary metastases that were surgically resected. The patient underwent distal gastrectomy for stomach cancer and then received chemotherapy for abdominal lymph node metastasis. However, he developed pulmonary metastases in the right S6 and S8, and thus underwent right S6 resection and partial resection 29 and 41 months after the gastrectomy, respectively. The pathological diagnosis was gastric cancer metastases. After undergoing surgery for resection of the metastases, he developed new metastases in abdominal lymph nodes and died 5 years after the 1st surgery.
