[Pulmonary Metastasis of Gastric Cancer as Carcinomatous Lymphangiosis at Five and Half Years after Surgery;Report of a Case].

A 51-year-old woman underwent radical operation for a gastric cancer and adjuvant chemotherapy with tegafur, gimeracil, and oteracil potassium. Five and a half years later, screening chest computed tomography(CT)scan showed slight ground glass opacity(GGO)of the both lungs and they were regarded as inflammatory change. Several months later, she experienced a dry cough. CT scan showed aggravation of GGO, and she was refered to our hospital to investigate these lesions 6 years after operation. We performed a wedge resection of right middle lobe. A postoperative pathology revealed metastatic carcinomatous lymphangiosis of gastric cancer. Chemotherapy using capecitabine and oxaliplatin, and then docetaxel was performed and talc pleurodesis was done for the malignant pleural effusion. These treatments did not improve condition, and she died 7 months after lung operation. In conclusion, we need to consider GGO as the possibility of carcinomatous lymphangiosis in case of patient with gastric cancer.
