[A case report of distal gastrectomy with thrombectomy after NAC for Gastric cancer].
This is a case report of gastric cancer with a tumor embolus in the portal vein of a 76-year-old male. Both computed tomography (CT) and upper gastrointestinal endoscopy were performed. The diagnosis was gastric cancer with an accompanying tumor embolus in the portal vein, specifically in the superior mesenteric vein. After neoadjuvant chemotherapy, a distal gastrectomy, and thrombectomy were performed. Upon pathological examination, the main tumor was diagnosed as adenocarcinoma, and the embolus was confirmed to extend from the main tumor into the superior mesenteric vein. Upon immunostaining examination, neither the embolus nor main tumor expressed alpha-fetoprotein (AFP), but both expressed carcinoembryonic antigen (CEA). Gastric cancer with a tumor embolus in the portal vein is considered an incurable disease. However, with no other non-curative factor than portal vein embolus, it is possible that gastrectomy with thrombectomy can result in a good prognosis. On the other hand, it is extremely difficult to improve the prognosis of gastric cancer with both tumor embolus in the portal vein and liver metastasis.
