[A Case of an Elderly Patient with Advanced Gastric Cancer Successfully Treated with Combination S-1 and Oxaliplatin Therapy].
The patient was an 80-year-old man. He had a chief complaint of epigastric pain. The upper gastrointestinal endoscopy showed a type 4 tumor of the stomach, and the CT scan showed multiple para-aortic lymph node metastases. The patient was diagnosed with cStage IV gastric cancer. At first, he could take only small amounts of liquid. After starting S-1 and oxaliplatin (SOX), he was able to resume a full diet and his general condition was improved. A CT scan after 4 courses of chemotherapy showed a significant reduction in the wall thickness of the stomach and the size of the lymph nodes. SOX chemotherapy could be a promising treatment option for elderly patients with advanced gastric cancer.
