RESUMEN
A 76âyearâold man was introduced to our hospital after being suspected of having early gastric cancer with an upper gastrointestinal endoscope that was performed to find the cause of anemia. Two cancers were revealed: type 0ââ ¡a+â lesion in the lesser curvature of the upper body and type 0ââ ¡a+â ¡c lesion in the greater curvature of the middle body. The blood test showed abnormalities(hemoglobin, 6.8 g/dL; platelets, 26,000/µg). Thus, myelodysplastic syndrome(MDS) was suspected, and since this was prioritized over gastric cancer, the patient was transferred to the hematology department. As high risk MDS was diagnosed, azacitidine therapy was initiated. After 2 cycles of treatment, the blood abnormalities improved(hemoglobin, 11.3 g/dL; platelets, 254,000/µg). ESD was performed in our department for the 2 lesions. Histopathological examination showed that both lesions represented wellâdifferentiated adenocarcinoma, and so radical resection was performed. Since MDS occurs due to aging and is common among patients, we believe that timely treatment is necessary.

A 69-year-old woman presented with persistent nauseous, underwent upper gastrointestinal endoscopy, and was diagnosed with type 2 advanced gastric cancer at the antrum. Abdominal contrast CT image data revealed that there was a large, swollen, pancreatic superior lymph node invading the common hepatic artery. We determined that the tumor was unresectable and systemic chemotherapy was performed using S-1 plus oxaliplatin(SOX)therapy. After 5 courses of chemotherapy, the abdominal contrast CT image data indicated reduction of both the primary lesion and lymph node metastasis. A laparotomy was performed. As the No. 8a lymph node was forming hard scar tissue, we could not dissected clearly it from the common hepatic artery wall. We strongly suspected that cancer tissue remained at the artery wall. A distal gastrectomy and Roux-en-Y reconstruction were performed. Histologically, the resected specimen was determined to be Grade 3, with a pathological complete response(pCR). The patient was administered S-1 for 6 months after the operation and has enjoyed 2.5 years of recurrence-free survival. SOX therapy for unresectable gastric cancer and surgical intervention as conversion surgery were effective. This case demonstrated the possibility of life prolongation using these therapies.
