RESUMO
This case was observed in a man in his 70s. Although symptomatic treatment was performed for epigastralgia, endoscopic examination revealed a type 3 tumor on the fornix of the stomach to the lesser curvature of the body just above the esophagogastric junction, and the patient was diagnosed with moderately differentiated tubular adenocarcinoma(cT4bN3aM0, cStage â £A). As esophageal and diaphragmatic invasion was suspected based on CT findings, S-1 plus CDDP was started as preoperative chemotherapy. Although the primary lesion and lymph node metastasis decreased in size, chemotherapy was discontinued after one course due to stenosis symptoms, and total gastrectomy and D2 dissection were performed. Postoperative adjuvant chemotherapy with S-1 was started. However, 6 months after starting the treatment, para-aortic lymph node recurrence was observed, and the treatment strategy was changed to weekly PTX. After 5 courses of weekly PTX, the lymph nodes continued to increase in size, and chemotherapy was discontinued per the patient's request. The patient was followed up with CT and PET-CT; however, no new recurrent lesions were found in other sites for approximately 1 year. Therefore, para-aortic lymph node dissection was performed as the salvage surgery. Pathological findings showed that gastric cancer metastasis was present in 1 swollen lymph node only, as confirmed by PET. At present, 6 years have passed since the first operation, and there has been no recurrence. In general, para-aortic lymph node metastasis is considered to result in poor prognosis in gastric cancer. However, in the absence of other noncurative factors, a good prognosis may be obtained with combined therapeutic modalities.
