[A Case Report of Advanced Gastric Cancer Demonstrating CR after Treatment with S-1 and Paclitaxel].

Here, we report a case of advanced gastric cancer that demonstrated CR after treatment with S-1 and paclitaxel. The patient was an 80-year-old woman with gastric cancer in whom upper gastrointestinal endoscopy (GIF) revealed a type 3 tumor in the cardia of the stomach that was pathologically diagnosed as a well-differentiated adenocarcinoma. Computed tomography showed no lymph node involvement or metastasis. Considering her advanced age and cardinal functional disorder, she was administered chemotherapy consisting of S-1 and paclitaxel. Depending on a state, a side effect, I changed a dose and inter-dose interval from head to foot and I treated it by foreign going to hospital and continued it. Gradual tumor reduction was observed on GIF (2011/1/25). CR was diagnosed without tumor disappearance, with accepted malignant findings on biopsy. The patient has now survived for 7 years 9 months after diagnosis. The present case demonstrates that combination therapy of S-1 and paclitaxel is safe and useful for patients with risk factors such as advanced age and underlying disease.
