A 66-year-old man underwent chemotherapy with S-1 plus cisplatin plus trastuzumab to treat advanced gastric cancer that was diagnosed as cStage Ⅳ adenocarcinoma(T3N1M1[P0, CYX, H1]). After 8 courses, liver metastases were absent on contrast-enhanced MRI. The patient underwent a laparoscopic distal gastrectomy with D2 lymphadenectomy. The gross appearance of the surgically resected specimen showed a shrunk gastric tumor measuring 1 mm. The postoperative course was uneventful, and the patient has been well, receiving maintenance chemotherapy of S-1 plus trastuzumab without evidence of recurrence for 15 months following the operation. Conversion surgery following chemotherapy might be an effective treatment for patients with advanced gastric cancer; however, further studies are needed to establish this treatment strategy.
一名66岁男性接受了S-1联合顺铂及曲妥珠单抗化疗，以治疗诊断为c期Ⅳ腺癌（T3N1M1[P0, CYX, H1]）的晚期胃癌。8个疗程后，对比增强MRI显示无肝转移。患者接受了腹腔镜远端胃癌根治术及D2淋巴结清扫术。手术切除标本的大体外观显示胃肿瘤缩小至1毫米。术后过程顺利，患者情况良好，术后15个月接受S-1联合曲妥珠单抗维持化疗，无复发迹象。化疗后进行转化手术可能是晚期胃癌患者的一种有效治疗方法；然而，需要进一步研究以确立这种治疗策略。
