近几十年来可切除胃癌的长期生存率未取得明显改善。尽管在发展辅助治疗上进行了努力，但大量随机试验表明静脉化疗或放疗对提高生存率无效。分析治愈性切除后复发的方式中，局部和腹腔内复发对生存率有影响，约50％的患者前述部位是首次复发的唯一部位，甚至到死亡时，肿瘤也? The long-term survival rate of resectable gastric cancer in recent decades has not been significantly improved. Despite efforts to develop adjuvant therapies, a large number of randomized trials have shown that intravenous chemotherapy or radiotherapy is not effective in improving survival. In the analysis of recurrences after curative resection, local and intra-abdominal recurrences have an impact on survival. About 50% of patients have the first site of their first recurrence. Even when they die, the tumors are also affected.
