动静脉联合给药的FLEOX新辅助化疗加营养支持提高晚期胃癌可切除率

目的总结动静脉联合给药的FLEOX新辅助化疗加营养支持对以淋巴结转移为主的晚期胃癌的手术可切除率。方法对术前CT检查发现伴有严重的第3、7、9、12组淋巴结转移、或第14、16组淋巴结转移而难以切除的50例晚期胃癌患者进行新辅助化疗：氟尿嘧啶（5．FU）370mg／m^2，静滴，第1～5天；亚叶酸钙200mg静滴，第1～5天；足叶乙苷80mg／m^2与奥沙利铂120mg／m^2经动脉注射，第6、20天；每5周重复1次。其中12例伴有中、重度营养不良者酌情进行肠外、肠内营养支持，状况好转后进行化疗，以使患者获得手术切除的机会。结果50例晚期胃癌患者的影像学及组织学评价有效率（CR加PR）为84．0％；12例伴营养不良的病例在化疗结束、拟行手术前体重均较入院时明显增加，血清白蛋白等营养指标恢复正常。手术切除率为78．0％，全组均成功进行了胃次全切除、全胃或联合脏器切除和D2＋α、D3淋巴结清扫术。结论动静脉联合给药的FLEOX新辅助化疗加合理的营养支持对以淋巴结转移为主的晚期胃癌具有满意的治疗效果。

Arteriovenous neoadjuvant FLEOX chemotherapy with nutritional support improves the resectable rate for advanced gastric cancer

OBJECTIVE: To summarize the resectable rate of advanced gastric cancer characterized by abdominal lymph node metastases with the arteriovenous neoadjuvant FLEOX chemotherapy plus appropriate nutritional support. METHODS: Arteriovenous neoadjuvant FLEOX chemotherapy was administered to 50 patients of gastric cancer with advanced abdominal lymph node metastases. Of the 50 patients, 42 had never received any previous therapy and preoperative CT scanning revealed unresectable tumors because of advanced lymph node (station No.3, 7, 9, 12) or distant lymph node (No.14,16) metastases. The other 8 were characterized with relapse of severe lymph node metastases or with unresectable lymph node metastases demonstrated by exploratory laparotomy. Arteriovenous neoadjuvant FLEOX chemotherapy was conducted as follows: from day 1 to day 5, 5-FU 370 mg/m(2) and leukovorin 30 mg/kg intravenously, at day 6 and day 20, CDDP 70 mg/m(2) and epotoside 70 mg/m(2) intraarterially. This FLEOX regimen was repeated every five weeks for two or three courses. Out of the 50 patients,12 malnutritional cases received parenteral and/or enteral nutritional support according to the nutritional condition. Arteriovenous neoadjuvant FLEOX chemotherapy was then administered after the improvement of nutritional state. Their nutritional support methods were adapted to their chemotherapy as well. RESULTS: All the patients' general conditions and symptoms were improved significantly. For the 50 cases, the imageological and histological response rate (CR+PR) was 84.0%, and curative resection rate was 78.0%. Thus, 39 patients underwent subtotal or total gastrectomy, even combined organ resection, with D(2)+alpha or D(3) lymphadenectomy. Despite neoadjuvant chemotherapy, all malnutritional cases had significant weight gain after nutritional support, and other nutritional indexes,such as serum albumin, also resumed to normal. CONCLUSION: Arteriovenous neoadjuvant FLEOX chemotherapy proves favorable therapeutic effect for gastric cancer with advanced abdominal lymph node metastases, and downstages inoperable metastatic lymph nodes for radical operation. This combined modality regimen and nutritional support may play an important role in the treatment of advanced gastric cancer.
