[摘要] 目的 探讨区域性动脉灌注新辅助化疗治疗进展期胃癌的疗效。 方法 回顾性分析82例临床Ⅲ、Ⅳ期胃癌患者接受区域性动脉灌注新辅助化疗(动脉灌注化疗组,42例)和静脉新辅助化疗(静脉化疗组,40例)的疗效, 术前共2次,间隔28 d。两组均在第2次化疗后10~15 d接受手术。术后接受6个疗程的化疗。比较两组化疗毒副反应及生存率。 结果 两组化疗毒副反应无明显差异,两组中位生存期(动脉组25.3个月vs 静脉组19.1个月)、3年生存率(动脉组36.4% vs静脉组21.0%)比较差异存在统计学意义(P<0.05)。 结论 区域性动脉灌注新辅助化疗耐受性良好,有助于提高进展期胃癌患者的生存率。

[Abstract] Objective To evaluate the effects of preoperative regional intra-arterial infusion chemotherapy for patients with advanced gastric cancer (AGC). Methods A total of 82 patients with clinical stage Ⅲ, Ⅳ gastric cancer received two cycles of neoadjuvant regional intra-arterial infusion chemotherapy (arterial infusion group, n=42) or neoadjuvant systemic chemotherapy (systemic chemotherapy group, n=40). The operation was administrated in 10 to 15 days before chemotherapy. All patients received 6 course of systemic chemotherapy after surgery. Chemotherapy toxicity and survival rate were retrospectively analyzed. Results No significant difference was found in chemotherapy toxicity between two groups. The median survival period was 25.3 months in arterial infusion group and 19.1 months in systemic chemotherapy group. 3-year survival rate was 36.4% in arterial infusion group and 21.0% in systemic chemotherapy group respectively, there were significant differences (P<0.05). Conclusion Preoperative regional intra-arterial infusion chemotherapy is well tolerated in advanced gastric cancer patients and could improve short-term survival.

在我国超过80%的胃癌患者就诊时即为进展期,根治性切除率低,而后续化疗等抗肿瘤治疗敏感性较差[1,2]。提高Ⅲ、Ⅳ期患者的手术切除率并延长其生存期是目前临床亟需解决的难题。随着胃癌多学科治疗模式的演变,从以往单一的手术切除进入以围手术期辅助治疗加规范化手术的新模式,新辅助化疗已成为进展期胃癌治疗的重要组成部分,但局限于化疗药物的敏感性,治疗效果仍不尽如人意。为探索给药途径对新辅助化疗疗效的影响,我院2003年1月~2007年12月对82例Ⅲ、Ⅳ期胃癌患者通过术前区域性动脉灌注化疗、新辅助静脉化疗后再手术治疗,现对比分析两组的治疗效果,报道如下。

1.1 临床资料
回顾性研究本院2003年1月~2007年12月间82例经胃镜活检病理证实为胃腺癌,且增强CT检查判断临床分期[3-5]为Ⅲ、Ⅳ期的患者,其中男60例、女22例,年龄29~77岁。……
