胃癌术中动脉区域灌注化疗与全身静脉化疗的临床疗效比较

目的　评价胃癌术中动脉区域灌注化疗药物的临床疗效。方法　对 40例经病理确诊的胃癌患者 (治疗组 )于术中经供应肿瘤的区域动脉行插管化疗 ,同时进行手术治疗 ,并与同期术中行全身静脉化疗的 2 4例胃癌患者 (对照组 )进行临床疗效比较。结果　术后病理检查显示 ,治疗组原发灶中的癌细胞均有不同程度地变性坏死 ,其近期有效率为 95 % ,对照组有效率为 41.6 7% ,两组比较差异显著 (P<0 .0 5 )。结论　胃癌患者术中经动脉灌注化疗 ,其近期抗癌效果好 ,毒副反应轻 ,对减少或防止术中癌细胞的医源性扩散与种植以及术后复发 ,均有重要的临床意义

Clinical Comparison between Intraoperative Local Arterial Infusion Chemotherapy and Systemic Venous Chemotherapy of Gastric Cancer

Objective To evaluate the effect of intraoperative local arterial infusion chemotherapy for gastric cancer. Methods The effects of intraoperative local arterial infusion chemotherapy in 40 patients with gastric cancer were assessed. Twenty four patients with gastric cancers who underwent the intraoperative systemic chemotherapy were taken as controls. The removed specimens were examined microscopically to show the degeneration and necrosis of the tumour cell. Results After the treatment of the tumour cells, all of the cases in the study group showed various degrees of degeneration and necrosis. The immediate effective rate was 95% for the the study group but only 41.67% for the control group ( P <0.05). Conclusion Intraoperative local arterial infusion chemotherapy for gastric cancer has good immediate effect and little side effect; it prevents the intraoperative iatrogenic metastases and implantation and decreases the postoperative recurrence of gastric cancer.
