目的: 通过腹部动脉介入化疗和腹腔化疗的联合应用, 探讨预防胃及结肠癌术后腹腔内复发和腹腔内脏器转移的治疗方法.材料和方法:对22 例经手术病理证实的胃及结肠癌进行了术后的胃肠道动脉化疗和腹腔化疗,并予跟踪随访.结果: 部分病人肝内转移灶缩小或消失; 部分伴腹部淋巴结转移者,CT 复检转移淋巴结减小或消失;病人生活质量明显改善.结论:本法明显提高了肿瘤区域的化疗药物浓度,对肿瘤细胞的杀死率明显高于其它方法.尤其是对肝内的转移灶,通过对靶血管的栓塞,使肿瘤细胞缺血坏死.对于腹腔内游离癌细胞、腹膜面和切口区域的肿瘤细胞,可直接作用并杀死.联合治疗的安全性高、伤害小.能够有效防止腹腔内的复发和腹内脏器的转移.“,”Purpose:To evaluate the metastasis to other organs after gastric and colonic carcinomas were excised.The joint treatment of interventional transarterial infusion and intraperitoneal chemo-perfusion were used. Materials and Methods:22 patients with gastric and colonic carcinomas proven by operative histology were carried on transarterial and abdominal cavity chemotherapy.Results:The lessening and disappearance of metastatic liver carcinomas did ocurr for some patients.Also the decrease and disappearance of metastatic abdominal lymph nodes are occurred for some patients.Living quality of patients were obviously better then.Conclusion:The method can increase the consistency of chemotherapeutant in tumor areas,and was evidently more effective than others in killing tumor cells.To deal with the metastatic liver carcioma,embolism to target artery was used to induce necrosis of the cancer cells for lack of blood supply.As those of cancer cells drifting in the patients'abdominal carity,on the surface of peritoneum or around the vicinity regions,would be killed them immediately.This joint chemotherapy is quite safe ,moreover, can effectively prevent cancer recurrence in abdominal cavity or metastasis to other organs.
