进展期胃癌介入治疗疗效分析

目的研究进展期胃癌的介入治疗及疗效。方法对212例进展期胃癌进行介入治疗。对贲门癌经胃左动脉和左膈下动脉或脾动脉进行化疗灌注和胃左动脉栓塞;对胃体小弯侧癌经胃左、右动脉或肝总动脉,对胃大弯侧癌经胃十二指肠动脉、胃网膜右动脉或脾动脉化疗灌注;对胃窦癌经胃十二指肠动脉或对胃网膜右动脉中段栓塞后进行化疗药物灌注。对胃癌复发和残胃癌经腹腔干和肠系膜上动脉化疗灌注。结果对未手术的193例胃癌的疗效为贲门癌CR PR53.1%,胃体癌CR PR44.4%,胃窦癌CR PR10.0%,胃癌复发和残胃癌CR PR0。贲门癌与胃体癌有效率相比(P>0.25),两者差异无统计学意义。贲门癌与胃窦癌相比及胃体癌与胃窦癌相比,差异有统计学意义(P值均<0.05)。介入治疗后手术切除者术后1、2年生存率分别为81%、56%。结论胃癌在胃组织的发病部位不同,其疗效也不同,贲门癌和胃体癌的疗效较好,胃窦癌及胃癌复发和残胃癌疗效较差。

Analysis of interventional therapy for progressing stage gastric cancer

Objective To investigate the interventional therapy and its curative effect for progressing stage gastric cancer. Methods Two hundred and twelf patients with progressing stage gastric cancer weretreated with arterial perfusion and arterial embolization. Gastric cardia cancer was treated through the left gastric artery and the left inferior phrenic artery or splenic artery. Cancers of lesser and greater gastric curvature was treuted eigher through the left and right gastric arteries or common hepatic artery or through gastroduodenal artery, right gastroomental artery or splenic artery. Gastric antrum cancers were perfused through gastroduodenal artery or after the middle segmental embolization of right gastroomental artery. Results One hundred and ninty three cases undergone interventional management were followed up. The CR PR of gastric cardia cancer was 53.13%; gastric body cancer 44.44%; gastric antrum cancer 10%; recurrent cancer and remnant gastric cancer 0. There was no significant difference in outcome between gastric cardia cancer and gastric body cancer(P > 0.05)but significant differences were shown both between gastric cardia cancer and gastric antrum cancer, and between gastric body cancer and gastric antrum cancer(P < 0.05), with 1 year and 2 years survival rates of 81% and 56% respectively. Conclusion The interventional therapeutic effect of progressing stage gastric cancers is different due to the different sites of the lesions in the gastric tissue. The curative effect of gastric cardia cancer and gastric body cancer is better than that of gastric antrum cancer, recurrent cancer and remnant gastric cancer.
