简介：【摘要】目的 分析在结直肠癌患者出现不可切除的肝转移瘤治疗当中，实施精准序贯介入治疗的效果。方法 选择我院 2018年 1月～ 2019年 6月收治的 38例结直肠癌且出现不可切除肝转移瘤患者进行分析，将其均匀分成对照组（ 19例）和观察组（ 19例），对照组接受常规化疗治疗，给予观察组对象精准序贯介入治疗，对两组对象的治疗效果进行分析。结果 观察组对象的整体疗效要好于对照组，且数据进行分析后存在统计学差异（ P<0.05）。结论 对于出现不可切除肝转移瘤的结直肠癌患者，让其术后接受精准序贯介入治疗的效果较好，值得实施。  　　【关键词】结直肠癌 ;肝转移瘤 ;精准序贯介入 ;效果 ;化疗  　 [Abstract] Objective To analyze the effect of precise sequential interventional therapy in the treatment of unresectable liver metastases in patients with colorectal cancer. Methods 38 cases of colorectal cancer patients with unresectable liver metastases in our hospital from January 2018 to June 2019 were selected for analysis, and they were evenly divided into control group (19 cases) and observation group (19 cases). The control group received conventional chemotherapy, and the observation group received precise sequential interventional therapy. The treatment effects of the two groups were analyzed. Results the overall curative effect of the observation group was better than that of the control group, and there was statistical difference after data analysis (P < 0.05). Conclusion for colorectal cancer patients with unresectable liver metastases, the effect of precise sequential interventional therapy after operation is better, which is worthy of implementation.
