晚期食管癌内支架术后放射治疗

Radiotherapy of Patients with Late Stage Esophageal Carcinoma after Stent Inserted

目的 :研究高度狭窄的晚期食管癌 ,金属被覆内支架术后的放射治疗。方法 :2 1例呈程度不同恶病质状态的晚期食管癌 ,狭窄均在 2mm以下 ,其中 7例呈梗阻状 ,4例伴食管瘘。共置放 2 2个镍钛合金被覆内支架 ,2周后行外照射 ,DT 60～ 70Gy。结果 :支架全部顺利置放成功 ,2周后均能进普食 ,并顺利接受根治性放射治疗 ,未出现白细胞降低等并发症。于放疗后随访复查 :9个月 7例 ,12个月 9例 ,15个月 5例。支架原位 ,其上下界未出现狭窄 ,管腔通畅 ,患者进食顺利 ,体重增加。结论 :高度狭窄的晚期食管癌内支架术后 ,经放射治疗 ,可取得满意的近期疗效。

Objective: To evaluate the therapeutic effect of radiotherapy of late stage esoophageal cancer after stent placement Methods: Twenty-one cases of advanced esophageal cancer with lumen stenosis less than 2mm in diameter Seven of them had complete obstruction and 4 with fistula Twenty-two nitinol stents were inserted to the site of stenosis and then radiotherapy of Co60 (DT 60～70Gy) was given two weeks later Results: The postradiotherapy follow-up at 9 months in 7 cases, 12 months 9 cases and 15 months 5 cases showed that all the patients could take full diet two weeks after stent placement No narrowing recurrence occurred and the patients gained weight following uneventful taking food Conclusion: The stent placement with radiotherapy is helptul in the treatment of late stage esophageal cancer and a short-term good result can be achieved
