食管癌是常见的消化道肿瘤,同期放化疗是不能手术的食管癌常用治疗手段[1]。恶性食管瘘是食管癌性组织在食管和气道之间(食管气管瘘)或者食管和纵膈之间(食管纵膈瘘)形成的瘘口,死亡率高,其最终结局常常为支气管肺炎、败血症或大出血[2]。恶性食管瘘曾被认为是放化疗相对禁忌证,较少有相关报道[3]。本科收治的恶性食管瘘患者40例,32例顺利完成了放射治疗和化学治疗,瘘管闭合。现总结资料如下。

1 资料与方法

1.1 一般资料 选取2010年1月-2012年12月本科收治的食管癌合并恶性食管瘘患者40例,其中男34例,女6例,年龄41~80岁,中位年龄58岁。患者诊断均为食管鳞状细胞癌,其中21例为T3期,16例为T4期,均无远处转移或腹腔淋巴结转移,均不能手术,使用同期放化疗进行治疗。治疗前或治疗期间出现恶性食管瘘,其中18例出现在放化疗前,22例出现在放化疗期间。

1.2 方法

1.2.1 放化疗方案 所有患者使用3D-CRT进行放射治疗,治疗计划由Pinnacle计划系统计算。患者辐射总量中位数为54 Gy(40~68 Gy)。重要脏器的辐射剂量限制设置如下:脊柱<46 Gy,肺部平均剂量<17 Gy,V20<30%。

7例患者使用2个疗程的顺铂、5-Fu联合化疗,顺铂的剂量为20 mg/(m2·d),5-Fu的为500 mg/(m2·d),在放疗第1~5天和第29~33天时使用。另外33例患者使用多西他赛进行治疗:10例患者进行2个疗程的多西他赛和顺铂,其中多西他赛剂量为60 mg/m2,顺铂为60 mg/m2,在放疗第1天和第29天执行;23例每周同期进行顺铂化疗25 mg/m2和多西他赛25 mg/m2化疗,持续4~6周。

1.2.2 营养风险筛查 本研究采用营养风险筛查(Nutrition Risk Screening,NRS)进行营养评估[4]。患者入院后24 h内由管床护士对患者进行营养风险筛查。总分大于等于3分,表示患者有营养风险,转介营养专科护士,实施营养治疗;总分小于3分,表示患者目前没有营养风险,由管床护士每周进行营养风险再评估,必要时予预防性营养治疗。

1.2.3 营养干预 患者出现食管瘘后,使用肠内营养进行营养补充。其中22例使用鼻胃管、18例使用经皮胃造瘘管。肠内营养素根据体重配制,初始配制设计如下:能量摄入量为30 kcal/(kg·d),初始蛋白质的摄入量为1.2~1.5 g/(kg·d)。持续监测体重,调整营养素摄入量,保持体内能量和蛋白质的平衡,减少体重丢失。患者如有添加食物,应减去等量营养值的营养液。

2 结果

40例恶性食管瘘的患者中,32例(80.0%)瘘管闭合,2例(5.0%)治疗期间大出血死亡,6例(15.0%)治疗结束后瘘管未闭合予出院定期复查。本研究初次NRS得分显示,22例患者治疗前为2~3分(中到重度营养不良状态),治疗结束后16例患者的NRS得分显示提高。治疗结束后中位随访时间18个月(3~39个月),随访期间2例患者(5.0%)在瘘管关闭后出现了再次穿孔。放化疗治疗期间发生频率最高的副作用为呕吐、中性粒细胞下降、食管炎和咳嗽,大多数为1~2级。40例患者中,有8例(20.0%)出现3级及以上的呕吐,11例(27.5%)患者出现3级及以上的中性粒细胞减少,13例(32.5%)患者出现3级及以上的咳嗽。

3 讨论

营养不良是癌症患者常见并发症,大部分癌症患者在疾病进展过程中出现体重下降,甚至恶液质[5]。其原因有:(1)肿瘤代谢增加食管癌患者机体能量消耗;(2)食管癌肿瘤位置容易导致患者出现吞咽困难,营养的摄入不足[6];(3)治疗(如手术、放射治疗、化学治疗)改变机体内环境,增加食管癌患者能量和蛋白质的需求;(4)治疗相关性厌食、黏膜炎、呕吐等影响营养的摄入和吸收[6]。目前普遍认为不能手术的晚期食管癌患者进行同期放化疗能提高患者的生存率,但同时会增加患者体重丢失,增加免疫消耗,降低身体抵抗力[7-10]。食管癌行放化疗的患者的基础营养状态是患者预后的重要影响因素[11-12]。根据欧洲临床营养和代谢学会(European Society for Clinical Nutrition and Metabolism,ESPEN)指南对正在进行放射治疗或放化疗的患者的肠内营养,应努力增加营养的摄入,预防治疗相关性体重丢失和治疗的中断[13]。但监测体重再进行营养补充往往具有滞后性,不能提前预测体重减轻的风险。

营养干预虽然不能针对性治疗肿瘤组织或细胞,但营养治疗作为基础治疗能够为抗肿瘤治疗或手术治疗提供良好的身体基础,提高机体的自身免疫及对放射治疗和化学治疗的耐受能力[14]。本研究中营养方案的制定前充分评估了患者的营养状态,肿瘤类型,预测对治疗的反应以及耐受情况,针对性选用经口进食、肠内营养、静脉营养为患者提供营养支持。本研究中食管癌合并食管瘘的患者,为避免食物经食管瘘口进入气道或纵膈加重感染,均予以禁食,予肠内营养支持(18例经鼻胃管,22例经胃造瘘管)。多项研究表明肠内营养能为患者提供充足的营养支持,不仅能增加患者的体重,提高患者对治疗的反应,还能提高患者的生活质量[14-15]。endprint

NRS营养风险筛查能有效区分和检测患者的营养状况,及时、充足的肠内营养支持能有效增加患者对放化疗的耐受性,完成相关治疗,并促进瘘口的愈合,值得临床推广。
