简介:目的探讨下咽癌侵犯食管上端的治疗效果.方法回顾性分析1998年1月至2003年1月间17例侵犯食管上段的下咽癌病例.根治性放疗8例,手术加放疗9例,其中2例行下咽、全喉、全食管切除,咽胃吻合术,7例行下咽、全喉、食管上端切除、舌瓣和胸大肌肌皮瓣重建下咽及颈段食管;8例伴行双侧颈清扫术,1例同侧颈清扫术.全部病例术后随访.结果9例手术加放疗患者8例均能经口进食,日常生活自理;1例吻合口狭窄;5例已死亡,中位生存期29个月;8例单纯根治性放疗者6例已死亡,中位生存期13个月.结论下咽、全喉、全食管切除,胃咽吻合术或下咽、全喉、食管上端切除、舌辨和胸大肌肌皮瓣重建下咽及上段食管加术后放疗,治疗下咽癌侵犯上端食管的方法可行,预后较单纯放疗好,应采用积极的治疗方法,但生活质量欠满意.
