51岁男子吞咽困难泄露肿瘤踪迹

2017-08-30 05:51:55   中国青年网

3年前,51岁的张先生因总感觉吃东西时吞咽困难、“哽”得慌而到医院就诊,让他没想到的是最终拿到的诊断结果竟是晚期食道癌。颅脑CT检查显示张先生食道中下段病变长约10厘米,由于肿瘤浸润食管太长,一家人来回跑了多家医院均被告知无法手术,治疗的难度较大。

最后在朋友的介绍下,张家人抱着“试试”的态度找到武汉市第五医院肿瘤科龙志雄教授。根据张先生的病情,龙教授带领团队为他制定了个体化的精确放疗方案。一个疗程的食道病灶立体定向放疗后,张先生进食梗阻症状明显消失,并能像以前一样进食。现在他的病情控制得很理想,日常生活基本不受影响。

我国每年约15万人

死于食道癌

食道癌是常见的消化道肿瘤,全世界每年约有30万人死于食道癌。我国是世界上食道癌高发地区之一,每年平均病死约15万人。男多于女,发病年龄多在40岁以上。食道癌典型的症状为进行性咽下困难,先是难咽干的食物,继而是半流质食物,最后水和唾液也不能咽下。龙志雄教授解释说:“目前来看,食道癌治疗方法主要还是外科治疗、放射治疗、化学治疗和综合治疗四种。手术虽然是首选,但限制条件较多,特别是对于那些晚癌患者,肿瘤侵犯范围较大,根本无法手术,对于这一类患者建议选择立体定向放疗。”

无法手术的晚癌患者,

立体放疗优势明显

据龙主任介绍,过去,利用常规放疗技术治疗食道癌效果一直不太理想。然而在近二十多年,随着影像学的进展,计算机的应用,尤其是放疗设备本身的发展,放疗的地位和作用已发生了翻天覆地的变化。

“如果把常规放疗比喻为火炮时代,那么现代放疗则已经进入了精确制导的导弹时代,它的精度更高,局部能量的聚焦性更强。在这样一个全面技术提升的背景下,食道癌立体放疗的效果也相应大幅度提升。”龙主任强调,就食道癌患者来说,立体放疗最大的优势在于能控制转移瘤的发展延长其生存期,可起到减少肿瘤负荷、改善生活质量、增强免疫的作用。
