约半数的食管或胃贲门癌确诊时已处于晚期而不能手术,而通过放置支架可缓解吞咽困难症状,但问题不少。近有应用Nd-YAG激光以气化肿瘤而使管腔再通,但仍易复发,需每隔4～6周重复治疗。加用放疗可推迟其复发时间。 方法:英国伦敦Middlesex医院于1993～1996年共对22例进展期食管或胃贲门癌(男12例,女10例,中位值年龄83岁,肿瘤中位值长度7cm)采用激光治疗,凡吞咽改善并能进食半固体饮食者即随机分成两组进行研究。一组不作任何
Approximately half of the esophageal or gastric cardia cancers are already in advanced stages of diagnosis and can not be surgically treated, and stenting can relieve the symptoms of dysphagia, but there are many problems. Nearly the application of Nd-YAG laser gasification of the tumor and the lumen recanalization, but still easy to relapse, need to be repeated every 4 to 6 weeks treatment. Plus radiotherapy can delay the recurrence time. METHODS: Twenty-two patients with advanced esophageal or gastric cardia cancer (including 12 males and 10 females with a median age of 83 years and a median tumor length of 7 cm) were treated with laser from 1993 to 1996 at Middlesex Hospital, London. Swallowing improved and can eat semi-solid diet who are randomly divided into two groups to study. A group does not make any
