贲门失弛缓症并发食管癌,近年来的报导略有增加,在发病因素及临床诊断上还应进一步探讨。发病率及发病因素贲门失弛缓症并发食管癌的发病率,Mathews报道在1,000例贲门失弛缓症中发生3例,发生率0.3％。多数报道发生率在3.3％左右。在年龄发病率上,按平均年龄计算,Boliver报告为52岁,Hankins报告为55岁。在平均病期上,Williams报告17.7年,Pierce报告为23年。由此可见,年龄大和病期长说明并发癌的过程较长。癌的发生部
Cardiac achalasia complicated by esophageal cancer, a slight increase in recent reports, in the pathogenesis and clinical diagnosis should be further explored. Incidence and incidence of achalasia associated with esophageal cancer incidence, Mathews reported 1,000 cases of cardia achalasia occurred in 3 cases, the incidence of 0.3%. The incidence of most reports is about 3.3%. In terms of age, Boliver reported a mean age of 52 years and Hankins reported 55 years old. On average, Williams reported 17.7 years and Pierce reported 23 years. Thus, older and longer duration of cancer shows that the process of longer. Occurrence of cancer
