据《The Journal of the American Medicel Association》1995年274卷第17期报道为对贲门失驰缓症病人患癌症的危险性进行更确切的评估,美国北卡罗来纳大学Sandler医师等对1964～1989年瑞典以人口为基数的住院病人中所有贲门失驰缓症者进行了队列研究。共对1062例贲门失驰缓症者进行了9864人年的随访。开始随访时的平均年龄为57.2岁,确诊为癌时的平均年龄为71.0岁。其中24人患食管癌。在确诊贲门失驰缓症后的第一年发生食管癌的危险性极高[标准化发生率(SIR)为126.3,95％可信限(CI)为63.0～226.1],这
According to the “The Journal of the American Medice Association,” Volume 274, 1995, No. 17, reported a more accurate assessment of the risk of cancer in patients with cardia dementia, Sandler, University of North Carolina at the University of 1964 to 1989 Sweden A cohort study was conducted on all patients with cardia deafness in a population-based inpatient population. A total of 1062 cases of cardia deacetylase were 9864 years of follow-up. The average age at follow-up was 57.2 years and the mean age at diagnosis of cancer was 71.0 years. 24 of them suffer from esophageal cancer. The risk of esophageal cancer in the first year after diagnosis of cardia deacetylase was extremely high (standardized incidence (SIR) = 126.3, 95% confidence interval (CI) = 63.0 to 226.1)
