本文报告在食管癌高发区姚村公社对普查发现的早期食管癌33例观察的远期结果。病例分为两组,化学治疗组的五年生存率为87％,中位病程为90.5月;未治对照组的五年生存率为35％,中位病程为4个月。经统计学处理两组具有显著差异,说明化疗可延长早期病例的生存期,此结果提示早期食管癌的化学治疗是可行的。
This article reports on the long-term results of observations of 33 cases of early esophageal cancer found in the census conducted by Yao Cungong, a high-risk area of esophageal cancer. The cases were divided into two groups. The five-year survival rate in the chemotherapy group was 87%, and the median course was 90.5 months. The untreated group had a five-year survival rate of 35% and a median disease course of 4 months. The statistically significant difference between the two groups shows that chemotherapy can prolong the survival of early cases. This result suggests that early chemotherapy for esophageal cancer is feasible.
