摘　　要：对食管上皮细胞正常（以下简称正常）、食管上皮细胞轻度增生（以下简称轻度增生）和食管上皮细胞重度增生（以下简称重度增生）共46161例进行了癌变时间和癌变率的研究结果说明：食管癌变平均时间的频率差异为重度增生癌变平均时间3年7月＜轻度增生癌变平均时间5年4月＜食管正常癌变平均时间8年10月。食管癌变率的频率差异为重度增生癌变率38．9％＞轻度增生癌变率5．8％＞正常癌变率1．4％。The carcinogenesis time and incidence of carcinoma of 46161 cases with normal, slight hyperplastic and severe hyperplastic esophageal epithelia were studied.The results indicated that the average time of esohpageal carcinogenesis in the cases with severe hyperplastic, slight hyperplastic and normal esophageal epithelia were 41, 64, and 106 months, respectively; The incidence of esophageal carcinoma in the cases with severe hyperplastic, slight hyperplastic and normal esophageal epithelia were 38. 9%, 5. 8%, 1. 4%, respectively.
