作者对95例食管初期癌(103个病变)X线所见作了回顾性研究,手术时癌浸润深度在粘膜下层以内者为初期癌,其中癌浸润在粘膜上皮内者(ep-癌)22例,28个病变。浸润不超过粘膜肌层者(mm-癌)14例,15个病变。浸润达粘膜下层者(sm-癌)59例、60个病变。ep癌多为1 cm以下小病变,sm癌多为7 cm以上大病变,2～6 cm的病灶只按病变大小难以判定其浸润程度。ep癌X线所见为颗粒状。mm癌呈边缘轻度伸展不良或不规整,有时见双重轮廓。sm癌边缘不规整。从癌的浸润深度和时间关系可得如下结论:ep癌从发育异常到癌化时间为1年7个月～3年2个月,从ep癌到sm癌时
The authors retrospectively studied 95 cases of early esophageal cancer (103 lesions) with X-ray findings. The depth of invasion of the tumor in the submucosa during surgery was primary cancer, and the cancer infiltrated in the mucosal epithelium (ep-cancerous)22 Cases, 28 lesions. Infiltration of no more than mucosal muscularis (mm- cancer) in 14 cases, 15 lesions. Infiltrates submucosa (sm-cancer) in 59 cases and 60 lesions. Ep cancer is mostly small lesions less than 1 cm, sm cancer is more than 7 cm large lesions, 2 to 6 cm lesions based on the size of the lesion is difficult to determine the degree of infiltration. Ep cancer X-ray seen as granular. Carcinomas are mildly malextensive or irregular at margins, sometimes with double contours. Sm cancer edge irregular. From the relationship between the depth of invasion and the time of cancer, the following conclusions can be drawn: The time from dysplasia to cancerization of ep cancer is 1 year 7 months to 3 years 2 months, from ep to sm cancer
