［目的］分析食管癌Ｘ线分型与放疗疗效的关系。［方法］１９９３年５月至１９９７年１２月对６１例食管癌患者分为５型：蕈伞型、髓质型、溃疡型、缩窄型及腔内型。采用６０Ｃｏ或 ６ＭＶ～８ＭＶ Ｘ线进行单纯放疗，放疗总剂量６０００ｃＧｙ～７０００ｃＧｙ。［结果］蕈伞型、髓质型、溃疡型、缩窄型及腔内型的有效率分别为 ９２．７％、８７．１％、３０．０％、１６．０％、０。全组总有效率为６８．９％。［结论］蕈伞型和髓质型明显优于溃疡型、缩窄型及腔内型（Ｐ＜０．０１）。
[Objective] To analyze the relationship between X-ray classification and radiotherapy efficacy in esophageal cancer. [Methods] From May 1993 to December 1997, 61 cases of esophageal cancer patients were divided into 5 types: umbrella-type, medulla-type, ulcer-type, constriction-type and intraluminal type. Radiotherapy with 60Co or 6MV to 8MV X-rays was performed. The total dose of radiation therapy was 6000 cGy to 7000 cGy. [Results] The effective rates of Umbrella, Medullary, Ulcer, Constricted, and Intracavity were 92.7%, 87.1%, 30.0%, 16.0%, and 0, respectively. The total effective rate for the whole group was 68.9%. [Conclusion] Umbrella type and medulla type were significantly better than those of ulcer type, constriction type and intraluminal type (P<0.01).
