目的 研究喉癌手术的安全切缘距离与癌肿原发部位的关系 ,获取声门上型喉癌和声门型喉癌的安全切缘的定量数据。方法 于癌肿周围 ,以条、纵向连续切片方法 ,对 33例喉癌手术切除标本进行显微测量。结果 发现喉癌声门上型和声门型局部的侵袭方式和程度均不相同。 95 %的声门上型喉癌显微镜下侵袭距离 <10 5 2mm ,而 95 %的声门型喉癌侵袭距离 <4 41mm。结论 喉癌的局部侵袭存在着明显的位置依从性。
Objective To study the relationship between the safety margins of primary laryngeal carcinoma and the primary site of cancer and to obtain the quantitative data of the safety margin of supraglottic carcinoma and glottic laryngeal carcinoma. Methods Thirty-three cases of laryngeal cancer were examined by microscopy in the vicinity of the cancer with serial and longitudinal sections. The results showed that the supraglottic and glottic laryngeal invasion of local methods and levels are not the same. 95% of the supraglottic laryngeal carcinoma under the microscope invasion distance <1052mm, while 95% of the glottic laryngeal cancer invasion <41mm. Conclusion The local invasion of laryngeal carcinoma has obvious location compliance.
