喉鳞状细胞癌组织朗格罕斯细胞浸润及其临床意义

目的 观察喉鳞状细胞癌组织中朗格罕斯细胞(LC)浸润情况,探讨其临床意义.方法 选取喉鳞状细胞癌患者72例,均经手术切除肿瘤组织.采用免疫组织化学SP法检测喉鳞状细胞癌组织中LC浸润情况,分析LC浸润程度与肿瘤分期、复发、转移及预后等的关系.结果 72例喉鳞状细胞癌患者中LC浸润程度为"+"共27例(37.5%),"++"共27例(37.5%),"+++"共18例(25.0%).喉癌组织LC浸润程度与患者颈部淋巴结转移、复发、无病生存期、3年生存率及5年生存率均相关(P＜0.05),与年龄、分型、TNM分期、术后放疗均无关(P>0.05).结论 喉鳞状细胞癌患者的肿瘤组织中均可见LC浸润,LC浸润程度越高,提示患者预后越好.

Langerhans cell infiltration in laryngeal squamous cell carcinoma and its clinical significance

Objective To observe the infiltration situation of Langerhans cells(LC)in laryngeal squamous cell carcinoma tissue and to investigate its clinical significance.Methods Seventy-two cases of laryngeal squamous cell carcinoma were selected and the tumor tissue in all cases was operatively resected.The immunohistochemical SP method was adopted to detect the infiltration situation of LC in laryngeal squamous cell carcinoma tissue.Then the relationship between the LC infiltration degree with tumor stage,relapse,metastasis and prognosis was analyzed.Results Among 72 cases of laryngeal squamous cell carcinoma,27 cases(37.5％)were LC infiltration degree of "+",37 cases(37.5％)were "++" and 18 cases(25.0％)were "+++".The LC infiltration degree in laryngeal carcinoma tissue was correlated with the cervical lymph node metastasis,recurrence,disease free survival,3-year survival and 5-year survival(P＜0.05),and had no correlation with the age,classification,TNM stage and postoperative radiotherapy(P>0.05).Conclusion LC infiltration can be seen in the tumor tissue of the patients with laryngeal squamous cell carcinoma.The LC infiltration degree is higher,indicating that the prognosis would be better.
