VEGF、Cath-D在喉复发癌组织芯片中的表达和意义

目的　研究VEGF、Cath D蛋白的表达与喉癌复发的关系 ,对预后进行估计。方法　回顾性分析 195 8～1999年喉癌手术病例 5 74例 ,术后随访 3年 ,确诊术后复发 5 6例 ;正常喉对照标本 39例。标本制成组织芯片 ,采用免疫组化SABC法对芯片标本进行染色。结果　VEGF、Cath D在喉癌组织中有表达 ,其阳性率不同。VEGF、Cath D蛋白的表达在喉癌复发组明显增强 ,与未复发组的表达差异有统计学意义 (P <0 0 0 1) ,与喉癌复发呈正相关。VEGF、Cath D蛋白在喉癌组织的表达与正常组织的表达比较差异有统计学意义 (P <0 0 0 1)。结论　VEGF、Cath D蛋白的表达可作为估计喉癌预后的指标

Significance of VEGF and Cath-D expressions in tissue arrays of patients with recurrent laryngeal carcinoma

Objective To evaluate the prognosis of recurrent laryngeal cancer after surgieat treatment, the study was designed to investigate the relationship of VEGF and Cath-D expression in patients with recurrent laryngeal carcinoma. Methods Five hundred and seventy-four cases of laryngeal carcinoma treated in our department from 1958 to 1999 were retrospectively reviewed. All patients were observed for 3 years postoperatively. The whole set of tissue microarrays prepared with tumor tissue from 574 patients, including recurrent tumor tissue from 56 patients, and also 39 normal laryngeal tissue from normal subjects. The tissue chips were analyzed by the SABC immunohistochemical method. Results VEGF and Cath-D were expressed in most of the laryngeal carcinoma and normal laryngeal tissue, but the positive ratio of them was different. There was higher expression of VEGF and Cath-D in recurrent laryngeal carcinoma compared with that in laryngeal carcinoma without recurrence and normal laryngeal tissue (P<0.001). There was positive correlation between the expression of VEGF and Cath-D with the recurrent laryngeal carcinoma. There was also significant difference between the laryngeal carcinoma and normal laryngeal tissue (P<0.001). Conclusion VEGF and Cath-D were the prognostic marker candidates for the postoperative recurrence of laryngeal cancer.
