［摘 要］ 目的：探讨皮肤 T 细胞淋巴瘤相关抗原 15（cutaneous T cell lymphoma associated antigen 15，CTAGE15）在食管鳞状
细胞癌（esophageal squamous cell carcinoma，ESCC）中的表达与患者临床预后的关系及其对ESCC细胞增殖、迁移及侵袭等能力
的影响。方法：Kaplan⁃Meier分析公共数据库中CTAGE15与ESCC患者预后的关系。qRT⁃PCR检测正常食管上皮细胞、ESCC
细胞和临床120例随访信息完整的ESCC患者肿瘤组织及邻近正常组织中CTAGE15表达，COX生存风险分析方法研究ESCC
患者的生存风险因素，多变量相关性分析 CTAGE15 表达与 ESCC 患者临床病理之间的关系，同时采用 Kaplan⁃Meier 分析
CTAGE15对ESCC患者预后的影响。利用小干扰RNA沉默ESCC细胞中CTAGE15的表达，检测细胞增殖、迁移及侵袭能力的
变化。结果：公共数据库中CTAGE15表达水平与患者总生存期（P < 0.05）和疾病特异性生存期（P < 0.05）显著相关，GTAGE15
高表达患者生存期较好。qRT⁃PCR结果表明临床ESCC组织及ESCC细胞中CTAGE15表达显著高于正常食管上皮组织及正常
食管上皮细胞，且CTAGE15表达水平与ESCC患者T分期与N分期显著相关（P < 0.05），CTAGE15高表达患者T分期、N分期较

GTAGE15低表达患者早。敲低CTAGE15后，ESCC细胞的增殖、迁移及侵袭能力显著增强（P < 0.05）。结论：CTAGE15与ESCC
患者预后成正相关，且能够抑制ESCC细胞的增殖、迁移及侵袭等能力。

［Abstract］ Objective： To investigate the expression of cutaneous T cell lymphoma associated antigen 15（CTAGE15）and its
association with clinical prognosis of esophageal squamous cell carcinoma（ESCC）patients，as well as its effect on the proliferation，
migration，and invasion abilities of ESCC cells. Methods：Kaplan⁃Meier analysis was used to analyze the effect of CTAGE15 on the
prognosis of ESCC patients in public database. The mRNA expression levels of CTAGE15 in esophageal epithelial cells and ESCC
cells were measured by qRT⁃PCR. Furthermore，the expression of CTAGE15 was detected in cancer and adjacent normal tissues from
120 ESCC patients with a complete follow⁃up information. COX proportional survival risk model was enrolled to analyze the survival
risk factors of ESCC patients，and multivariate correlation analysis was used for the analysis of the association between CTAGE15
expression and the clinicopathology of ESCC patients. Kaplan⁃Meier analysis was employed to analyze the effect of CTAGE15 on the
prognosis of ESCC patients. The knockdown of CTAGE15 in ESCC cells was achieved by using small interfering RNA（siRNA），and
the changes in cell proliferation，migration，and invasion abilities of ESCC cells were assessed. Results：The public database showed
that the CTAGE15 expression was significantly associated with overall survival（P < 0.05）and disease⁃specific survival（P < 0.05）in
