BACKGROUND
The aim of this study was to investigate the influence of CDK5 regulatory subunit-associated protein 1-like 1 (CDKAL1) expression on the survival of nasopharyngeal carcinoma (NPC) patients.
METHODS
A total of 140 non-metastatic NPC patients were retrospectively analyzed. The expression of CDKAL1 was detected by immunohistochemistry.
RESULTS
The CDKAL1-negative group exhibited better overall survival (OS) according to Kaplan-Meier curve analysis ( = 0.006), with 5-year OS rates for the CDKAL1-negative and -positive groups of 89.7% and 70.2%, respectively. The CDKAL1-negative group also exhibited a tendency toward a better progression-free survival (PFS) rate. Multivariate analysis showed that CDKAL1 expression was independently associated with both OS ( = 0.002) and PFS ( = 0.043).
CONCLUSION
CDKAL1 expression is an independent negative predictor of patient survival in non-metastatic NPC.
背景
本研究旨在探讨细胞周期蛋白依赖性激酶5调节亚基相关蛋白1样蛋白1（CDKAL1）表达对鼻咽癌（NPC）患者生存的影响。
方法
回顾性分析140例非转移性NPC患者。采用免疫组织化学法检测CDKAL1的表达。
结果
根据Kaplan-Meier曲线分析，CDKAL1阴性组的总生存期（OS）较好（P = 0.006），CDKAL1阴性组和阳性组的5年OS率分别为89.7%和70.2%。CDKAL1阴性组的无进展生存期（PFS）率也有更好的趋势。多因素分析显示，CDKAL1表达与OS（P = 0.002）和PFS（P = 0.043）均独立相关。
结论
CDKAL1表达是非转移性NPC患者生存的独立负性预测指标。
