The prognostic value of serum calcium levels in nasopharyngeal carcinoma (NPC) remains unknown. This study aimed to evaluate the prognostic value of serum calcium levels in patients with NPC.
A total of 2094 patients diagnosed with NPC between April 2009 and September 2012 were enrolled in this retrospective analysis. The median follow-up time was 96.3 months (range: 4.1-120.0 months). Univariate and multivariable Cox proportional hazards models were used to identify significant and independent prognostic predictors of overall survival (OS), disease-free survival (DFS), distant metastasis-free survival (DMFS), and relapse-free survival (RFS).
Overall, low serum calcium levels were detected in 1109/2094 (53.00%) patients and tended to be more frequently detected in older (<0.001) and female (=0.001) patients. Patients with low serum calcium levels had poorer OS (=0.011), DFS (=0.012) and DMFS (=0.004) than those with high serum calcium levels, but serum calcium levels had no significant effect on RFS (=0.376). In univariate and multivariable analyses, low serum calcium levels were a statistically significant and independent prognostic factor for OS, DFS, and DMFS but had no prognostic value for RFS.
Serum calcium levels can serve as a prognostic predictor and guide more individualized treatment for NPC patients.
血清钙水平在鼻咽癌(NPC)中的预后价值尚不清楚。本研究旨在评估血清钙水平在鼻咽癌患者中的预后价值。
本回顾性分析纳入了2009年4月至2012年9月期间诊断为NPC的2094例患者。中位随访时间为96.3个月(范围:4.1 - 120.0个月)。采用单因素和多因素Cox比例风险模型来确定总生存期(OS)、无病生存期(DFS)、无远处转移生存期(DMFS)和无复发生存期(RFS)的显著和独立预后预测因素。
总体而言,1109/2094(53.00%)例患者检测到低血清钙水平,且在老年患者(<0.001)和女性患者(=0.001)中更常检测到。血清钙水平低的患者的OS(=0.011)、DFS(=0.012)和DMFS(=0.004)均比血清钙水平高的患者差,但血清钙水平对RFS无显著影响(=0.376)。在单因素和多因素分析中,低血清钙水平是OS、DFS和DMFS的统计学显著且独立的预后因素,但对RFS无预后价值。
血清钙水平可作为NPC患者的预后预测指标,并指导更个体化的治疗。
