The purpose of this study was to investigate better radiological prognostic factors in clinical T1 pure-solid non-small cell lung cancer (NSCLC).
This study enrolled 284 patients with clinical T1 solid NSCLC who underwent anatomical lung resection. The Cox proportional hazard model was used to evaluate the prognostic impact of tumor volume doubling time (VDT) at disease-free survival (DFS) and cancer-specific survival (CSS).
The median VDT was 347 days. Age (hazard ratio (HR) = 1.04; 95% confidence interval (CI), 1.01-1.07) and standardized uptake value max (SUVmax) (>6.0) (HR = 2.61; 95% CI, 1.52-4.66) were identified as significantly independent worse prognostic factors for DFS in a multivariable analysis without VDT. Furthermore, a multivariable analysis without SUVmax identified age (HR = 1.06; 95% CI, 1.03-1.09), CEA (>5.0 ng/ml) (HR = 2.34; 95% CI, 1.30-4.02), tumor diameter on CT (>2.0 cm) (HR = 1.91; 95% CI, 1.18-3.13), and VDT (HR = 4.03; 95% CI, 2.41-6.93) as significantly independent worse prognostic factors for DFS.
The VDT value could be a useful prognostic factor in clinical T1 solid NSCLC.
本研究旨在探讨临床 T1 纯实性非小细胞肺癌(NSCLC)中更好的影像学预后因素。
本研究纳入了 284 例接受解剖性肺切除术的临床 T1 实性 NSCLC 患者。采用 Cox 比例风险模型评估肿瘤倍增时间(VDT)在无病生存(DFS)和癌症特异性生存(CSS)方面的预后影响。
中位 VDT 为 347 天。年龄(风险比(HR)=1.04;95%置信区间(CI),1.01-1.07)和最大标准摄取值(SUVmax)(>6.0)(HR=2.61;95%CI,1.52-4.66)是多变量分析中DFS 的独立不良预后因素,而不包括 VDT。此外,在不包括 SUVmax 的多变量分析中,年龄(HR=1.06;95%CI,1.03-1.09)、癌胚抗原(CEA)(>5.0ng/ml)(HR=2.34;95%CI,1.30-4.02)、CT 上肿瘤直径(>2.0cm)(HR=1.91;95%CI,1.18-3.13)和 VDT(HR=4.03;95%CI,2.41-6.93)是 DFS 的独立不良预后因素。
VDT 值可能是临床 T1 实性 NSCLC 的一个有用的预后因素。
