Prognostic evaluation value of 18F-FDG PET/MR metabolic and diffusion parameters in non-small cell lung cancer patients
目的 探讨18F-氟代脱氧葡萄糖(18F-fluorodeoxyglucose,18F-FDG)正电子发射断层扫描/磁共振(positron emission tomography/magnetic resonance,PET/MR)成像代谢参数及扩散参数对非小细胞肺癌(non-small cell lung cancer,NSCLC)患者预后评估的价值.材料与方法 前瞻性纳入CT检查怀疑有肺部占位性病变后进行3.0 T胸部18F-FDG PET/MR混合扫描的患者48例,分析扫描图像的最大标准摄取值(maximum standardized uptake value,SUVmax)和表观扩散系数(apparent diffusion coefficient,ADC)与临床可能预后因素的关系.用Kaplan-Meier法、Log-rank检验及单因素和多因素Cox回归分析代谢参数SUVmax和ADC与无进展生存期(progression-free survival,PFS)和总生存期(overall survival,OS)的关系.结果 48例NSCLC患者的SUVmax和ADC的中位数分别为5.87(3.92,9.66)和1.41(1.28,1.57).单因素分析显示,是否手术[HR=6.704,95%置信区间(confidence interval,CI)为1.422~31.614,P=0.016;HR=7.174,95%CI为1.486~34.626,P=0.014]、SUVmax(HR=1.170,95%CI为1.010~1.355,P=0.036;HR=1.173,95%CI为1.010~1.360,P=0.035)及ADC(HR=0.010,95%CI为0.000~0.232,P=0.004;HR=0.006,95%CI为0.000~0.156,P=0.002)是NSCLC患者PFS和OS的影响因素.多因素分析显示,ADC(HR=0.012,95%CI为0.000~0.386,P=0.012;HR=0.008,95%CI为0.000~0.298,P=0.009)是影响NSCLC患者PFS和OS的独立危险因素.结论 SUVmax和ADC都是NSCLC患者预后的影响因素,并且,ADC可能比SUVmax更有助于预测NSCLC患者的预后,18F-FDG PET/MR代谢参数及扩散参数对NSCLC患者预后评估具有一定的价值.
Objective:To investigate the value of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography magnetic resonance (PET/MR) metabolic parameters and diffusion parameters in the prognosis of patients with non-small cell lung cancer (NSCLC). Materials and Methods:Prospective 3.0 T chest 18F-FDG PET/MR hybrid scans were performed in patients suspected of having lung space occupying lesions by CT examination in Henan Provincial People's Hospital from July 8,2020 to July 29,2021. The relationship between the maximum standardized uptake value (SUVmax) and apparent diffusion coefficient (ADC) of scanned images and clinical possible prognostic factors was analyzed. Kaplan Meier method,log rank test and univariate and multivariate Cox regression were used to analyze the relationship between metabolic parameter SUVmax and diffusion parameter ADC and overall survival (OS) and progression free survival (PFS). Results:The median SUVmax and ADC of 48 NSCLC patients were 5.87 (3.92,9.66) and 1.41 (1.28,1.57),respectively. Univariate analysis showed that whether surgery[HR=6.704,95% confidence interval (CI):1.422-31.614,P=0.016;HR=7.174,95% CI:1.486-34.626,P=0.014],SUVmax (HR=1.170,95% CI:1.010-1.355,P=0.036;HR=1.173,95% CI:1.010-1.360,P=0.035) and ADC (HR=0.010,95% CI:0.000-0.232,P=0.004;HR=0.006,95% CI:0. 000-0.156,P=0.002) were the influencing factors of PFS and OS in NSCLC patients. Multivariate analysis showed that ADC (HR=0.012,95% CI:0.000-0.386,P=0.012;HR=0.008,95% CI:0.000-0.298,P=0.009) was an independent risk factor for PFS and OS in NSCLC patients. Conclusions:Both SUVmax and ADC are prognostic factors for NSCLC patients,and ADC may be more helpful in predicting the prognosis of NSCLC patients than SUVmax. 18F-FDG PET/MR metabolic parameters and diffusion parameters have certain value for the prognosis evaluation of NSCLC patients.
