摘要
目的基于18F-脱氧葡萄糖(FDG)标记的PET-CT分析非小细胞肺癌(NSCLC)患者压力相关神经活动(SNA)对主要心血管不良事件(MACE)的影响。方法回顾性收集2018—2019年东部战区总医院核医学科诊断为NSCLC并随访至少1年的患者资料。所有患者术前接受全身18F-FDG PET-CT及胸部CT检查。测量杏仁核最大靶-本底比值(TBR_(max))反映SNA、椎体骨髓TBR_(max)反映骨髓活性(BMA)并测量冠状动脉钙化体积及钙化积分(CACS)。以有无发生MACE进行分组,比较两组患者的基线临床信息、SNA、BMA及冠状动脉钙化情况。以杏仁核TBR_(max)中位数为界值,将患者分为低杏仁核TBR_(max)组与高杏仁核TBR_(max)组;依据CACS,将CACS=0者划分为无钙化灶,将CACS>0者划分为有钙化组。采用Kaplan-Meier法绘制生存曲线,log-rank检验比较不同组间MACE发生率的差异,多因素Cox比例风险回归模型分析MACE发生的相关因素。结果94例NSCLC患者年龄为(61.7±11.1)岁,男62例(66.0%)。MACE组患者13例(13.8%),无MACE组患者81例(86.2%)。MACE组杏仁核TBR_(max)、冠状动脉钙化体积和CACS均高于无MACE组(均P<0.05)。所有患者的随访时间为[M(Q 1,Q 3)]41(19,58)个月。高杏仁核TBR_(max)组MACE累积发生率高于低杏仁核TBR_(max)组(29.8%比2.6%,P=0.006),有钙化组MACE累积发生率高于无钙化组(39.9%比5.2%,P=0.010)。多因素Cox比例分析回归模型结果显示,与低杏仁核TBR_(max)组相比,高杏仁核TBR_(max)组发生MACE的风险增加(HR=11.832,95%CI:1.328~105.457,P=0.027);将杏仁核TBR_(max)与CACS相结合进行分组后,高杏仁核TBR_(max)+有钙化组发生MACE的风险较其余组增加(HR=18.613,95%CI:1.587~218.315,P=0.020)。结论NSCLC患者SNA与MACE发生相关,与低杏仁核TBR_(max)组相比,高杏仁核TBR_(max)组发生MACE的风险增加。
Objective To explore the associations between stress-related neural activity(SNA)and major adverse cardiovascular events(MACE)in non-small cell lung cancer(NSCLC)patients based on[18F]Fludeoxyglucose positron emission tomography-computed tomography(18F-FDG PET-CT).MethodsPatients with pathologically confirmed diagnosis of NSCLC and with at least one-year follow up were retrospectively collected in Nanjing Jinling Hospital between January 2018 and December 2019.All the patients undergoing 18F-FDG PET-CT and chest CT at baseline.The maximum target-to-background ratio(TBR_(max))values of amygdala,which represented as SNA,and bone marrow,which represented as bone marrow activity(BMA),coronary artery calcium volume and coronary artery calcium score(CACS)were measured.Patients were grouped according to presence or absence of MACE.The baseline clinical variable,SNA,BMA and CACS were compared between two groups.Patients were divided as low-and high-amygdala TBR_(max) groups according to the median of amygdala TBR_(max).According to the CACS,patients with CACS=0 were classified as non-calcification group,while those with CACS>0 are classified into the calcification group.The Kaplan-Meier analysis was used to plot survival curves,the log-rank test was employed to compare intergroup differences in MACE incidence and the Cox proportional hazards model was performed to analyze risk factors for MACE.ResultsA total of 94 NSCLC patients were included,aged(61.7±11.1)years and including 62 males(66.0%).There were 13 patients(13.8%)in the MACE goup and 81 patients(86.2%)in the non-MACE group.The amygdala TBR_(max),coronary artery calcium volume and CACS in the MACE group were higer than those in non-MACE group.The follow-up time was[M(Q 1,Q 3),41(19,58)]months.The cumulative incidence of MACE in the high-amygdala TBR_(max) group was higher than that in the low-amygdala TBR_(max) group(29.8%vs 2.6%,P=0.006).The cumulative incidence of MACE in the calcification group was higher than that in the noncalcification(39.9%vs 5.2%,P=0.010).Multivariate Cox regression analysis showed that compared with low-amygdala TBR_(max) group,the incidence rate of MACE increased in high-amygdala TBR_(max) group(HR adj=11.832,95%CI:1.328-105.457,P=0.027).Further,patients were grouped according to amygdala TBR_(max) combined with CACS,high-amygdala TBR_(max) with CACS>0 group had increased risk for MACE compared to the remaining groups(HR adj=18.613,95%CI:1.587-218.315,P=0.020).ConclusionsSNA was associated with the incidence of MACE in NSCLC patients.The incidence of MACE in high-amygdala TBR_(max) group was higher than that in low-amygdala TBR_(max) group.
