摘要:

目的 探讨根治性放化疗(D-CRT)前18F-FDG PET/CT代谢和异质性参数结合临床特征对食管鳞状细胞癌(ESCC)患者预后的预测价值。 方法 回顾性分析接受D-CRT的106例ESCC患者的临床资料,所有患者在治疗前均接受了18F-FDG PET/CT检查,通过数据处理获得肿瘤原发灶的代谢和异质性参数。随访所有患者的总生存期。采用Kaplan-Meier法和Cox比例风险模型分析患者临床特征、肿瘤代谢和异质性参数与患者预后的关系。 结果 所有患者1、1.5年总生存率分别为77.4%、51.9%,中位生存时间为20个月。单因素分析表明:N分期、M分期、肿瘤代谢体积、病灶糖酵解总量、异质性指数-2(HI-2)、40%最大标准化摄取值为阈值的变异系数(CV40%)与ESCC预后相关(P < 0.05)。多因素分析表明:N分期、CV40%是ESCC患者预后的独立危险因素(P = 0.039、 < 0.001)。 结论 N分期、肿瘤代谢异质性参数CV40%与ESCC D-CRT患者的预后密切相关,并具有一定的预测价值。

Abstract:

Objective This study aimed to explore the prognostic value of 18F?FDG PET/CT Metabolic and Heterogeneity Parameters Combined with Clinical Features Before Definitive Chemoradiotherapy (D?CRT) in predicting the prognosis of esophageal squamous cell carcinoma (ESCC) Patients. Methods A retrospective analysis was conducted on clinical data from 106 patients with ESCC who received D?CRT at the first affiliated Hospital of University of Science and Technology of China between January 2017 and December 2021. All patients underwent 18F?FDG PET/CT examination before the treatment. The primary tumor's metabolic and heterogeneity parameters were obtained through data processing. All patients were followed up for overall survival. The Kaplan?Meier method and Cox proportional hazards models were used to analyze the association between clinical features, tumor metabolism and heterogeneity parameters and patient prognosis. Results The 1? and 1.5?year overall survival rates of all patients were 77.4%and 51.9%. The median survival time was 20 months. Univariate analysis showed that N stage, M stage, metabolic tumor volume, total lesion glycolysis, heterogeneity index?2 (HI?2), and coefficient of variation with a threshold of 40% maximum standard uptake value (CV40%) were correlated with the prognosis of ESCC (all P< 0.05). Multivariate analysis showed that N stage and CV40% were independent predictors of prognosis in patients with ESCC (P = 0.039 and P < 0.001, respectively). Conclusion N stage and tumor metabolic heterogeneity parameter CV40%, which offering a degree of predictive value, are closely related to the prognosis of patients with ESCC treated with D?CRT.
