目的探讨氨基酸正电子发射断层扫描(PET)示踪剂L-3-[18 F]-氟-α-甲基酪氨酸(FAMT)对[18 F]-氟脱氧葡萄糖(FDG)诊断恶性肿瘤的补充作用。我们比较了预测能力的FAMT PET与FDG PET转移性口腔鳞状细胞癌(OSCC)的结果为远处转移,包括淋巴结转移,并确定了相关的代谢参数为each.MethodsWe招募了160例OSCC患者进行PET/计算机断层扫描使用FDG和FAMT治疗前。使用临床病理学特征,如标准化摄取值(SUVmax,SUVpeak),代谢肿瘤体积(MTV)和总病变糖酵解或总病变保留来评估结局。单变量和多变量考克斯比例风险模型被用来确定无病生存期(DFS)和总生存期(OS)的独立预测因子,平均随访时间分别为1401.7和1646.0天。受试者工作特征曲线下的面积分析的准确性和预测价值的成像参数。多变量分析显示,浸润性生长模式[p= 0.034,风险比(HR)= 2.30]和FDG测量的SUV峰值与OS显著相关。(p= 0.045,HR = 2.45)是DFS的独立危险因素,淋巴结转移是DFS的独立危险因素,(p= 0.03,HR = 2.57)和FAMT测量的MTV(p= 0.004,HR = 3.65)是OS的独立危险因素。结论在OSCC患者中,FDG PET预测DFS,而FAMT预测OS。与临床参数相结合,为OSCC提供补充的、与结果相关的诊断信息。
ObjectivesL-3-[18F]-Fluoro-α-methyl tyrosine (FAMT), an amino acid positron emission tomography (PET) tracer, complements [18F]-fluorodeoxyglucose (FDG) in the diagnosis of malignancies. We compared the predictive ability of FAMT PET versus FDG PET regarding metastatic oral squamous cell carcinoma (OSCC) outcomes for distant metastasis, including lymph node metastasis, and identified the relevant metabolic parameters for each.MethodsWe enrolled 160 patients with OSCC who underwent PET/computed tomography using FDG and FAMT before treatment. Outcomes were assessed using clinicopathological characteristics such as the standardized uptake value (SUVmax, SUVpeak), metabolic tumor volume (MTV), and total lesion glycolysis or total lesion retention. Univariate and multivariate Cox proportional hazards models were used to identify the independent predictors of disease-free survival (DFS) and overall survival (OS) during an average follow-up time of 1401.7 and 1646.0 days, respectively. Areas under the receiver operating characteristic curves were analyzed for the accuracy and predictive value of imaging parameters.ResultsClinical parameters (excluding age) and PET metabolic parameters were significantly associated with OS. Multivariate analysis showed that an infiltrative growth pattern [p= 0.034, hazard ratio (HR) = 2.30], and the FDG-measured SUVpeak(p= 0.045, HR = 2.45) were independent risk factors for DFS and that lymph node metastasis (p= 0.03, HR = 2.57) and the FAMT-measured MTV (p= 0.004, HR = 3.65) were independent risk factors for OS.ConclusionsIn patients with OSCC, FDG PET predicted DFS, whereas FAMT predicted OS. The two PET tracers, combined with clinical parameters, provide complementary, outcome-related diagnostic information in OSCC.
