摘要: 本研究探讨氟代脱氧葡萄糖正电子发射计算机断层显像/计算机断层显像(18F-FDG PET/CT)技术评价2型糖尿病(T2DM)对晚期结直肠癌患者程序性死亡受体-1配体(PD-L1)治疗疗效的影响,选取104例晚期结直肠癌患者,根据是否伴有T2DM分为T2DM组(n=49)、无T2DM组(n=55)。比较两组疗效及18F-FDG PET/CT技术参数:平均标准摄取值(SUVmean)、最大标准摄取值(SUVmax)、代谢体积(MTV)、病灶糖酵解总量(TLG),探讨18F-FDG PET/CT的应用价值。结果显示,T2DM组病理分期、疗效、SUVmean、SUVmax、MTV、TLG与无T2DM组比较,差异有统计学意义(P<0.05);T2DM组、无T2DM组未缓解者SUVmean、SUVmax、MTV、TLG均高于缓解者(P<0.05);T2DM组缓解者SUVmean、SUVmax、MTV、TLG高于无T2DM组缓解者(P<0.05);SUVmean、SUVmax、MTV、TLG与疗效呈负相关(P<0.05);SUVmean、SUVmax、MTV联合TLG预测T2DM未缓解的价值最高。采用18F-FDG PET/CT技术联合检测SUVmean、SUVmax、MTV、TLG能评价T2DM对晚期结直肠癌患者PD-L1靶向治疗疗效的影响,并能客观、量化预测患者的治疗反应性。

Abstract: This study explored the evaluation of 18F-fluorodeoxyglucose positron emission computed tomography/computed tomography (18F-FDG PET/CT) technology for the evaluation of type 2 diabetes (T2DM) on the programmed death receptor-1 ligand in patients with advanced colorectal cancer (PD-L1) The effect of treatment efficacy. A total of 104 patients with advanced colorectal cancer were selected, and they were divided into T2DM group (n=49) and no T2DM group (n=55) according to whether they were accompanied by T2DM. The efficacy and 18F-FDG PET/CT technical parameters:average standard uptake value (SUVmean), maximum standard uptake value (SUVmax), metabolic volume (MTV), total glycolysis of lesions (TLG) were 237 compared between the two groups, and the application value of 18F-FDG PET/CT were explored. The results showed that the pathological staging, curative effect, SUVmean, SUVmax, MTV, TLG of the T2DM group were compared with those without T2DM, and the difference was statistically significant (P<0.05); T2DM and T2DM without remission were SUVmean, SUVmax, MTV, TLG SUVmean, SUVmax, MTV, and TLG in the T2DM group were higher than those in the non-T2DM group (P<0.05). SUVmean, SUVmax, MTV, and TLG were negatively correlated with the efficacy (P<0.05). SUVmean, SUVmax, MTV combined with TLG predict the highest value of T2DM unrelief. The combined detection of SUVmean, SUVmax, MTV, and TLG with 18F-FDG PET/CT technology can evaluate the effect of T2DM on the efficacy of PD-L1 targeted therapy in patients with advanced colorectal cancer, and can objectively and quantitatively predict the patient’s response to treatment.
