Abstract
Fluorine-18 fluorodeoxyglucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) has some limitations in diagnosis of Intrahepatic cholangiocarcinoma (ICC). Patients with histologically confirmed ICC who underwent both [18F]FDG and 18F-labeled fibroblast-activation protein inhibitors ([18F]FAPI)-04 PET/CT were prospectively analyzed. The maximum standard uptake value (SUVmax), tumor-to-background ratio (TBR), metabolic tumor volume (MTV), total lesion glycolysis (TLG), [18F]FAPI–avid tumor volume (FTV), total lesion fibroblast activation protein expression (TLF) were compared between the two modalities by paired Wilcoxon signed-rank test and Mann–Whitney U test, and McNemar’s test was used to assess the diagnostic accuracy between the two techniques. In total, 23 patients with 389 lesions were included. Compared to [18F]FDG, [18F]F-FAPI-04 PET/CT demonstrated a higher detection rate for intrahepatic lesions (86.3% vs. 78.2% P = 0.040), lymph node metastases (85.2% vs. 68.2%, P = 0.007), peritoneal metastases (100% vs. 93.8%), and bone metastases (100% vs. 70.5%, P < 0.001). [18F]FAPI-04 PET showed higher SUVmax, TBR and greater tumor burden values than [18F]FDG PET in non-cholangitis intrahepatic lesions (SUVmax: 8.7 vs. 6.4, P < 0.001; TBR: 8.0 vs. 3.5, P < 0.001; FTV vs. MTV: 41.3 vs. 12.4, P < 0.001; TLF vs. TLG: 223.5 vs. 57.0, P < 0.001), lymph node metastases (SUVmax: 6.5 vs. 5.5, P = 0.042; TBR: 5.4 vs. 3.9, P < 0.001; FTV vs. MTV: 2.0 vs. 1.5, P = 0.026; TLF vs. TLG: 9.0 vs. 7.8 P = 0.024), and bone metastases (SUVmax: 9.7 vs. 5.25, P < 0.001; TBR: 10.8 vs. 3.0, P < 0.001; TLF vs. TLG: 9.8 vs. 4.2, P < 0.001). However, [18F]FDG showed higher radiotracer uptake (SUVmax: 14.7 vs. 8.4, P < 0.001; TBR: 7.4 vs. 2.8, P < 0.001) than [18F]FAPI-04 PET/CT for 6 patients with obstructive cholangitis. [18F]FAPI-04 PET/CT yielded a change in planned therapy in 6 of 23 (26.1%) patients compared with [18F]FDG. [18F]FAPI-04 PET/CT had higher detection rate and radiotracer uptake than [18F]FDG PET/CT in intrahepatic lesions, lymph node metastases, and distant metastases, especially in bone. Therefore, [18F]FAPI-04 PET/CT may be a promising technique for diagnosis and staging of ICC. Clinical Trials, NCT05485792.

氟-18脱氧葡萄糖([18F]FDG)正电子发射断层扫描/计算机断层扫描(PET/CT)在诊断肝内胆管癌(ICC)方面存在一些局限性。我们对同时接受[18F]FDG和18F标记成纤维细胞活化蛋白抑制剂([18F]FAPI)-04 PET/CT检查的组织学确诊ICC患者进行了前瞻性分析。通过配对 Wilcoxon 符号秩检验和 Mann-Whitney U 检验比较了两种方法的最大标准摄取值(SUVmax)、肿瘤与背景比(TBR)、代谢肿瘤体积(MTV)、总病灶糖酵解(TLG)、[18F]FAPI-avid 肿瘤体积(FTV)、总病灶成纤维细胞活化蛋白表达(TLF),并用 McNemar 检验评估了两种技术的诊断准确性。共纳入了 23 名患者的 389 个病灶。与[18F]FDG相比,[18F]F-FAPI-04 PET/CT对肝内病变(86.3% 对 78.2%,P = 0.040)、淋巴结转移(85.2% 对 68.2%,P = 0.007)、腹膜转移(100% 对 93.8%)和骨转移(100% 对 70.5%,P < 0.001)的检出率更高。在非胆管炎肝内病变中,[18F]FAPI-04 PET显示出比[18F]FDG PET更高的SUVmax、TBR和更大的肿瘤负荷值(SUVmax:8.7 vs. 6.4,P <0.001;TBR:8.0 vs. 3.5,P <0.001;FTV vs. MTV:41.3 vs. 12.4,P <0.001):41.3 vs. 12.4,P < 0.001;TLF vs. TLG:223.5 vs. 57.0,P < 0.001)、淋巴结转移(SUVmax:6.5 vs. 5.5,P = 0.042;TBR:5.4 vs. 3.9,P < 0.001;FTV vs. MTV:2.0 vs. 1.5, P = 0.026; TLF vs. TLG: 9.0 vs. 7.8 P = 0.024)和骨转移(SUVmax:9.7 vs. 5.25, P < 0.001; TBR: 10.8 vs. 3.0, P < 0.001; TLF vs. TLG: 9.8 vs. 4.2, P < 0.001)。然而,在6例阻塞性胆管炎患者中,[18F]FDG的放射性示踪剂摄取量(SUVmax:14.7 vs. 8.4,P < 0.001;TBR:7.4 vs. 2.8,P < 0.001)高于[18F]FAPI-04 PET/CT。与[18F]FDG相比,[18F]FAPI-04 PET/CT 使 23 例患者中的 6 例(26.1%)改变了治疗计划。与[18F]FDG PET/CT 相比,[18F]FAPI-04 PET/CT 对肝内病灶、淋巴结转移和远处转移(尤其是骨转移)的检出率和放射性示踪剂摄取率更高。因此,[18F]FAPI-04 PET/CT 可能是一种很有前途的 ICC 诊断和分期技术。临床试验,NCT05485792。2022年8月1日注册,回顾性注册,https//clinicaltrials.gov/study/NCT05485792?cond=NCT05485792&rank=1。
