68Ga-FAPI PET在胆道癌中的前瞻性评估 (FAPi-2)
FAP 2:镓-68-成纤维细胞激活蛋白抑制剂(FAPI)PET在胆道癌中的效用:一项前瞻性研究
这项前瞻性观察性研究旨在评估镓-68成纤维细胞活化蛋白抑制剂(FAPI)PET/CT是否能够改善对疑似或确诊胆道癌(包括胆囊癌、胆管癌)以及治疗后疑似复发成年患者(≥18岁)的检测、分期和复发评估。
本研究旨在回答的主要问题是:
与标准FDG PET/CT相比,FAPI PET/CT是否能为原发肿瘤、淋巴结病变和转移灶提供更高的敏感性、特异性和诊断准确性?
FAPI PET/CT是否能提供额外的诊断价值,可能影响临床决策和分期,从而潜在地减少侵入性分期程序的需求?
研究人员将比较FAPI PET/CT与FDG PET/CT,以观察FAPI是否能提高对转移性或复发性疾病(特别是腹膜或肝转移以及淋巴结受累)的检测能力。
参与者将:
提供书面知情同意。
接受FAPI PET/CT成像(基线时和/或疑似生化或影像学复发时)。
进行定量成像参数评估(SUVmax、肿瘤与肝脏比值、代谢体积)。
可能接受与FDG PET/CT和/或作为金标准的随访影像学或组织病理学比较。
研究概览
详细说明
胆道癌症通常在中晚期才被发现,需要精确分期以指导治疗决策,如手术、系统治疗或姑息治疗。尽管18F-FDG PET/CT在临床实践中广泛应用,但其在检测小原发病灶、淋巴结转移、肝转移和腹膜癌变方面的诊断性能有限。镓-68成纤维细胞活化蛋白抑制剂(FAPI)PET/CT是一种新型成像技术,靶向癌症相关的成纤维细胞,这些细胞在胆道癌症特征性的纤维增生性基质中含量丰富。早期证据表明,与FDG PET/CT相比,FAPI PET/CT可能提供更好的病灶检测能力和肿瘤与背景对比度。
这项前瞻性观察研究将评估Ga-68 FAPI PET/CT在胆道癌症患者初始分期和疑似复发中的临床应用。将评估诊断性能指标(敏感性、特异性、阳性预测值、阴性预测值,以及半定量PET参数如SUVmax和代谢体积),并与作为金标准的FDG PET/CT和/或随访成像或组织病理学进行比较。该研究旨在确定FAPI PET/CT的增量诊断贡献及其对临床决策的潜在影响。
这项研究的发现可能有助于定义FAPI PET/CT作为胆道癌症分期和再分期的补充或替代成像方式的作用,并可能支持未来的前瞻性多中心试验。
