横断面影像学的应用越来越多,导致胰腺偶发性囊性病变的检出率越来越高。浆液性囊腺瘤(SCA)是良性囊肿,除非有症状,否则不需要手术干预。不幸的是,多达一半的SCA没有典型的影像学表现(“非典型SCA”),与潜在的恶性前驱病变重叠,从而构成诊断挑战。我们测试了使用数字EV筛查技术(DEST)分析循环细胞外囊泡(EV)生物标志物是否可以增强对胰腺囊性病变的鉴别,并避免对这些非典型SCA进行不必要的手术干预。对来自68名患者的血浆EV中的25种不同蛋白质生物标志物的分析鉴定了Das-1、波形蛋白、嗜铬粒蛋白A和CAIX的推定生物标志物特征,其具有高区分能力(AUC为0.99)。因此,分析血浆EV的多重标志物可能有助于临床决策。
Increased use of cross-sectional imaging has resulted in frequent detection of incidental cystic pancreatic lesions. Serous cystadenomas (SCAs) are benign cysts that do not require surgical intervention unless symptomatic. Unfortunately, up to half of SCAs do not have typical imaging findings (“atypical SCAs”), overlap with potentially malignant precursor lesions, and thus pose a diagnostic challenge. We tested whether the analysis of circulating extracellular vesicle (EV) biomarkers using a digital EV screening technology (DEST) could enhance the discrimination of cystic pancreatic lesions and avoid unnecessary surgical intervention in these atypical SCAs. Analysis of 25 different protein biomarkers in plasma EV from 68 patients identified a putative biomarker signature of Das-1, Vimentin, Chromogranin A, and CAIX with high discriminatory power (AUC of 0.99). Analysis of plasma EV for multiplexed markers may thus be helpful in clinical decision-making.
