Accumulating data indicate that clinically available abdominal imaging tests such as EUS and MRI/MRCP can detect asymptomatic precursor benign (IPMN, PanIN) and invasive malignant pancreatic neoplasms, such as ductal adenocarcinoma, in individuals with an inherited predisposition. These asymptomatic FPCs detected have been more likely to be resectable, compared to symptomatic tumors. The most challenging part of screening high-risk individuals is the selection of individuals with high-grade precursor neoplasms for preventive treatment (ie, surgical resection before development of invasive cancer). Ongoing and future research should focus on formulating and validating a model for FPC risk and neoplastic progression using patient characteristics, imaging, and biomarkers. The comparative cost and effectiveness of various approaches for screening and surveillance of high-risk individuals also deserves study. For now, screening is best performed in high-risk individuals within the research protocols in academic centers with multidisciplinary teams with expertise in genetics, gastroenterology, radiology, surgery, and pathology.
越来越多的数据表明,临床上可用的腹部影像学检查,如 EUS 和 MRI/MRCP,可检测出具有遗传易感性的个体中无症状的前体良性(IPMN、PanIN)和侵袭性恶性胰腺肿瘤,如导管腺癌。与有症状的肿瘤相比,这些检测到的无症状的 FPC 更有可能是可切除的。筛查高危人群最具挑战性的部分是选择具有高级别前体肿瘤的个体进行预防性治疗(即在侵袭性癌症发生前进行手术切除)。正在进行和未来的研究应侧重于使用患者特征、影像学和生物标志物来制定和验证 FPC 风险和肿瘤进展的模型。筛查和监测高危人群的各种方法的成本和效果比较也值得研究。目前,最好在具有遗传学、胃肠病学、放射学、外科学和病理学专业知识的多学科团队的学术中心的研究方案中,对高危人群进行筛查。
