Recurrence after curative resection of hepatic alveolar echinococcosis remains a clinical challenge. The current study tested if assessment of anti-recEm18 allows for postsurgical patient surveillance.
A retrospective study with patients undergoing liver resection for alveolar echinococcosis (n = 88) at the University Hospital Bern from 2002 to 2020 and at the University Hospital and Medical Center Ulm from 2011 to 2017 was performed. Analysis was directed to determine a potential association of pre- and postoperative values of anti-recEm18 with clinical outcomes.
Anti-recEm18 had a linear correlation to the maximum lesion diameter (R = 0.558). Three trajectories of anti-recEm18 were identified based on a threshold of 10 AU/ml: "Em18-low" (n = 31), "responders" (n = 53) and "residual disease" (n = 4). The decline of anti-recEm18 in "responders" reached a plateau after 10.9 months at which levels decreased by 90%. The only patient with recurrence in the entire population was also the only patient with a secondary increase of anti-recEm18.
In patients with preoperative elevated values, anti-recEm18 confirms curative surgery at 12 months follow-up and allows for long-term surveillance.
肝泡型包虫病（alveolar echinococcosis，AE）根治性切除术后的复发仍然是一个临床挑战。本研究旨在检验抗 recEm18 评估是否可用于术后患者监测。
对 2002 年至 2020 年在伯尔尼大学医院和 2011 年至 2017 年在乌尔姆大学医院和医疗中心接受肝切除术治疗 AE 的患者进行回顾性研究（n=88）。分析旨在确定术前和术后抗 recEm18 值与临床结局之间的潜在关联。
抗 recEm18 与最大病变直径呈线性相关（R=0.558）。根据 10 AU/ml 的阈值，确定了抗 recEm18 的三种轨迹：“Em18-低”（n=31）、“应答者”（n=53）和“残留疾病”（n=4）。“应答者”的抗 recEm18 下降在 10.9 个月后达到平台，水平下降 90%。在整个研究人群中唯一复发的患者也是唯一抗 recEm18 二次升高的患者。
在术前升高值的患者中，抗 recEm18 在 12 个月随访时可确认根治性手术，并可进行长期监测。
