Cholangiocarcinoma (CCA) is an aggressive malignancy arising from the biliary epithelium. It may occur at any location along the biliary tree with the perihilar area being the most common. Prognosis is poor with 5-year overall survival at less than 10%, typically due to unresectable disease at presentation. Radical surgical resection with clear margins offers a chance of cure in patients with resectable tumours, but is frequently not possible due to locally advanced disease. On the other hand, orthotopic liver transplantation (LT) allows for a radical and potentially curative resection for these patients, but has been historically controversial due to the limited supply of donor grafts and previously poor outcomes. In patients with perihilar CCA, within specific criteria and following the implementation of a protocol combining neoadjuvant chemoradiation and LT, excellent results have been achieved in the last decades, resulting in its increasing acceptance as an indication for LT and the standard of care in several centres with significant experience. However, in intrahepatic CCA, the role of LT remains controversial and owing to dismal previous results it is not an accepted indication. Nevertheless, more recent studies have demonstrated favourable results with LT in early intrahepatic CCA, indicating that, under defined criteria, its role may increase in the future. This review highlights the history and contemporary advances of LT in CCA, with particular focus on the improving outcomes of LT in intrahepatic and perihilar CCA and future perspectives.
胆管癌(CCA)是一种起源于胆管上皮的侵袭性恶性肿瘤。它可能发生在胆管树的任何部位,其中肝门周围区域最为常见。由于患者就诊时常处于不可切除的疾病状态,总体预后较差,5 年总生存率不到 10%。根治性手术切除且切缘无肿瘤残留可使可切除肿瘤患者获得治愈机会,但由于局部晚期疾病,通常无法实现。另一方面,对于这些患者,原位肝移植(LT)可进行根治性且有潜在治愈机会的切除,但由于供体移植物的有限供应以及先前较差的结果,在历史上一直存在争议。在肝门周围 CCA 患者中,在符合特定标准并实施联合新辅助放化疗和 LT 的方案后,近几十年来取得了优异的结果,使其越来越多地被接受为 LT 的适应证,并成为具有丰富经验的多个中心的治疗标准。然而,在肝内 CCA 中,LT 的作用仍存在争议,由于先前结果不佳,其并非被接受的适应证。然而,最近的研究表明,LT 在早期肝内 CCA 中具有良好的效果,表明在明确的标准下,其作用可能在未来会增加。这篇综述强调了 LT 在 CCA 中的历史和当代进展,特别关注 LT 在肝内和肝门周围 CCA 中改善预后的作用,以及未来的展望。
