: Cholangiocarcinoma (CCA) is a diverse group of fatal malignancies arising from the biliary tract. Surgical resection with negative margin offers the only potentially curative option. The majority of patients present at locally advanced or metastatic stages, when surgical resection is not feasible, highlighting the significance of systemic therapy. Given the limited effectiveness of traditional chemotherapy regimens in CCA, many investigators have focused on developing novel molecular therapies targeting key aberrant signaling pathways.: We present the main genomic aberrations known to play a key role in cholangiocarcinogenesis and discuss promising targeted therapies in clinical development.In October of 2020, a review of the English literature was performed utilizing PubMed and Web of Science databases for the keywords of 'cholangiocarcinoma', 'biliary tract cancer', and 'targeted therapy'.: Unfortunately, despite encouraging results in preclinical studies, the outcome of clinical trials with established targeted therapies like anti-EGFR medications have been discouraging. Currently, agents targeting FGFR2 fusion and IDH1/2 mutations hold great promise for improving the management of CCA. Future studies focused on enhancing our understanding of key aberrant signaling pathways of cholangiocarcinogenesis and the design of homogeneous and biomarker-driven cohorts are key elements of establishing precision medicine in CCA.
胆管癌(CCA)是一组源自胆道的致命恶性肿瘤,具有异质性。阴性切缘的手术切除是唯一潜在的治愈选择。大多数患者在局部晚期或转移性阶段出现,此时手术切除不可行,这凸显了系统治疗的重要性。鉴于传统化疗方案在 CCA 中的有限疗效,许多研究人员专注于开发针对关键异常信号通路的新型分子疗法。
我们介绍了已知在胆管癌发生中起关键作用的主要基因组异常,并讨论了临床开发中具有前景的靶向治疗药物。
不幸的是,尽管在临床前研究中取得了令人鼓舞的结果,但已确立的靶向治疗药物(如抗 EGFR 药物)的临床试验结果令人沮丧。目前,针对 FGFR2 融合和 IDH1/2 突变的药物为改善 CCA 的治疗提供了巨大希望。未来的研究侧重于深入了解胆管癌发生的关键异常信号通路,并设计同质且基于生物标志物的队列,这是在 CCA 中建立精准医学的关键要素。
