These subtypes exhibit significant molecular, genetic, and histopathological differences that impact patient prognosis and treatment responsiveness. This review advocates for a subtype-specific approach to iCCA research and clinical management, including tailored therapeutic strategies that consider distinct genetic profiles and tumor microenvironments. Current therapeutic approaches hold promise, yet efficacy varies by subtype. Additionally, subtype-specific molecular diagnostics, including DNA methylation-based classifiers and transcriptomic sequencing, have shown potential in refining iCCA subclassification, thereby guiding precision medicine efforts. This article outlines existing clinical trials, key research trajectories, and future directions for developing more effective subtype-adapted therapies for iCCA. 000298945 536__ $$0G:(DE-HGF)POF4-311$$a311 - Zellbiologie und Tumorbiologie (POF4-311)$$cPOF4-311$$fPOF IV$$x0 000298945 588__ $$aDataset connected to CrossRef, PubMed, , Journals: inrepo02.dkfz.de 000298945 650_7 $$2Other$$aclinical trial 000298945 650_7 $$2Other$$aintrahepatic cholangiocarcinoma 000298945 650_7 $$2Other$$amolecular targeted therapy 000298945 650_7 $$2Other$$amutation 000298945 650_7 $$2Other$$asurvival 000298945 650_7 $$2Other$$atranslational research 000298945 7001_ $$0P:(DE-He78)0116f5652cc0dbf455e3aa3914740230$$aZhu, Lei$$b1$$eFirst author$$udkfz 000298945 7001_ $$0P:(DE-He78)27fb0d2bd2832c8c977e636025736942$$aTao, Jianxin$$b2$$udkfz 000298945 7001_ $$aReißfelder, Christoph$$b3 000298945 7001_ $$0P:(DE-He78)a9d57fe3333789705a9ceb9ca904e83e$$aSchölch, Sebastian$$b4$$eLast author$$udkfz 000298945 773__ $$0PERI:(DE-600)2155736-6$$a10.1016/j.molmed.2025.01.008$$gp.
