Screening, prevention and diagnosis

SubgroupSettingApproachProducts and trialsEvidence
All comersDiagnosis and stagingContrast CT/MRI with MRCP; ERCP or EUS-guided biopsy; molecular profiling (DNA + RNA NGS) for all advanced disease; biliary drainage if jaundiced.75

Early / localised

SubgroupSettingApproachProducts and trialsEvidence
All comersResectableSurgery + adjuvant capecitabine.
All comersResectableMargin-negative resection (hepatectomy, Whipple, or radical cholecystectomy) with lymphadenectomy; adjuvant capecitabine 6 months (BILCAP).69

Advanced, first line

SubgroupSettingApproachProducts and trialsEvidence
All comersAdvancedGem-cis + PD-(L)1; targeted therapy by genotype second line.98
All comersUnresectable perihilar in selected patientsNeoadjuvant chemoradiation then liver transplantation (Mayo protocol) at experienced centres.40
All comersAdvanced, first lineGemcitabine-cisplatin + durvalumab (TOPAZ-1) or + pembrolizumab (KEYNOTE-966); zanidatamab added in HER2+ disease within HERIZON-BTC-302.98
All comersAdvanced, other alterationsZenocutuzumab (NRG1 fusion, approved 2026); dabrafenib-trametinib (BRAF V600E); pembrolizumab or dostarlimab (MSI-H/dMMR); larotrectinib/entrectinib (NTRK).98

Second line

SubgroupSettingApproachProducts and trialsEvidence
All comersSecond-line, no targetFOLFOX (ABC-06, modest benefit); liposomal irinotecan/5-FU had conflicting results (NIFTY positive, NALIRICC negative); clinical trials preferred.93
FGFRAdvanced, FGFR2 fusion after chemotherapyPemigatinib or futibatinib; tinengotinib in FIRST-308 after progression.67
HER2Advanced, HER2-positive after chemotherapyZanidatamab (IHC 3+ or amplified); trastuzumab deruxtecan (IHC 3+, tumour-agnostic).97
IDHAdvanced, IDH1 mutation after chemotherapyIvosidenib (ClarIDHy).89

Other settings

SubgroupSettingApproachProducts and trialsEvidence
All comersLocoregional (intrahepatic, liver-confined)Y-90 radioembolisation, hepatic arterial infusion pump chemotherapy, or SBRT at specialised centres; no phase 3 proof of survival benefit.40

Lines and subgroups are parsed from the setting text of each standard-of-care row and can misclassify an unusual phrasing; the row’s own setting is always shown. Guideline chips reflect the NCCN category and ESMO-MCBS grade recorded on the cancer page, checked on its stated date. Not medical advice.
