Early and accurate diagnosis remains the cornerstone of successful BTC treatment. Noninvasive biomarkers, particularly liquid biopsy platforms, hold promise for improving detection and monitoring. Clinically, the establishment of high-volume BTC centers with integrated scientific and medical expertise is essential to translate molecular analyses into personalized therapies. Moreover, systematic incorporation of BTC-related clinical and molecular data into international multicenter trials is imperative. Such integration will refine therapeutic paradigms, accelerate drug development, and foster innovation through strategic collaborations with pharmaceutical industry consortia.
