Serum proteomic profiling identifies pathways and protein signatures associated with early versus late recurrence in cholangiocarcinoma
Cholangiocarcinoma (CCA) is characterized by frequent postoperative recurrence, yet reliable biomarkers for distinguishing early from late recurrence remain limited. This study aimed to identify serum protein biomarkers associated with early versus late recurrence and develop a proteomic recurrence score (PRS) to disti...
