GGTLC1 and intrahepatic cholangiocarcinoma: Patients diagnosed with ICC and exhibiting COX-2 (+) demonstrated elevated gamma-glutamyl transpeptidase-to-platelet ratio (0.43 [0.23, 1.08] vs 0.22 [0.13, 0.47], P = .002), increased aspartate aminotransferase-to-platelet ratio index (0.38 [0.19, 0.75] vs 0.26 [0.20, 0.39], P = .033), and higher platelet-to-lymphocyte ratio (139.2 [106.8, 174.5] vs 124.2 [80.6, 164.8], P = .033) (Table 5).
