Abstract

Malignant tumors in cholangiocarcinoma are diagnosed and staged using 18F‑fluorodeoxyglucose positron emission tomography (FDG‑PET) and clinical analysis. However, comprehensive analysis, including pathological analysis, has not yet been sufficiently performed. In the present study, the maximum standardized uptake value (SUVmax) was calculated using FDG‑PET and its relationship with clinicopathological factors was analyzed. The present study included 86 patients who underwent preoperative FDG‑PET/computed tomography (CT) and did not receive chemotherapy among 331 patients with hilar and distal cholangiocarcinoma. Receiver operating characteristic analysis with recurrence events was used to determine the SUVmax cutoff of 4.9. Immunohistochemical staining of glucose transporter 1 (Glut1), hypoxia‑inducible factor‑1α and Ki‑67 was performed for pathological analysis. The standardized uptake value (SUV)‑high group (SUVmax ≥4.9) had a higher postoperative recurrence rate (P<0.046) and higher Glut1 and Ki‑67 expression rates (P<0.05 and P<0.0001, respectively). Furthermore, SUVmax and Glut1 expression (r=0.298; P<0.01) and SUVmax and Ki‑67 expression rates (r=0.527; P<0.0001) were positively correlated. The preoperative measurement of SUVmax by PET‑CT is useful in predicting recurrence as well as cancer malignancy.
