Clinical Value of Platelet and Its Parameters Combined with Tumor Markers in Preoperative Differentiation of Hepatocellular Carcinoma and Intrahepatic Cholangiocarcinoma

Objective To evaluate the value of PLT and its parameters combined with AFP, CA199, CA125 and CEA on the preoperative differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). Methods We analyzed retrospectively 274 patients with liver cancer who underwent surgery in the Second Hospital of Lanzhou University. They were divided into 229 cases in HCC group and 45 cases in ICC group according to postoperative pathological results. The differences of PLT, its parameters and tumor markers between the two groups were compared. ROC curve was used to evaluate the differential diagnosis effect on HCC and ICC by significantly different indicators in single and combined forms. The best scheme was verified in the patients with determined and undetermined preoperative diagnosis. Results Compared with HCC group, the levels of PLT, PCT, CA199 and CA125 in ICC group were higher (P<0.05) and the level of AFP was lower (P<0.05). The diagnostic analysis results of ROC curve showed that in single test, the AUC of AFP for HCC diagnosis was the largest (0.827). The AUC of the combined groups was higher than the single groups of tumor markers; the AUC of the PCT+AFP+CA199+CA125 group was the highest in all combination groups, and AUC was 0.891. The verification of the best combination group showed that the AUC was 0.924 in the preoperative determined diagnosis group and 0.854 in the undetermined diagnosis group. Conclusion Tumor markers in combination with PLT and PCT can increase the preoperative differential diagnosis efficacy of HCC and ICC. The combination of PCT, AFP, CA199 and CA125 before operation is helpful to further determine the diagnosis and plan the operation scheme.
