Background
There is conflicting evidence concerning platelet status and hepatocellular carcinoma (HCC) prognosis. We evaluated the prognostic value of platelet-based indices, including platelet count, platelet/lymphocyte ratio (PLR), and aspartate aminotransferase to platelet ratio index (APRI) in HCC after hepatic resection.
Methods
We retrospectively reviewed 332 patients with HCC treated with hepatectomy between 2006 and 2009. Preoperative platelet count, as well as demographic, clinical, and pathologic data, were analyzed.
Results
Both disease-free survival (DFS) and overall survival (OS) were significantly improved for patients with low platelet count, PLR, and APRI compared to patients with elevated values. On multivariate analysis, APRI, tumor size ≥5 cm, noncapsulation, and multiple tumors were all associated with both poor DFS and OS. The 1-, 3-, and 5-year DFS rates were 52, 36, and 32 % for patients with APRI <0.62 and were 35, 22, and 19 % for patients with APRI ≥0.62. Correspondingly, the 1-, 3-, and 5-year OS rates were 77, 51, and 42, and 63, 35, and 29 % for both groups. Both DFS and OS of patients with APRI <0.62 were significantly better compared to patients with an elevated APRI (P = 0.009 and 0.002, respectively). Patients with elevated APRI tended to have cirrhosis, hepatitis B virus (HBV) infection, surgical margin <1 cm, and noncapsulated tumors.
Conclusions
Elevated platelets based inflammatory indices, especially APRI, was associated with adverse characteristic features and poor prognosis in HCC, especially for patients with HBV infection or cirrhosis. Antiplatelet treatment may represent a potential therapy for HBV-induced HCC recurrence.
