The platelet-to-lymphocyte ratio predicts poor survival in patients with huge hepatocellular carcinoma that received transarterial chemoembolization

Inflammation is particularly strong in huge hepatocellular carcinoma (HCC). However, it is unclear whether the platelet-to-lymphocyte ratio (PLR), as an inflammatory-related marker, can predict survival of patients with huge HCC. In this study, we enrolled 291 patients with huge HCC (diameter over 10 cm) who were undergoing repeated transarterial chemoembolization (TACE) at our institute. The baseline PLR was calculated from complete serum blood counts before the first chemoembolization. We found that a baseline PLR cutoff value over 150 best predicted huge HCC survival. The 12, 24, and 36 months survival rates in the high PLR group (22.6, 8.1, and 4.1 %, respectively) were significantly lower than in the low PLR group (35.6, 22.4, and 14 %, respectively). Thus, a significant difference was found in overall survival (log–rank test, p < 0.0001). Univariate analyses indicated a high PLR (p < 0.0001) was predictor of poor survival, and multivariate Cox analyses further showed that a high PLR (p = 0.002) was an independent factor that predicted worse survival. In conclusion, for patients with huge HCC, a high baseline PLR is a useful predictor of poor survival in patients undergoing chemoembolization. Additional anti-inflammatory or anti-platelet treatments, in combination with TACE, may improve survival in HCC patients with high PLR.
