Abstract

Background

The ARQ197-215 study randomized patients (pts) to tivantinib or placebo and pre-specified efficacy analyses indicated the predictive value of MET expression as a marker of benefit from tivantinib for second-line treatment of hepatocellular carcinoma (HCC). The aim of the current analysis was to evaluate in the ARQ197-215 cohort the neutrophil-to-lymphocyte ratio (NLR), which is thought to be a prognostic factor associated with clinical outcomes in several solid tumours.

Methods

A post hoc exploratory analysis was carried out on 98 ARQ197-215 pts with available absolute neutrophil count and absolute lymphocyte count, and preserved liver function. The cut-off used to define a high versus low NLR was the predefined value of 3.0, which corresponds to the median value. The effect of NLR was estimated with respect to overall survival (OS) and time to progression (TTP).

Results

No association was detected between the NLR and other known prognostic factors, including portal vein thrombosis (p = 0.671), MET expression (p = 0.552), alpha-fetoprotein levels (p = 0.837), and distant metastases (p = 0.521). In univariate analysis, compared with low NLR, a high NLR was associated with a hazard ratio (HR) for OS of 1.58 [95% confidence interval: 1.01; 2.47; p = 0.046]. Also, in multivariate analysis, the NLR and portal vein thrombosis remained independent prognostic factors for OS within the entire cohort. Median OS was 7.8 months versus 5.1 months for patients with NLR

Conclusions

Baseline NLR is a readily available and inexpensive prognostic biomarker in pts with advanced/metastatic HCC who are candidate for second-line treatments. This effect was independent of other known prognostic factors.
