Aim: We evaluated the response to Trans-arterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) patients according to modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria. We determined the prognostic value of the neutrophil-to-lymphocyte ratio (NLR).

Background: TACE is the most commonly used method to treat patients with large, unresectable tumors or as bridge therapy in patients with HCC before liver transplantation.

Methods: In this cross-sectional study, patients with a diagnosis of HCC who were referred for TACE were studied. The response rate to TACE treatment was assessed based on dynamic MRI 28 days after treatment according to mRECIST criteria. The NLR value was calculated, and its prognostic value was evaluated to predict the response to treatment.

Results: Forty patients with HCC who underwent TACE were included. The response to TACE treatment included a complete response (CR) in 6 patients (15%), partial response (PR) in 16 patients (40%), and stable disease (SD) in 18 patients (45%). No progressive disease (PD) was found. Responders (CR and PR) were 22 patients (55%). The mean NLR after treatment in the non-responders was significantly higher than in the responders (4.2 vs. 2.4, P-value = 0.026). NLR values greater than 2.6 after treatment had a sensitivity of 70.6% and a specificity of 77.3% in diagnosing non-responders, with an Area Under the Curve (AUC) of 0.73 [95% confidence interval 0.58-0.89], P-value = 0.011.

Conclusion: Non-responders observed higher levels of NLR after treatment than responders. As a moderate prognostic factor, an NLR level of more than 2.6 after treatment could discriminate against non-responders.
