Recently, neutrophil‐to‐lymphocyte ratio (NLR), a marker of systemic inflammation that is associated with tumor‐associated macrophages (TAMs), was suggested to be a prognostic marker of HCC treated with RFA. Therefore, we evaluated predictive factors, including NLR, associated with recurrence after curative RFA.</jats:p></jats:sec><jats:sec><jats:title>Methods:</jats:title><jats:p>A total of 163 patients initially diagnosed with HCC and treated with RFA were enrolled. We retrospectively analyzed factors associated with recurrence and survival after RFA. Furthermore, TAMs were evaluated using surgically resected specimens.</jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p>Hepatitis C virus (HCV) infection was the most frequent cause of HCC in this population (111 cases, 68.1%), whereas hepatitis B virus (HBV) infection accounted for 26 cases (16.0%). Recurrence, mostly intrahepatic distant recurrence, was found in 101 cases (61.9%). Recurrence and posttreatment NLR were independent prognostic factors related to survival, and male sex, HCV infection, serum des‐<jats:italic>γ</jats:italic>‐carboxy prothrombin >  40 AU/L, and posttreatment NLR were associated with recurrence. Pretreatment NLR showed no association with recurrence, whereas posttreatment NLR showed prognostic value. Interestingly, pretreatment NLR >  2.5 was significantly associated with recurrence in HBV‐HCC patients (odds ratio 3.439, <jats:italic>P</jats:italic> = 0.037) not but HCV‐HCC (odds ratio 1.430, <jats:italic>P</jats:italic> = 0.17).
