ABSTRACT:
Background
Methods
Utilizing the University of Pittsburgh Medical Center (UPMC) electronic health records, we created a retrospective cohort of 27,834 patients diagnosed with NAFLD from 2004 to 2018 with complete NLR data. After an average 5.5 years of follow-up, 203 patients developed HCC. Cox proportional hazard regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) of HCC incidence associated with different levels of NLR and lymphocyte count.
Results
Compared with the lowest tertile of NLR (<1.97), the highest tertile of NLR (≥3.09) was statistically significantly associated with a 43% higher risk of HCC incidence (HR = 1.43, 95% CI: 1.01–2.03, ptrend = 0.031) after adjustment for age, sex, race, body mass index, smoking status, history of type 2 diabetes, hyperlipidemia, hypertension, and fibrosis-4 score category. Conversely the highest tertile of lymphocyte count (≥2.15 K/ul) was significantly associated with a 36% lower risk of HCC (HR = 0.64, 95% CI: 0.43–0.94, ptrend = 0.028) compared to the lowest tertile (<1.55 K/ul). There was no association between neutrophil count and HCC risk.
Conclusions
Higher NLR and lower lymphocyte count are associated with significantly higher risk of HCC among NAFLD patients. These findings warrant further investigation of immune response and surveillance in association with HCC development in NAFLD patients.
