Introduction:Sorafenib was the first therapy used for systemic treatment of unresectable hepatocellular carcinoma (HCC). Multiple prognosis factors associated with sorafenib therapy have been described. Objectives:The aim of this work was to evaluate survival and time to progression (TTP) on HCC patients treated with sorafenib, and check for predictive factors of sorafenib benefit. Materials and Methods:Retrospectively, data from all HCC patients treated with sorafenib in a Liver Unit from 2008 to 2018 were collected and analyzed. Results:Sixty-eight patients were included; 80.9% were male, the median age was 64.5 years, 57.4% had Child-Pugh A cirrhosis and 77.9% were BCLC stage C. Macrovascular invasion (MVI) was present in 25% of the patients and 25% of the subjects had other extrahepatic metastasis. The median survival was 10 months (IQR 6.0–14.8) and median TTP was 5 months (IQR 2.0–7.0). Survival and TTP were similar between Child-Pugh A and B patients: 11.0 months (IQR 6.0–18.0) for Child-Pugh A and 9.0 months (IQR 5.0–14.0) for Child-Pugh B (p= 0.336). In univariate analysis, larger lesion size (LS >5 cm), higher alpha-fetoprotein (AFP >50 ng/mL), and no history of locoregional therapy were statistically associated with mortality (HR 2.17, 95% CI 1.24–3.81; HR 3.49, 95% CI 1.90–6.42; HR 0.54, 95% CI 0.32–0.93, respectively), but only LS and AFP were independent predictive factors, as shown in multivariate analysis (LS: HR 2.08, 95% CI 1.10–3.96; AFP: HR 3.13, 95% CI 1.59–6.16). MVI and LS >5 cm were associated with TTP shorter than 5 months in univariate analysis (MVI: HR 2.80, 95% CI 1.47–5.35; LS: HR 2.1, 95% CI 1.08–4.11), but only MVI was an independent predictive factor of TTP shorter than 5 months (HR 3.42, 95% CI 1.72–6.81). Regarding safety data, 76.5% of patients reported at least one side effect (any grade), and 19.1% presented grade III–IV adverse effects leading to treatment discontinuation. Conclusions:We observed no significant difference in survival or TTP in Child-Pugh A or Child-Pugh B patients treated with sorafenib, as compared to more recent real-life studies. Lower primary LS and AFP were associated with a better outcome, and lower AFP was the main predictor of survival. The reality of systemic treatment for advanced HCC has recently changed and continues to evolve, but sorafenib remains a viable therapeutic option.
