Association Between Adjuvant Sorafenib and the Prognosis of Patients With Hepatocellular Carcinoma at a High Risk of Recurrence After Radical Resection
Abstract
BackgroundThe use of sorafenib in the adjuvant management of hepatocellular carcinoma (HCC) is controversial.AimTo analyze the effects of adjuvant sorafenib therapy in patients with HCC at high recurrence risk after radical resection.MethodsThis was a retrospective study of patients who underwent radical resection (R0 resection) for HCC at the Cancer Hospital of Tianjin Medical University between August 2009 and August 2017. All patients had microvascular invasion and were evaluated for portal vein tumor thrombus. The outcomes were overall survival (OS), recurrence-free survival (RFS), and survival after recurrence. Propensity score matching (PSM) was used.ResultsBefore matching, there were 56 and 167 patients in the sorafenib and non-sorafenib groups. After PSM, there were 42 patients/group, and there were no significant differences in patient characteristics (all P>0.05). After PSM, compared with the non-sorafenib group, the sorafenib group showed longer median OS (34 vs. 26 months, P=0.032) and survival after recurrence (16 vs. 9 months, P=0.002), but no difference in RFS (14 vs. 11 months, P=0.564). Adjuvant sorafenib was the only factor independently associated with OS (HR=0.619, 95% CI: 0377–0.994, P=0.047). No factors were independently associated with RFS (all P>0.05).ConclusionAlthough adjuvant sorafenib therapy for patients with HCC and high recurrence risk does not reduce the recurrence risk of HCC, it might be associated with longer survival and a lower risk of death.
