1. If patients with active hepatitis B undergo correct and aggressive antiviral treatment, it can reduce inflammation, decrease the activity of virus and improve the survival rate. Active and correct antiviral treatment for patients after hepatocellular carcinoma surgery can reduce tumor recurrence and improve prognosis. On the one hand, it can directly inhibit tumor growth by inhibiting RAF/MEK/ERK signaling pathway; on the other hand, it can indirectly inhibit tumor cell growth by blocking the formation of tumor neovascularization through inhibiting VEGFR and PDGFR, which has significant efficacy on advanced kidney cancer and liver cancer On the other hand, it can block tumor neovascularization by inhibiting VEGFR and PDGFR and indirectly inhibit tumor cell growth.
