Prospective Collection of Therapeutic Efficacy and Safety Data in Patients with Unresectable Hepatocellular Carcinoma

The malignant degree of middle and advanced liver cancer is very high, and the survival prognosis of patients is very poor. TACE is currently the standard treatment for unresectable liver cancer recommended by several international authoritative guidelines. However, TACE can only extend survival from 8 months to 13 months, and the prognosis for patients with unresectable liver cancer is still not optimistic. In recent years, some studies have suggested that the combination of TACE and systemic therapy can prolong OS and PFS, but a number of prospective studies have found that the combination of TACE and targeted therapy can not improve the prognosis of unresectable liver cancer. However, TACE as a non-radical treatment is difficult to achieve complete tumor necrosis, so it is still unknown which treatment combination can best improve the prognosis. This trial is an observational clinical trial to explore the efficacy and safety of TACE combined targeting/immunotherapy for unresectable hepatocellular carcinoma. Clinical data of patients with unresectable liver cancer treated in our hospital from March 2023 to March 2025 are intended to be collected to evaluate the efficacy and safety of TACE combined with different systems for unresectable liver cancer.
