Microwave ablation combined with transarterial chemoembolization containing doxorubicin hydrochloride liposome for treating primary and metastatic liver cancers

Aims: To determine the safety and efficacy of microwave ablation（MWA） and transarterial chemoembolization（TACE） with doxorubicin hydrochloride liposome（DHL） in patients with primary liver cancer（PLC） and metastatic liver cancer（MLC）.Materials and methods: The medical records of patients with primary or metastatic liver cancer who underwent MWA combined with TACE containing DHL from March 2019 to March 2022 were collected and analyzed.Treatment-related adverse events（AEs） were recorded. Local tumor response was evaluated according to the modified RECIST criteria. Local tumor progression-free survival（LTPFS） and overall survival（OS） were calculated using the Kaplan-Meier method.Results: Altogether, 96 patients with liver cancer were included（PLC, n = 45; MLC, n = 51）. Forty（41.7%） patients experienced AEs during treatment, and eight（8.3%） patients developed grade 3 AEs. Compared to before treatment, the serum total bilirubin level and neutrophil to lymphocyte ratio significantly increased after treatment. The median LTPFS was 14.5 months in patients with PLC and 10.7 months in patients with MLC. The median OS was not reached in patients with PLC or MLC. The 1-month and 3-month disease control rates reached more than 80% in both groups.Conclusion: MWA combined with TACE with DHL may be a safe and effective method for the treatment of liver cancer.
