Abstract
Abstract Background The aim of the study was to investigate the efficacy of continuous transcatheter arterial infusion chemotherapy combined with transarterial chemoembolization (TACE) for the treatment of advanced pancreatic cancer with liver metastasis. Methods Sixty patients with advanced pancreatic cancer and liver metastases were enrolled in this study. In the treatment group, 31 patients underwent continuous transcatheter arterial infusion chemotherapy combined with TACE regional arterial thermal perfusion, whereas 29 patients included in the control group received intravenous chemotherapy with gemcitabine and S-1. All patients received maintenance chemotherapy with S-1 after 4 cycles of the study regimen. Treatment efficacy, quality of life, survival, and toxicity were evaluated. Results Efficacy was better in the treatment group than in the control group, as reflected by the objective remission, partial remission, and disease progression rates (all P < 0.05). The Eastern Cooperative Oncology Group and Numerical Rating Scale pain scores were also higher in the treatment group (both P < 0.05). In survival analysis, the 1-year overall survival rates in the treatment and control groups were 64.516% and 10.345%, respectively, whereas the median overall survival times were 16 and 6 months, respectively (both P < 0.05). The 6-month progression-free survival rates in the treatment and control groups were 77.419% and 13.790%, respectively, and the median progression-free survival times were 12 and 3 months, respectively (both P < 0.05). The rates of hematological and nonhematological toxicological adverse effects were also lower in the treatment group (both P < 0.05). Although the rate of liver dysfunction was higher in the treatment group, this finding had no adverse effects on prognosis. Conclusions Continuous transcatheter arterial infusion chemotherapy combined with TACE regional arterial perfusion chemotherapy resulted in better efficacy and safety outcomes in patients with pancreatic cancer and liver metastasis, suggesting its utility as a reference method for the clinical treatment of advanced pancreatic cancer.
