Abstract:Objective To investigate the clinical efficacy and adverse reactions of pirarubicin-loaded microspheres combined with lobaplatin in interventional embolization therapy for primary liver cancer.Methods A total of 92 patients with advanced primary liver cancer admitted to the First Affiliated Hospital of Hebei North University between June 2020 and June 2022 were selected in this study. Patients were assigned into the control group (n=46) and observation group (n=46) according to the random number table method. All patients were treated with interventional embolization. Patients in control group were treated by perfusion of lobaplatin, and those in observation group were treated with pirarubicin-loaded microspheres on the basis of the control group. The efficacy and the occurrence of adverse reactions were compared between the two groups, as well as the levels of vascular endothelial growth factor (VEGF), osteopontin (OPN), tumor necrosis factor-α (TNF-α), total bilirubin (TBil), and alanine transaminase (ALT).Results The total effective rate of the observation group (84.78%) was obviously higher than that of the control group (65.22%) (P<0.05). Compared with before treatment, the levels of VEGF, OPN, TNF-α, TBil, and ALT in the two groups were obviously reduced after treatment (P<0.05). After treatment, the levels of VEGF, OPN, TNF-α, TBil, and ALT in the observation group were obviously reduced when compared with the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the observation group and the control group (P>0.05).Conclusion The combination of pirarubicin-loaded microspheres and lobaplatin showed a good effect in the interventional embolization therapy of primary liver cancer. It can improve the disease control rate and liver function of patients.
