Abstract
Objective: To investigate the efficacy and safety of drug-eluting beads transcatheter arterial chemoembolization(DEB-TACE) combined with systemic chemotherapy and immune checkpoint inhibitors in the treatment of unresectable intrahepatic cholangiocarcinoma.
Methods: This study used retrospective cohort analysis to collect the clinical data of 209 patients with unresectable intrahepatic cholangiocarcinoma treated in Linyi Cancer Hospital, Affiliated Zhongshan Hospital of Dalian University, Affiliated Central Hospital of Dalian University of Technology from January 2020 to January 2024. The patients were divided into observation group and control group based on their treatment plans. The observation group was treated with DEB-TACE combined with systemic chemotherapy and immune checkpoint inhibitor, and the control group was treated with simple systemic chemotherapy and immune checkpoint inhibitor. Based on propensity score matching analysis, the clinical treatment efficacy, survival prognosis, and incidence of adverse reactions of two groups of patients were evaluated.
Results: 82 patients in the observation group received DEB-TACE combined with systemic chemotherapy and immune checkpoint inhibitors, The control group of 127 patients were treated with systemic chemotherapy and immune checkpoint inhibitors. After a propensity score matching analysis to control for the consistency of patient age, sex, tumor size, tumor number, Child grade, ECOG score, and tumor stage. Propensity score matching analysis created 71 pairs of patients in 2 groups. The objective response rate (ORR, 76.06%) and disease control rate (DCR, 97.18%) in the observed group were significantly higher than that in the control group (52.11%, 85.92%), Progression-free survival (PFS, 10 months) and overall survival (OS, 17 months) were higher than the control group (8 months, 11 months). The Cox proportional hazards model analysis revealed that, Child grade and treatment modality were independent predictors of PFS and OS in patients. The adverse effects during treatment were similar in the two groups, with no statistical difference.
Conclusions: Compared with systemic therapy alone (systemic chemotherapy + immune checkpoint inhibitor), combined DEB-TACE improves the tumor control rate of patients with unresectable intrahepatic cholangiocarcinoma, extends the survival time and without increasing treatment-related adverse effects, which is a safe and feasible treatment modality.
期刊介绍：
World Journal of Surgical Oncology publishes articles related to surgical oncology and its allied subjects, such as epidemiology, cancer research, biomarkers, prevention, pathology, radiology, cancer treatment, clinical trials, multimodality treatment and molecular biology. Emphasis is placed on original research articles. The journal also publishes significant clinical case reports, as well as balanced and timely reviews on selected topics.
Oncology is a multidisciplinary super-speciality of which surgical oncology forms an integral component, especially with solid tumors. Surgical oncologists around the world are involved in research extending from detecting the mechanisms underlying the causation of cancer, to its treatment and prevention. The role of a surgical oncologist extends across the whole continuum of care. With continued developments in diagnosis and treatment, the role of a surgical oncologist is ever-changing. Hence, World Journal of Surgical Oncology aims to keep readers abreast with latest developments that will ultimately influence the work of surgical oncologists.
