BACKGROUND Transcatheter arterial chemoembolization (TACE) is the main treatment for patients with primary hepatocellular carcinoma (PHC) who miss the opportunity to undergo surgery. Conventional TACE (c-TACE) uses iodized oil as an embolic agent, which is easily washed by blood and affects its efficacy. Drug-eluting bead TACE (DEB-TACE) can sustainably release chemotherapeutic drugs and has a long embolization time. However, the clinical characteristics of patients before the two types of interventional therapies may differ, possibly affecting the conclusion. Only a few studies have compared these two interventions using propensity-score matching (PSM). AIM To analyze the clinical effects of DEB-TACE and c-TACE on patients with PHC based on PSM. METHODS Patients with PHC admitted to Dangyang People’s Hospital (March 2020 to March 2024) were retrospectively enrolled and categorized into groups A (DEB-TACE, n = 125) and B (c-TACE, n = 106). Sex, age, Child-Pugh grade, tumor-node-metastasis stage, and Eastern Cooperative Oncology Group score were selected for 1:1 PSM. Eighty-six patients each were included post-matching. Clinical efficacy, liver function indices (aspartate aminotransferase, alanine aminotransferase, total bilirubin, and albumin), tumor serum markers, and adverse reactions were compared between the groups. RESULTS The objective response and disease control rates were significantly higher in group A (80.23% and 97.67%, respectively) than in group B (60.47% and 87.21%, respectively) (P < 0.05). Post-treatment levels of aspartate aminotransferase, alanine aminotransferase, and total bilirubin were lower in group A than in group B (P < 0.05), whereas post-treatment levels of albumin in group A were comparable to those in group B (P > 0.05). Post-treatment levels of tumor serum markers were significantly lower in group A than in group B (P < 0.05). Patients in groups A and B had mild-to-moderate fever and vomiting symptoms, which improved with conservative treatment. The total incidence of adverse reactions was significantly higher in group B (22.09%) than in group A (6.97%) (P < 0.05). CONCLUSION DEB-TACE has obvious therapeutic effects on patients with PHC. It can improve liver function indices and tumor markers of patients without increasing the rate of liver toxicity or adverse reactions.
