Hepatocellular carcinoma (HCC) is the 6th most common malignant tumor, and it ranks 3rd in terms of cancer-related deaths, with an overall survival rate of 3-5% (1). Unfortunately, its incidence is still rising around the world (2). Hepatitis viral infections and alcoholism are the dominant factors that trigger HCC. Diabetes, obesity, and metabolic disorders are also associated with HCC (3). Common treatments include resection, ablation, chemoembolization, radiotherapy, and chemotherapy (4). The preferred approach, surgical resection can increase the 5-year survival rate to 60% (5). However, most patients exhibit nonspecific clinical symptoms, so when the condition is ultimately diagnosed they are unable to undergo radical surgery (6). Only 10-15% of patients with HCC are eligible for surgical resection. As a downstaging therapy, transcatheter arterial chemoembolization (TACE) has been widely used to treat unresectable HCC, and it can improve the overall survival of patients with HCC (7,8). Summary Transcatheter arterial chemoembolization (TACE) plays an important role in the treatment of unresectable liver cancer. We conducted this meta-analysis to compare the clinical safety and efficacy of conventional TACE (C-TACE) and drug-eluting beads (DEB)-TACE. A search for those procedures was performed using the PubMed, EMBASE, and Cochrane Library databases. A meta-analysis of patients who underwent C-TACE or DEB-TACE was conducted. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Of 334 studies, 30 were analyzed. The complete response rate, disease control rate, objective response rate, 3-year survival rate, and non-response rate were significantly higher in patients who underwent DEB-TACE than those in patients who underwent C-TACE. The 1-year survival rate, 2-year survival rate, 30-day mortality rate, complete response rate, disease control rate, complete necrosis rate, non-response rate, objective response rate, progressive disease rate, and recurrence did not differ significantly between patients who underwent C-TACE and patients who underwent DEB-TACE. Patients who undergo DEB-TACE might have a higher complete response rate, disease control rate, and 3-year survival rate than patients who undergo C-TACE. Safety did not differ significantly between C-TACE and DEB-TACE.
