RESUMO
OBJECTIVE: To study the efficacy of transarterial chemoembolization (TACE) combined with high-intensity focused ultrasound (HIFU) in patients with middle-advanced liver cancer. PATIENTS AND METHODS: A total of 100 patients with middle-advanced liver cancer treated in our hospital from January 2015 to January 2018 were selected and randomly divided into TACE group (control group, n=50) and TACE combined with HIFU group (experimental group, n=50) according to different therapeutic regimens. The efficacy was observed after the operation, the blood was collected to detect the postoperative liver function indexes aspartate aminotransferase (AST) and alanine aminotransferase (ALT), the postoperative complications were observed. Also, the immune indexes cluster of differentiation 3+ (CD3+), CD4+, and CD8+ were determined. Moreover, the quality of life (QOL) score was compared between the two groups, the 1-, 2-, 3-, and 5-year survival rates were observed after the operation. Also, the changes in the levels of tumor markers α-L-fucosidase (AFU), alpha-fetoprotein (AFP), carbohydrate antigen 19-9 (CA19-9), and carcinoembryonic antigen (CEA) were observed. RESULTS: In experimental group, the levels of AST, ALT, and blood urea nitrogen (BUN) after the operation were significantly decreased (p<0.05), while the postoperative efficacy was significantly superior to that in control group (p<0.05). The incidence of postoperative complications was significantly reduced (p<0.05), the levels of CD3+, CD4+, CD8+, and natural killer (NK) cells were markedly increased (p<0.05). Also, the QOL score was evidently better than that in control group (p<0.05) and the 1-, 2-, 3-, and 5- year survival rates after the operation were evidently higher than those in control group (p<0.05). After treatment, the levels of AFU, AFP, CA19-9, and CEA were remarkably lower than those before treatment in both groups, while they were remarkably lower in experimental group than those in control group (p<0.05). CONCLUSIONS: TACE combined with HIFU in the treatment of patients with middle-advanced liver cancer can restore the hepatic metabolism, enhance the immunity, improve the QOL, prolong the survival time of patients, and significantly reduce the tumor markers. Also, it has fewer adverse reactions and definite overall efficacy, which is worthy of popularization and application.
