ARTICLE HIGHLIGHTS
Research background

Early-stage liver cancer is often treated with surgery and microwave ablation (MWA). MWA effectively preserves normal liver tissue and causes transient coagulation and necrosis of local liver tumor cells. However, due to technical limitations, cancerous liver tissue cannot be completely ablated; therefore, the probability of local tumor recurrence is high.

Research motivation

Improve the clinical efficacy and safety of percutaneous MWA in the treatment of small liver cancer.

Research objectives

This study aimed to investigate the clinical efficacy and safety of ultrasound-guided percutaneous MWA in the treatment of small liver cancer.

Research methods

A total of 118 patients treated for small liver cancer in The Central Hospital of Yongzhou from January 2018 to April 2019 were selected.

Research results

The operation time, blood loss, hospitalization time and medical expenses in the MWA group were lower than those in the laparoscopic group. The operation time, blood loss, hospitalization time, medical expenses, alanine aminotransferase and aspartate aminotransferase of the MWA group were lower than those of the laparoscopic group at 2 d and 1 wk after surgery. Compared with preoperatively, the serum alpha fetal protein, carcinoembryonic antigen and Treg levels of the two groups were reduced. The maximum area of the lesion in the MWA group was 4.86 ± 0.90 cm2, 1.24 ± 0.57 cm2, and 0.31 ± 0.11 cm2 before operation, 1 and 3 mo after operation, respectively. Of these, 58 people achieved a complete response, and 8 achieved a partial response. After 2 years of follow-up, the progression-free survival rate and overall survival rate of the MWA group were 37.88% and 66.67%, respectively, and the laparoscopic group were 44.23% and 76.92%, the difference was not statistically significant.

Research conclusions

The effect of ultrasounds-guided percutaneous MWA in the treatment of small liver cancer are similar to those of laparoscopic surgery. However, ablation causes less trauma and liver dysfunction.

Research perspectives

It can improve the clinical efficacy and safety of ultrasound-guided percutaneous MWA in the treatment of small liver cancer in the future.
