Impact of microwave ablation on survival rates and recurrence in hepatic malignant tumors

This study aimed to evaluate the efficacy of percutaneous microwave ablation (MWA) for treating hepatic malignant tumors and to identify factors influencing tumor recurrence post-treatment.

A total of 249 patients with hepatic malignant tumors treated at the Shandong Cancer Hospital and Institute were included, and 101 patients were analyzed. Disease-free and overall survival rates were assessed at 1, 2, and 3 years post-MWA. Correlations between tumor recurrence and factors such as Child–Pugh B classification and lesion count were examined, and a meta-analysis was conducted to identify independent risk factors for recurrence.

The study found disease-free survival rates of 80.2%, 72.3%, and 70.3% at 1, 2, and 3 years post-MWA, with overall survival rates at 99%, 97%, and 96%. Significant correlations were observed between tumor recurrence, Child–Pugh B classification, and the number of lesions. Meta-analysis confirmed lesion count and Child–Pugh B classification as independent risk factors for recurrence following MWA treatment.

The study underscores the importance of considering Child–Pugh B classification and lesion count in predicting tumor recurrence after MWA for hepatic malignant tumors. These findings offer valuable insights for clinicians in decision-making and post-treatment monitoring.
