Objective: To explore the therapeutic effects of ultrasound-guided microwave ablation and radio frequency ablation for liver cancer patients. Methods: Seventy-eight patients with microwave ablation were rolled into the experimental group and 56 patients with radio frequency ablation were in the control group. This study was conducted from March 1, 2019 to June 30, 2020 in our hospital. Based on Convolutional Neural Networks (CNN) and Migration feature (MF), a new ultrasound image diagnosis algorithm CNNMF was constructed, which was compared with AdaBoost and PCA-BP based on Principal component analysis (PCA) and back propagation (BP), and the accuracy (Acc), specificity (Spe), sensitivity (Sen), and F1 values of the three algorithms were calculated. Then, the CNNMF algorithm was applied to the ultrasonic image diagnosis of the two patients, and the postoperative ablation points, complications and ablation time were recorded. Results: The Acc (96.31%), Spe (89.07%), Sen (91.26%), and F1 value (0.79%) of the CNNMF algorithm were obviously larger than the AdaBoost and the PCA-BP algorithms (P<0.05); in contrast with the control group. The number of ablation points in the experimental group was obviously larger, and the ablation time was obviously shorter (P<0.05); the experimental group had one case of liver abscess and two cases of wound pain after surgery, which were both obviously less than the control group (four cases; five cases) (P<0.05) Conclusion: In contrast with traditional algorithms, the CNNMF algorithm has better diagnostic performance for liver cancer ultrasound images. In contrast with radio frequency ablation, microwave ablation has better ablation effects for liver cancer tumors, and can reduce the incidence of postoperative complications in patients, which is safe and feasible. doi: https://doi.org/10.12669/pjms.37.6-WIT.4885 How to cite this:Riaz A, Sughra U, Jawaid SA, Masood J.

It has been a long time since tumor ablation was first tested in patients with liver cancer, especially hepatocellular carcinoma. Since than it has become a first line treatment modality for hepatocellular carcinoma. Over the years, the indications of thermal ablation have expanded to colorectal cancer liver metastases and intrahepatic cholangiocarcinoma as well. Together with the new indication for ablation, new ablation devices have been developed as well. Among them microwave ablation shows potential in replacing radiofrequency ablation as the preferred method of thermal ablation in liver cancer. The debate whether radiofrequency or microwave ablation should be the preferred method of treatment in patients with liver cancer remains open. The main purpose of this review is to offer some answers to the question: Microwave ablation in liver tumors: a better tool or simply more power? Various clinical scenarios will be analyzed including small, medium, and intermediate size hepatocellular carcinoma, colorectal cancer liver metastases and intrahepatic cholangiocarcinoma. Furthermore, the advantages, limitations, and technical considerations of MWA treatment will be provided also.
