Subsequently, US-guided PMC was performed in randomly assigned ten VX2 tumor-bearing rabbits (the other ten as controls). US images after ablation were obtained and analyzed. Three rabbits with double VX2 tumors were used as pathological observation at weeks 0, 1, and 4 of ablation. The therapeutic efficacy was evaluated by tumor growth, physical examinations, survival time, survival rate and metastasis of tumors and histopathology.Results: Ultrasound monitoring indicated that the tumor growth rate was 463.09% at the 2nd to 3rd weeks, and PMC was performed during this period under real-time US guidance. After microwave ablation, some tumors were greatly reduced or undetectable at week 8. Moreover, no flow signals were detected by US. The survival rates at 2 and 3 months in the treatment group and control group were 100%, 70% and 10%, 0%, respectively, while the metastatic rates were 10%, 30% and 90%, 100%, respectively (P< 0.05).Conclusion: The proliferation and metastasis of rabbit VX2 breast carcinoma were monitored by US imaging, and US-guided percutaneous microwave ablation was proven to be a safe, effective and minimally invasive therapeutic option for treating breast cancer in rabbits, showing potential clinical applicability.Keywords: percutaneous microwave, VX2 rabbit models, breast cancer, ultrasound |
