Learning objectives The main objective of this study is to present the main indications for ultrasound-guided microwave thermal ablation and how to properly select patients who may benefit from this therapy.We will also describe the technique and devices as well as potential adverse effects, limits and complications.
Read more Background According to data published in 2021 breast cancer is the most commonly diagnosed tumor worldwide surpassing lung cancer. [1]In recent years, this has led research to focus on developing therapies with minimal impact on patient’s lives.In this context, ablation has emerged as a promising procedure. Ablation involves the local application of extreme temperatures—cold in the case of cryoablation, or heat in the case of radiofrequency and microwaves—or the application of electrical pulses in the case of electroporation (Fig. 1). The...
Read more Findings and procedure details Case 1The first case is an 87-year-old woman with grade II invasive ductal carcinoma refractory to hormone therapy scandidate for microwave ablation. (Fig. 8).On the one month follow-up mammography an inflammatory halo is observed, which corresponds to the necrosis of the tumor's fat. This finding is confirmed on the additional ultrasound study, where we can see a nodule with poorly defined margins and hyperechogenicity of the adjacent fat. On the 3-month follow-up mammography the previously described findings become more evident....
Read more Conclusion Ultrasound-guided microwave thermal ablation is an alternative in the treatment of early-stage breast cancer. It is a minimally invasive treatment with few complications, making it very useful for elderly patients, those with high surgical risk (ASA III-IV), or those with other surgical contraindications. The results in our patients are promising, and while long-term studies are necessary to establish recurrence and survival rates, we aim to share our experience over the past few years with approximately 25 patients from our center.
