For hepatocellular carcinoma (HCC) patients who are not candidates for liver transplant or resection, lesion ablation can be a curative treatment. With multiple ablation options available and still under investigation, it can be challenging to navigate the differences between them. In this episode, Dr. Tyler Sandow hosts a discussion with interventional radiologists Dr. Kirema Garcia-Reyes, Dr. Sabeen Dhand, and Dr. Kevin Burns on the various ablation options for HCC and when to use each one.

SYNPOSIS
The doctors first discuss Barcelona-Clinic Liver Cancer (BCLC) Stage A patients, where lesion size and location are key factors in deciding between ablation and transarterial therapies. They then compare cryoablation and microwave ablation, highlighting that cryoablation offers better visualization and control of the ablation zone, while microwave ablation is more effective for treating larger lesions.
Dr. Burns introduces histotripsy, a noninvasive treatment that uses ultrasound energy to mechanically ablate tumors. He shares his experiences as an early adopter of this technology and discusses how intraoperative cone beam CT can help treat lesions located near critical structures or those poorly visualized on ultrasound. Finally, Dr. Garcia-Reyes and Dr. Berman provide insights into patient selection, pre-procedural imaging, and technical tips for Y90.
