Tumor Ablation

Tumor Ablation

The rapidly expanding field of tumor ablation now includes a variety of heat-based ablation modalities using laser, microwave, radiofrequency, and ultrasound energy sources. Among these, RF ablation has found the greatest clinical utility worldwide.

Creating a successful tumor ablation practice demands that physicians change the way they approach both cancer care and the practice of radiology.

Clear, effective imaging is vital to tumor ablation, but consensus on which imaging method to use when has been elusive. No imaging modality on its own is perfect, and what may work well in one situation will be ineffective in another.

Technology and procedures for tumor ablation continue to evolve. Experts are evaluating new techniques for protecting organs, reducing pain, and avoiding complications.

Journal articles this month compare different methods for treating kidney tumors, review new minimally invasive treatments for prostate lesions, and explain new techniques.

Journal articles this month include a look at RFA for prostate cancer, factors that influence thermal lesion sizes, and the incidence of postablation syndrome.

A special Interventional Oncology Symposium held at the RSNA meeting in December confirmed tumor ablation’s status as an accepted and growing therapy. The symposium, cosponsored by the RSNA and the Society of Interventional Radiology Foundation, drew standing room-only crowds to presentations about ablation and embolization methods, new technologies, and the basic science behind interventional oncology.
