Stereotactic ablative body radiation therapy (SBRT) involves the precise delivery of high-dose radiation to cancer tumor targets. A novel SBRT platform offers a first-of-its-kind gimbaled radiation accelerator mounted within a pivoting O-ring gantry capable of dynamic image-guided tumor tracking. Here, we describe dynamic tumor tracking for lung targets.

We developed novel intrinsic multifunctional nanovesicles called porphysomes, which have structure-dependent fluorescence self-quenching and unique photothermal properties, thus functioning as potent photothermal therapy agents. We formulated porphysomes using high pressure extrusion and investigated their photothermal therapy efficacy in a xenograft tumor model.

This video describes the procedure for performing irreversible electroporation (IRE) for non-thermal ablation of pancreatic tumors in mice. Both subcutaneous (SQ) and orthotopic tumors can be successfully treated with IRE in a highly controlled setting, facilitating various studies post-procedure.
FAQs
Radiofrequency, microwave, and cryoablation differ primarily in the energy environment they create within the target. Radiofrequency and microwave approaches use heat, whereas cryoablation uses extreme cold. These distinct conditions disrupt tumor tissue and produce localized cell death, allowing clinicians to select among techniques within image-guided treatment.
Imaging contributes more than initial tumor localization. Ultrasound, computed tomography, or magnetic resonance imaging can guide probe placement, support real-time monitoring as treatment proceeds, and assist treatment planning and follow-up. This continuing imaging role helps clinicians maintain procedural precision and evaluate the treated area within the broader care process.
The therapeutic goal is localized destruction rather than broad treatment of surrounding tissue. Energy delivery or extreme cold disrupts tumor tissue, while precise probe guidance supports preservation of nearby structures when that is clinically important. This tissue-sparing emphasis is one reason ablation has a role in personalized cancer care.
A typical workflow begins with imaging to identify the tumor and plan the treatment path, followed by image-directed probe placement and delivery of the selected energy. Imaging then remains part of monitoring and follow-up. The procedure therefore links localization, controlled energy delivery, and assessment rather than treating these as separate steps.
Clinicians consider image-guided tumor ablation for selected tumors, particularly when surgery is unsuitable or when preserving surrounding tissue is important. Its use in these circumstances places the technique within interventional oncology, where localized treatment can support individualized cancer management rather than serving as a universal replacement for surgery.
Before treatment, imaging supports planning and probe targeting; during treatment, it enables monitoring; afterward, it contributes to follow-up. This sequence gives clinicians information across the treatment timeline and helps integrate ablation into interventional oncology and personalized cancer care. It also connects treatment delivery with ongoing assessment of the treated area.
