Treatment of metastatic liver tumors using stereotactic ablative radiotherapy

Figure 1 Images demonstrating tumors close to the critical structures. In these cases stereotactic ablative radiotherapy could prove useful than radiofrequency ablation or other alternative non-surgical therapies. A more fractionated regimen would be useful to minimise toxicity when abutting luminal structures. A: tumor abutting vascular trunk; B: Tumor close to luminal gastrointestinal structures (stomach in this case).
