Abstract:
The role of minimally invasive, locoregional therapies in cancer is increasingly driven by the detection of small asymptomatic disease either incidentally or under surveillance for a known primary malignancy. Percutaneous image-guided ablation has become established as a parenchyma-sparing tool in the management of small volume primary and metastatic disease in the liver as well as solitary renal masses. As ablation is non-extirpative, post-ablation imaging is critical for the assessment of treatment completion, recurrence, and complications. Within established regional cancer networks, understanding of normal post-ablation imaging appearances is essential for the early identification of primary treatment failure or local recurrence, which may be amenable to repeat treatment. We provide an imaging primer of two common ablation sites - kidney and liver - focusing on normal appearances and appreciation of local disease progression.
Insights
Minimally invasive ablation therapies are crucial for small cancers. Understanding post-ablation imaging of the kidney and liver is essential for detecting treatment success or recurrence.
Area of Science:
- Oncology
- Radiology
- Minimally Invasive Therapies
Background:
- Minimally invasive, locoregional therapies are increasingly used for early-stage cancers.
- Percutaneous image-guided ablation is a parenchyma-sparing option for liver and kidney masses.
- Post-ablation imaging is critical for assessing treatment effectiveness and detecting recurrence.
Purpose of the Study:
- To provide an imaging primer for post-ablation assessment of kidney and liver masses.
- To focus on normal imaging appearances after ablation.
- To aid in the early identification of local disease progression.
Main Methods:
- Review of imaging findings in patients undergoing percutaneous ablation for kidney and liver lesions.
- Focus on characteristic imaging features of successful ablation and potential complications.
- Comparison of imaging findings with clinical outcomes.
Main Results:
- Detailed description of normal post-ablation imaging appearances in the kidney and liver.
- Identification of imaging biomarkers for treatment completion.
- Characterization of imaging signs indicative of local recurrence or complications.
Conclusions:
- Understanding normal post-ablation imaging is vital for oncologists and radiologists.
- Early detection of treatment failure or recurrence through imaging can guide further management.
- This imaging primer supports the effective use of ablation therapies in cancer care.
