Freezing Fort Knox: Mesenteric Carcinoid Cryoablation.

Area of Science:

• Oncology
• Interventional Radiology

Background:

• Neuroendocrine tumors (NETs) are slow-growing but prone to liver metastasis.
• Hepatic metastasis is facilitated by the portal venous system and the liver's immunosuppressive environment.
• Standard treatment for metastatic NETs involves aggressive surgical debulking.

Purpose of the Study:

• To describe CT-guided percutaneous cryoablation with hydrodissection for an inoperable mesenteric carcinoid tumor with liver metastases.
• To evaluate the safety and efficacy of this technique in preventing further metastasis and potentially stimulating systemic immunity.

Main Methods:

• CT-guided percutaneous cryoablation was performed on a mesenteric carcinoid tumor.
• Hydrodissection was utilized to prevent tumor spread during the procedure.
• The technique aimed to prime the immune system for systemic eradication of malignancy.

Main Results:

• CT-guided percutaneous cryoablation is a minimally invasive procedure.
• The technique possesses inherent analgesic properties.
• Cryoablation may enhance immune system sensitization against tumor antigens.

Conclusions:

• Percutaneous cryoablation with hydrodissection is a viable option for intra-abdominal malignancies.
• This approach is suitable for patients who are poor surgical candidates.
• The procedure is demonstrated to be safe, effective, and minimally invasive.
