Percutaneous Cryoablation for Recurrent Head and Neck Tumors

Area of Science:

• Oncology
• Interventional Radiology
• Head and Neck Surgery

Background:

• Recurrent head and neck cancer after initial treatment poses significant management challenges.
• Salvage surgery is often not feasible for these patients.
• Novel minimally invasive techniques are needed for recurrent head and neck tumors.

Purpose of the Study:

• To evaluate the techniques and outcomes of cryoablation for recurrent head and neck cancer.
• To assess the efficacy and safety of cryoablation as a salvage therapy.
• To determine the local control rate in patients unsuitable for conventional salvage treatments.

Main Methods:

• Retrospective review of 11 patients undergoing 16 cryoablation procedures for recurrent head and neck cancer (2016-2020).
• Patients had prior surgery and/or radiotherapy.
• Efficacy assessed by local control rate (MRI/PET); complications and procedure details were documented.

Main Results:

• Cryoablation was performed in 11 patients with various recurrent head and neck tumors, many with prior extensive treatments.
• A local control rate of 45.4% was achieved at a mean follow-up of 11.7 months.
• Complications occurred in 4/16 procedures, with two major events (septic shock, recurrent nerve injury).

Conclusions:

• Cryoablation is a viable and effective salvage treatment option for recurrent head and neck tumors.
• It provides a valuable alternative for patients who cannot undergo salvage surgery.
• Careful patient selection and technique are crucial to minimize potential complications.
