# Cryoablation as local therapy in patients with locally recurrent thyroid cancer: Two case reports

## TL;DR

Cryoablation is presented as a promising minimally invasive treatment for locally recurrent thyroid cancer, with successful outcomes in two case reports.

## Contribution

The paper contributes two case reports demonstrating the feasibility of cryoablation for thyroid cancer recurrence.

## Key findings

- Follow-up ultrasound showed complete involution in one patient after cryoablation.
- The second patient experienced a 73% volume reduction of the lesion.
- No delayed complications were observed in either case.

## Abstract

The local surgical treatment of thyroid cancer recurrence poses significant challenges, particularly when addressing areas affected by extensive scar tissue. Cryoablation of local recurrences might be a promising minimally invasive alternative, especially for patients who are not ideal surgical candidates or prefer nonsurgical interventions. This report discusses 2 cases of recurrent thyroid cancer successfully managed with curative intent cryoablation. Follow-up ultrasound revealed complete involution in the first patient, and 73% volume reduction of the lesion in the second patient. No delayed complications were observed. It underlines the potential of cryoablation as a feasible treatment option for local recurrence of thyroid cancer and advocates for future research to better define its role within thyroid cancer management protocols.
