Cryoablation Combined with Iodine-125 Implantation in the Treatment of Cardiac Metastasis from Alveolar Soft Part Sarcoma: A Case Report.

Objectives: A 36-year-old Asian man was referred to our hospital with cardiac metastasis. He had a history of alveolar soft part sarcoma and initially underwent resection in 2005.

Methods: After exposing the tumor by thoracotomy, cryoablation was performed under ultrasound guidance. This treatment was combined with iodine-125 seed implantation to treat the cardiac metastasis.

Results: The patient had an uneventful recovery, and his cardiac function shows no obvious abnormalities. Imaging techniques suggest that cardiac metastasis was well controlled, and the patient is still alive 12 months after treatment.

Conclusions: Tumor cryoablation, combined with iodine seed implantations, may be regarded as a means of palliative treatment.
