Large apical lung cancer treated with CT-guided percutaneous cryoablation

Abstract

Percutaneous lung ablation is increasingly used in the treatment of lung malignancies with good outcomes, but recurrence is commonly reported in ablation of lesions size larger than 3 cm. We report a 50-year-old female with a 9 cm nonsmall cell lung cancer involving the right upper lobe and apical chest wall causing severe neuropathic shoulder pain and significantly disturbing her daily activities. CT-guided percutaneous cryoablation was performed using a 4-phase protocol with complete eradication of the tumor. Follow-up imaging showed no evidence of recurrence 6 months after the procedure. The neuropathic pain was significantly improved after the procedure, and she was pain-free until her death due to metastatic disease elsewhere. To our knowledge, this is the first case of successful cryoablation for an exceptionally large lesion.
