Radiofrequency ablation of synchronous multiple primary lung cancer assisted by a magnetic navigation system: a case report.

With the widespread use of low-dose chest computed tomography (LDCT) screening for lung cancer in China, the incidence of multiple primary lung cancer (MPLC) has increased in recent years. Surgical resection is the standard treatment for early-stage MPLC; however, a significant proportion of patients with MPLC cannot undergo surgery. For patients with multiple pulmonary nodules who cannot tolerate surgical treatment, radiofrequency ablation (RFA) of multiple pulmonary lesions under the help of electromagnetic navigation system is a new treatment method. Compared with the traditional CT-guided percutaneous RFA, electromagnetic navigation-guided percutaneous RFA has higher accuracy and can effectively reduce postoperative complications. Herein we report a treatment procedure involving a 68-yearold man who presented with synchronous multiple tumor lesions in separate lung lobes. We utilized the electromagnetic navigation system to assist the clinician in inserting the RFA electrode into lung tumors. This case shows a feasible role for electromagnetic navigation-guided percutaneous RFA for early-stage MPLC.
