Rationale: High morbidity and high mortality are the main features of non-small cell lung cancer (NSCLC). Radiofrequency ablation, which produces a large amount of heat to kill tumor cells, is one effective way to treat this disease. Patient concerns: We report the case of a 74-year-old man who presented with a 1-month history of right chest pain. His left lung was removed 12 years prior. Chest computed tomography (CT) revealed a mass in the right lower lobe. Diagnoses: An excision biopsy of the mass showed lung squamous cell carcinoma. Interventions: We performed radiofrequency ablation. Outcomes: The patient underwent 3.5 and 10 months of follow-up, with a partial response and complete remission, respectively. Lessons: CT-guided radiofrequency ablation is a safe and an effective minimally invasive treatment option. Radiofrequency appears to be a valuable alternative to surgery for inoperable patients presenting with a single-lung NSCLC.
Rationale:The morbidity and mortality of small cell lung cancer (SCLC), an uncommon malignancy of the lung, remain high. Radiofrequency ablation (RFA) creates heat to destroy cancer cells and is usually used to treat non-SCLC, but not SCLC.Patient concerns:An 85-year-old male presented with a 2-month history of a productive cough with white phlegm and a 2-day history of hemoptysis. Chest computed tomography revealed a mass in the right lower lobe.Diagnoses:An excision biopsy of the mass showed SCLC.Interventions:We treated the tumor with RFA.Outcomes:At the 2-year follow-up examination, the efficacy of the RFA was evaluated as a partial response.Lessons:RFA can improve the prognosis of SCLC and should be considered for its treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
