Metachronous Lung Cancer Developing after 11 Years of Chemo-Radiotherapy in a Patient with Non-Small Cell Lung Carcinoma

摘要

The success rate of the chemo-radiotherapy is low for the patients with lung cancer. The risk of second primary malignancy (SPM) in lung cancer survivors is also not well reported in the literature. A 77-year-old male patient was given chemo-radiotherapy (KT_RT) 11 years ago because of the low respiratory function of the non-small cell lung cancer in the right lung. He applied to hospital for complaining cough. NSCLC was diagnosed and doctors performed left lower lobectomy to the patient. We presented the case in which the patient was cured after chemo-radiotherapy which is an extremely rare condition and the development of a second tumor 11 years later.
