It is known that the risk of developing a second primary
respiratory or digestive tract tumor is high in treated small
cell lung cancers. This study aimed to present a patient with
metachronous small cell and non-small cell lung cancer. Thirteen
years before, the 78-year-old male patient received chemotherapy
and radiotherapy due to limited-stage small cell
cancer in the right lung. In the 6th year of the follow-up, he
underwent right upper lobectomy due to lung epidermoid carcinoma,
stage 2B. Over the 7 years following lobectomy, he
had been followed without any problems. In small cell lung
cancer patients with a survival of more than 2 years, the risk
of developing a second primary non-small cell lung cancer is
7-16 times higher compared to those who smoke but do not
have cancer. Patients should be followed closely so that a possible
metachronous tumor can be detected in the early stages.
