A case of primary non-small cell lung cancer with synchronous small cell lung cancer

Abstract

Synchronous multiple primary lung cancer is an uncommon and difficult to distinguish from metastatic disease. The present study reported an extremely rare case of a 66-year-old male with non-small lung cell cancer in the left lobe and synchronous small cell lung cancer in the right lobe. The diagnosis of multiple primary lung cancer not only depends on biopsy pathology, but also requires molecular biology results. This is of great significance for the management and prognosis of multiple primary lung cancer. The management of patients with non-small cell lung cancer-small cell lung cancer produces certain unique challenges, which may require individualized treatment modality that may not strictly comply with standard practices in the setting of a single tumor.
