FOXM1 and small cell lung carcinoma: The recent studies indicate that FOXM1 played an essential role in various aspects of tumorigenesis or tumor progression, including cell growth, metastasis, metabolic adaptations, and modulation of tumor immune response [8, 9, 17, 25], suggesting that it is a therapeutic vulnerability that can be exploited to develop potential therapies for multiple tumor types, including SCLC.
