IGF2BP1 and FOXM1 are shown to be critical in the regulation of caner progression. However, the prognostic value of IGF2BP1 in lung adenocarcinoma and its relationship with FOXM1 still remains unclear. In this study, the expression and biological significance of both IGF2BP1 and FOXM1 were evaluated in 188 lung adenocarcinoma, at mRNA and protein levels. We showed that mRNA and protein levels of IGF2BP1 and FOXM1 were upregulated in lung adenocarcinoma compared to adjacent non-cancerous tissues. High IGF2BP1 expression was correlated with a poor prognosis for lung adenocarcinoma patients. Moreover, IGF2BP1 expression was positively associated with FOXM1 expression. Meanwhile, the findings indicated that low IGF2BP1 combined with low FOXM1 expression, was negatively correlated with pathological stage and lymph node metastasis, predicted good outcomes for lung adenocarcinoma patients. Additionally, low IGF2BP1 and FOXM1 expression status, is an independent prognostic factor for lung adenocarcinoma after surgical resection. We demonstrate that low IGF2BP1 and FOXM1 expression can serve as a potential factor for the clinical diagnosis and prognosis of lung adenocarcinoma, and targeted inhibition of IGF2BP1 and FOXM1 might be an alternative strategy for the management of lung adenocarcinoma.
