Abstract
Gynecologic cancer is a serious global healthcare issue with high rates of mortality and morbidity. In recent years, tumor immunity and immunotherapy have attracted extensive attention for treatment of gynecological cancers. Indoleamine 2, 3-dioxygenase 1 (IDO1) plays a critical role in cancer immune escape, and its inhibition has been explored for immune-targeted therapies for many malignancies. However, knowledge about IDO1 involvement in the pathogenesis of gynecological cancers and its therapeutic potential is still evolving. In the current study, we integrated bioinformatics analysis of the prognostic value and immune function of IDO1 in gynecologic malignancies using Oncomine, GEPIA, HPA, TIMER, TISIDB, SurvExpress and Metascape database. Comprehensive analysis revealed that the transcription levels of IDO1 were significantly overexpressed in patients with gynecologic cancers, and IDO1-co-expressed gene signatures may be useful potential prognostic markers for gynecologic cancers. Furthermore, increased IDO1 expression correlated with immune infiltration cells, immune marker sets, and immunomodulators in gynecological cancers. These findings suggest that IDO1 plays an important role in immune infiltration and could potentially be an immunotherapeutic target for gynecological cancers. However, future large-scale and comprehensive research is required to validate our results.
