Conversely, a higher IFN-γ/IMS ratio was associated with poor prognosis in uveal melanoma (UVM) (HR = 1.67; 95% CI: 1.17–2.38), uterine carcinosarcoma (UCS) (HR = 1.49; 95% CI: 1.01–2.20) and brain lower-grade gliomas (LGG) (HR = 1.41; 95% CI: 1.06–1.88), suggesting that these cancers may have different antitumour immune responses than those cancers mentioned previously. Here, IFNG is linked to uveal melanoma.
