PSMB9, FOXJ1, IFT57, MAL, ANXA4, CTSH, SCRN1, MIF, LTBR, CTSD, KIFAP3, PSMB8, HSPA5, and LTN1 were recognised as independent risk factors by multivariate Cox analyses, suggesting that these 14 prognostic immune genes might have potential effects on the occurrence, progression and prognosis of tumours. The gene discussed is CTSD; the disease is neoplasm.
