IL15 and uterine carcinosarcoma: The expression of IL-15 was positive correlated with OS (overall survival) in LUAD (p = 0.037), COAD (p = 0.045), COADREAD (p = 0.008), SKCM (p < 0.001), PCPG (p = 0.032), UCS (Uterine Carcinosarcoma, p = 0.014) and READ (p = 0.029) as a good prognostic marker performed by Cox proportional hazards regression model.
