IL15 and neoplasm: The results of multivariate analysis showed that tumor size (OR = 2.213, 95% CI: 1.188–4.122, p = 0.012), tumor thrombus (OR = 2.385, 95% CI: 1.224–4.647, p = 0.011), and recipient IL-15 rs10519613 genotypes (CA/AA versus CC; OR = 2.214, 95% CI: 1.041–4.708, p = 0.039) were independent factors of predicting DFS, whereas tumor thrombus (OR = 2.302, 95% CI: 1.173–4.517, p = 0.015), UCSF criteria (OR = 2.209, 95% CI: 1.181–4.131, p = 0.013), and recipient IL-15 rs10519613 genotypes (CA/AA versus CC; OR = 3.152, 95% CI: 1.358–7.315, p = 0.008) were independent factors of predicting OS (Table 6).
