However, inconsistent with the results of other tumours, high expressions of LILRB2 and LILRB4 were associated with better clinical outcomes in our study, while other studies showed that patients with high expressions of LILRB2 and LILRB4 predicted worse clinical outcomes [45, 46, 47, 48, 49, 50, 51, 52]. This evidence concerns the gene LILRB4 and neoplasm.
