ACE2 and testicular germ cell tumor: In LIHC, ACE2 was beneficial to OS (HR = 0.55, log-rank P = 0.0017) but had no effect on RFS (HR = 1.34, log-rank P = 0.093) (Figures 3M,N), whereas the opposite was true in testicular germ cell tumor (TGCT) (OS: HR = 5.83, log-rank P = 0.1; RFS: HR = 9.79, log-rank P = 0.006) (Figures 3O,P).
