AKAP4 and neoplasm: Of the 20 survival‐related TSGs, 2 were previously reported CT genes, including TSGA10 and AKAP4. TGCT patients with higher expression of TSGA10 had a significantly worse survival than those with low expression when using both PFI (HR = 4.05, P = 2.99 × 10−4) and DFI (HR = 5.66, P = 1.20 × 10−4) as clinical endpoints after controlling for age and tumor stage (Figure 4B, Table S10).
