The survival analyses of shared ceRNAs among two HD cancer combinations have shown that 12 (KIF4A, KPNA2, TPX2, TUBA1C, RAD54L, MTFR2, ANLN, RACGAP1, FAM83D, KNSTRN, CCNE1 and DSCC1) out 88 and 6 (KPNA2, CCNF, CKAP2L, TTK, DEPDC1B and MCM2) out of 77 ceRNAs shared among BRCA‐UCEC and COLCA‐UCEC pairs, respectively, have exhibited the survival significance in both cancers included in the combinations. This evidence concerns the gene KNSTRN and cancer.
