ESR1 and carcinosarcoma: The most significant favourable prognostic DEGs were ESR1, ANAPC4, RPS6KA1 and WFS1. There were 49 DEGs associated with an unfavourable prognosis, such as ERBB2, ARL4C, TUBB4A, TPX2, AURKA and CCNA2. This prognostic data is based only upon RNA expression data from the TCGA-UCEC dataset (n = 541), and thus does not include data from carcinosarcoma samples (TCGA-UCS).
