ESR1 and endometrioid adenocarcinoma: In this study, PR expression was associated with improved disease-specific survival in endometrioid carcinoma (log-rank p < 0.0001) and high-grade serous carcinoma (log-rank p = 0.0006), and ER expression was associated with improved disease-specific survival in endometrioid carcinoma (log-rank p < 0.0001) [100].
