WT1 is regarded as a specific and sensitive indicator of serous carcinomas of ovarian origin (Lizneva et al., 2016; Meczekalski et al., 2020), and studies have shown that the expression of WT1 in endometrial carcinoma is closely related to tumor hematopoiesis (Goodarzi et al., 2011). The gene discussed is WT1; the disease is serous adenocarcinoma.
