Abnormal secretion of estrogen plays an important role in it. This study aimed to explore the estrogen metabolism and conversion mechanism of endometrial cancer patients, of which estrogen sulfotransferase (SULT) and steroid sulfatase (STS) are important regulatory factors. By collecting 50 endometrial cancer tissue specimens and 10 normal endometrial tissue specimens as control group, the protein expression levels of SULT1E1 and STS were detected by immunohistochemistry technology, and their expression in endometrial cancer and its relationship with clinical pathological features of patients were analyzed. The results showed that the expression of SULT and STS in endometrial cancer tissue specimens was significantly higher than that in control group, and was closely related to the clinical pathological features of patients such as 精品文档---下载后可任意编辑endometrial cancer grading, depth of invasion, lymph node metastasis, etc. This study revealed the important role of SULT and STS in the occurrence and development of endometrial cancer, providing new ideas for its treatment and prevention.【Keywords】estrogen sulfotransferase; steroid sulfatase; endometrial cancer; immunohistochemistry
