Aquaporin 3 Expression in Endometrioid Carcinoma of the Uterine Body Correlated With Early Stage and Lower Grade.

Aquaporin 3 Expression in Endometrioid Carcinoma of the Uterine Body Correlated With Early Stage and Lower Grade. Pathol Oncol Res. 2020 May 08;: Authors: Watanabe T, Sato K, Kono T, Yamagishi Y, Kumazawa F, Miyamoto M, Takano M, Tsuda H Abstract Aquaporins (AQPs) are a family of transmembrane water channel proteins distributed in various human tissues. Recent studies revealed that AQPs play important roles in cancer biology. Few studies have documented the relationship between the prognosis, stage, and histological grade of uterine endometrioid carcinoma, with AQP expression. Hence, the present study aimed to investigate this relationship between uterine endometrioid carcinoma and AQP expression. We retrospectively reviewed records of the patients who underwent surgery for uterine body cancer between 1990 and 2010 at the National Defense Medical College Hospital, Saitama, Japan. In 241 cases of endometrioid carcinoma, we immunohistochemically examined the expression of AQP 1, 2, 3, 4, and 5, and their relationship with clinicopathological parameters and the patients' prognosis. We investigated the relationship between the clinicopathological parameters and AQP3 expression, and found that as the FIGO stage and histological grade progressed, the percentage of AQP3 expression tends to decrease. Furthermore, we analyzed progression-free survival/overall survival (PFS/OS) using the log-rank test, and found that the AQP3-positive group ha...
