Abstract:
Objective:To investigate the expression of cluster proteins in endometrial cancer tissues and its correlation with estrogen receptor (ER) and progesterone receptor (PR).
Methods:We selected 120 cases of endometrial cancer tissue specimens and 120 cases of normal endometrial tissue specimens from January 2013 to December 2017 in the Maternal and Child Health Hospital of Huzhou.The expression of cluster proteins, ER and PR in tissues were determined by immunohistochemistry.
Results:The positive rate of cluster proteins in the endometrial carcinoma tissues(89.2%) was higher than that in the normal endometrial tissues(13.3%) (χ2=145.067, P<0.05). The positive expression rates of ER and PR in the endometrial carcinoma tissues(60.0%, 56.7%) were lower than those in the normal endometrial tissues(100.0%, 100.0%) (χ2=93.490, 96.698, all P<0.05). The cluster proteins was negatively correlated with ER and PR in the endometrial carcinoma tissues (r=-0.472, -0.513, all P<0.05). The expression of cluster protein and ER in the endometrial carcinoma were associated with FIGO stage, depth of myometrial invasion and lymph node metastasis of endometrial carcinoma(83.1% vs.93.0%, 82.6% vs.98.0%, 97.6% vs.84.6%; 81.7% vs.29.2%, 91.3% vs.17.6%, 19.5% vs.82.1%) (χ2=6.628, 7.228, 4.779; 33.062, 66.292, 43.984, all P<0.05), and were not associated with age, degree of differentiation and tumor diameter (all P>0.05). The positive expression of PR in the endometrial carcinoma was correlated with the FIGO stage and depth of myometrial invasion of the endometrial carcinoma(78.9% vs.24.5%, 84.1% vs.20.0%, χ2=34.919, 48.577, all P<0.05), and were not associated with age, degree of differentiation, tumor diameter and lymph node metastasis (all P>0.05).
Conclusion:The development of endometrial cancer is related to the overexpression of cluster proteins, and the expression of cluster proteins may be regulated by estrogen and progesterone.
