title: [Relationship between P53 Protein Expression and Prognosis of Advanced Ovarian Serous Adenocarcinoma].
abstract: OBJECTIVE
  To study the expression of P53 protein in the advanced ovarian serous adenocarcinoma and explore its potential correlation with the clinicopathological features and prognosis of ovarian cancer.
  
  
  METHODS
  The immunohistochemical staining was used to detect the expression of P53 protein in 183 patients with advanced ovarian serous adenocarcinoma. The correlation of P53 protein with the clinicopathological features and its significance in the assessment of prognosis were explored.
  
  
  RESULTS
  The P53 protein expression was positive in 62.8% of the patients. Chi-square test showed that the overexpression of P53 protein was positively correlated with the elevation of serum CA125 and the two-tier grading of ovarian serous adenocarcinoma (P<0.001, P=0.038). Univariate analysis suggested that the prognosis of patients was associated with two-tier grading (P=0.007), lymph node metastasis (P=0.036), preoperative serum CA125 level (P=0.002), and P53 overexpression (P<0.001). Multivariate analysis showed that the International Federation of Gynecology and Obstetrics stage (P=0.038), lymph node metastasis (P=0.002), and overexpression of P53 (P=0.001) were independent prognostic factors.
  
  
  CONCLUSIONS
  The P53 protein expression is closely related to the prognosis of advanced ovarian serous adenocarcinoma and can be used as an important indicator for predicting the prognosis.
