The correlation of the P53 protein expression in invasive cervical carcinoma with prognostic and clinical factors.

The analysis of p53 protein in cervical carcinoma correlated with clinical and prognostic factors was performed in a retrospective study with p53 expression detection by immunohistochemical technique. 120 slides of patients with squamous cell cancer at the Gynecologic Oncology Clinic and stored in the Department of Pathological Anatom at the School of Medicine of Botucatu were used. Age, ethnicity, parity, smoking habit, oral contraceptive use, age at first intercourse, histology, stage, treatment, and follow-up were the cofactors associated with p53 positivity. Fisher’s exact tests were carried out to analyze associations between p53 and variables, with p < 0.05 as the significant level. The study revealed a 43.3% frequency of patients with stage II disease and p53 positive rate with p = 0.001, and 64.2% frequency with p = 0.024 of patients whose first intercourse occurred between the ages of 15 and 20. These findings show the correlation between stage II disease and age at first intercourse with p53 positive in invasive cervical cancer. Fisher's exact test revelead these cofactors to be statistically significant and there was no association between the protein p53 with others prognostic and analyzed cofactors. The prognostic value of p53 in cervical cancer had been examined, with the conclusion that p53 is correlated to unfavorable prognosis.
