摘要: The prognosis of ovarian carcinoma, even in the early stages (FIGO I-II), continues to present a challenge despite advances understanding pathophysiology and treatment. In series 106 patients with epithelial carcinomas FIGO IA-IIC, number prognostic factors (age, stage, histopathologic type, tumor grade) were studied relation important regulators apoptosis (p53, bcl-2, bax). Immunohistochemical techniques used. All received adjuvant radiotherapy after primary surgery. Univariate analysis showed that expression p53 was highly significantly associated grade (P = 0.007) survival status 0.046). Positive bcl-2 staining serous 0.0002) endometrioid subtypes, but not rate. A positive bax younger age 0.012) more favorable probability survival. significant association between tumors subtypes grades noted. most subgroup combination negative staining. multivariate Cox analysis, 0.0006) 0.020) independent factors.
