Resumo Objective. the prognostic value of p53 codon72 polymorphism was analyzed in Brazilian women with cervical cancer. Methods. the present study consists of 148 women diagnosed and treated for invasive cervical carcinoma (FIGO stages Ib-IIIb) between 1992 and 2002, Demonstration of p53 polymorphism was performed in DNA extracted from paraffin-embedded sections using the polymerase chain reaction (PCR).Results. Among the 148 women, arg/arg was found in 99 (67%) and, arg/pro in 49 (33%). the overall survival (OS) curves (univariate) were different between arg/arg and arg/pro patients (P = 0.01). There was slightly increased risk of death for arg/arg patients (crude HR 2.2 CI 95% 1.2-4.0), which was not confounded by FIGO stages (adjusted FIR 2.4 CI 95% 1.3-4.3). for disease-free survival (DFS), two situations were considered: (1) 124 women who received any treatment, and (2) 118 who received FIGO-recommended treatment. in the first group, 59% of arg/arg patients presented recurrence as compared to 32% in the arg/pro group (P = 0.02), whereas in the second group, 61% of the arg/arg and 34% arg/pro showed recurrence (P = 0.04). the risk of recurrence adjusted by FIGO stage for the 124 patients was 2.4 (CI 95% 1.0-3.7) and for the 118 it was 1.9 (CI 95% 1.0-3.4). These adjusted models showed no confounding and no interaction.Conclusions. Despite the prognostic significance of p53 polymorphism in univariate survival analysis, there was no or only marginal evidence on the independent prognostic value of p53arg/arg in multivariate analysis. the more ominous prognosis of the homozygous (arg/ arg) patients was explained by the primary treatment, independent on the FIGO stage.
