Immunohistochemical evaluation for P53 and VEGF (Vascular Endothelial Growth Factor) is not prognostic for long term survival in end stage esophageal adenocarcinoma

Abstract

Objetivo: Correlacionar a expressão do p53 e VEGF com o prognóstico de pacientes submetidos à operação curativa para tratar adenocarcinoma do esôfago. Método: Foram estudados 46 pacientes com adenocarcinoma de esôfago, submetidos à ressecções curativas. As expressões do p53 e VEGF foram assessadas por imunoistoquímica em 52.2% e 47.8% dos tumors, respectivamente . Resultados: As expressões de ambos coincidiram em 26% dos casos sem correlação entre elas. Os fatores clinicopatológicos estudados não mostraram correlação significante. Não houve associação significante entre as expresses do p53 e VEGF na sobrevida a longo prazo. Conclusão: As expressões do p53 e VEGF não se correlacionaram com o prognóstico do adenocarcinoma do esôfago nos pacientes operados com ressecções curativas.

Objectives: To correlate the expression of p53 protein and VEGF with the prognosis of patients submitted to curative resection to treat esophageal adenocarcinoma. Methods: Forty-six patients with esophageal adenocarcinoma, submitted to curative resection, were studied. The expressions of p53 protein and VEGF were assessed by immunohistochemistry in 52.2% and 47.8% of tumors, respectively. Results: P53 protein and VEGF expressions coincided in 26% of the cases, and no correlation between these expressions was observed. None of the clinicopathological factors showed a significant correlation with p53 protein or VEGF expressions. There was no significant association between p53 protein and VEGF expressions and long-term survival. Conclusion: The expression of p53 protein and VEGF did not correlate with prognosis in esophageal adenocarcinoma patients submitted to curative resection.
