Immunohistochemical evaluation for P53 and VEGF (Vascular Endothelial Growth Factor) is not prognostic for long term survival in end stage esophageal adenocarcinoma / Avaliação imunoistoquímica do P53 e VEGF (Fator de Crescimetno Endotelial Vascular) não representa fator prognóstico para sobrevida a longo prazo na fase terminal do adenocarcinoma do esôfago

ABSTRACT

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 percent and 47.8 percent of tumors, respectively.

RESULTS:

P53 protein and VEGF expressions coincided in 26 percent 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.
RESUMO

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 por cento e 47.8 por cento dos tumors, respectivamente .

RESULTADOS:

As expressões de ambos coincidiram em 26 por cento 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.
