Expression of bax and bcl-2 gene in mucous adenocarcinoma of the rectum / 中国普通外科杂志

ABSTRACT

ObjectiveTo determine the relationship between the expression of bax and bcl-2 gene in mucous adenocarcinoma of rectum and patient′s prognosis.MethodsImmunohistochemical method was used to evaluate monoclone antibody of bax and bcl-2 protein in 38 cases of mucous adenocarcinoma of the rectum. ResultsThe positive-staining rate of bax was 77.8% in Dukes′ A and B stage compared to 45.0% in Dukes′ C stage( ? 2=4.260,P=0.039).The intensity of positive-staining of bax over bcl-2 was significantly correlated with tumor stage(P=0.04) and the survival (P=0.001).ConclusionThe expression rate of bax and bcl-2 gene was very high in mucous adenocarcinoma of large bowel, and it might have a prognosis implications in patients with colonic mucous adenocarcinoma.
