Μελέτη της προγνωστικής σημασίας του δείκτη κυτταρικού πολλαπλασιασμού Ki-67 και της συσχέτισής του με την έκφραση του αποπτωτικού δείκτη p53, με την ανίχνευση οιστρογονικών υποδοχέων καθώς και με τον φαινότυπο στον πορογενή καρκίνο του μαστού

Abstract

The aim of this prospective study is to assess the expression of the cell proliferation marker Ki-67, p53 and the antiapoptotic protein BCL-2 with the expression of Her-2-neu, hormone receptor status, clinical stage of the disease, local recurrence and 5-year survival .The study included 306 patients with primary ductal carcinoma of the breast. The clinical and pathologic parameters documented for each included sex, age, grade of differentiation, expression of hormone receptors and stage according to the TNM criteria.The mean age was 56 ± 14,5 years. 70.3 % showed positive staining for p53 protein and 72.6 % positive staining for bcl-2 protein. 54.8 % of patients expressed strong nuclear staining of the cell proliferation antigen Ki-67 in ≥ 20% of the cancerous cells. The expression of Ki-67 correlated significantly with tumors with malignant phenotype.The positive expression of bcl-2 was associated with neoplasias of good differentiation and earlier TNM stage and with benign phenotype ...
