Further, 65% (11/17) benign specimens showed epithelial Bcl-2 staining in more than 50% of their epithelial cells, whereas, 18% (2/11) and 29% (8/28) normal and ovarian cancer tissues, respectively, displayed epithelial Bcl-2 staining to the same extent (Table 2). This evidence concerns the gene BCL2 and ovarian cancer.
