BCL2 and ovarian carcinoma: Paradoxically, some studies showed an improved survival in patients with high Bcl-2 expression [98B,104,105], and improved disease-free survival with high expression of Bcl-2 [98,101], in contrast to most studies that did not report a significant association between Bcl-2 expression in ovarian cancer tissues and prognosis [20,44,80,85,96,100,102,106,107,108,109,110,111,112].
