Abstract Background Ovarian cancer is the most lethal gynecologic malignancy. The ovarian tumor microenvironment is comprised of tumor cells surrounding stroma and circulating lymphocytes an important component of the immune response in tumors. Previous reports have shown that the anti-apoptotic protein Bcl-2 is overexpressed in many solid neoplasms including ovarian cancers and contributes to neoplastic transformation and drug-resistant disease resulting in poor clinical outcome. Likewise studies indicate improved clinical outcome with increased presence of lymphocytes. Therefore we sought to examine Bcl-2 expression in normal benign and cancerous ovarian tissues to determine the .
