The Presence of Resistant & Stem Cell-Like Tumor Cells as a Problem in Ovarian Cancer

Epithelial ovarian cancer is the fifth leading cause of cancer-related deaths of women in the United States and Europe and ranks as the second most common type of gynecological malignancy. Most cases are diagnosed in advanced stages and although the response rates to platinum-based chemotherapy are high, the majority of patients nevertheless have poor survival rates. Although the reasons for these poor outcomes are likely to be multifactorial, one particular area of interest has recently focused on hematogenous tumor cell dissemination that has been shown to originate from disseminated tumor cells (DTCs) in the bone marrow (BM) and circulating tumor cells (CTCs) in the blood. Here, we demonstrate that the negative prognostic impact of CTCs and DTCs arise from specific cellular phenotypes and are associated with platinum-resistance and stem cell-associated proteins.
