Cancer stem cells markers in ovarian cancer: Clinical and therapeutic significance (Review)

Ovarian cancer is a gynecological neoplasm that can be found in women, which, due to diagnostic difficulties, is often detected at advanced stages when treatment becomes a significant problem. Moreover, in a number of cases there is a cancer recurrence and resistance to standard chemotherapy treatment. It has been suggested that cancer stem cells (CSCs) that were not eradicated during therapy may be responsible for this. For this reason, effective therapeutic methods eliminating CSCs are being studied, such as therapy targeting CSCs markers. In addition, numerous studies have also drawn attention to the usefulness of CSCs markers in predicting disease progression and assessing patient's prognosis as well as their importance in the development of treatment resistance. The present review presented research on selected CSCs markers, which may be of significant prognostic and therapeutic importance in ovarian cancer.
