Abstract:
Ovarian cancer (OC) is the most lethal gynecological malignancy due to tumor heterogeneity, the lack of reliable early diagnosis methods and the high incidence of chemoresistant recurrent disease. Although there are developments in chemotherapies and surgical techniques to improve the overall survival of OC patients, the 5-year survival of advanced OC patients is still low. To improve the prognosis of OC patients, it is important to search for novel therapeutic approaches. Cancer stem cells (CSCs) are a subpopulation of tumor cells that participate in tumor growth, metastasis and chemoresistance. It is important to study the role of CSCs in a highly heterogeneous disease such as OC, which may be significant to a better understanding of the oncogenetic and metastatic pathways of the disease and to develop novel strategies against its progression and platinum resistance. Here, we summarized the current findings about targeting methods against ovarian cancer stem cells, including related signaling pathways, markers and drugs, to better manage OC patients using CSC-based therapeutic strategies.
Insights
Targeting ovarian cancer stem cells (CSCs) offers a promising strategy to combat this lethal gynecological malignancy. Understanding CSCs and their pathways is key to developing new treatments for platinum-resistant ovarian cancer.
Area of Science:
- Gynecological Oncology
- Cancer Stem Cell Biology
- Translational Cancer Research
Background:
- Ovarian cancer (OC) remains a leading cause of cancer death due to its heterogeneity, late diagnosis, and chemoresistance.
- Current treatments offer limited survival benefits for advanced-stage OC patients.
- Cancer stem cells (CSCs) drive tumor growth, metastasis, and therapeutic resistance in OC.
Purpose of the Study:
- To review current findings on targeting ovarian cancer stem cells (CSCs).
- To explore CSC-related signaling pathways, markers, and drugs for OC management.
- To provide insights for developing novel CSC-based therapeutic strategies against OC progression and platinum resistance.
Main Methods:
- Literature review of studies on ovarian cancer stem cells.
- Analysis of signaling pathways, biomarkers, and therapeutic agents targeting CSCs.
- Synthesis of current knowledge on CSC-based strategies for OC.
Main Results:
- CSCs play a critical role in OC's heterogeneity, metastasis, and chemoresistance.
- Identification of key signaling pathways and markers associated with OC CSCs.
- Overview of existing and potential therapeutic agents targeting OC CSCs.
Conclusions:
- Targeting CSCs holds significant potential for improving OC patient prognosis.
- Understanding CSC biology is crucial for overcoming platinum resistance in OC.
- CSC-based therapeutic strategies represent a promising avenue for novel OC treatments.
