Abstract:
Ovarian cancer (OVCA) is one of the most lethal malignancies with a five-year relative survival below 50% by virtue of its high recurrence rate and inadequate early detection methods. For OVCA patients, modern approaches include debulking surgery, chemotherapies, angiogenesis inhibitors, poly ADP-ribose polymerase (PARP) inhibitors, and immunotherapies depending on the histological type and staging of the tumor. However, in most cases, simple standard treatment is not satisfactory. Thus, a more effective way of treatment is needed. Ferroptosis is a newly recognized type of regulated cell death marked by lipid peroxidation, iron accumulation and glutathione deprivation, having a connection with a variety of disorders and showing great potential in anti-tumor therapy. Intriguingly, a possible connection between ferroptosis and OVCA is shown on the basis of previously published findings. Furthermore, a growing number of ferroptosis protection pathways have been identified during the past few years with increasing ferroptosis regulators being discovered. In this review, we summarized several major pathways involved in ferroptosis and the study foundation of ferroptosis and ovarian cancer, hoping to provide clues regarding OVCA treatment. And some important issues were also raised to point out future research directions.
Insights
Ovarian cancer (OVCA) remains lethal due to recurrence. This review explores ferroptosis, a cell death process, as a potential new treatment strategy for ovarian cancer by examining its pathways and regulators.
Area of Science:
- Oncology
- Cell Death Mechanisms
- Biochemistry
Background:
- Ovarian cancer (OVCA) has a poor prognosis, with survival rates below 50% due to high recurrence and limited early detection.
- Current treatments like surgery, chemotherapy, and targeted therapies are often insufficient for effective OVCA management.
- Ferroptosis, a regulated cell death characterized by lipid peroxidation and iron dependency, presents a promising avenue for anti-cancer therapy.
Purpose of the Study:
- To review the major pathways involved in ferroptosis.
- To explore the foundational research connecting ferroptosis and ovarian cancer.
- To identify potential therapeutic strategies for OVCA based on ferroptosis.
Main Methods:
- Literature review of ferroptosis pathways and regulators.
- Analysis of existing studies on ferroptosis in ovarian cancer.
- Synthesis of findings to propose future research directions.
Main Results:
- Ferroptosis is a distinct cell death pathway with significant implications for various diseases.
- Emerging evidence suggests a link between ferroptosis and ovarian cancer development and progression.
- Numerous ferroptosis regulators and protective pathways have been identified.
Conclusions:
- Ferroptosis represents a novel therapeutic target for ovarian cancer.
- Understanding ferroptosis pathways may offer new treatment strategies beyond conventional methods.
- Further research is needed to elucidate the role of ferroptosis in OVCA and develop targeted therapies.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
