Despite advances in treatment, the overall survival rate remains low, emphasizing the need for ongoing research into early detection methods and novel therapeutic approaches. Understanding the molecular mechanisms underlying ovarian cancer pathogenesis is crucial for developing effective interventions and improving patient outcomes. This abstract highlights the complexity of ovarian cancer and underscores the importance of continued investigation into its biology and treatment.

Ovarian cancer is a complex and heterogeneous malignancy arising from the ovaries, which are the female reproductive glands responsible for producing eggs and hormones [1]. It is one of the most lethal gynaecological cancers, ranking fifth in cancer-related deaths among women globally. The World Health Organization estimates that around 313,000 new cases of ovarian cancer were diagnosed in 2020, with significant variation in incidence rates depending on geographical location and population demographics.

Ovarian cancer is categorized into several histological types, with epithelial ovarian cancer (EOC) being the most common, accounting for approximately 90% of cases. Other types include germ cell tumours and sex-cord stromal tumors, which are less prevalent. The diagnosis of ovarian cancer is particularly challenging due to the lack of effective early screening methods and nonspecific symptoms, such as abdominal bloating, pelvic pain, and changes in appetite [2-5]. As a result, many cases are diagnosed at advanced stages when the disease has spread beyond the ovaries, significantly diminishing treatment options and survival rates. Risk factors for ovarian cancer include genetic mutations, particularly in the BRCA1 and BRCA2 genes, which are linked to hereditary breast and ovarian cancer syndrome. Other factors influencing risk include age, family history, reproductive history, and hormonal factors. Despite advancements in treatment, including surgery, chemotherapy, and targeted therapies, the prognosis remains poor for many women diagnosed with advanced disease. Research efforts are increasingly focused on understanding the molecular and genetic underpinnings of ovarian cancer, aiming to identify potential biomarkers for early detection and novel therapeutic targets. As the field evolves, it is essential to enhance public awareness, improve screening strategies, and foster research to mitigate the impact of this devastating disease .

Ovarian cancer poses a significant public health challenge due to its high mortality rate and the complexity of its diagnosis and treatment [6]. Despite advancements in medical science, many women continue to be diagnosed at advanced stages, primarily because early-stage ovarian cancer often presents with vague and nonspecific symptoms. The lack of effective screening tools, such as a reliable blood test or imaging technique, hampers early detection efforts. Current biomarkers, including CA-125, have limitations in sensitivity and specificity, necessitating ongoing research into more reliable screening methods.

The epidemiological profile of ovarian cancer reveals important insights into its risk factors. Genetic predispositions, particularly mutations in the BRCA1 and BRCA2 genes, significantly increase the risk of developing ovarian cancer. Women with these mutations have a lifetime risk of approximately 40-60% for ovarian cancer, compared to the general population's risk of about 1.3%. Other risk factors include age, with the incidence rising sharply after menopause, and lifestyle factors such as obesity, smoking, and diet. Conversely, factors like oral contraceptive use, pregnancy, and breastfeeding may provide some protective effects.

The primary treatment for ovarian cancer involves a combination of surgery and chemotherapy. Optimal surgical intervention aims to achieve complete tumor removal (debulking) while preserving as much normal tissue as possible. Postoperative chemotherapy typically involves the use of platinum-based agents, such as cisplatin or carboplatin, combined with taxanes like paclitaxel. While many patients respond well initially, recurrence is common, particularly in advanced cases. Recent developments in targeted therapies and immunotherapy offer hope for improved outcomes. For instance, PARP inhibitors, which target tumors with BRCA mutations, have shown promise in prolonging progression-free survival. Similarly, agents that inhibit angiogenesis, such as bevacizumab, have been integrated into treatment regimens for recurrent disease. Immunotherapeutic strategies, including checkpoint inhibitors, are also under investigation, aiming to harness the body’s immune system to combat cancer [7].

Conclusion

The future of ovarian cancer management relies on continued research into its biology and treatment. Advances in genomics and molecular profiling are enhancing our understanding of ovarian cancer heterogeneity, leading to the identification of distinct subtypes with varying prognoses and treatment responses. These insights are paving the way for personalized medicine approaches that tailor treatments to individual patients based on their tumor characteristics. Moreover, the integration of liquid biopsies into clinical practice may provide non-invasive methods for early detection and monitoring of treatment responses. Ongoing clinical trials are crucial for evaluating novel therapeutic agents and combinations, as well as for exploring the role of lifestyle modifications in cancer prevention.
