Prospective on ovarian cancer: why prevent?

Area of Science:

• Gynecologic Oncology
• Cancer Prevention
• Epidemiology

Background:

• Ovarian cancer is a leading cause of cancer death in women, with a low five-year survival rate (42%) compared to other gynecologic cancers.
• Late diagnosis is common, with over 70% of cases detected after the disease has spread, contributing to poor prognosis.
• Unlike other gynecologic cancers, ovarian cancer lacks a known premalignant phase, hindering early detection and prevention efforts.

Purpose of the Study:

• To highlight the critical need for ovarian cancer prevention strategies.
• To explore potential avenues for early detection and intervention.
• To emphasize the role of oral contraceptives in reducing ovarian cancer risk.

Main Methods:

• Analysis of ovarian cancer incidence, mortality, and survival statistics by stage at diagnosis.
• Review of factors influencing ovarian cancer development, including ovulation and hormonal influences.
• Evaluation of existing prevention strategies, such as oral contraceptive use.

Main Results:

• Only 23% of ovarian cancers are diagnosed at Stage I, contrasting sharply with higher early-stage diagnoses for endometrial, breast, and cervical cancers.
• Oral contraceptive use for five or more years is associated with up to a 50% reduction in epithelial ovarian cancer incidence.
• Lack of early symptoms and screening methods leads to delayed diagnosis and advanced-stage disease.

Conclusions:

• Every effort must be directed towards the prevention of ovarian cancer.
• Future prevention strategies should focus on identifying premalignant conditions, developing screening tools, and creating interventions.
• Oral contraceptives represent a viable and effective method for ovarian cancer prevention, particularly in high-risk populations.
