Oophorectomy in breast cancer

Area of Science:

• Oncology
• Surgical Oncology
• Gynecologic Oncology

Background:

• Radical mastectomy is a standard breast cancer treatment.
• The role of ovarian ablation (OO) alongside mastectomy requires further investigation.

Purpose of the Study:

• To compare the efficacy of radical mastectomy alone versus radical mastectomy plus ovarian ablation (OO) in breast cancer management.
• To evaluate the impact of primary versus secondary ovarian ablation on patient survival and disease recurrence.

Main Methods:

• Retrospective analysis of breast cancer patients.
• Comparison of outcomes between radical mastectomy alone and radical mastectomy with primary or secondary ovarian ablation.
• Assessment of overall survival, disease-free interval, and metastasis rates.

Main Results:

• Patients undergoing radical mastectomy with primary ovarian ablation (OO) demonstrated improved overall survival compared to those without OO.
• A significant statistical difference was observed in the disease-free interval, favoring primary OO (40.2 months) over secondary OO (23.9 months).
• Primary OO resulted in significantly lower metastasis rates (18% in the second year, 38.6% over eight years) compared to expected recurrence rates without systemic treatment (72.7%).

Conclusions:

• Radical mastectomy combined with ovarian ablation (OO) is an effective, albeit old, procedure for managing breast cancer, particularly when performed as primary treatment.
• Primary ovarian ablation significantly improves disease-free intervals and reduces metastasis rates.
• Future research may focus on less invasive ovarian interventions to mitigate psychological impact in young women.
