Breast cancer and pregnancy

Area of Science:

• Oncology
• Obstetrics and Gynecology
• Public Health

Background:

• Breast cancer in premenopausal women is uncommon.
• Pregnancy-associated breast cancer (PABC) presents unique diagnostic and therapeutic challenges.
• Understanding the incidence and outcomes of PABC is crucial for clinical management.

Purpose of the Study:

• To determine the incidence of breast cancer in premenopausal women associated with pregnancy.
• To analyze diagnostic and treatment delays in PABC cases.
• To evaluate obstetrical and survival outcomes for patients with PABC.

Main Methods:

• Retrospective review of 194 premenopausal women with breast cancer.
• Analysis of cases diagnosed during pregnancy or postpartum.
• Assessment of treatment protocols, including surgery and adjuvant chemotherapy.
• Evaluation of obstetrical outcomes and patient survival.

Main Results:

• Sixteen of 194 (8.2%) premenopausal women were diagnosed with breast cancer in association with pregnancy (8 pregnant, 8 postpartum).
• Significant delays in referral for diagnosis and treatment were observed in both groups.
• Standard surgical therapy was used for early-stage disease; adjuvant chemotherapy presented challenges.
• All patients had favorable obstetrical outcomes, and survival rates were comparable to the general PABC literature.

Conclusions:

• Pregnancy-associated breast cancer is a rare but significant clinical entity in premenopausal women.
• Timely diagnosis and treatment are critical despite challenges posed by pregnancy.
• Current management strategies offer favorable outcomes for both mother and child.
