Breast cancer during pregnancy

Area of Science:

• Oncology
• Maternal-Fetal Medicine
• Medical Ethics

Background:

• Breast cancer diagnosis during pregnancy presents unique challenges.
• Management requires careful consideration of maternal and fetal well-being.
• Multidisciplinary decision-making is crucial for optimal outcomes.

Purpose of the Study:

• To review the management of breast cancer in pregnant patients.
• To discuss treatment modalities and their impact on the fetus.
• To evaluate the prognosis of pregnancy-associated breast cancer.

Main Methods:

• Review of current literature on pregnancy-associated breast cancer.
• Discussion of treatment options including surgery, chemotherapy, and radiation.
• Analysis of fetal risks associated with different treatment modalities.

Main Results:

• Radiation therapy should be avoided due to fetal complications.
• Chemotherapy in the second and third trimesters is linked to growth retardation and prematurity.
• Modified radical mastectomy is recommended for early-stage disease.
• Abortion may be considered for early-stage disease, but its therapeutic benefit is unclear.

Conclusions:

• Pregnancy-associated breast cancer management necessitates a tailored, multidisciplinary approach.
• Treatment decisions must balance maternal oncologic needs with fetal safety.
• Survival rates appear comparable to non-pregnant patients when matched for stage, despite more advanced initial disease presentation.
