Pregnancy-Associated Breast Cancer: What Radiologists Must Know

Unveiling the Role of Pregnancy-Associated Plasma Protein A (PAPP-A) in Pregnancy-Associated Breast Cancer: A Comprehensive Review

Pregnancy-associated breast cancer (PABC) presents unique challenges due to its occurrence during or shortly after pregnancy. Pregnancy-associated plasma protein A (PAPP-A) has emerged as a potential biomarker and regulator in PABC. This comprehensive review examines the role of PAPP-A in PABC, highlighting its involvement in tissue remodeling and cancer progression. Molecular mechanisms linking PAPP-A to breast cancer, including signaling pathways and interactions with other molecules, are explored. The review also discusses the diagnostic and therapeutic implications of PAPP-A dysregulation in PABC, emphasizing the need for further research to elucidate underlying mechanisms and develop targeted therapies. Collaborative efforts among researchers, clinicians, and industry stakeholders are essential for translating findings into clinically relevant interventions to improve outcomes for PABC patients.

Breast cancer and pregnancy: Why special considerations prior to treatment are needed in multidisciplinary care

Breast cancer diagnosed during pregnancy poses ethical and professional challenges. Clinical management of that condition should ensure the safety of both the mother and fetus. Clinical trials on breast cancer exclude pregnant women, so sufficient evidence with which to formulate guidelines for the management of these patients is lacking. Failing to undergo a breast examination during pregnancy, breast symptoms explained by physiological changes such as pregnancy, and unnecessary abortions after the diagnosis of breast cancer lead to worse outcomes for these patients. Multidisciplinary teams including breast surgeons, obstetricians, radiologists, pathologists, and anesthesiologists need to make an early diagnosis and comprehensively evaluate patients in different gestational weeks and with different stages of breast cancer in order to optimize outcomes.
