Breast cancer during pregnancy: A mini-review

BackgroundAs modern women delay childbearing, pregnancy-associated breast cancer (PABC) becomes a more frequent problem faced by oncologists, gynecologists, and obstetricians alike. However, no evidence exists concerning the management of this condition.MethodsWe summarized the current literature regarding epidemiology, pathology, diagnosis, treatment and prognosis of PABC. Data were collected by searching PubMed and Medline for the period from 1950 to 2007.ResultsThere are no randomized controlled trials regarding PABC management. Current evidence suggests that diagnosis may be carried out with limitations regarding staging; surgical treatment may be performed as for the non-pregnant women. Radiotherapy and endocrine therapy are contraindicated during pregnancy, while chemotherapy is allowed after the first trimester. Prognosis is considered poor. Subsequent pregnancy is allowed only 2 years after completing treatment.ConclusionsDue to lack of prospective randomized controlled clinical studies, both ongoing studies and future evidence are expected to solve problems related to breast cancer management during pregnancy.
