Abstract

Allied to the current tendency to postpone childbearing to the later reproductive years, the incidence rate of pregnancy-associated breast cancer is increasing. Delayed diagnosis and suboptimal therapy worsen prognosis. General concepts concerning local and systemic treatment and staging workup should adhere as much as possible to those of young nonpregnant female patients. Clinicopathological tumor characteristics determine the appropriate treatment. Most diagnostic methods and treatments options including imaging, surgery, and chemotherapy are feasible during pregnancy depending on the gestational stage at diagnosis. However, the selection and timing of local and systemic therapies must be adapted to ensure safety of both the fetus and the mother. Treatment strategies should be established in a multidisciplinary team and the pregnant woman and the family should be clearly informed and involved in the decision-making progress. Premature delivery should be avoided, whenever possible. Radiotherapy, endocrine and anti-HER2 therapies as well as new breast cancer treatments are contraindicated during pregnancy and lactation. Since randomized studies are not feasible in patients with breast cancer during pregnancy, register studies need to be supported and international collaborations to be continued.
