Trial Information

Prospective and Retrospective Register Study of the German Breast Group (GBG) for Diagnosis and Treatment of Breast Cancer in Pregnancy

Breast cancer is the most common cancer malignancy in women of childbearing age after the
age of 25 years. Since the incidence of breast cancer under the age of 40 is increasing, and
women tend to delay pregnancy into later reproductive years, the coincidence of pregnancy
and breast cancer is increasing. About 1 in 1,000 pregnancies is complicated by breast
cancer. Nevertheless, little is known about the right therapy for the mother and the unborn
child. We are therefore carrying out a trial, collecting prospective and retrospective data
about pregnant women, with histological confirmed breast cancer. Data on the biology of the
tumour and placenta tissues is also collected. The anonymous data is collected in a
database.
