Preservation of fertility in female cancer patients: from experiment to everyday clinical practice.

In this volume of Deutsches Arzteblatt, a group from the University Department of Gynecology at Erlangen report Germany’s first case of the reimplantation of cryopreserved ovarian tissue. This marks a step forward in efforts to preserve fertility for patients undergoing cancer treatments. Strategies to preserve fertility in cancer patients are much needed. The numbers of long-term cancer survivors especially in childhood, adolescence, and early adulthood are rising constantly. The five-year survival rate for Hodgkin’s lymphoma in childhood, for example, is over 90%, and almost 80% for acute lymphoblastic leukemia (1). In the year 2010, one in every 715 adults will have a history of childhood cancer (2). These good long-term prospects open the possibility of life choices, of which the choice to have a family is one. This is however compromised by the fact that the cytotoxic damage to the gonads resulting in infertility is a predictable consequence of oncological treatment, whether chemotherapy or radiotherapy.
