Zusammenfassung
Das Mammakarzinom ist die häufigste Krebserkrankung der Frau, zunehmend sind auch Frauen betroffen, die ihre Familienplanung noch nicht abgeschlossen haben. Eine der gravierenden Nebenwirkungen der bei jungen Frauen häufig eingesetzten Chemotherapien ist die Schädigung der Ovarialfunktion, die u. U. bis zum Verlust der Fertilität führen kann. Eine frühzeitige Beratung über die möglichen fertilitätserhaltenden Maßnahmen ermöglicht in der Regel die Integration dieser Maßnahmen in das onkologische Therapieregime, ohne dass es zu einer Verzögerung des Behandlungsbeginns kommt. Nach einer lokal begrenzten Brustkrebserkrankung gibt es laut der aktuellen Datenlage keinen Grund, einer betroffenen Frau von einer Schwangerschaft abzuraten. Die Schwangerschaft scheint keinen negativen Einfluss auf die Prognose des weiteren Krankheitsverlaufs zu haben. Eine Erhöhung des Anomalierisikos durch Substanzen, die in der onkologischen Therapie verwendet werden, ist für die Nachkommen von Mammakarzinompatientinnen nicht zu befürchten, wenn die Schwangerschaft nach Absetzen der Medikation und unter Beachtung der Auswaschphase eingetreten ist.
Abstract
Breast cancer is the most common cancer in women, and an increasing number of women who have not completed their family planning are being affected. One of the most serious side effects of chemotherapy is damage to the ovaries and possible loss of fertility. Early counselling on the possibility of fertility preservation methods normally allows integration of these methods into the oncological treatment regimen, without delaying the start of treatment. According to current data, there is no reason to advise a woman with localised breast cancer against becoming pregnant. The pregnancy does not appear to have any negative effects on the further disease prognosis. An increase in the risk of anomalies as a result of the chemotherapy agents used should not be feared if the pregnancy occurs after the medication has been stopped and the drug washout period is observed.
