Zusammenfassung
Hintergrund
Frauen mit Brustkrebs in der Vorgeschichte leiden häufig unter klimakterischen Beschwerden. Eine menopausale Hormontherapie kann die Beschwerden zwar reduzieren, wird für dieses Patientenkollektiv jedoch aufgrund eines erhöhten Rezidivrisikos nicht empfohlen.
Ziel der Arbeit
Ziel ist die Darlegung der aktuellen Datenlage zur nichthormonellen Therapie für das genannte Patientenkollektiv.
Material und Methoden
In einer PubMed-Recherche wurden Studien und Metaanalysen von 1997 bis 2014 gesucht, die eine menopausale Hormontherapie mit einer nichthormonellen Therapie bei klimakterischen Symptomen nach Mammakarzinom verglichen.
Ergebnisse
Der Einsatz einer menopausalen Hormontherapie wird Frauen mit einer Brustkrebsdiagnose in der Vorgeschichte nicht empfohlen. Lebensstiländerungen sind die therapeutische Basis bei klimakterischen Beschwerden. Die tägliche Einnahme von 50–60 mg Isoflavon kann die Frequenz und Schwere von Hitzewallungen signifikant senken, wenn nicht mehr als 4 Episoden pro Tag auftreten. Cimicifuga racemosa mildert Hitzewallungen und depressive Symptome, zudem könnte eine Assoziation mit einem verlängerten krankheitsfreien Überleben bestehen. Die Wirksamkeit ist vergleichbar mit transdermalem Östrogen. Antidepressiva und Antikonvulsiva sind erwiesenermaßen wirksam und können als Zweitlinientherapie zum Einsatz kommen.
Schlussfolgerungen
Studien zur nichthormonellen Therapie klimakterischer Beschwerden zeigen, dass sie wirksam ist. Brustkrebspatientinnen haben also eine Therapiealternative zur Hormontherapie, die jedoch weiterhin die wirksamere Option darstellt. Weitere Studien sind notwendig, um die Effektivität und die Wirkmechanismen nichthormoneller Therapien weiter zu untersuchen.
Abstract
Background
Women with a history of breast cancer often suffer from climacteric symptoms. Hormonal therapies are known to reduce these symptoms but are not recommended in women with a history of breast cancer due to their potential adverse effects.
Objectives
The goal of this work is to give a literature overview on the efficacy of non-hormonal therapies as a therapy option for this patient group.
Materials and methods
In a PubMed search, relevant studies and meta-analyses from 1997–2014 that provided data on treatment of menopausal symptoms with hormonal replacement therapy versus nonhormonal therapies were identified.
Results
Hormone replacement therapy is not recommended in patients with history of breast cancer. Lifestyle modification is the basis in treating climacteric symptoms. Daily isoflavone intake of 50–60 mg can significantly reduce frequency and severity of hot flushes if not present more than 4 times/day. Cimicifuga racemosa allays hot flushes, depressive mood, and might be associated with prolonged disease-free survival. Its efficacy is comparable to transdermal estrogen. Off-label use of antidepressants like paroxetin and venlafaxin and anticonvulsants like gabapentin can be used as second line treatment with good efficacy.
Conclusion
Studies on nonhormonal therapies provide evidence for efficacy so that breast cancer patients do have an alternative treatment option for climacteric disorders. Nevertheless, hormone replacement is still more effective. More well-designed trials are needed to further investigate nonhormonal therapies.
