Update Mammakarzinom 2020 Teil 2 – fortgeschrittenes Mammakarzinom: neue Substanzen und Einzug diagnostikabhängiger Therapien
Update Breast Cancer 2020 Part 2 – Advanced Breast Cancer: New Treatments and Implementation of Therapies with Companion DiagnosticsZusammenfassung
Für Patientinnen mit einem lokal fortgeschrittenen bzw. metastasierten Mammakarzinom wurden in den letzten Jahren neue und effektive Therapien wie CDK4/6-Inhibitoren, PARP-Inhibitoren und ein PD‑L1-Inhibitor eingeführt. In dieser Übersichtsarbeit wird ein Update zu den vorhandenen Studien mit ihrer Datenlage gegeben. Ebenso werden 2 innovative Anti-HER2-Therapien dargestellt (Trastuzumab-Deruxtecan und Tucatinib), für die die Ergebnisse aus neuen Studien berichtet worden sind. Molekulare Tests bieten die Möglichkeit, Patientinnenpopulationen zu definieren oder auch Therapieverläufe zu monitorieren. Dieses kann helfen, Patientinnen mit spezifischen Eigenschaften zu identifizieren, um diesen eine individuelle zielgerichtete Therapie im Rahmen von Studien zukommen zu lassen. In einer großen Studie konnte der Nutzen einer solchen Biomarker-Studie zum ersten Mal beschrieben werden.
Abstract
For patients with locally advanced or metastatic breast cancer, new and effective therapies such as CDK4/6 inhibitors, PARP inhibitors and a PD‑L1 inhibitor have been introduced in recent years. This review presents an update on the available studies with their data. In addition, two innovative anti-HER2 therapies are presented (trastuzumab-deruxtecan and tucatinib) for which the results from new studies have been reported. Molecular tests offer the possibility of defining patient populations or also monitoring courses of therapy. This can help identify patients with specific characteristics in order to provide them with individually targeted therapy within the framework of studies. In a large study, the benefit of such a biomarker study was able to be described for the first time.
