Allgemeine Überlegungen zur Systemtherapie in Abhängigkeit von Subtyp

Bei bestehender Indikation zur Chemotherapie sollte unbedingt die

Möglichkeit der neoadjuvanten Chemotherapie erwogen werden. ++ HR+/HER2- und “niedriges Risiko”:

Endokrine Therapie ohne Chemotherapie ++

HR+/HER2- und “hohes Risiko” Konventionell dosierte AT-basierte Chemotherapie ++ Dosisdicht und dosiseskaliert in Fällen mit hoher Tumorlast + Sequentielle endokrine Therapie ++

HER2+ Trastuzumab plus ++

• Sequentiell A/T-basierte Protokolle mit T + H ++ • Anthrazyklin-frei, mit Carboplatin + • Anthrazyklin-freies, taxan-haltiges Regime bei geringer Tumorlast +

• Dosisdicht und dosiseskaliert in Fällen mit hoher Tumorlast + TNBC

Konventionell dosierte AT-basierte Chemotherapie ++ Dosisdicht und dosiseskaliert + Neoadjuvante Platin-haltige Chemotherapie +

4.1 Anwendungsgebiete

Metastasierter Brustkrebs

Perjeta ist zur Anwendung in Kombination mit Trastuzumab und Docetaxel bei erwachsenen Patienten

mit HER2-positivem metastasiertem oder lokal rezidivierendem, inoperablem Brustkrebs indiziert, die

zuvor noch keine anti-HER2-Therapie oder Chemotherapie zur Behandlung ihrer metastasierten

Erkrankung erhalten haben.

Neoadjuvante Behandlung von Brustkrebs

Perjeta ist in Kombination mit Trastuzumab und Chemotherapie bei erwachsenen Patienten zur

neoadjuvanten Behandlung von HER2-positivem lokal fortgeschrittenem, entzündlichem oder frühem

Brustkrebs mit hohem Rezidivrisiko indiziert (siehe Abschnitt 5.1).

Krebszellen nutzen verschiedene Mechanismen, um einer Immunerkennung zu entgehen

Herunterregulierung der Antigenpräsentation, wodurch die Erkennung durch T-Zellen beeinträchtigt wird1

Reduzierte Expression von Liganden für kostimulatorische Moleküle wie B7.1 und des induzierbaren ko-stimulatorischen Liganden (ICOSL) auf APCs, die zu fehlerhaften Immunfunktionen führt2

Bildung eines immunsuppressiven Mikromilieus, wodurch es zur Rekrutierung oder Förderung der Differenzierung oder Expansion suppressiver Immunzellen kommt2

Expression inhibitorischer Rezeptoren, z. B. PD-L1 und PD-L2, die zur T-Zell-Inhibition führt3

Zusammenfassung 1

�Die primär systemische Chemotherapie sollten allen Frauen angeboten werden, bei denen eine adjuvante Chemotherapie aufgrund der Tumorbiologie indiziert ist

�Das Erreichen einer pathologischen CR ist derzeit in bis zu 80% der Fälle möglich. Diese Patientinnen können als geheilt betrachtet werden.

�Eine erweiterte adjuvante endokrine Therapie ist nur in bestimmten Risikosituationen indiziert.

�Die Verlängerung einer 5-jährigen Behandlung mit einem Aromatasehemmer ist nur in Ausnahmefällen gerechtfertigt

Zusammenfassung 2

• Die Einführung der cdk4/6 Inhibitoren, zusätzlich zu einer endokrinen Therapie, hat zu einer hochsignifikanten Verbesserung der Überlebensdaten geführt

• Die Identifikation von „immunologischen“ Subtypen, und deren Behandlung mit Checkpointinhibitoren könnte das Behandlungsspektrum zusätzlich erweitern

• Die Nutzung zell-freier DNA könnte invasive Diagnostik verringern, und zusätzlich die aktuelle Tumordynamik wiedergeben
