Die Immuntherapie stellt einen Fortschritt in der Krebsbehandlung dar - zdmaa Die Immuntherapie stellt einen Fortschritt in der Krebsbehandlung dar
Unser Immunsystem hat nur einen Zweck: den Schutz vor Krankheiten. Einige Krebsarten können jedoch unser Immunsystem überwältigen und Krebszellen können sich trotz aller Bemühungen unseres Körpers vermehren. Glücklicherweise haben Forscher eine neue Klasse von Medikamenten namens Immuntherapie entwickelt, die einem stummen Immunsystem helfen kann, Krebs zu bekämpfen.
Die Immuntherapie wurde in der Zeitschrift Science als der größte wissenschaftliche Durchbruch des Jahres 2013 bezeichnet. Wir befinden uns an einem Wendepunkt, „da sich die längst überfälligen Bemühungen, das Immunsystem gegen Tumore zu entfesseln, auszahlen“ mit einer wachsenden Zahl von Patientenerfolgsgeschichten, sagten die Herausgeber. . Immuntherapeutika wirken, indem sie bestimmte Teile des Immunsystems stimulieren oder Signale von Krebszellen neutralisieren, die die Immunantwort blockieren.
Die Idee, unser Immunsystem zur Behandlung von Krebs zu nutzen, stammt aus dem späten 19. Jahrhundert, als der New Yorker Chirurg Dr. William Cooley entdeckte, dass die Tumore einiger Krebspatienten schrumpfen, wenn der Patient nach der Operation eine Infektion entwickelt. Cooley entwickelte eine Methode zur Induktion von Fieber, um eine Immunantwort zu stimulieren, aber sein Ansatz wurde aufgegeben, als er mit der Strahlentherapie begann.
Die Forschung zur Immuntherapie nahm Mitte bis Ende des 20. Jahrhunderts deutlich zu. Nach Hunderten von klinischen Studien und vielen Stunden im Labor beginnen die Forscher, die Mechanismen zu identifizieren, die die Immuntherapie zum Erfolg führen würden. Eine der größten Entdeckungen war die Entdeckung, dass bestimmte Moleküle in T-Zellen ausgeschaltet wurden, wenn sie auf Krebszellen trafen. Forscher haben Medikamente entwickelt, um zu verhindern, dass diese Moleküle aufhören, und um das Immunsystem am Laufen zu halten.
Im Jahr 2011 hat die Food and Drug Administration mit Ipilimumab (Yervoy®) das erste „Checkpoint-Inhibitor“-Immuntherapie-Medikament für fortgeschrittene und metastasierende Melanome zugelassen. Andere Medikamente wirken ähnlich, zielen jedoch auf andere Moleküle ab. Pembrolizumab (Keytruda®) zielt auf das in T-Zellen vorkommende Protein 1 (PD-1) des programmierten Todes ab und wurde kürzlich von der US-amerikanischen Food and Drug Administration zur Behandlung von fortgeschrittenem Melanom zugelassen und wird bei anderen Krebsarten untersucht. Nivolumab (Opdivo®) ist bei einigen Patienten mit Hautkrebs sowie bei Patienten mit Nierenkrebs und nicht-kleinzelligem Lungenkrebs wirksam.
Checkpoint-Inhibitoren sind nur eine Art von Medikamenten in einer breiten Klasse von Immuntherapien, zu denen auch gehören:
Krebsimpfstoffe: Impfstoffe, die zur Vorbeugung oder Behandlung von Krebs eingesetzt werden, sind injizierte Substanzen, die die Immunantwort gegen bestimmte Krankheiten aktivieren. Sipuleucel-T (Provenge®) ist der einzige von der FDA zugelassene Impfstoff zur Behandlung von Krebs, insbesondere von fortgeschrittenem Prostatakrebs, der auf eine Hormontherapie nicht mehr anspricht. Gardasil®, Gardasil 9® und Cervarix® sind vorbeugende Impfstoffe gegen Gebärmutterhalskrebs.
Zytokine: Diese Proteine kommen natürlicherweise in kleinen Mengen in unserem Körper vor und fungieren als Botenstoffe, um Signale an das Immunsystem zu senden. Zum Beispiel ist ein Zytokin namens Interleukin-2 durch das Medikament Desleukin® (Proleukin®) in viel größeren Mengen verfügbar, als unser Körper produzieren kann. Das Medikament hilft dem Körper, aufgeladene Immunzellen zu bilden, die Krebs abtöten. Aldesleucin ist von der FDA für Patienten mit metastasiertem Nierenkrebs und metastasiertem Melanom zugelassen.
