Eine internationale klinische Studie für Kinder und Jugendliche mit atypischen teratoiden/rhabdoiden Tumoren

Descrizione riassuntiva della sperimentazione (Fonte di dati: BASEC)

Atypische Teratoide, Rhabdoide Tumoren (ATRT) sind seltene, hoch aggressive Tumoren des Zentralnervensystems (Gehirn und Rückenmark). Von dieser Erkrankung sind vor allem sehr junge Kinder unter 22 Monaten betroffen. Die Heilungsaussichten von Patientinnen und Patienten mit einem ATRT konnten in den letzten Jahren zwar verbessert werden, sind aber trotz intensiver Behandlungsansätze insgesamt nach wie vor ungünstig. SIOPE ATRT01 ist eine internationale Therapieoptimierungsstudie. Die Studie wurde für Kinder und Jugendliche entworfen, um einen entscheidenden Schritt in Richtung einer Therapieverbesserung zu gehen, die Heilungsraten zu erhöhen und gleichzeitig die Nebenwirkungen so niedrig wie möglich zu halten. Die Studie soll einige entscheidende Fragen in Bezug auf die Behandlung von ATRT klären. Dazu gehört unter anderem die Frage, ob eine Hochdosis-Chemotherapie mit anschliessender Stammzelltransplantation nicht weniger wirksam ist als eine Strahlentherapie, aber weniger Spätfolgen hat.

Interventi esaminati (p. es. medicamento, terapia, campagna) (Fonte di dati: BASEC)

Entsprechend der Standardtherapie erhalten alle Teilnehmenden nach der Operation zunächst drei Zyklen Chemotherapie. Patientinnen und Patienten, bei denen die Erkrankung nach den drei Zyklen weiter fortgeschritten ist, werden außerhalb dieser Studie behandelt. Alle anderen Patientinnen und Patienten werden je nach Alter und Risikoprofil einem von drei Behandlungsteilen zugeordnet:

Teil A: Für Patientinnen und Patienten im Alter von 12-35 Monaten ist das primäre Ziel dieser Studie die Nicht-Unterlegenheit einer Hochdosis-Chemotherapie mit anschliessender Stammzelltransplantation gegenüber einer Strahlentherapie zu prüfen. Teilnehmende erhalten entweder eine Hochdosis-Chemotherapie mit einer autologen Stammzelltransplantation oder eine herkömmliche Chemotherapie und eine Strahlentherapie. Die Ergebnisse in beiden Gruppen werden hinsichtlich der Wirkungen und Nebenwirkungen miteinander verglichen, um zu sehen, ob die eine Behandlung wirksamer ist als die andere. Um sicher zu gehen, dass die Patientinnen und Patienten in den beiden Gruppen gleich verteilt sind, werden die Kinder mittels Zufallsprinzip einer der beiden Gruppen zugeordnet.

Teil B: Als Standardtherapie für Kinder unter zwölf Monaten gilt in der Schweiz eine konventionelle Chemotherapie gefolgt von einer Hochdosis-Chemotherapie mit anschliessender Stammzelltransplantation. Dies entspricht auch der Studientherapie. Das primäre Ziel dieses Studienteils ist es, Therapiedaten inklusive der Nebenwirkungen aller Patientinnen und Patienten zu erfassen und auszuwerten.

Teil C: Für Patientinnen und Patienten im Alter von über 36 Monaten gilt eine Strahlentherapie als vertretbar. Kinder dieser Altersgruppe werden mit einer konventionellen Chemotherapie behandelt und zusätzlich bestrahlt. Auch bei diesem Studienteil werden Therapiedaten inklusive der Nebenwirkungen erfasst und ausgewertet.

Begleitend zur medizinischen Behandlung werden alle Teilnehmenden neuropsychologisch untersucht. Mittels speziell zusammengestellten Test werden die kognitive Entwicklung und Lebensqualität der Patientinnen und Patienten überprüft. Diese Untersuchungen sollen ermöglichen, Folgen der Erkrankung und der Therapie auf die kognitive Entwicklung frühzeitig zu erkennen und entsprechende Maßnahmen zu ergreifen. Es wird überprüft, ob Kinder, die in jungem Alter eine Strahlentherapie erhalten, später in ihrer kognitiven Entwicklung stärker beeinträchtigt sind als solche, die eine Hochdosis-Chemotherapie erhalten haben. Die Ergebnisse der Untersuchungen sollen langfristig helfen, die Therapiemethoden der Patientinnen und Patienten zu verbessern, um Nebenwirkungen der Behandlung zu verringern und die Therapien besser verträglich zu machen.
