Pediatric Nodular Lymphocyte-predominant Hodgkin Lymphoma: Treatment Recommendations of the GPOH-HD Study Group

Abstract

Nodular lymphocyte-predominant Hodgkin lymphoma (nLPHL) is a very rare disease in childhood and adolescence. In Germany, about 15 newly diagnosed patients present with this disease annually; this number comprises less than 10% of all pediatric Hodgkin lymphoma cases. Since the EuroNet-PHL-LP1 trial for early stage nLPHL patients stopped recruiting in Germany in October 2014, the GPOH-HD writing committee reviewed the literature and decided to deliver treatment recommendations for childhood and adolescent nLPHL patients. These guidelines shall be applicable to young nLPHL patients in European countries that will no longer be able to participate in nLPHL trials for young patients. Therefore, the EuroNet-PHL-nLPHL-registry will be installed to provide quality assured central review of staging and response assessment for registered patients by the Central Review Board of EuroNet-PHL in Halle/Leipzig, Germany.

Zusammenfassung

Das noduläre Lymphozyten-prädominante Hodgkin-Lymphom (nLPHL) ist eine sehr seltene Erkrankung im Kindes- und Jugenedalter mit ca. 15 Neuerkrankungen pro Jahr in Deutschland. Das sind weniger als 10% aller Hodgkin-Lymphome in dieser Altersgruppe. Die Rekrutierung für die EuroNet-PHL-LP1-Studie für Patienten mit frühen Stadien des nLPHL wurde im Oktober 2014 in Deutschland beendet. Deshalb führte die GPOH-HD-Studiengruppe einen Literaturreview durch und erstellte darauf basierend Therapieempfehlungen für nLPHL-Patienten im Kindes- und Jugendalter. Diese Empfehlungen sollen für alle Patienten in europäischen Zentren gelten, welche nicht mehr an nLPHL-Studien für diese Altersgruppe teilnehmen können. Zur Qualitätssicherung wird das EuroNet-PHL-nLPHL-Register eingerichtet. Hierbei stellt das Central Review Board der EuroNet-PHL in Halle/Leipzig für alle registrierten Patienten die Referenzbegutachtung der Bildgebung zur Stadienfestlegung und zur Beurteilung des Ansprechens auf die Therapie sicher.
