Zusammenfassung
Hintergrund
Die Therapie mit Chimeric-antigen-receptor(CAR)-T-Zellen hat sich als neue Therapieform in der Onkologie etabliert. Im Rahmen einer Therapie mit CAR-T-Zellen kommt es regelhaft zu schweren Nebenwirkungen.

Review der Literatur zu CAR-T-Zell-Therapie, Toxizitäten und Nebenwirkungsmanagement
Ergebnis
Das „cytokine release syndrome“ (CRS) und das „immune effector cell-associated neurotoxicity syndrome“ (ICANS) treten regelhaft im Rahmen einer Therapie mit CAR-T-Zellen auf. Das CRS kann von einer milden grippeähnlichen Symptomatik bis hin zu einem Multiorganversagen führen. Bei ICANS kann sich letztendlich ein lebensbedrohliches Hirnödem entwickeln. Bei der Pathophysiologie des CRS spielt insbesondere das Interleukin‑6 eine entscheidende Rolle. Die Pathophysiologie des ICANS ist nicht vollständig verstanden. Das Management richtet sich nach dem Schweregrad gemäß Grading der American Society for Transplantation and Cellular Therapy (ASTCT). Beim CRS werden Tocilizumab und Kortikosteroide, für das ICANS Kortikosteroide empfohlen.
Diskussion
Nach einer CAR-T-Zell-Therapie kommt es regelhaft zu potenziell lebensbedrohlichen Komplikationen. Weitergehende Therapieansätze sind bislang nicht gut untersucht. Eine interdisziplinäre Zusammenarbeit zwischen Intensivmediziner*innen, Hämatolog*innen, Neurolog*innen und Ärzt*innen anderer Fachabteilungen ist von entscheidender Bedeutung. Aufgrund der steigenden Patientenzahlen ist von einer Zunahme an Patienten mit Notwendigkeit einer intensivmedizinischen Behandlung im Rahmen einer CAR-T-Zelltherapie auszugehen.
Abstract
Background
CAR‑T cell therapy has been implemented as clinical routine treatment option during the last decade. Despite beneficial outcomes in many patients severe side effects and toxicities are seen regularly that can compromise the treatment success.
Methods
Literature review: CAR T‑cell therapy, toxicities and their management
Results
The cytokine release syndrome (CRS) and the immune effector cell-associated neurotoxicity syndrome (ICANS) are seen regularly after CAR T‑cell treatment. CRS symptoms can range from mild flu-like symptoms to severe organ dysfunction requiring vasopressor therapy, mechanical ventilation and other intensive care support. ICANS symptoms usually develop later and can range from disorientation and aphasia to potentially life-threatening brain edema. IL‑6 is a key factor in the pathophysiology of CRS. The pathophysiology of ICANS is not fully understood. The ASTCT consensus grading is recommended to stratify patients for different management options. An interdisciplinary team including hematologist, intensivist, neurologists and other specialties is needed to optimize the treatment.
Discussion
Severe and potentially life-threatening toxicities occur regularly after CAR T‑cell therapy. Treatment strategies for CRS and ICANS still need to be evaluated prospectively. Due to the increasing number of patients treated with CAR T‑cells the number of patients requiring temporary intensive care management due to CRS and ICANS is expected to increase during the next years.
