ABSTRACT
INTRODUCTION: The objective of the study was to assess the impact of the previous use of immune-checkpoint inhibitors (ICIs) on the clinical course of Hodgkin Lymphoma (HL) patients undergoing autologous hematopoietic stem cell transplantation (ASCT).
METHODS: A single-center, retrospective chart review of adult HL patients who received ASCT from January 1, 2014, to December 31, 2019, was conducted. Primary endpoints included the length of stay (LOS) and the composite outcome of late-onset noninfectious fever (LONIF) or late-onset hypotension (LOH) requiring intravenous fluid (IVF) resuscitation. Secondary endpoints included number of days until neutrophil engraftment, documented infections, and corticosteroid use.
RESULTS: A total of 52 HL patients were included. Nine (17%) received ICI before ASCT, and 43 (83%) patients underwent standard salvage chemotherapy. The composite outcome of LONIF or LOH requiring IVF resuscitation was significantly higher in patients previously treated with ICIs compared with those who received standard non-ICI salvage chemotherapy (78% vs. 33%; P = .022). The differences between the median LOS and time to neutrophil engraftment were not statistically significant (P = .94 and P = .083, respectively). All LONIF patients received systemic corticosteroids with symptom resolution.
CONCLUSION: The composite outcome of LONIF or LOH requiring IVF resuscitation was significantly higher in patients who received prior ICI salvage therapy. LOS and time to neutrophil engraftment were not affected by prior ICI therapy. Early institution of steroids may prevent the evolution of additional sequelae associated with engraftment or engraftment-like syndrome that can complicate ASCT.
