Influence of Previous Inflammatory Bowel Disease on the Outcome of Allogeneic Hematopoietic Stem Cell Transplantation: A Matched-Pair Analysis

Abstract

The idiopathic inflammatory bowel diseases (IBDs) Crohn's disease and ulcerative colitis are associated with increased risk of hematologic malignancies. Allogeneic hematopoietic stem cell transplantation (HSCT) could be a curative strategy in this setting, but has been thought to be associated with increased nonrelapse mortality (NRM). We conducted a national French retrospective analysis of patients with IBD who underwent allogeneic HSCT for hematologic malignancies and were matched with 3 controls according to recipient, donor, and transplant characteristics. Between 2004 and 2015, 18 patients with IBD underwent allogeneic HSCT. With a median follow-up of 33 months for the patients with IBD and 57 months for controls, the cumulative incidence of grade II-IV acute graft-versus-host disease (GVHD) was 39% for the patients with IBD and 40% for controls (hazard ratio [HR], 1.10; P = .82). The cumulative incidence of chronic GVHD at 48 months was 52% for the patients with IBD and 43% for controls (HR, 0.92; P = .89). Nonrelapse mortality at 48 months was 19% for the patients with IBD and 11% for controls (HR, 4.93; P = .067). Overall survival at 48 months was 59% for the patients with IBD and 60% for matched controls (HR, 1.35; P = .56). In conclusion, IBD should not be considered a contraindication for transplantation, and its impact on comorbidity indexes should be reduced.
