Insights
Previous acute graft-versus-host disease (aGVHD) response impacts chronic GVHD (cGVHD) risk and severity. Steroid-dependent (SD) and steroid-resistant (SR) aGVHD are risk factors for cGVHD, with similar poor prognoses. Steroid-sensitive (SS) aGVHD is not a risk factor.
Area of Science:
- Hematology
- Immunology
- Oncology
Background:
- Chronic graft-versus-host disease (cGVHD) is a significant complication following allogeneic hematopoietic cell transplantation (HCT).
- Acute GVHD (aGVHD) response to first-line corticosteroids defines steroid-sensitive (SS), steroid-dependent (SD), and steroid-resistant (SR) groups.
- Understanding the relationship between prior aGVHD response and subsequent cGVHD is crucial for improving patient outcomes.
Purpose of the Study:
- To assess the incidence, risk factors, and clinical outcomes of cGVHD in patients with a history of SS, SD, or SR aGVHD.
- To compare these outcomes with patients who did not develop aGVHD.
- To determine if prior aGVHD response status predicts cGVHD severity and prognosis.
Main Methods:
- Retrospective, single-institution cohort study of 784 adult and pediatric HCT recipients for hematologic malignancies (2008-2016).
- Analysis of aGVHD incidence and response categories (SS, SD, SR).
- Evaluation of 3-year cumulative incidence of cGVHD and its association with prior aGVHD status and severity.
Main Results:
- The 3-year cumulative incidence of cGVHD was 25%.
- SD and SR aGVHD were identified as independent risk factors for developing cGVHD; SS aGVHD was not.
- cGVHD following SD and SR aGVHD had similar, poorer prognoses, contrary to the hypothesis of an intermediate prognosis for SD aGVHD.
Conclusions:
- Previous aGVHD response status, particularly SD and SR, are significant predictors of cGVHD development and severity.
- Patients with prior SD or SR aGVHD face similar adverse outcomes for subsequent cGVHD.
- These findings highlight the importance of considering aGVHD response in predicting and managing cGVHD post-HCT.
Abstract:
Chronic graft-versus-host disease (cGVHD) is a major limitation to the long-term success of allogeneic hematopoietic cell transplantation (HCT). Our prior study of acute GVHD (aGVHD) defined distinct treatment-response groups based on the response to first-line corticosteroids: steroid-sensitive (SS), steroid-resistant (SR), and steroid-dependent (SD) aGVHDs. We conducted a retrospective, single-institution, cohort study to assess the incidence, risk factors, and clinical outcomes of patients with cGVHD after a previous diagnosis of SS, SD, or SR aGVHD, compared with those with no history of aGVHD. Among 784 consecutive adult and pediatric recipients of HCT for hematologic malignancies between 2008 and 2016, 347 (44%) developed aGVHD, with 13% SS, 12% SD, and 19% SR aGVHD. The 3-year cumulative incidence of cGVHD was 25%. Among those with cGVHD, 39% had no prior aGVHD diagnosis, whereas among those with a prior aGVHD diagnosis, 16% had SS, 24% had SD, and 21% had SR aGVHD. Mild or moderate cGVHD was highest among those with preceding SD aGVHD, whereas severe cGVHD was most frequent among those with previous SR aGVHD. We identified SD and SR aGVHDs as significant independent risk factors for the development of cGVHD after allogeneic HCT, whereas SS aGVHD was not a risk factor. Our study demonstrates that cGVHD after SD aGVHD did not have an intermediate prognosis between SR and SS groups as hypothesized; rather, cGVHD after both SD and SR aGVHD have similar prognoses. Our findings suggest that previous aGVHD response states are important predictors of cGVHD severity and outcomes.
