Allogeneic hematopoietic stem cell transplant outcomes in adults with inherited myeloid malignancies.

ABSTRACT: There is increasing recognition that pathogenic germ line variants drive the development of hematopoietic cancers in many individuals. Currently, patients with hereditary hematologic malignancies (HHMs) receive similar standard therapies and hematopoietic stem cell transplant (HSCT) approaches as those with sporadic disease. We hypothesize that patients with myeloid malignancies and deleterious germ line predisposition variants have different posttransplant outcomes than those without such alleles. We studied 472 patients with myeloid neoplasms, of whom 26% had deleterious germ line variants and 34% underwent HSCT. Deleterious germ line variants in CHEK2 and DDX41 were most commonly seen in American and Australian cohorts, respectively. Patients with deleterious germ line DDX41 variants had a higher incidence of severe (stage 3-4) acute graft-versus-host disease (GVHD) (38%) than recipients with deleterious CHEK2 variants (0%), other HHM variants (12%), or patients without such germ line variants (9%) (P = .002). Importantly, the use of posttransplant cyclophosphamide reduced the risk of severe acute GVHD in patients receiving HSCT for deleterious germ line DDX41-associated myeloid neoplasms (0% vs 53%, P = .03). Based on these results, we advocate the use of posttransplant cyclophosphamide when individuals with deleterious germ line DDX41 variants undergo allogeneic HSCT for myeloid malignancies, even when transplantation has been performed using wild-type donors.

Project description:Patient-reported outcomes among survivors of pediatric hematopoietic stem cell transplant (HSCT) are understudied. We compared symptom prevalence, health-related quality of life (HRQOL), and risk factors in adult survivors of childhood hematologic malignancies treated with HSCT to those treated with conventional therapy and noncancer controls. Survivors of childhood hematologic malignancies (HSCT N = 112 [70% allogeneic, 30% autologous]; conventionally treated N = 1106) and noncancer controls (N = 242) from the St. Jude Lifetime Cohort Study completed surveys assessing 10 symptom domains and SF-36 HRQOL summary scores. Chronic health conditions (CHCs) were validated by clinical assessment. Multivariable logistic regression reveals that compared with noncancer controls, HSCT survivors endorsed a significantly higher symptom prevalence in sensation (OR = 4.7, 95% confidence interval [CI], 2.6-8.4), motor/movement (OR = 4.3, 95% CI, 1.6-11.0), pulmonary (OR = 4.6, 95% CI, 1.8-11.8), and memory domains (OR = 4.8, 95% CI, 2.5-9.2), and poorer physical HRQOL (OR = 6.9, 95% CI, 2.8-17.0). HSCT and conventionally treated survivors had a similar prevalence of all symptom domains and HRQOL (all P > .05); however, HSCT survivors had a significantly higher cumulative prevalence for specific symptoms: double vision (P = .04), very dry eyes (P < .0001), and trouble seeing when wearing glasses (P < .0001). Occurrence of organ-specific CHCs, instead of transplant receipt, was significantly associated with a higher prevalence of all symptom domains (all P < .05) in adult survivors of childhood cancer, except for pain and anxiety domains. This study found that patient-reported outcomes were equally impaired between HSCT and conventionally treated survivors, but poorer in both groups compared with noncancer controls. Poor patient-reported outcomes in all survivors of childhood hematologic malignancies correlated with the presence of CHCs, whether treated with conventional therapy or HSCT.
