Prior studies have reported pulmonary function tests (PFT) before and after related and unrelated allogeneic hematopoietic stem cell transplantation (HSCT). However, limited data exist on the evaluation of lung function after haploidentical stem cell transplantation (HAPLO) with post-transplant cyclophosphamide (PTCY). We retrospectively reported the evaluation of PFTs at screening before HAPLO in 80 patients at 100 days and 1 year of follow-up. The proportion of surviving patients with available PFTs at 100 days and 1 year were 86% and 68%, respectively. During the follow-up period, four patients met the criteria for bronchiolitis obliterans syndrome and two for interstitial lung disease. Overall survival was 73% (95% CI 62–82%) at 2 years. We observed a significant reduction in diffusing capacity of the lungs for carbon monoxide (DLCO) corrected for the most recent hemoglobin concentration (DLCOc) at 100 days after HAPLO. However, an overall substantial stable pulmonary function was observed at 1 year. [ABSTRACT FROM AUTHOR]

We assessed the outcomes associated with thiotepa, busulfan and fludarabine (TBF) conditioning regimen in a cohort of 29 consecutive patients allografted for myelofibrosis (MF). The median age was 56 (range 42–70) years. According to the refined Dynamic International Prognostic Scoring System (DIPSS-plus), 15 (52%) patients were classified as high risk. Graft source was peripheral blood stem cells in 27 patients. Donor type was HLA-matched related (n = 5), matched unrelated (n = 16), mismatched unrelated (n = 1), and haploidentical (n = 7). All but 2 patients engrafted. The cumulative incidence (CI) of grade II–IV acute graft-versus-host disease (GVHD) was 21% (95% CI, 10–42) at day 100. The CI of chronic GVHD was 39% (95% CI, 23–65) at 3 years. The median follow-up period was 39 (range 14–60) months. Overall survival was 69% (95% CI, 50–83) at 3 years. No relapse was observed. TBF is a valid conditioning strategy in patients with MF. [ABSTRACT FROM AUTHOR]
