Ruxolitinib (INCB018424) is the first potent, selective, oral inhibitor of JAK1 and 2 being developed for clinical use. Its major cellular systemic effects are proliferation inhibition, apoptosis induction reduction in cytokine plasma levels, all mediated by drug's inhibition JAKs' ability to phosphorylate STAT. In initial trials its use myelofibrosis, ruxolitinib exhibited durable efficacy splenomegaly alleviation constitutional symptoms. Patients also showed weight gain improvement general...

Abstract: Ruxolitinib is an orally bioavailable, selective Janus kinase (JAK) 1 and 2 inhibitor approved for the treatment of myelofibrosis (MF), a bone marrow disease in which JAK pathway dysregulated, leading to impaired hematopoiesis immune function. By inhibiting JAK1 JAK2, ruxolitinib modulates cytokine-stimulated intracellular signaling. In phase II clinical trial patients with MF, recipients exhibited durable reductions spleen size, circulating pro-inflammatory cytokines, improvements...

Abstract Chronic graft-versus-host disease (cGVHD) remains a significant problem for patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although in vivo lymphodepletion cGVHD prophylaxis has been explored the myeloablative setting, its effects reduced-intensity conditioning (RIC) are not well described. Patients (N = 83) with hematologic malignancies underwent targeted chemotherapy followed by RIC allo-HSCT using peripheral blood cells from unrelated donors. were...

AimTo investigate the ability of two standard quality life (QOL) questionnaires – The Short Form (36-item) Health Survey (SF-36) and European Organisation for Research Treatment Cancer Quality Life Questionnaire-Core 30 (EORTC QLQ C30) to evaluate QOL in patients with chronic graft-vs-host disease (cGVHD) graded according National Institutes (NIH) consensus criteria.MethodsIn this cross-sectional study, was assessed who underwent allogeneic stem cell transplantation (allo-SCT) at University...

Chronic graft-versus-host disease (cGVHD) is the leading late complication after allogeneic hematopoietic stem cell transplantation (HSCT). Many patients receive multiple lines of systemic therapy until cGVHD resolves, but about 15% remain on treatment for more than 7 years diagnosis. This study describes clinical and biological factors who present with persisting ≥7 (persistent cGVHD). Patients persistent (n = 38) those <1 year (early cGVHD) 83) were enrolled in a prospective...

Subsequent cancer (SC) is a significant cause of morbidity and mortality in long-term survivors after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Chronic graft-versus-host disease (cGVHD) treatment-related immunosuppression have been recognized as risk factors for SC. This study sought to investigate the incidence SC patients with established cGVHD, assessed separately onset basal carcinoma (BCC) squamous (SCC)-categorized into nonmelanoma skin (NMSC)-and all cancers...
