Filter by:Patients undergoing hematopoietic cell transplantation (HSCT) receive high doses of chemotherapy with or without radiotherapy to eradicate the underlying disease, which induces a series of adverse effects, including in the oral cavity. Among the most common oral lesions is oral mucositis (OM), which has been associated with greater morbidity and important biological and economic impact.Currently, photobiomodulation (PBM) with intraoral application has been recommended for the prevention of OM, however, few studies have evaluated the impact of its extraoral use.
Allogeneic hematopoietic cell transplantation (HCT) is an important therapeutic strategy for many malignant and benign hematologic diseases. Haploidentical HCT has been increasingly used in patients lacking a HLA-matched donor due to its prompt availability, possibly lower cost and results comparable with other donor types. Graft-versus-host disease (GVHD) is the main cause of morbidity and mortality after HSCT, and prophylactic strategies are routinely used. In the context of haploidentical HCT, posttransplant cyclophosphamide plus cyclosporine and mycophenolate mofetil (MMF) is the most common platform used in Brazil. Data comparing MMF and methotrexate (MTX) as GVHD prophylaxes have proved controversial in other donor types, yet some large studies have showed that MTX is associated with lower risk of GVHD and improved long-term outcomes. Moreover, it is known that MMF is a potent inhibitor of natural killer (NK) cells, possibly interfering with the graft-versus-leukemia effect in haploidentical HCT. Given the possible advantages and the absence of consistent evidence regarding safety, efficacy and ideal dosage of MTX as GVHD prophylaxis in this setting, we propose a phase I / II study evaluating this drug in adult patients with hematologic malignancies undergoing haploidentical HCT with posttransplant cyclophosphamide.
This is a single center, cross-sectional, non-interventional study aimed at the nutritional intake of long-term health of allogeneic or autologous hematopoietic stem cell transplant (HSCT) survivors.
