    ABSTRACT: Various dogmata have been broken as a consequence of the evolution of knowledge in the area of allogeneic haematopoietic stem cell (HSC) transplantation. The following is now clear: for the successful engraftment of allogeneic HSC, bone marrow ablation of the recipient is not required; HSCs create their own space through graft-versus-host reactions; several malignancies can be eradicated by the graft-versus-tumour effect; HSC allografting can be conducted on an out-patient basis; HSC allografting can be done in aged or debilitated individuals; HSC allografting can be achieved without transfusion of blood products; and the costs of the allografting procedures can be substantially diminished. Despite the fact that HSC allografting with reduced intensity conditioning may be related to several disadvantages, such as mixed chimaerism and relapse of the malignancy, breaking these dogmata has resulted in availability of HSC allografting to a larger number of individuals worldwide, thus offering true curative therapeutic options to patients who otherwise would not qualify to be given these opportunities.

    ABSTRACT: BACKGROUND: The impact of obesity on hematopoietic stem cell transplantation (HSCT) outcome remains controversial and has been considered a relative contraindication for the procedure. We investigated the influence of Body Mass Index (BMI) on the clinical course of adults undergoing an ambulatory HSCT after a non-myeloablative conditioning regimen. METHODS: Adults with hematologic diseases undergoing an autologous or allogeneic HSCT after reduced intensity conditioning (RIC) and supported exclusively with enteral nutrition (EN) were studied. BMI and body fat were sequentially determined. Patients were divided into three BMI subgroups: underweight; normal, and overweight/obese. RESULTS: Seventy-seven patients with a median follow-up of 21months were evaluated. Fourteen (18.2%) were underweight, 21 (27.3%) had a normal weight, and 42 (54.5%) were overweight/obese. A significant weight loss was observed among all three weight groups after HSCT (P=0.014). No correlation was found between time to engraftment and BMI (P=0.91), serum albumin (P=0.387), and fasting glucose (P=0.64), nor between BMI and acute (P=0.456) or chronic (P=0.209) graft versus host disease (GVHD). On multivariate analysis a higher overall survival (OS) was documented for obese patients (P=0.037). DISCUSSION: A BMI >30/kg/m(2) was independently associated with a higher survival rate after HSCT. Obese patients should not be excluded as transplant candidates based only on this parameter.
