RESUMEN
BACKGROUND: The incidence of most hematologic malignancies increases with age. Hematopoietic stem cell transplantation (HSCT) provides a potentially life-prolonging or curative option for many patients in this scenario. Limited data assessed from computed tomography (CT) images are available on muscle mass and density outcomes after HSCT. We evaluate the influence of body composition on morbidity and mortality in older adults undergoing HSCT. METHODS: Retrospective longitudinal study conducted with 50 patients ≥ 60 years old undergoing HSCT. Body composition was assessed by chest CT (CCT), and treatment-related mortality, graft-vs-host disease (GVHD), neutrophil grafting, and overall survival were analyzed. RESULTS: 148 HSCT patients were evaluated; 50 patients were eligible: 60% with autologous and 40% with allogeneic transplantation. Body mass index in patients was (female: 26.9 ± 4.7 kg/m2 ; male: 30.1 ± 4.9 kg/m2 ) - autologous and, (female: 24.3 ± 5.1 kg/m2 ; male: 26.4 ± 2.0 kg/m2 ) - allogeneic. In the autologous group, we found a positive association between age and death risk, with 63.5% increased risk of death (P = 0.006), and also Karnofsky Performance Score, with a 11.9% decrease in death risk (P < 0.001). A negative association between muscle radiodensity and death risk was observed in patients who received an allogeneic transplantation, with a risk decrease of 20.1% (P = 0.032). We found a positive association between the fourth thoracic vertebra muscle area and radiodensity and risk of acute GVHD (P = 0.028). CONCLUSION: Body composition assessed by CCT showed the importance of radiodensity for better prognosis.

The Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Elderly was elaborated by nutritionists, nutrologists and hematologists physicians from 15 Brazilians reference centers in hematopoietic stem cell transplantation, in order to emphasize the importancy of nutritional status and the body composition during the treatment, as well as the main characteristics related to patient's nutritional assessment. Establishing the consensus, we intended to improve and standardize the nutritional therapy during the hematopoietic stem cell transplantation. The Consensus was approved by the Brazilian Society of Bone Marrow Transplantation.

RESUMO O Consenso Brasileiro de Nutrição em Transplante de Células-Tronco Hematopoiéticas: Idoso foi elaborado com a participação de nutricionistas, médicos nutrólogos e médicos hematologistas de 15 centros brasileiros referência em transplante de células-tronco hematopoiéticas, com o objetivo de salientar a importância do estado nutricional e da composição corporal durante o tratamento, bem como as principais características relacionadas à avaliação nutricional do paciente. As intenções, ao se estabelecer o consenso, foram aprimorar e padronizar a terapia nutricional durante o transplante de células-tronco hematopoiéticas. O consenso foi aprovado pela Sociedade Brasileira de Transplante de Médula Óssea.
