          Abstract

          Abstract Introduction: energy metabolism in cancer patients is influenced by different factors. However, the effect of antineoplastic treatment is not clear, especially in women. Objective: to evaluate resting energy expenditure (REE) by indirect calorimetry (IC) before (T0) and after (T1) first cycle period of antineoplastic therapy: radiotherapy (RT), chemotherapy (CT), and concomitant chemoradiation therapy (CRT), quality of life (QoL) and accuracy of REE were compared with international guidelines recommendations per kilogram (European Society for Clinical Nutrition and Metabolism [ESPEN]). Methods: an observational, longitudinal study was conducted in women with gynecological cancer diagnosis undergoing antineoplastic treatment: RT, CT and CRT. Weight loss, actual body weight and height were measured. REE was evaluated in T0-T1 and compared with ESPEN recommendations. Kruskal-Wallis test and Bland-Alman analysis were used to determine the agreement (± 10 % of energy predicted) of REE adjusted by physical activity (TEE) compared with ESPEN recommendations, respectively. Results: fifty-four women with cancer were included: 31.5 % (n = 17) for RT group, 31.5 % (n = 17) for CT group and 37 % (n = 20) for CRT group. REE showed statistical differences between T0 and T1 in the total population (p = 0.018), but these were not associated with anticancer therapy groups (p > 0.05). QoL had no significant changes after treatment (p > 0.05). Accuracy of 25 and 30 kcal/kg compared to TEE was less than 30 %. Conclusion: REE in women with gynecological cancer decreased after antineoplastic treatments but this is not associated with a particular antineoplastic therapy. It is needed to develop research to determine the accuracy of ESPEN recommendations with TEE estimated by IC and clinical factors in women with cancer.

          Resumen Antecedentes: el metabolismo energético en pacientes con cáncer está influenciado por diferentes factores. Sin embargo, el efecto sobre el tratamiento antineoplásico no es claro, especialmente en mujeres. Objetivo: evaluar el gasto energético en reposo (GER) mediante calorimetría indirecta (CI) antes (T0) y después (T1) del primer ciclo del tratamiento antineoplásico: radioterapia (RT), quimioterapia (QT) y quimio-radioterapia concomitante (QRT), calidad de vida (CdV) y precisión del GER con las con las recomendaciones internacionales por kilogramo de peso (European Society for Clinical Nutrition and Metabolism [ESPEN]). Métodos: se realizó un estudio longitudinal, observacional en mujeres con diagnóstico de cáncer ginecológico en tratamiento antineoplásico. Se evaluó el GER en T0 y T1. Se midieron la pérdida de peso, el peso corporal y la talla. Se usaron las pruebas de Kruskal-Wallis y el análisis Bland-Altman para determinar la concordancia (± 10 % de GER) del REE ajustado por actividad física (TEE) en comparación con las recomendaciones de ESPEN. Resultados: se incluyeron 54 mujeres con cáncer; 31,5 % (n = 17) en el grupo RT, 31,5 % (n = 17) en el de QT y 37 % (n = 20) en el de QRT. GER mostró diferencias estadísticas entre T0 y T1 en la población total (p = 0,018); no se asoció con la terapia contra el cáncer (p > 0,05). La calidad de vida no tuvo cambios significativos después del tratamiento (p > 0,05). La precisión de 25 y 30 kcal/kg en comparación con TEE fue inferior al 30 %. Conclusión: el GER en mujeres con cáncer ginecológico disminuyó después del tratamiento antineoplásico, pero no se asoció a una terapia antineoplásica en particular. Es fundamental desarrollar más investigaciones que compare las recomendaciones de ESPEN y con los valores de la CI comparando más factores clínicos para ofrecer una intervención nutricional precisa.

          ESPEN guidelines on nutrition in cancer patients

          Cancers are among the leading causes of morbidity and mortality worldwide, and the number of new cases is expected to rise significantly over the next decades. At the same time, all types of cancer treatment, such as surgery, radiation therapy, and pharmacological therapies are improving in sophistication, precision and in the power to target specific characteristics of individual cancers. Thus, while many cancers may still not be cured they may be converted to chronic diseases. All of these treatments, however, are impeded or precluded by the frequent development of malnutrition and metabolic derangements in cancer patients, induced by the tumor or by its treatment. These evidence-based guidelines were developed to translate current best evidence and expert opinion into recommendations for multi-disciplinary teams responsible for identification, prevention, and treatment of reversible elements of malnutrition in adult cancer patients. The guidelines were commissioned and financially supported by ESPEN and by the European Partnership for Action Against Cancer (EPAAC), an EU level initiative. Members of the guideline group were selected by ESPEN to include a range of professions and fields of expertise. We searched for meta-analyses, systematic reviews and comparative studies based on clinical questions according to the PICO format. The evidence was evaluated and merged to develop clinical recommendations using the GRADE method. Due to the deficits in the available evidence, relevant still open questions were listed and should be addressed by future studies. Malnutrition and a loss of muscle mass are frequent in cancer patients and have a negative effect on clinical outcome. They may be driven by inadequate food intake, decreased physical activity and catabolic metabolic derangements. To screen for, prevent, assess in detail, monitor and treat malnutrition standard operating procedures, responsibilities and a quality control process should be established at each institution involved in treating cancer patients. All cancer patients should be screened regularly for the risk or the presence of malnutrition. In all patients - with the exception of end of life care - energy and substrate requirements should be met by offering in a step-wise manner nutritional interventions from counseling to parenteral nutrition. However, benefits and risks of nutritional interventions have to be balanced with special consideration in patients with advanced disease. Nutritional care should always be accompanied by exercise training. To counter malnutrition in patients with advanced cancer there are few pharmacological agents and pharmaconutrients with only limited effects. Cancer survivors should engage in regular physical activity and adopt a prudent diet.

              Daily energy expenditure through the human life course

              Total daily energy expenditure (“total expenditure”) reflects daily energy needs and is a critical variable in human health and physiology, but its trajectory over the life course is poorly studied. We analyzed a large, diverse database of total expenditure measured by the doubly labeled water method for males and females aged 8 days to 95 years. Total expenditure increased with fat-free mass in a power-law manner, with four distinct life stages. Fat-free mass–adjusted expenditure accelerates rapidly in neonates to ~50% above adult values at ~1 year; declines slowly to adult levels by ~20 years; remains stable in adulthood (20 to 60 years), even during pregnancy; then declines in older adults. These changes shed light on human development and aging and should help shape nutrition and health strategies across the life span.
