          Abstract

          Resumen Introducción: Estudio piloto que determina el diagnóstico de sarcopenia mediante tomografía computarizada (TC) a nivel de la tercera vértebra cervical (C3) y dinamometría en pacientes con cáncer de cabeza y cuello. Comparación de la masa magra (MM) determinada mediante TC con técnicas clásicas de antropometría y dinamometría. Material y Métodos: Se analizó la MM y el tejido adiposo mediante TC a nivel de C3 en 37 pacientes oncológicos mediante Unidades Hounsfield (HU). Posteriormente, se calculó el índice musculoesquelético (IME) y se determinó la fuerza prensora de mano para la determinación de sarcopenia. Por último, se comparó el IME mediante técnicas de valoración antropométrica clásica y dinamometría. Resultados: El 59,46% de los pacientes presentaron un IME (cm2/m2) disminuido, el 64,86% dinapenia, el 54,05% sarcopenia, el 32,43% sarcopenia dentro del sobrepeso y obesidad. Por otro lado, la media de la masa grasa intermuscular fue 6,69 (3,8) cm2, y la masa grasa intramuscular 2,06 (1,11) cm2. Además, se encontró una asociación estadísticamente significativa entre la fuerza tanto en la mano fuerte (estimado=0,412; IC95% [0,219; 0,605]; p-valor<0,001) como en la mano débil (estimado=0,289; IC95% [0,123; 0,454]; p-valor<0,001) y el IME cm2/m2. Respecto a la circunferencia muscular braquial, no alcanzamos a mostrar correlación positiva. Conclusiones: Nuestro estudio muestra que en el paciente con cáncer de cabeza y cuello la prevalencia de sarcopenia es elevada. Además, la depleción muscular evaluada mediante TC a nivel de C3 y dinamometría presenta cierta correlación, por lo que, aquellos pacientes con mayor depleción muscular a nivel de C3 presentan menor funcionalidad.

          Abstract Introduction: A pilot study that tied to diagnosis sarcopenia by computed tomography (CT) at the third cervical vertebra (C3) and dynamometry in head and neck cancer patients. Comparison of the muscle mass (MM) determined by CT, with classical anthropometric measure and dynamometry techniques. Material and Methods: MM and adipose tissue were analyzed by CT at C3 level in 37 oncological patients using Hounsfield Units (HU). Consequently, skeletal muscle index (SMI) and handgrip was determined for the diagnosis of sarcopenia. Finally, SMI was compared by classical anthropometric techniques, as well as by dynamometry. Results: 59.46% of the sample presented a decreased SMI (cm2/m2), 64.86% dynapenia, 54.05% sarcopenia, and 32.43% sarcopenic obesity. On the other hand, mean intermuscular adipose tissue was 6.69 (3.8) cm2, and mean intramuscular adipose tissue 2.06 (1.11) cm2. In addition, a statistically significant association was found between SMI and strength in strong hand (estimate=0.412; 95%CI [0.219, 0.605]; p-value<0.001) and in the weak hand (estimate=0.289; 95%CI [0.123, 0.454]; p-value<0.001). Regarding the branchial muscle circumference, we did not reach to demonstrate a positive correlation. Conclusions: Our study indicates that in head and neck cancer patients there is a high prevalence of sarcopenia. In addition, muscle depletion assessed by CT scans and dynamometry have demonstrate positive correlation, and consequently, those patients with greater muscle depletion at the C3 level have less muscle functionality.

          Sarcopenia: revised European consensus on definition and diagnosis

          doi: 10.1093/ageing/afy169 In the original version of the above paper there was an error in Table 3, which shows the recommended cut-off points for ASM/height2 in women. The cut-off point was given as <6.0 kg/m2, but the correct value is <5.5 kg/m2. This has now been corrected online. The authors wish to apologise for this error.

            A practical and precise approach to quantification of body composition in cancer patients using computed tomography images acquired during routine care.

            Human body composition is important in numerous cancer research domains. Our objective was to evaluate clinically accessible methods to achieve practical and precise measures of body composition in cancer patients. Dual-energy X-ray absorptiometry (DXA)-based analysis of fat and fat-free mass was performed in 50 cancer patients and compared with bioelectrical impedance analysis (BIA) and with regional computed tomography (CT) images available in the patients' medical records. BIA overestimated or underestimated fat-free mass substantially compared with DXA as the method of reference (up to 9.3 kg difference). Significant changes in fat-free mass over time detected with DXA in a subset of 21 patients (+2.2 +/- 3.2%/100 days, p = 0.003), was beyond the limits of detection of BIA. Regional analysis of fat and fat-free tissue at the 3rd lumbar vertebra with either DXA or CT strongly predicted whole-body fat and fat-free mass (r = 0.86-0.94; p < 0.001). CT images provided detail on specific muscles, adipose tissues and organs, not provided by DXA or BIA. CT presents great practical significance due to the prevalence of these images in patient diagnosis and follow-up, thus marrying clinical accessibility with high precision to quantify specific tissues and to predict whole-body composition.

              Age-associated changes in skeletal muscles and their effect on mobility: an operational diagnosis of sarcopenia.

              Sarcopenia, the reduction of muscle mass and strength that occurs with aging, is widely considered one of the major causes of disability in older persons. Surprisingly, criteria that may help a clinician to identify persons with impaired muscle function are still lacking. Using data from a large representative sample of the general population, we examined how muscle function and calf muscle area change with aging and affect mobility in men and women free of neurological conditions. We tested several putative indicators of sarcopenia, including knee extension isometric torque, handgrip, lower extremity muscle power, and calf muscle area. For each indicator, sarcopenia was considered to be present when the measure was >2 SDs below the mean. For all four measures, the prevalence of sarcopenia increased with age, both in men and women. The age-associated gradient in prevalence was maximum for muscle power and minimum for calf-muscle area. However, lower extremity muscle power was no better than knee-extension torque or handgrip in the early identification of poor mobility, defined either as walking speed <0.8 m/s or inability to walk at least 1 km without difficulty and without developing symptoms. Optimal cutoff values that can be used in the clinical practice to identify older persons with poor mobility were developed. The findings of the study lay the basis for a cost-effective, clinical marker of sarcopenia based on a measure of isometric handgrip strength. Our findings should be verified in a longitudinal study.
