Inflammation, but not skeletal muscle index, is associated with coronavirus disease 2019 mortality in patients with cancer.

BACKGROUND & AIMS: Patients with cancer and coronavirus disease 2019 (COVID-19) have characteristics that can cause the most severe forms of the disease and higher mortality. We aimed to assess the association between computed tomography (CT)-derived muscle abnormalities, anthropometric parameters, inflammation, and mortality in patients with cancer and COVID-19. METHODS: This retrospective study included patients with cancer and COVID-19 admitted between March 1st and December 31st, 2020. All information was collected from medical records (clinical and nutritional parameters, serum albumin, and C-reactive protein [CRP]). Weight loss and body mass index (BMI) were assessed using Global Leadership Initiative on Malnutrition phenotypic criteria. Skeletal muscle index (SMI) and skeletal muscle radiodensity (SMD) at the fourth thoracic vertebra level were assessed using computed tomography scans. RESULTS: This study included 80 patients (61% men, mean age: 58 ± 17 years). Of the patients analyzed, 49% had weight loss >5%, and 14% had low BMI. The median length of hospital stay was 7 (interquartile range: 4-14 days), 27% needed mechanical ventilation, 34% died as a direct consequence of COVID-19 infection and 15% to complications associated with cancer condition. In multivariate logistic regression analysis, low SMI was associated with increased in-hospital mortality [odds ratio (OR): 4.81; 95% confidence interval (95% CI): 1.63; 14.2; p = 0.005), while CRP was associated with COVID-19-related mortality (OR: 1.08; 95% CI: 1.01; 1.15, p = 0.018). CONCLUSION: SMI independently predicts in-hospital mortality in patients with cancer and COVID-19. Additionally, an independent association was observed between CRP and mortality specifically related to COVID-19.

Nutritional status at hospital admission and prediction of clinical outcomes in children and adolescents with cancer: Results of the Brazilian survey on oncological nutrition in paediatrics.

BACKGROUND: Changes in nutritional status are recognised as predictors of unfavourable outcomes in children and adolescents with cancer, particularly in developing countries. There have been no studies on children and adolescents with cancer from every region of Brazil or on the impact of nutritional status on clinical outcomes. The aim of this study is to assess the association between the nutritional status of children and adolescents with cancer and the prediction of clinical outcomes. METHODS: This was a longitudinal, multicentre, hospital-based study. An anthropometric nutritional assessment was performed, and the Subjective Global Nutritional Assessment (SGNA) was administered within 48 h of admission. Seven hundred and twenty-three patients (aged 2-18 years) were included in the sample, undergoing cancer treatment. They were recruited in 13 reference centres in the five macro-regions of Brazil between March 2018 and August 2019. The outcomes evaluated were readmission within 30 days and death within 60 days of admission. To identify predictors of 60-day survival, Cox regression and log-rank statistics were used to compare Kaplan-Meier curves between the strata. RESULTS: About 36.2% (n = 262) of the samples were malnourished according to the SGNA. Severe malnutrition by the SGNA (relative risk [RR] = 8.44, 95% confidence interval [CI]: 3.35-21.3, P = 0.001) and living in the North region (RR = 11.9, 95% CI: 3.34-42.7, P = 0.001) were associated with the poorest survival. The North (RR = 5.77, 95% CI: 1.29-25.8, P = 0.021), Northeast (RR = 1.46, 95% CI: 1.01-2.11, P = 0.041), Midwest (RR = 0.43, 95% CI: 0.20-0.095, P = 0.036), age group 10-18 years (RR = 0.65, 95% CI: 0.45- 0.94, P = 0.022) and haematologic malignancy (RR = 1.52, 95% CI: 1.10-2.10, P = 0.011) were predictors of readmission within 30 days. CONCLUSIONS: The prevalence of malnutrition was high and related to death. These results highlight the need to use the SGNA in clinical practice alongside classic anthropometric methods for the diagnosis of malnutrition, and the need to standardise care across all Brazilian regions, which should include nutritional care for children and adolescents with cancer.

Association between functional aspects and health-related quality of life in patients with colorectal cancer: can handgrip strength be the measure of choice in clinical practice?

PURPOSE: We aimed to investigate the association between handgrip strength (HGS) and health-related quality of life (HRQoL) in patients with colorectal cancer (CRC). A cross-sectional study was conducted including CRC patients. METHODS: We performed an assessment of aspects of functional health using the criteria of frailty phenotype (defined by Fried et al., 2001), sarcopenia (defined by the European Working Group on Sarcopenia in Older People 2, 2018) and by HGS, which measures muscle strength using a manual dynamometer. HRQoL was assessed using the EORTC questionnaire QLQ-C30. Analyses of variance and multivariate linear regression were used to compare frailty, sarcopenia, and HGS with HRQoL. RESULTS: A total of 142 patients were included (age 62.7 ± 11.4 years; 56.3% women; 18.3% of patients with frailty; 9.9% with sarcopenia, and 15.5% had low HGS). After adjusting for sociodemographic, clinical, and nutritional variables, the regression analysis showed that frailty and sarcopenia were associated with worse HRQoL. Low HGS was associated with worse HRQoL in patients with CRC regardless of both frailty components (global health status: B = - 13.4, p = 0.004; physical function: B = - 10.4, p = 0.006; emotional function: B = - 18.1, p = 0.041; fatigue: B = 9.1, p = 0.027; dyspnea: B = 10.7, p = p = 0.024; appetite loss: B = 12.4, p = 0.041) and sarcopenia components (global health status: B = - 13.2, p = 0.004; physical function: B = - 15.0, p = 0.001; emotional function: B = - 25.1, p = 0.006; fatigue: B = 15.2, p = 0.007; pain: B = 18.7, p = 0.024, dyspnea: B = 11.4, p = 0.017). CONCLUSION: We concluded that HGS was positively associated with HRQoL in patients with CRC and may initially be the variable of choice in clinical practice, which is associated with HRQoL.

Predictive validity of GLIM malnutrition diagnosis in patients with colorectal cancer.

BACKGROUND: Considering that the validation of the Global Leadership Initiative on Malnutrition (GLIM) remains unclear in patients with colorectal cancer, the present study aimed to assess the agreement, accuracy, sensitivity, specificity, and prognostic effect of the GLIM on survival when compared with the Patient-Generated Subjective Global Assessment (PG-SGA). METHODS: Patients with colorectal cancer who were scheduled to undergo a routine abdominal computed tomography (CT) scan were recruited. Using the GLIM two-step approach, the patients were first screened for malnutrition by using the PG-SGA Short Form (score ≥3). The malnutrition diagnosis was based on the etiologic (disease burden [cancer] or reduced food intake) and phenotypic GLIM criteria, including weight loss, body mass index, and skeletal muscle index at the third lumbar vertebra when using the CT scans. The food intake was assessed by the PG-SGA. RESULTS: This study included 191 patients (age, 60.5 ± 11.3 years; 57% men), and 23% and 32% were malnourished according to the GLIM and the PG-SGA, respectively. The GLIM revealed fair sensitivity (64%), good agreement (kappa = 0.65), specificity (96%), and diagnostic accuracy for detecting malnutrition (area under the receiver operating characteristic curve = 0.80; 95% CI, 0.72-0.88) when compared with the PG-SGA. The malnutrition value according to the GLIM and the PG-SGA was associated with short-term survival. However, only the PG-SGA was associated with long-term survival. CONCLUSIONS: Although showing fair sensitivity, the GLIM had good agreement, specificity, and diagnostic accuracy for malnutrition detection and was an independent predictor of short-term survival in patients with colorectal cancer.

Performance of subjective global nutritional assessment in predicting clinical outcomes: Data from the Brazilian survey of pediatric oncology nutrition.

BACKGROUND: Methods for assessing nutritional status in children and adolescents with cancer is a difficult in clinical practice. The study aimed to evaluate the performance of Subjective Global Nutritional Assessment (SGNA) in predicting clinical outcomes in children and adolescents with cancer in Brazil. METHODS: This was a prospective cohort multicenter study. It was included 723 children and adolescents with cancer aged 2-18 years between March 2018 and August 2019. Nutritional assessment was performed according to World Health Organization recommendations and using SGNA within 48h of hospitalization. Unplanned readmission, length of hospital stay, and post-discharge death were analyzed. Cohen's kappa coefficient was used to ascertain the agreement between body mass index for age (BMI/A) and SGNA. The sensitivity, specificity, positive and negative predictive values, and accuracy of SGNA were estimated. Odds ratios (ORs) with 95% confidence intervals (CIs) were evaluated using multiple logistic regression. RESULTS: The mean patient age was 9.4 ± 4.9 years. SGNA showed that 29.7% (n = 215) and 6.5% (n = 47) patients had moderate and severe malnutrition, respectively. Considering the concurrent validity criterion, SGNA had an OR (95% CI) of 6.8 (3.1-14.9) for predicting low and very low weight for age at admission, with a sensitivity and specificity of 72.4% (59%-82.1%) and 72% (64.2%-78.9%), respectively. SGNA could predict death in children with severe/moderate malnutrition, with an accuracy of 63.8% (63%-65.1%). Logistic multivariate analysis showed that the adjusted effect of death; hematological tumor; living in the northeast, southeast, and midwest regions of Brazil; and older age was associated with malnutrition according to SGNA. CONCLUSION: Based on concurrent validity between SGNA and anthropometry, SGNA performed well and had a good ability to predict death in Brazilian children with cancer.

Impact of Nutritional Status on Survival in Head and Neck Cancer Patients After Total Laryngectomy.

Malnutrition is an important prognostic indicator of laryngeal squamous cell carcinoma. Retrospective study with head and neck cancer patients who underwent total laryngectomy. 243 patients of both sex were evaluated. The univariate analyses demonstrated an increased risk of death for the patients with greater weight loss, hypoalbuminemia, radiotherapy as an initial treatment, salvage surgery, and radical neck dissection. In a Multivariate Cox regression, older age (p = 0.03, 95% confidence interval [CI] 1.003-1.06, hazard ratio [HR] 1.029), Nutritional Risk Index ≤100 (p = 0.008, 95% CI 1.18-3.12, HR 1.921) and adjuvant radiotherapy (p = 0.029, 95% CI 0.31-3.12, HR 0.544) demonstrated prognostic significance in survival. Nutritional status is a modifiable variable and these findings highlight the need to adoption of simple nutritional assessment methods routinely during the treatment of head and neck cancer patients, in order to help improve prognosis after surgery.

Phase angle as a marker for muscle abnormalities and function in patients with colorectal cancer.

BACKGROUND AND AIMS: Considering the applicability of phase angle (PhA) as a marker of muscle mass and function, we aimed to investigate whether PhA is a predictor of muscle abnormalities and function in patients with cancer. METHODS: In a sample of patients with colorectal cancer (CRC), PhA was obtained from measurements of resistance and reactance from bioelectrical impedance analysis. Computerized tomography imaging at the third lumbar vertebra was used to evaluate muscle abnormalities by quantifying skeletal muscle index (SMI) and skeletal muscle radiodensity (SMD). Muscle function was assessed by handgrip strength (HGS) and gait speed (GS). RESULTS: This cross-sectional study included 190 participants (X±SD), mean age 60.5 ± 11.3 years; 57% men; 78% had cancer stages III to IV. PhA was highly correlated with SMI (r = 0.70) and moderately correlated with HGS (r = 0.54). PhA explained 48% of the SMI variability (R2 = 0.485), 21% of the SMD variability (R2 = 0.214), 26% of HGS (R2 = 0.261) and 9.8% of GS (R2 = 0.098). In the multivariate model adjusted for age, sex, body mass index, performance status, comorbidities and cancer stage, 1-degree decrease in PhA was associated with low SMI (Odds Ratio (OR) = 6.56, 95% CI: 2.90-14.86) and with low SMI and HGS combined (OR = 11.10, 95% CI: 2.61-47.25). In addition, Receiving Operating Characteristics curve analysis showed that PhA had a good diagnostic accuracy for detecting low SMI, low SMI and SMD combined, low SMD and HGS and low SMI and HGS combined (AUC = 0.81, 95% CI: 0.74-0.88; AUC = 0.88, 95% CI: 0.81-0.95; AUC = 0.80, 95% CI: 0.70-0.91; AUC = 0.82, 95% CI: 0.74-0.89; respectively). CONCLUSIONS: PhA was a predictor of muscle abnormalities and function and had a good diagnostic accuracy for detecting low muscle mass, low muscle mass and radiodensity, low muscle radiodensity and strength, and low muscle mass and strength in patients with CRC.

Segundo o Índice de Massa Corporal/Idade (IMC/I), magreza e magreza acentuada totalizaram 13%, risco de sobrepeso, sobrepeso e obesidade apresentaram uma prevalência de 26,7% de 2 a 5 anos; 24,9% de 5 a 10 anos; e 25,7% de 10 a 19 anos. Conclusão: Evidenciou-se alta prevalência de inadequação nutricional pela ANSGP, sugerindo que a desnutrição pode ser subdiagnosticada quando utilizado somente o IMC/I, fortalecendo a necessidade de utilização de métodos complementares na avaliação nutricional de crianças com câncer

Introduction: Malnutrition is found in children with cancer and is associated with negative clinical outcomes. Objective: To describe the prevalence of inadequate nutritional status of children and adolescents with malignant neoplasm at hospital admission in childhood cancer reference centers in Brazil. Method: Cross-sectional study nested in a multicenter, hospital-based cohort study. The probabilistic sample was carried out in two stages in each stratum by macro-region using the probability method proportional to the size with one year of collection in each institution. Clinical, anthropometric, body composition data and the Pediatric Subjective Global Nutritional Assessment (SGNA) questionnaire were collected from 13 reference institutions within 48 hours of hospital admission, from March 2018 to August 2019. Results: The study totaled 723 patients in the 5 regions of Brazil. The prevalence of moderate and severe malnutrition was 25.9% in the age group of 2 to 5 years, 40.1% in 5 to 10 years and 39.7% in 10 to 19 years, according to the SGNA. According to the Body Mass/Age Index (BMI/I), thinness and marked thinness totaled 13%, risk of overweight, overweight and obesity showed a prevalence of 26.7% from 2 to 5 years, 24.9% from 5 to 10 years and 25.7% from 10 to 19 years. Conclusion: There was a high prevalence of nutritional inadequacy by the SGNA, suggesting that malnutrition can be underdiagnosed when using only the BMI/I, strengthening the need to use complementary methods in the nutritional assessment of children with cancer

Frailty is associated with myosteatosis in obese patients with colorectal cancer.

BACKGROUND & AIMS: We aimed to explore the determinants of muscle fat infiltration and to investigate whether myosteatosis, assessed as muscle fat infiltration percentage (%MFI) and muscle attenuation from computed tomography (CT), is associated with frailty in a group of patients with colorectal cancer (CRC). METHODS: Cross sectional study including CRC patients. CT scan of the third lumbar vertebra was used to quantify body composition and the degree of %MFI (reported as percentage of fat within muscle area). Frailty was defined by Fried et al. (2001) as the presence of more than 3 criteria: unintentional weight loss, self-reported exhaustion, weakness (low handgrip strength), slow walking speed (gait speed) and low physical activity. Obesity was defined according to sex-and-age-specific body fat percentage (%BF) cutoff. RESULTS: A sample of 184 patients (age 60 ± 11 years; 58% men; 29% of patients with frailty) was studied. The sample was divided according to tertiles of MFI% (1st tertile 0 to 2.89%, n = 60; 2nd tertile ≥ 3.9-8.19%, n = 64; 3rd tertile ≥ 8.2-26%, n = 60). Age, females, body mass index, %BF, subcutaneous and visceral adipose tissue and the proportion of patients with frailty were significantly higher in the 3rd %MFI tertile. Phase angle and muscle attenuation were significantly lower in the 3rd %MFI tertile. The determinants of %MFI (r2 = 0.49), which was log transformed due to its normal distribution, were %BF (ß = 0.54; eß = 1.72; 95% CI: 0.032 to 0.051; P < 0.01), age (ß = 0.34; eß = 1.40; 95% CI: 0.016 to 0.032; P < 0.01) and gait speed (ß = -0.12; eß = 0.87; 95% CI: -0.84 to -0.001; P = 0.049). In addition, in obese patients (n = 74) presenting 4 or 5 frailty criteria increased the chance of having higher %MFI and lower muscle attenuation, after adjustment for sex, age and comorbidities when compared to none or 1 criteria. CONCLUSIONS: In a sample of CRC patients, %BF and gait speed were the determinants of %MFI. In addition, markers of myostetatosis were associated with frailty in the obese patients.

Comparative Analysis Between Computed Tomography and Surrogate Methods to Detect Low Muscle Mass Among Colorectal Cancer Patients.

BACKGROUND: We aimed to evaluate the agreement between computed tomography (CT) and surrogate methods applied in clinical practice for the assessment of low muscle mass. In addition, we assessed the association between different muscle-assessment methods and nutrition status, as well as the prognostic value of low muscle mass on survival in patients with colorectal cancer (CRC). METHODS: This is a cohort including 188 CRC patients with 17 months' follow-up (interquartile range: 12-23 months) for mortality. Low muscle mass was evaluated by corrected mid-upper arm muscle area (AMAc) and calf circumference, skeletal muscle mass by bioelectrical impedance analysis (BIA), muscle deficit by physical examination with the Patient-Generated Subjective Global Assessment (PG-SGA), and lumbar muscle cross-sectional area by CT (reference method). RESULTS: The prevalence of low muscle mass ranged from 9.6% to 54.3% according to the method used. The physical examination had the highest κ coefficient compared with CT. Low muscularity was associated with the presence of malnutrition, lower body fat, and low phase angle. The Cox regression models-adjusted for age, sex, and treatment 3 months before study inclusion-showed that severe muscle loss measured by BIA and CT and low muscle mass measured by PG-SGA predicted higher mortality rates. CONCLUSIONS: Compared with CT, the physical examination had the best agreement to assess low muscle mass. Low muscle mass assessed by PG-SGA, BIA, and CT showed similar prognostic values for survival.

Postoperative complication rate and survival of patients with gastric cancer undergoing immunonutrition: A retrospective study.

OBJECTIVES: This study aimed to evaluate the effect of preoperative immunonutrition on the rate of postoperative complication and survival of patients with gastric cancer. METHODS: A retrospective cohort was formed after data collection of patients hospitalized with gastric cancer. Postoperative complications classified according to the Clavien-Dindo classification system, length of hospital stay, readmissions, and rates of survival at 6 mo, 1 y, and 5 y were analyzed. A χ2 or Fisher's exact test, Student or Mann-Whitney t test, and Kaplan-Meier and Cox regressions were used in the statistical analysis. RESULTS: A total of 164 patients were included in the study, with 56 patients assigned to the immunonutrition group and 108 to the conventional group. There were no significant differences in postoperative complications between the immunonutrition and conventional groups (51.8% versus 58.3%; P = 0.423). The most frequent complications were fistula and surgical wound infection. Length of hospital stay did not differ between the groups (median of 7.0 d: P = 0.615) and the presence of readmissions did not differ either (12.5% versus 15.7%; P = 0.648). In the multivariate Cox regression, in a pooled model for group, age, sex, body mass index, Charlson comorbidity index, staging, neoadjuvant chemotherapy, and type of surgery, there was a significant difference in survival rates at 6 mo (P = 0.011), 1 y (P = 0.006), and 5 y (P < 0.001). CONCLUSIONS: Preoperative immunonutrition in patients with gastric cancer did not reduce postoperative complications or length of hospital stay. More studies are needed to confirm the benefit of immunonutriton supplementation for overall survival when associated with other protective factors.

Patient-generated subjective global assessment predicts cachexia and death in patients with head, neck and abdominal cancer: A retrospective longitudinal study.

BACKGROUND & AIMS: Cancer is a complex disease, with poor prognosis when associated with malnutrition. This condition can lead to Cancer Cachexia (CC), a syndrome characterized by loss of muscle mass with or without fat loss, often associated with higher risk of death. Although there are recommended screening tools to assess nutritional status in cancer patients, such as Patient-Generated Subjective Global Assessment (PG-SGA), little is known about CC prediction. The aim was to investigate the association between nutritional status of patients with head, neck and abdominal cancer, assessed by PG-SGA at the day of hospitalization, with CC, hospitalization time and death. METHODS: This is a retrospective longitudinal study, where we collected data of 97 patients about PG-SGA nutritional classification, anthropometry, gender, age, cachexia diagnosis and death. RESULTS: PG-SGA classification was strongly associated with all the anthropometric measures (p < 0.0001). According to PG-SGA classification, 30.61% (n = 15) of patients in group A developed pre-cachexia; 38.24% in group B developed CC (n = 13); and 60% (n = 9) in group C developed refractory cachexia (p < 0.0001). Death rate was 24.49% (n = 12), 54.55% (n = 18) and 80% (n = 12) in groups A, B and C, respectively (p < 0.0001). PG-SGA had good sensibility (89.5%) and accuracy (72%) for CC, and also good specificity (75.51%) and accuracy (69%) for death. CONCLUSIONS: PG-SGA demonstrated a significative association with the variables measured and was able to predict CC and death. This, in addition to its simple applicability, suggests that PG-SGA can be a useful tool to screen cancer patients for CC establishment and death risk.

Factors Associated with Sarcopenia in Patients with Colorectal Cancer.

Introduction; Sarcopenia are frequently observed in cancer patients and was associated with poor prognosis. Objectives; to determine the association of nutritional status, body composition, and clinic parameters with sarcopenia in patients with colorectal cancer (CRC). Methods; We conducted a cross-sectional study of 197 patients with CRC. The sarcopenia elements, including lumbar skeletal muscle index (SMI), handgrip strength, and gait speed were measured. The SMI was assessed by computed tomography at third lumbar vertebra. Phase angle (PA), serum albumin (SAlb), muscle attenuation (MA), and the scored patient-generated subjective global assessment (PG-SGA) were also evaluated. Univariate and multivariate analysis of factors associated with sarcopenia were performed. Results; Sarcopenia was present in 29 of 195 patients (15%) and was significantly correlated with advance age, lower body mass index (BMI), SAlb, PA, MA, higher PG-SGA score, and malnutrition (PG-SGA B). In univariate analysis, age, BMI, SAlb, PA, MA, PG-SGA score, and malnutrition (PG-SGA B) were associated with sarcopenia. Multivariable analysis revealed that BMI, SAlb, PA, MA, and PG-SGA score were independent predictors of sarcopenia. Conclusion; BMI, SAlb, PA, MA, and PG-SGA score were independent predictors of sarcopenia in patients with CRC.
