We aimed to investigate the prevalence of sarcopenia using new diagnostic criteria and association of sarcopenia with cardiopulmonary function and physical activity (PA) in preoperative lung cancer patients. The data of 614 patients were obtained from the CATCH-LUNG cohort study. Patients were classified into three groups-normal (<i>n</i> = 520), pre-sarcopenia (<i>n</i> = 60, low skeletal muscle mass index only), and sarcopenia (<i>n</i> = 34, low SMI and strength). Cardiopulmonary function was ...[more]

Project description:BackgroundDespite the associations of both preoperative sarcopenia and physical performance with post-operative mortality in non-small-cell lung cancer (NSCLC), there have been no comprehensive studies of the impact of physical status on prognosis. This study was performed to investigate the prognostic significance of preoperative sarcopenia and physical performance in NSCLC.MethodsThis retrospective cohort study was performed in NSCLS patients undergoing curative lung resection at a university hospital between January 2014 and December 2017. The patients were divided into four groups according to the skeletal muscle index [sarcopenia (lowest sex-specific tertile) and non-sarcopenia] and 6 min walking distance (6MWD) [short distance (<400 m) and long distance (≥400 m)]. Sarcopenia was assessed by preoperative cross-sectional areas of right and left paraspinous muscles at the level of the 12th thoracic vertebra from computed tomography images, and physical performance was determined by preoperative 6MWD. The primary and secondary endpoints were post-operative overall survival (OS) and disease-free survival (DFS).ResultsThe 587 patients [mean age: 68.5 ± 8.8 years, 399 men (68%)] included in the study were divided into the non-sarcopenia/long-distance group (58%), sarcopenia/long-distance group (26%), non-sarcopenia/short-distance group (9%), and sarcopenia/short-distance group (7%). A total of 109 (18.6%) deaths and 209 (35.6%) combined endpoints were observed over a mean follow-up of 3.1 ± 1.3 years. After adjusting for other covariates, the sarcopenia/short-distance group showed significant associations with shorter OS (hazard ratio, 3.38; 95% confidence interval, 1.79-6.37; P < 0.001) and DFS (hazard ratio, 2.11; 95% confidence, 1.27-3.51; P = 0.004) compared with the non-sarcopenia/long-distance group on multivariate analyses. Although not significant, adding skeletal muscle index and 6MWD to the pre-existing risk model increased the area under the curve on time-dependent receiver operating characteristic curve analysis for OS and DFS, except within 2 years of surgery.ConclusionsThe presence of both preoperative paraspinous muscle sarcopenia and short distance in 6MWD had an adverse effect on post-operative prognosis in patients with NSCLC, suggesting that preoperative assessment of thoracic sarcopenia and physical performance may be useful for risk stratification of surgical candidates with potential for targeted interventions.

Project description:This retrospective observational study aimed to evaluate whether preoperative sarcopenia, assessed by CT imaging, was associated with postoperative clinical outcomes and overall survival in patients that underwent liver resections. Patients operated on between January 2014 and February 2020 were included. The skeletal muscle index (SMI) was measured at the level of the third lumbar vertebra on preoperative CT scans. Preoperative sarcopenia was defined based on pre-established SMI cut-off values. The outcomes were postoperative morbidity, length of hospital stay (LOS), and overall survival. Among 355 patients, 212 (59.7%) had preoperative sarcopenia. Patients with sarcopenia were significantly older (63.5 years) and had significantly lower BMIs (23.9 kg/m2) than patients without sarcopenia (59.3 years, p < 0.01, and 27.7 kg/m2, p < 0.01, respectively). There was no difference in LOS (8 vs. 8 days, p = 0.75), and the major complication rates were comparable between the two groups (11.2% vs. 11.3%, p = 1.00). The median overall survival times were comparable between patients with sarcopenia and those without sarcopenia (15 vs. 16 months, p = 0.87). Based on CT assessment alone, preoperative sarcopenia appeared to have no impact on postoperative clinical outcomes or overall survival in patients that underwent liver resections. Future efforts should also consider muscle strength and physical performance, in addition to imaging, for preoperative risk stratification.

Project description:BackgroundLung transplant (LTX) can provide a survival benefit and improve physical function for selected patients with advanced pulmonary disease. Sarcopenia is a systemic muscle-failure that can be found in a variety of life stages and disabilities. In this study, we follow the evolution of each variable defined in sarcopenia and the outcomes in LTX recipients with post-transplant sarcopenia.MethodsPatients who underwent LTX at Tohoku University Hospital between 2013 and 2018 were consecutively included in the retrospective cohort study, with follow-up to 2019. Sarcopenia was defined by low muscle mass (the cross-sectional area (CSA) of erector spinae muscle (ESM) in thoracic CT with a threshold < 17.24 cm2/m2) and either low muscle strength (hand-grip with a threshold of < 26 kg in males and of < 18 kg in females) or physical performance (6-min walk distance with a threshold < 46.5% of predicted distance).ResultsFifty-five recipients were included into the study, of whom 19 patients were defined as sarcopenic and 36 as non-sarcopenic. The muscle mass improved after transplant in both sarcopenic and non-sarcopenic individuals: the median ESM-CSA enlarged from 17.25 cm2/m2 in 2 months post-LTX to 18.55 cm2/m2 in 12 months (p < 0.001) and 17.63 cm2/m2 in 36 months (p < 0.001) in non-sarcopenic individuals, while in sarcopenic patients it improved from 13.36 cm2/m2 in 2 months to 16.31 cm2/m2 in 12 months (p < 0.005) and 18.01 cm2/m2 in 36 months (p < 0.001). The muscle mass in sarcopenia substantially recovered to close to non-sarcopenic conditions within 36-months (p < 0.001 in 2 months and p = 0.951 in 36 months). Accordingly, muscle strength and physical performance in both groups improved over time. No difference in survival was seen in both groups (Log-rank p = 0.096), and sarcopenia was not associated with an overall hazard of death (p = 0.147). There was no difference in the cumulative incidence of chronic lung allograft dysfunction between patients with or without sarcopenia (Log-rank p = 0.529).ConclusionsEven patients with post-transplant sarcopenia have a chance to recover physical function to levels close to those without sarcopenia several years post LTX.

Project description:ObjectivesTo evaluate the independent association between symptom burden and physical function impairment in older adults with cancer.DesignCross-sectional.SettingTwo university-based geriatric oncology clinics.ParticipantsPatients with cancer aged 65 years or older who underwent evaluation with geriatric assessment (GA).MeasurementsSymptom burden was measured as a summary score of severity ratings (range = 0-10) of 10 commonly reported symptoms using a Clinical Symptom Inventory (CSI). Functional impairment was defined as the presence of one or more impairments of instrumental activities of daily living (IADLs), any significant physical activity limitation on the Medical Outcomes Survey (MOS), one or more recent falls in the previous 6 months, or a Short Physical Performance Battery (SPPB) score of 9 or less. Multivariate analysis evaluated the association between symptom burden and physical function impairment, adjusting for other clinical and sociodemographic variables.ResultsFrom 2011 to 2015, 359 patients with cancer and a median age of 81 years (range = 65-95 y) consented. The mean CSI score was 23.2 ± 20.5 with an observed range of 0 to 90. Patients in the highest quartile of symptom burden (N = 91; CSI score 52 ± 13) had a higher prevalence of IADL impairment (91% vs 51%), physical activity limitation (93% vs 65%), falls (55% vs 21%), and SPPB score of 9 or less (92% vs 69%) (all P values <.01) when compared with those in the bottom quartile (N = 81; CSI score: 2 ± 2). With each unit increase in CSI score, the odds of having IADL impairment, physical activity limitations, falls, and SPPB scores of 9 or less increased by 4.8%, 4.4%, 2.9%, and 2.5%, respectively (P < .05 for all results).ConclusionsIn older patients with cancer, higher symptom burden is associated with functional impairment. Future studies are warranted to evaluate if improved symptom management can improve function in older cancer patients. J Am Geriatr Soc 67:998-1004, 2019.

Project description:BackgroundSarcopenia, as measured at the 3rd lumbar (L3) level, has been shown to prognosticate survival in cancer patients. However, many patients with early-stage non-small cell lung cancer (NSCLC) do not undergo abdominal imaging. We hypothesized that preoperative thoracic sarcopenia is associated with survival in patients undergoing lung resection for early-stage NSCLC.MethodsPatients who underwent anatomic resection for NSCLC between 2010-2019 were retrospectively identified. Exclusion criteria included induction therapy, less than 90 days of follow-up, and absence of computed tomography (CT) imaging. Cross sectional skeletal muscle area was calculated at the fifth thoracic vertebra (T5), twelfth thoracic vertebra (T12), and L3 level. Gender-specific lowest quartile values and previously defined values were used to define sarcopenia. Overall survival and disease-free survival were assessed using the Kaplan-Meier method.ResultsOverall, 221 patients met inclusion criteria with a median body mass index (BMI) of 26.5 kg/m2 [interquartile range (IQR), 23.3-29.9 kg/m2], age of 69 years (IQR, 62.4-74.9 years), and follow-up of 46.9 months (IQR, 25.0-70.7 months). At the T5 level, sarcopenic males demonstrated worse overall survival [median 41.0 (IQR, 13.8-53.7) vs. 42.0 (IQR, 23.1-55.1) months, P=0.023] and disease-free survival [median 15.8 (IQR, 8.4-30.78) vs. 34.8 (IQR, 20.1-50.5) months, P=0.007] when compared to non-sarcopenic males. There was no difference in survival between sarcopenic and non-sarcopenic females when assessed at T5. Sarcopenia at T12 or L3 was associated with worse overall survival (P<0.05).ConclusionsSarcopenia at T5 is associated with worse survival in males, but not females. When using upper thoracic vertebral levels to assess for sarcopenia, it is necessary to account for gender.

Project description:BackgroundChronic low-grade inflammation has been suggested as one of the key elements in the development of sarcopenia, but in contrast to disease-related loss of muscle mass, the role of chronic low-grade inflammation in age-related (primary) sarcopenia is still not clear. The aim of this study was to investigate low-grade inflammation in relation to age and the potential association between inflammatory biomarkers and body composition, muscle strength and physical performance in a healthy Danish cohort.MethodsThere were 1160 generally healthy men and women (range: 22-93 years) included. Appendicular lean mass (ALM) and visceral fat normalized to height (kg/m2 ) was assessed by dual-energy X-ray absorptiometry (iDXA, GE Lunar). Muscle strength and physical performance were evaluated by handgrip strength (HGS), 30 s sit-to-stand performance, and maximal gait speed (GS). Systemic levels of TNF-α, IL-6, IL-1β, IL-4, IL-13, and IFN-γ were measured using multiplex bead-based immunoassays (Bio-Rad). hsCRP was assessed using latex particle-enhanced immunoturbidimetric assays (Roche Diagnostics).ResultsWith age, ALM/h2 , HGS, sit-to-stand performance and GS decreased, whereas visceral fat/h2 increased in both men and women (P < 0.05). Systemic levels of hsCRP, TNF-α, IL-4, and IFN-γ increased with age in men and women (P < 0.05), while IL-1β increased in women only (P < 0.01). Higher levels of hsCRP were associated with lower ALM/h2 in elderly (≥65 years) men and women (P < 0.001). Higher levels of hsCRP were associated with lower handgrip strength in elderly women (P < 0.05) whereas higher levels of hsCRP was not associated with lower HGS in elderly men (P = 0.056). Higher levels of hsCRP were associated with lower GS (P < 0.05), whereas IFN-γ was positively associated with GS in elderly women (P < 0.05), but not elderly men. Visceral fat index was positively associated with hsCRP in elderly men and women (P < 0.001). Compared with elderly with normal HGS, elderly men and women with low HGS displayed higher levels of TNF-α and hsCRP (P < 0.05).ConclusionsWith age, systemic levels of hsCRP, TNF-α, IL-4, and IFN-γ increased, with hsCRP and TNF-α being especially elevated in more physically frail elderly supporting the association between low-grade systemic inflammation and poor physical function. In contrast, only high levels of hsCRP were weakly associated with low muscle mass and positively associated with visceral fat and low physical function, suggesting that chronic low-grade inflammation is not the main driver of age-related loss of muscle mass as previously suggested.

Project description:BACKGROUND:Body mass index (BMI), sarcopenia, and obesity-related comorbidities have been associated with head and neck squamous cell carcinoma (HNSCC) progression. METHODS:We conducted a retrospective analysis of 441 normal-weight, overweight, and obese HNSCC patients treated at Montefiore Medical Center (New York). Patients were grouped by BMI prior to treatment and assessed for differences in survival adjusting for comorbid conditions (cardiovascular disease and diabetes). Evidence of sarcopenia was also assessed using pretreatment abdominal CT scans in a subset of 113 patients. RESULTS:Prior to treatment, 55% of HNSCC patients were overweight or obese. Overweight/obese patients had significantly better overall survival (hazard ratio [HR]?= 0.4, 95% CI: 0.3-0.6) compared to normal-weight patients, independent of comorbid conditions. Patients with sarcopenia had significantly poorer survival (HR?= 2.1, 95% CI: 1.1-3.9) compared to non-sarcopenic patients, with the strongest association seen among overweight/obese patients. CONCLUSION:Our data support the importance of sarcopenia assessment, in addition to BMI, among patients with HNSCC.

Project description:Arteriovenous fistula (AVF) maturation failure is the primary cause of dialysis vascular access dysfunction. To evaluate whether preoperative vascular functional properties predict postoperative AVF measurements, patients enrolled in the Hemodialysis Fistula Maturation Study underwent up to five preoperative vascular function tests (VFTs): flow-mediated dilation (FMD), nitroglycerin-mediated dilation (NMD), carotid-femoral pulse wave velocity, carotid-radial pulse wave velocity, and venous occlusion plethysmography. We used mixed effects multiple regression analyses to relate each preoperative VFT to ultrasound measurements of AVF blood flow rate and venous diameter at 1 day, 2 weeks, and 6 weeks after AVF placement. After controlling for AVF location, preoperative ultrasound measurements, and demographic factors (age, sex, race, and dialysis status), greater NMD associated with greater 6-week AVF blood flow rate and AVF diameter (per absolute 10% difference in NMD: change in blood flow rate =14.0%; 95% confidence interval [95% CI], 3.7% to 25.3%; P<0.01; change in diameter =0.45 mm; 95% CI, 0.25 to 0.65 mm; P<0.001). Greater FMD also associated with greater increases in 6-week AVF blood flow rate and AVF diameter (per absolute 10% difference in FMD: change in blood flow rate =11.6%; 95% CI, 0.6% to 23.9%; P=0.04; change in diameter =0.31 mm; 95% CI, 0.05 to 0.57 mm; P=0.02). None of the remaining VFT parameters exhibited consistent statistically significant relationships with both postoperative AVF blood flow rate and diameter. In conclusion, preoperative NMD and FMD positively associated with changes in 6-week AVF blood flow rate and diameter, suggesting that native functional arterial properties affect AVF development.

Project description:ObjectivesWe sought to quantify the relationship between body mass index (BMI) and physical function among endometrial cancer survivors. Understanding this relationship would help healthcare providers target efforts to refer obese endometrial cancer survivors to weight loss and exercise interventions.MethodsWe conducted a survey of 213 endometrial cancer survivors who received cancer care at an academic l health system between 2006 and 2010. Physical function subscale was quantified using physical functional component score from the SF-12 questionnaire. We compared physical function of endometrial cancer survivors to population-based age-standardized normative values.ResultsAmong the 213 patients, 16% were normal weight (BMI ≤25 kg/m2), and 52% were obese (≥30 kg/m2). Higher BMI categories were associated with lower physical function (Ptrend = 0.003), as a continuous variable each 5kg/m2 higher BMI, physical function score was lower by 0.15 points (β = -0.15; P = 0.045). Compared to population-based age-standardized normative values, patients <75yrs reported lower physical function, whereas patients ≥75yrs reported better physical function. BMI was the only covariate associated with differences in physical function between survivors and age-standardized normative values (P = 0.039).ConclusionsAmong endometrial cancer survivors, higher BMI is associated with lower physical function. Younger endometrial cancer survivors report lower physical function compared to age-standardized normative values. Healthcare providers should be aware that younger, obese endometrial cancer survivors may particularly benefit from interventions such as exercise and weight loss to increase or preserve physical function.

Project description:ImportanceSarcopenia, or the loss of muscle mass, is associated with poor treatment outcomes in a variety of surgical fields. However, the association between sarcopenia and long-term survival in a broad cohort of patients with head and neck cancer (HNC) is unknown.ObjectiveTo determine whether sarcopenia is associated with long-term survival in patients undergoing major head and neck surgery for HNC.Design, setting, and participantsA retrospective medical records review was conducted at a tertiary care academic hospital. Two hundred sixty patients undergoing major head and neck ablative procedures with cross-sectional abdominal imaging performed within 45 days prior to surgery were included in the analysis. The study was conducted from January 1, 2005, to December 31, 2016. Data analysis was performed from June 1, 2018, to February 28, 2019.InterventionsMeasurement of cross-sectional muscle area at the L3 vertebra level.Main outcomes and measuresTwo- and 5-year overall survival were the primary outcomes.ResultsOf the 260 patients included in the study, 193 were men (74.2%); mean (SD) age was 61.1 (11) years. Sarcopenia was present in 144 patients (55.4%). Two-year overall survival was 71.9% of the patients (n = 82) in the sarcopenia group compared with 88.5% of the patients (n = 85) in the nonsarcopenia group (odds ratio [OR], 0.33; 95% CI, 0.16-0.70). At 5 years, overall survival was 36.5% in patients (n = 23) with sarcopenia and 60.5% in patients (n = 26) without sarcopenia (OR, 0.38; 95% CI, 0.17-0.84). On multivariate analysis, sarcopenia was a significant negative predictor of both 2-year (OR, 0.33; 95% CI, 0.14-0.77) and 5-year (OR, 0.38; 95% CI, 0.17-0.84) overall survival.Conclusions and relevanceSarcopenia appears to be a significant negative predictor of long-term overall survival in patients with HNC undergoing major head and neck surgery. Sarcopenia may be accurately assessed on cross-sectional imaging and may be useful clinically as a prognostic variable and as an area for intervention to improve treatment outcomes.
