FcRn function alone cannot account for elevated IgG clearance in the Lewis lung carcinoma model of cancer cachexia.
PURPOSE
The neonatal Fc receptor (FcRn) protects IgG-based monoclonal antibodies (mAbs) from catabolism by direct binding within endosomes and facilitates their recycling to extracellular spaces. Elevated clearance of immune checkpoint inhibitors (ICIs) and other IgG-based mAbs is often observed in patients...
Beyond the Lungs: The Role of Extrapulmonary Manifestations in the Quality of Life of Indians with Chronic Airway Diseases.
PURPOSE
Chronic airway diseases (CAD) including Chronic obstructive pulmonary diseases (COPD), persistent asthma (≥2weekly episodes) and bronchiectasis, exhibit overlapping extrapulmonary manifestations potentially affecting health-related quality-of-life (HRQOL). The study objective was to quantify HRQOL of CAD patients and identify impact of associated...
Cancer IDO1-Mediated Tryptophan-Kynurenine Metabolic Reprogramming to Drive Skeletal Muscle Atrophy and Cachexia Acceleration.
BACKGROUND
Cancer cachexia is a debilitating syndrome characterized by severe skeletal muscle wasting, which significantly impairs patient quality of life and survival. Indoleamine 2,3-dioxygenase 1 (IDO1), a key enzyme in tryptophan (Trp) metabolism, is often upregulated in cancers, but its specific...
Circulating Inflammatory and Mitochondrial Biomarkers Associated with Cachexia in Advanced Non-Small Cell Lung Cancer.
Background: Cancer-associated cachexia is a multifactorial metabolic syndrome characterized by progressive skeletal muscle and/or adipose tissue loss and affects approximately 40% of patients with non-small cell lung cancer (NSCLC). However, reliable circulating biomarkers for early detection and risk stratification remain...
High Fat Diet and Obesity Each Increase Tumor Cell Proliferation and Muscle Wasting in Experimental Cancer Cachexia.
High fat diet (HFD) and associated obesity are suggested to predispose to cancer development, complicate cancer treatment, and accelerate mortality. Paradoxically, obese patients with lung cancer are reported to live longer, suggesting that high body mass is protective. Given that...
Cancer Cachexia Prevalence Is Underestimated in Medical Records of Patients in a Regional Tertiary Hospital.
BACKGROUND
Widespread lack of awareness and limited real-world prevalence evidence have impeded cachexia care and research. We hypothesized that healthcare professionals may identify the term cachexia, leading to International Classification of Diseases (ICD) coding for this term, with or without records...
Cancer cachexia in STK11/LKB1-mutated non-small cell lung cancer is dependent on tumor-secreted GDF15.
Cachexia is a wasting syndrome involving adipose, muscle, and body weight loss in cancer patients. Tumor loss-of-function mutations in STK11/LKB1, a regulator of AMP-activated protein kinase, induce cancer cachexia (CC) in preclinical models and are linked to weight loss in...
Concurrent PIK3CA mutant promotes cachexia through inflammatory signaling in EGFR mutant lung cancer.
PIK3CA mutation is frequently concurrent with known oncogenic drivers such as EGFR mutation in lung cancer, raising an interesting question about its real function. Cachexia is a systemic disease arising from tumor-organ crosstalk, significantly contributing to cancer-related mortality. Through integrative...
From Symptom to Outcome: Defining Clinically Meaningful Patient-Reported Appetite Loss in Non-Small-Cell Lung Cancer.
BACKGROUND
Appetite loss is a common and distressing symptom in non-small-cell lung cancer (NSCLC), driven by both treatment side effects and disease progression. It often leads to unintended weight loss and cancer cachexia, significantly impairing patients' quality of life and survival....
Tailored Exercise Prescription for People with COPD and Clinically Relevant Comorbidities: A Consensus Statement of the EXPERT Working Group and Experts in Pulmonary Rehabilitation.
Chronic obstructive pulmonary disease (COPD) is a heterogeneous chronic lung condition often accompanied by comorbidities and systemic manifestations that affect the person's clinical condition and prognosis and often require specific treatment. Therefore, the management of COPD extends beyond treatment for...
Evaluation of Weight Gain and Overall Survival of Men Versus Women With Advanced Non-Small Cell Lung Cancer.
BACKGROUND
Weight stabilization or gain during cancer treatment is associated with increased survival. Analyses of weight gain by sex during cancer treatment and the effects of weight on survival have not been fully studied. This post hoc analysis retrospectively examined the...
Association of Pre- and Postdiagnosis Physical Activity, Promotion and Maintenance With Lung Cancer Survival: A Nationwide Cohort Study.
BACKGROUND
Physical activity (PA) is important for improving life expectancy and is suggested as a prognostic factor for various diseases. However, the association between PA and mortality outcomes in survivors of lung cancer remains unclear. Therefore, this study aimed to determine...
Beyond Body Mass Index: The Impact of Height and Height-Normalised Weight on Overall Survival of Lung Cancer Undergoing Surgery.
Unlike most malignancies, increased adiposity, as expressed by a higher body mass index (BMI), is associated with improved prognosis after lung cancer surgery at the population level. Height, one of the determinants of BMI, is associated with better survival, independent...
Exploration of Fully-Automated Body Composition Analysis Using Routine CT-Staging of Lung Cancer Patients for Survival Prognosis.
AI-driven automated body composition analysis (BCA) may provide quantitative prognostic biomarkers derived from routine staging CTs. This two-centre study evaluates the prognostic value of these volumetric markers for overall survival in lung cancer patients. Lung cancer cohorts from Hospital A...
Sarcopenia, Elevated Body Mass Index, and Platinum-Associated Adverse Events in Patients With Lung Cancer.
Patients with sarcopenia and elevated body mass index (BMI) are at high risk of platinum-associated adverse events (AEs). This study examines the association between sarcopenia, BMI, and AEs in patients with non-small cell lung cancer (NSCLC). This retrospective cohort study...
