A dietary switch promotes sensory neuron-dependent cancer-associated cachexia.
Sickness behaviors are common in cancer-associated cachexia and affect up to half of lung cancer patients. We demonstrate that among the most common cancer mutations, loss of liver kinase B1 (Lkb1) promotes the development of cachexia in preclinical models of...
PEBP4 alleviates muscle wasting in lung cancer cachexia via KEAP1-NRF2-mediated redox homeostasis.
Cancer-associated cachexia (CAC) is a multifactorial metabolic syndrome characterized by progressive skeletal muscle wasting. However, the molecular link between tumor metabolic stress and muscle degradation remains elusive. Here, we identify phosphatidylethanolamine-binding protein 4 (PEBP4) as a key regulator of muscle...
Prognostic impact of weight loss during first-line chemotherapy in extensive-disease small cell lung cancer.
PURPOSE
The adverse prognostic impact of cancer cachexia is well recognized. We aimed to evaluate the prognostic impact of weight loss during first-line platinum-based chemo(immuno)therapy in patients with extensive-disease small-cell lung cancer (ED-SCLC).
METHODS
We retrospectively reviewed 187 of 346 ED-SCLC patients (54%)...
Novel Long-Acting Ghrelin Analogue PEP-064 Restores Energy Balance in C26 and Lewis Lung Carcinoma-Induced cachexia in Mice.
BACKGROUND
Cancer cachexia is a debilitating syndrome marked by involuntary weight loss resulting from reduced food intake and intricate metabolic reprogramming. Despite its high prevalence, cancer cachexia remains undertreated, with a lack of effective and approved pharmacotherapies. Ghrelin has emerged as...
Formation of Liver Metastases Is Accompanied by Accelerated Musculoskeletal Deficits in LLC Tumor Hosts.
Lung cancer is a leading cause of death worldwide and is often accompanied by declines in musculoskeletal health (i.e., cachexia). Despite affecting a majority of lung cancer patients, cachexia remains understudied and currently has no cure. We have previously demonstrated...
Correction to 'Sex Differences in Muscle-Respiratory Function Relationship in Lung Transplant Patients: A Longitudinal Study'.
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....
