Cancer cachexia is a multi-organ tissue wasting syndrome that contributes to morbidity and mortality in many cancer patients. Skeletal muscle loss represents an established key feature yet there no molecular understanding of the disease process. In fact, postulated regulators originate largely from pre-clinical models it unclear how these translate clinical environment.Rectus abdominis biopsies were obtained 65 upper gastrointestinal (UGI) patients during open surgery RNA profiling was...
Background Intramyocellular lipids are an important source of fuel for mitochondrial fat oxidation and play role in intramuscular lipid homeostasis. We hypothesised that due to the phenotype associated with cancer cachexia, there would exist association between increasing weight loss number/size intramyocellular droplets. Methods Nineteen patients 6 controls undergoing surgery were recruited. A rectus abdominis biopsy was performed processed transmission electron microscopy (TEM). The number...
Profound loss of adipose tissue is a hallmark cancer cachexia. Zinc-α2-glycoprotein (ZAG), recently identified adipokine, suggested as candidate in lipid catabolism. In the first study, eight weight-stable and 17 cachectic patients (weight ⩾5% previous 6 months) were recruited. mRNA protein expression assessed subcutaneous (SAT), morphology was examined serum ZAG concentrations quantified. second cohort, release by SAT determined 18 15 patients. The effect on lipolysis evaluated vitro....
The majority of cancer patients with advanced disease experience weight loss, including loss lean body mass. Severe is characteristic for cachexia, a condition that significantly impairs functional status and survival. underlying causes cachexia are incompletely understood, currently no therapeutic approach can completely reverse the condition. Autophagy coordinates lysosomal destruction cytosolic constituents systemically induced by starvation. We hypothesized starvation-mimicking signaling...
Abstract Purpose: The mechanisms underlying muscle wasting in patients with cancer remain poorly understood, and consequently there remains an unmet clinical need for new biomarkers treatment strategies. Experimental Design: Microarrays were used to examine the transcriptome single biopsies from healthy controls (n = 6) paired [pre-resection baseline (weight-loss 7%) 8 month post-resection follow-up (disease-free/weight-stable previous 2 months)] quadriceps of upper gastrointestinal (UGIC; n...
Background Cachexia affects the majority of patients with advanced cancer and is associated a reduction in treatment tolerance, response to therapy, duration survival. One impediment towards effective cachexia validated classification system. Methods 41 resectable upper gastrointestinal (GI) or pancreatic underwent characterisation for based on weight-loss (WL) and/or low muscularity (LM). Four diagnostic criteria were used >5%WL, >10%WL, LM, LM+>2%WL. All biopsy rectus muscle. Analysis...
Abstract Background In order to grow the potential therapeutic armamentarium in cachexia domain of supportive oncology, there is a pressing need develop suitable biomarkers and drug targets. This pilot study evaluated several candidate skeletal muscle biopsies from cohort upper gastrointestinal cancer (UGIC) patients. Methods One hundred seven patients (15 weight‐stable healthy controls (HC) 92 UGIC patients) were recruited. Mean (standard deviation) weight‐loss was 8.1 (9.3%). Cachexia...
Abstract Purpose: Skeletal muscle wasting and weight loss are characteristic features of cancer cachexia contribute to impaired function, increased morbidity, poor tolerance chemotherapy. This study used a novel technique measure habitual myofibrillar protein synthesis in patients with compared healthy controls. Experimental design: An oral heavy water (87.5 g deuterium oxide) tracer was administered as single dose. Serum samples were taken over the subsequent week followed by quadriceps...
Background Cachexia affects the majority with advanced cancer. Based on current demographic and clinical factors, it is not possible to predict who will develop cachexia or not. Such variation may, in part, be due genotype. It has recently been proposed extend diagnostic criteria for include a direct measure of low skeletal muscle index (LSMI) addition weight loss (WL). We aimed explore our panel candidate single nucleotide polymorphism (SNPs) association WL +/− computerized...
RATIONALE Conventionally, myofibrillar protein synthesis is measured over time periods of hours. In clinical studies, interventions occur weeks. Functional measures such may be more representative. We aimed to develop a novel method determine fractional synthetic rate (FSR) estimate habitual rates, while avoiding intravenous tracer infusions. METHODS Four healthy males were given 100 g water enriched 70 Atom % with 2 H O as single oral bolus. Vastus‐lateralis needle biopsies performed and...
Abstract Background A positive circumferential resection margin (CRM) has been associated with a poorer prognosis in oesophageal and oesophagogastric junctional (OGJ) cancer. The College of American Pathologists defines the CRM as if tumour cells are present at margin, whereas Royal also include within 1 mm this margin. relevance these differences is not clear no study investigated impact adjuvant therapy. aim was to identify optimal definition an involved patients undergoing for or OGJ...
Cachexia is a multifactorial wasting syndrome associated with high morbidity and mortality in patients cancer. Diagnosis can be difficult and, the clinical situation, usually relies upon reported weight loss. The ‘omics’ technologies allow us opportunity to study end points of many biological processes. Among these, blood-based metabolomics promising method investigate pathophysiology human cancer cachexia identify candidate biomarkers. In this study, we performed liquid chromatography mass...
