Effect of body tissue composition on the outcome of patients with metastatic non-small cell lung cancer treated with PD-1/PD-L1 inhibitors.

Obesity and sarcopenia have been reported to affect outcomes in patients with non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs). We analyzed prospective data from 52 patients with non-oncogene driven metastatic NSCLC treated with ICIs. Body tissue composition was calculated by measuring the fat and muscle densities at the level of 3rd lumbar vertebra in each patient computed tomography scan before ICI initiation using sliceOmatic tomovision.

Objective Measurements of Physical Function to Predict Survival in Patients with Metastatic Cancer.

Background/objectives: Physician-reported performance status (PS) constitutes the established method for stratifying oncologic patients in therapeutic decision-making. Objective measurements of physical function may further refine prognostication.

Subjects/methods: In this prospective observational study, 103 patients with metastatic cancer who were referred for systemic therapy initiation were evaluated.

Cancer Cachexia and Antitumor Immunity: Common Mediators and Potential Targets for New Therapies.

Cancer cachexia syndrome (CCS) is a multifactorial metabolic syndrome affecting a significant proportion of patients. CCS is characterized by progressive weight loss, alterations of body composition and a systemic inflammatory status, which exerts a major impact on the host's innate and adaptive immunity. Over the last few years, the development of immune checkpoint inhibitors (ICIs) transformed the treatment landscape for a wide spectrum of malignancies, creating an unprecedented opportunity for long term remissions in a significant subset of patients.

Phase III study of the European Organisation for Research and Treatment of Cancer Quality of Life cancer survivorship core questionnaire.

Purpose: The purpose of this study is to develop a European Organisation for Research and Treatment of Cancer Quality of Life Group (EORTC QLG) questionnaire that captures the full range of physical, mental, and social health-related quality of life (HRQOL) issues relevant to disease-free cancer survivors. In this phase III study, we pretested the provisional core questionnaire (QLQ-SURV111) and aimed to identify essential and optional scales.

Methods: We pretested the QLQ-SURV111 in 492 cancer survivors from 17 countries with one of 11 cancer diagnoses.

Cancer cachexia syndrome and clinical outcome in patients with metastatic non-small cell lung cancer treated with PD-1/PD-L1 inhibitors: results from a prospective, observational study.

Background: Cancer cachexia syndrome (CCS) is an adverse prognostic factor in cancer patients undergoing chemotherapy or surgical procedures. We performed a prospective study to investigate the effect of CCS on treatment outcomes in patients with non-oncogene driven metastatic non-small cell lung cancer (NSCLC) undergoing therapy with programmed cell death protein 1 (PD-1)/programmed death ligand 1 (PD-L1) inhibitors.

Methods: Patients were categorized as having cancer cachexia if they had weight loss >5% in the last 6 months prior to immunotherapy (I-O) initiation or any degree of weight loss >2% and body mass index (BMI) <20 kg/m or skeletal muscle index at the level of third lumbar vertebra (LSMI) <55 cm/m for males and <39 cm/m for females.

Diagnostic criteria for cancer cachexia: reduced food intake and inflammation predict weight loss and survival in an international, multi-cohort analysis.

Background: Cancer-associated weight loss (WL) associates with increased mortality. International consensus suggests that WL is driven by a variable combination of reduced food intake and/or altered metabolism, the latter often represented by the inflammatory biomarker C-reactive protein (CRP). We aggregated data from Canadian and European research studies to evaluate the associations of reduced food intake and CRP with cancer-associated WL (primary endpoint) and overall survival (OS, secondary endpoint).

Cancer-associated anorexia: Validity and performance overtime of different appetite tools among patients at their first cancer diagnosis.

Background & Aims: Anorexia is a frequent symptom in cancer and we aimed to assess its prevalence among patients at their first cancer diagnosis by different appetite tools and the relationship between each tool with self-reports of food intake. We also tested whether cancer anorexia influences outcomes independently of reduced food intake or body weight loss (BWL) overtime and whether BWL was associated with complications during anticancer-therapy.

Methods: Functional Assessment of Anorexia/Cachexia Therapy (FAACT) score, self-assessment of appetite, Anorexia Questionnaire (AQ) and Visual Analog Scale (VAS) were administered.

Cancer-Associated Malnutrition and CT-Defined Sarcopenia and Myosteatosis Are Endemic in Overweight and Obese Patients.

Background: Overweight/obese patients' large fat mass can mask the loss of skeletal muscle, which is associated with mortality in the oncology setting. We investigated the prevalence of computed tomography (CT)-defined sarcopenia and myosteatosis across different levels of nutrition risk assessed by the Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF). We also evaluated whether the PG-SGA SF, sarcopenia, and myosteatosis were prognostic of overall survival.

New genetic signatures associated with cancer cachexia as defined by low skeletal muscle index and weight loss.

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 to genotype.

Detailed Dietary Assessment in Patients with Inoperable Tumors: Potential Deficits for Nutrition Care Plans.

Advanced cancer often results in reduced dietary intake; however, data on actual intake at the time of diagnosis are limited. In the present study, a detailed dietary intake assessment was performed in patients with metastatic lung and upper gastrointestinal cancer, before initiation of systemic therapy. Basic demographics and performance status (PS) were recorded.

Prognosis in advanced lung cancer--A prospective study examining key clinicopathological factors.

Objectives: In patients with advanced incurable lung cancer deciding as to the most appropriate treatment (e.g., chemotherapy or supportive care only) is challenging.

Diagnostic criteria for the classification of cancer-associated weight loss.

Purpose: Existing definitions of clinically important weight loss (WL) in patients with cancer are unclear and heterogeneous and do not consider current trends toward obesity.

Methods: Canadian and European patients with cancer (n = 8,160) formed a population-based data set. Body mass index (BMI) and percent WL (%WL) were recorded, and patients were observed prospectively until death.

Nutritional assessment in overweight and obese patients with metastatic cancer: does it make sense?

Background: Obesity is causally related with tumor development, and thus, many cancer patients are overweight or obese at diagnosis. Whether these patients need regular nutritional assessment is not known. In the present study, we evaluated the utility of Mini Nutritional Assessment (MNA), a nutritional screening/assessment questionnaire, in overweight or obese patients with metastatic tumors.

Montreal prognostic score: estimating survival of patients with non-small cell lung cancer using clinical biomarkers.

Background: For evidence-based medical practice, well-defined risk scoring systems are essential to identify patients with a poor prognosis. The objective of this study was to develop a prognostic score, the Montreal prognostic score (MPS), to improve prognostication of patients with incurable non-small cell lung cancer (NSCLC) in everyday practice.

Methods: A training cohort (TC) and a confirmatory cohort (CC) of newly diagnosed patients with NSCLC planning to receive chemotherapy were used to develop the MPS.

Predictive and prognostic value of LPS-stimulated cytokine secretion in metastatic non-small cell lung cancer.

Objective: Cancer patients usually develop malnutrition which may alter their innate immune system integrity. The aim of this study was to investigate the clinical relevance of chemokine response after lipopolysaccharide (LPS)-stimulation in metastatic non-small cell lung cancer (NSCLC).

Methods: Blood samples from metastatic NSCLC patients were incubated with LPS before the onset of systemic therapy.

The Glasgow Prognostic Score (GPS) predicts toxicity and efficacy in platinum-based treated patients with metastatic lung cancer.

Purpose: Lung cancer is the most common cause of cancer death. A cumulative prognostic score based on C-reactive protein and albumin, termed the Glasgow Prognostic Score (GPS), indicates the presence of systemic inflammatory response. GPS has been proposed as a powerful prognostic tool for patients with various types of malignant tumors, including lung cancer.

Lack of prognostic significance of p16 and p27 after radical prostatectomy in hormone-naïve prostate cancer.

Background: Loss of normal cell cycle control is an early event in the evolution of cancer. The expression of cyclin-dependent kinase (CDK) inhibitors p16 and p27 has been previously associated with progression of prostate cancer (PC). 70 patients diagnosed with early stage PCwere treated with radical prostatectomy (RP) at our institution and their tumor specimens were immunohistochemically evaluated for expression of p16 and p27.

Baseline plasma levels of interleukin-8 in stage IV non-small-cell lung cancer patients: relationship with nutritional status and prognosis.

Interleukin (IL)-8 promotes cellular proliferation and angiogenesis in patients with non-small-cell lung cancer (NSCLC) and may be related to cachexia. Our aim was to investigate the relationship of IL-8 levels with nutritional status, and clinical outcome of patients with NSCLC. Patients with metastatic NSCLC referred for first-line therapy were eligible.

Baseline insulin-like growth factor-I plasma levels, systemic inflammation, weight loss and clinical outcome in metastatic non-small cell lung cancer patients.

Background: Cancer patients frequently suffer from weight loss and systemic inflammation in the context of advanced disease, which is related to adverse outcome. Insulin-like growth factor (IGF)-I is an anabolic molecule implicated in the maintenance of muscle mass and cancer growth. We investigated potential correlations of IGF-I with an inflammatory and weight loss status and with clinical outcome.
