Bioimpedance-derived body composition parameters predict mortality and dose-limiting toxicity: the multicenter ONCO-BIVA study.

Background: In patients with cancer, lean body mass loss is frequent and associated with worse outcomes, including reduced treatment tolerance and survival. Bioelectrical impedance analysis (BIA) is a popular method for body composition assessment. We evaluated the value of BIA-derived body composition parameters in predicting mortality and, for the first time, dose-limiting toxicity (DLT).

Gut Microbiota, Metabolome, and Body Composition Signatures of Response to Therapy in Patients with Advanced Melanoma.

Despite the recent breakthroughs in targeted and immunotherapy for melanoma, the overall survival rate remains low. In recent years, considerable attention has been paid to the gut microbiota and other modifiable patient factors (e.g.

Preterm birth and metabolic implications on later life: A narrative review focused on body composition.

Preterm newborn infants are characterized by low body weight and lower fat mass at birth compared with full-term newborn neonates. Conversely, at term corrected age, body fat mass is more represented in preterm newborn infants, causing a predisposition to developing metabolic syndrome and cardiovascular diseases in later life with a different risk profile in men as compared with women. Postnatal growth is a complex change in anthropometric parameters and body composition.

Risk of misclassification during diagnosis of malnutrition in retroperitoneal sarcoma patients.

Background: Retroperitoneal sarcoma (RPS) is a rare tumour that can reach exceptionally large size at diagnosis and affects body weight with its volume. We investigated the risk of nutritional status misclassification based on the Global Leadership Initiative on Malnutrition (GLIM) criteria in RPS patients.

Methods: We retrospectively analyzed the baseline data of patients with primary RPS including anthropometry, Malnutrition Universal Screening Tool (MUST) score and skeletal muscle index (SMI) calculated on preoperative CT scan.

Nutritional status and body composition assessment in patients with a new diagnosis of advanced solid tumour: Exploratory comparison of computed tomography and bioelectrical impedance analysis.

Objective: Low skeletal muscle is a common characteristic of cancer-related malnutrition and a predictor of poorer prognosis in oncological patients. In this study we evaluated nutritional status and altered body composition using computed tomography (CT) and bioelectrical impedance analysis (BIA) in newly diagnosed patients. Our purpose was to compare the results of two available techniques to assess body composition suggested by the guidelines and some diagnostic criteria to identify malnutrition.

Exploiting FAsting-mimicking Diet and MEtformin to Improve the Efficacy of Platinum-pemetrexed Chemotherapy in Advanced LKB1-inactivated Lung Adenocarcinoma: The FAME Trial.

Advanced lung adenocarcinoma with inactive liver kinase B1 (LKB1) tumor suppressor protein is associated with poor response to immune checkpoint inhibitors and molecularly targeted agents, and with dismal patient prognosis. LKB1 is a central orchestrator of cancer cell metabolism, and halts tumor growth/proliferation during metabolic stress. Recent preclinical evidence suggests that LKB1-inactive lung adenocarcinoma is highly sensitive to metformin, a safe and low-cost antidiabetic compound that inhibits mitochondrial oxidative phosphorylation.

Changes in food habits in cancer patients in Italy: a survey. AIOM - SINPE - FAVO.

Objectives: The aim of this study was to investigate the prevalence of cancer patients changing their diet in relation to cancer site, sex, age and geographic distribution. Furthermore, we aimed to explore the rationale behind dietary changes and to identify sources of information in order to plan specific educational training.
