Nutrition and Cancer

This hospital-based, cross-sectional study aimed to explore the association between diet and fluctuating intestinal bacteria in early-stage colorectal cancer (CRC) ( Atopobium parvulum , Actinomyces odontolyticus , Solobacterium moorei , and Bifidobacterium longum ). Healthy participants ( n  = 212) who underwent total colonoscopy at National Cancer Center Hospital (Tokyo, Japan) were divided into two groups according to the relative abundance of bacteria in their feces: those in the top 25% of relative bacterial abundance as cases and the bottom 25% as controls...

Post-gastrectomy syndrome (PGS) and body weight loss (BWL) decrease quality of life (QOL) and survival of the patient undergoing gastrectomy. We have introduced perioperative and post-discharge continuous nutritional counseling (CNC) to prevent BWL and improve QOL after gastrectomy. In the present study, we evaluated the effect of CNC on QOL using the Post-gastrectomy Syndrome Assessment Scale-45 (PGSAS-45). Eighty-three patients with gastric cancer (GC) who underwent curative gastrectomy between March 2018 and July 2019 were retrospectively analyzed...

This study aimed to investigate the additional effects of perioperative immunonutrition (IMN) compared with preoperative immunonutrition (IMN) on anthropometric, nutritional, and biochemical parameters, hospital stay and postoperative complications in patients with colorectal cancer. Oral supplementation enriched with arginine, omega-3 fatty acids, and dietary nucleotides was given to 25 patients before and after the operation (Group 2); 25 patients received the same formula before surgery and standard isocaloric nutrition following the operation (Group 1)...

Methionine is an essential amino acid critical for cell growth and survival. Preclinical evidence suggests a methionine restricted diet (MRD) sensitizes cancer to radiation therapy (RT), without significant adverse effects. However, this has never been evaluated in humans. The purpose of this pilot study was to evaluate the safety and feasibility of concurrent MRD with standard-of-care definitive RT in adults with any non-skin cancer malignancy. The MRD extended from 2 wk before RT initiation, through 2 wk beyond RT completion...

The incidence and mortality rates of esophageal squamous cell carcinoma (ESCC) have been significantly increasing in China. Indole-3-carbinol (I3C), a naturally occurring component in cruciferous vegetables, is an effective cancer therapy. Yet, its effect and action mechanism in ESCC are still not fully understood. This study explored the role of I3C in ESCC in vitro and in vivo by focusing on the Wnt/β-catenin signaling pathway. MTT and flow cytometry were used to assess cell viability and apoptosis in EC18 and TE1 cells, while wound healing and transwell assays were used to investigate cell migration and invasion in vitro...

Astaxanthin (AST) is a natural marine carotenoid with a variety of biological activities. This study aimed to demonstrate the possible mechanisms by which AST improves skeletal muscle atrophy in cancer cachexia. In this study, the effects of different doses of AST (30 mg/kg b.w., 60 mg/kg b.w. and 120 mg/kg b.w.) on skeletal muscle functions were explored in mice with cancer cachexia. The results showed that AST (30, 60 and 120 mg/kg b.w.) could effectively protect cachexia mice from body weight and skeletal muscle loss...

A cross-sectional analysis explored nutritional intakes and gastrointestinal (GI) symptoms among esophagogastric cancer survivors up to 12, 13-36, and 37+ months post-surgery. Participants were identified from the Upper GI Cancer Registry at St James' Hospital, Ireland. The Short Nutritional Assessment Questionnaire, European Prospective Investigation of Cancer Food Frequency Questionnaire, World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Score, and Gastrointestinal Symptoms Rating Scale assessed malnutrition risk, nutritional intake, adherence to (secondary) cancer prevention recommendations, and GI symptoms, respectively...

Studies on the prognostic value of the blood 25-hydroxyvitamin D level have yielded controversial results in prostate cancer (PCa) patients. This updated meta-analysis aimed to evaluate the association between pretreatment 25-hydroxyvitamin D level with survival outcomes among patients with clinically localized PCa. PubMed, Web of Science, and Embase databases were searched to identify studies evaluating the association of pretreatment 25-hydroxyvitamin D level with PCSM and all-cause mortality among clinically localized PCa patients...

BACKGROUND: Observational studies suggests that diets and medications affect bladder cancer (BC) development, which are subject to confounding and difficult to make causal inference. Here we aimed to investigate whether those observational associations are causal and determining the potential directions and pathways. METHODS: We used 2-sample Mendelian randomization (MR) analysis to assess associations of dietary intakes, medication uses and molecules with BC risk...

Approximately 5,700 people are diagnosed with myeloma each year in the UK. The standard of care is to receive an autologous stem cell transplant after completion of induction therapy. There are no specific dietary recommendations for people with myeloma, however they are at risk of malnutrition due to symptoms and side effects of treatments. This report describes the journey of a 73-year-old male diagnosed with immunoglobulin A (IgA) lambda myeloma in April 2021. The patient lost 23% of his body weight during 6 months of systemic anti-cancer treatment (SACT), resulting in postponing his transplant twice due to reduced fitness...

Patients who undergo autologous hematopoietic stem cell transplantation (autoHSCT) often experience reduced oral intake and wasting. We examined their daily nutritional intake, assessed alterations in body composition and muscle strength, and explored associations between decreased nutritional intake and treatment outcomes. This retrospective study included 64 patients. Their food record charts and parenteral nutrition (PN) prescriptions from medical records were used to assess nutritional intake. Body composition and handgrip strength data were obtained from dietitian records...

AIM: Malnutrition is prevalent in hepatocellular carcinoma (HCC) patients, linked to poor outcomes, necessitating early intervention. This study aimed to investigate malnutrition in HCC patients, assess Nutrition Risk Screening 2002 (NRS-2002) and Patient-Generated Subjective Global Assessment (PG-SGA) vs. Global Leadership Initiative on Malnutrition (GLIM) criteria, and identify independent risk factors. METHOD: A cross-sectional retrospective study was conducted on 207 patients with HCC...

Malnutrition significantly impacts the post-operative process of gynecological cancer patients. A prominent variable for determining perioperative morbidity is the Prognostic Nutritional Index (PNI). To investigate PNI's predictive value on the risk of post-operative infections, we conducted a prospective cohort study involving women who underwent surgery for gynecological malignancies. Out of the 208 patients enrolled, 28 (13.5%) were malnourished and post-operative infections occurred in 43 patients. Notably, there was a significant difference in PNI between patients who developed infections and those who did not ( p  = 0...

Esophageal carcinoma (EC) and nutritional status are strongly linked due to swallowing disruptions and treatment-related toxicities. Therefore, malnutrition and weight loss (WL) occur in 85% and 79% of EC patients, respectively. WL is frequently associated with worse EC patient outcomes, however, WL during radiation therapy (RT) and EC patient outcomes have not been well established. The purpose of this study is to retrospectively review the association of WL during RT treatment of EC with clinical outcomes...

Low dietary fiber consumption is associated with an increased risk of colorectal cancer, a leading cause of cancer-related mortality in the United States. The average daily fiber intake has declined over recent decades. Notably, Black Americans exhibit lower fiber consumption than other racial/ethnic groups, possibly influencing their elevated colorectal cancer rates. We hypothesize that there has been a significant increase in dietary fiber consumption in the United States from 1999 to 2017. The study encompassed 59,204 adult NHANES participants and observed variations in caloric intake over survey years...

Idebenone, a mitochondrial regulator, has exhibited anti-cancer activity in neurogenic and prostate tumor cells; however, its efficacy and specific targets in the treatment of triple-negative breast cancer (TNBC) remain unclear. This study aims to evaluate the potential of Idebenone as a therapeutic agent for TNBC. TNBC cell lines and Xenograft mouse models were used to assess the effect of Idebenone on TNBC both in vitro and in vivo . To investigate the underlying mechanism of Idebenone's effect on TNBC, cell viability assay, transwell invasion assay, cell cycle analysis, apoptosis assay, mitochondrial membrane potential assay, immunofluorescence staining, and transcriptome sequencing were utilized...

This study aimed to examine the effects of an animated Patient Decision Aid (PtDA) about dietary choices on decisional conflict and decision regret. A prospective, observational, two-group comparative effectiveness study was conducted with patients ( n  = 90) from a southern Taiwan oncology inpatient unit. Data included the Malnutrition Universal Screening Tool (MUST), laboratory results, 16-item Decisional Conflict Scale (sf-DCS), and 5-item Decision Regret Scale (DRSc). Data were collected at admission (T0), after the first-cycle of chemotherapy but before discharge (T1), and after the six-cycle chemotherapy protocol (T2) (around 3 months)...

Abdominal adiposity is associated with tumor development and poor clinical outcomes in breast cancer (BC) and can be identified by the measurement of waist circumference (WC) and visceral adipose tissue (VAT). This study aimed to evaluate the association between waist circumference (WC) and imaging measurement of central adiposity according to age group in women with BC. Abdominal adiposity was assessed by WC and VAT, obtained by dual-energy X-ray absorptiometry (DXA). Body mass index (BMI) was assessed. The presence of inflammation was investigated by measuring C-Reactive Protein (CRP) levels...

Blood cell biomarkers, such as the neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR), have been recently used as prognostic markers in tumors. In this study, we investigated the association between NLR and PLR with sociodemographic, clinical, anthropometric, and quality of life factors of hospitalized women with non-metastatic breast cancer. A cross-sectional observational study was conducted at a reference center for oncological treatment in Southeast Brazil. Female participants aged over 18 years, with a histopathological diagnosis of stage I, II or III breast cancer, in any phase of antineoplastic treatment, were included...
