Nutritional screening and early treatment of malnutrition in cancer patients

Distress thermometer for preoperative screening of patients with oral squamous cell carcinoma

In this study, we evaluate the association between distress, various demographic and medical variables, and the prevalence of psychosocial distress in preoperative patients with oral squamous cell carcinoma. A total of 100 consecutive patients were recruited into the study and asked to complete the Distress Thermometer (DT) form with the Problem List questionnaire prior to surgical intervention; the average distress score was 5.7 ± 2.7. The distress score was neither correlated with age (r = -0.025; p = 0.804) nor with tumor size (r = 0.028; p = 0.785). General worries, anxiety, sadness, depression, pain, exhaustion, sleeping disorders, or problems with nutrition resulted in significantly higher distress scores compared to patients without these complaints. Individuals with a DT score of 5 or higher (p = 0.006) were advised to seek out psychological support. There is a strong correlation between a high DT score and emotional disorders, as well as physical problems.

The Role of Diet and Lifestyle in Women with Breast Cancer: An Update Review of Related Research in the Middle East

Breast cancer is the most common malignancy among Arab women in Eastern Mediterranean Region (EMR). The incidence of breast cancer has substantially increased in recent years among this women population, especially those younger than 50, and the incidence is expected to double by 2030. Considerable experimental evidence supports the potential role of dietary habits and lifestyle in cancer etiology and cancer prevention. In this review we examined the literature for evidence to link dietary choices and the rise in incidence and mortality of breast cancer among women in EMR. A literature search was conducted in PubMed and Ovid MEDLINE databases up to December 2017. The search terms used are breast cancer prevalence, breast cancer incidence worldwide, breast cancer and: nutrition, protein intake, vitamin D intake, fat intake, phytoestrogens, EMR, Arab, Middle East, Gulf countries, the UAE Arab women, breast cancer risk, diet, and chemoprevention. We found evidence to suggest that there is an alarming epidemic of obesity among women in most of the EMR countries, especially Gulf Cooperation Council (GCC) countries. The rise in the new breast cancer cases among women could be attributed to excess body weight. Their dietary pattern, which correlates with obesity, can be an important factor in the etiology of cancer. Although very few studies were found to support a direct causal relationship between obesity and breast cancer in the EMR, circumstantial evidence clearly points to the possible role of the epidemic, obesity, in this population and the startling rise in cases of breast cancer. Well-designed and systematic studies are urgently needed to confirm these associations and to elucidate potential mechanisms. More urgently, calls to action are needed in many sectors and at all levels of society, to establish intensive strategies for reducing obesity and promoting an overall healthy diet. Continued and expanded research on diet, lifestyle, and breast cancer risk is urgently needed to build the foundation for future progress in evidence-based public health efforts.

Nutritional Status in Patients with Gastrointestinal Cancer in Comparison To Other Cancers In Shiraz, Southern Iran: a Case-Control Study

BACKGROUND

Malnutrition leads to decreased survival rate, quality of life and the response to treatment and increases the risk of mortality in patients with cancer. Clinical evaluation is essential for ontime detection and treatment of malnutrition in these patients. On the other hand, patients with gastrointestinal (GI) cancers are expected to have a higher risk of malnutrition due to the poor digestion and malabsorption. Therefore, the purpose of this study was to compare the nutritional status in patients with GI tract cancers with non-GI cancers.

METHODS

Sixty-nine patients with GI cancers and 65 patients with other types of cancer participated in this case-control study. Anthropometric evaluation [weight, body mass index (BMI)], mid arm circumference, calf circumference) and biochemical indices [albumin, C-Reactive Protein (CRP)] were measured and the Subjective Global Assessment (SGA) questionnaire was completed to assess the nutritional status of the patients.

RESULTS

BMI, weight and serum albumin levels were significantly lower in patients with GI cancers. Other anthropometric measurements were lower in the case group and the serum CRP level was higher than the control group, although they were not statistically significant. The incidence of malnutrition was higher in case group compared to the control group, but it was not statistically significant.

CONCLUSION

Anthropometric, biochemical and SGA evaluation showed a poor nutritional status in patients with GI cancer compared to other forms of cancer. Therefore, early assessment of the nutritional status of patients with cancer can be effective in order to initiate a nutritional intervention.

Home parenteral nutrition for patients with intestinal failure due to advanced cancer

Patients who experience intestinal failure as a result of advanced malignancy can be supported with parenteral nutrition in their own home (HPN). This article describes how to identify which cancer patients would benefit from this therapy and how to ensure it is safely and correctly administered in the home setting.

Serum and urine metabolomics study reveals a distinct diagnostic model for cancer cachexia

BACKGROUND

Cachexia is a multifactorial metabolic syndrome with high morbidity and mortality in patients with advanced cancer. The diagnosis of cancer cachexia depends on objective measures of clinical symptoms and a history of weight loss, which lag behind disease progression and have limited utility for the early diagnosis of cancer cachexia. In this study, we performed a nuclear magnetic resonance-based metabolomics analysis to reveal the metabolic profile of cancer cachexia and establish a diagnostic model.

METHODS

Eighty-four cancer cachexia patients, 33 pre-cachectic patients, 105 weight-stable cancer patients, and 74 healthy controls were included in the training and validation sets. Comparative analysis was used to elucidate the distinct metabolites of cancer cachexia, while metabolic pathway analysis was employed to elucidate reprogramming pathways. Random forest, logistic regression, and receiver operating characteristic analyses were used to select and validate the biomarker metabolites and establish a diagnostic model.

RESULTS

Forty-six cancer cachexia patients, 22 pre-cachectic patients, 68 weight-stable cancer patients, and 48 healthy controls were included in the training set, and 38 cancer cachexia patients, 11 pre-cachectic patients, 37 weight-stable cancer patients, and 26 healthy controls were included in the validation set. All four groups were age-matched and sex-matched in the training set. Metabolomics analysis showed a clear separation of the four groups. Overall, 45 metabolites and 18 metabolic pathways were associated with cancer cachexia. Using random forest analysis, 15 of these metabolites were identified as highly discriminating between disease states. Logistic regression and receiver operating characteristic analyses were used to create a distinct diagnostic model with an area under the curve of 0.991 based on three metabolites. The diagnostic equation was Logit(P) = -400.53 - 481.88 × log(Carnosine) -239.02 × log(Leucine) + 383.92 × log(Phenyl acetate), and the result showed 94.64% accuracy in the validation set.

CONCLUSIONS

This metabolomics study revealed a distinct metabolic profile of cancer cachexia and established and validated a diagnostic model. This research provided a feasible diagnostic tool for identifying at-risk populations through the detection of serum metabolites.

Cancer Anorexia and Cachexia: Screening in an Ambulatory Infusion Service and Nutrition Consultation

BACKGROUND

Cancer anorexia-cachexia syndrome compromises physical function and nutritional and emotional well-being. Systematic screening followed by nutrition referral for appropriate interventions is rare.
.

OBJECTIVES

The purpose of this study was to pilot a screening process followed by nutritional assessment and intervention when warranted for patients with lung malignancies.
.

METHODS

Adult patients with lung malignancies were invited to complete the 12-item Anorexia/Cachexia Scale (A/CS-12) on the day of chemotherapy initiation in ambulatory infusion. Those who scored at a preset threshold were referred to nutrition services for a comprehensive assessment and intervention plan. Those who scored better than the threshold completed the A/CS-12 at each infusion visit for as many as 16 weeks. 
.

FINDINGS

90 participants enrolled, and 46 scored in a moderate-to-severe-risk category; of those, 42 were referred to nutrition services.

Malnutrition and cachexia among cancer out-patients in Nairobi, Kenya

Cancer is the third leading cause of death in Kenya. However, there is scarce information on the nutritional status of cancer patients to guide in decision making. The present study sought to assess the risk of malnutrition, and factors associated with malnutrition and cachexia, among cancer out-patients, with the aim of informing nutrition programmes for cancer management in Kenya and beyond. This was a facility-based cross-sectional study performed at Kenyatta National Hospital and Texas Cancer Centre in Nairobi, Kenya. The risk of malnutrition was assessed using the Malnutrition Universal Screening Tool (MUST). Diagnoses of malnutrition and cachexia were done using the European Society of Clinical Nutrition and Metabolism (ESPEN) and Fearon criteria, respectively. A total of 512 participants were assessed. Those at risk of malnutrition were 33·1 % (12·5 % at medium risk, 20·6 % at high risk). Prevalence of malnutrition was 13·4 %. The overall weight loss >5 % over 3 months was 18·2 % and low fat-free mass index was 43·1 %. Prevalence of cachexia was 14·1 % compared with 8·5 % obtained using the local criteria. Only 18·6 % participants had received any form of nutrition services. Age was a predictor of malnutrition and cachexia in addition to site of cancer for malnutrition and cigarette smoking for cachexia. The use of the MUST as a screening tool at the first point of care should be explored. The predictive value of current nutrition assessment tools, and the local diagnostic criteria for malnutrition and cachexia should be reassessed to inform the development of appropriate clinical guidelines and future capacity-building initiatives that will ensure the correct identification of patients at risk for timely care.

Clinical Value of Nutritional Status in Cancer: What is its Impact and how it Affects Disease Progression and Prognosis?

Malnutrition is a common finding in cancer patients, which can affect disease progression and survival. This review aims to critically summarize the prognostic role of nutritional status, from Body Mass Index (BMI) and weight loss to nutrition screening tools and biochemical indices, in cancer patients. According to the currently available data, Prognostic Nutritional Index (PNI) was a significant prognostic factor of patients' survival, both in univariate and multivariate analyses. Pre-operative albumin was also correlated with worse outcomes, being an independent prognostic factor of survival in several studies. BMI was also well-studied, with contradictory results. Although, lower BMI was found to be an independent prognostic factor of shorter survival in some studies, in others it did not have an impact on survival. In this aspect, this review highlights the significant prognostic role of nutritional status in the disease progression and survival of cancer patients. Further, good-quality prospective studies are needed in order to draw precise conclusions on the prognostic role of specific nutritional assessment tools, and biochemical indices associated with the nutritional status in more cancer types, such as liver, breast and prostate cancer, and hematological malignancies.

Protein calorie malnutrition, nutritional intervention and personalized cancer care

Cancer patients often experience weight loss caused by protein calorie malnutrition (PCM) during the course of the disease or treatment. PCM is expressed as severe if the patient has two or more of the following characteristics: obvious significant muscle wasting, loss of subcutaneous fat; nutritional intake of <50% of recommended intake for 2 weeks or more; bedridden or otherwise significantly reduced functional capacity; weight loss of >2% in 1 week, 5% in 1 month, or 7.5% in 3 months. Cancer anorexia-cachexia syndrome (CACS) is a multifactorial condition of advanced PCM associated with underlying illness (in this case cancer) and is characterized by loss of muscle with or without loss of fat mass. Cachexia is defined as weight loss of more than 5% of body weight in 12 months or less in the presence of chronic disease. Hence with a chronic illness on board even a small amount of weight loss can open the door to cachexia. These nutritional challenges can lead to severe morbidity and mortality in cancer patients. In the clinic, the application of personalized medicine and the ability to withstand the toxic effects of anti-cancer therapies can be optimized when the patient is in nutritional homeostasis and is free of anorexia and cachexia. Routine assessment of nutritional status and appropriate intervention are essential components of the effort to alleviate effects of malnutrition on quality of life and survival of patients.

Nutritional status of cancer outpatients using scored patient generated subjective global assessment in two cancer treatment centers, Nairobi, Kenya

Background

Malnutrition is a universal problem in cancer patients renowned as an important factor for increased morbidity, decreased quality of life and high mortality. Early diagnosis of malnutrition risk through nutrition screening followed by comprehensive and timely interventions reduces mortality associated with malnutrition. The Scored Patient-Generated Subjective Global Assessment (PGSGA) method has been proved efficient in identifying cancer patients with nutrition challenges and guiding appropriate interventions. However this tool has not been adopted in management of cancer patients in Kenya. The aim of the study was to assess and describe nutrition status of cancer outpatients receiving treatment at Kenyatta National Hospital Hospital (KNH) and Texas Cancer Centre (TCC).

Methods

The study adopted a hospital based descriptive cross sectional study. Cancer outpatients with confirmed stage 1–4 cancers, physically stable, aged 18 years and above and receiving cancer treatment were recruited and assessed using Scored PGSGA tool. Proportions, measures of central tendency and pearsons’ chi-square test were used in statistical analysis.

Results

Among the 471 participants assessed, 71.8% were female and 28.2% male. Most participants had stage 2, 3 and 4 cancers at 27.2%, 27.2% and 24.3% respectively. Highest proportion of participants had breast (29.7%) and female genital cancers (22.9%). Sixty nine percent of participants were well nourished (SGA-A), 19.7% moderately malnourished (SGA-B) and 11.3% severely malnourished (SGA-C) and this difference was statistically significant. The mean PGSGA score was 6.76 (SD 5.17). Based on the score, 33.8% of participants required critical nutrition care, 34.8% symptoms management, 14.2% constant nutrition education and pharmacological intervention while 17.2% required routine assessments and reassurance. More (m;54.7%, f; 45.3%) males than females were severely malnourished(SGA-C) and this was statistically significant (P < 0.001).Prevalence of severe malnutrition was highest among participants with digestive organ cancers (49.1%) followed by those with lip cancer (17%) and the least prevalence reported in those with Karposi Sarcoma (0%). Most of stage 4 participants were moderately (37.5%) and severely (29.4%) malnourished.

Conclusions

The Scored Patient-Generated Subjective Global Assessment is able to identify cancer patients both at risk of malnutrition and those severely malnourished. It also provides a guideline on the appropriate nutrition intervention hence an important tool in nutrition management of cancer patients.

Optimal Nutrition and Hydration Through the Surgical Treatment Trajectory

OBJECTIVES

To review oncology nurses role of informational continuity in regards to nutrition and hydration to ensure continuity of care from one care center to another.

DATA SOURCES

Peer-reviewed literature, PubMed, CINAHL, EMBASE, and web-based resources.

CONCLUSION

Optimal nutrition and hydration during cancer treatment and survivorship requires assessment and preplanning of needs. Oncology nurses play a vital role in preparing patients and caregivers for optimal nutrition during the surgical treatment trajectory.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses should emphasize nutrition planning during the surgical treatment trajectory to enhance survivorship and quality of life of the cancer patient. Educational resources exist for both nursing and cancer patients.

Association of nutritional status-related indices and chemotherapy-induced adverse events in gastric cancer patients

Background

Malnutrition in gastrectomized patients receiving chemotherapy is associated with the susceptibility to chemotherapy-related adverse events. This study evaluated pre-operative nutritional status-related indices associated with adverse events in post-operation gastric cancer patients receiving chemotherapy.

Methods

Medical records of 234 gastrectomized patients under adjuvant tegafur/gimeracil/oteracil chemotherapy with extended lymph node dissection were analyzed. Nutritional status assessment included Patient-Generated Subjective Global Assessment (PG-SGA), body weight, body mass index, serum albumin concentration, and Nutrition Risk Index (NRI). Chemotherapy-originated adverse events were determined using Common Terminology Criteria for Adverse Events.

Results

PG-SGA indicated 59% of the patients were malnourished, and 27.8% of the patients revealed serious malnutrition with PG-SGA score of ≥9. Fifteen % of patients lost ≥10% of the initial body weight, 14.5% of the patients had hypoalbuminemia (<3.5 g/dL), and 66.2% had NRI score less than 97.5 indicating moderate to severe malnutrition. Hematological adverse events were present in 94% (≥grade 1) and 16.2% (≥grade 3). Non-hematological adverse events occurred in 95.7% (≥grade1) and 16.7% (≥grade 3) of the patients. PG-SGA and NRI score was not associated with treatment-induced adverse events. Multivariate analyses indicated that female, low body mass index, and hypoalbuminemia were independent risk factors for grade 3/4 hematological adverse events. Age was an independent risk factor for grade 3/4 non-hematological adverse events. Neutropenia was the most frequently occurring adverse event, and associated risk factors were female, total gastrectomy, and hypoalbuminemia.

Conclusions

Hypoalbuminemia, not PG-SGA or NRI may predict chemotherapy-induced adverse events in gastrectomized cancer patients.

The Efficacy of Oral Nutritional Intervention in Malnourished Cancer Patients: a Systemic Review

Cancer is currently a leading cause of deaths worldwide and the number of new cases is growing rapidly in both, developed and developing countries. Nutritional management during and after cancer treatment affects treatment efficacy and patient quality of life (QOL). This review systemically examined the effect of oral nutritional interventions on nutritional and clinical outcomes in cancer patients. We especially focused on outcomes such as nutritional status indices, immune-associated biochemical markers, and QOL assessments to provide insights on the applicability of different outcomes. A total of 28 papers were selected for systematic review. The nutritional composition of oral nutritional supplements (ONS), outcome measures, and efficacy of the oral nutritional interventions were summarized and discussed. Most ONS contain 1 or more functional components in addition to basic nutrients. Each study used various outcome measures and significant efficacy was observed for a limited number of measures. Nutritional status indices, QOL measures, and the duration of hospital stay improved in about 40% of the studies. One or more markers of immune function and inflammatory responses were improved by ONS in 65% of the selected studies. These results suggest that appropriate use of ONS may be an ideal way to improve treatment efficacy; however, additional intervention trials are required to confirm these findings.

Assessment of Body Composition in a Group of Pediatric Patients With Cancer: A Single Romanian Center Experience

Cancer patients are particularly susceptible to nutritional depletion. From March 2014 to December 2015, we assessed 146 patients consecutively hospitalized in a tertiary emergency pediatric hospital. The patients were divided into 2 groups: group I, patients with cancer (43 patients), and group II, the control group consisting of 103 age-matched and sex-matched healthy patients. The anthropometric parameters (weight-W, height-H, body mass index [BMI], middle upper arm circumference [MUAC], tricipital skinfold thickness [TST]) and biochemical parameters (proteins, albumin) were comparatively evaluated. Fat mass (FM, kg and %), fat-free mass (FFM, kg), muscle mass (MM, kg), and total body water (TBW, %) were measured in both groups using Tanita BC 420 S MA Analyzer. Anthropometric and biochemical parameters in group I were significantly different from those in group II for weight, height, BMI, MUAC, TST, protein, and albumin (P<0.05). In the study group, FM was much lower compared with controls 16.9% (3.4% to 33.3%) versus 20.3% (6.6% to 38.4%); (P=0.001), and TBW was much higher 60.8% (48.8% to 70.6%) versus 58.5% (45.2% to 68.6%) (P=0.004). FFM and MM were not statistically different in the 2 groups. The results highlight the complex changes of nutritional status in pediatric patients with cancer.

Oral administration of an aqueous extract from the oyster mushroom Pleurotus ostreatus enhances the immunonutritional recovery of malnourished mice

Mushroom nutriceutical components have lately attracted interest for developing immunonutritional support. However, there is relatively little information pertaining to the use of mushroom preparations for modulating the metabolic and immunological disorders associated to malnutrition. This study was aimed to evaluate the effects of oral administration of an aqueous extract (CW-P) from Pleurotus ostreatus on the recovery of biochemical and immunological functions of malnourished mice. 8-week old female BALB/c mice were starved for 3days and then refed with commercial diet supplemented with or without CW-P (100mg/kg) for 8days. Regardless of the diet used during refeeding, animal body weights and serum protein concentrations did not differ between groups. Oral treatment with CW-P normalized haemoglobin levels, liver arginase and gut mucosal weight. CW-P increased total liver proteins and also DNA and protein contents in gut mucosa. Pleurotus extract provided benefits in terms of macrophages activation as well as in haemopoiesis, as judged by the recovery of bone marrow cells and leukocyte counts. Moreover, CW-P stimulated humoral immunity (T-dependent and T non-dependent antibodies responses) compared to non-supplemented mice. CW-P extract from the oyster mushroom can be used to develop specific food or nutritional supplement formulations with potential clinical applications in the immunotherapy.

Use of Hospital-Based Food Pantries Among Low-Income Urban Cancer Patients

To examine uptake of a novel emergency food system at five cancer clinics in New York City, hospital-based food pantries, and predictors of use, among low-income urban cancer patients. This is a nested cohort study of 351 patients who first visited the food pantries between October 3, 2011 and January 1, 2013. The main outcome was continued uptake of this food pantry intervention. Generalized estimating equation (GEE) statistical analysis was conducted to model predictors of pantry visit frequency. The median number of return visits in the 4 month period after a patient's initial visit was 2 and the mean was 3.25 (SD 3.07). The GEE model showed that younger patients used the pantry less, immigrant patients used the pantry more (than US-born), and prostate cancer and Stage IV cancer patients used the pantry more. Future long-term larger scale studies are needed to further assess the utilization, as well as the impact of food assistance programs such as the this one, on nutritional outcomes, cancer outcomes, comorbidities, and quality of life. Cancer patients most at risk should be taken into particular consideration.

Nutritional Care of Gastric Cancer Patients with Clinical Outcomes and Complications: A Review

The incidence and mortality of gastric cancer have been steadily decreased over the past few decades. However, gastric cancer is still one of the leading causes of cancer deaths across many regions of the world, particularly in Asian countries. In previous studies, nutrition has been considered one of significant risk factors in gastric cancer patients. Especially, malnourished patients are at greater risk of adverse clinical outcomes (e.g., longer hospital stay) and higher incidence of complications (e.g., wound/infectious complications) compared to well-nourished patients. Malnutrition is commonly found in advanced gastric cancer patients due to poor absorption of essential nutrients after surgery. Therefore, nutritional support protocols, such as early oral and enternal feeding, have been proposed in many studies, to improve unfavorable clinical outcomes and to reduce complications due to delayed application of oral nutritional support or parental feeding. Also, the supplied with enternal immune-enriched diet had more benefits in improving clinical outcomes and fewer complications compared to a group supplied with control formula. Using nutritional screening tools, such as nutritional risk index (NRI) and nutritional risk screening (NRS 2002), malnourished patients showed higher incidence of complications and lower survival rates than non-malnourished patients. However, a long-term nutritional intervention, such as nutritional counseling, was not effective in the patients. Therefore, early assessment of nutritional status in patients using a proper nutritional screening tool is suggested to prevent malnutrition and adverse health outcomes. Further studies with numerous ethnic groups may provide stronger scientific evidences in association between nutritional care and recovery from surgery in patients with gastric cancer.

Underrecognition of Malnutrition in Advanced Cancer: The Role of the Dietitian and Clinical Practice Variations

INTRODUCTION

Malnutrition (MN) often goes unrecognized due to ineffective screening techniques. Published standards for multidisciplinary care exist but no consensus on best nutritional assessment for hospitalized patients. Malnutrition is common in cancer and adversely affects clinical outcomes. The Cleveland Clinic Nutrition Therapy Department used in-house criteria to classify MN in hospitalized patients. This study aimed to evaluate the registered dietitian (RD)'s role, the use of these criteria in the acute care palliative medicine unit (ACPMU), and investigate MN prevalence and severity among admitted patients with cancer.

METHODS

Electronic medical records were reviewed for newly admitted patients with cancer to the ACPMU with a first time RD consult and completed nutritional therapy assessment. Physician (MD) assessments were derived from admission notes. Cox regression model assessed the association of MN prevalence and severity with survival. McNemar's test determined whether a prevalence difference existed between RD and MD.

RESULTS

Variations existed in criteria used to identify MN. Seventy percent had MN, with the majority (61%) classed as moderate to severe. Prevalence (hazard ratio [HR]: 1.88; P = .002) and severity (HR: 1.22; P = .006) were associated with significantly increased mortality. Evaluations by RD and MD were highly congruent, but MDs underrecorded nutritional status.

CONCLUSION

Malnutrition was prevalent and clinically important, even in those on nutritional support. Variations in MN identification were common. Physicians underrecorded MN but were accurate for prevalence and severity when recorded. The data confirm the RD's important role in MN assessment. Comparable clinical practice and better communication between physicians and dietitians should improve cancer care and optimize quality of life.

Obesity and colorectal cancer: molecular features of adipose tissue

The huge part of population in developed countries is overweight or obese. Obesity is often determined by body mass index (BMI) but new accurate methods and ratios have recently appeared to measure body fat or fat located in the intestines. Early diagnosis of obesity is crucial since it is considered an increasing colorectal cancer risk factor. On the one hand, colorectal cancer has been strongly associated with lifestyle factors. A diet rich in red and processed meats may increase colorectal cancer risk; however, high-fiber diets (grains, cereals and fruits) have been associated with a decreased risk of colorectal cancer. Other life-style factors associated with obesity that also increase colorectal cancer risk are physical inactivity, smoking and high alcohol intake. Cutting-edge studies reported that high-risk transformation ability of adipose tissue is due to production of different pro-inflammatory cytokines like IL-8, IL-6 or IL-2 and other enzymes like lactate dehydrogenase (LDH) and tumour necrosis factor alpha (TNFα). Furthermore, oxidative stress produces fatty-acid peroxidation whose metabolites possess very high toxicities and mutagenic properties. 4-hydroxy-2-nonenal (4-HNE) is an active compounds that upregulates prostaglandin E2 which is directly associated with high proliferative colorectal cancer. Moreover, 4-HNE deregulates cell proliferation, cell survival, differentiation, autophagy, senescence, apoptosis and necrosis via mitogen-activated protein kinase (MAPK), phosphoinositide 3-kinase (PIK3CA)—AKT and protein kinase C pathways. Other product of lipid peroxidation is malondialdehyde (MDA) being able to regulate insulin through WNT-pathway as well as having demonstrated its mutagenic capability. Accumulation of point mutation enables genomic evolution of colorectal cancer described in the model of Fearon and Vogelstein. In this review, we will summarize different determination methods and techniques to assess a truthfully diagnosis and we will explain some of the capabilities that performs adipocytes as the largest endocrine organ.

Incidence and risk factor analysis for sarcopenia in patients with cancer

The objective of the present study was to investigate the incidence of and possible risk factors associated with sarcopenia among cancer patients. Patients with cancer were examined through the use of lumbar magnetic resonance imaging, and clinical data was collected between September and December, 2012, at Jilin Province Tumor Hospital (Changchun, China). The data was subsequently compared between patients with and without sarcopenia. Of the 113 treated cancer patients, 96 patients [39 males (L3 index, <52.4 cm²/m²) and 57 females (L3 index, <38.5 cm²/m²)] suffered from sarcopenia. Overall, the development of sarcopenia was not significantly associated with patient age or treatment, including surgery, chemotherapy or radiotherapy (P>0.05). The frequency of treatment-associated complications did not differ significantly between patients with or without sarcopenia. However, males were more inclined to develop sarcopenia than females (P=0.02). Patients with sarcopenia had significantly less lymphocytes than patients without sarcopenia (P=0.03). This was confirmed through multiple logistic regression analyses (P=0.046), which also identified that patients with cancer with an Eastern Cooperative Oncology Group score >2 had a significantly increased risk of developing sarcopenia. Finally, the serum albumin level in sarcopenia patients was 36.18±4.65 g/l, which was not significantly less than that of patients without sarcopenia (39.67±3.69 g/l; P=0.11). The incidence of sarcopenia among patients with cancer is high, particularly for males. Further research with larger sample sizes would be beneficial, with the aim of verifying the results obtained in the present study. During the treatment of patients with sarcopenia, precaution should continue to be taken to prevent associated complications, including infection, diarrhea and myelosuppression.

Childhood cancer in Gondar University Hospital, Northwest Ethiopia

Background

Childhood cancer becomes a public health problem in developing countries which aggravates the burden of childhood mortality by infectious diseases and malnutrition. In poor countries, the death rate for most pediatric cancers is almost 100 %. This study attempts to determine the magnitude, patterns and trends of pediatric malignancies in the study area which is important in re-evaluating existing services and in improving facilities and patient care.

Methods

A retrospective study of 3 year period were carried out among all children aged below 15 years old admitted into the pediatric wards of Gondar University Hospital, Northwest Ethiopia. The charts of all children aged below 15 years old admitted in the pediatric wards due to cancer were reviewed by using the data collection format. Data were entered and analyzed using SPSS version 20 statistical package.

Result

A total of 71 cancer cases were diagnosed and admitted to the pediatrics ward during the study period. More than two-third of the study subjects 50 (70.4 %) were males. The mean age of study subjects was 7 ± 4 year where majority 26 (36.6 %) of the study subjects were ≥10 years. Of all, 43 (60.6 %) were hematological malignancy followed by Wilms tumor 13 (18.3 %), Neuroblastoma 5 (7 %), Rhabdomyosarcoma 3 (4.2 %), Brain tumor 3 (4.2 %), Hepatoblastoma 2 (2.8 %). More than two-third of cases were found to be concomitantly malnourished being stunted, wasted and under weight. Nearly half of patients had not received chemotherapy and majority of those started chemotherapy did not complete all the treatment cycles. Shortage and absence of safe and affordable chemotherapy drugs were the major reasons for therapy interruption.

Conclusion

The study shows increasing childhood cancer cases over the years. Hematological malignancy takes the leading prevalence followed by Wilms tumor and Neuroblastoma. The majority of cases were also discharged without any clinical change that had the only death option. Therefore, the government and the hospital should give emphasis to establish cancer therapy centers and insure accessibility and affordability of chemotherapy drugs.

Outcomes of Iatrogenic Genitourinary Injuries During Colorectal Surgery

OBJECTIVE

To describe, categorize, and determine the outcomes of repairs of genitourinary (GU) injuries that occur during colorectal surgery. Presently, little is known regarding these injuries or the long-term outcomes of their repair.

METHODS

We performed a retrospective review of patients undergoing colorectal surgery between 2003 and 2013 who experienced iatrogenic GU injuries requiring surgical repair. GU repair failures were defined as development of urine leak, urinary fistula, or anastomotic stricture requiring secondary GU intervention. Possible risk factors associated with repair failures were examined and included age, American Society of Anesthesiology score, comorbidities, type of colorectal surgery, radiation, and chemotherapy.

RESULTS

Of 42,570 colorectal surgeries performed, 75 GU injuries were identified (0.18%). Mean age was 57.5 years (range, 22-91), and median follow-up was 19.5 months (range, 1-128). Fifty-nine (59/75, 79%) patients required a single GU repair whereas 16 of 75 (21%) patients experienced repair failure requiring additional GU intervention. The most common GU injuries were cystotomy (26/75, 35%), incomplete ureteral transection (22/75, 29%), complete proximal and distal ureteral injuries (13/75, 17%; 11/75, 15%), urethral injury (2/75, 3%), and injury to a pre-existing ileal conduit (1/75, 1). Twenty-seven patients (36%) had prior radiation and 35 patients (47%) had prior chemotherapy. Preoperative radiation and chemotherapy were both associated with failure of the GU repair (P = .003; P = .013). Delayed repair of the GU injury was also associated with repair failure (P = .001).

CONCLUSION

Iatrogenic GU injuries during colorectal surgery are rare, affecting only 0.18% of colorectal procedures. Preoperative external beam radiation therapy/chemotherapy and delayed GU repair are associated with worse outcomes of repairs of these injuries.

Understanding and managing cancer-related weight loss and anorexia: insights from a systematic review of qualitative research

The aim of this study was to summarize the existing qualitative literature in order to develop the evidence base for understanding and managing weight loss and anorexia, in order to make recommendations for clinical practice. A systematic search was performed to retrieve English language studies using electronic search and manual checks of selected reference lists. Keywords included qualitative, cancer cachexia, weight loss, anorexia, appetite, malnutrition, food, eating, and drinking. The selection and appraisal of papers were undertaken by two reviewers. Twenty-one qualitative articles were included in the review. There were three major findings emerging from the previous qualitative studies including 'the multidimensionality of weight loss and anorexia experience', 'patients and caregivers' responses to coping with weight loss and anorexia', and 'clinical assessment and management of weight loss and anorexia'. The literature review revealed the multidimensional nature of cachexia and weight loss experience by patients and caregivers, which was not recognized and adequately managed by healthcare professionals. Future research in this area would be helpful in enabling a deeper understanding of the complexity of cachexia and weight loss experience in order to move forward to develop an optimal model of supportive care for patients and caregivers.

Integrated analysis of serum and intact muscle metabonomics identify metabolic profiles of cancer cachexia in a dynamic mouse model

An integrated analysis of 13 metabolites from the intact muscle gastrocnemius and 43 metabolites from the serum reveals five distinguishable metabolic features of cancer cachexia.

Nutrient intake and nutritional status of newly diagnosed patients with cancer from the East Coast of Peninsular Malaysia

BACKGROUND

Cancer therapy in Malaysia primarily focuses on the clinical management of patients with cancer and malnutrition continues to be one of the major causes of death in these patients. There is a dearth of information on the nutrient intake and status of newly diagnosed patients with cancer prior to the initiation of treatment. The present study aims to assess the nutrient intake and status of newly diagnosed patients with cancer from the East Coast of Peninsular Malaysia.

METHODS

A cross-sectional study was conducted using a convenient sample of newly diagnosed adult patients with cancer (n = 70) attending the Oncology clinic, Hospital Universiti Sains Malaysia in the East Coast of Peninsular Malaysia. Information on socio-demographic characteristics, clinical status, anthropometry, dietary intake and biochemical data including blood samples was obtained.

RESULTS

The mean (SD) age, triceps skin fold (TSF), mid upper arm circumference (MUAC) and body mass index (BMI) of participants was 21.1(3.9) years, 17.6(7.9) mm, 24.1(5.5) cm, and 21.1(3.9) Kg/m(2), respectively; 39% participants had BMI <18.5 Kg/m(2). One-third of newly diagnosed patients with cancer were undernourished (i.e. women: MUAC <220 mm; men: <230 mm). The proportion (%) of participants with low haemoglobin (<120 g/L) and serum albumin (<38 g/dL) were 62% and 26%, respectively. The older women had significantly lower macro and micro nutrient intakes compared to men in the same age group (P <0.05).

CONCLUSIONS

At the time of diagnosis, greater than one-third of patients with cancer from the East Coast of Peninsular Malaysia were underweight and undernourished. The majority of patients with cancer had poor micronutrient intakes; the older women had a poor macro and micronutrient intakes. Before the initiation of rigorous clinical management of patients with cancer, screening for nutritional status, subsequent nutrition counseling, and interventions are essential to improve their nutritional status; consequently, response to cancer therapy, survival and quality of life.

Effects of an oral nutritional supplement containing eicosapentaenoic acid on nutritional and clinical outcomes in patients with advanced non-small cell lung cancer: randomised trial

BACKGROUND

Nutritional interventions have shown increased energy intake but not improvement in health-related quality of life (HRQL) or prognosis in non small cell lung cancer (NSCLC) patients. Eicosapentaenoic acid has been proposed to have anti-inflammatory, anticachectic and antitumoural effects.

OBJECTIVE

To compare the effect of an oral EPA enriched supplement with an isocaloric diet on nutritional, clinical and inflammatory parameters and HRQL in advanced NSCLC patients.

DESIGN

Patients with advanced NSCLC were randomized to receive diet plus oral nutritional supplement containing EPA (ONS-EPA) or only isocaloric diet (C). All patients received paclitaxel and cisplatin/carboplatin treatment. Weight, body composition, dietary intake, inflammatory parameters and HRQL were assessed at baseline and after the first and second cycles of chemotherapy. Response to chemotherapy and survival were evaluated.

RESULTS

Ninety two patients were analysed (46 ONS-EPA,46 C). ONS-EPA group had significantly greater energy (p < 0.001) and protein (p < 0.001) intake compared with control. Compared with baseline, patients receiving the ONS-EPA gained 1.6 ± 5 kg of lean body mass (LBM) compared with a loss of -2.0 ± 6 kg in the control (p = 0.01). Fatigue, loss of appetite and neuropathy decreased in the ONS-EPA group (p ≤ 0.05). There was no difference in response rate or overall survival between groups.

CONCLUSION

Patients with NSCLC receiving ONS-EPA significantly improves energy and protein intake, body composition. and decreased fatigue, loss of appetite and neuropathy. Registered with ClinicalTrials.gov (NCT01048970).

Decision-making in patients with cancer and kidney disease

Thoughtful decision-making in a patient with cancer and kidney disease requires a comprehensive discussion of prognosis and therapy options for both conditions framed by the individual's preferences and goals of care. An estimate of overall prognosis is generated that includes the patient's clinical presentation and parameters associated with adverse outcomes, such as age, performance status, frailty, malnutrition, and comorbidities. Empathic communication of this information using a shared decision-making approach can lead to an informed decision that respects patient autonomy and is consistent with the patient's "big-picture" goals and personal values.

The association between malnutrition and psychological distress in patients with advanced head-and-neck cancer

OBJECTIVE

Malnutrition and psychological distress are often seen in patients with head-and-neck cancer, but little is known about the interrelationships between those two symptoms. The present study examined the relationship between malnutrition and psychological distress in patients with advanced head-and-neck cancer.

METHODS

Using the Patient-Generated Subjective Global Assessment, 99 patients with advanced-stage head-and-neck cancer were screened for nutrition status. The patients were also screened for psychosocial distress (using the Distress Thermometer) and for psychosocial issues (using the Problem Checklist). Any relationship between malnutrition and psychosocial distress was determined by regression and correlation analysis. We also used t-tests to compare distress levels for patients with and without specific nutrition-related symptoms.

RESULTS

The study group included 80 men and 19 women [mean age: 58.4 ± 10.9 years (range: 23-85 years)]. The correlation between poorer nutrition status and level of psychological distress was significant r = 0.37 (p < 0.001). Specifically, reduced food intake and symptoms were both positively associated with distress: r = 0.27 and r = 0.29 respectively, both significant at p < 0.01. After controlling for the effects of psychosocial problems and pain, nutrition status remained a significant predictor of distress, explaining 3.8% of the variance in the distress scores of the patients (p < 0.05).

CONCLUSIONS

Malnutrition and symptoms were strongly related to distress in patients with advanced head-and-neck cancer. Our results suggest the need for further research into the complex relationship between nutrition status and distress and into the management of both nutrition and distress in cancer care.

Validation of nutritional risk index method against patient-generated subjective global assessment in screening malnutrition in colorectal cancer patients

OBJECTIVE

To validate malnutrition screening tool of nutrition risk index (NRI) against patient-generated subjective global assessment (PG-SGA) as a gold standard tool in colorectal cancer patients before radiotherapy.

METHODS

Nutritional status of 52 volunteer colorectal cancer patients with a mean age of 54.1±16.8 years who referred to radiotherapy center were assessed by PG-SGA (gold standard method) and NRI. Serum albumin levels of patients were determined by colorimetric method. A contingency table was used to determine the sensitivity, specificity, and predictive value of the NRI in screening patients at risk of malnutrition, in comparison with the PG-SGA in patients before radiotherapy.

RESULTS

The findings of PG-SGA and NRI showed that 52% and 45% of patients in our study were moderately or severely malnourished respectively. The NRI had a sensitivity of 66% and a specificity of 60% against PG-SGA. The positive predictive value was 64% and the negative predicative value was 62%. The agreement between NRI and PG-SGA was statistically insignificant (kappa =0.267; P>0.05).

CONCLUSIONS

The findings of present study showed that the prevalence of malnutrition was high in patients with colorectal cancer. Moreover, NRI method had low sensitivity and specificity in assessing nutritional status of patients with cancer. It seems that the combination of anthropometric, laboratory parameters and a subjective scoring system may be helpful tools in screening of malnutrition in cancer patients.

Home artificial nutrition: an update seven years after the regional regulation

BACKGROUND & AIMS

Home Artificial Nutrition (HAN) is a well established extra-hospital therapy, contributing to decreased health care costs, by reducing the number and length of hospitalizations. The knowledge of the epidemiology of HAN helps plan health-care funding and in analyze the factors that can improve HAN service.

SUBJECTS AND METHODS

An update on the prevalence of Home Artificial Nutrition (HAN) in the Campania region (Southern Italy) and patients clinical characteristics has been regularly carried out in the past seven years after a specific regional regulation issued in 2005.

RESULTS

Total number of patients on HAN has increased from 355 in April 2005 to 1165 in April 2012 (+228.2%); in particular, patients on Home Parenteral Nutrition (HPN) increased from 156 in April 2005 to 306 in April 2012 (+96.2%) and patients on Home Enteral Nutrition (HEN) from 199 to 838 (+321.1%) respectively. HEN/HPN ratio in adults has changed from 1.3/1 in April 2005 to 2.7/1 in April 2012, gradually nearing the expected national mean ratio of 5/1 as observed in the 2005 national survey.

CONCLUSIONS

The specific regional regulation in Campania has contributed to increase the prescription of HAN and to ameliorate its indications; in particular, through the years, HEN is gradually nearing national standards.

Comparison of the prognostic values of various nutritional parameters in patients with esophageal squamous cell carcinoma from Southern China

BACKGROUND

Nutritional evaluation is important for patients with esophageal cancer, but the impact of undernutrition on outcome of those patients is not well elucidated. Our aim is to assess the impact of baseline nutritional status on overall survival (OS) in Chinese patients with esophageal squamous cell carcinoma (ESCC) and to detect a most appropriate indicator for nutritional evaluation.

METHODS

502 patients from Southern China diagnosed as ESCC in Sun Yat-Sen University Cancer Center were included. A series of nutritional indicators were introduced to evaluate the baseline nutritional status. Kaplan-Meier method was used to estimate the 5-year OS and the log-rank test was used to determine the survival differences. Cox proportional hazards model was used in the univariate and multivariate analyses of OS.

RESULTS

With a median follow up time of 30 months, the median OS for the entire patient group was 37.3 months with the 5-year OS rate of 43.0%. Only performance status, AJCC 6th stage and body mass index (BMI) were the independent prognostic factors in multivariate analysis of OS. The median OS for patients with BMI less than 18.5, patients with BMI within 18.5-24.9 and patients with BMI more than 24.9 were 19.2, 43.2 and 51.6 months, respectively, with the 5-year OS rates of 25.2%, 46.1% and 48.1% (P<0.001). Patients with BMI <18.5 tended to present with a more advanced stage disease and a poorer tumor grade.

CONCLUSIONS

Baseline nutritional status is predictive of OS in Chinese patients with ESCC. BMI is a steady indicator for nutritional evaluation and a sensitive prognostic parameter for ESCC patients. Treatment optimization in ESCC patients with low BMI should integrate the modalities and individual nutritional support.

Chronic radiation enteritis and malnutrition

Radiation enteritis is defined as the loss of absorptive capacity of the intestine following irradiation, which is most commonly seen after radiotherapy for pelvic and abdominal malignancies. It is divided into acute and chronic forms and usually presents with diarrhea and malabsorption. Malnutrition is a common complication of chronic radiation enteritis (CRE). We reviewed the etiology, prevalence, symptoms, diagnosis and management of CRE and CRE with malnutrition in this article. Functional short bowel syndrome as a cause of malnutrition in CRE is also considered. The diagnostic work-up includes serum markers, endoscopy, cross-sectional imaging and the exclusion of alternative diagnoses such as recurrent malignancy. Management options of CRE include dietary manipulation, anti-motility agents, electrolyte correction, probiotics, parenteral nutrition, surgical resection and small bowel transplantation. Treatment may also be required for coexisting conditions including vitamin B12 deficiency, bile acid malabsorption and depression.

Highlights of mechanistic and therapeutic cachexia and sarcopenia research 2010 to 2012 and their relevance for cardiology

Sarcopenia and cachexia are significant medical problems with a high disease-related burden in cardiovascular illness. Muscle wasting and weight loss are very frequent particularly in chronic heart failure and they relate to poor prognosis. Although clinically largely underestimated, the fields of cachexia and sarcopenia are of great relevance to cardiologists. In cachexia and sarcopenia a significant number of research publications related to basic science questions of muscle wasting and lipolysis were published between 2010 and 2012. Recently, the two processes of muscle wasting and lipolysis were found to be closely linked. Treatment research in pre-clinical models involves studies on a number of different therapeutic entities, including ghrelin, selective androgen receptor modulators (SARMs), as well as drugs targeting myostatin or melanocortin-4. In the human setting, studies using enobosarm (a SARM) and anamorelin (ghrelin) are in phase III. The last 3 years have seen significant efforts to define the field using consensus statements. In the future, these definitions should also be considered for guidelines and treatment trials in cardiovascular medicine. The current review aims to summarize important information and development in the fields of muscle wasting, sarcopenia and cachexia, focusing on findings in cardiovascular research, in order for cardiologists to have a better understanding of the progress in this still insufficiently known field.
