ABSTRACT
PURPOSE OF REVIEW: Existing definitions of clinically important weight loss in patients with cancer do not specifically address weight loss in patients who are obese at presentation. This review explores the clinical impact of weight loss and depletion of the skeletal muscle mass (i.e., criteria defining cancer cachexia), in patients with obesity. RECENT FINDINGS: Overweight and obese BMI values are shown by many recent studies to pose a survival advantage in patients with cancers of advanced stage, when compared with BMI in normal and underweight ranges. The classification of cancer-associated weight loss has evolved, and current grading schemes evaluate the impact of weight across the range of BMI values. Weight loss is associated with mortality in patients with BMI more than 30âkg/m 2 , however this is to a much lesser degree than in patients with lower BMI values. Diagnostic imaging permits the precise assessment of skeletal muscle index (SMI) in patients with cancer, and it has been clearly shown that while usually quite muscular, obese patients can have profound muscle depletion (i.e., sarcopenia), independent of the presence of weight loss. Muscle depletion associates strongly with mortality in obese patients, as well as with complications of cancer surgery and systemic therapy. SUMMARY: It would seem contradictory to diagnose concurrent obesity and cachexia, as these terms represent opposite ends of the weight spectrum. Weight loss can occur in anyone with cancer, however its priority for clinical management may be lesser in obese versus low body weight individuals. Sarcopenic obesity is strongly associated with a poor clinical outcome and deserves further research, diagnosis in clinical practice, and new strategies for mitigation.

PURPOSE: Advanced cancer patients have nutrition impact symptoms (NISs), while many of them have depressive moods. This study aimed to determine the associations of NISs with depression. METHODS: This study was a secondary analysis. The dietary intake and 19 NISs in patients receiving palliative care were evaluated using 10-point scales, and the patients were categorized into two groups (non-depression and depression groups) using the cutoff based on the Patient Health Questionnaire-9 (PHQ-9). To determine associations between depression and the number of NISs with a score of ≥ 4, the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the logistic regression model were calculated. RESULTS: A total of 225 participants were divided into the non-depression group (n = 148) and the depression group (n = 77). The prevalence of depression was 34.2%. Dietary intake was lower, and the number of NISs with a score of ≥ 4 was higher in the depression group (both p < 0.001). All NISs were more severe in the depression group. Significant differences were observed in 15 of the 19 NISs. In the logistic regression model, significantly higher adjusted ORs were observed in the groups with 4-6 NISs and 7 or more NISs with a score of ≥ 4 (10.76 [95% CI, 2.07-55.91], p = 0.016; 17.02 [95% CI, 3.08-94.22], p < 0.001) than in the group with no NISs with a score of ≥ 4. CONCLUSION: Having four or more NISs with a score ≥ 4 was associated with depression.

Significant variation exists in the outcomes used in cancer cachexia trials, including measures of body composition, which are often selected as primary or secondary endpoints. To date, there has been no review of the most commonly selected measures or their potential sensitivity to detect changes resulting from the interventions being examined. The aim of this systematic review is to assess the frequency and diversity of body composition measures that have been used in cancer cachexia trials. MEDLINE, Embase and Cochrane Library databases were systematically searched between January 1990 and June 2021. Eligible trials examined adults (≥18 years) who had received an intervention aiming to treat or attenuate the effects of cancer cachexia for >14 days. Trials were also of a prospective controlled design and included body weight or at least one anthropometric, bioelectrical or radiological endpoint pertaining to body composition, irrespective of the modality of intervention (e.g., pharmacological, nutritional, physical exercise and behavioural) or comparator. Trials with a sample size of <40 patients were excluded. Data extraction used Covidence software, and reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance. This review was prospectively registered (PROSPERO: CRD42022276710). A total of 84 clinical trials, comprising 13 016 patients, were eligible for inclusion. Non-small-cell lung cancer and pancreatic cancer were studied most frequently. The majority of trial interventions were pharmacological (52%) or nutritional (34%) in nature. The most frequently reported endpoints were assessments of body weight (68 trials, n = 11 561) followed by bioimpedance analysis (BIA)-based estimates (23 trials, n = 3140). Sixteen trials (n = 3052) included dual-energy X-ray absorptiometry (DEXA)-based endpoints, and computed tomography (CT) body composition was included in eight trials (n = 841). Discrepancies were evident when comparing the efficacy of interventions using BIA-based estimates of lean tissue mass against radiological assessment modalities. Body weight, BIA and DEXA-based endpoints have been most frequently used in cancer cachexia trials. Although the optimal endpoints cannot be determined from this review, body weight, alongside measurements from radiological body composition analysis, would seem appropriate. The choice of radiological modality is likely to be dependent on the trial setting, population and intervention in question. CT and magnetic resonance imaging, which have the ability to accurately discriminate tissue types, are likely to be more sensitive and provide greater detail. Endpoints are of particular importance when aligned with the intervention's mechanism of action and/or intended patient benefit.

BACKGROUND & AIMS: There is no definition of nutrition impact symptoms (NISs) in cancer care. Moreover, there is a lack of evidence on the associations of NISs with dietary intake and eating-related distress (ERD) in advanced cancer. Therefore, this study aimed to determine the associations of NISs with dietary intake and ERD in patients with advanced cancer. METHODS: This study entailed a secondary analysis of a multicenter self-reported questionnaire designed to develop measurements that assess ERD experienced by patients. Participants evaluated their dietary intake and 19 symptoms regarded as NISs using a 10-point scale. To determine the association between dietary intake and the number of NISs with a score ≥4, estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the logistic regression model were calculated. Furthermore, to assess the association between ERD and the number of NISs with a score ≥4, multiple regression analysis was performed. RESULTS: A total of 302 patients were included in the analysis. The higher the number of NISs with a score ≥4, the lower the dietary intake tended to be. In the logistic regression model, significantly higher adjusted ORs than in the no NISs with a score ≥4 group were observed in the 4-6 NISs group, 7-9 NISs group, and 10 or more group (0.19 [95% CI, 0.07-0.52], p = 0.001; 0.11 [95% CI, 0.03-0.42], p = 0.001; 0.07 [95% CI, 0.01-0.36], p = 0.002, respectively). In the multiple regression analysis, the number of NISs with a score ≥4 was identified as one of the factors significantly associated with ERD. CONCLUSIONS: Having 4 or more NISs with a score ≥4 was shown to be predictive of the likelihood of reduced dietary intake. Furthermore, the higher the number of NISs with a score ≥4, the more likely the eating-related quality of life was impaired in advanced cancer.

BACKGROUND & AIMS: The international cancer cachexia criteria with a cutoff of 5% weight loss (WL) was proposed in Western patients. The Asian Working Group for Cachexia (AWGC) developed new criteria in Asian patients. The AWGC criteria are not cancer-specific and employ a cutoff of 2% WL. However, it is unclear whether both criteria are useful in patients with very advanced cancer because WL can be underestimated owing to fluid retention. Therefore, this study aimed to investigate the impacts of fluid retention on the prognostic abilities of both criteria in cancer patients with weeks of survival. METHODS: This study involved a secondary analysis of a prospective cohort study. The inclusion criteria constrained the study to adult patients with advanced cancer. Patients were divided into Non-cachexia and Cachexia groups using the international criteria and AWGC criteria. We performed time-to-event analyses using the Kaplan-Meier method and log-rank tests, and by conducting univariate and multivariate Cox regression analyses. RESULTS: A total of 402 patients were included in the analysis. Using the international criteria, the p-values for the log-rank test and stratified log-rank test for the mixed patients with and without fluid retention were 0.55 and 0.18, respectively. Using the AWGC criteria, the p-values for the log-rank test and stratified log-rank test for the mixed patients with and without fluid retention were 0.38 and 0.12, respectively. Without considering the impacts of fluid retention, no significant differences were observed between the Non-cachexia and Cachexia groups for both criteria. After adjusting for the status of fluid retention, significantly higher risks of mortality were not observed in the Cox proportional hazard model for the Cachexia group compared with the Non-cachexia group, for both criteria. However, significant associations were observed between fluid retention and overall survival. CONCLUSIONS: The international criteria and AWGC criteria lost their prognostic abilities in cancer patients with weeks of survival. Since measurements of %WL were significantly confounded by fluid retention, fluid retention-adjusted criteria for cachexia need to be developed for cancer patients with refractory cachexia.

BACKGROUND: Cancer cachexia is a severe complication of advanced malignancy, with few therapeutic options. To promote interprofessional care for cancer cachexia, healthcare providers' needs should be addressed in detail. This pre-planned subgroup analysis of the Global Educational Needs Evaluation: a systemic interprofessional study in cancer cachexia (GENESIS-CC) survey aimed to identify barriers to interprofessional care of cancer cachexia in Japan. METHODS: A nationwide survey was electronically conducted for healthcare providers in oncological or general healthcare facilities from January to March 2021 in Japan. The Japanese Regional Advisory Board developed a barrier scoring system with 33 from the 58 original survey items to quantify six domains of barriers: (1) lack of confidence, (2) lack of knowledge, (3) barriers in personal practice, (4) barriers in perception, (5) barriers in team practice and (6) barriers in education. The largest possible barrier score was set at 100 points. We compared the scores by profession. RESULTS: A total of 1227 valid responses were obtained from 302 (24.6%) physicians, 252 (20.5%) pharmacists, 236 (19.2%) nurses, 218 (17.8%) dietitians, 193 (15.7%) rehabilitation therapists and 26 (2.0%) other professionals. Overall, 460 (37.5%) were not very or at all confident about cancer cachexia care, 791 (84.1%) agreed or strongly agreed that care was influenced by reimbursement availability and 774 (81.9%) did not have cancer cachexia as a mandatory curriculum. The largest mean barrier score (± standard deviation) was 63.7 ± 31.3 for education, followed by 55.6 ± 21.8 for team practice, 43.7 ± 32.5 for knowledge, 42.8 ± 17.7 for perception and 36.5 ± 16.7 for personal practice. There were statistically significant interprofessional differences in all domains (P < 0.05), especially for pharmacists and nurses with the highest or second highest scores in most domains. CONCLUSIONS: There is a need to improve the educational system and team practices of cancer cachexia for most Japanese healthcare providers, especially pharmacists and nurses. Our study suggests the need to reform the mandatory educational curriculum and reimbursement system on cancer cachexia to promote interprofessional care for cancer cachexia in Japan.

BACKGROUND: There is a need to adopt valid techniques to assess skeletal muscle (SM) in clinical practice. SM can be precisely quantified from computed tomography (CT) images. This study describes how registered dietitians (RDs), trained to quantify SM from CT images, implemented this technique in clinical practice. METHODS: This was an explanatory sequential mixed-methods design with a quantitative and a qualitative phase. RDs collected data describing how they implemented CT SM assessments in clinical practice, followed by a focus group exploring barriers and enablers to using CT SM assessments. RESULTS: RDs (N = 4) completed 96 CT SM assessments, with most (94%, N = 90/96) taking <15 min to complete. RDs identified reduced muscle mass in 63% (N = 45/72) of men and 71% (N = 17/24) of women. RDs used results of CT SM assessments to increase protein composition of the diet/nutrition support, advocate for initiation or longer duration of nutrition support, coordinate nutrition care, and provide nutrition education to patients and other health service providers. The main barriers to implementing CT SM assessments in clinical practice related to cumbersome health system processes (ie, CT image acquisition) and challenges integrating CT image analysis software into the health system computing environment. CONCLUSION: Preliminary results suggest RDs found CT SM assessments positively contributed to their nutrition care practice, particularly in completing nutrition assessments and in planning, advocating for, and implementing nutrition interventions. Use of CT SM assessments in clinical practice requires innovative IT solutions and strategies to support skill development and use in clinical nutrition care.

Significant progress in our understanding of cancer cachexia has occurred in recent years. Despite these advances, no pharmacologic agent has achieved US Food and Drug Administration approval for this common and highly morbid syndrome. Fortunately, improved understanding of the molecular basis of cancer cachexia has led to novel targeted approaches that are in varying stages of drug development. This article reviews two major thematic areas that are driving these pharmacologic strategies, including those targeting signal mediators at the level of the CNS and skeletal muscle. Additionally, pharmacologic strategies are being tested in combination with targeted nutrients, nutrition therapy, and exercise to treat cancer cachexia. To this end, we highlight recently published and ongoing trials evaluating cancer cachexia therapies in these specific areas.

PURPOSE: Multimodal care for cancer cachexia is needed. This study examined factors associated with practicing multimodal cachexia care among physicians and nurses engaging in cancer care. METHODS: This was a preplanned secondary analysis of a survey investigating clinicians' perspectives on cancer cachexia. Data of physicians and nurses were used. Data on knowledge, skills, and confidence in multimodal cachexia care were obtained. Nine items on practicing multimodal cachexia care were evaluated. Participants were divided into two groups as practicing multimodal cachexia care (above median value for the nine items) or not. Comparisons were made using the Mann-Whitney U test or chi-square test. Multiple regression analysis was performed to identify the factors of practicing the multimodal care. RESULTS: Total of 233 physicians and 245 nurses were included. Significant differences were observed between the groups: female sex (P = .025), palliative care versus oncology specialization (P < .001), the number of clinical guidelines used (P < .001), the number of symptoms used (P = .005), training for cancer cachexia (P = .008), knowledge on cancer cachexia (P < .001), and confidence in cancer cachexia management (P < .001). Palliative care specialization (partial regression coefficient [B] = 0.85; P < .001), the number of clinical guidelines used (B = 0.44; P < .001), knowledge on cancer cachexia (B, 0.94; P < .001), and confidence in cancer cachexia management (B = 1.59; P < .001) were statistically significant in multiple regression analysis. CONCLUSION: Specialization in palliative care, specific knowledge, and confidence were associated with the practice of multimodal care for cancer cachexia.

PURPOSE OF REVIEW: Systemic cancer therapy-associated skeletal muscle wasting is emerging as a powerful impetus to the overall loss of skeletal muscle experienced by patients with cancer. This review explores the clinical magnitude and biological mechanisms of muscle wasting during systemic cancer therapy to illuminate this adverse effect. Emerging strategies for mitigation are also discussed. RECENT FINDINGS: Clinical findings include precise, specific measures of muscle loss over the course of chemotherapy, targeted therapy and immunotherapy. All these therapeutic classes associate with quantitatively important muscle loss, independent of tumor response. Parallel experimental studies provide understanding of the specific molecular basis of wasting, which can include inhibition of protein synthesis, proliferation and differentiation, and activation of inflammation, reactive oxygen species, autophagy, mitophagy, apoptosis, protein catabolism, fibrosis and steatosis in muscle. Strategies to mitigate these muscle-specific adverse effects of cancer therapy remain in the earliest stages of development. SUMMARY: The adverse side effect of cancer therapy on skeletal muscle has been largely ignored in the development of cancer therapeutics. Given the extent to which loss of muscle mass and function can bear on patients' function and quality of life, protection/mitigation of these side effects is a research priority.

BACKGROUND: Although body composition is an important determinant of pediatric health outcomes, we lack tools to routinely assess it in clinical practice. We define models to predict whole-body skeletal muscle and fat composition, as measured by dual X-ray absorptiometry (DXA) or whole-body magnetic resonance imaging (MRI), in pediatric oncology and healthy pediatric cohorts, respectively. METHODS: Pediatric oncology patients (≥5 to ≤18 years) undergoing an abdominal CT were prospectively recruited for a concurrent study DXA scan. Cross-sectional areas of skeletal muscle and total adipose tissue at each lumbar vertebral level (L1-L5) were quantified and optimal linear regression models were defined. Whole body and cross-sectional MRI data from a previously recruited cohort of healthy children (≥5 to ≤18 years) was analyzed separately. RESULTS: Eighty pediatric oncology patients (57% male; age range 5.1-18.4 y) were included. Cross-sectional areas of skeletal muscle and total adipose tissue at lumbar vertebral levels (L1-L5) were correlated with whole-body lean soft tissue mass (LSTM) (R2 = 0.896-0.940) and fat mass (FM) (R2 = 0.874-0.936) (p < 0.001). Linear regression models were improved by the addition of height for prediction of LSTM (adjusted R2 = 0.946-0.971; p < 0.001) and by the addition of height and sex (adjusted R2 = 0.930-0.953) (p < 0.001)) for prediction of whole body FM. High correlation between lumbar cross-sectional tissue areas and whole-body volumes of skeletal muscle and fat, as measured by whole-body MRI, was confirmed in an independent cohort of 73 healthy children. CONCLUSION: Regression models can predict whole-body skeletal muscle and fat in pediatric patients utilizing cross-sectional abdominal images.

Literature assessing the impact of palliative care (PC) consultation on aggressive care at the end of life (EOL) within a comprehensive integrated PC program is limited. We retrospectively reviewed patients with advanced cancer who received oncological care at a Canadian tertiary center, died between April 2013 and March 2014, and had access to PC consultation in all healthcare settings. Administrative databases were linked, and medical records reviewed. Composite score for aggressive EOL care was calculated, assigning a point for each of the following: ≥2 emergency room visits, ≥2 hospitalizations, hospitalization >14 days, ICU admission, and chemotherapy administration in the last 30 days of life, and hospital death. Multivariable logistic regression was adjusted for age, sex, income, cancer type and PC consultation for ≥1 aggressive EOL care indicator. Of 1414 eligible patients, 1111 (78.6%) received PC consultation. In multivariable analysis, PC consultation was independently associated with lower odds of ≥1 aggressive EOL care indicator (OR 0.49, 95% CI 0.38−0.65, p < 0.001). PC consultation >3 versus ≤3 months before death had a greater effect on lower aggressive EOL care (mean composite score 0.59 versus 0.88, p < 0.001). We add evidence that PC consultation is associated with less aggressive care at the EOL for patients with advanced cancer.

OBJECTIVE: We investigated the association between body composition upon diagnosis and complicated phenotypes and time until surgery in patients with Crohn's disease (CD). METHODS: We conducted a retrospective cohort study including patients with CD who had a computed tomography enterography or a magnetic resonance enterography performed ≤6 mo of diagnosis. Skeletal muscle and visceral and subcutaneous adipose tissue cross-sectional areas were determined with computed tomography or magnetic resonance images at the third lumbar vertebral level, processed with the sliceOmatic (TomoVison, Magog, QC, Canada) and ABACS plugin. RESULTS: We included 63 patients: 33 (52%) men, median age 35 y. Disease location (L) and behavior (B) according to the Montreal classification were L1 (ileal disease) = 28 (44%), L2 (colonic disease) = 13 (21%), L3(ileocolonic disease) = 18 (28%), L1 + L4 (ileal and isolated upper disease) = 1 (2%), L3 + L4 (ileocolonic and isolated upper disease) = 3 (5%), B1 (non-stricturing) = 39 (62%), B2 (stricturing) = 11 (17%), and B3 (penetrating)= 13 (21%); 20 (32%) patients had perianal disease. Visceral obesity was present in 12 (19%) patients and was associated with higher age of CD onset (median 60 versus 34 y; P = 0.002) and complicated disease behavior (B2 and B3) (66.7% versus 31.7%; P = 0.021). After adjusting for age and perianal disease, total adipose tissue was associated with a 4% increase in the odds of complicated behavior per 10 cm2 of total adipose tissue (odds ratio [OR] = 1.004; 95% confidence interval [CI], 1.00-1.008; P = 0.043). Median follow-up time was 3.35 y, during which 15 (24%) of patients underwent abdominal surgery. Visceral obesity was associated with 5.10-times higher risk of abdominal surgery (95% CI, 1.52-17.09; P = 0.008); after adjusting for disease behavior, visceral obesity maintained a near-significant association with a 2.90-times higher risk of surgery (95% CI, 0.83-10.08; P = 0.09). CONCLUSION: Total fat was associated with complicated disease phenotype and visceral obesity, with higher risk of abdominal surgery and shorter time until surgery.

BACKGROUND: Eating-related distress (ERD) is one type of psychosocial distress among advanced cancer patients and family caregivers. Its alleviation is a key issue in palliative care; however, there is no validated tool for measuring ERD. METHODS: The purpose of this study was to validate tools for evaluating ERD among patients and family caregivers. The study consisted of a development and validation/retest phase. In the development phase, we made preliminary questionnaires for patients and family caregivers. After face validity and content validity, we performed an exploratory factor analysis and discussed the final adoption of items. In the validation/retest phase, we examined factor validity with an exploratory factor analysis. We calculated Pearson's correlation coefficients between the questionnaire for patients, the Functional Assessment of Anorexia/Cachexia Therapy Anorexia Cachexia Subscale (FAACT ACS) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Cachexia 24 (EORTC QLQ-CAX24) and Pearson's correlation coefficients between the questionnaire for family caregivers and the Caregiver Quality of Life Index-Cancer (CQOLC) for concurrent validity. We calculated Cronbach's alpha coefficients (Cronbach's alpha) and intraclass correlation coefficients (ICCs) for internal consistency and test-retest reliability. We performed the Mann-Whitney U test between the questionnaires and cancer cachexia based on criteria from the international consensus for known-group validity. RESULTS: In the development phase, 162 pairs of patients and family caregivers were asked to participate, and 144 patients and 106 family caregivers responded. In the validation/retest phase, 333 pairs of patients and family caregivers were asked to participate, and 234 patients and 152 family caregivers responded. Overall, 183 patients and 112 family caregivers did the retest. Seven conceptual groups were extracted for the ERD among patients and family caregivers, respectively. Patient factors 1-7 correlated with FAACT ACS (r = -0.63, -0.43, -0.55, -0.40, -0.38, -0.54, -0.38, respectively) and EORTC QLQ-CAX24 (r = 0.58, 0.40, 0.60, 0.49, 0.38, 0.59, 0.42, respectively). Family factors 1-7 correlated with CQOLC (r = -0.34, -0.30, -0.37, -0.37, -0.46, -0.42, -0.40, respectively). The values of Cronbach's alpha and ICC of each factor and all factors of patients ranged from 0.84 to 0.96 and 0.67 to 0.83, respectively. Those of each factor and all factors of family caregivers ranged from 0.84 to 0.96 and 0.63 to 0.84, respectively. The cachexia group of patients had significantly higher scores than the non-cachexia group for each factor and all factors. CONCLUSIONS: Newly developed tools for measuring ERD experienced by advanced cancer patients and family caregivers have been validated.

Background: Cardiac rehabilitation (CR) modeled care is recommended for patients with breast cancer to mitigate risk of cardiotoxicity. However, the cardiovascular impact of CR-modeled interventions has not been studied. Objectives: The purpose of this study was to evaluate if a multidisciplinary model of CR reduces cardiotoxicity and improves cardiovascular risk in patients undergoing breast cancer treatment. Methods: We randomly assigned patients with stage I to III breast cancer scheduled to receive anthracycline and/or trastuzumab-based chemotherapy to the CR intervention (n = 37) or usual care (n = 37). The intervention included guideline-directed management of cardiovascular risk factors, dietary counselling, and supervised exercise for 52 weeks. Cardiac magnetic resonance imaging, cardiopulmonary exercise testing, dual-energy x-ray absorptiometry, and serum biomarkers were acquired at baseline and 52 weeks. Results: There was no difference in the primary outcome, left ventricular ejection fraction (LVEF), between groups at 52 weeks (61% ± 6%). Other markers of cardiotoxicity, including high-sensitivity troponin I and brain natriuretic peptide, were similar between groups. However, total cholesterol (5.2 ± 0.8 mmol/L to 4.7 ± 0.8 mmol/L, P = 0.002) and low-density lipoprotein (3.0 ± 0.7 mmol/L to 2.4 ± 0.7 mmol/L, P < 0.001) decreased in the intervention group at 52 weeks and were unchanged in usual care. In all patients, adverse cardiac and metabolic changes occurred over 52 weeks including reductions in LVEF, left ventricular mass, high-density lipoprotein, lean body mass, insulin-like growth factor-1, as well as increased triglycerides, whole-body and truncal fat mass (all P < 0.050). Conclusions: The CR-modeled intervention had no effect on LVEF or biomarkers of cardiotoxicity. Future lifestyle intervention trials in patients with breast cancer should consider targeting other risk factors associated with incident cardiovascular disease.

ABSTRACT
Patients with cancer cachexia frequently suffer from physical symptoms and psychological symptoms of illness, which can lead to emotional distress in patients and family caregivers. Although there is no standard care to manage cancer cachexia despite its high prevalence and negative impact on quality of life in patients and family caregivers, there is accumulating evidence showing the importance of holistic multimodal care for cancer cachexia. However, there is no agreement on the essential components of holistic multimodal care. Therefore, the aims of this review are to give an overview of what is known about the holistic multimodal care and to suggest the composition of a multidisciplinary team to achieve holistic interventions. Holistic multimodal care for cancer cachexia is defined as an approach that addresses physical health through medical, pharmacological, nutritional, and rehabilitative interventions as well as psychological, emotional, and social well-being issues according to the needs of patients and family caregivers. Moreover, an ideal multidisciplinary team is proposed to achieve holistic interventions based on patient- and family-centered care. However, the development of educational programs on cancer cachexia for both clinicians and patients and family caregivers is needed. Furthermore, measurements to assess the benefits of holistic multimodal care also need to be established.
ABSTRACT
Patients with foregut tumors are at high risk of malnutrition. Nutrition care focuses on identifying individuals at risk of malnutrition and optimizing nutrient intake to promote the maintenance of body weight and lean body mass. This multi-center prospective, longitudinal study audited nutrition care practices related to screening for risk of malnutrition (Patient-Generated Subjective Global Assessment Short Form; PG-SGA SF), and nutrition interventions prescribed (route; adequacy of energy and protein intakes). Audits occurred at four time periods: baseline (before treatment) and at 2, 4, and 6 months after starting cancer treatment; 170 patients (esophageal (ESO; n = 51); head and neck (HN; n = 119)) were enrolled. Nutrition risk (PG-SGA SF score ≥ 4) was prevalent at every time period: HN (baseline: 60%; 6 months 66%) and ESO (77%; 72%). Both groups had significant (p < 0.001) weight losses over the 6 month audit period (HN = 13.2% ESO = 11.4%). Enteral nutrition (EN) was most likely to be prescribed at 2 months for HN and at 4 and 6 months for ESO. Target prescribed energy and protein intakes were not met with any nutrition intervention; although adequacy was highest for those receiving EN. Nutrition care practices differed for HN and ESO cancers and there may be time points when additional nutrition support is needed.

BACKGROUND: Cancer cachexia negatively impacts patient outcomes, quality of life and survival. Identification and management of cancer cachexia remains challenging to healthcare professionals (HCPs). The aim of this assessment was to identify current gaps in HCPs' knowledge and practice for identifying and managing adults with cancer-related cachexia. Results may guide development of new educational programmes to close identified gaps and improve outcomes of cancer patients. METHODS: An international assessment was conducted using a mixed-methods approach including focus group interviews with subject matter experts and an electronic survey of practising HCP. The assessment was led by the Society on Sarcopenia, Cachexia and Wasting Disorders (SCWD) and was supported by in-country collaborating organizations. RESULTS: A quantitative survey of 58 multiple-choice questions was completed by physicians, nurses dietitians and other oncology HCP (N = 2375). Of all respondents, 23.7% lacked confidence in their ability to provide care for patients with cancer cachexia. Patients with gastrointestinal, head and neck, pulmonary cancers and leukaemia/lymphoma were reported as those at highest risk for cachexia. Only 29.1% of respondents recognized a key criterion of cancer cachexia as >5% weight loss from baseline, but many (14.4%) did not utilize a standardized definition of cancer cachexia. Despite this, most clinicians (>84%) were able to identify causes of weight loss-reduced oral intake, progressive disease, side effects of therapy and disease-related inflammation. Of all respondents, 52.7% indicated newly diagnosed patients with cancer should be screened for weight loss. In practice, 61.9% reported that patient weight was systematically tracked over time, but only 1125 (47.4%) reported they weigh their cancer patients at each visit. Treatment of cachexia focused on increasing the patient's nutritional intake by oral nutritional supplements (64.2%), energy and protein fortified foods (60.3%) and counselling by a dietitian (57.1%). Whereas many respondents (37.3%) considered cachexia inevitable, most (79.2%) believed that an interprofessional team approach could improve care and that use of standardized tools is critical. CONCLUSIONS: Findings from this international assessment highlight the challenges associated with the care of patients with cancer cachexia, opportunities for interventions to improve patient outcomes and areas of variance in care that would benefit from further analysis.

In 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) studies, maximum standardized uptake value (SUVmax) is the parameter commonly used to provide a measurement of the metabolic activity of a tumor. SUV normalized by body mass is affected by the proportions of body fat and lean tissue, which present high variability in patients with cancer. SUV corrected by lean body mass (LBM), denoted as SUL, is recommended to provide more accurate, consistent, and reproducible SUV results; however, LBM is frequently estimated rather than measured. Given the increasing importance of a quantitative PET parameter, especially when comparing PET studies over time to evaluate disease response clinically, and its use in oncological clinical trials, we set out to evaluate the commonly used equations originally derived by James (1976) and Janmahasatian et al. (2005) against computerized tomography (CT)-derived measures of LBM. Methods: Whole-body 18F-FDG PET images of 195 adult patients with cancer were analyzed retrospectively. Representative liver SUVmean was normalized by total body mass. SUL was calculated using a quantitative determination of LBM based on the CT component of the PET/CT study (LBMCT) and compared against the equation-estimated SUL. Bland and Altman plots were generated for SUV-SUL differences. Results: This consecutive sample of patients undergoing usual care (men, n = 96; women, n = 99) varied in body mass (38-127 kg) and in Body Mass Index (BMI) (14.7-47.2 kg/m2). LBMCT weakly correlated with body mass (men, r2 = 0.32; women, r2 = 0.22), and thus SUV and SULCT were also weakly correlated (men, r2 = 0.24; women, r2 = 0.11). Equations proved inadequate for the assessment of LBM. LBM estimated by James' equation showed a mean bias (overestimation of LBM compared with LBMCT) in men (+6.13 kg; 95% CI 4.61-7.65) and in women (+6.32 kg; 95% CI 5.26-7.39). Janmahasatian's equation provided similarly poor performance. Conclusions: CT-based LBM determinations incorporate the patient's current body composition at the time of a PET/CT study, and the information garnered can provide care teams with information with which to more accurately determine FDG uptake values, allowing comparability over multiple scans and treatment courses and will provide a robust basis for the use of PET Response Criteria in Solid Tumors (PERCIST) in clinical trials.
