Factors associated with multimodal care practices for cancer cachexia among registered dietitians.

This study aimed to determine factors associated with multimodal care practices for cancer cachexia among registered dietitians (RDs) working in cancer care. A secondary analysis was performed using RDs' data. Data on knowledge, skills, and confidence in multimodal care were obtained. Nine items regarding multimodal care practices were evaluated. Subjects were divided into two groups based on their answers associated with the nine items. Comparisons were obtained using the Mann-Whitney U test or chi-squared test. Multiple regression analysis was performed to identify the critical factors involved in practicing multimodal care by determining the variables with significant differences between the two groups. Two hundred thirty-two RDs were included in this study. Significant differences were observed in their primary area of practice (p = 0.023), the number of clinical guidelines used (p < 0.001), the number of items used in cancer cachexia assessment (p = 0.002), the number of symptoms used in cancer cachexia assessment (p = 0.039), training for cancer cachexia (p < 0.001), knowledge of cancer cachexia (p < 0.001), and confidence in cancer cachexia management (p < 0.001). The number of symptoms used in cancer cachexia assessment (B = 0.42, p = 0.019), knowledge of cancer cachexia (B = 6.60, p < 0.001), and confidence in cancer cachexia management (B = 4.31, p = 0.010) were identified as critical factors according to the multiple regression analysis. The RDs' knowledge and confidence in cancer cachexia management were associated with their multimodal care practices.

Progressive, multi-organ, and multi-layered nature of cancer cachexia.

Cancer cachexia is a complex, multifaceted condition that negatively impacts the health, treatment efficacy, and economic status of cancer patients. The management of cancer cachexia is an essential clinical need. Cancer cachexia is currently defined mainly according to the severity of weight loss and sarcopenia (i.e., macrosymptoms). However, such macrosymptoms may be insufficient to give clinicians clues on how to manage this condition as these symptoms appear at the late stage of cancer. We need to understand earlier events during the progression of cancer cachexia so as not to miss a clinical opportunity to control this complex syndrome. Recent research indicates that cancer-induced changes in the host are much wider than previously recognized, including disruption of liver function and the immune system. Furthermore, such changes are observed before the occurrence of visible distant metastases (i.e., in early, localized cancers). In light of these findings, we propose to expand the definition of cancer cachexia to include all cancer-induced changes to host physiology, including changes caused by early, localized cancers. This new definition of cancer cachexia can provide a new perspective on this topic, which can stimulate the research and development of novel cancer cachexia therapies.

Factors Associated With Practice of Multimodal Care for Cancer Cachexia Among Physicians and Nurses Engaging in Cancer Care.

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. 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. 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. Specialization in palliative care, specific knowledge, and confidence were associated with the practice of multimodal care for cancer cachexia.

Perspectives of registered dietitians and factors associated with their personal accomplishment in the management of cancer cachexia.

Registered dietitians (RDs) have the potential in cancer cachexia management. We investigated RDs' knowledge on cancer cachexia and assessed the effects of factors on RDs' perception of playing an important role in cancer cachexia management. This is a secondary analysis of a survey examining the perspectives of health care professionals on cancer cachexia management. We sent the questionnaire to 451 RDs. RDs were divided into two groups: RDs with and without the perception. Comparisons were made using the Mann-Whitney U test or chi-square test. To examine the effects of factors on the perception, estimated crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the logistic regression model were calculated. A total of 237 RDs were analyzed. Significant differences were observed in the number of cancer patients/month, the primary area of practice, the number of clinical guidelines used, the number of items used, the number of symptoms used, and training for cancer cachexia management (p values all < 0.05). After adjustments, the factors of cancer care experience ≥ 20years (OR 8.32, 95% CI 1.22-56.70; p = 0.030), the number of patients/month ≥ 50 (OR 27.35, 95% CI 3.99-187.24; p = 0.001), using the clinical guidelines (OR 2.69, 95% CI 1.29-5.61; p = 0.008), the number of items ≥ 5 (OR 3.52, 95% CI 1.47-8.40; p = 0.005), and receiving training (OR 3.91, 95% CI 1.77-8.67; p = 0.001) significantly associated with the perception. Specific knowledge and training as well as abundant experience were associated with the perception.

Perspectives of Health Care Professionals on Multimodal Interventions for Cancer Cachexia.

Holistic multimodal interventions have not been established for cancer cachexia. The beliefs and perceptions of health care professionals (HCPs) based on their experiences influence the interventions. HCPs' knowledge, perceptions, and practices in cancer cachexia management were evaluated. A nationwide questionnaire survey was conducted that focused on the perspectives of HCPs on interventions in 451 designated cancer hospitals across Japan. Descriptive statistics were applied. Among 2255 participants, 1320 responded (58.5%), and 1188 in 258 institutes were included in the analysis. The current international definition of cancer cachexia is not commonly known and recent clinical practice guidelines have not been widely adopted. More than 50% of participants considered ≥5% weight loss in six months and ECOG PS (Eastern Cooperative Oncology Group Performance Status) 2-4 to be cancer cachexia, whereas 50% answered that there was no relationship between life expectancy and cancer cachexia. Participants tended to consider it important to initiate nutritional and exercise interventions before cancer cachexia becomes apparent. The majority of participants recognized the importance of holistic multimodal interventions, particularly for the management of physical and psychological symptoms; however, only 20% reported that they educated patients and families. Furthermore, 33% of participants considered themselves to have provided patients and families with sufficient nutritional and exercise interventions and evidence-based information. The results reveal that HCPs are not regularly providing education and emotional support to patients and families suffering from cancer cachexia. The results also show the need for education for HCPs to enhance implementation of holistic multimodal interventions for cancer cachexia.

Investigation into the role of anti-diabetic agents in cachexia associated with metastatic cancer

Cancer cachexia (CC) is a syndrome associated with cancer, and the global burden is increasing rapidly. Alteration in carbohydrate, lipid and protein metabolism along with systemic inflammation are characteristics of CC. Until now the available treatment for CC is limited to controlling inflammation and nutrition. Anti-diabetics are widely used agents to treat diabetics, this agent's act by regulating the carbohydrate metabolism, also they are known to have beneficial effects in maintaining protein and lipid balance. Role of anti-diabetics in cancer is being evaluated continuously and biguanides, dipeptidyl peptidase 4 (DPP4) inhibitors and Sodium glucose co-transporter 2 (SGLT2) inhibitors have proven anti-cancer potential. In this study, metastatic B16-F1 cell line induced cancer cachexia model used to evaluate potential of biguanides (metformin), DPP-4 inhibitors (teneligliptin and vildagliptin) and SGLT2 inhibitors (empagliflozin and dapagliflozin) in cancer cachexia. Our results suggest that anti-diabetic agents have potential to decrease rate of proliferation of tumor, restrict body mass markers, decrease inflammation, regulate carbohydrate mechanism and induce skeletal muscle hypertrophy. These findings may be helpful in management of cancer cachexia and increase the quality of life and survival chances of cancer cachexia patient.

The role of microRNA in cancer cachexia and muscle wasting: A review article.

Almost half of cancer patients experience cachexia syndrome. Cachexic patients are at risk of increased side effects of chemotherapy, reduced tolerance to chemotherapy drugs, longer duration of treatment period, and decreased quality of life. Cancer cachexia is a multifactorial syndrome. Micro ribonucleic acid (miRNA), a “non-coding RNA”, is considered to be a risk factor of cachexia and muscle wasting in cancer patients. miRNA has a role in affecting protein regulation, associated with different inflammatory and disease pathways. miRNA can also affect cytokines or directly change the regulation of metabolism that lead to cachexia. In this review, we want to focus on the pathophysiology to give a better understanding about the role of miRNA in the development of cancer cachexia. Based on various pathways of miRNA in cancer cachexia, it can be a potential target for therapeutic strategies. Improved knowledge about miRNA can give the opportunity to develop new treatment in the management of cancer cachexia.

Management of Cancer Cachexia: Attempting to Develop New Pharmacological Agents for New Effective Therapeutic Options.

Cancer cachexia (CC) is a multifactorial syndrome characterized by systemic inflammation, uncontrolled weight loss and dramatic metabolic alterations. This includes myofibrillar protein breakdown, increased lipolysis, insulin resistance, elevated energy expediture, and reduced food intake, hence impairing the patient's response to anti-cancer therapies and quality of life. While a decade ago the syndrome was considered incurable, over the most recent years much efforts have been put into the study of such disease, leading to the development of potential therapeutic strategies. Several important improvements have been reached in the management of CC from both the diagnostic-prognostic and the pharmacological viewpoint. However, given the heterogeneity of the disease, it is impossible to rely only on single variables to properly treat patients presenting this metabolic syndrome. Moreover, the cachexia symptoms are strictly dependent on the type of tumor, stage and the specific patient's response to cancer therapy. Thus, the attempt to translate experimentally effective therapies into the clinical practice results in a great challenge. For this reason, it is of crucial importance to further improve our understanding on the interplay of molecular mechanisms implicated in the onset and progression of CC, giving the opportunity to develop new effective, safe pharmacological treatments. In this review we outline the recent knowledge regarding cachexia mediators and pathways involved in skeletal muscle (SM) and adipose tissue (AT) loss, mainly from the experimental cachexia standpoint, then retracing the unimodal treatment options that have been developed to the present day.

Cancer cachexia: a multifactoral disease that needs a multimodal approach

Cancer cachexia is a complex condition that occurs in approximately 50% of cancer patients and in 80% of those with advanced cancer. It is characterized by lean body mass loss, adipose tissue loss, altered metabolism, increased inflammation, and a decrease in quality of life. Cancer cachexia is a frustrating condition to manage and treatment requires an innovative approach. The purpose of this article is to review the current treatments for cancer cachexia and how they could be used in a multimodal approach. Cancer cachexia has many causes, but is primarily a result of reduced energy-protein intake and altered metabolism augmented by a proinflammatory state. There is not a formal consensus on diagnosing cancer cachexia, but proactive screening and assessments for malnutrition are an effective first step toward identifying high-risk patients. Treatment of cancer cachexia includes optimizing nutrition care, using appropriate pharmacological agents, preserving lean body mass, and the cooperation of the healthcare team. Cancer cachexia is a complex multifactorial condition that can only be successfully managed and treated with a multimodal approach that involves a multidisciplinary team that includes an oncology registered dietitian nutritionist and exercise physiologist that target early detection and management of cancer cachexia.

Defining a new model of interdisciplinary cancer cachexia care in regional Victoria, Australia.

Cachexia is a wasting condition affecting approximately 50% of cancer patients, associated with decreased quality of life and survival. Barwon Health's Cachexia and Nutrition Support Service provides person-centred interdisciplinary care to assist the management of cachexia symptoms. This study describes a novel and effective service model established in a regional cachexia clinic and the patient population it serves. A descriptive, retrospective longitudinal study was conducted of records from patients attending Barwon Health between 2008 and 2013 (n = 175), alongside the description of service refinement over this time. Patients with ≥ 2 attendance dates were assessed for anthropometric measures, follow-up intervals, and muscle function outcomes to describe patient trajectory during clinic involvement. This is the first detailed description of a successful interdisciplinary clinic specific to cancer cachexia management, where patients are seen outside established 8- to 12-week structured programs which prevail in other cachexia clinics. Seventy-five patients (43%) attended one appointment only, with almost half of these (n = 33) first attending within 60days of death. Of the 99 patients with two or more appointments, 49% displayed positive outcomes with > 2-kg weight gain between two consecutive appointments, and > 50% improved functional strength between two consecutive appointments. The majority of patients attending clinic multiple times maintained or increased weight and functional status during their involvement with the service. However, successes of care provision were muted by high attrition, primarily due to delayed referral and expected high mortality within the study cohort. Planned future analyses with greater patient numbers and cancer stratification will establish cachectic populations most likely to benefit from this novel mode of interdisciplinary care. The Cachexia and Nutrition Support Service provides an effective and efficient service model for the provision of specialist cachexia care to community-dwelling patients in regional Australia.

Nutritional status and interventions in hospice: physician assessment of cancer patients.

Cancer cachexia is a multifactorial syndrome characterised by a progressive loss of skeletal muscle mass. It adversely influences quality of life, treatment response and survival. Early identification and multimodal interventions can potentially treat cancer cachexia. However, healthcare professionals demonstrate a lack of understanding and the ability to identify cancer cachexia early. The present study aimed to evaluate the assessment by physicians of nutritional status in cancer patients admitted to hospice. A retrospective medical record review was conducted on all cancer admissions to a specialist in-patient palliative care unit over a 4-month period between October 2016 and January 2017. Charts were reviewed for evidence of documented nutritional assessment by physicians. Data were collected from the referral letter, admission notes, drug kardex and discharge letter. The information extracted included: (i) patient demographics and characteristics; (ii) terms used by physicians to describe nutritional status; (iii) any record of nutritional impact symptoms (NIS) experienced by the patient; and (iv) nutritional interventions prescribed. One hundred and forty admissions were evaluated. Nutritional terminology and NIS were most commonly documented on the admission notes. Only 41% of documents recorded any nutritional term used by physicians to assess nutritional status. Furthermore, 71% of documents recorded at least one NIS experienced by the patient. Fatigue was the most frequent NIS. We identified an inadequate nutritional assessment of cancer patients admitted to hospice. Implementation of a nutritional symptom checklist and nutrition screening tools, along with enhanced physician education and multidisciplinary nutrition care, could improve the identification and management of cancer cachexia in the palliative care setting.

Comparison of three different treatment modalities in the management of cancer cachexia.

The optimal treatment of cancer cachexia remains unknown. In this study, we compared the efficacy of three different treatment modalities in the management of cancer cachexia. Sixty-two assessable cachectic cancer patients were randomized to one of the following three arms: 1) megesterol acetate (MA) plus meloxicam (n = 23); 2) MA plus meloxicam plus oral eicosapentaenoic acid (EPA)-enriched nutritional supplement (n = 21); or 3) meloxicam plus oral EPA-enriched nutritional supplement (n = 18). Treatment duration was 3 months. The treatment arms were well balanced at baseline. The primary efficacy (body weight and lean body mass) and secondary efficacy (body mass index, quality of life, and serum levels of IL-6 and TNF-α) parameters improved after treatment in all three arms. There were no statistically significant differences between treatment groups in the mean percentage changes in all efficacy parameters from baseline to end of study. MA plus meloxicam or EPA supplement plus meloxicam may be effective treatment options in the management of cancer cachexia. The combined use of these agents does not provide further advantages.

Epigenetic targeting of bromodomain protein BRD4 counteracts cancer cachexia and prolongs survival

Cancer cachexia is a devastating metabolic syndrome characterized by systemic inflammation and massive muscle and adipose tissue wasting. Although it is responsible for approximately one-third of cancer deaths, no effective therapies are available and the underlying mechanisms have not been fully elucidated. We previously identified the bromodomain and extra-terminal domain (BET) protein BRD4 as an epigenetic regulator of muscle mass. Here we show that the pan-BET inhibitor (+)-JQ1 protects tumor-bearing mice from body weight loss and muscle and adipose tissue wasting. Remarkably, in C26-tumor-bearing mice (+)-JQ1 administration dramatically prolongs survival, without directly affecting tumor growth. By ChIP-seq and ChIP analyses, we unveil that BET proteins directly promote the muscle atrophy program during cachexia. In addition, BET proteins are required to coordinate an IL6-dependent AMPK nuclear signaling pathway converging on FoxO3 transcription factor. Overall, these findings indicate that BET proteins may represent a promising therapeutic target in the management of cancer cachexia.

Management of Cancer Cachexia and Guidelines Implementation in a Comprehensive Cancer Center: A Physician-Led Cancer Nutrition Program Adapted to the Practices of a Country

ContextCancer-associated cachexia is correlated with survival, side-effects, and alteration of the patients' well-being. ObjectivesWe implemented an institution-wide multidisciplinary supportive care team, a Cancer Nutrition Program (CNP), to screen and manage cachexia in accordance with the guidelines and evaluated the impact of this new organization on nutritional care and funding. MethodsWe estimated the workload associated with nutrition assessment and cachexia-related interventions and audited our clinical practice. We then planned, implemented, and evaluated the CNP, focusing on cachexia. ResultsThe audit showed a 70% prevalence of unscreened cachexia. Parenteral nutrition was prescribed to patients who did not meet the guideline criteria in 65% cases. From January 2009 to December 2011, the CNP team screened 3078 inpatients. The screened/total inpatient visits ratio was 87%, 80%, and 77% in 2009, 2010, and 2011, respectively. Cachexia was reported in 74.5% (n = 2253) patients, of which 94.4% (n = 1891) required dietary counseling. Over three years, the number of patients with artificial nutrition significantly decreased by 57.3% (P < 0.001), and the qualitative inpatients enteral/parenteral ratio significantly increased: 0.41 in 2009, 0.74 in 2010, and 1.52 in 2011. Between 2009 and 2011, the CNP costs decreased significantly for inpatients nutritional care from 528,895€ to 242,272€, thus financing the nutritional team (182,520€ per year). ConclusionOur results highlight the great benefits of implementing nutritional guidelines through a physician-led multidisciplinary team in charge of nutritional care in a comprehensive cancer center.

Pharmacological management update: clinical significance of anamorelin clinical trials for the treatment of cancer cachexia in advanced cancer patients

Cancer cachexia is a debilitating and multifactorial metabolic condition that is highly prevalent among advanced cancer patients. Currently there are limited effective pharmacological treatment options for the management of cancer cachexia. In recent years, there is an increasing attention on the use of ghrelin-receptor agonists in the treatment of cancer cachexia. In this perspective, we discuss recent clinical trials that have evaluated the efficacy and safety of ghrelin-receptor agonist, anamorelin for the treatment of anorexia cancer cachexia syndrome and its potential role of anamorelin in clinical care in advanced cancer patients.

An Epidemiological Survey of Cachexia in Advanced Cancer Patients and Analysis on Its Diagnostic and Treatment Status

Recently, an international consensus diagnostic criterion for cancer cachexia was proposed. The aim of the study is to assess the prevalence of cachexia in patients with advanced cancer and to assess the current status of the diagnosis and management of cancer cachexia. A total of 390 patients with advanced cancer were included. There were 140 patients with cachexia and the prevalence was 35.9%. The prevalence was highest in pancreatic cancer (88.9%), followed by gastric cancer (76.5%) and esophageal cancer (52.9%). Sixty-three patients with cancer cachexia have CT scans available for muscle mass evaluation and 98.4% were sarcopenic. Cachectic patients have a significantly lower overall quality of life and a higher symptom burden. According to oncology physicians, only 33 patients were considered to have cancer cachexia. The false negative rate amounted to 76.4%. The positive rate was related to the body mass index and Eastern Cooperative Oncology Group performance status of the patients. There were few types of pharmacological approaches for cancer cachexia and more than half of cachectic patients did not receive any anticachexia treatment. These results indicate that the prevalence of cachexia in advanced cancer patients was high. However, cancer cachexia was rarely recognized and clinical management for cancer cachexia was very inadequate.

All Bones and No Meat: Advances in the Management of Cancer Cachexia (SA535)

•Discuss the mechanisms of anorexia and cachexia.•Discuss the evolving definitions of anorexia and cachexia and the assessment tools available for clinical practice and research.•Summarize evidence-based treatment strategies, with particular emphasis on novel therapeutics. The cachexia-anorexia syndrome (CAS) is a multifactorial syndrome characterized by involuntary loss of skeletal muscle and fat, decreased quality of life, and shortened survival. Although typically associated with cancer, CAS is also common in many chronic illnesses, such as heart failure, chronic obstructive pulmonary disease, human immunodeficiency virus infection, and renal and hepatic failure. Over the past few years, significant progress has been made toward our understanding of the pathogenesis of this syndrome, resulting in the development of novel therapeutics. Anorexia can be classified as (a) primary anorexia, which is mediated by inflammatory cytokines, such as tumor necrosis factor, interleukin 1, and interleukin, 6 and various anorexigenic factors, such as leptin, cholecystokinin, and peptide YY; and (b) secondary anorexia related to various comorbidities, such as mucositis, early satiety, nausea, taste alteration, and dysphagia. In addition to central effects on the hypothalamus causing loss of appetite, CAS is also a peripheral phenomenon characterized by wasting of muscle and fat due to an imbalance between the catabolic mediators (e.g., cortisol, glucagon, adrenalin, cytokines) and anabolic mediators (e.g., growth hormone, insulin, testosterone). Given the high prevalence of CAS, it is important to routinely assess common nutritional impact symptoms and to monitor body composition. Although megestrol acetate and corticosteroids have some activity against anorexia, they have significant side effects and limited effect on lean body mass. Emerging therapies for CAS include selective androgen receptor modulators, ghrelin analogues, and cytokine inhibitors that show preliminary evidence for improving appetite, lean body mass, function, and quality of life. In this session, we aim to 1) provide a better understanding of the pathophysiology for anorexia and cachexia, 2) review the latest consensus definition and assessment tools, and 3) discuss up-to-date therapeutic strategies in managing this devastating syndrome. The last 10 minutes will be available for questions and discussions.

A systematic and interdisciplinary approach to the measurement of outcomes over the disease trajectory in a unique specialized cachexia clinic.

25 Background: Cancer cachexia affects 60-80% of advanced cancer patients and leads to weight loss, worsening functional status, and increased mortality. Thus, specialized clinics are needed to measure nutritional and functional trajectories over time in this population. Recently, the McGill University Health Centre has developed a systematic, standardized and interdisciplinary approach for the profiling and management of cancer cachexia. Methods: Patients with advanced cancer were recruited and categorized as cachetic. The following information was collected at baseline and at three follow-up visits: hand grip strength measured by Jamar dynamometer, the Edmonton Symptom Assessment System (ESAS) and the abridged Patient Generated Subjective Global Assessment (aPG-SGA) questionnaires. Results: Fifty-nine patients were eligible for this study yet only 24 completed 3 follow-ups and were included. There were 15 men and 9 women, mean age 65.7 years. Five patients had locally advanced disease and 19 had metastatic disease. The table contains results for handgrip strength, ESAS and aPG-SGA scores. Conclusions: Following baseline assessment and treatment, patients were noted to have a significant improvement in the aPG-SGA total score. Handgrip strength was maintained throughout the follow up period. ESAS appetite and fatigue exhibited a positive trend but did not achieve significance over time. This work suggests the benefits of an interdisciplinary cachexia clinic for the maintenance of nutritional and functional status in patients with cancer cachexia as well as possible improvements in quality of life.
