iCare - a self-directed, interactive online program to improve health and wellbeing for people living with upper gastrointestinal or hepato-pancreato-biliary cancers, and their informal carers: the study protocol for a Phase II randomised controlled trial.

BACKGROUND: Up to 70% of people diagnosed with upper gastrointestinal (GI) tract or hepato-pancreato-biliary (HPB) cancers experience substantial reductions in quality of life (QoL), including high distress levels, pain, fatigue, sleep disturbances, weight loss and difficulty swallowing. With few advocacy groups and support systems for adults with upper GI or HPB cancers (i.e. pancreas, liver, stomach, bile duct and oesophageal) and their carers, online supportive care programs may represent an alternate cost-effective mechanism to support this patient group and carers. iCare is a self-directed, interactive, online program that provides information, resources, and psychological packages to patients and their carers from the treatment phase of their condition. The inception and development of iCare has been driven by consumers, advocacy groups, government and health professionals. The aims of this study are to determine the feasibility and acceptability of iCare, examine preliminary efficacy on health-related QoL and carer burden at 3- and 6-months post enrolment, and the potential cost-effectiveness of iCare, from health and societal perspectives, for both patients and carers. METHODS AND ANALYSIS: A Phase II randomised controlled trial. Overall, 162 people with newly diagnosed upper GI or HPB cancers and 162 carers will be recruited via the Upper GI Cancer Registry, online advertisements, or hospital clinics. Patients and carers will be randomly allocated (1:1) to the iCare program or usual care. Participant assessments will be at enrolment, 3- and 6-months later. The primary outcomes are i) feasibility, measured by eligibility, recruitment, response and attrition rates, and ii) acceptability, measured by engagement with iCare (frequency of logins, time spent using iCare, and use of features over the intervention period). Secondary outcomes are patient changes in QoL and unmet needs, and carer burden, unmet needs and QoL. Linear mixed models will be fitted to obtain preliminary estimates of efficacy and variability for secondary outcomes. The economic analysis will include a cost-consequences analysis where all outcomes will be compared with costs. DISCUSSION: iCare provides a potential model of supportive care to improve QoL, unmet needs and burden of disease among people living with upper GI or HPB cancers and their carers.

Enhancing the provision of cancer nutrition information to support care through experience-based co-design: a mixed-methods study.

PURPOSE: Nutrition is essential within cancer care, yet patient and carer access to nutrition care and information is variable. This study aimed to (1) investigate patient and carer access and perceptions, and health professional views and practices, relating to cancer nutrition information and care; and (2) co-design interactive resources to support optimal nutrition care. METHODS: Patients and carers completed a survey regarding access to nutrition care and information. Seven multidisciplinary health service teams were invited to participate in a survey and focus group to assess barriers and enablers in nutrition practices. Focus groups were recorded, transcribed and thematically analyzed. Eligible patients, carers, and health professionals were invited to four virtual workshops utilizing experience-based co-design methods to identify nutrition priority areas and design resources. Workshop participant acceptability of the resources was measured. RESULTS: Of 104 consumer survey respondents (n = 97 patients, n = 7 carers), 61% agreed that it "took too much time to find evidence-based nutrition and cancer information", and 46% had seen a dietitian. Thirty-four of 38 health professionals completed the survey and 30 participated in a focus group, and it was identified the greatest barriers to delivering nutrition care were lack of referral services, knowledge or skill gaps, and time. Twenty participants (n = 10 patients and carers, n = 10 health professionals) attended four workshops and co-designed a suite of 46 novel resources rated as highly acceptable. CONCLUSION: Improved communication, training, and availability of suitable resources could improve access to and support cancer nutrition information and care. New, co-designed cancer nutrition resources were created and deemed highly acceptable to patients, carers, and health professionals.

Co-design of a cancer nutrition care pathway by patients, carers, and health professionals: the CanEAT pathway.

PURPOSE: Limited practical resources exist to guide optimal nutrition care for patients, carers, and health professionals (HPs). This study aimed to co-design a cancer nutrition care pathway to guide and improve the provision of consistent, evidence-based care with consumers and HPs. METHODS: This study utilised an experienced-based co-design (EBCD) approach over five stages. Stage 1 involved stakeholder engagement and a literature review. Stage 2 included a survey and focus groups with patients/carers. Co-design workshops were conducted within stage 3, key stakeholder consultation within stage 4, and the finalisation and dissemination of the cancer nutrition care pathway formed stage 5. Results of stages 3 to 5 are the focus of this paper. RESULTS: Two co-design workshops were held with patients, carers, and HPs (n = 32 workshop 1; n = 32 workshop 2), who collectively agreed on areas of focus and key priorities. Following this, a consultation period was completed with patients, carers, and HPs (n = 45) to refine the pathway. The collective outcome of all study stages was the co-design of a cancer nutrition care pathway (the CanEAT pathway) defining optimal cancer nutrition care that combines evidence-based practice tips into a centralised suite of resources, tools, and clinical guidance. CONCLUSION: The CanEAT pathway was co-designed by patients, carers, and HPs. The EBCD approach is a meaningful way to develop targeted improvements in cancer care. The CanEAT pathway is freely available to guide and support patients, carers, and HPs to aid the implementation of optimal nutrition care into clinical practice.

Health service nutrition practices and associations with clinical outcomes in patients undergoing resection for upper gastrointestinal cancer: Results from the multi-centre NOURISH point prevalence study.

BACKGROUND: The present study aimed to investigate health service nutrition practices of sites providing care to patients undergoing surgery for upper gastrointestinal cancer within Australia, including the provision of perioperative nutrition support services and outpatient clinics, as well as the use of evidence-based nutrition care pathways/protocols. Secondary aims were to investigate associations between the use of a nutrition care pathway/protocol and patient outcomes. METHODS: Principal investigator dietitians for the sites (n = 27) participating in the NOURISH point prevalence study participated in a purpose-built site-specific survey regarding perioperative nutrition practices and protocols. Data from the 200 patients who participated in the study (including malnutrition prevalence, preoperative weight loss and receipt of dietetics intervention, intraoperative feeding tube insertions, provision of nutrition support day 1 post surgery, length of stay, and complications) were investigated using multivariate analysis to determine associations with the sites' use of a nutrition care pathway/protocol. RESULTS: The majority of sites (>92%) reported having dietetics services available in chemotherapy/radiotherapy. Eighty-five percent of sites reported having some form of outpatient clinic service; however, a routine service was only available at 26% of sites preoperatively and 37% postoperatively. Most preoperative services were embedded into surgical/oncology clinics (70%); however, this was reported for only 44% of postoperative clinics. Only 44% had a nutrition care pathway/protocol in place. The use of a nutrition care pathway/protocol was associated with lower rates of malnutrition, as well as higher rates of preoperative dietetics intervention, intraoperative feeding tube insertions, and European Society of Clinical Nutrition and Metabolism (ESPEN) guideline compliant care day 1 post surgery. CONCLUSIONS: The results of the present study demonstrate varied perioperative outpatient nutrition services in this high-risk patient group. The use of nutrition care pathways and protocols was associated with improved patient outcomes.

Implementation of a standardised perioperative nutrition care pathway in upper gastrointestinal cancer surgery: A multisite pilot study.

BACKGROUND: Perioperative nutrition support is recommended for patients undergoing upper gastrointestinal (UGI) cancer surgery; however, limited evidence exists regarding implementation of a nutrition care pathway in clinical practice. The aims of this pilot study were to determine whether implementation of a standardised perioperative nutrition pathway for patients undergoing UGI cancer surgery improves access to dietetics care, as well as to evaluate study feasibility, fidelity, resource requirements and effect on clinical outcomes. METHODS: Patients with newly diagnosed UGI cancer from four major metropolitan hospitals in Melbourne, planned for curative intent surgery, were included in the prospective pilot study (n = 35), with historical controls (n = 35) as standard care. Outcomes were dietetics care (dietetics contacts) nutritional status, hand grip strength, weight change, preoperative hospital admissions, complications and length of stay, recruitment feasibility, fidelity and adherence, and resource requirements. Continuous data were analysed using independent samples t test accounting for unequal variances or a Mann-Whitney U test. Dichotomous data were analysed using Fisher's exact test. RESULTS: The percentage of participants receiving preoperative dietetic intervention increased from 55% to 100% (p < 0.001). Mean ± SD dietetics contacts increased from 2.2 ± 3.7 to 5.9 ± 3.9 (p < 0.001). Non-statistically significant decreases in preoperative nutrition-related hospital admissions, and surgical complications were demonstrated in patients who underwent neoadjuvant therapy. Recruitment rate was 81%, and adherence to the nutrition pathway was high (> 70% for all stages of the pathway). The mean ± SD estimated resource requirement for the preoperative period was 3.7 ± 2.8 h per patient. CONCLUSIONS: Implementation of this standardised nutrition pathway resulted in improved access to dietetics care. Recruitment feasibility and high fidelity to the intervention suggest that a larger study would be viable.

Nutrition support use and clinical outcomes in patients with multiple myeloma undergoing autologous stem cell transplant.

PURPOSE: Malnutrition is associated with worse outcomes post-haematopoietic stem cell transplantation, with nutrition support recommended for people who are malnourished or have prolonged inadequate energy intake. We investigated associations between nutritional status, nutrition support type and clinical outcomes in adults with multiple myeloma post stem cell transplantation. METHODS: Medical records (2015-2020) were reviewed to retrieve demographics, anthropometry, dietary data, nutrition support type (enteral/oral versus parenteral), and clinical outcomes (engraftment time, infection, length of stay, weight changes). Relationships were examined using linear regression modelling and Fisher's exact test. RESULTS: One hundred thirteen participants were included (61% male; median age 62 years). Fifteen participants (13%) received parenteral and 98 (87%) received enteral/oral nutrition support. Parenteral nutrition was associated with shorter platelet engraftment time by 2.7 days (p = 0.036) and a longer hospital stay by 6.1 days (p < 0.001). Nutrition support was not associated with neutrophil engraftment time (p = 0.365). Inadequate energy intake for ≥ 7 days was not associated with any clinical outcomes (p > 0.05). CONCLUSIONS: Participants who received parenteral nutrition reached platelet engraftment sooner but were in hospital longer. Inadequate energy intake for ≥ 7 days did not impact clinical outcomes. Multi-site prospective studies are warranted to confirm results.

Implementing a standardised perioperative nutrition care pathway in upper gastrointestinal cancer surgery: a mixed-methods analysis of implementation using the Consolidated Framework for Implementation Research.

BACKGROUND: Implementation studies of complex interventions such as nutrition care pathways are important to health services research, as they support translation of research into practice. There is limited research regarding implementation of a nutrition care pathway in an upper gastrointestinal (UGI) cancer population. The aim of this study was to comprehensively evaluate the implementation process of a perioperative nutrition care pathway in UGI cancer surgery using The Consolidated Framework for Implementation Research (CFIR). METHODS: This was a mixed methods implementation study conducted during a pilot study of a standardised nutrition care pathway across four major hospitals between September 2018 to August 2019. Outcome measures included five focus groups among study dietitians (n = 4-8 per group), and quantitative satisfaction surveys from multi-disciplinary team (MDT) members (n = 14) and patients (n = 18). Focus group responses were analysed thematically using the CFIR constructs, which were used as a priori codes. Survey responses were summarised using means and standard deviations. A convergent parallel mixed methods approach according to CFIR domains and constructs was used to integrate qualitative and quantitative data. RESULTS: Qualitative data demonstrated that dietitian perceptions primarily aligned with five CFIR constructs (networks and communications, structural characteristics, adaptability, compatibility and patient needs/resources), indicating a complex clinical and implementation environment. Challenges to implementation mostly related to adapting the pathway, and the compatibility of nutrition coordination to existing aspects of care within each setting. Identified benefits from dietitian qualitative data and MDT survey responses included increased engagement between the dietitian and MDT, and a more proactive approach to nutrition care. Patients were highly satisfied with the service, with the majority of survey items being rated highly (≥4 of a possible 5 points). CONCLUSIONS: The nutrition care pathway was perceived to be beneficial by key stakeholders. Based on the findings, sustainability and compliance to this model of care may be achieved with improved systems level coordination and communication.

Early postoperative feeding following surgery for upper gastrointestinal cancer: A systematic review.

Nutrition post major upper gastrointestinal (UGI) cancer surgery is a significant consideration known to affect postoperative recovery and the ability to tolerate adjuvant treatment. This systematic review assessed the effect of early oral feeding (EOF), compared to traditional timing of oral feeding, following major surgery for UGI cancer on postoperative complications, postoperative length of hospital stay (LOS), nutritional status and quality of life (QOL). The literature was searched up to March 9th 2020 using CINHAL, PubMed, MEDLINE, Embase, Scopus and Web of Science databases. Quality assessment was completed using the Academy of Nutrition and Dietetics quality criteria checklist. Fifteen articles were included, consisting of seven randomised controlled trials, six cohort studies and two non-randomised trials, with a total of 2517 participants. The type and timing of EOF varied considerably across studies with limited reporting of energy and protein intakes from oral or enteral feeding. Fourteen studies assessed postoperative complications of which 13 reported no difference between EOF and standard care. Fourteen studies assessed postoperative LOS and of these, 13 reported a reduced length of stay in the EOF group. Four of 15 studies assessing nutritional status found no difference between groups. Three of 15 studies assessed QOL with inconsistent findings. This review found EOF reduced postoperative LOS and did not increase postoperative complications. However, the optimal timing for the introduction of EOF could not be established. Furthermore, the type of EOF varied considerably making comparison across studies challenging and demonstrates a need for internationally standardised definitions.

Effect of an Evidence-Based Nutrition Care Pathway for Cancer Patients Undergoing Gastrointestinal and Pelvic Surgery.

Malnutrition in gastrointestinal surgery is associated with poorer post-operative outcomes which may be mitigated by delivery of evidence-based nutrition care. This study reports on the development, implementation and evaluation of an evidence-based nutrition care pathway for lower gastrointestinal and pelvic cancer patients. A retrospective cohort study of 40 surgical lower gastrointestinal and pelvic cancer patients pre- and post-implementation of the pathway was conducted. Outcomes assessed were, care pathway adherence, weight change, time to post-operative commencement of nutrition, and post-operative length of stay. Post-implementation of the pathway there were significant improvements in the proportion of patients who received dietetic assessment and education pre-surgery (0% vs 55%, P < .001) at regular intervals during admission (35% vs. 90%, P < .001) and post-discharge (22.5% vs. 81.8%, P < .001). Mean weight change between admission and discharge reduced post-implementation (-3.5%, SD 4.7 vs, -5.6%, SD 4.7; P = 0.08). Post-operative length of stay remained similar (16 day, IQR 11-34.7 vs. 17.5 day, IQR 11.2-25; P = 0.71). Post-implementation a greater proportion of patients commenced oral or enteral nutrition within 24 h, post-operatively (75% vs. 57.5%, P = 0.1). The nutrition care pathway was an effective method for delivering evidence-based nutrition care, resulting in clinically but not statistically significant improvements in outcomes.

Health-related quality of life, fatigue and health behaviours in Australian adolescent and young adult cancer survivors.

INTRODUCTION: Current knowledge of the long-term health behaviours and well-being of adolescent and yong adult (AYA) cancer survivors is limited. The aim of this study was to evaluate the health behaviours of AYA cancer survivors compared to Australian normative data and describe their health-related quality of life (HR-QoL) and levels of fatigue. METHOD: A cross-sectional online survey of participants aged 15-25 years at diagnosis and 2-7 years post treatment completion was conducted at a comprehensive cancer centre. Validated questionnaires assessed health behaviours and functioning including current physical activity (PA) levels, diet quality, fatigue (FACIT-F) and HR-QoL (AQoL-6D, Short Form 36v2 [SF-36v2]) were compared to Australian normative data. RESULTS: Ninety individuals completed the survey (26% response rate) with a mean age of 25.4 years and median time post treatment of 61 months (24-85 months). Compared to normative data, a higher proportion of AYA cancer survivors was consuming the recommended daily serves of fruit and vegetables (16.7% vs. 3.9%, p < .0001), had a lower presence of overweight or obesity (46.7% vs. 57.7%, p = .04) and lower percentage of current smokers (2.2% vs. 16.7%, p < .0001). However, AYA cancer survivors reported increased fatigue (t[df = 596] = -4.1, p < .0001) and reduced HR-QoL compared to normative data (t[df = 533] = 9.2, p < .0001) along with a higher proportion suffering from one or more chronic health conditions (65% vs. 40%, p < .0001). CONCLUSION: AYA cancer survivors from a single Australian institution, who were on average 5 years post treatment, exhibited better health behaviours compared to Australian normative data, but still below recommended guidelines. However, they continue to experience issues with fatigue and reduced HR-QoL, especially in those not meeting the PA guidelines.

Patient and carer experiences of nutrition in cancer care: a mixed-methods study.

PURPOSE: Evidence-based guidelines exist to guide health professionals and services about cancer nutrition care; however, the views of cancer patients and carers are not well understood. This study aimed to understand the experience and needs of cancer patients and carers regarding nutrition care across the care continuum. METHODS: Using a mixed-methods approach, cancer patients and carers completed a cross-sectional online survey and focus groups. Participants were recruited through health services and cancer organisation consumer networks via email distribution lists, e-newsletters, and social media. Focus groups were audio-recorded, transcribed, and analysed using content analysis. RESULTS: Of 165 survey respondents, only 51% (n=84) reported they talked to a health professional about their nutrition care at any time-point, and only 32% with a dietitian. The majority (84%) of patients and carers felt nutrition was important at one or more time-points in their cancer path, indicating during and after cancer treatment the most important. However, perceived support from health professionals for nutrition care was deemed low at all time-points. Five focus groups were held (n=20; 16 patients, 2 carers, 2 both patients/carers) and five themes emerged: nutrition information, experiences and need; control over diet and nutrition; importance and value of nutrition; access to support; what optimal nutrition care looks like. CONCLUSION: Patients and carers felt nutrition was important during their cancer path, but perceived support from health professionals for nutrition care was low. This study has highlighted patient and carer nutrition experiences that will inform development of a co-designed optimal cancer nutrition care pathway.

Comparison of segmental lean tissue mass in individuals with spinal cord injury measured by dual energy X-ray absorptiometry and predicted by bioimpedance spectroscopy.

STUDY DESIGN: Observational. OBJECTIVES: To compare two methods for predicting segmental (arms, legs, trunk) lean tissue mass (LTM: non-bone fat-free mass) from bioimpedance spectroscopy (BIS) against LTM measured from dual energy X-ray absorptiometry (DXA) in individuals with acute spinal cord injury (SCI). SETTING: Austin Health Victorian Spinal Cord Service, Victoria, Australia. METHODS: Fourteen participants (two female), within 8 weeks of traumatic SCI had BIS measured following an overnight fast and within 24 h of DXA scanning. Total body fat-free mass (FFM, body weight minus fat mass) and segmental LTM were predicted from BIS using manufacturer's proprietary software and a previously established SCI-specific prediction method. Appendicular LTM (ALM) was calculated from the sum of the LTM of the arms and legs. Agreement and strength of relationships with DXA for predicted LTM measures using both approaches were assessed using Lin's concordance coefficient and limits of agreement analysis (LOA). RESULTS: The BIS proprietary method performed better than the SCI-specific prediction method in predicting DXA LTM, demonstrating substantial concordance for total body FFM (rc = 0.80), ALM (rc = 0.78), arm (rc = 0.76) and leg LTM (rc = 0.65) and a smaller bias and LOA for ALM (+0.8 vs. -3.4 kg; LOA -4.9-6.4 vs. -11.9-5.1 kg), arm (+0.02 vs. -0.3 kg; LOA -1.1-1.1 kg vs. -2.2-1.6 kg) and leg (+0.4 vs. -1.4 kg; LOA -2.0-2.8 vs. -5.6-2.8) LTM. CONCLUSIONS: BIS can be used to accurately predict total body FFM, segmental LTM and ALM in individuals with acute SCI.

Nutritional Complications and the Management of Patients with Gastroenteropancreatic Neuroendocrine Tumors.

Neuroendocrine tumors (NETs) have increased in incidence and prevalence over the past 2 decades and affect approximately 170,000 people in the United States alone. Gastroenteropancreatic (GEP) NETs (GEP NET) are a heterogeneous group of rare tumors that have distinct effects on the body due to their tumor location and potential to secrete hormones and peptides. Clinical practice guidelines and consensus guidelines for GEP NETs with regard to best practice for diagnosis, treatment, and medical management are available, but the supportive care needs and optimal nutritional management of patients affected by these unique tumors remain under-researched: evidence to guide clinical practice is lacking. The pathophysiology of the disease and its treatment can cause various symptoms that can have significant effects on vitamin synthesis and absorption, dietary habits, weight change, and appetite. Deficiency of fat-soluble vitamins and niacin exists amongst patients with GEP NET, particularly those on treatment with somatostatin analogs and with serotonin-secreting tumors, respectively. Malnutrition and dietary modification amongst patients with GEP NET is more prevalent than initially thought: up to 25% of inpatients with GEP NET are malnourished. Food intolerance is also reported in up to 40-90% of these patients, though its misdiagnosis is common. This review summarizes the evidence regarding the impact of GEP NET and its treatment on nutritional factors in these patients with emphasis on malnutrition, vitamin deficiencies, dietary intake, and quality of life. Recommendations for clinical practice and research approaches to address these nutritional issues are discussed.

Awareness, perceptions and practices regarding cancer-related malnutrition and sarcopenia: a survey of cancer clinicians.

PURPOSE: Cancer-related malnutrition and sarcopenia have severe negative consequences including reduced survival and reduced ability to complete treatment. This study aimed to determine the awareness, perceptions and practices of Australian oncology clinicians regarding malnutrition and sarcopenia in people with cancer. METHODS: A national cross-sectional survey of Australian cancer clinicians was undertaken between November 2018 and January 2019. The 30-item online purpose-designed survey was circulated through professional organizations and health services. RESULTS: The 111 participants represented dietetic (38%), nursing (34%), medical (14%) and other allied health (14%) clinicians. Overall, 86% and 88% clinicians were aware of accepted definitions of malnutrition and sarcopenia, respectively. Perception of responsibility for identification of these conditions varied across participants, although 93% agreed this was a component of their role. However, 21% and 43% of clinicians had limited or no confidence in their ability to identify malnutrition and sarcopenia, respectively. Common barriers to the identification and management of malnutrition were access to the tools or skills required and a lack of services to manage malnourished patients. Common barriers to identification of sarcopenia were lack of confidence and lack of services to manage sarcopenic patients. Enablers for identification and management of malnutrition and sarcopenia were variable; however, training and protocols for management ranked highly. CONCLUSION: While awareness of the importance of cancer-related malnutrition and sarcopenia are high, participants identified substantial barriers to delivering optimal nutrition care. Guidance at a national level is recommended to strengthen the approach to management of cancer-related malnutrition and sarcopenia.

Exercise and Nutritional Approaches to Combat Cancer-Related Bone and Muscle Loss.

PURPOSE OF REVIEW: The aim of this narrative review is to summarise recent literature on the effects of exercise and nutrition interventions alone or in combination on muscle and bone loss in people with cancer. RECENT FINDINGS: There is emerging evidence to support the inclusion of targeted exercise and nutrition strategies to counter loss of muscle and bone associated with cancer treatments. Although research in this field is advancing, the optimal exercise and nutrition prescription to combat cancer-related bone and muscle loss remain unknown. This review identifies specific components of nutrition and exercise interventions that are promising although require further exploration through studies designed to determine the effect on muscle and bone. A focused research effort is required to elucidate the full potential of exercise and nutrition intervention for people with cancer at risk of bone and muscle loss.

Early Skeletal Muscle Loss in Non-Small Cell Lung Cancer Patients Receiving Chemoradiation and Relationship to Survival.

PURPOSE: Sarcopenia is associated with reduced survival in cancer. Currently, data on sarcopenia at presentation and muscle loss throughout treatment are unknown in patients receiving chemoradiation therapy (CRT) for non-small cell lung cancer (NSCLC). This study evaluated skeletal muscle changes in NSCLC patients receiving CRT and relationship with survival. METHODS: Secondary analysis of 41 patients with NSCLC treated with CRT assessed for skeletal muscle area and muscle density by computed tomography pre-treatment and 3 months post-treatment. Images at week 4 of treatment were available for 32 (78%) patients. Linear mixed models were applied to determine changes in skeletal muscle over time and related to overall survival using Kaplan-Meier plots. RESULTS: Muscle area and muscle density decreased significantly by week 4 of CRT (- 6.6 cm2, 95% CI - 9.7 to - 3.1, p < 0.001; - 1.3 HU, 95% CI - 1.9 to - 0.64, p < 0.001, respectively), with minimal change between week 4 of CRT and 3 months post-CRT follow-up (- 0.2 cm2, 95% CI - 3.6-3.1, p = 0.91; - 0.27, 95% CI - 0.91-0.36, p = 0.36, respectively). Sarcopenia was present in 25 (61%) and sarcopenic obesity in 6 (14%) of patients prior to CRT, but not associated with poorer survival. Median survival was shorter in patients with low muscle density prior to treatment although not statistically significant (25 months + 8.3 vs 53 months + 13.0, log-rank p = 0.17). CONCLUSION: Significant loss of muscle area and muscle density occurs in NSCLC patients early during CRT. A high proportion of patients are sarcopenic prior to CRT; however, this was not significantly associated with poorer survival.

Implementing and sustaining an evidence-based nutrition service in a haematology unit for autologous stem cell transplant patients.

PURPOSE: Effective, timely and evidence-based nutritional management is important in patients receiving autologous haematopoietic stem cell transplant (HSCT) to prevent the negative consequences of developing malnutrition. This study describes a robust process for development and implementation of an evidence-based nutrition care pathway for HSCT patients in a tertiary cancer centre. METHODS: A comprehensive review of the literature was completed to identify relevant articles and evidence-based guidelines to inform the development of the pathway. Evidence from the literature review was assessed and utilised to underpin the development of pathway. The pathway was implemented in the haematology service in collaboration with the multidisciplinary haematology team. Dietetic resource requirements for implementation of the pathway were determined and clinician compliance with the care pathway was assessed to evaluate the feasibility of the pathway in supporting delivery of evidence-based care. RESULTS: The evidence-based care pathway was implemented in 2011 with the final care pathway based on recommendations from five international evidence-based guidelines. Overall clinician compliance with delivering nutrition management described in the care pathway was high at 84%. The dietetic resource requirement for implementation of the care pathway was 300 to 400 h per 100 patients depending on conditioning chemotherapy regimen. CONCLUSION: A robust process for developing and implementing a nutrition care pathway for HSCT patients was effective in supporting the delivery of evidence-based nutritional management for patients treated with HSCT.

Early and Intensive Dietary Counseling in Lung Cancer Patients Receiving (Chemo)Radiotherapy-A Pilot Randomized Controlled Trial.

Malnutrition is prevalent in patients undergoing (chemo)radiotherapy (RT) for lung cancer. This pilot study tested the feasibility and acceptability of delivering an intensive nutrition intervention for lung cancer patients receiving RT. Twenty-four patients with lung cancer were randomized to receive the intervention which employed a care pathway to guide intensive dietary counseling from pretreatment until 6-wk posttreatment or usual care. Nutritional, fatigue, and functional outcomes were assessed using valid and reliable questionnaires before randomization, at the start and end of RT and 1- and 3-mo post-RT. Consent rate was 57% with an overall attrition of 37%. Subject compliance with the completion of study questionnaires was 100%. A clinically important mean difference indicated greater overall satisfaction with nutritional care in the intervention group (5.00, interquartile range [IQR] 4.50-5.00; 4.00, IQR 4.00-4.00). Clinically important differences favoring the intervention were observed for weight (3.0 kg; 95% confidence interval [CI] -0.8, 6.8), fat-free mass (0.6 kg; 95% CI -2.1, 3.3), physical well-being (2.1; 95% CI -2.3, 6.5), and functional well-being (5.1; 95% CI 1.6, 8.6), but all 95% CIs were wide and most included zero. Recruitment feasibility and acceptability of the intervention were demonstrated, which suggest larger trials using an intensive nutrition intervention would be achievable.

The effect of nutrition intervention in lung cancer patients undergoing chemotherapy and/or radiotherapy: a systematic review.

The prevalence of malnutrition in lung cancer patients across a variety of treatment modalities and disease stages ranges from 45% to 69%. Malnutrition is associated with poorer clinical outcomes in cancer patients. This systematic review examined whether dietary counseling or oral supplements during chemotherapy and/or radiotherapy in patients with lung cancer affect patient or clinical outcomes. Relevant nutrition intervention studies from 1980 to March 2012 were identified. Articles meeting predetermined inclusion/exclusion criteria were critically appraised and included in the review. The outcomes of interest included dietary intake, weight, nutritional status, quality of life, functional status, treatment response, and survival. Five eligible studies were identified including 3 randomized controlled trials, 1 historical cohort, and 1 case series. These studies suggest dietary counseling improves energy and protein intake during chemotherapy in patients with lung cancer but has no benefit to other outcomes during chemotherapy. There is insufficient evidence regarding the effect on patient or clinical outcomes during radiotherapy. Randomized trials examining dietary counseling in patients with lung cancer during radiotherapy are required.

Nutritional interventions during treatment for ovarian cancer: A narrative review and recommendations for future research.

Most women with ovarian cancer are diagnosed at an advanced stage (stage III or IV), when the intraabdominal spread of the tumour impacts nutrient intake and absorption. Up to 70 % of women with ovarian cancer are malnourished and approximately 40 % are affected by muscle loss at the time of diagnosis. Women with ovarian cancer are at high risk of nutritional decline due to invasive treatment and the severity of side-effects. This review explores the evidence evaluating nutritional interventions during treatment for ovarian cancer and their effect on nutritional status, muscle mass, and clinical outcomes. Perioperative immunonutrition has been investigated with mixed results for immediate postoperative outcomes. Individualised nutrition counselling as part of a multimodal prehabilitation programme prior to surgery shows promising results; however, the effects are limited by sample size. Nutrition counselling as part of a mixed intervention with exercise shows high acceptability and suggests improvements in dietary intake and quality of life during chemotherapy treatment, while oral nutritional supplements and nutrition education appear to reduce symptom burden. Individualised nutrition counselling during treatment also appears to be associated with improved overall survival; however, the evidence is limited to a single retrospective study. A key finding from this review is that, despite the high prevalence of malnutrition and muscle loss in women with ovarian cancer and the critical importance of addressing these modifiable prognostic factors, nutrition intervention studies are limited. Prospective studies with samples large enough to provide adequate power to evaluate intervention effectiveness are urgently required to inform optimal management.
