Assessment of Nutritional Status and Nutrition Impact Symptoms in Patients Undergoing Resection for Upper Gastrointestinal Cancer: Results from the Multi-Centre NOURISH Point Prevalence Study

BACKGROUND

Identification and treatment of malnutrition are essential in upper gastrointestinal (UGI) cancer. However, there is limited understanding of the nutritional status of UGI cancer patients at the time of curative surgery. This prospective point prevalence study involving 27 Australian tertiary hospitals investigated nutritional status at the time of curative UGI cancer resection, as well as presence of preoperative nutrition impact symptoms, and associations with length of stay (LOS) and surgical complications.

METHODS

Subjective global assessment, hand grip strength (HGS) and weight were performed within 7 days of admission. Data on preoperative weight changes, nutrition impact symptoms, and dietary intake were collected using a purpose-built data collection tool. Surgical LOS and complications were also recorded. Multivariate regression models were developed for nutritional status, unintentional weight loss, LOS and complications.

RESULTS

This study included 200 patients undergoing oesophageal, gastric and pancreatic surgery. Malnutrition prevalence was 42% (95% confidence interval (CI) 35%, 49%), 49% lost ≥5% weight in 6 months, and 47% of those who completed HGS assessment had low muscle strength with no differences between surgical procedures (p = 0.864, p = 0.943, p = 0.075, respectively). The overall prevalence of reporting at least one preoperative nutrition impact symptom was 55%, with poor appetite (37%) and early satiety (23%) the most frequently reported. Age (odds ratio (OR) 4.1, 95% CI 1.5, 11.5, p = 0.008), unintentional weight loss of ≥5% in 6 months (OR 28.7, 95% CI 10.5, 78.6, p < 0.001), vomiting (OR 17.1, 95% CI 1.4, 207.8, 0.025), reduced food intake lasting 2-4 weeks (OR 7.4, 95% CI 1.3, 43.5, p = 0.026) and ≥1 month (OR 7.7, 95% CI 2.7, 22.0, p < 0.001) were independently associated with preoperative malnutrition. Factors independently associated with unintentional weight loss were poor appetite (OR 3.7, 95% CI 1.6, 8.4, p = 0.002) and degree of solid food reduction of <75% (OR 3.3, 95% CI 1.2, 9.2, p = 0.02) and <50% (OR 4.9, 95% CI 1.5, 15.6, p = 0.008) of usual intake. Malnutrition (regression coefficient 3.6, 95% CI 0.1, 7.2, p = 0.048) and unintentional weight loss (regression coefficient 4.1, 95% CI 0.5, 7.6, p = 0.026) were independently associated with LOS, but no associations were found for complications.

CONCLUSIONS

Despite increasing recognition of the importance of preoperative nutritional intervention, a high proportion of patients present with malnutrition or clinically significant weight loss, which are associated with increased LOS. Factors associated with malnutrition and weight loss should be incorporated into routine preoperative screening. Further investigation is required of current practice for dietetics interventions received prior to UGI surgery and if this mitigates the impact on clinical outcomes.

Blenderized food tube feeding in patients with head and neck cancer

Background

Patients with headand neck cancer (HNC) are at high risk for malnutrition before and during chemoradiation treatment. Many will also require tube feeding to address declines in energy intake, weight, and quality of life (QOL) caused by the impact of treatment on gastrointestinal (GI) symptoms. Blenderized tube feeding (BTF) may ameliorate these adverse conditions.

Methods

In this open‐label, prospective pilot study, 30 patients with HNC who required feeding tube placement were recruited to switch from standard commercial formula after 2 weeks to a commercially prepared BTF formula. Weight, body mass index (BMI), GI symptoms, and QOL scores were tracked for 6 weeks from the first week of feeding tube placement.

Results

Of the 16 patients who completed the 6‐week assessment period, weights and BMI scores for 15 patients trended upward. For most patients, QOL and oral intake increased and GI symptoms decreased over the 6‐week period, particularly during weeks 3 and 4, when the impact of treatment is particularly exacting on patients with HNC.

Conclusion

BTF effectively mitigated weight loss, GI symptoms, QOL scores, and total energy intake in this group of patients with HNC who received tube feeding for 6 weeks.

Diet and Exercise Interventions in Patients With Pancreatic Cancer: A Scoping Review

ABSTRACT

Diet and exercise interventions may help reverse malnutrition and muscle wasting common in pancreatic cancer. We performed a scoping review to identify the knowledge gaps surrounding diet and exercise interventions. We searched PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature, Embase, ProQuest Theses and Dissertations, and Google Scholar using the umbrella terms of "pancreatic cancer," "diet/nutrition," and "exercise." Included were articles reporting on ambulatory adults with diagnosed pancreatic cancer. Excluded were studies examining prevention and/or risk, animal, or cell lines. Of the 15,708 articles identified, only 62 met the final inclusion criteria. Almost half of the articles were randomized controlled studies (n = 27). Most studies were from the United States (n = 20). The majority examined dietary interventions (n = 41), with 20 assessing the use of omega-3 fatty acids. Exercise interventions were reported in 13 studies, with 8 examining a diet and exercise intervention. Most studies were small and varied greatly in terms of study design, intervention, and outcomes. We identified 7 research gaps that should be addressed in future studies. This scoping review highlights the limited research examining the effect of diet and exercise interventions in ambulatory patients with pancreatic cancer.

utritional Outcomes of patients Undergoing Resection for upper gastroIntestinal cancer in AuStralian Hospitals (NOURISH): protocol for a multicentre point prevalence study

INTRODUCTION

Nutritional intervention and prevention of malnutrition is significantly important for patients with upper gastrointestinal oesophageal, pancreatic and gastric cancer. However, there is limited information regarding nutritional status, and perioperative nutritional interventions that patients receive when undergoing curative surgery.

METHODS AND ANALYSIS

Patients diagnosed with upper gastrointestinal cancer, planned for curative intent resection across 27 Australian hospitals will be eligible to participate in this point prevalence study. The primary aim is to determine the prevalence of malnutrition in patients with upper gastrointestinal cancer at the time of surgery using subjective global assessment. Secondary aims are to determine the type and frequency of perioperative nutritional intervention received, the prevalence of clinically important weight loss and low muscle strength, and to investigate associations between the use of an evidence-based nutrition care pathway or protocol for the nutritional management of upper gastrointestinal surgical oncology patients and malnutrition prevalence. Data collection will be completed using a purpose-built data collection tool.

ETHICS AND DISSEMINATION

Ethical approval was granted in May 2019 (LNR/51107/PMCC-2019). The design and reporting of this study comply with the Strengthening the Reporting of Observational Studies in Epidemiology checklist for reporting of observational cohort studies. Findings will be published in peer-reviewed scholarly journals and presented at relevant conferences. Results will assist in defining priority areas for research to improve patient outcomes.

Nutritional management of patients with oesophageal cancer throughout the treatment trajectory: benchmarking against best practice

PURPOSE

Oesophageal cancer (OC) impacts nutritional status and outcomes. This study aims to benchmark the current nutrition management of patients with OC against best practice recommendations, identify critical points in the treatment trajectory where nutritional status is compromised, service gaps and opportunities for improvement.

METHODS

A retrospective audit collected demographic, medical and nutritional data from medical records of patients who received curative treatment for OC at a tertiary referral hospital in Sydney, Australia.

RESULTS

Thirty-seven patient records were audited over the time period. Twenty-nine patients underwent nutrition screening on admission to the service. Eighteen out of 25 patients receiving neoadjuvant radiation therapy, all patients during surgical admission, and only 19 patients at postsurgical discharge were seen by a dietitian. All patients received tube feeding post-operatively; however, initiation within 24 h only occurred for 14 patients. Weight significantly declined over the course of treatment (p < 0.001), whilst malnutrition during surgical admission (p = 0.004) and postsurgical discharge (p = 0.038) were both associated with significantly higher unplanned readmissions.

CONCLUSIONS

Best practice recommendations were met for aspects of the immediate post-operative period; however, service gaps remain during pre-operative and post-discharge care. Findings from this study indicate that nutritional care is inconsistent across different treatment stages, and malnutrition impacts negatively on unplanned readmission. Research is needed to address evidence-practice gaps, assess appropriateness of recommendations and provide evidence for models of care during multimodality treatments and across different services.

A process and mechanism of action evaluation of the effect of early and intensive nutrition care, delivered via telephone or mobile application, on quality of life in people with upper gastrointestinal cancer: a study protocol

BACKGROUND

Cancers of the upper gastrointestinal tract commonly result in malnutrition, which increases morbidity and mortality. Current nutrition best practice lacks a mechanism to provide early and intensive nutrition support to these patients. A 3-arm parallel randomised controlled trial is testing the provision of a tailored, nutritional counselling intervention delivered using a synchronous, telephone-based approach or an asynchronous, mobile application-based approach to address this problem. This protocol outlines the design and methods that will be used to undertake an evaluation of the implementation process, which is imperative for successful replication and dissemination.

METHODS

A concurrent triangulation mixed methods comparative analysis will be undertaken. The nutrition intervention will be provided using best practice behaviour change techniques and communicated either via telephone or via mHealth. The implementation outcomes that will be measured are: fidelity to the nutrition intervention protocol and to the delivery approach; engagement; acceptability and contextual factors. Qualitative data from recorded telephone consultations and written messages will be analysed through a coding matrix against the behaviour change techniques outlined in the standard operating procedure, and also thematically to determine barriers and enablers. Negative binomial regression will be used to test for predictive relationships between intervention components with health-related quality of life and nutrition outcomes. Post-intervention interviews with participants and health professionals will be thematically analysed to determine the acceptability of delivery approaches. NVivo 11 Pro software will be used to code for thematic analysis. STATA version 15 will be used to perform quantitative analysis.

DISCUSSION

The findings of this process evaluation will provide evidence of the core active ingredients that enable the implementation of best practice nutrition intervention for people with upper gastrointestinal cancer. Elucidation of the causal pathways of successful implementation and the important relationship to contextual delivery are anticipated. With this information, a strategy for sustained implementation across broader settings will be developed which impact the quality of life and nutritional status of individuals with upper gastrointestinal cancer.

Pancreatic enzyme replacement therapy following surgery for pancreatic cancer: An exploration of patient self-management

BACKGROUND

For those diagnosed with pancreatic cancer, ill-addressed pancreatic exocrine insufficiency (PEI) following surgery can result in malnutrition related complications that may impact on predict mortality and morbidity. The use of pancreatic enzyme replacement therapy (PERT) is recommended and often demands a degree of patient self-management. Understanding more about how this treatment is managed is fundamental to optimising care.

OBJECTIVE

This study aimed to explore patient self-management of PERT following surgery for pancreatic cancer.

METHODS

Semi-structured interviews were conducted with nine participants. Eligible participants included adult patients who had undergone surgery for a malignancy in the pancreatic region and were prescribed PERT post-operatively. Inductive thematic analysis was used to analyse our findings.

RESULTS

Data analysis revealed three overarching themes; the role of professional support, factors influencing decisions to use PERT in symptom management and the challenges of socializing. The difficulties negotiated by participants were considerable as they struggled with the complexities of PERT. Symptom management and subsequently reported physical repercussions and undesirable social implications were problematic. Professional support was largely inconsistent and relinquished prematurely following discharge. Consequently, this impacted on how PERT was self-managed.

CONCLUSION

Enabling patients to appropriately self-manage PERT may lessen the post-treatment burden. Our findings suggest that support should continue throughout the recovery phase and should address the patient's 'self-management journey'. Intervention by healthcare professionals, such as a specialist dietitian is likely to be beneficial. Furthermore there are focal issues, primarily explicit education and appropriately timed information that require consideration by those developing and delivering services.

Long-Term Nutritional Outcome and Health Related Quality of Life of Patients Following Esophageal Cancer Surgery: A Meta-Analysis

Long term health related quality of life (HRQL) and nutritional outcome of patients following esophagectomy for cancer has become increasingly significant as the 5-year survival rate in this patient group is increasing. This meta-analysis aims to investigate the HRQOL, nutritional impact symptoms and nutritional outcomes of patients following an esophagectomy at greater than 12 months after surgery. In studies reporting on HRQL as an outcome, global QOL score at 6-month compare to greater than 12-month showed no statistically significant difference (65.92 vs. 75.78, p = 0.07). Forty-one percent of patients reported a greater than 10% weight loss at six-month follow-up (95% CI: 20-65%; I2 = 94.27, p < 0.001), and at the greater than 12-month follow-up, 33% of patients had the greater than 10% weight loss (95% CI: 15-57%; I2 = 96.18, p < 0.001). At the 12-month or longer post esophagectomy, just over half the patients reported dysphagia (51%, 95% CI: 25-76%; I2 = 95.70, p < 0.001), nausea was reported by 11% (95% CI: 7-19%; I2 = 59.31, p = 0.09), dumping syndrome reported by 60% (95% CI: 43-76%; I2 = 96.92, p < 0.001). Symptoms such as dysphagia, diarrhea, reflux, dumping syndrome, and nausea were found to persist following esophagectomy. There were insufficient robust research investigating how these symptoms impact on the adequacy of dietary intake and micronutrient status.
