Nutritional screening in a cancer prehabilitation programme: A cohort study.

BACKGROUND: Cancer patients are often malnourished pre-operatively. The present study aimed to establish whether current screening was appropriate for use in prehabilitation and investigate any association between nutritional risk, functionality and quality of life (QoL). METHODS: This cohort study used routinely collected data from September 2020 to August 2021 from patients in a Prehab4cancer programme. Included patients were aged ≥ 18 years, had colorectal, lung or oesophago-gastric cancer and were scheduled for surgery. Nutritional assessment included Patient-Generated Subjective Global Assessment (PG-SGA) Short-Form and QoL with a sit-to-stand test. Association between nutritional risk and outcomes was analysed using adjusted logistic regression. RESULTS: From 928 patients referred to Prehab4Cancer service over 12 months, data on nutritional risk were collected from 526 patients. Pre-operatively, 233 out of 526 (44%) patients were at nutritional risk (score ≥ 2). During prehabilitation, 31% of patients improved their PG-SGA and 74% of patients maintained or improved their weight. Odds ratios (OR) with confidence intervals (CI) showed that patients with better QoL using EuroQol-5 Dimensions (OR = 0.05, 95% CI = 0.01, 0.45, p = 0.01), EuroQol Visual Analogue Scale (OR = 0.96, 95% CI = 0.93, 1.00, p = 0.04) or sit-to-stand (OR = 0.96, 95% 0.93, 1.00, p = 0.04) were less likely to be nutritional at risk. CONCLUSIONS: Almost half of patients in Prehab4Cancer programme assessed using PG-SGA were at risk of malnutrition. However, almost half of the sample did not have their risk assessed. Patients at risk of malnutrition were more likely to have a poorer QoL and sit-to-stand test than those who were not at risk.

Nutrition in palliative and end-of-life care.

Recent publications regarding nutrition highlight the importance of eating and drinking for patients and their family/carer. This article focuses on the importance of nutrition and early nutritional intervention, giving guidance for nurses when caring for patients with palliative and end-of-life care needs when the focus of nutrition centres around symptom control and quality of life. Clear, sensitive communication, with agreed nutritional goals set with the patient and their family/carer, and regular review and adaptation throughout any 'cancer journey' are paramount in order to minimise anxiety and distress. A multidisciplinary team approach is often required in order to support ethical decision-making and to assist in devising an individualised nutritional management plan. Although this article aims to focus upon the nutritional aspects associated with advancing cancer, many aspects will clearly be transferrable to patients with other life-limiting illnesses such as dementia and advanced cardiac and pulmonary disease.

Prospective Observational Study of Prevalence, Assessment and Treatment of Pancreatic Exocrine Insufficiency in Patients with Inoperable Pancreatic Malignancy (PANcreatic Cancer Dietary Assessment-PanDA).

INTRODUCTION: Pancreatic exocrine insufficiency (PEI) in patients with advanced pancreatic cancer (aPC) is well documented, but there is no consensus regarding optimal screening. METHODS AND ANALYSIS: Patients diagnosed with aPC referred for palliative therapy were prospectively recruited. A full dietetic assessment (including Mid-Upper Arm Circumference (MUAC), handgrip and stair-climb test), nutritional blood panel, faecal elastase (FE-1) and 13C-mixed triglyceride breath tests were performed. PRIMARY OBJECTIVE: prevalence of dietitian-assessed PEI (demographic cohort (De-ch)); design (diagnostic cohort (Di-ch)) and validation (follow-up cohort (Fol-ch)) of a PEI screening tool. Logistic and Cox regressions were used for statistical analysis. RESULTS: Between 1 July 2018 and 30 October 2020, 112 patients were recruited (50 (De-ch), 25 (Di-ch) and 37 (Fol-ch)). Prevalence of PEI (De-ch) was 64.0% (flatus (84.0%), weight loss (84.0%), abdominal discomfort (50.0%) and steatorrhea (48.0%)). The derived PEI screening panel (Di-ch) included FE-1 (normal/missing (0 points); low (1 point)) and MUAC (normal/missing (>percentile 25) (0 points); low (2 points)) and identified patients at high-risk (2-3 total points) of PEI [vs. low-medium risk (0-1 total points)]. When patients from the De-ch and Di-ch were analysed together, those classified by the screening panel as "high-risk" had shorter overall survival (multivariable Hazard Ratio (mHR) 1.86 (95% CI 1.03-3.36); p-value 0.040). The screening panel was tested in the Fol-ch; 78.4% patients classified as "high-risk", of whom 89.6% had dietitian-confirmed PEI. The panel was feasible for use in clinical practice (64.8% patients completed all assessments), with high acceptability (87.5% would repeat it). Most patients (91.3%) recommended dietetic input for all patients with aPC. CONCLUSIONS: PEI is present in most patients with aPC; early dietetic input provides a holistic nutritional overview, including, but not limited to, PEI. This proposed screening panel may help to prioritise those at higher risk of PEI, requiring urgent dietitian input. Its prognostic role needs further validation.

Pancreatic Enzyme Replacement Therapy for Patients Diagnosed With Pancreaticobiliary Cancer: Validation of an Algorithm for Dose Escalation and Management.

OBJECTIVE: An algorithm was designed aiming to provide consistency of pancreatic enzyme replacement therapy (PERT) dosing/titration across healthcare professionals in pancreaticobiliary cancers (PBCs). This prospective observational study aimed to validate this algorithm. METHODS: Consecutive patients with inoperable or postoperative PBC with pancreatic exocrine insufficiency (PEI) symptoms, not taking PERT, or taking below the algorithm "starting dose," were eligible. A dietitian or clinical nurse specialist reviewed patients for up to 3 weeks, titrating PERT as per the algorithm. Feasibility of algorithm deliverability was assessed by the percentage of patients with successful completion (primary objective). RESULTS: Twenty-five patients were eligible (N = 25): at baseline, 22 took PERT (100% on suboptimal doses, 54.5% taking incorrectly) and 3 initiated PERT because of PEI symptoms. Algorithm completion (20 of 25, 80%) confirming deliverability by dietitians (11 of 12, 92%) and clinical nurse specialists (9 of 13, 69%). Symptom resolution occurred in 8 of 19 (42%), 3 of 7 (43%), and 1 of 3 (33%) patients at first, second, and third reviews, respectively; advice compliance was between 63% and 86%. CONCLUSIONS: This algorithm provides a structured method to titrate PERT. At diagnosis, all patients with PBC should be assessed for PEI and adequate PERT initiated. Regular reviews are required for timely symptom resolution and adequate escalation, facilitating differential diagnosis if refractory symptoms exist.

The provision of nutritional support for people with cancer.

Nutritional support is one of the most fundamental aspects of nursing practice. Evidence suggests that many patients are malnourished when admitted to hospital and this is a particular problem for patients with cancer (Whitman, 2000).
