The impact of nutrition support on body composition in cancer outpatients receiving radiotherapy

Oral nutritional supplementation in cancer patients: A systematic review and dose-response meta-analysis

BACKGROUND & AIMS

We performed this systematic review and dose-response meta-analysis of randomized clinical trials (RCTs) to determine the effects of oral nutritional supplements (ONS) in cancer patients undergoing chemo (radio) therapy on body weight, body mass index (BMI), serum albumin, fatigue, quality of life (QOL), patient-generated subjective global assessment (PG-SGA) score and C-reactive protein (CRP).

METHODS

Appropriate search terms were used for systematic search in PubMed, Scopus, and Web of Science, till April 2024. Both pairwise and dose-response meta-analyses were done. Random effects model was applied for analyses.

RESULTS

We found that ONS administration significantly improved weight gain [weighted mean difference (WMD): 1.18 kg; 95 % CI, 0.20 to 2.17, P = 0.019; I2 = 56.2 %, PQ-test = 0.002], fatigue scores [standard mean difference (SMD): -1.45; 95 % CI, -2.48 to -0.42, P = 0.006; I2 = 90.1 %, PQ-test< 0.001], PG-SGA scores (WMD: -1.11; 95 % CI, -2.93 to 0.70, P = 0.229; I2 = 72.4 %, PQ-test = 0.001), and QOL (SMD: 1.38; 95 % CI, 0.45 to 2.31; P < 0.001; I2 = 94.4 %, PQ-test< 0.001). The dose-response meta-analysis found a significant relationship between each 200 ml/d increase in ONS and improvement in fatigue (SMD: -7.30; 95 % CI, -10.17 to -4.42, P < 0.001; I2 = 97 %, PQ-test< 0.001) and QOL scores (SMD:7.01; 95 % CI, 3.89 to 10.12, P = 0.001; I2 = 98.3 %, PQ-test < 0.001). Based on a non-linear dose-response meta-analysis, the most significant reduction in fatigue was observed at ONS dosages of ≥400 ml/day, while the most significant improvement in QOL score was seen at ≥ 500 ml/day dosages. Our analysis also showed a significant association between higher albumin levels and ONS intake of ≥200 ml daily.

CONCLUSIONS

In conclusion, ONS can help improve various cancer-related complications; however, further good-quality research is still needed. The study found that ONS significantly improves QoL, reduces fatigue, and promotes body weight gain in cancer patients. However, there were no significant effects on BMI, serum albumin, CRP, or PG-SGA scores.

Prevention of weight loss in patients with head and neck cancer in ongoing radiation or chemoradiation therapy-A systematic review and meta-analysis

PURPOSE

This systematic review (PROSPERO: CRD4202345740) identified and synthesised existing evidence on nutrition interventions performed by healthcare professionals, and the contents of the interventions that prevented weight loss in patients with HNC undergoing RT/CRT.

METHODS

We included quantitative studies. PubMed, CINAHL, Cochrane Library, and Scopus were searched, and the outcomes of interest were weight change and nutritional status. A narrative synthesis was undertaken to elaborate on the findings across the included studies. Furthermore, a meta-analysis was conducted.

RESULTS

A total of 27 studies were identified. Most focused on the effect of oral nutritional supplements (ONS) and individualised nutrition counselling (INC). A beneficial effect of ONS combined with weekly INC were identified, and compliance, management of adverse effects, involvement of family as well as the knowledge and approach of the healthcare professionals were identified as key elements when supporting the management of nutrition intake in HNC patients during RT/CRT. The meta-analysis showed a non-significant effect of ONS, yet significant when combined with INC, and no overall effect of INC, but significant effect in the RCTs.

CONCLUSION

Our results suggest an optimal effect of ONS combined with weekly INC, requiring a focus on enhancing compliance as well as support from a multidisciplinary team to manage adverse treatment effects. Compliance must be emphasised to provide maximum support to the patient, as well as focus on the knowledge of the health care professionals performing the intervention. Further research on strategies to enhance patient compliance and involvement is needed.

Dietary Counseling Interventions During Radiation Therapy: A Systematic Review of Feasibility, Safety, and Efficacy

Radiotherapy is a common cancer treatment, and concurrent nutritional interventions can maintain nutritional status and improve clinical and supportive care outcomes. However, optimal nutritional interventions during radiotherapy are not firmly established. Herein, we assessed the feasibility, safety, and efficacy of dietary counseling interventions without oral nutrition supplements on health outcomes in adults receiving radiotherapy for cancer in a systematic review. Prospective clinical trials that implemented nutritional counseling interventions during radiotherapy were identified from four databases from inception through December 2023. Feasibility, safety, and efficacy were extracted from 32 articles that described 23 randomized and 4 non-randomized clinical trials. The interventions included individualized nutritional counseling (n = 14 articles), nutritional counseling plus exercise (n = 4), and nutritional counseling focused on increasing or reducing intake of specific nutrients (n = 9). Trials targeted head and neck (n = 12), pelvic cancers (n = 14), and/or breast (n = 5) cancers. Control groups had variable designs and included general nutrition education and intervention as needed. Studies recruited 120 ± 104 participants (range 26-468). Interventions tended to be feasible regarding retention and attendance at sessions, though feasibility metrics varied among different interventions. Most interventions were safe with no studies reporting adverse events attributable to dietary intervention. Individualized dietary counseling interventions tended to lead to between-group differences favoring the intervention group in regard to improved nutritional status, maintenance or attenuation of loss of body mass, improved quality of life, and reduced radiation-induced toxicities. Diets that encouraged/discouraged specific nutrients tended to recruit patients receiving radiation to the pelvic area and resulted in positive or neutral effects on gastrointestinal symptoms. In conclusion, nutritional interventions appear to be feasible, safe, and effective during radiotherapy for various symptom outcomes.

Body composition and dietary intake in patients with head and neck cancer during radiotherapy: a longitudinal study

OBJECTIVES

To investigate the body composition and dietary intake in the patients with head and neck cancer (HNC) during radiotherapy (RT), and explore the relationship between them.

METHODS

This was a prospective, longitudinal observational study. Adult patients with HNC undergoing RT between March 2017 and August 2018 were recruited. Patients' body compositions were evaluated by bioelectrical impedance analysis, and dietary intake was recorded by 24-hour dietary recall at three time points, including baseline (T1), mid-treatment (T2) and post-treatment (T3). Patients were divided into low, middle and high energy intake groups based on the average daily energy intake (DEI). Changes in body weight (BW), fat mass (FM), fat-free mass (FFM) and skeletal muscle mass (SMM) among these three groups were compared.

RESULTS

From T1 to T3, the median loss of patients' BW, FM, FFM and SMM was 4.60, 1.90, 2.60 and 1.50 kg, respectively. The loss of BW was more dramatic from T2 to T3 than that from T1 to T2. BW loss was mainly contributed by SMM loss from T1 to T2 and by FM loss from T2 to T3. Meanwhile, patients' dietary intake reduced during treatment. High DEI group had a significantly attenuated loss of patients' BW, FFM, SMM and FM compared with the low DEI group.

CONCLUSION

Patients' BW, FM, FFM and SMM all significantly reduced, especially from T2 to T3, with decreased DEI during RT, which stresses the importance of nutrition intervention during the whole course of RT.

Life style and interaction with microbiota in prostate cancer patients undergoing radiotherapy: study protocol for a randomized controlled trial

Background

Prostate cancer (PCa) is the second most common cancer in men worldwide. The standard non-surgical approach for localized PCa is radiotherapy (RT), but one of the limitations of high-dose RT is the potential increase in gastrointestinal and genitourinary toxicities. We present the protocol of the Microstyle study, a multicentre randomized two-arm crossover clinical trial. The primary outcome will be assessed at the end of 6-month intervention, by measuring the change in adherence to a healthy lifestyle score. The hypothesis is that modifying lifestyle we change microbiome and improve quality of life and decrease side effects of RT.

Methods

Study participants will be recruited among men undergoing RT in two Italian centers (Milan and Naples). We foresee to randomize 300 patients in two intervention arms: Intervention Group (IG) and Control Group (CG). Participants allocated to the IG will meet a dietitian and a physiotherapist before RT to receive personalized diet and exercise recommendations, according to their health status, to improve overall lifestyle and reduce side effects (bowel and/or urinary problems). Dietitian and physiotherapist will work together to set individualized goals to reduce or eliminate side effects and pain according to their health status. All participants (IG) will be given a pedometer device (steps counter) in order to monitor and to spur participants to increase physical activity and reduce sedentary behavior. Participants included in the CG will receive baseline general advice and materials available for patients undergoing RT. According to the cross-over design, the CG will cross to the intervention approach after 6-month, to actively enhance compliance towards suggested lifestyle recommendations for all patients.

Discussion

This trial is innovative in its design because we propose a lifestyle intervention during RT, that includes both dietary and physical activity counselling, as well as monitoring changes in microbiome and serum biomarkers. The promotion of healthy behaviour will be initiated before initiation of standard care, to achieve long lasting effects, controlling side effects, coping with feelings of anxiety and depression and improve efficacy of RT.

Impact of musculoskeletal degradation on cancer outcomes and strategies for management in clinical practice

The prevalence of malnutrition in patients with cancer is one of the highest of all patient groups. Weight loss (WL) is a frequent manifestation of malnutrition in cancer and several large-scale studies have reported that involuntary WL affects 50-80% of patients with cancer, with the degree of WL dependent on tumour site, type and stage of disease. The study of body composition in oncology using computed tomography has unearthed the importance of both low muscle mass (sarcopenia) and low muscle attenuation as important prognostic indications of unfavourable outcomes including poorer tolerance to chemotherapy; significant deterioration in performance status and quality of life (QoL), poorer post-operative outcomes and shortened survival. While often hidden by excess fat and high BMI, muscle abnormalities are highly prevalent in patients with cancer (ranging from 10 to 90%). Early screening to identify individuals with sarcopenia and decreased muscle quality would allow for earlier multimodal interventions to attenuate adverse body compositional changes. Multimodal therapies (combining nutritional counselling, exercise and anti-inflammatory drugs) are currently the focus of randomised trials to examine if this approach can provide a sufficient stimulus to prevent or slow the cascade of tissue wasting and if this then impacts on outcomes in a positive manner. This review will focus on the aetiology of musculoskeletal degradation in cancer; the impact of sarcopenia on chemotherapy tolerance, post-operative complications, QoL and survival; and outline current strategies for attenuation of muscle loss in clinical practice.

Exercise and Nutrition Interventions in Patients with Head and Neck Cancer during Curative Treatment: A Systematic Review and Meta-Analysis

The aim of this meta-analysis was to examine the effects of nutritional and physical exercise interventions and interventions combining these interventions during radiotherapy treatment for patients with head and neck cancer on body composition, objectively measured physical function and nutritional status. Systematic electronic searches were conducted in MEDLINE (PubMed interface), EMBASE (Ovid interface), CINAHL (EBSCO interface) and Cochrane Library (Wiley interface). We identified 13 randomized controlled trials (RCTs) that included 858 patients. For body composition, using only nutrition as intervention, a significant difference between treatment and control group were observed (SMD 0.42 (95CI 0.23-0.62), p < 0.001). Only pilot RCTs investigated combination treatment and no significant difference between the treatment and control groups were found (SMD 0.21 (95CI -0.16-0.58), p = 0.259). For physical function, a significant difference between treatment and control group with a better outcome for the treatment group were observed (SMD 0.78 (95CI 0.51-1.04), p < 0.001). No effects on nutritional status were found. This meta-analysis found significantly positive effects of nutrition and physical exercise interventions alone in favor of the treatment groups. No effects in studies with combined interventions were observed. Future full-scaled RCTs combining nutrition and physical exercise is warranted.

Body Composition Evaluation in Head and Neck Cancer Patients: A Review

Introduction: Head and neck cancer (HNC) patients show a high risk of malnutrition due to the lifestyle habits adopted prior to the diagnosis as well as to the compromising impact of both the anatomical location of the tumor and the treatment modalities on food intake. Weight change, measurement of skinfold thickness, biochemical parameters, bioelectrical impedance analysis (BIA), computed tomography (CT), magnetic resonance (MRI), or dual-energy x-ray absorptiometry (DXA) are available techniques to evaluate nutritional status and/or body composition in the clinical practice. Evaluating body composition alterations in HNC patients is essential to be able to offer the best therapeutical interventions. In this paper, we review the existing literature regarding body composition evaluation in HNC patients to determine, which is the most suitable method for this population, regarding availability in the day-to-day practice, patient burden, cost, sensibility, and specificity.

Methodology: A literature search for relevant papers indexed in MEDLINE, Cochrane Library and Scielo was conducted, with no publication date restriction and for all published articles until the 31 January, 2019. All the papers written in English, with interventions in humans, exclusively considering HNC patients were selected.

Results: A total of 41 studies with different methodologies were included in this review. In 15 studies BIA was the used assessment method and three of them also evaluated skinfold thickness and one was a bioelectric impedance vector analysis (BIVA). Body composition assessment was made with DXA in eight studies, one of which also included muscle biopsies. In two studies the chosen method was both BIA and DXA. CT/ positron emission tomography-CT was applied in 11 studies and one also included MRI. In two studies body composition was assessed with skinfold measurements alone and one study only used BIVA.

Conclusions: Despite the different existing body composition assessment tools, it seems that skeletal muscle mass (SMM) measurement at the level of cervical spine C3 vertebra may be a reliable method for SMM assessment as it strongly correlates with cross-sectional area measures at the level of L3 and it allows a cost-effective body composition assessment without the need for additional radiation exposure.

Nutrition risk and mortality in older oncology patients: An exploratory study

AIM

The primary aim of this analysis was to identify if two standard measures incorporated into the comprehensive geriatric assessment; specifically, malnutrition risk and body mass index (BMI), could predict 12-month mortality in older patients with solid tumours. The secondary aim was to evaluate if malnutrition risk and BMI were associated with chemotherapy outcomes (discontinuation/modification of treatment) in older patients with solid tumours.

METHODS

Older patients (aged ≥70 years) with solid cancers were recruited from the outpatient oncology clinic of a tertiary hospital in Brisbane, Australia. Participants' nutritional parameters, BMI, and malnutrition risk (determined using the Malnutrition Screening Tool (MST)) were recorded at baseline. Mortality data and chemotherapy outcomes were recorded for 12 months.

RESULTS

Seventy-four participants (67% males, median age 77 (±4.4) years) were recruited. Nearly half the cohort was at-risk of malnutrition at baseline (n = 39, 46%). Chemotherapy was prescribed to 39% (n = 29) of the cohort. For patients receiving chemotherapy neither being underweight nor having a low or medium risk of malnutrition was associated with adverse chemotherapy outcomes or 12-month mortality. At a bivariate level, malnutrition risk was significantly associated with 12-month mortality in patients who did not receive chemotherapy (P = 0.018), but not BMI.

CONCLUSIONS

This analysis indicates that malnutrition risk was a potential indicator of 12-month mortality in cases where chemotherapy was considered unfeasible. However, this was not an independent risk factor. Further investigation using a larger sample is required to determine the association between malnutrition risk, quality of life and mortality in patients who are not considered to be fit for chemotherapy.

Benefits of Oral Nutritional Supplements in Patients with Locally Advanced Nasopharyngeal Cancer during Concurrent Chemoradiotherapy: An Exploratory Prospective Randomized Trial

BACKGROUND

Weight loss during chemoradiotherapy is a major problem in patients with head and neck cancer. The aim of this study was to evaluate the effect of ONS on weight, nutritional status and quality of life (QOL) in patients with loco-regionally advanced nasopharyngeal cancer (NPC) undergoing chemoradiotherapy.

METHODS

Patients with locally advanced NPC treated at a tertiary hospital in China prior to curative chemoradiotherapy were eligible for this exploratory randomized study. Patients were assigned to either the intervention or the control group based on a computer-generated randomization sequence. The intervention group commenced ONS at the start of chemoradiotherapy. Outcomes included body weight, BMI, nutritional status and QOL.

RESULTS

From June 2015 to June 2016, 50 patients with NPC were randomized to intervention and 50 to the control group. Patients in the ONS group had a higher body weight at the end of chemoradiotherapy (59.11 kg vs 58.14 kg, p = 0.036). A higher BMI and prealbumin were observed in the ONS group (p = 0.021 and p = 0.048, respectively). No other differences were found for nutritional status, QOL or clinical outcomes.

CONCLUSION

ONS had beneficial outcomes in terms of reducing weight loss, minimizing BMI decrease and increasing protein intake in loco-regionally advanced NPC patients during chemoradiotherapy.

Progressive resistance training in cachectic head and neck cancer patients undergoing radiotherapy: a randomized controlled pilot feasibility trial

BACKGROUND

Cancer cachexia is a prevalent symptom of head and neck neoplasms. The reduction in skeletal muscle mass is one of the main characteristics which can lead to poor physical functioning. The purposes of this pilot randomized controlled trial were to determine the feasibility of progressive resistance training in cachectic head and neck cancer patients during radiotherapy and to explore possible risks and benefits.

METHODS

Twenty cachectic participants with head and neck cancer receiving radiation were randomized to obtain either a machine supported progressive resistance training (n = 10) or usual care (n = 10). The training took place 3 times weekly for 30 min. Intervention included 3 exercises for major muscle groups with 8-12 repetition maximum for 3 sets each. Bioelectrical impedance analysis, hand-held dynamometry, Six-Minute Walk Test and standardized questionnaires for fatigue and quality of life were used for evaluating outcomes at baseline before radiotherapy (t1), after 7 weeks of radiotherapy (t2) and 8 weeks after the end of radiotherapy (t3).

RESULTS

All participants (n = 20) completed the trial. No serious adverse events occurred. At the initial assessment the cachectic patients had already lost 7.1 ± 5.2% of their body weight. General fatigue (score 10.7 ± 3.3) and reduced quality of life (score 71.3 ± 20.6) were prevalent in cachectic head and neck cancer patients even before radiotherapy. An average improvement of weight loading for leg press (+ 19.0%), chest press (+ 29.8%) and latissimus pull-down (+ 22.8%) was possible in the intervention group. Participants had at least 13 training sessions. The outcome measures showed nonsignificant changes at t2 and t3, but a trend for a better course of general fatigue and quality of life at t2 in the intervention group.

CONCLUSIONS

Despite advanced tumor stage and burdensome treatment the intervention adherence is excellent. Progressive resistance training in cachectic head and neck cancer patients during radiotherapy seems to be safe and feasible and may have beneficial effects of general fatigue and quality of life.

Protein calorie malnutrition, nutritional intervention and personalized cancer care

Cancer patients often experience weight loss caused by protein calorie malnutrition (PCM) during the course of the disease or treatment. PCM is expressed as severe if the patient has two or more of the following characteristics: obvious significant muscle wasting, loss of subcutaneous fat; nutritional intake of <50% of recommended intake for 2 weeks or more; bedridden or otherwise significantly reduced functional capacity; weight loss of >2% in 1 week, 5% in 1 month, or 7.5% in 3 months. Cancer anorexia-cachexia syndrome (CACS) is a multifactorial condition of advanced PCM associated with underlying illness (in this case cancer) and is characterized by loss of muscle with or without loss of fat mass. Cachexia is defined as weight loss of more than 5% of body weight in 12 months or less in the presence of chronic disease. Hence with a chronic illness on board even a small amount of weight loss can open the door to cachexia. These nutritional challenges can lead to severe morbidity and mortality in cancer patients. In the clinic, the application of personalized medicine and the ability to withstand the toxic effects of anti-cancer therapies can be optimized when the patient is in nutritional homeostasis and is free of anorexia and cachexia. Routine assessment of nutritional status and appropriate intervention are essential components of the effort to alleviate effects of malnutrition on quality of life and survival of patients.

An evaluation of nutrition intervention during radiation therapy in patients with locoregionally advanced nasopharyngeal carcinoma

Purpose

To evaluate the effectiveness of nutrition intervention during radiation for patients with locoregionally advanced (III-IVa) nasopharyngeal carcinoma (NPC).

Materials and Methods

We retrospectively reviewed 117 patients with locoregionally advanced (III-IVa) NPC treated between December 2015 and March 2016 in Zhejiang Cancer Hospital. All the patients underwent radical chemo-radiotherapy. First, all the patients were divided into the nutrition intervention group and the control group, depending on whether they accepted nutrition intervention. Repeated measures were used to analyze the change of nutritional indicators before, during, and after radiation therapy and to simultaneously compare the difference in nutritional status between the two groups at the same time point. Subsequently, the 117 patients were divided into the malnourished group (weight loss > 5%) and the non-malnourished group (weight loss ≤ 5%) according to whether their weight loss was over 5% of their body weight during radiotherapy. Chi-square tests and logistic regression analysis were used to explore the influence factors for the weight loss.

Results

The repeated measures showed that all indicators including weight, body mass index (BMI), albumin, pre-albumin(PA), and prognostic nutritional index (PNI) dramatically declined in both groups compared with their levels before radiation therapy (All p < 0.001). However, there was no significant difference between the intervention and non-intervention groups regarding the mean values of nutritional indicators at the same time point, that before, during, and after radiation therapy, except BMI (All p > 0.05). Logistic regression analysis revealed grade ≥ 3 radiation-induced oral mucositis as the prognostic factor for a poor nutrition status (odds ratio, OR = 3.232, p = 0.021, confidence interval, CI [1.198, 8.820]). Besides this, patients with a decrease of >15% in pre-albumin level were more likely to be malnourished (OR = 2.442, p = 0.041, CI [1.036, 5.757]). Similar to that observed in our former analysis, we did not find that existing nutrition intervention can significantly improve nutritional status (OR = 1.217, p = 0.704, CI [0.042, 3.348]).

Conclusions

Our study shows that the nutritional status of the patients gradually declined during treatment. We concluded that grade ≥ 3 radiation-induced oral mucositis would aggravate the extent of malnutrition during radiation therapy in patients with locoregionally advanced NPC. Pre-albumin level was a predictive marker for weight loss in patients with NPC. However, current nutrition intervention during radiation therapy can't significantly reverse nutritional status.

Nutritional changes in patients with locally advanced head and neck cancer during treatment

OBJECTIVE

The purpose of the study is to evaluate changes in body composition and nutritional status that occur throughout the oncological treatment in head and neck cancer patients.

METHODS

A prospective cohort observational study in patients diagnosed with head and neck squamous cell carcinoma (HNSCC) that underwent treatment with induction chemotherapy (iCT) followed by chemoradiotherapy or bioradiotherapy were invited to participate. All patients had dietetic counseling from the diagnosis and a close monitoring throughout the treatment implementing nutritional support as needed.

RESULTS

From June 2011 until October 2012, 20 patients were included. Nutritional and anthropometric parameters were collected at diagnosis, post iCT, after radiotherapy, 1 and 3months post radiotherapy. According to Patient Generated Subjective Global Assessment, 30% of patients were malnourished at diagnosis. After iCT there was an increase in weight, body mass index (BMI) and fat free mass (FFM) with almost complete improvement in dysphagia and odynophagia. Nevertheless a significant nutritional deterioration (p=0.0022) occurred at the end of radiotherapy with 95% of patients becoming severe or moderate malnourished. Nutritional parameters such as weight, BMI and hand grip strength also decrease significantly during treatment.

CONCLUSIONS

Despite an intensive nutritional support from the diagnosis throughout the oncological treatment in advanced HNSCC cancer patients, nutritional status deteriorates during radiotherapy. Our findings suggest that iCT may help improve nutritional status by ameliorating the symptoms that limit the oral intake. This improvement in the nutritional status could contribute to minimize further deterioration. Further investigations are needed involving novel approaches to avoid nutritional deterioration.

Randomised controlled trial of early prophylactic feeding vs standard care in patients with head and neck cancer

Background:

Weight loss remains significant in patients with head and neck cancer, despite prophylactic gastrostomy and intensive dietary counseling. The aim of this study was to improve outcomes utilising an early nutrition intervention.

Methods:

Patients with head and neck cancer at a tertiary hospital in Australia referred for prophylactic gastrostomy prior to curative intent treatment were eligible for this single centre randomised controlled trial. Exclusions included severe malnutrition or dysphagia. Patients were assigned following computer-generated randomisation sequence with allocation concealment to either intervention or standard care. The intervention group commenced supplementary tube feeding immediately following tube placement. Primary outcome measure was percentage weight loss at three months post treatment.

Results:

Recruitment completed June 2015 with 70 patients randomised to standard care (66 complete cases) and 61 to intervention (56 complete cases). Following intention-to-treat analysis, linear regression found no effect of the intervention on weight loss (10.9±6.6% standard care vs 10.8±5.6% intervention, P=0.930) and this remained non-significant on multivariable analysis (P=0.624). No other differences were found for quality of life or clinical outcomes. No serious adverse events were reported.

Conclusions:

The early intervention did not improve outcomes, but poor adherence to nutrition recommendations impacted on potential outcomes.

Supportive interventions for enhancing dietary intake in malnourished or nutritionally at-risk adults

BACKGROUND

Supportive interventions such as serving meals in a dining room environment or the use of assistants to feed patients are frequently recommended for the management of nutritionally vulnerable groups. Such interventions are included in many policy and guideline documents and have implications for staff time but may incur additional costs, yet there appears to be a lack of evidence for their efficacy.

OBJECTIVES

To assess the effects of supportive interventions for enhancing dietary intake in malnourished or nutritionally at-risk adults.

SEARCH METHODS

We identified publications from comprehensive searches of the Cochrane Library, MEDLINE, Embase, AMED, British Nursing Index, CINAHL, SCOPUS, ISI Web of Science databases, scrutiny of the reference lists of included trials and related systematic reviews and handsearching the abstracts of relevant meetings. The date of the last search for all databases was 31 March 2013. Additional searches of CENTRAL, MEDLINE, ClinicalTrials.gov and WHO ICTRP were undertaken to September 2016. The date of the last search for these databases was 14 September 2016.

SELECTION CRITERIA

Randomised controlled trials of supportive interventions given with the aim of enhancing dietary intake in nutritionally vulnerable adults compared with usual care.

DATA COLLECTION AND ANALYSIS

Three review authors and for the final search, the editor, selected trials from titles and abstracts and independently assessed eligibility of selected trials. Two review authors independently extracted data and assessed risk of bias, as well as evaluating overall quality of the evidence utilising the GRADE instrument, and then agreed as they entered data into the review. The likelihood of clinical heterogeneity amongst trials was judged to be high as trials were in populations with widely different clinical backgrounds, conducted in different healthcare settings and despite some grouping of similar interventions, involved interventions that varied considerably. We were only able, therefore, to conduct meta-analyses for the outcome measures, 'all-cause mortality', 'hospitalisation' and 'nutritional status (weight change)'.

MAIN RESULTS

Forty-one trials (10,681 participants) met the inclusion criteria. Trials were grouped according to similar interventions (changes to organisation of nutritional care (N = 13; 3456 participants), changes to the feeding environment (N = 5; 351 participants), modification of meal profile or pattern (N = 12; 649 participants), additional supplementation of meals (N = 10; 6022 participants) and home meal delivery systems (N = 1; 203 participants). Follow-up ranged from 'duration of hospital stay' to 12 months.The overall quality of evidence was moderate to very low, with the majority of trials judged to be at an unclear risk of bias in several risk of bias domains. The risk ratio (RR) for all-cause mortality was 0.78 (95% confidence interval (CI) 0.66 to 0.92); P = 0.004; 12 trials; 6683 participants; moderate-quality evidence. This translates into 26 (95% CI 9 to 41) fewer cases of death per 1000 participants in favour of supportive interventions. The RR for number of participants with any medical complication ranged from 1.42 in favour of control compared with 0.59 in favour of supportive interventions (very low-quality evidence). Only five trials (4451 participants) investigated health-related quality of life showing no substantial differences between intervention and comparator groups. Information on patient satisfaction was unreliable. The effects of supportive interventions versus comparators on hospitalisation showed a mean difference (MD) of -0.5 days (95% CI -2.6 to 1.6); P = 0.65; 5 trials; 667 participants; very low-quality evidence. Only three of 41 included trials (4108 participants; very low-quality evidence) reported on adverse events, describing intolerance to the supplement (diarrhoea, vomiting; 5/34 participants) and discontinuation of oral nutritional supplements because of refusal or dislike of taste (567/2017 participants). Meta-analysis across 17 trials with adequate data on weight change revealed an overall improvement in weight in favour of supportive interventions versus control: MD 0.6 kg (95% CI 0.21 to 1.02); 2024 participants; moderate-quality evidence. A total of 27 trials investigated nutritional intake with a majority of trials not finding marked differences in energy intake between intervention and comparator groups. Only three trials (1152 participants) reported some data on economic costs but did not use accepted health economic methods (very low-quality evidence).

AUTHORS' CONCLUSIONS

There is evidence of moderate to very low quality to suggest that supportive interventions to improve nutritional care results in minimal weight gain. Most of the evidence for the lower risk of all-cause mortality for supportive interventions comes from hospital-based trials and more research is needed to confirm this effect. There is very low-quality evidence regarding adverse effects; therefore whilst some of these interventions are advocated at a national level clinicians should recognise the lack of clear evidence to support their role. This review highlights the importance of assessing patient-important outcomes in future research.

Symptom management during and after treatment with concurrent chemoradiotherapy for oropharyngeal cancer: A review of the literature and areas for future research

Patients with locally advanced oropharyngeal cancer are at risk for poor outcomes due to the multi-modal nature of treatment and the potential for treatment-related toxicity. Although treatment with concurrent chemotherapy and radiotherapy has drastically reduced the need for a debilitating and disfiguring surgery, treatment related toxicities are often difficult to control. Acute toxicities include mucositis, skin desquamation, depression, cachexia, fatigue and nausea and vomiting. Failure to control these symptoms can adversely affect the patient’s ability to complete their treatment regimen. Although there are many promising new treatments in the area of symptom management for this patient population, a review of the literature reflects the need for more research.

The effects of patient participation-based dietary intervention on nutritional and functional status for patients with gastrectomy: a randomized controlled trial

BACKGROUND

Patients undergoing gastrectomy because of stomach cancer often face weight loss in the perioperational period, which can lead to malnutrition and negative treatment outcomes.

OBJECTIVE

The purpose of this study was to develop a patient participation-based dietary intervention (PPDI) and evaluate its effects on patient outcomes.

INTERVENTIONS/METHODS

This was a prospective, randomized controlled trial in which the patients were recruited in a cancer center in South Korea. The participants (N = 56), who underwent gastrectomy with stomach cancer stage I to III, were randomly assigned into either the experimental or the control group. The PPDI, which was given on the day before the hospital discharge, comprised 2 face-to-face and 2 telephone interventions. The outcome variables included body weight, body mass index, muscle mass, the Patient-Generated Subjective Global Assessment, Dietary Symptom Scale, Functional Assessment Cancer Therapy-General, Karnofsky Performance Status, Adherence to Dietary Guidelines Scale, Scale of Dietary Knowledge, Patient Satisfaction Scale, and a 3-day food diary.

RESULTS

Participants in the PPDI intervention demonstrated significant (P < .05) reductions in adverse dietary symptoms and significant improvements (P < .05) in functional status, performance status, dietary intake, adherence to dietary guidelines, dietary knowledge, and satisfaction with the intervention as compared with the control group over time.

CONCLUSION

The PPDI was an effective dietary intervention for patients undergoing a gastrectomy for gastric cancer and deserves additional study in other populations of patients.

IMPLICATIONS FOR PRACTICE

Incorporating patients' perspectives into a dietary intervention after gastrectomy for gastric cancer may contribute to improved patient outcomes and quality care.

Outcomes of systematic nutritional assessment and medical nutrition therapy in pancreatic cancer

OBJECTIVES

We investigated the nutritional and survival outcomes of medical nutrition therapy by a registered dietitian, along with support from a dedicated nutrition and metabolic support team in pancreatic cancer patients requiring enteral or parenteral nutrition.

METHODS

Subjective global assessment (SGA) was used to assess nutritional status in 304 pancreatic cancer patients. Using baseline and last SGA, patients were categorized into 3 groups: improved SGA, deteriorated SGA, and unchanged SGA. Kaplan-Meier and Cox regression were used to calculate survival after controlling for relevant confounders.

RESULTS

One-hundred twenty-five (41.1%) patients had their SGA unchanged, 87 (28.6%) patients had "improved SGA," whereas 92 (30.3%) patients had "deteriorated SGA." On univariate survival analysis, the median survival was 7.8, 11.2, and 12.6 months for deteriorated, unchanged, and improved SGA groups, respectively. On multivariate analysis, change in SGA was independently predictive of survival. Patients with deteriorated SGA had 1.5 times (95% confidence interval, 1.1-2.1) greater risk of mortality compared to those with improved SGA.

CONCLUSIONS

The majority of pancreatic cancer patients (70%) in our study either maintained or improved their nutritional status during cancer treatment. Improvement in SGA correlated with a significantly decreased risk of mortality independent of sex, previous treatment history, and evidence of biological anticancer activity.

Availability of Outpatient Clinical Nutrition Services for Patients With Cancer Undergoing Treatment at Comprehensive Cancer Centers

Comprehensive cancer centers rely on referral-based clinical nutrition services, which are not always a part of multidisciplinary care. An in-depth comparison of clinical nutrition services among other approaches to cancer care is needed.

Patient satisfaction is rated higher by radiation oncology outpatients receiving nutrition intervention compared with usual care

BACKGROUND

Satisfaction with services has been considered vital for the provision of quality health care, however, there are few published papers utilizing patient satisfaction with nutrition services as a measurable outcome.

METHOD

A randomized, controlled trial investigating the impact of nutrition intervention (NI) vs. usual care (UC) in 54 ambulatory oncology patients receiving radiotherapy to the gastrointestinal or head and neck area demonstrated beneficial impacts in terms of body weight, nutritional status, quality of life and bowel health. This study reports the changes in patient satisfaction that were associated with these improved outcomes for patients receiving NI compared with UC. The patient satisfaction with clinical nutrition services questionnaire was used to measure overall satisfaction and satisfaction with four components of nutrition services 12 weeks after patients commenced radiotherapy.

RESULTS

Patients receiving NI rated satisfaction higher for staff interpersonal skills (P < 0.001), perceived health benefits (P = 0.008), staff presentation skills (P = 0.044) and for overall patient satisfaction with nutrition services (P = 0.002). There were no significant differences between those patients receiving NI or UC for the nutrition supplements factor (P = 0.191).

CONCLUSIONS

These data suggest that patients receiving NI perceive nutrition as being beneficial and of higher importance to their health than those receiving UC. This may lead to increased compliance with the nutrition prescription and help explain the better outcomes observed in the NI group compared with the UC group. Patient satisfaction with nutrition services should be conducted regularly to act as a quality-control measure and target areas for improvement.
