The Role of Nutritional Support for Cancer Patients in Palliative Care

The Importance of Nutrition in Cancer Care: A Narrative Review

PURPOSE OF REVIEW

Cancer, a complex disease affecting millions globally, presents considerable challenges for both patients and health care providers. Within the broad spectrum of cancer care, nutrition plays a key role in supporting patients throughout their journey. This narrative review examines the role of nutrition in cancer care, exploring its impact on treatment outcomes, nutritional status, current dietary recommendations, physical activity, palliative care, and finally, as a nutritional encouragement for cancer survivors.

RECENT FINDINGS

Evidence indicates that cancer and anticancer treatments frequently cause malnutrition and loss of muscle mass, which can exacerbate symptoms, impair immune function, and hamper recovery. Therefore, adequate nutritional support is crucial for maintaining strength, controlling symptoms, and optimizing treatment tolerance in patients with cancer. Several factors influence nutritional needs and dietary recommendations, including cancer type, treatment, and individual patient characteristics. Nutritional care aims not only to ensure sufficient energy and protein intake, but also to manage specific symptoms such as dysgeusia, nausea, and dysphagia. Registered dietitians play a crucial role in providing personalized nutritional guidance, monitoring nutritional status, and implementing interventions to address emerging challenges in cancer care. Furthermore, recent research has underscored the benefits of dietary interventions in cancer treatment. From targeted nutritional supplements to more invasive nutritional support, interest in how nutrition can affect cancer risk and treatment outcomes is increasing. Overall, this review highlights the critical role of nutritional care in comprehensive cancer treatment. By recognizing and meeting dietary demands throughout the entire cancer journey, health care professionals can improve patients' well-being, response to treatment, and long-term prognosis.

Perioperative use of enteral nutrition with ω-3 polyunsaturated fatty acid in patients with gastric cancer: a meta-analysis

Objectives

To systematically evaluate the efficacy and safety of enteral nutrition with ω-3 polyunsaturated fatty acid preparations or standard enteral nutrition preparations used in patients with gastric cancer during perioperative period, and to provide reference for clinical rational drug use.

Methods

Pubmed, EMbase, The Cochrane Library, CNKI and Wanfang Medical databases were searched by computer to collect relevant literature. The search period was from the establishment of the database to August 1, 2024. Meta-analysis was performed using Revman5.4 software after two researchers independently screened literature, extracted data, and evaluated the risk of bias in included studies.

Results

A total of 20 randomized controlled studies were included. The Meta results showed that there was no statistical difference in mortality between the enteral nutrition with ω-3 polyunsaturated fatty acid group and the control group (RR = 0.46, P = 0.17). However, the IEN group demonstrated superior advantages in reducing infection complications (RR = 0.81, P = 0.05) and wound infection (RR = 0.61, P = 0.04) among gastric cancer patients, as well as improving immune-related indicators (including IgG, IgA, IgM, CD4, and CD4/CD8), inflammation-related markers (including CRP, IL-1β, and IL-6), and nutritional indicators (including Total protein, Albumin, and Transferrin).

Conclusion

enteral nutrition with ω-3 polyunsaturated fatty acid preparation has advantages in the efficacy and safety of perioperative nutritional therapy in patients with gastric cancer, and can be used as a clinical choice. Due to the limited number and quality of included studies, the above conclusions need to be verified by more high-quality studies.

Effectiveness of prognostic nutritional index in predicting overall survival and evaluating immunotherapy response in anaplastic thyroid carcinoma

BACKGROUND

The prognostic value of nutritional status in anaplastic thyroid carcinoma (ATC) remains unclear. The Prognostic Nutritional Index (PNI) is a reliable indicator of overall nutritional and immune status, and it has emerged as a significant prognostic factor in various malignancies. This study aimed to explore the utility of PNI in ATC.

METHODS

We systematically reviewed ATC patients in our institute from January 2000 to June 2023 and categorized them into high and low PNI groups based on the median PNI value. Kaplan-Meier analysis and Cox regression were employed to assess the impact of PNI on overall survival, while ROC curve analysis evaluated the predictive value of PNI. Mimics software was used for three-dimensional reconstruction of pre- and post-immunotherapy tumor volumes, enabling the assessment of treatment response.

RESULTS

A total of 77 ATC patients were included in this study. Low baseline PNI was associated with significantly shorter overall survival (1-year survival rate: 5.26% vs 30.77%; median survival time: 5.30 months vs 8.87 months). The 1-year, 2-year, and 3-year AUC values for PNI were 0.82, 0.79, and 0.77, respectively. In the multivariate analysis, both PNI and tumor size emerged as independent prognostic factors for patient overall survival. Among ATC patients receiving 2-3 cycles of immunotherapy, an increase in post-treatment PNI levels was positively correlated with a reduction in tumor volume.

CONCLUSION

PNI is an independent predictor of overall survival and holds the potential to serve as a valuable indicator for assessing and predicting immunotherapy efficacy in ATC patients.

Malnutrition is Associated With Fatigue and Anxiety in Advanced Cancer Patients Admitted to Home Palliative Care

OBJECTIVE

Information regarding the nutrition profile of advanced cancer patients followed at home is lacking. The aim of this study was to assess the nutritional status of patients who were admitted to specialized home palliative care, and examine eventual factors associated with malnutrition.

DESIGN

Cross-sectional. Setting/subject: patients who were admitted to 2 specialized home palliative care programs.

PARTICIPANTS

A consecutive sample of patients admitted to home care was selected. Depression, anxiety, nausea, poor appetite, and poor well-being were measured by numerical scale 0-10. Mini nutritional assessment form (MNA-SF), fatigue assessment scale (FAS), and sarcopenia by SARC-F. were performed. The use of drugs used for anorexia, including corticosteroids, progestins, or others, was recorded.

RESULTS

Data of 135 patients were analyzed. Sixty-eight per cent and 77% of patients resulted to be malnourished and sarcopenic. In the multivariate regression analysis, anxiety (P = 0.036) and total FAS (P = 0.013) were independently associated with malnutrition. Fifty-five per cent of patients were receiving corticosteroids or megestol acetate. No significant associations with parameters examined were found.

CONCLUSION

The majority of advanced cancer patients admitted to home palliative care were malnourished independently of the primary tumor diagnosis. Indeed, fatigue and anxiety were independently associated with malnutrition.

Comparison of nasojejunal nutrition and intravenous nutrition supplementation in patients with upper gastrointestinal tract strictures and analysis of risk factors for malnutrition

This study examines the effectiveness of nasojejunal and intravenous nutrition in supplementing nutrition for patients with upper gastrointestinal (GI) strictures and analyzes the risk factors associated with malnutrition to provide references for clinical nutrition strategies. A retrospective analysis was conducted on 71 patients with upper GI strictures caused by esophageal and gastric cancers, who received nutritional support from January 2015 to January 2023. Out of these, 53 patients had complete baseline and follow-up data. We collected general clinical and perioperative data for comparison of the efficacy between nasojejunal nutrition and intravenous nutrition. Risk factors for malnutrition were analyzed using univariate and multivariate logistic regression. Malnutrition occurred in 24.53% (13/53) of the patients with upper GI strictures. The incidence of malnutrition was 6.06% (2/33) in the nasojejunal nutrition group compared to 55.00% (11/20) in the intravenous nutrition group, with a statistically significant difference (P < .001). Univariate and multivariate regression analyses identified diabetes (P < .001), initial blood K (P = .011), pathological staging (P < .001), and pathological grading (P < .001) as risk factors for malnutrition in patients with upper GI strictures. Diabetes (P = .028), initial blood K (P = .018), and pathological staging (P = .011) were found to be independent risk factors. Nasojejunal nutrition results in a lower incidence of malnutrition compared to intravenous nutrition in patients with upper GI strictures. Diabetes, initial blood K, pathological staging, and pathological grading are risk factors for malnutrition, with diabetes, initial blood K, and pathological staging serving as independent risk factors.

Necessity and influencing factors for integrating oral health in cancer care for older people: a narrative review

PURPOSE

The number of older people with poor oral health diagnosed with cancer is increasing rapidly. However, integration of oral health in cancer care for older people to prevent or minimize oral health complications of cancer treatments is uncommon, except in head and neck oncology. The aim of this review is to describe the need, role of, and factors influencing the integration of oral health(care) into the treatment of older people with cancer.

METHODS

MEDLINE, CINAHL, PubMed, Scopus, and Web of Science databases were searched for papers published in the last 10 years that focus on oral health in older people diagnosed with cancer, the impact of oral health on cancer therapy, and integrated oral health in cancer treatment.

RESULTS

From 523 related papers, 68 publications were included and summarized as follows: (1) oral complications associated with cancer therapies, (2) the need for oral healthcare in older people with cancer, (3) the role of integration of oral health in cancer care, and (4) influencing factors such as ageism, interprofessional education and collaborations, oral healthcare workforce, oral health literacy, and financial considerations.

CONCLUSION

Integration of oral healthcare is highly recommended for the overall well-being of older people with cancer to prevent, minimize, and manage complications in cancer treatment. However, oral healthcare has not been integrated in cancer care yet, except for head and neck cancers. This review identified a notable gap in the literature, highlighting the need for research on integration of oral healthcare in geriatric oncology.

The role of food during oncology treatment: perspectives of cancer patients, caregivers and healthcare professionals

PURPOSE

Many cancer patients have problems eating which are usually connected to taste and smell alterations due to side effects of cancer treatment. These problems have consequences both in terms of malnutrition and reduced quality of life. In order to explore social and psychological consequences of eating problems in cancer patients, qualitative interviews were conducted with cancer patients, their caregivers and healthcare professionals.

METHODS

The study was conducted in three European countries (Poland, Spain and the UK) that differed in culture, oncology care approaches and availability of nutritional products targeted to cancer patients in the market.

RESULTS

Differences in the social role of eating between the three European countries were observed which subsequently influenced the impact of eating problems for cancer patients in these countries. Furthermore, the study found that problems with food affect not only the quality of life of cancer patients, but can also distress their caregivers, who are often unable to cope with such food-related problems. In addition, the study showed that commercially available nutritional products for cancer patients focus on nutritional value but tend to neglect an important aspect of eating, which is the enjoyment of food, both individually and socially.

Supplemental tube feeding: qualitative study of patient perspectives in advanced pancreatic cancer

OBJECTIVES

Malnutrition is associated with poor quality of life and survival outcomes for patients with cancer, but is challenging to prevent or treat in pancreatic cancer due to the multifactorial drivers of nutritional decline. A novel application of percutaneous endoscopic gastrostomy with a jejunal extension tube to deliver supplementary nutrition may improve outcomes, and will be tested in a randomised controlled trial. This study explored the perspectives of people living with pancreatic cancer regarding the acceptability of this proposed intensive nutrition intervention, to elucidate appropriateness and anticipated barriers, and facilitate informed design of the planned trial.

METHODS

Participants were patients with pancreatic cancer previously enrolled in a Pancreaticobiliary Cancer Biobank. Qualitative semi-structured interviews were conducted by telephone and transcribed verbatim for deductive thematic analysis. The Framework Model was used, with the Theoretical Framework of Acceptability as the analytical framework.

RESULTS

10 participants were recruited. Four overarching themes were developed from interviews: (1) deterioration in physical and mental well-being are consequences of debilitating nutrition impact symptoms; (2) willingness to participate depends on an individual threshold for nutritional deterioration; (3) predicted perceived effectiveness outweighed anticipated burdens and (4) adequate dietetic support is needed for maintaining a percutaneous endoscopic gastrostomy with jejunal extension feeding tube at home with confidence.

CONCLUSIONS

Most participants believed that the intervention would benefit people with advanced pancreatic cancer to maintain their nutrition throughout chemotherapy. Regular and ad hoc support was considered essential, and the degree of individual nutritional deterioration was identified as an important indicator for trial participation.

Association of plant-based dietary patterns with depression and anxiety symptoms in Chinese older adults: A nationwide study

BACKGROUND

The associations of plant-based dietary patterns with depression and anxiety symptoms among older adults have not been extensively studied. Therefore, the purpose of this study was to examine these associations in Chinese older adults.

METHODS

Data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) was employed in the present study. The simplified food frequency questionnaire was used to assess the overall plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI). The Center for Epidemiologic Studies Depression Scale-10 (CES-D-10) was used to evaluate depression symptoms, and the Generalized Anxiety Disorder Scale-7 (GAD-7) was used to assess anxiety symptoms. This study employed logistic regression and linear regression to examine the associations between plant-based dietary patterns and symptoms of depression and anxiety.

RESULTS

This study included 11,971 older adults, with a mean age of 83.23 ± 11.10 years. The results indicated that PDI and hPDI were negative associated with depression symptoms (adjusted β -0.09, 95 % CI -0.11, -0.07) (adjusted β -0.09, 95 % CI -0.11, -0.07) and anxiety symptoms (adjusted β -0.03, 95 % CI -0.04, -0.02) (adjusted β -0.04, 95 % CI -0.05, -0.02), while uPDI was positive associated with depression symptoms (adjusted β 0.09, 95 % CI 0.07, 0.11) and anxiety symptoms (adjusted β 0.04, 95 % CI 0.03, 0.05).

CONCLUSIONS

The findings from this study have the potential to promote healthy dietary patterns in older adults, and may have implications for the prevention and management of depression and anxiety in this population.

Proposal of a nutrition screening algorithm for patients with incurable cancer receiving palliative care: Data from a prospective cohort

OBJECTIVE

To propose and evaluate the clinical utility of a new nutrition screening algorithm, NutriPal, to detect the degree of nutritional risk in patients with incurable cancer receiving palliative care.

METHODS

It is a prospective cohort conducted in an oncology palliative care unit. The NutriPal algorithm was used in a three-step process: (i) administration of the Patient-Generated Subjective Global Assessment short form; (ii) calculation of the Glasgow Prognostic Score; and (iii) application of the algorithm to classify patients into four degrees of nutritional risk. The higher the degrees of NutriPal, the worse the nutritional risk, comparing nutritional measures, laboratory data, and overall survival (OS).

RESULTS

The study included 451 patients that were classified using the NutriPal. They were allocated to the degrees: 1 (31.26%), 2 (27.49%), 3 (21.73%), and 4 (19.71%). Statistically significant differences were found in most of the nutritional and laboratory parameters and in OS with each increment in the NutriPal degrees, and OS was reduced (log-rank <0.001). In addition, NutriPal was able to predict a 120-day mortality: there was a significantly higher risk of death in the patients classified as degrees 4 (hazard ratio [HR], 3.03; 95% confidence interval [95% CI], 2.18-4.19), 3 (HR, 2.01; 95% CI, 1.46-2.78), and 2 (HR, 1.42; 95% CI; 1.04-1.95) than in those classified as degree 1. It also showed good predictive accuracy (concordance statistic, 0.76).

CONCLUSION

The NutriPal is associated to nutritional and laboratory parameters and can predict survival. It could therefore be incorporated into clinical practice for patients with incurable cancer receiving palliative care.

Chemotherapy alone versus chemotherapy plus 125I brachytherapy for the second-line treatment of locally recurrent cervical cancer after/with radical treatment: A propensity score analysis

Rationale and objectives

The primary aim of this study was to conduct a retrospective comparative analysis of the survival outcomes in patients with recurrent cervical cancer (CC). Specifically, we aimed to compare the efficacy of chemotherapy alone versus the combined approach of chemotherapy and 125I brachytherapy subsequent to the failure of initial chemotherapy treatment.

Materials and methods

Patients diagnosed with recurrent CC subsequent to the failure of initial chemotherapy from January 2007 to December 2016 were enrolled from 2 hospitals. These patients were then divided into two groups: Group A, which underwent second-line chemotherapy alone, and Group B, which received both second-line chemotherapy and 125I brachytherapy. The assessment of overall survival (OS) and progression-free survival (PFS) was carried out through propensity score matching (PSM) (1:1), Kaplan-Meier curves, log-rank tests, and Cox proportional hazard regression for survival analysis.

Results

A matched cohort comprising 88 patients each in Group A and Group B was included in the study. In Group A, the 1-, 2-, and 3-year cumulative PFS rates were 40.9 %, 15.9 %, and 5.7 % respectively, while in Group B, these rates were significantly higher at 79.5 %, 48.9 %, and 25.0 % (P = 0.003). Similarly, the 1-, 2-, and 3-year cumulative OS rates among Group A were 67.0 %, 27.3 %, and 5.7 % compared to 89.8 %, 63.6 %, and 30.7 % among Group B, suggesting a difference with statistical significance (P < 0.001) between the two groups. Moreover, the incidence of complications was similar between groups (P = 0.698).

Conclusions

Our findings suggest that the combined approach of chemotherapy and 125I brachytherapy yields superior therapeutic effects but similar complication rates compared to chemotherapy alone in patients experiencing local recurrence of CC following failed initial chemotherapy.

On the Discontinuation of Enteral Feeding in Head and Neck Cancer: A Case Report

Introduction

The goal of palliative care is to preserve the quality of life or patient "comfort" in patients with serious diseases. Palliative care providers serve a wide range of patients: from those who seek curative treatment to those who are actively dying. Given this range, palliative care must mirror the dynamic goals of the patient at different stages of life and treatment. Throughout these stages, a goal of the palliative care provider would be to avoid hastening death; however, this often leads to clinical decisions that directly pit the patient's comfort against the patient's life span. This is most salient with clinical decisions of withdrawing treatments that prolong life even at the expense of comfort. An example of this dichotomy can be seen when providers use enteral nutrition to treat head and neck cancer patients.

Case Presentation

We describe a patient with stage IV pancreatic cancer with metastases to her head and neck. The patient was experiencing increased morbidity related to her percutaneous endoscopic gastrostomy (PEG) tube feeding. These complications included tube-related concerns such as infection, leakage, and diarrhea but also decreased intended benefits as she lost weight and functionality while maintaining enteral feeding. Despite the patient experiencing a common and expected disease course, she remained unsure and was fearful about considering discontinuation of her enteral feeding. However, the care team who understood the risks, benefits, and harms related to withdrawal provided a foundation of discussion and mitigated patient fears, allowing for the successful removal of her PEG tube and increased quality of life at the end of life.

Conclusion

To care for a patient in their entirety is also to care for them at all stages of disease. Care is not limited to those who might be cured of disease, but should also consider those who continue to live with disease and the downstream effects of medical interventions used to support them. Discontinuing treatments whose harms outweigh the benefits to patients is a moral imperative to providers; yet, how providers approach discontinuing life-prolonging treatment is seen as morally distressing. Our patient did not see the discussion as morally distressing and continued to benefit from active discussions even at the end of her life.

Sipping as a Nutritional Supplement in Ambulatory Palliative Oncology Care: A Pilot Study with Noninvasive Methods

Objective: The implementation of nutritional support is a basic need of patients in palliative oncological care. This pilot study optimized the use of sipping to improve the nutritional status of cancer patients in palliative care. Materials and Method: The pilot study included 63 patients, 61.3 years of age on average (range: 32-82 years of age). The patients were assigned to either group A (no nutritional support n = 39 patients) or group B (sipping as nutritional support n = 24 patients). The patients were evaluated through by noninvasive methods: body weight, waist and arm circumference, and triceps skinfold, bioimpedance analysis, and dynamometry. Quality of life was assessed through modified questionnaires. Results: In contrast with group A, group B did not have a significant weight loss, that is, A: 81.9 ± 15.8-80.5 ± 15.8 kg (P = .028) and B: 73.9 ± 14.9-73 ± 16 kg. Body mass index A: 29 ± 5-28.5 ± 5 kg/m2 (P = .007) and B: 25.3 ± 4.7-25 ± 4.9 kg/m2 (P = .614). Waist circumference A: 93.5 ± 15.1-92.5 ± 14.8 cm (P = .008) and B: 80.1 ± 13.2-80.6 ± 12.3 cm (P = .234). Triceps skinfold A: 12.3 ± 7.2-11 ± 6.7 mm (P = .001) and B: 8.2 ± 6.1-7.9 ± 5.7 mm (P = .207). Fat free mass A: 54.8 ± 11.5-52.8 ± 11.6 kg (P = .018) and B: 54.7 ± 10.9-52.8 ± 11.5 kg (P = .207). Significantly lower dynamometer values were recorded in both groups; A: 25.6 ± 10.4-23.1 ± 10.3 kg (P = .010) and B: 27.4 ± 9.9-24.3 ± 9.1 kg (P = .009). In contrast to group B, the patients in group A showed slight variations in their health status, thus decreasing their scores into the significance limit (P = .072). Conclusion: Our results suggest that providing nutritional support in the form of sipping (∼12 g proteins, 300 kcal) on a daily basis prevents the loss of active tissue mass in palliative oncology patients. Based on these results, we recommend the inclusion of this simple nutritional support to prevent malnutrition in cancer patients in palliative care. The clinical study was registered by the internal ethics committee under the heading of its approval - Institutional Ethics Committee of the Hradec Králové Faculty Hospital, number 201311S2OP.

Routine laboratory parameters to support decision on parenteral nutrition in palliative care

Introduction

Parenteral nutrition (PN) is widely used in palliative care (PC), but there is limited evidence to support its use at the end of life (EOL). This aim of this was to investigate the relationship between routine laboratory parameters and survival in patients receiving PN, and to develop a decision tree model to support clinicians decide whether to start or forgo PN.

Methods

The laboratory parameters of 113 patients with advanced diseases who were admitted to a specialized palliative care unit (PCU) were analyzed at two points in time: T0 = before PN, T1 = two weeks after initiation of PN. Univariate Mann-Whitney U-tests and multivariate linear regression models, as well as a decision tree analysis were computed; all in relation to survival time.

Results

The final regression model was significant with p = 0.001 (adjusted R2 = 0.15) and included two predictors for survival time after PN initiation: the CRP/albumin ratio and urea at T1 (ps = 0.019). Decision tree analysis revealed three important predictors for classification of survival time after PN initiation: CRP, urea, and LDH (all at T0).

Discussion

The decision tree model may help to identify patients likely to benefit from PN, thus supporting the clinical decision whether or not to start PN.

Nutritional support in palliative cancer care: quality of life in oral versus tube feeding

BACKGROUND

Nutritional support (NS) offered through oral nutritional supplements (ONS) or enteral nutrition (EN) and its impact on quality of life (QoL) is a controversial topic in patients with cancer receiving palliative care (PC).

AIMS

To compare the QoL of patients without and with use of NS, including ONS or EN in patients with incurable cancer receiving PC.

METHODS

Cross-sectional analysis with patients that were evaluated at PC Unit between June 2021 and February 2023. QoL was assessed using the Quality of Life Questionnaire Core 15. Patients were classified into three groups according to the NS: ONS (n=72; 33%), EN (n=61; 28%) and control group (CG) (n=87; 39%), the last one being formed by patients not using NS. Adjusted logistic regression models were used to verify the association of the domains of QoL with the type of NS.

RESULTS

A total of 220 patients were included, with a median age of 64 (58-70) years, predominantly male (54.1%). The EN group had worse scores in physical function when compared with the ONS group (p=0.037) and appetite loss when compared with the CG (p=0.013). The ONS (OR: 2.70; 95% CI 1.32 to 5.49) and EN groups (OR: 2.61; 95% CI 1.24 to 5.49) were independently associated with a higher chance of presenting appetite loss in relation to the CG.

CONCLUSION

In general, there was no difference in the QoL of patients using NS when compared with patients not using NS. However, patients using NS have more chance of having appetite loss.

CONUT can be a predictor of postoperative complications after laparoscopic-assisted radical gastrectomy for elderly gastric cancer patients

Compared with young patients, elderly patients with gastric cancer usually have lower muscle mass, poorer nutritional status, lower immunity, and worse cardiopulmonary function. Therefore, how to improve the prognosis of elderly gastric cancer patients after laparoscopic-assisted radical gastrectomy is the focus and difficulty of clinician. The aim of our study was to investigate the risk factors for postoperative complications of these patients. The data of gastric cancer patients aged ≥ 60 years who underwent laparoscopic-assisted radical gastrectomy were analyzed. Univariate was used to determine the potential risk factors and then multivariate analyses was used to determine the independent risk factors for postoperative complications. Univariate analysis showed that age, preoperative red blood cell (RBC), preoperative albumin (ALB), preoperative C-reactive protein (CRP), preoperative hemoglobin (Hb), preoperative blood transfusion, preoperative lymphocytes, total cholesterol, CRP-to-ALB ratio, controlling nutritional status (CONUT) score, TNM stage were all the potential risk factors for postoperative complications. Binary logistic regression showed that CONUT, age and preoperative RBC were correlated with postoperative complications. For elderly gastric cancer patients after laparoscopic-assisted radical gastrectomy, CONUT, age and preoperative RBC were all the independent risk factors for overall postoperative complications and could be used as reliable indicators for judging the short-term prognosis.

Clinical usefulness of the Patient-Generated Subjective Global Assessment and modified Glasgow Prognostic Score in decision making concerning the indication of enteral nutritional therapy in patients with incurable cancer receiving palliative care

OBJECTIVES

This study aimed to identify the clinical usefulness of assessing nutritional status using validated tools for the indication of enteral nutrition for patients with incurable cancer in palliative care.

METHODS

In this prospective cohort study, patients were assessed for nutritional risk using the Patient-Generated Subjective Global Assessment and for cancer cachexia (CC) using the modified Glasgow Prognostic Score upon enrollment and after ∼30 d. The outcome was stable or improved Karnofsky Performance Status. Logistic regression models were used, providing the odds ratio (OR) and 95% confidence interval (CI).

RESULTS

A total of 180 patients participated. The only nutritional status parameter that was associated with function was CC. The less severe the CC, the more likely Karnofsky Performance Status was to remain stable or improve over 30 d (non-cachectic: OR = 1.95; 95% CI, 1.01-3.47; malnourished: OR = 1.06; 95% CI, 1.01-1.42). Furthermore, white skin color (OR = 1.79; 95% CI, 1.04-2.47), higher educational level (OR = 1.39; 95% CI, 1.13-2.78), and inadequate calorie intake (OR = 1.96; 95% CI, 1.02-2.81) were also associated with the outcome.

CONCLUSIONS

Using the modified Glasgow Prognostic Score to identify the existence and severity of CC, which is associated with function, has the potential to help clinical decision making concerning the indication of enteral nutrition in patients with incurable cancer receiving palliative care.

Nutritional counseling for patients with incurable cancer: Systematic review and meta-analysis

BACKGROUND & AIMS

This systematic review aims to determine whether nutritional counseling by registered dietitians and/or nutritional specialists is recommended for adult patients with incurable advanced or recurrent cancer who are refractory to or intolerant of anticancer therapy.

METHODS

This systematic review analyzed randomized controlled trials (RCTs) of nutritional counseling in cancer patients older than 18 years, primarily those with stage 4 cancer. Nutrition counseling was performed by registered dietitians and/or nutritional specialists using any method, including group sessions, telephone consultations, written materials, and web-based approaches. We searched the Medline (PubMed), Medline (OVID), EMBASE (OVID), CENTRAL, Emcare, and Web of Science Core Collection databases for articles published from 1981 to 2020. Two independent authors assessed the risk of bias used the Cochrane Risk of Bias 2 tool. Meta-analysis was performed for results and outcomes that allowed quantitative integration. This systematic review protocol was registered with the International Prospective Register of Systematic Reviews (ID: CRD42021288476) and registered in 2021.

RESULTS

The search yielded 2376 studies, of which 7 assessed 924 patients with cancer aged 24-95 years. Our primary outcome of quality of life (QoL) was reported in 6 studies, 2 of which showed improvement with nutritional counseling. Our other primary outcome of physical symptoms was reported in two studies, one of which showed improvement with nutritional counseling. Quantitative integration of both QoL and physical symptoms was difficult. A meta-analysis of energy and protein intake and body weight was performed for secondary outcomes. Results showed that nutrition counseling increased energy and protein intake, but total certainty of evidence (CE) was low. Bodyweight was not improved by nutrition counseling.

CONCLUSIONS

Nutrition counseling is shown to improve energy and protein intake in patients with incurable cancer. Although neither nutrient intake can be strongly recommended because of low CE, nutrition counseling is a noninvasive treatment strategy that should be introduced early for nutrition intervention for patients with cancer. This review did not find sufficient evidence for the effect of nutrition counseling on QoL, a patient-reported outcome. Overall, low-quality and limited evidence was identified regarding the impact of nutrition counseling for patients with cancer, and further research is needed.

Advanced Adrenocortical Carcinoma: From Symptoms Control to Palliative Care

The prognosis of patients with advanced adrenocortical carcinoma (ACC) is often poor: in the case of metastatic disease, five-year survival is reduced. Advanced disease is not a non-curable disease and, in referral centers, the multidisciplinary approach is the standard of care: if a shared decision regarding several treatments is available, including the correct timing for the performance of each one, overall survival is increased. However, many patients with advanced ACC experience severe psychological and physical symptoms secondary to the disease and the cancer treatments. These symptoms, combined with existential issues, debase the quality of the remaining life. Recent strong evidence from cancer research supports the early integration of palliative care principles and skills into the advanced cancer patient's trajectory, even when asymptomatic. A patient with ACC risks quickly suffering from symptoms/effects alongside the disease; therefore, early palliative care, in some cases concurrent with oncological treatment (simultaneous care), is suggested. The aims of this paper are to review current, advanced ACC approaches, highlight appropriate forms of ACC symptom management and suggest when and how palliative care can be incorporated into the ACC standard of care.

Home Artificial Nutrition and Energy Balance in Cancer Patients: Nutritional and Clinical Outcomes

Malnutrition is one of the main factors determining cachexia syndrome, which negatively impacts the quality of life and survival. In cancer patients, artificial nutrition is considered as an appropriate therapy when the impossibility of an adequate oral intake worsened nutritional and clinical conditions. This study aims to verify, in a home palliative care setting for cancer patients, if home artificial nutrition (HAN) supplies a patient’s energy requirement, improving nutritional and performance status. A nutritional service team performed counseling at a patient’s home and assessed nutritional status (body mass index, weight loss in the past 6 months), resting energy expenditure (REE), and oral food intake; Karnofsky Performance Status (KPS); cachexia degree; and survival. From 1990 to 2021, 1063 patients started HAN. Among these patients, 101 suspended artificial nutrition for oral refeeding. Among the 962 patients continuing HAN until death, 226 patients (23.5%) survived 6 weeks or less. HAN allowed to achieve a positive energy balance in 736 patients who survived more than 6 weeks, improving body weight and KPS when evaluated after 1 month of HAN. Advanced cancer and cachexia degree at the entry of the study negatively affected the positive impact of HAN.

Effects of specialised nutritional interventions in patients with incurable cancer: a systematic review

Objective

To evaluate current evidence of the effect of specialised nutritional interventions on nutritional status, survival, quality of life and measures of functionality in patients with incurable cancer.

Methods

Systematic literature review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed/MEDLINE, EMBASE, Scopus, LILACS and Cochrane Library databases. Clinical studies that evaluated different specialised nutritional interventions, such as nutritional counselling, oral nutritional supplementation (ONS), enteral nutrition (EN) and parenteral nutrition (PN), were eligible. Only studies classified as being of high methodological quality (ie, low or moderate risk of bias) were included.

Results

A total of 22 studies reporting on 2448 patients were deemed eligible. Five types of specialised nutrition were observed: mixed (multimodal nature, ie, dietary counseling, ONS, physical activity and/or drugs) (n=12), ONS (n=5), PN (n=3), EN (n=1) and multidisciplinary team counselling (n=1). Benefits of any kind from the interventions were reported in 14 (63.6%) studies, mainly resulting from mixed intervention. Nutritional status improved in 12 (60.0%) of 20 studies and quality of life improved in eight (50.0%) of 16 studies. Few studies have evaluated the influence of nutritional interventions on survival and measure of functionality, and have not shown improvement in these outcomes.

Conclusion

Despite the limited evidence, specialised nutritional interventions can yield positive effects for patients with incurable cancer, mainly in their nutritional status and quality of life.

Appetite in Palliative Cancer Patients and Its Association with Albumin, CRP and Quality of Life in Men and Women—Cross-Sectional Data from the Palliative D-Study

Albumin is an important biochemical marker in palliative cancer care, used for assessment of nutritional status, disease severity and prognosis. Our primary aim was to investigate sex differences in the association between appetite and albumin levels in palliative cancer patients. We also aimed to study associations between appetite and C-reactive protein (CRP), Quality of Life (QoL), pain and fatigue. In the Palliative D-cohort, consisting of 266 men and 264 women, we found a correlation between appetite and albumin; low appetite, measured with the Edmonton Symptom Assessment System, correlated significantly with low albumin in men: (r = −0.33, p < 0.001), but not in women (r = −0.03, p = 0.65). In a regression analysis adjusted for confounding factors, results were similar. Lower appetite was correlated with higher CRP in men (r = 0.27, p < 0.001), but not in women (r = 0.12, p = 0.05). Appetite was correlated with QoL, fatigue and pain in both men and women; those with a low appetite had a low QoL and high fatigue- and pain-scores (p < 0.001). In conclusion, our results indicated possible sex differences in the associations between appetite and albumin, and between appetite and CRP, in palliative care patients. Understanding these associations could provide additional value for clinical practice.

The Determination of a Consensus Nutritional Approach for Cancer Patients in Spain Using the Delphi Methodology

Malnutrition has a multifactorial origin and can be caused by cancer. This study determined the consensus of a panel of experts on the nutritional approach for cancer patients in Spain using a multidisciplinary approach. Using the Delphi methodology, a 74-question questionnaire was prepared and sent to 46 experts. The areas of knowledge addressed were the nutritional status of the cancer patient, nutritional screening, nutritional therapy, patient referral, and multidisciplinary care. A total of 91.7% of the experts agreed with the questions posed on nutritional status, 60.0% with those on nutritional screening, 76.7% with those on nutritional therapy, and the entire panel of experts agreed with the questions posed on patient referral and multidisciplinary care. The experts agreed upon a high prevalence of malnutrition among cancer patients in Spain. Unlike medical and radiation oncologists, medical nutrition specialists believe that body composition assessment should not be carried out in all types of cancer patients during nutritional screening and that interventions can be conducted outside the oncology clinic. In general, it is recommended that nursing staff routinely perform nutritional screening before starting cancer treatment. It is necessary to develop a multidisciplinary action protocol that includes nutritional and/or sarcopenia screening.

Association between oral health and advisability of oral feeding in advanced cancer patients receiving palliative care: a cross-sectional study

PURPOSE

Maintenance of oral feeding is important in terms of maintaining and improving the quality of life in terminal cancer patients receiving palliative care. Although adequate oral health status is essential for oral feeding in hospitalized patients, the relationship between oral health and oral feeding in patients receiving palliative care remains unclear. This cross-sectional study aimed to examine how the general condition and oral health status of these patients relate to decisions regarding their nutritional intake methods.

METHODS

This retrospective cross-sectional study included 103 terminal cancer patients (59 men and 44 women; mean age, 73.8 ± 10.9 years) who received palliative care between April 2017 and August 2019. The nutritional method was assessed using the Functional Oral Intake Scale (FOIS). We assessed two types of nutritional methods: (1) the method advised by the attending physician until the initial dental examination (FOIS-I) and (2) the recommended method based on consultation with a palliative care doctor and dentist after the initial oral examination (FOIS-R). Furthermore, the participants' basic information and Dysphagia Severity Scale (DSS) and Oral Health Assessment Tool (OHAT) scores were assessed.

RESULTS

There was a divergence between FOIS-I and FOIS-R. FOIS-R was significantly higher than FOIS-I (p < 0.001). Multiple regression analysis revealed that the time until death, DSS score, and OHAT score had a significant impact on determining the food form for oral feeding.

CONCLUSIONS

Appropriate oral health assessment is important in determining the food form and indication for oral feeding among patients receiving palliative care.

Palliative Care and End-of-Life Issues in Elderly Cancer Patients With Head and Neck Cancer

The number of elderly patients with incurable head and neck cancer will increase. They are in need of geriatric palliative care, that takes into account oncology, palliative care and geriatric medicine. In this review of the most recent and relevant literature and includes the expert opinion of the authors, several physical problems (e.g. pain, fatigue, malnutrition, and loco-regional problems) encountered by the elderly head and neck cancer patients are addressed. In addition end-of life issues in this patient population are discussed.

Decision Making of Artificial Nutrition and Hydration for Cancer Patients at Terminal Stage-A Systematic Review of the Views From Patients, Families, and Healthcare Professionals

BACKGROUND

Decision making on nutrition and hydration for cancer patients during terminal stage cause critical impacts toward patient's comfort and living quality. The management of nutrition is the main dilemma that arises in these final situations and has been the subject of intense debate over the last few decades.

AIM

To find the views of patients, families, and healthcare professionals related to how decisions are made when cancer patients are at terminal stage.

DESIGN

This systematic review used PRISMA strategy to search and used Critical Appraisal Skills Programme checklist to evaluate the papers.

DATA SOURCES

All English papers through August 2020 that contained the view of the decision making at artificial nutrition and hydration with cancer patients, families, and healthcare professionals at terminal stage were included. Selected studies were independently reviewed, and data collaboratively synthesized into core themes.

RESULTS

Most of the terminal stage cancer patients and their families initially started the decision-making process when facing the reduction of oral intake. There are two primary considerations of patients and families, one is for prolonging patients life, and the other is to maintain their life quality. The voices of patients were influential, but not determinative; families usually had influence, but seldom make the final recommendation by themselves; healthcare professionals frequently face the dilemma about their decision.

CONCLUSION

The decision of nutritional support was dynamic; the interaction between patients and families frequently be hesitated to protect the rights of life, unnecessarily prolonging lifetime. Therefore, a better understanding of the views on nutritional support and processing the clinical guideline of decision making for healthcare professional is necessary.

Jejunostomy in the palliative treatment of gastric cancer: A clinical prognostic score

BACKGROUND

Clinical stage IV gastric cancer (GC) may need palliative procedures in the presence of symptoms such as obstruction. When palliative resection is not possible, jejunostomy is one of the options. However, the limited survival of these patients raises doubts about who benefits from this procedure.

AIM

To create a prognostic score based on clinical variables for 90-d mortality for GC patients after palliative jejunostomy.

METHODS

We performed a retrospective analysis of Stage IV GC who underwent jejunostomy. Eleven preoperative clinical variables were selected to define the score categories, with 90-d mortality as the main outcome. After randomization, patients were divided equally into two groups: Development (J1) and validation (J2). The following variables were used: Age, sex, body mass index (BMI), American Society of Anesthesiologists classification (ASA), Charlson Comorbidity index (CCI), hemoglobin levels, albumin levels, neutrophil-lymphocyte ratio (NLR), tumor size, presence of ascites by computed tomography (CT), and the number of disease sites. The score performance metric was determined by the area under the receiver operating characteristic (ROC) curve (AUC) to define low and high-risk groups.

RESULTS

Of the 363 patients with clinical stage IVCG, 80 (22%) patients underwent jejunostomy. Patients were predominantly male (62.5%) with a mean age of 62.4 years old. After randomization, the binary logistic regression analysis was performed and points were assigned to the clinical variables to build the score. The high NLR had the highest value. The ROC curve derived from these pooled parameters had an AUC of 0.712 (95%CI: 0.537-0.887, P = 0.022) to define risk groups. In the validation cohort, the diagnostic accuracy for 90-d mortality based on the score had an AUC of 0.756, (95%CI: 0.598-0.915, P = 0.006). According to the cutoff, in the validation cohort BMI less than 18.5 kg/m2 (P < 0.001), CCI ≥ 1 (P = 0.001), ASA III/IV (P = 0.002), high NLR (P = 0.012), and the presence of ascites on CT exam (P = 0.004) were significantly associated with the high-risk group. The risk groups showed a significant association with first-line (P = 0.012), second-line chemotherapy (P = 0.009), 30-d (P = 0.013), and 90-d mortality (P < 0.001).

CONCLUSION

The scoring system developed with 11 variables related to patient's performance status and medical condition was able to distinguish patients undergoing jejunostomy with high risk of 90 d mortality.

Nutritional Support Indications in Gastroesophageal Cancer Patients: From Perioperative to Palliative Systemic Therapy. A Comprehensive Review of the Last Decade

Gastric cancer treatments are rapidly evolving, leading to significant survival benefit. Recent evidence provided by clinical trials strongly encouraged the use of perioperative chemotherapy as standard treatment for the localized disease, whereas in the advanced disease setting, molecular characterization has improved patients’ selection for tailored therapeutic approaches, including molecular targeted therapy and immunotherapy. The role of nutritional therapy is widely recognized, with oncologic treatment’s tolerance and response being better in well-nourished patients. In this review, literature data on strategies or nutritional interventions will be critically examined, with particular regard to different treatment phases (perioperative, metastatic, and palliative settings), with the aim to draw practical indications for an adequate nutritional support of gastric cancer patients and provide an insight on future directions in nutritional strategies. We extensively analyzed the last 10 years of literature, in order to provide evidence that may fit current clinical practice both in terms of nutritional interventions and oncological treatment. Overall, 137 works were selected: 34 Randomized Clinical Trials (RCTs), 12 meta-analysis, 9 reviews, and the most relevant prospective, retrospective and cross-sectional studies in this setting. Eleven ongoing trials have been selected from clinicaltrial.gov as representative of current research. One limitation of our work lies in the heterogeneity of the described studies, in terms of sample size, study procedures, and both nutritional and clinical outcomes. Indeed, to date, there are no specific evidence-based guidelines in this fields, therefore we proposed a clinical algorithm with the aim to indicate an appropriate nutritional strategy for gastric cancer patients.

Validation of the scored Patient-Generated Subjective Global Assessment Short Form as a prognostic tool for patients with incurable cancer

BACKGROUND

The Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF) is a standardized tool for assessing nutrition risk in patients with cancer. The aim of this study was to propose and validate a cutoff point for the PG-SGA SF related to the prognosis of patients with incurable cancer in exclusive palliative care.

METHODS

This is a prospective cohort study of patients with incurable cancer at the National Cancer Institute in Brazil. A total sample (n = 2,144) was randomly divided into groups: (1) training (n = 1,072), to determine the most accurate PG-SGA SF cutoff, and (2) validation (n = 1,072), to test the predictive accuracy of this cutoff point. The receiver operating characteristic curve was plotted to determine the best cutoff point of the PG-SGA SF related to death. Concordance statistics (C statistic) were used to test the predictive accuracy of the models. Kaplan-Meier curve and the Cox hazard model were used to verify a prognostic value of the cutoff point.

RESULTS

PG-SGA SF score ≥15 was found to be the best cutoff based on 90-day mortality with good accuracy discrimination (C statistic ≥ 0.74). Patients whose PG-SGA SF score was ≥15 had a shorter survival of 32 (interquartile range [IQR], 12-75) vs 83 days (IQR, 31-90) (p-value < .001) and higher risk of death (hazard ratio: 2.20; 95% CI, 1.64-2.95).

CONCLUSIONS

The proposed PG-SGA SF cutoff score is valid and, alongside its usefulness in nutrition triage, could provide prognostic value for patients with incurable cancer.

Clinical nutrition as part of the treatment pathway of pancreatic cancer patients: an expert consensus

Purpose

Malnutrition is a common problem among pancreatic cancer (PC) patients that negatively impacts on their quality of life (QoL) and clinical outcomes. The main objective of this consensus is to address the role of Medical Nutrition Therapy (MNT) into the comprehensive therapeutic management of PC patients.

Methods

A Spanish multidisciplinary group of specialists from the areas of Medical Oncology; Radiation Oncology; Endocrinology and Nutrition; and General Surgery agreed to assess the role of MNT as part of the best therapeutic management of PC patients.

Results

The panel established different recommendations focused on nutritional screening and nutritional screening tools, MNT strategies according to PC status, and MNT in palliative treatment.

Conclusions

There is an unmet need to integrate nutritional therapy as a crucial part of the multimodal care process in PC patients. Health authorities, health care professionals, cancer patients, and their families should be aware of the relevance of nutritional status and MNT on clinical outcomes and QoL of PC patients.

Enteral Nutrition by Nasogastric Tube in Adult Patients under Palliative Care: A Systematic Review

Nutritional management of patients under palliative care can lead to ethical issues, especially when Enteral Nutrition (EN) is prescribed by nasogastric tube (NGT). The aim of this review is to know the current status in the management of EN by NG tube in patients under palliative care, and its effect in their wellbeing and quality of life. The following databases were used: PubMed, Web of Science (WOS), Scopus, Scielo, Embase and Medline. After inclusion and exclusion criteria were applied, as well as different qualities screening, a total of three entries were used, published between 2015 and 2020. In total, 403 articles were identified initially, from which three were selected for this review. The use of NGT caused fewer diarrhea episodes and more restrictions than the group that did not use NG tubes. Furthermore, the use of tubes increased attendances to the emergency department, although there was no contrast between NGT and PEG devices. No statistical difference was found between use of tubes (NGT and PEG) or no use, with respect to the treatment of symptoms, level of comfort, and satisfaction at the end of life. Nevertheless, it improved hospital survival compared with other procedures, and differences were found in hospital stays in relation to the use of other probes or devices. Finally, there are not enough quality studies to provide evidence on improving the health status and quality of life of the use of EN through NGT in patients receiving palliative care. For this reason, decision making in this field must be carried out individually, weighing the benefits and damages that they can cause in the quality of life of the patients.
