Prognostic Significance of Serum Interleukin-6 Levels in Oral Squamous Cell Carcinoma

Introduction The prognosis of oral squamous cell carcinoma (OSCC) is often poor despite standard treatments. Additionally, no useful prognostic markers are available. Therefore, we aimed to investigate the relationship between serum Interleukin-6 (IL-6) levels and prognosis and explore its local and systemic effects in patients with OSCC. Methods Ninety-five new cases of OSCC were included, and the prognosis was compared between high and low serum IL-6 groups. The localization of IL-6 in OSCC tissues was examined. Furthermore, a comprehensive gene expression analysis was performed in OSCC tissues and compared between the two groups. Results A significant difference in overall survival and disease-free survival was observed. Furthermore, a substantial expression of IL-6 was localized in the stroma. Comprehensive gene expression analysis of tumor localization showed increased expression of genes related to oxidoreductase and lipid metabolism in the primary tissues of the group with high serum IL-6 levels. Regarding the correlation between blood tests and serum IL-6 levels, a strong positive correlation was observed between inflammatory responses and nutritional factors. Conclusion These results suggest that serum IL-6 may be a prognostic factor for metabolic abnormalities in patients with OSCC and that aggressive nutritional interventions may contribute to prognosis.

The effect of oral dietary interventions on nutritional status and treatment tolerance in patients with hematologic neoplasms receiving chemotherapy: a systematic review

CONTEXT

Adverse events from chemotherapy treatment affect food intake, nutritional status, and treatment tolerance in cancer patients. However, the effect of nutritional intervention in patients with hematologic neoplasms receiving chemotherapy remains unknown.

OBJECTIVE

The aim of this systematic review was to evaluate the evidence on nutritional interventions on nutritional status, treatment tolerance, inflammatory markers, quality of life, and mortality in patients with hematologic neoplasms receiving chemotherapy.

DATA SOURCES

The MEDLINE, LILACS, CINAHL, Web of Science, Embase, ICTRP, CENTRAL, and ClinicalTrials.gov databases were searched. Additional literature and the bibliographies of identified articles were also considered.

DATA EXTRACTION

Randomized controlled trials in individuals with hematologic neoplasms receiving chemotherapy along with nutritional counseling and oral nutritional supplementation, and intake of supplementary food products, alone or in combination, were assessed as criteria of interest. The data were extracted independently by 2 researchers. The risk of bias was assessed through the Cochrane risk-of-bias tool (RoB 2).

DATA ANALYSIS

Ten studies were included up to August 15, 2022 (updated in November of 2022). With regard to the outcomes, 4 studies assessed nutritional status and 2 studies showed a positive result of the intervention on some of the markers. Seven studies assessed certain markers of treatment tolerance and only 2 studies showed improvement in the outcome after the intervention.

CONCLUSION

The studies that found positive results are quite different from each other in terms of intervention, study time, and design. More randomized controlled trials are needed to test different dietary interventions using placebo and blinding, when possible, and with reduced sample variability in individuals with hematologic neoplasms receiving chemotherapy.

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.

Effects of PEG in patients with esophageal squamous cell carcinoma during concurrent chemoradiotherapy: a prospective study

BACKGROUND AND AIMS

This prospective study aimed to compare the changes in nutritional status and adverse events among patients with esophageal squamous cell carcinoma who received enteral nutrition through oral intake, PEG, and an enteral nasogastric tube (NGT) during concurrent chemoradiotherapy (CCRT).

METHODS

Of 141 included patients, 38, 74, and 29 patients were fed through oral intake, PEG, and NGTs, respectively. The clinical characteristics and baseline nutritional status of the 3 groups were recorded and analyzed. The Patient-Generated Subjective Global Assessment score, skeletal muscle index, and quality of life were evaluated before and after CCRT; the incidence of adverse events during feeding using PEG and NGTs was also recorded. The correlations among the different nutritional pathways and the CCRT-related adverse events (eg, radiation esophagitis and myelosuppression) were assessed.

RESULTS

At baseline, the oral intake group had a significantly better nutritional status and lower disease stage than those in the PEG and NGT groups. However, during CCRT, the oral intake group exhibited the most significant decreases in weight and skeletal muscle index. The synchronous chemotherapy completion rate was the highest in the PEG group. Multivariate analysis showed that the planning tumor volume and oral intake and NGT feeding pathways were associated with radiation esophagitis of at least grade 2.

CONCLUSIONS

We found that PEG effectively maintained the body weight and skeletal muscle index of patients with esophageal cancer during CCRT. PEG also improved the synchronous chemotherapy completion rate and reduced the occurrence of at least grade 2 radiation esophagitis. (Clinical trial registration number: NCT04199832.).

An adult Drosophila glioma model to highlight metabolic dysfunctions and evaluate the role of the serotonin 5-HT7 receptor as a potential therapeutic target

Gliomas account for 50% of brain cancers and are therefore the most common brain tumors. Molecular alterations involved in adult gliomas have been identified and mainly affect tyrosine kinase receptors with amplification and/or mutation of the epidermal growth factor receptor (EGFR) and its associated signaling pathways. Several targeted therapies have been developed, but current treatments remain ineffective for glioblastomas, the most severe forms. Thus, it is a priority to identify new pharmacological targets. Drosophila glioma models established in larvae and adults are useful to identify new genes and signaling pathways involved in glioma progression. Here, we used a Drosophila glioma model in adults, to characterize metabolic disturbances associated with glioma and assess the consequences of 5-HT7 R expression on glioma development. First, by using in vivo magnetic resonance imaging, we have shown that expression of the constitutively active forms of EGFR and PI3K in adult glial cells induces brain enlargement. Then, we explored altered cellular metabolism by using high-resolution magic angle spinning NMR and 1 H-13 C heteronuclear single quantum coherence solution states. Discriminant metabolites identified highlight the rewiring of metabolic pathways in glioma and associated cachexia phenotypes. Finally, the expression of 5-HT7 R in this adult model attenuates phenotypes associated with glioma development. Collectively, this whole-animal approach in Drosophila allowed us to provide several rapid and robust phenotype readouts, such as enlarged brain volume and glioma-associated cachexia, as well as to determine the metabolic pathways involved in glioma genesis and finally to confirm the interest of the 5-HT7 R in the treatment of glioma.

Medical nutrition therapy during intensive remission-induction treatment and hematopoietic stem cell transplantation in acute myeloid leukemia patients: Hematologists' experiences and perspectives

BACKGROUND & AIMS

The European Societies for Clinical Nutrition and Metabolism (ESPEN) and Blood and Marrow Transplantation (EBMT) recommend enteral nutrition (EN) as the first-choice medical nutrition therapy in acute myeloid leukemia (AML) patients undergoing intensive treatments, including high-dose remission-induction chemotherapy and hematopoietic stem cell transplantation (HSCT). However, parenteral nutrition (PN) remains the preferred method of nutrition support in current clinical practice. The aim of this qualitative study was to gain insight into hematologists' experiences and perspectives regarding the choice and ESPEN/EBMT recommendations on EN versus PN.

METHODS

Online semi-structured interviews were conducted with one hematologist from each of the 21 hospitals offering intensive AML treatments in the Netherlands, using Microsoft Teams. Interviews were audio-recorded, transcribed verbatim and thematically analyzed using Atlas. ti. One hundred nineteen hematologists working in the same hospitals were invited to complete a short online questionnaire survey (SurveyMonkey®) regarding their knowledge and opinion on the ESPEN/EBMT guidelines recommending EN over PN during intensive AML treatments. The results of this survey are presented in a descriptive way.

RESULTS

Fifty-nine hematologists participated in this study (42% overall response rate), of which 21 in the semi-structured interviews (response rate 100%) and 38 in the online survey (response rate 32%). Hematologists considered medical nutrition therapy important for prevention and treatment of malnutrition and associated adverse outcomes in AML patients undergoing intensive remission-induction treatment and HSCT. However, opposed to the ESPEN/EBMT guidelines, the vast majority of hematologists were hesitant or reluctant to use EN instead of PN as the first-choice medical nutrition therapy in these patients. The most frequently cited barriers to use EN were the expected low feasibility and tolerance of EN, feeding tube-related discomfort and bleeding risk, and patient refusal. Other barriers to follow the guidelines on EN were related to personal factors, including hematologists' knowledge (lack of awareness and familiarity) and attitude (lack of agreement, outcome expectancy, experience, success, motivation, and learning culture), guideline-related factors (lack of evidence and applicability), and external factors (lack of collaboration and resources). Facilitators included strategies for nutrition education and dissemination of nutritional guidelines, interprofessional and patient collaboration, availability of feeding tubes that can be inserted without endoscopy and stronger scientific evidence.

CONCLUSIONS

Hematologists recognized the importance of medical nutrition therapy for reducing malnutrition and related negative outcomes during intensive AML treatments. However, contrary to the ESPEN/EBMT guidelines, they preferred PN instead of EN as the medical nutrition therapy of first choice. To reduce compliance barriers, interventions should focus on improving hematologists' knowledge of medical nutrition therapy and dietary guidelines, enhancing success rates of EN by adequately triaging patients eligible for EN and inserting duodenal feeding tubes using an electromagnetic sensing device without endoscopy, developing decision aids and multidisciplinary guidelines and care pathways. Furthermore, future trials should focus on the feasibility and benefits of EN versus PN both during remission-induction treatment and HSCT.

Impact of sarcopenia on S1 adjuvant chemotherapy and prognosis in pancreatic cancer patients

Although the importance of adjuvant chemotherapy (AC) has been recognized in pancreatic cancer (PC) patients, there are few studies to address the underlying mechanisms of failure to complete AC. This study aims to investigate the relationship between nutritional state represented by sarcopenia and failure to complete AC in patients after curative-intent surgery for PC. This study included 110 patients who underwent pancreaticoduodenectomy for potentially resectable pancreatic cancers with intention of adjuvant S-1. Sarcopenia was defined using the psoas muscle mass index with cutoff values of 6.36 cm2/m2 for men and 3.92 cm2/m2 for women, which were calculated with a 3-D volumetric software. The relation between sarcopenia and successful AC and long-term survival were investigated. Twenty-nine (26%) patients were diagnosed as having sarcopenia (Sarcopenia group). Sarcopenia group comprised significantly older patients than Non-sarcopenia group (72 vs. 67 years old, p = 0.0087). AC was successfully completed in 14 patients (48%) in Sarcopenia group compared to 72 patients (89%) in Non-sarcopenia group (p < 0.0001). Multivariate analysis identified age ≥ 70 years and sarcopenia as significant risk factors for failure of AC. Among patients ≥ 70 years old, rate of successful AC was significantly higher in sarcopenia groups than non-sarcopenia group (17% vs. 78%, p < 0.001). In conclusions, age and sarcopenia were critical risk factors for the failure of 6 months of adjuvant chemotherapy. Among elderly patients, sarcopenia can predict the poor success rate of AC.

[ESPEN practical guideline: Home enteral nutrition]

Introduction

This ESPEN practical guideline will inform physicians, nurses, dieticians, pharmacists, caregivers and other home enteral nutrition (HEN) providers in a concise way about the indications and contraindications for HEN, as well as its implementation and monitoring. This guideline will also inform interested patients requiring HEN. Home parenteral nutrition is not included but will be addressed in a separate ESPEN guideline. The guideline is based on the ESPEN scientific guideline published before, which consists of 61 recommendations that have been reproduced and renumbered, along with the associated commentaries that have been shorted compared to the scientific guideline. Evidence grades and consensus levels are indicated. The guideline was commissioned and financially supported by ESPEN and the members of the guideline group were selected by ESPEN.

Efficacy and cost-effectiveness analysis of pretreatment percutaneous endoscopic gastrostomy in unresectable locally advanced esophageal cancer patients treated with concurrent chemoradiotherapy (GASTO 1059)

BACKGROUND

We launched a single-arm phase II study to determine the efficacy and cost-effectiveness of percutaneous endoscopic gastrostomy (PEG) before concurrent chemoradiotherapy (CCRT) in patients with esophageal squamous cell carcinoma (ESCC).

METHODS

Eligible patients received pretreatment PEG and enteral nutrition during CCRT. The primary outcome was the change of weight during CCRT. The secondary outcome included nutrition status, loco-regional objective response rate (ORR), loco-regional progression-free survival (LRFS), overall survival (OS), and toxicities. A 3-state Markov model was applied for cost-effectiveness analysis. Eligible patients were matched and compared with those who had nasogastric tube feeding (NTF) or oral nutritional supplements (ONS).

RESULTS

Sixty-three eligible patients received pretreatment PEG-based CCRT. The mean change of weight during CCRT was -1.4% (standard deviation, 4.4%), and after CCRT, 28.6% of patients gained weight and 98.4% had normal albumin levels. The loco-regional ORR and 1-year LRFS were 98.4% and 88.3%. The incidence of grade ≥3 esophagitis was 14.3%. After matching, another 63 patients were included in the NTF group and 63 in the ONS group. More patients gained weight after CCRT in the PEG group (p = 0.001). The PEG group showed higher loco-regional ORR (p = 0.036) and longer 1-year LRFS (p = 0.030). In cost analysis, the PEG group showed an incremental cost-effectiveness ratio of $3457.65 per quality-adjusted life-years (QALY) compared with the ONS group with a probability of cost-effectiveness of 77.7% at the $10,000 per QALY willingness-to-pay threshold.

CONCLUSION

Pretreatment PEG is associated with better nutritional status and treatment outcome in ESCC patients treated with CCRT compared with ONS and NTF. Pretreatment of PEG can be cost-effective because of its significant clinical benefits.

Effect of prophylactic tube feeding in head and neck cancer patients with high Mallampati score undergoing definitive concurrent chemoradiotherapy

PURPOSE

There is no consensus on the selection of appropriate prophylactic tube feeding in patients with head and neck squamous cell carcinoma (HNSCC) undergoing concurrent chemoradiotherapy (CCRT). This study aimed to evaluate the effect of prophylactic tube feeding in patients with HNSCC who presented with a high Mallampati score and underwent CCRT.

METHODS

We prospectively enrolled 185 consecutive patients with stage II to IVa HNSCC and a pre-treatment Mallampati score of 3 or 4 who received CCRT between August 2017 and December 2018 with follow-up data collected retrospectively. Patients were divided to either with or without prophylactic tube feeding group for comparison of treatment tolerance, toxicities, and quality of life(QOL). Propensity score matching (PSM) was used to achieve balanced covariates across the two groups.

RESULTS

Of the cohort, 52 (28.1%) and 133 (71.9%) patients were allocated to the prophylactic and non-prophylactic tube feeding groups, respectively. Before and after PSM, patients in the tube feeding group had a significantly lower incidence of incomplete radiotherapy, incompletion of chemotherapy, emergency room visits, and grade 3 or higher infection, and improved symptoms of quality of life after CCRT than those in the non-tube feeding group.

CONCLUSION

Prophylactic tube feeding was associated with better treatment tolerance, safety profiles, and quality of life in patients with HNSCC and high Mallampati scores who underwent CCRT. Therefore, Mallampati score might serve as a clinical tool for proactive selection of patients receiving prophylactic tube feeding in HNSCC patients upon receiving CCRT.

Nasogastric tube feeding improves nutritional status and physical state in esophageal cancer patients during chemoradiotherapy: a retrospective study

OBJECTIVE

To compare the complication rates, nutritional status, and physical state between esophageal cancer (EC) patients managed by nasogastric tube (NGT) feeding versus those managed by oral nutritional supplementation (ONS) during chemoradiotherapy.

METHODS

EC patients undergoing chemoradiotherapy managed by nonintravenous nutritional support in our institute were retrospectively recruited and divided into an NGT group and an ONS group based on the nutritional support method. The main outcomes, including complications, nutritional status, and physical state, were compared between groups.

RESULTS

The baseline characteristics of EC patients were comparable. There were no significant differences in the incidence of treatment interruption (13.04% vs. 14.71%, P = 0.82), death (2.17% vs. 0.00%, P = 0.84), or esophageal fistula (2.17% vs. 1.47%, P = 1.00) between the NGT group and ONS group. Body weight loss and decrease in albumin level were significantly lower in the NGT group than in the ONS group (both P < 0.05). EC patients in the NGT group had significantly lower Nutritional Risk Screening 2002 (NRS2002) and Patient-Generated Subjective Global Assessment (PG-SGA) scores and significantly higher Karnofsky Performance Status (KPS) scores than patients in the ONS group (all P < 0.05). The rates of grade > 2 esophagitis (10.00% vs. 27.59%, P = 0.03) and grade > 2 bone marrow suppression (10.00% vs. 32.76%, P = 0.01) were significantly lower in the NGT group than in the ONS group. There were no significant differences in the incidence of infection and upper gastrointestinal disorders or therapeutic efficacy between groups (all P > 0.05).

CONCLUSIONS

EN through NGT feeding leads to significantly better nutritional status and physical state in EC patients during chemoradiotherapy than EN via ONS. NGT may also prevent myelosuppression and esophagitis..

Developing guidance for feeding tube administration of oral medications

BACKGROUND

Drug administration through feeding tubes presents many challenges to the healthcare provider. There is little information available on medications than can be delivered safely when crushed and what efforts can be implemented to minimize clogging the feeding tube. Our institution requested a comprehensive examination of all oral medications for the feeding tube route.

METHODS

This report is a synopsis of the physical evaluation of 323 different oral medications for their appropriateness for feeding tube administration with distal site in either the stomach or jejunum. A worksheet was created for each medication. This document contained a review of the chemical and physical properties that would contribute to delivery of the medication. Each medication was then studied for the degree of disintegration, pH, osmolality, and potential to form clogs. For drugs that needed to be crushed, the volume of water needed to dissolve the drug, time for that process, and volume needed to rinse the tube after administration was also studied.

RESULTS

The results of this review are summarized in a table and based on a composite of the documents cited, tests conducted, and author's judgements based all the data collected. Thirty-six medications were identified as inappropriate for feeding tube administration, and an additional 46 medications were identified as inappropriate for direct jejunal administration.

CONCLUSION

The information produced by this study will enable clinicians to make informed choices in selecting, compounding, and rinsing medications through feeding tubes. Using the template provided, they will be able to evaluate a drug not studied here for potential issues in feeding tube administration.

Enteral Nutrition during Radiotherapy for Oropharyngeal Cancers: Prevalence and Prognostic Factors Based on HPV Status (A GETTEC Study)

Nutritional support during radiotherapy is crucial to tolerating and completing oropharyngeal squamous cell carcinoma (OPSCC) treatment. The impact of HPV status on nutritional support is debated. The objective was to evaluate the rate of Reactive Feeding Tube (RFT) use and determine its prognostic factors during definitive radiotherapy for OPSCC. All OPSCC patients treated from 2009 to 2014 were included in this multicentric retrospective study. The impact of tumor p16 status on the risk of RFT was assessed through multivariate analyses. Among the 543 patients, 103 patients required an RFT (19.0%). The use of RFT differed between centers (5% to 32.4%). In multivariate analysis, only tongue base involvement and concurrent chemotherapy were significantly associated with RFT (OR = 2.18 and 3.7, respectively). Tongue base involvement and concomitant chemotherapy were prognostic factors for RFT. HPV status was not a prognostic factor for enteral nutrition during radiotherapy for OPSCC.

The prognostic indicator in breast cancer treated with CDK4/6 inhibitors: the prognostic nutritional index

Aims: The aim of this study was to evaluate the effect of prognostic nutritional index (PNI) on prognosis in patients with hormone receptor-positive, HER2-negative metastatic breast cancer who received CDK4/6 inhibitor + endocrine therapy. Methods: Patients receiving a CDK4/6 inhibitor were evaluated retrospectively. The PNI was calculated as: (10 × serum albumin [g/dl]) + (total lymphocyte count [×10⁹/l] × 5). Results: In a study of 106 patients, a statistically significant survival advantage was observed in the high-PNI group over the low-PNI group (mean overall survival: 28.03 ± 0.487 months vs 22.46 ± 1.14 months; p = 0.013). Conclusion: For the first time in the literature, this study demonstrated the prognostic role of PNI in patients with hormone receptor-positive, HER2-negative metastatic breast cancer treated with CDK4/6 inhibitors.

Nutritional Management of Patients with Head and Neck Cancer-A Comprehensive Review

While surgical therapy for head and neck cancer (HNC) is showing improvement with the advancement of reconstruction techniques, the focus in these patients should also be shifting to supportive pre and aftercare. Due to the highly sensitive and anatomically complex region, these patients tend to exhibit malnutrition, which has a substantial impact on their recovery and quality of life. The complications and symptoms of both the disease and the therapy usually make these patients unable to orally intake food, hence, a strategy should be prepared for their nutritional management. Even though there are several possible nutritional modalities that can be administrated, these patients commonly have a functional gastrointestinal tract, and enteral nutrition is indicated over the parenteral option. However, after extensive research of the available literature, it seems that there is a limited number of studies that focus on this important issue. Furthermore, there are no recommendations or guidelines regarding the nutritional management of HNC patients, pre- or post-operatively. Henceforth, this narrative review summarizes the nutritional challenges and management modalities in this particular group of patients. Nonetheless, this issue should be addressed in future studies and an algorithm should be established for better nutritional care of these patients.

Multidisciplinary nutritional management improves nutritional and hospitalized outcomes of patients with esophageal cancer undergoing chemoradiotherapy: A randomized control trial

BACKGROUND

This study aimed to investigate the effects of multidisciplinary whole-course nutrition management on the nutritional status and complications during the course of treatment in patients with esophageal cancer (EC) undergoing chemoradiotherapy.

METHODS

A total of 36 EC patients undergoing chemoradiotherapy were divided into a control group (n = 18) and an intervention group (n = 18). Participants in the control group were given routine nutritional support, whereas those in the intervention group were provided whole-course nutrition management from the nutrition support team. Nutrition-related indicators, that is, serum albumin level (ALB), hemoglobin (Hb), and C reactive protein were assessed before, during, and after treatment in both groups. The incidence of complications (e.g., lymphocytopenia, radiation esophagitis, and myelosuppression), clinical outcomes, length of hospital stay, and hospital costs were also recorded. Differences between the 2 groups were tested using the Mann-Whitney U and chi-square tests.

RESULTS

The ALB and Hb levels of the patients in the control group decreased significantly [ALB: -2.6 (-5.6, 0), P = .01; Hb: -12.0 (-27.0, -2.0), P = .04] and C reactive protein increased [8.9 (2.9, 14.9), P = .02] compared to those before treatment, while the indicators of participants in the intervention group did not change (P > .05). The incidence of grade ≥ II lymphocytopenia was higher in the control group than that in the intervention group (33.3% vs 61.1%, P = .03). Moreover, compared with the control group, the average length of hospital stay decreased by 12 days [47 (40, 50) vs 35 (23, 40), P = .001], and in-patient expenses decreased by 20,504 CNY in the intervention group (P = .004).

CONCLUSION

Multidisciplinary whole-course nutrition management can maintain the nutritional status of patients with EC undergoing chemoradiotherapy. This may lower the incidence of complications, shorten hospital stays, and reduce in-patient expenses.

Using coword analysis and chord diagrams to examine the effect of nutritional counseling and support (DCNS) on patients with oral and oropharyngeal cancer

BACKGROUND

Dietary counseling and nutritional support (DCNS) are generally accepted as being necessary for patients with oral cancer and oropharyngeal cancer (OC). However, there is no evidence that dietary counseling plays a significant role in weight loss. In this study, we examined the DCNS based on persistent weight loss during and after treatment in oral cancer and OC patients, as well as the effect of body mass index (BMI) on survival in both groups.

METHODS

A retrospective chart review was conducted on 2622 patients diagnosed with cancer between 2007 and 2020, including 1836 oral and 786 oropharyngeal patients. In comparison with the sample of patients treated by DCNS, differences in proportional counts for key factors associated with survival were compared between oral cancer and OC patients using the forest plot. An analysis of cowords was conducted to determine CNS associated with weight loss and overall survival. The Sankey diagram was used to display DCNS effectiveness. The log-rank test was used to evaluate the chi-squared goodness of fit test on the null assumption model of equal survival distributions between the groups.

RESULTS

Almost 41% of the patients (=1064/2262) received DCNS, with a frequency ranging from 1 to 44. Counts for 4 DCNS categories were 566, 392, 92, and 14, respectively, against BMI increases or decreases from much to less with counts of 3, 44, 795, 219, and 3, respectively. In the first year following treatment, DCNS decreased sharply to 50%. One year after hospital discharge, the overall weight loss increased from 3 to 9% (mean = -4%, standard deviation = 14%). Patients with a BMI above average had a significantly longer survival time (P < .001). Statistically, OC patients have a significantly higher survival rate than oral cancer patients.

CONCLUSION

Despite receiving frequent DCNS, patients continued to lose body weight during and 1 year after treatment. The survival time of an individual with a BMI above average appears to be increased. Future studies should preferably use randomized trials to compare standard DCNS with more intensive DCNS, which includes earlier and/or prolonged treatment.

Effects of induction chemotherapy on nutrition status in locally advanced nasopharyngeal carcinoma: a multicentre prospective study

BACKGROUND

Induction chemotherapy (IC) and concurrent chemoradiotherapy (CCRT) is the standard of care for locoregionally advanced nasopharyngeal carcinoma (LA-NPC). This intensive treatment regimen increases acute toxicities, which could negatively impact patients' nutritional status. We conducted this prospective, multicentre trial to investigate the effects of IC and CCRT on nutritional status in LA-NPC patients, so as to provide evidence for further study of nutritional intervention, which was registered in ClinicalTrials.gov (NCT02575547).

METHODS

Patients with biopsy-proven NPC and planned for IC + CCRT were recruited. IC entailed two cycles of 3-weekly docetaxel 75 mg/m² and cisplatin 75 mg/m² ; CCRT entailed two to three cycles of 3-weekly cisplatin 100 mg/m² depending on the duration of radiotherapy. Nutritional status and quality of life (QoL) were assessed pre-IC, post-cycles one and two of IC, W4 and W7 of CCRT. Primary endpoint was the cumulative proportion of ≥ 5.0% weight loss (WL_5.0 ) by the end of treatment (W7-CCRT). Secondary endpoints included body mass index, NRS2002 and PG-SGA scores, QoL, hypoalbuminaemia, treatment compliance, acute and late toxicities and survivals. The associations between primary and secondary endpoints were also evaluated.

RESULTS

One hundred and seventy-one patients were enrolled. Median follow-up was 67.4 (IQR: 64.1-71.2) months. 97.7% (167/171) patients completed two cycles of IC, and 87.7% (150/171) completed at least two cycles of concurrent chemotherapy; all, except one patient (0.6%), completed IMRT. WL was minimal during IC (median of 0.0%), but increased sharply at W4-CCRT (median of 4.0% [IQR: 0.0-7.0%]) and peaked at W7-CCRT (median of 8.5% [IQR: 4.1-11.7%]). 71.9% (123/171) of patients recorded a WL_5.0 by W7-CCRT, which was associated with a higher malnutrition risk (NRS2002 ≥ 3 points: 87.7% [WL ≥ 5.0%] vs 58.7% [WL < 5.0%], P < 0.001) and requirement of nutritional intervention (PG-SGA ≥ 9 points: 82.0% [WL ≥ 5.0%] vs 66.7% [WL < 5.0%], P = 0.038). The median %WL at W7-CCRT was higher in patients who suffered from ≥ G2 mucositis (9.0% vs 6.6%, P = 0.025) and xerostomia (9.1% vs 6.3%, P = 0.003). Besides, patients with cumulative WL_5.0 also reported a higher detriment on QoL at W7-CCRT compared with patients without, with a difference of -8.3 points (95% CI [-15.1, -1.4], P = 0.019).

CONCLUSIONS

We observed a high prevalence of WL among LA-NPC patients who were treated with IC + CCRT, which peaked during CCRT, and had a detriment on patients' QoL. Our data support the need to monitor patient's nutritional status during the later phase of treatment with IC + CCRT and inform on nutritional intervention strategies.

Mapping the global research landscape on nutritional support for patients with gastrointestinal malignancy: visualization analysis

BACKGROUND

Early nutritional treatment is crucial for the care of patients with operable and advanced gastrointestinal malignancies. Therefore, much research has focused on nutritional support for patients with gastrointestinal malignancies. Therefore, this study aimed to evaluate the global scientific output and activity with respect to nutritional support and gastrointestinal malignancy.

METHODS

We searched in Scopus for publications on gastrointestinal cancer and nutritional assistance published between January 2002 and December 2021. Then, using VOSviewer 1.6.18 and Microsoft Excel 2013, we conducted bibliometric analysis and visualization.

RESULTS

A total of 906 documents were published between 2002 and 2021, including 740 original articles (81.68%) and 107 reviews (11.81%). China ranked first (298 publications, 32.89%), Japan ranked second (86 publications, 9.49%) and the USA ranked third (84 publications, 9.27%). The organisation with the highest number of publications was the Chinese Academy of Medical Sciences & Peking Union Medical College from China, with 14 articles, followed by the Peking Union Medical College Hospital from China and the Hospital Universitari Vall d'Hebron from Spain (13 publications for each). Before 2016, most studies focused on 'nutrition support for patients undergoing gastrointestinal surgery'. However, the latest trends showed that 'nutrition support and clinical outcomes in gastrointestinal malignancies' and 'malnutrition in patients with gastrointestinal cancer' would be more widespread in the future.

CONCLUSIONS

This review is the first bibliometric study to provide a thorough and scientific analysis of gastrointestinal cancer and nutritional support trends worldwide over the last 20 years. This study can aid researchers in decision-making by helping them understand the frontiers and hotspots in nutrition support and gastrointestinal cancer research. Future institutional and international collaboration is expected to accelerate the advancement of gastrointestinal cancer and nutritional support research and investigate more efficient treatment methods.

[Impact of HPV status on nutritional status during radio chemotherapy for oropharyngeal cancer]

PURPOSE

Patients with oropharyngeal cancer are at high nutritional risk before and during treatment. Little is known about the influence of human papillomavirus (HPV) infection on nutritional status and its evolution during treatment.

MATERIALS AND METHODS

A single-center retrospective study was conducted between August 2017 and December 2020 including 48 patients (14 HPV-induced: HPV+ and 34 non-HPV-induced: HPV-) with oropharyngeal squamous cell carcinoma treated by radiotherapy±chemotherapy (RT/CT). Nutritional risk at the time of tumor assessment (TA) was assessed by weight loss, swallowing ability, and the presence of digestive disorders in 4 stages of increasing severity. Nutritional status was assessed by weight and nutrition risk index (NRI) at the time of TA, before the start and at 3 months from the end of RT±CT. During RT±CT, the NRI and the systemic inflammatory response index (SIRI=neutrophils * monocytes/lymphocytes) were assessed weekly.

RESULTS

HPV+patients were at lower nutritional risk at TA (50% grade ≥2 vs 85%, P=0.02), lost more weight (6% of their body weight vs 3%, P=0.05), and increased their SIRI by 7.5 points more than HPV- patients (P=0.04) during RT/CT.

CONCLUSION

HPV+ oropharyngeal cancer patients are at high nutritional risk even in the absence of undernutrition at the outset of management.

Malnutrition, Cancer Stage and Gastrostomy Timing as Markers of Poor Outcomes in Gastrostomy-Fed Head and Neck Cancer Patients

For percutaneous endoscopic gastrostomy (PEG)-fed head and neck cancer (HNC) patients, risk markers of poor outcomes may identify those needing more intensive support. This retrospective study aimed to evaluate markers of poor outcomes using TNM-defined stages, initial anthropometry [body mass index (BMI), mid-upper arm circumference (MUAC), tricipital skinfold (TSF), mid-arm muscle circumference (MAMC)] and laboratory data (albumin, transferrin, cholesterol), with 138 patients, 42-94 years old, enrolled. The patients had cancer, most frequently in the larynx (n = 52), predominantly stage IV (n = 109). Stage IVc presented a four times greater death risk than stage I (OR 3.998). Most patients presented low parameters: low BMI (n = 76), MUAC (n = 114), TSF (n = 58), MAMC (n = 81), albumin (n = 47), transferrin (n = 93), and cholesterol (n = 53). In stages I, III, IVa, and IVb, MAMC and PEG-timing were major survival determinants. Each MAMC unit increase resulted in 16% death risk decrease. Additional 10 PEG-feeding days resulted in 1% mortality decrease. Comparing IVa/IVb vs. IVc, albumin and transferrin presented significant differences (p = 0.042; p = 0.008). All parameters decreased as severity of stages increased. HNC patients were malnourished before PEG, with advanced cancer stages, and poor outcomes. Initial MAMC, reflecting lean tissue, significantly increases survival time, highlighting the importance of preserving muscle mass. PEG duration correlated positively with increased survival, lowering death risk by 1% for every additional 10 PEG-feeding days, signaling the need for early gastrostomy.

Current research trends, hotspots, and frontiers of medical nutrition therapy on cancer: a bibliometric analysis

Background

There is a high prevalence of malnutrition in cancer patients, which seriously affects the anti-cancer therapy effect and outcomes, causing a huge disease burden worldwide. Appropriate nutritional support is important for cancer prevention and control. The aim of this study was to explore the development trends, hotspots, and frontiers of Medical Nutrition Therapy (MNT) on Cancer from a bibliometric perspective, and provide new insights for future research and clinic practices.

Methods

The global literature of MNT on Cancer published between 1975 and 2022 were searched in the Web of Science Core Collection Database (WOSCC). After refining the data, descriptive analysis and data visualization were performed with bibliometric tools (CiteSpace, VOSviewer, and R package "bibliometrix").

Results

A total of 10,339 documents with a timespan from 1982 to 2022 were included in this study. The number of documents had increased continuously over the past 40 years, especially with a steep rise from 2016 to 2022. The majority of scientific production outputs were from the United States, which had the most core research institutions and authors. The published documents could be clustered into three themes respectively labeled by terms "double-blind", "cancer" and "quality-of-life". "gastric cancer", "outcome", "inflammation", "sarcopenia" and "exercise" were the most prominent keywords in recent years. "breast-cancer", "colorectal-cancer", "expression", "risk", "in-vitro", "quality-of-life", "cancer" and "life" might represent the newly emerged topics.

Conclusions

There were a good research foundation and reasonable disciplinary structure in the field of medical nutrition therapy for cancer at present. The core research team was mainly located in the United States, England, and other developed countries. According to the current trends in publications, more articles shall be published in the future. Nutritional metabolism, malnutrition risk, and the impact of nutritional therapy on prognosis might be research hotspots. In particular, it was important to focus on specific cancer, such as breast cancer, colorectal cancer, and gastric cancer, which might be the frontiers.

The impact of nutritional status in nivolumab-treated patients with advanced esophageal cancer

Although phase III trials have reported improved overall survival in patients with advanced esophageal squamous cell carcinoma following treatment with nivolumab, as compared with chemotherapy (paclitaxel or docetaxel), the treatment was effective only in a limited number of patients. Therefore, the aim of this study is to determine whether there is a correlation between nutritional status (Glasgow prognostic score, prognostic nutritional index, and neutrophil-to-lymphocyte ratio) and prognosis of advanced esophageal cancer in patients treated with taxane or nivolumab therapy. The medical records of 35 patients who received taxane monotherapy (paclitaxel or docetaxel), for advanced esophageal cancer between October 2016 and November 2018 (taxane cohort) were reviewed. The clinical data of 37 patients who received nivolumab therapy between March 2020 and September 2021 (nivolumab cohort) were collected. The median overall survival was 9.1 months for the taxane cohort and 12.5 months for the nivolumab cohort. In the nivolumab cohort, patients with good nutritional status had significantly better median overall survival than those with poor nutritional status (18.1 vs. 7.6 months, respectively, p = 0.009, classified by prognostic nutritional index, 15.5 vs. 4.3 months, respectively, p = 0.012, classified by Glasgow prognostic score), whereas the prognosis of the patients treated with taxane therapy was less affected by the nutritional status. This suggests that the pretreatment nutritional status of patients with advanced esophageal cancer is a key factor for successful outcomes, especially for treatment with nivolumab.

A new era for optic pathway glioma: A developmental brain tumor with life-long health consequences

Optic pathway and hypothalamic glioma (OPHG) are low-grade brain tumors that arise from any part of the visual pathways frequently involving the hypothalamus. The tumors grow slowly and present with features driven by their precise anatomical site, their age at presentation and the stage of growth and development of the host neural and orbital bony tissues. Up to 50% of optic pathway glioma arise in association with Neurofibromatosis type 1 (NF1), which affects 1 in 3,000 births and is a cancer predisposition syndrome. As low-grade tumors, they almost never transform to malignant glioma yet they can threaten life when they present under two years of age. The main risks are to threaten vision loss by progressive tumor damage to optic pathways; furthermore, invasion of the hypothalamus can lead to diencephalic syndrome in infancy and hypopituitarism later in life. Progressive cognitive and behavioural dysfunction can occur, as part of NF1 syndromic features and in sporadic cases where large bulky tumors compress adjacent structures and disrupt neuro-hypothalamic pathways. Persistently progressive tumors require repeated treatments to attempt to control vision loss, other focal brain injury or endocrine dysfunction. In contrast tumors presenting later in childhood can be seen to spontaneously arrest in growth and subsequently progress after periods of stability. These patterns are influenced by NF status as well as stages of growth and development of host tissues. The past two decades has seen an expansion in our understanding and knowledge of the clinical and scientific features of these tumors, their modes of presentation, the need for careful visual and endocrine assessment. This influences the decision-making surrounding clinical management with surgery, radiotherapy, chemotherapy and most recently, the potential benefit of molecularly targeted drug therapy. This article, based upon the authors' clinical and research experience and the published literature will highlight advances in approach to diagnosis, the established role of vision loss as justification of treatments and the emerging evidence of endocrine and neurological consequences that need to be incorporated into judgements for case selection for therapy or observation. Consideration is given to the current state of biological evidence justifying current trials of new therapies, the genetic studies of the NF1 gene and the potential for new approaches to OPHG detection and treatment. The outstanding health system priorities from the perspective of children, their parents and health system commissioners or insurers are discussed.

Präoperatives Ernährungsmanagement in der großen Tumorchirurgie des Bauchraumes an deutschen Kliniken. Eine explorative Strukturanalyse

Bis zu 80% der PatientInnen vor Tumorresektionen des oberen Gastrointestinaltrakts sind mangelernährt. Dabei hat schon der präoperative Ernährungszustand einen signifikanten Einfluss auf den perioperativen Verlauf. Ein adäquater präoperativer Ernährungszustand, der unter anderem die Komplikationsrate und die Krankenhausliegedauer reduzieren kann, ist daher erstrebenswert. Zwar empfehlen einschlägige Leitlinien Maßnahmen zur Erkennung und Behandlung einer Mangelernährung, jedoch fehlt es bislang an Vorschlägen zur Planung eines strukturieren präoperativen Ernährungsmanagements auf die BehandlerInnen zurückgreifen können. Innerhalb dieser Arbeit wurden 40 Krankenhäuser in Deutschland deshalb zu individuell vorhandenen Strukturen und Maßnahmen zum präoperativen Ernährungsmanagement von PatientInnen vor Tumorresektionen des oberen Gastrointestinaltrakts befragt. Die Befragungen zeigen, dass Maßnahmen zur Erkennung und Therapie einer präoperativen Mangelernährung mehrheitlich bekannt und akzeptiert sind. So befürworten 35 der 40 TeilnehmerInnen eine präoperative Ernährungstherapie bei mangelernährten PatientInnen, 26 TeilnehmerInnen erwägen hierfür sogar einen Aufschub der Operation. Eine flächendeckende Umsetzung an den Kliniken scheitere jedoch häufig an Hinderungsgründen, wie fehlender Sichtbarkeit der Ernährung als Therapiebaustein unter BehandlerInnen, labilen Verantwortlichkeiten sowie unzureichenden finanziellen und personellen Ressourcen. Mögliche Lösungsvorschläge zum Abbau der Hindernisse reichen von Refinanzierungsmöglichkeiten der klinischen Ernährungstherapie bis hin zu Forderungen auf gesundheitspolitischer Ebene. Aus den Erkenntnissen aktueller Studien und Leitlinien, sowie den Ergebnissen der Befragung, unterbreitet diese Arbeit einen Vorschlag zur Implementierung eines präoperativen Ernährungsmanagements. Dessen Umsetzbarkeit im klinischen Alltag sollte dabei durch wissenschaftliche Verfahren begleitet werden.

Adherence to Mediterranean Diet and Nutritional Status in Women with Breast Cancer: What Is Their Impact on Disease Progression and Recurrence-Free Patients' Survival?

Introduction: Nutritional status impacts the survival of patients with cancer. There are few studies that investigate the role of nutritional status on breast cancer survival in women with breast cancer, and even fewer regarding the impact of adhering to the Mediterranean diet (MD). The present study aims to assess the nutritional status, MD adherence, physical activity levels and health-related quality of life (HRQOL) in women diagnosed with breast cancer and evaluate these parameters regarding recurrence-free survival. Methods: A total of 114 women, aged 35-87 years old, diagnosed with breast cancer in Larissa, Greece, participated in the study. Tumor histopathology was reported, and anthropometric indices were measured by a trained nurse, while questionnaires regarding nutritional status (via mini nutritional assessment), HRQOL via EORTC QLQ-C30, physical activity levels via IPAQ and Mediterranean diet adherence via MedDietScore were administered. The participants were followed-up for a maximum time interval of 42 months or until recurrence occurred. Results: A total of 74% of patients were overweight or obese, while 4% of women were undernourished, and 28% were at risk of malnutrition. After 42 months of follow-up, 22 patients (19.3%) had relapsed. The median time to recurrence was 38 months (IQR: 33-40 months) and ranged between 23 to 42 months. Higher levels of MD adherence were significantly associated with lower body mass index (BMI) values, earlier disease stage, smaller tumor size, absence of lymph node metastases and better physical activity levels (p < 0.05). Normal nutritional status was significantly associated with higher BMI values and better health-related quality of life (p ≤ 0.05). In univariate analysis, patients with higher levels of MD adherence and well-nourished patients had significantly longer recurrence-free survival (p < 0.05). In multivariate analysis, MD adherence and nutritional status were independently associated with recurrence-free patients' survival after adjustment for several confounding factors (p < 0.05). Conclusions: The impact of MD on time to recurrence is still under investigation, and future interventional studies need to focus on the role of adhering to the MD before and after therapy in survival and breast cancer progression. Furthermore, the present study also highlights the importance of an adequate nutritional status on disease progression, and the need for nutritional assessment, education and intervention in women with breast cancer.

Monitoring energy balance through clinical and serum biomarkers in patients with hematologic malignancies undergoing chemotherapy

Despite widespread concern about energy imbalance due to tumor and chemotherapy-related side effects, little is known about detailed variations in energy input, metabolic rate, and physical activity. This study explored changes in energy balance components and serum biomarkers of patients with hematologic malignancies undergoing chemotherapy. Our prospective study included 40 patients with hematologic malignancies hospitalized for chemotherapy. We measured energy balance components, physical function, and serum biomarkers at baseline and weekly after chemotherapy for 3 weeks. Significant weight loss, representing negative energy balance, occurred at 2 (p = 0.002) and 3 weeks (p < 0.001) post-chemotherapy. Statistically reduced oral intake was observed at 3 weeks post-chemotherapy (p = 0.040), and resting energy expenditure statistically decreased according to Harris-Benedict equation, but not to Penn State University equation. Physical function according to DEMMI score decreased significantly at 3 weeks post-chemotherapy (p = 0.002). Serum biomarker analysis demonstrated significant changes in albumin, total protein, CXCL13, and GDF15, with exception of leptin. Although conventional serum biomarkers (total protein and albumin) did not reach pathological states despite their statistical differences, subgroup analysis showed CXCL13 in weight loss group and GDF15 in reduced oral intake group were significantly changed. Over half of patients (65.0%, n = 26) suffered from energy imbalance associated with weight loss and reduced oral intake during chemotherapy. Serial laboratory results suggested that novel biomarkers (CXCL13, GDF15) could be correlated with cachexic state and reduced food intake. Monitoring clinical and serum biomarkers associated with energy balance together can help identify needs for nutritional support in patients with hematologic malignancies undergoing chemotherapy.

Cancer cachexia: a nutritional or a systemic inflammatory syndrome?

Cancer cachexia has long been perceived as a nutritional syndrome. However, nutritional interventions have continued to be ineffective. With the recent recognition of the importance of systemic inflammation in the definition of this syndrome and treatment, has the time come to consider whether this syndrome is primarily a manifestation of systemic inflammation with the consequent implications for future treatment?

When is enteral nutrition indicated?

Enteral nutrition (EN) is a vital component of nutrition around the world. EN allows for delivery of nutrients to those who cannot maintain adequate nutrition by oral intake alone. Common questions regarding EN are when to initiate and in what scenarios it is safe. The answers to these questions are often complex and require an evidence-based approach. The Board of Directors of the American Society for Parenteral and Enteral Nutrition (ASPEN) established an Enteral Nutrition Committtee to address the important questions surrounding the indications for EN. Consensus recommendations were established based on eight extremely clinically relevant questions regarding EN indications as deemed by the Enteral Nutrition Committee. These consensus recommendations may act as a guide for clinicians and stakeholders on difficult questions pertaining to indications for EN. This paper was approved by the ASPEN Board of Directors.

Examining the Benefits of Digitally Selectable Meals Called "À La Carte Digital-Select" in Cancer Chemotherapy Patients

We explored the benefits of a digitized bedside terminal with a touchscreen for selectable hospital meals called “à la carte digital-select” in cancer chemotherapy patients. The subjects used “à la carte digital-select” for 35 days, from November to December 2015. On average, 253 (between 196 and 288) patients accessed this system per day, and 40 patients used it daily (15.9%). Subjects included 75 patients (cancer chemotherapy: chem-digital-select patients, female: 47) and 12 patients (concurrent chemo radiotherapy: CRT-digital-select patients, female: 6) with a repeat rate of 87% (65) and 100% (12). The average length of hospital stay in chem-digital-select patients was 6 days (1-35), the average number of days using “à la carte digital-select” was 3 days (1-24); a correlation was observed between these factors (r = .80; P < .01). The eating rate of chemotherapy patients and CRT-digital-select patients was high (81%, 81%), and no differences were observed between the rate in the cisplatin group (80%) with 28 patients, the non-cisplatin group (81%) with 47 patients, CRT-digital-select patients (81%) with 12 patients (P = .59; ANOVA). Registered dietitians provided no nutritional intervention in any of the cases. We found that “à la carte digital-select” can contribute to supporting cancer chemotherapy and the dietary needs of cancer patients undergoing chemotherapy.

Nutritional status and quality of life in adults undergoing allogeneic hematopoietic stem cell transplantation

Although the effects of malnutrition on morbidity and mortality in adult patients undergoing allogeneic hematopoietic stem cell transplantation are clear, the relationship with quality of life (QOL) is less clear. The purpose of this study was to assess the relationship between malnutrition and QOL. A prospective observational study was conducted in 36 adult patients undergoing allogeneic hematopoietic stem cell transplantation. Adapted criteria of the Global Leadership Initiative on malnutrition have been used for the diagnosis of malnutrition in clinical settings. A cancer linear analog scale was used to assess QOL. Overall QOL at 14 days after allogeneic hematopoietic stem cell transplantation was 37.1 (95% CI 2.9–45.39) in patients without severe malnutrition, versus 16.0 (95% CI − 6.6 to 38.6) in patients with severe malnutrition (p = 0.05). At discharge, it was 48.0 (95% CI 38.4–57.6) versus 34.0 (95% CI 4.1–63.9) (p = 0.27). The results of our study suggest that patients with severe malnutrition at discharge tend to have worse QOL. A larger cohort of patients is required to confirm this hypothesis.

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.

Effects of Enteral Nutrition on Patients With Oesophageal Carcinoma Treated With Concurrent Chemoradiotherapy: A Prospective, Multicentre, Randomised, Controlled Study

Background

The oesophageal carcinoma patients show high incidence of malnutrition, which negatively affects their therapy outcome. Moreover, benefits of enteral nutrition remain to be studied in details in these patients. Therefore, we set to assess the effects of enteral nutrition on the nutritional status, treatment toxicities and survival in the oesophageal carcinoma patients treated with concurrent chemoradiotherapy (CCRT).

Materials and Methods

Eligible patients were randomly assigned to either the experimental or control group. The patients in the experimental group were treated with a whole-course enteral nutrition management, while the control group were provided a unsystematic nutrition without setting intake goals for energy and protein. The primary endpoint was a change in body weight, while the secondary endpoints included nutrition-related haematological indicators, toxicities, completion rate of treatment and survival.

Results

A total of 222 patients were randomised to either the experimental (n=148) or control (n=74) group. Patients in the experimental group showed significantly less decrease in body weight, serum albumin and haemoglobin levels, a lower incidence rates of grade ≥3 myelosuppression and infection, and a higher completion rate of CCRT than those in the control group. While analyses of the 2 and 3 year overall survival (OS) and progression-free survival (PFS) did not reveal differences between these groups, we observed a significantly higher OS at 1 year (83.6% vs. 70.0%). In the subgroup analysis, patients with patient-generated subjective global assessment (PG-SGA)=C were likely to have better OS and PFS with enteral nutrition.

Conclusions

In EC patients treated with CCRT, enteral nutrition conferred positive effects on the nutritional status, treatment toxicities and prognosis, which mandate its inclusion in clinical practice.

Clinical Trial Registration

This prospective trial has been registered with www.clinicaltrials.gov as NCT02399306.

Tube feeding in head and neck cancer patients undergoing chemoradiotherapy: a systematic review

BACKGROUND

Head and neck cancer patients are frequently malnourished at the time of diagnosis and prior to the beginning of treatment. In addition, chemo-radiotherapy (CRT) causes or exacerbates symptoms, such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea, and vomiting, with consequent worsening of malnutrition. If obstructing cancer and/or mucositis interfere with swallowing, enteral nutrition should be delivered by a nasogastric tube (NGT) or percutaneous endoscopic gastrostomy (PEG).

AIM

To revise the studies comparing NGT and PEG in terms of nutritional outcomes, survival, hospitalizations, number of interruptions of radiotherapy, quality of life, swallowing function.

RESULTS

A total of 250 publications were identified via electronic databases. After screening the titles, abstracts and full texts, 26 manuscripts that met the inclusion criteria were included for analysis. We divided the analysis in two sections: 1) comparison of enteral nutrition through NGT or PEG and 2) comparison of reactive PEG (R-PEG) and prophylactic PEG (P-PEG).

RESULTS

Both PEG and NGT are an effective method of providing nutritional support during chemoradiotherapy for head and neck cancer. They are essentially comparable in terms of nutritional outcomes, number of radiotherapy interruptions, survival, and quality of life, whereas swallow function seems better with NGT. PEG may be associated with major complications such as exit site infection, malfunction, leakage, pain, and pulmonary infection and higher costs. Nevertheless, NGT dislodged more often, patients find it more inconvenient, may cause aspiration pneumonia and PEG has advantages over NGT of enhanced mobility and improved cosmesis. P-PEG and R-PEG are essentially similar in terms of nutritional outcomes, number of interruptions of radiotherapy, and survival. Conflicting results have been reported about quality of life.

CONCLUSION

PEG is not better than NGT in terms of nutritional, oncologic, and quality of life outcomes. Prophylactic feeding through NGT or PEG, compared to reactive feeding, does not offer significant advantages in terms of nutritional outcomes, interruptions of radiotherapy and survival. However, the number of prospective randomized studies on this topic is much limited and consequently definitive conclusions cannot be drawn. Overall, it seems that further adequate prospective, randomized studies are needed to define the better nutritional intervention in head and neck cancer patients undergoing chemoradiotherapy.

The Difficult Decision Not to Prescribe Artificial Nutrition by Health Professionals and Family: Bioethical Aspects

Introduction

Bioethics and nutrition are essential issues in end of life, advanced dementia, life-sustaining therapies, permanent vegetative status, and unacceptably minimal quality of life. Even though artificially administered nutrition (AAN), for this type of health condition, does not improve quality of life and extension of life, and there is evidence of complications (pulmonary and gastrointestinal), it has been used frequently. It had been easier considering cardiopulmonary resuscitation as an ineffective treatment than AAN for a healthy team and/or family. For this reason, many times, this issue has been forgotten.

Objectives

This study aimed to discuss bioethical principles and AAN in the involved patients.

Discussion

The AAN has been an essential source of ethical concern and controversy. There is a conceptual doubt about AAN be or not be a medical treatment. It would be a form of nourishment, which constitutes primary care. These principles should be used to guide the decision-making of healthcare professionals in collaboration with patients and their surrogates.

Conclusions

This difficult decision about whether or not to prescribe AAN in patients with a poor prognosis and without benefits should be based on discussions with the bioethics committee, encouraging the use of advanced directives, education, and support for the patient, family, and health team, in addition to the establishment of effective protocols on the subject. All of this would benefit the most important person in this process, the patient.

The impact of nutritional status on pancreatic cancer therapy

INTRODUCTION

Pancreatic Ductal Adenocarcinoma (PDAC) is an aggressive disease with poor outcomes. One of the reasons for the dismal prognosis resides in its impressive ability to alter the nutritional status of patients who develop malnutrition, cachexia, anorexia, and sarcopenia in most cases. The ideal way to measure such changes in PDAC patients, in order to readily identify them and avoid complications or discontinuations of treatment is a relatively unexplored area. In addition, most PDAC patients experience pancreatic exocrine insufficiency (PEI) that contributes to the complex puzzle of malnutrition and that can be treated with Pancreatic Enzyme Replacement Therapy (PERT).

AREAS COVERED

We review current knowledge on the impact of nutritional status on both surgical and medical treatments for PDAC, reporting available data on the causes of malnutrition, characteristics, and advantages of different tools to investigate nutritional status and possible strategies to improve patient outcomes.

EXPERT OPINION

All PDAC patients should receive a careful nutritional assessment at diagnosis, and this should be repeated alongside their treatment path. Screening tools and biochemical variables or scores are associated with prognosis, but bioimpedance vector analysis (BIVA) and radiological assessment of body composition seem more accurate in predicting clinical outcomes and postoperative complications.

Nutritional status disorders and methods of their correction in patients with advanced pancreatic cancer

Despite of achieved progress in advanced pancreatic cancer treatment, the disease outcomes remain far from satisfying. The peculiarity of malnutrition treatment in these patients is the result of its causes complexity and progressively growing manifestations extent. The review represents mechanisms of malnutrition and approaches to their treatment.

Pancreatic Cancer and Gut Microbiome-Related Aspects: A Comprehensive Review and Dietary Recommendations

Gut microbiota plays a significant role in the human body providing many beneficial effects on the host. However, its dysbiotic alterations may affect the tumorigenic pathway and then trigger the development of pancreatic cancer. This dysbiosis can also modulate the aggressiveness of the tumor, influencing the microenvironment. Because pancreatic cancer is still one of the most lethal cancers worldwide with surgery as the only method that influences prognosis and has curative potential, there is a need to search for other strategies which will enhance the efficiency of standard therapy and improve patients' quality of life. The administration of prebiotics, probiotics, next-generation probiotics (Faecalibacterium prausnitzii, Akkermansia muciniphila), synbiotics, postbiotics, and fecal microbiota transplantation through multiple mechanisms affects the composition of the gut microbiota and may restore its balance. Despite limited data, some studies indicate that the aforementioned methods may allow to achieve better effect of pancreatic cancer treatment and improve therapeutic strategies for pancreatic cancer patients.

Identifying Knowledge and Practices regarding Cancer Patient Malnutrition: A Survey Study among Oncologists

Malnutrition is one of the most common complications of cancer and its treatments with a prevalence of up to 80% among cancer patients. Thus, standardized and target-oriented attitudes of oncologists toward nutritional management are particularly important. This study aims to report the questionnaire-based evaluation of different views toward medical nutrition among medical and radiation oncologists with the purpose to underline the problems and requirements of cancer nutrition. A national web-based survey composed of 26 multiple choice questions about participant demographics, level of knowledge about cancer nutrition, and approaches to malnutrition were completed by 247 oncologists. The survey was answered by a total of 247 (34%) radiation and medical oncologists. The majority of the oncologists (77%) were working at the University Hospitals and Education & Research Hospitals. Most of them were specialists with 5-10 years of experience. Nutritional status was routinely assessed in oncology units of 84% of (206) oncologists. However, only 50% reported nutritional evaluation follow-ups without waiting for a patient's declaration and 5 (2%) oncologists reported the absence of nutritional evaluation in their unit. Additionally, more than 79% of participants reported that their knowledge was not enough about enteral and parenteral nutrition while 8% were skeptical about the benefits of medical nutrition. Although the role of nutrition as an essential part of cancer care is widely recognized, the availability of limited high-quality evidence, problems of accessibility, lack of routine nutritional evaluation, and varying indicators for malnutrition are some of the problems preventing standardized nutritional management. Therefore, there are a variety of approaches and barriers to the implementation of guidelines. Further studies are needed to identify areas of improvement, as well as strategies to implement nutritional therapy in cancer care.

Clinical characteristics and pathogens in percutaneous endoscopic gastrostomy site infection in patients with head and neck cancer: A 16-year retrospective study

OBJECTIVES

Wound infection is the most common complication associated with percutaneous endoscopic gastrostomy (PEG) placement, with an incidence between 4% and 30%. In this study, we compared the characteristics of PEG site infection between the head and neck cancer (HNC) group and the non-HNC group.

METHODS

This study was conducted at Kangdong Sacred Heart Hospital at the Ilsong Head and Neck Cancer Center. We retrospectively collected and analyzed data on patients who underwent PEG insertion from October 2003 to May 2019 to evaluate the risk factors and microbiological etiologies of PEG site infection.

RESULTS

A total of 316 (HNC group [n = 129] and non-HNC group [n = 187]) patients undergoing PEG insertion were included in this study. Moreover, 67 episodes of PEG site infection were diagnosed, with an overall prevalence of 21.2%. PEG site infections were significantly higher in the HNC group than in the non-HNC group (32.6% vs 13.4%, P <.001). Pseudomonas aeruginosa is the most common pathogen associated with a PEG site infection. Multidrug-resistant (MDR) P aeruginosa was more frequent in the HNC group than in the non-HNC group (78.6% vs 25.0%, P = .006).

CONCLUSIONS

For appropriate treatment, P aeruginosa, especially MDR P aeruginosa, should be considered when selecting empirical antibiotics for PEG site infection in patients with HNC.Level of Evidence: 4.

Nutritional support practices and opinions toward gastrostomy use in pediatric bone marrow transplant centers: A national survey

OBJECTIVE

Previous surveys have shown deviations in nutritional practices from international guidelines during bone marrow transplant (BMT). Guidelines recommend enteral nutrition first-line and nasogastric tubes are the mainstay for its provision. Gastrostomies provide an alternative, yet their use is less common. This national survey investigated nutrition support practices in pediatric allogeneic BMT centers and compared clinicians' opinions on gastrostomy use. The aim of this study was to identify the national picture of nutritional support practices across pediatric allogeneic BMT centers, including use and opinions of dietitians, clinical nurse specialists, and physicians, toward gastrostomy feeding.

METHODS

An online survey was administered to 12 centers. The lead dietitian answered questions regarding nutritional counseling, screening, assessment, and interventions. Questions regarding current use, perceived advantages, and problems of gastrostomies were answered by the dietitian, lead clinical nurse specialist, and physician.

RESULTS

A 100% response rate was achieved from 12 centers (N = 36 clinicians). Nutritional counseling was provided in 92% of centers before and routinely throughout admission, 83% screened on and regularly throughout admission, 83% assessed nutritional status before transplant, and 92% used enteral nutrition first-line. Forty-two percent of the centers used gastrostomies. In those not using gastrostomies, 76% of clinicians felt some children should be offered a gastrostomy. Clinicians perceived less displacements (78%) and cosmetic appearance (69%) as the most common advantages of gastrostomies over nasogastric tubes. Risks associated with surgery (92%) and tube/stoma complications (58%) were the most common perceived problems.

CONCLUSIONS

A similar approach was shown on many aspects of nutritional support. Gastrostomy use divided opinion with differences in use and perceived advantages, but agreement on potential complications. Despite their risks, clinicians wanted to use gastrostomies more. Placement requires careful consideration of the risks, benefits, and family preferences.

Development and external validation of a prediction model for tube feeding dependency for at least four weeks during chemoradiotherapy for head and neck cancer

BACKGROUND & AIMS

Patients who receive chemoradiotherapy or bioradiotherapy (CRT/BRT) for locally advanced head and neck squamous cell carcinoma (LAHNSCC) often experience high toxicity rates interfering with oral intake, causing tube feeding (TF) dependency. International guidelines recommend gastrostomy insertion when the expected use of TF exceeds 4 weeks. We aimed to develop and externally validate a prediction model to identify patients who need TF ≥ 4 weeks and would benefit from prophylactic gastrostomy insertion.

METHODS

A retrospective multicenter cohort study was performed in four tertiary head and neck cancer centers in the Netherlands. The prediction model was developed using data from University Medical Center Utrecht and the Netherlands Cancer Institute and externally validated using data from Maastricht University Medical Center and Radboud University Medical Center. The primary endpoint was TF dependency ≥4 weeks initiated during CRT/BRT or within 30 days after CRT/BRT completion. Potential predictors were extracted from electronic health records and radiotherapy dose-volume parameters were calculated.

RESULTS

The developmental and validation cohort included 409 and 334 patients respectively. Multivariable analysis showed predictive value for pretreatment weight change, texture modified diet at baseline, ECOG performance status, tumor site, N classification, mean radiation dose to the contralateral parotid gland and oral cavity. The area under the receiver operating characteristics curve for this model was 0.73 and after external validation 0.62. Positive and negative predictive value for a risk of 90% or higher for TF dependency ≥4 weeks were 81.8% and 42.3% respectively.

CONCLUSIONS

We developed and externally validated a prediction model to estimate TF-dependency ≥4 weeks in LAHNSCC patients treated with CRT/BRT. This model can be used to guide personalized decision-making on prophylactic gastrostomy insertion in clinical practice.

ESPEN practical guideline: Home enteral nutrition

This ESPEN practical guideline will inform physicians, nurses, dieticians, pharmacists, caregivers and other home enteral nutrition (HEN) providers in a concise way about the indications and contraindications for HEN, as well as its implementation and monitoring. This guideline will also inform interested patients requiring HEN. Home parenteral nutrition is not included but will be addressed in a separate ESPEN guideline. The guideline is based on the ESPEN scientific guideline published before, which consists of 61 recommendations that have been reproduced and renumbered, along with the associated commentaries that have been shorted compared to the scientific guideline. Evidence grades and consensus levels are indicated. The guideline was commissioned and financially supported by ESPEN and the members of the guideline group were selected by ESPEN.

Comparison of Preoperative Nutritional Indexes for Outcomes after Primary Esophageal Surgery for Esophageal Squamous Cell Carcinoma

BACKGROUND

This study aimed to compare the controlling nutritional status (CONUT) score, prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI) for predicting postoperative outcomes in patients with esophageal squamous cell carcinoma undergoing esophagectomy.

METHODS

We retrospectively reviewed the data of 1265 consecutive patients who underwent elective esophageal surgery. The patients were classified into no risk, low-risk, moderate-risk, and high-risk groups based on nutritional scores.

RESULTS

The moderate-risk (hazard ratio [HR]: 1.55, 95% confidence interval [CI]: 1.24-1.92, p < 0.001 in CONUT; HR: 1.61, 95% CI: 1.22-2.12, p = 0.001 in GNRI; HR: 1.65, 95% CI: 1.20-2.26, p = 0.002 in PNI) and high-risk groups (HR: 1.91, 95% CI: 1.47-2.48, p < 0.001 in CONUT; HR: 2.54, 95% CI: 1.64-3.93, p < 0.001 in GNRI; HR: 2.32, 95% CI: 1.77-3.06, p < 0.001 in PNI) exhibited significantly worse 5-year overall survival (OS) compared with the no-risk group. As the nutritional status worsened, the trend in the OS rates decreased (p for trend in all indexes < 0.05).

CONCLUSIONS

Malnutrition, evaluated by any of three nutritional indexes, was an independent prognostic factor for postoperative survival.
