Evaluation of Nutritional Status in Cancer Patients Receiving Radiotherapy

Skeletal Muscle Segmentation at the Level of the Third Lumbar Vertebra (L3) in Low-Dose Computed Tomography: A Lightweight Algorithm

BACKGROUND

The cross-sectional area of skeletal muscles at the level of the third lumbar vertebra (L3) measured from computed tomography (CT) images is an established imaging biomarker used to assess patients' nutritional status. With the increasing prevalence of low-dose CT scans in clinical practice, accurate and automated skeletal muscle segmentation at the L3 level in low-dose CT images has become an issue to address. This study proposed a lightweight algorithm for automated segmentation of skeletal muscles at the L3 level in low-dose CT images.

METHODS

This study included 57 patients with rectal cancer, with both low-dose plain and contrast-enhanced pelvic CT image series acquired using a radiotherapy CT scanner. A training set of 30 randomly selected patients was used to develop a lightweight segmentation algorithm, and the other 27 patients were used as the test set. A radiologist selected the most representative axial CT image at the L3 level for both the image series for all the patients, and three groups of observers manually annotated the skeletal muscles in the 54 CT images of the test set as the gold standard. The performance of the proposed algorithm was evaluated in terms of the Dice similarity coefficient (DSC), precision, recall, 95th percentile of the Hausdorff distance (HD95), and average surface distance (ASD). The running time of the proposed algorithm was recorded. An open source deep learning-based AutoMATICA algorithm was compared with the proposed algorithm. The inter-observer variations were also used as the reference.

RESULTS

The DSC, precision, recall, HD95, ASD, and running time were 93.2 ± 1.9% (mean ± standard deviation), 96.7 ± 2.9%, 90.0 ± 2.9%, 4.8 ± 1.3 mm, 0.8 ± 0.2 mm, and 303 ± 43 ms (on CPU) for the proposed algorithm, and 94.1 ± 4.1%, 92.7 ± 5.5%, 95.7 ± 4.0%, 7.4 ± 5.7 mm, 0.9 ± 0.6 mm, and 448 ± 40 ms (on GPU) for AutoMATICA, respectively. The differences between the proposed algorithm and the inter-observer reference were 4.7%, 1.2%, 7.9%, 3.2 mm, and 0.6 mm, respectively, for the averaged DSC, precision, recall, HD95, and ASD.

CONCLUSION

The proposed algorithm can be used to segment skeletal muscles at the L3 level in either the plain or enhanced low-dose CT images.

Multidisciplinary survey on use of feeding tubes in head and neck cancer patients undergoing chemoradiotherapy in Germany-the SUFEETUBE project

BACKGROUND AND OBJECTIVE

Data on enteral tube feeding in head and neck cancer (HNC) patients undergoing chemoradiotherapy vary considerably between German institutions. This survey aims to investigate the management of feeding tubes in an interdisciplinary context across Germany.

MATERIALS AND METHODS

Between December 2022 and May 2023, 70 participants (42 radiation oncologists, 12 medical oncologists, 14 head and neck surgeons, and 2 physicians covering several specialties) responded to our web-based survey. In addition to the type of institution (university hospital, private practice, etc.), their age, and professional experience (in years), participants were asked several questions on the indication and institutional policy for tube placement and management (prophylactic/reactive nasogastric or gastrostomy tube). All questions were mandatory single- or multiple-choice questions, while additional comments were possible by email.

RESULTS

Most participants were employed at a university hospital (n = 52; 74.3%) and came from a radiation oncology background (n = 42; 60%). Fifty-four contributors (77.1%) reported that no nutritional risk screening prior to chemoradiotherapy was routinely performed, and 71.4% (n = 50) stated that no standardized protocol was used at the institution to set the indication for tube placement. Generally, policies and methods of tube feeding vary considerably between the individual institutions and specialties. However, the majority (n = 56, 80%) recommended a prophylactic percutaneous enteral gastrostomy (PEG) tube to their patients before chemoradiotherapy. Still, there was no consistent trend regarding the approach for reactive tube feeding.

CONCLUSION

The policies and methods of tube feeding vary considerably between the individual institutions and specialties in Germany. In the era of individualized medicine, uniform protocols are difficult to establish. However, a baseline nutritional risk screening could simplify decision-making in clinical practice.

Cachexia and head and neck squamous cell carcinoma: A scoping review

OBJECTIVE

The objective of this paper was to provide an understanding of cachexia in relation to oral squamous cell carcinoma relevant to oral health care. The paper is a scoping review of aspects of the clinical presentation, aetiology and management of cachexia in relation to oral health and oral health care.

METHODS

A combined search of MEDLINE and EMBASE databases (via OVID) was conducted using the terms ([Head and Neck] OR [Oral Squamous Cell Carcinoma]) AND (Cachexia). Duplicates were removed and results were subsequently limited to studies published between 2000 and 2023, humans and English language. After screening and full-text assessment a total number of 87 studies were included in the review.

RESULTS

It is evident that cachexia is a not uncommon feature of patients with advanced malignancy of the head and neck driven by a multitude of mechanisms, induced by the tumour itself, that lead to reduced nutritional intake, increased metabolism and loss of adipose and skeletal tissue.

CONCLUSION

While a variety of nutritional, physical, psychological and pharmacological interventions may improve quality and duration of life, ultimately the diagnosis of cachexia in relation to head and neck cancer remains an indicator of poor life expectancy.

Risk factors for malnutrition in patients with nasopharyngeal carcinoma

BACKGROUND

Malnutrition is a common complication in patients with nasopharyngeal carcinoma (NPC). However, there are few studies on risk factors for malnutrition in NPC patients. Our aims were to identify the risk factors for malnutrition in NPC patients.

METHODS

NPC patients were recruited in this cross-sectional study, and they were divided into well-nourished and malnourished groups according to the Global Leadership Initiative on Malnutrition (GLIM). Potential risk factors were initially screened using univariate analysis (p < 0.1), and the selected ones were analyzed by logistic regression analysis (p < 0.05) to identify the risk factors for malnutrition in NPC patients.

RESULTS

In total, 305 NPC patients meeting eligibility criteria were enrolled. Multivariate logistic regression analysis revealed that low body mass index (BMI) (OR = 0.596, 95% CI 0.520-0.683, p < 0.001), the high total radiation dose received (OR = 1.046, 95% CI 1.023-1.069, p < 0.001), appetite loss (OR = 2.839, 95% CI 1.269-6.353, p = 0.011), and low PA (OR = 0.993, 95% CI 0.988-0.998, p = 0.008) were risk factors for malnutrition in NPC patients.

CONCLUSIONS

The low BMI, the high total radiation dose received, appetite loss, and low prealbumin were risk factors for malnutrition in NPC patients.

Is Preoperative Serum Albumin Predictive of Adverse Outcomes in Head and Neck Cancer Surgery?

BACKGROUND

Patients with head and neck cancer are at increased risk of malnutrition due to tumor burden and surgical morbidity.

PURPOSE

The purpose of this study was to evaluate the association between preoperative serum albumin and 30-day adverse outcomes in patients undergoing head and neck cancer surgery.

STUDY DESIGN, SETTING, SAMPLE

This was a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database. Patients undergoing an ablative head and neck cancer procedure were included. Patients who had an unclear tumor location based on coding or missing outcome data were excluded.

PREDICTOR VARIABLE

The primary predictor variable was preoperative albumin categorized as low (<3.4 g/dL), intermediate (3.4 to 3.9 g/dL), or high (>3.9 g/dL).

OUTCOME VARIABLE

The primary outcome variable was intensive care unit (ICU)-level complications scored using the Clavien-Dindo classification system. This is a tool used to grade surgical complications, with grade IV and V complications defined as requiring ICU-level care.

COVARIATES

Covariates were demographic (age, sex, body mass index), medical (smoking, functional status, weight loss), and perioperative (concurrent procedures, tumor location, reconstructive modality).

ANALYSES

Descriptive, bivariate, and multiple logistic regression with bootstrap resampling statistics were used to evaluate the association between albumin and adverse outcomes. A significance level of P ≤ .05 was significant.

RESULTS

A total of 4,491 subjects met inclusion criteria and had a documented albumin. There were 435 subjects with low albumin levels, 1,305 with intermediate levels, and 2,751 with high levels. In bivariate analysis, low albumin levels were associated with an increased risk of ICU-level complications, any complication, extended length of stay, and adverse discharge disposition (all P ≤ .001), while high levels were protective (all P ≤ .001). In bootstrapped multivariate analysis using intermediate albumin as the reference group and adjusting for demographics, tumor location, and reconstructive modality among others, low albumin levels were an independent predictor of ICU-level complications (P = .008, odds ratio, 1.64; 95% confidence interval, 1.14 to 2.40), while high levels were protective (P = .014, odds ratio, 0.689; 95% confidence interval, 0.521 to 0.923).

CONCLUSIONS

Preoperative serum albumin was an independent predictor of adverse outcomes following ablative head and neck cancer procedures.

Gastrostomy dependence following pharyngolaryngectomy: The effect of preoperative tube insertion

BACKGROUND

The aim of this study is to investigate the impact of preoperative gastrostomy in patients undergoing pharyngolaryngectomy (PL) on gastrostomy tube dependence at 6 months postoperatively.

METHODS

A retrospective review of patients undergoing PL for laryngeal squamous cell carcinoma between 2005 and 2019 was performed. Parameters were collected and analyzed within the multivariate models.

RESULTS

Ninety-three patients (82% male, mean age 63.4 [SD 9.4]) were included. Preoperative tube placement and pharyngocutaneous fistula (PCF) were associated with an increased likelihood of gastrostomy tube dependence at 6 months (odds ratio 6.43, CI 1.1-38.3, p = 0.041) after adjusting for multiple confounding factors. There was no difference in the incidence of delayed oral feeding, PCF, or hospital stay between the groups.

CONCLUSIONS

Preoperative tube and PCF are associated with an increased likelihood of tube dependence at 6 months. Patients for preoperative tube insertion should be carefully selected and early oral feeding reintroduction should be encouraged.

Irradiation dose to the swallowing apparatus impacts nutritional status in head and neck cancer patients-results from the prospective randomized HEADNUT trial

PURPOSE

To investigate the influence of radiation dose to the swallowing muscles on the nutritional status in patients with head and neck cancer undergoing primary or adjuvant (chemo)radiotherapy (C)RT.

METHODS

Between 2018 and 2020, 61 patients were prospectively randomized into the so-called HEADNUT trial (head and neck cancer patients undergoing nutritional intervention). Follow-up was continued until 2022. Contouring of the swallowing apparatus included the superior (scm), middle (mcm), and inferior constrictor muscle (icm), the cricopharyngeal muscle (cphm), and the esophageal inlet. Nutritional status was assessed by bioelectrical impedance analysis (BIA) at the beginning and the end of radiotherapy. The posttherapeutic nutritional status was evaluated by the BIA-derived fat-free mass index (FFMI; kg/m2). Malnutrition was assumed at FFMI values of < 15 (women) and < 17 (men) kg/m2. To find differences between dosimetric parameters in well- and malnourished patients, Mann-Whitney U test was used. To model the association between malnutrition and its potentially influencing variables, several logistic regression models were built.

RESULTS

The following parameters differed between well- and malnourished patients at the end of therapy: icm Dmean, V40Gy (%), V50Gy (%), and V60Gy (%), and sphm V40Gy (%). After entering these parameters into a multivariable logistic regression model (dosimetric model), icm Dmean (b = -0.12; Exp(b) = 0.88; 95% CI: 0.78-1.0; p = 0.06) and icm V40Gy (%; b = 0.06; Exp(b) = 1.07; 95% CI: 1-1.13; p = 0.04) proved to be independent dosimetric predictors of malnutrition. We only determined the cut-off value for predicting malnutrition for icm V40Gy (%) since it was the only parameter which met p < 0.05. The optimal cut-off value for the predictor V40Gy (%) based on the Youden Index was 85.6%. Another logistic regression model (dosimetric-clinical model) consisted of icm V40 (%) and the clinical parameters tumor localization, malnutrition before RT, gender, and combined chemotherapy. It was confirmed that both icm V40% (b = -1.9; Exp(b) = -2.7; 95% CI: 0.01-0.8; p = 0.03) and malnutrition at baseline (b = -1.9; Exp(b) = 4.4; 95% CI: 8.4-816.6; p = 0.0002) were independent predictors of subsequent malnutrition the end of RT.

CONCLUSION

Establishment of a normal nutritional status before the start of RT and adherence to dose constraints for the swallowing apparatus may prevent malnutrition in head and neck cancer patients at the end of therapy. Specifically, we suggest an icm V40Gy (%) of more than 86% to be predictive for nutritional complications.

Monitoring the effect of perioperative nutritional care on body composition and functional status in patients with carcinoma of gastrointestinal and hepatobiliary system and pancreas

BACKGROUND

The significance of nutritional care in the management of cancer, particularly in the surgical treatment of abdominal cancer, is increasingly acknowledged. Body composition analysis, such as the Bioelectric impedance assay (BIA), and functional tests, e.g., handgrip strength, are used when assessing nutritional status alongside general and nutritional history, clinical examination, and laboratory tests. The primary approach in nutritional care is individually adjusted nutritional counselling and the use of medical nutrition, especially oral nutritional supplements. The aim of the study was to investigate the effects of perioperative nutritional care on body composition and functional status in patients with carcinoma of the gastrointestinal tract, hepatobiliary system, and pancreas.

PATIENTS AND METHODS

47 patients were included, 27 received preoperative and postoperative nutritional counselling and oral nutritional supplements (Group 1), while 20, due to surgical or organisational reasons, received nutritional care only postoperatively (Group 2). The effect of nutritional therapy was measured with bioimpedance body composition and handgrip measurements.

RESULTS

Group 2 had a higher average Nutritional Risk Screening (NRS) 2002 score upon enrolment (3 vs. 2 points); however, there was no difference when malnutrition was assessed using Global Leadership in Malnutrition (GLIM) criteria. There was a relative increase in lean body mass and fat-free mass index (FFMI) 7 days after surgery in group 1 (+4,2% vs. -2,1% in group 2). There was no difference in handgrip strength.

CONCLUSIONS

Our results indicate that combined preoperative and postoperative nutritional care is superior to only postoperative nutritional care. It seems to prevent statistically significant lean mass loss 7 days after surgery but not after 14 days or 4 weeks.

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.

Development of Machine-Learning Prediction Programs for Delivering Adaptive Radiation Therapy With Tumor Geometry and Body Shape Changes in Head and Neck Volumetric Modulated Arc Therapy

Purpose

During radiation therapy for head and neck cancer using volumetric modulated arc therapy, excessive dosing or underdosing occurs as a result of the decrease in tumor volume and changes in body weight. Adaptive radiation therapy (ART) is performed when significant changes are observed; however, the decision to implement ART depends on the oncologist's subjective judgment. The purpose of this study was to present objective indicators for ART and develop a program to predict the need for ART.

Methods and Materials

The study included 47 patients in the non-ART group and 21 patients in the ART group with shape changes. Patients who received ART could not be covered with the prescribed radiation therapy dose due to shape changes. For each patient, 1112 6-dimensional lists were created, including the number of irradiations, amount of change in the clinical target volume (CTV), rate of change in CTV, mean oral cavity dose, age, and body mass index. Support vector machine and k-nearest neighbor were used for machine learning. The random number of test data to be extracted varied from 1 to 9, and a mean accuracy score was calculated. These programs could predict the need for ART if the accuracy score was high.

Results

The classification accuracy of the list, including the amount of change in the CTV and rate of change in CTV up to 20 fractions, was 0.963 and 0.967 for support vector machine and k-nearest neighbor, respectively.

Conclusions

This program predicted the need for ART with more than 90% accuracy based on shape changes over time in cone beam computed tomography analysis for up to 20 fractions. This may provide significant support for objective decisions to implement ART based on the amount of change over time during treatment.

Changes in Nutritional Status of Cancer Patients Undergoing Proton Radiation Therapy Based on Real-World Data

Methods

Observational study on 47 adult hospitalized cancer patients including 27 males and 20 females who received proton beam radiotherapy during December 2021 and August 2022. Nutritional assessments, 24 h dietary survey, handgrip strength (HGS) test, anthropometrical measurements, and hematological parameters were conducted or collected at the beginning and the completion of treatment.

Results

The rate of nutritional risk and malnutrition among the total of 47 enrolled patients was 4.3% and 12.8% at the onset of proton radiation and raised up to 6.4% and 27.7% at the end of the treatment. 42.6% of patients experienced weight loss during the proton radiotherapy, and 1 of them had weight loss over 5%, and in general, the average body weight was stable over radiotherapy. The changes in patients' 24 h dietary intakes, HGS, and anthropometrical parameters, including triceps skinfold thickness (TSF), midupper arm circumference (MUAC), and midupper arm muscle circumference (MAMC), were statistically insignificant over the treatment (all p values > 0.05). The changes in patients' hematological parameters, including total protein (TP) and serum albumin (ALB), were not statistically significant over the treatment (all p values >0.05), and the level of hemoglobin (HGB) at the end of treatment was higher than that at the onset (p < 0.05).

Conclusion

The results of this study demonstrated that proton radiotherapy might have a lighter effect on the nutritional status of cancer patients.

Prehabilitation and Rehabilitation for Patients with Lung Cancer: A Review of Where we are Today

Lung cancer is the third most common type of cancer in the UK, with nearly 50 000 new cases diagnosed a year. Treatments for lung cancer have improved in recent years with the advent of new surgical and radiotherapy techniques and the increased use of immunotherapies. These advances have resulted in increasing numbers of patients surviving beyond the completion of their treatment. Lung cancer patients are now not dying from their cancer diagnosis, but from other co-existing pathologies. Lung cancer patients commonly present with multiple comorbidities. Mitigating the effects of poor lifestyles and changing behaviours may improve the efficacy of treatments, reduce side-effects and improve the quality of life for lung cancer patients. Published evidence supports the use of interventions to manage behavioural habits, to optimise the health of patients. There is no consensus as to what, when or how to embed these into the patient pathway. Supporting patients before, during and after their cancer treatments to increase activity, eat well and stop smoking have been seen to decrease side-effects and improve patient outcomes and wellbeing. The challenge is to provide a package of interventions that is acceptable to patients and fits within the patient pathway so as not to conflict with diagnostic and therapeutic activities. This article reviews where we are today with providing behavioural support to optimise the health of lung cancer patients undergoing treatment.

Assessment of nutritional status of oncology patients at hospital admission: A Portuguese real-world study

Background

Nutritional status in patients with cancer has a determining role in the evolution of the disease and tolerance to treatments. Severity of undernutrition impacts morbidity and mortality in cancer patients and can limit patient response to the optimal therapies if nutritional issues are not appropriately addressed and managed. Despite the importance of malnutrition for the clinical evolution of oncology patients, there is not yet a universally accepted standard method for evaluating malnutrition in such patients. The aim of this study was to stratify the nutritional status of inpatients at an Oncology Department.

Methods

This is an observational study with 561 cancer patients, assessed at admission to a Medical Oncology Department from November 2016 to February 2020. All patients were considered eligible. Non-compliant and/or comatose patients were excluded. Nutritional status was assessed using the PG-SGA, BMI classified with the WHO criteria, and calculation of the percentage of weight loss in the previous 3-6 months.

Results

A total of 561 patients (303 F: 258 M; mean age 65 ± 13 years) were included. One-third of the patients, n=191/561 (34%), lost 6% of their weight in the month prior to admission and 297/561 (53%) patients lost 10.2% of weight in the previous 6 months. Mean BMI was 24.1 ± 5.8 kg/m2; N = 280/561 (50%) patients had regular BMI according to the WHO criteria. N = 331/561 (59%) patients reported eating less in the month prior to admission. N = 303/561 (54%) had moderate/severe deficits of muscle and adipose compartments. The PG-SGA identified 499/561 (89%) patients as moderately/severely malnourished, of which 466/561 (83%) patients scored ≥9 points, meeting criteria for a critical need for nutritional support. Fifteen percent of patients scored >4 points, indicating a need for directed therapy for symptom control and only 1% scored <2 points (maintenance nutritional counseling).

Conclusion

In this oncological setting, a higher proportion of patients were nutritionally-at-risk or with moderate/severe malnutrition. The large majority of patients in this study presented with a critical need for nutritional intervention. These findings highlight the need for an integrated assessment of nutritional status at patient referral. This will allow early and timely nutrition care, which is recommended to prevent or reverse further deterioration of the condition and to optimize treatment administration.

Subjective Global Assessment of Nutritional Status in Head and Neck Cancer Patients Treated with Radiotherapy - A Prospective Observational Study from North East India

Head and neck cancer (HNC) patients undergoing curative radiotherapy (RT) are at risk of malnutrition due to disease process as well as effects of therapy. Identifying the nutritional status of these patients at the earliest, helps to introduce adequate and timely interventions that can improve compliance and outcomes of treatment. Various tools for nutritional assessment in cancer patients have been proposed. In this prospective observational study we used the Subjective Global Assessment (SGA) questionnaire in a cohort of HNC patients receiving definitive RT at a regional cancer center of North East India. Recording of data was done at baseline, at two weekly intervals during treatment, at end of radiotherapy (EORT) and at follow-up upto 6 months. We observed that despite proper nutrition counseling, our patients suffered from malnutrition throughout their course of RT, which was at its peak by EORT but gradually improved over six months of follow-up. Pain on eating and swallowing were the most debilitating symptoms which caused significant decline of nutrient intake, body fat and muscle mass among patients together with deteriorating SGA ratings. Our results will hopefully help us design better strategies for nutrition management while delivering curative (chemo)radiotherapy for HNC patients of this region- which has one of the highest incidences of HNC in the world.

Skeletal Muscle Mass Measurement Using Cone-Beam Computed Tomography in Patients With Head and Neck Cancer

Background and purpose

Head and neck cancer (HNC) patients usually present with malnutrition during radiotherapy, leading to loss of skeletal muscle mass (SMM) and poor clinical outcomes. CT has been used in clinical practice for measuring SMM in cancer patients. However, its clinical application for monitoring SMM is limited by the expensive price and high radiation exposure. This study aimed to investigate the feasibility of cone-beam computed tomography (CBCT) for assessing SMM and its changes in HNC patients undergoing radiotherapy.

Materials and methods

This study was divided into two parts. In part 1 (n = 32), the cross-sectional of skeletal muscle area (SMA) at the third cervical vertebra (C3) based on CBCT and computed tomography (CT) was assessed. In part 2 (n = 30), CT and CBCT were performed, and patients’ weight was measured before and at four different time points during radiotherapy. SMAs at C3 were independently identified by three senior radiation oncologists. The interobserver agreement of SMA on CBCT (SMACBCT) findings was analyzed using the intraclass correlation coefficient (ICC). One-way analysis of variance was used to evaluate the interobserver variability and statistical significance for SMA measurements. CBCT and CT measurement differences and correlations were analyzed using paired sample t-test and Pearson correlation analysis, respectively. The Krouwer variant of the Bland–Altman plot was used to analyze the agreement of SMA measurements between CBCT and CT. A simple linear regression model was used to analyze the relationship of SMA measurements between the two imaging techniques, and the equation was established. A repeated-measures ANOVA was performed to evaluate the effects and interactions between weight loss, SMA loss, and time.

Results

SMACBCT demonstrated excellent interobserver reliability; no significant difference between SMACBCT and SMA on CT (SMACT) at C3 was observed in all patients. The SMACBCT and SMACT were highly correlated (r = 0.966; 95% confidence interval = 0.955–0.975; p &lt; 0.001). Bland–Altman analysis revealed that SMACBCT was generally higher than SMACT. The predicted SMA value at C3 on CT using CBCT was similar to the actual value. Moreover, significant differences between SMA and weight loss (F =10.99, p = 0.002), groups (weight loss and SMA loss) and times (4 time points) (F = 3.93, p = 0.013), and mean percent loss over time (F = 7.618, p &lt; 0.001) were noted.

Conclusion

CBCT may be used as an alternative for CT to measure SMA in HNC patients during radiotherapy.

Network pharmacology-based study to identify the significant pathways of Lentinula edodes against cancer

Lentinula edodes (LE) is known as a good food source with potent anticancer efficacy, but its active chemical compounds and pathways against cancer have not been revealed. This study was to uncover the active chemical constituents and pathways of LE against cancer through network pharmacology. The chemical compositions were recognized by gas chromatography-mass spectrometry (GC-MS) and filtered drug-like compounds (DLCs) by SwissADME. Targets related to filtered compounds were recognized by two public databases and the final overlapping targets were identified by Venn diagram. Then, protein-protein interaction (PPI) and pathway-target-compound (PTC) networks were built by RStudio. Ultimately, we recognized the key compounds and targets via molecular docking test (MDT). A total of 33 compounds from LE were accepted by Lipinski's rule were selected as DLCs. The 33 compounds were associated with 108 targets and a key target (cyclooxygenase2 [COX2]) was identified through PPI networks. Most significantly, inactivation of pathways in cancer and activation of peroxisome proliferator activated receptor signaling pathway were significant pathways of LE. On MDT, we identified a key compound (Indole, 2-methyl-3-phenyl) on COX2 related to inactivation of athways in cancer, additionally, the number of 6 ergostane steroids was associated with the two pathways might be dual efficacy to alleviate inflammation against cancer. Overall, 13 targets, 11 compounds, and 2 key pathways of LE were identified as the significant elements to treat cancer. Hence, this study shows therapeutic evidence to verify the promising clinical effect of LE on cancer, suggesting that LE might be an important mushroom against cancer. PRACTICAL APPLICATIONS: Lentinula edodes (LE) has been used widely in cuisine as well as alternative medicines, especially, for anticancer. The LE has rich nutritional compounds including proteins, vitamins, polyphenols, and glucans, however, most of which have a critical hurdle as poor bioavailability not to be applicable for pharmaceuticals. Its main cause is very hydrophilic property. Thus, we adopted GC-MS analysis to identify lipophilic compounds to enhance cell permeability involved in bioavailability. The compounds selected from LE were confirmed by Lipinski's rule for drug-like-compounds (DLCs). Then, we retrieved targets associated with DLCs, and multiple pathways, multiple targets, and multiple compounds against cancer on network-based analysis. In summary, our study reveals the medicinal value of LE on cancer based on the multicomponents. Overall, the aim of this work is to represent the pharmacological evidence to reveal the therapeutic efficacy of AC on cancer, suggesting that DLCs from AC might be alleviators to dampen cancer.

[Nutritional Risk Screening in head-and-neck cancer patients prior to oncological therapy]

OBJECTIVE

Head-and-neck cancer patients run a high risk of peri- or post-treatment malnutrition that can severely affect the therapy outcome. However, little is known about malnutrition under the pre-treatment condition. Therefore, this study aimed to provide a systematic description of the pre-treatment nutritional status and risk of malnutrition in this population.

MATERIAL AND METHODS

Before the onset of the oncological therapy, nutritional status of 102 head-and-neck cancer patients was assessed by body mass index (BMI), their risk of malnutrition by "Nutritional Risk Screening" (NRS). Tumour stage and site, patients' age and sex as well as oropharyngeal dysphagia were analysed as possible influence factors. The latter was quantified by the Flexible Endoscopic Evaluation of Swallowing (FEES).

RESULTS

According to BMI, malnutrition (undernutrition) was found in 6% of patients, a risk of malnutrition (NRS) in 27% of patients, and oropharyngeal dysphagia in 15%. In a linear regression, only oropharyngeal dysphagia was identified as a significant influence factor for the risk of malnutrition (β = 0.380/3.776; p < .001).

CONCLUSIONS

Pre-treatment risk of malnutrition was found in a quarter of head-and-neck cancer patients. For the early identification of this risk and for the introduction of measures that would help to avoid it, a pre-treatment examination of swallowing functions and a systematic malnutrition screening by means of NRS are recommended.

Managing Cachexia in Head and Neck Cancer: a Systematic Scoping Review

INTRODUCTION

Patients with head and neck cancer (HNC) are usually confronted with functional changes due to the malignancy itself or its treatment. These factors typically affect important structures involved in speech, breathing, chewing, swallowing, and saliva production. Consequently, the intake of food will be limited, which further contributes to loss of body weight and muscle mass, anorexia, malnutrition, fatigue, and anemia. This multifactorial condition can ultimately lead to cancer cachexia syndrome. This study aims to examine the treatment of cachexia in HNC patients.

METHODS

We systematically searched OvidMedline, PubMed, Scopus, and Web of Science for articles examining the treatment of cachexia in HNC.

RESULTS

A total of nine studies were found, and these suggested interventions including nutritional, pharmacologic, therapeutic exercise, and multimodal approaches. The nutritional intervention includes essential components such as dietary counseling, oral nutritional supplements, and medical nutritional support. Individualized nutritional interventions include oral, enteral (feeding tubes i.e., percutaneous endoscopic gastrostomy [PEG], nasogastric tube [NGT]) and parenteral nutrition. The pharmacologic interventions aim at increasing the appetite and weight of cachectic patients. Therapeutic exercise and increased physical activity can help to enhance the synthesis of muscle protein, reducing inflammation and the catabolic effects of cachexia syndrome.

CONCLUSION

Owing to the multifactorial nature of this syndrome, it is expected that the management approach should be multi-interventional. Early implementation of these interventions may help to improve survival and quality of health and life of cachectic HNC patients.

Nutritional Status Impacts Quality of Life in Head and Neck Cancer Patients Undergoing (Chemo)Radiotherapy: Results from the Prospective HEADNUT Trial

Malnutrition negatively impacts quality of life (QoL) in patients with head and neck cancer (HNC). This is the first prospective study to assess the impact of malnutrition (defined by the bioelectrical impedance analysis (BIA)-derived fat-free mass index) on QoL in patients with HNC undergoing (chemo)radiotherapy. Between October 2018 and October 2020, 58 HNC patients prospectively completed the QoL-questionnaires EORTC-QLQ-C30 and EORTC-QLQ-H&N35 at the beginning (t_b) and at the end of (chemo)radiotherapy (t_e) as well as during follow-up (t_f). At these time points, nutritional risk assessment (MUST, NRS-2002, Nutriscore), BIA measurement and laboratory testing was performed by a permanent study team. Differences between malnourished (n = 14) and well-nourished patients (n = 44) were observed in UICC classification (P < 0.001) and HPV status (P = 0.03). Well-nourished patients showed higher baseline hemoglobin (P = 0.025) and albumin (P = 0.005), but lower c-reactive protein levels (P < 0.001). At t_b, mostly malnourished patients presented with worse QoL. Multivariable analysis showed that MUST, NRS-2002, HPV status, and UICC classification were related to QoL. Nutritional status has a crucial impact on QoL. The nutritional screening protocols MUST and NRS-2002 are suitable for identifying patients at risk and predicting QoL in patients with HNC undergoing (chemo)radiotherapy.

Quality of life, HPV-status and phase angle predict survival in head and neck cancer patients under (chemo)radiotherapy undergoing nutritional intervention: Results from the prospective randomized HEADNUT-trial

PURPOSE

To analyze the impact of quality of life (QoL), nutritional and clinical indicators on overall survival in patients with head and neck squamous cell cancer (HNSCC) undergoing (chemo)radiotherapy.

MATERIALS AND METHODS

At the beginning, at the end of (chemo)radiotherapy and during follow-up, QoL was prospectively assessed using the EORTC-QLQ-C30 and -QLQ-H&N35 questionnaires. Data were analyzed in 58 out of 220 screened patients, who were randomized into a control and intervention group. All patients received a nutritional assessment including bioelectrical impedance analysis (BIA), laboratory testing, and a screening for malnutrition based on the questionnaires MUST, NRS-2002 and Nutriscore at baseline and at the end of therapy. The intervention consisted of an individualized nutritional counseling every 2 weeks.

RESULTS

Except for emotional functioning, dyspnea, financial difficulties, dental problems and weight gain, all other scales from the EORTC-QLQ-C30 and -H&N35 deteriorated during (chemo)radiotherapy. At first follow-up, patients of the control group experienced more nausea and vomiting compared to those of the intervention group (p = 0.02). After performing a multivariable model, dental problems at the end of therapy (HR: 1.03; 95% CI: 1-1.06; p = 0.03), HPV negativity (HR: 18.19, 95% CI: 1.61-204.17; p = 0.02), and baseline phase angle (HR: 0.09; 95% CI: 0.01-0.82; p = 0.03) were identified as predictors for overall survival.

CONCLUSIONS

Factors influencing overall survival in patients with HNSCC undergoing (chemo)radiotherapy are complex and multifactorial. We were able to identify QoL-related (dental problems), clinical (HPV status) and nutritional (phase angle) factors as negative predictors for survival. This study was registered within the German Clinical Trials Register (DRKS00016862).

The impact of nutritional counseling on thyroid disorders in head and neck cancer patients after (chemo)radiotherapy: results from a prospective interventional trial

Objective

To analyze the impact of nutritional counseling on the development of hypothyroidism after (chemo)radiotherapy in head and neck cancer patients to propose a new normal tissue complication probability (NTCP) model.

Materials and methods

At baseline, at the end of (chemo)radiotherapy, and during follow-up, thyroid-stimulating hormone (TSH) with free thyroxin (fT3 and fT4), nutritional status, and nutrient intake were prospectively analyzed in 46 out of 220 screened patients. Patients received (chemo)radiotherapy within an intervention (individual nutritional counseling every 2 weeks during therapy) and a control group (no nutritional counseling).

Results

Overall median follow-up was 16.5 [IQR: 12; 22] months. Fourteen patients (30.4%) presented with hypothyroidism after 13.5 [8.8; 17] months. During (chemo)radiotherapy, nutritional status worsened in the entire cohort: body mass index (p < 0.001) and fat-free mass index (p < 0.001) decreased, calorie deficit (p = 0.02) increased, and the baseline protein intake dropped (p = 0.028). The baseline selenium intake (p = 0.002) increased until the end of therapy. Application of the NTCP models by Rønjom, Cella, and Boomsma et al. resulted in good performance of all three models, with an AUC ranging from 0.76 to 0.78. Our newly developed NTCP model was based on baseline TSH and baseline ferritin. Model performance was good, receiving an AUC of 0.76 (95% CI: 0.61–0.87), with a sensitivity of 57.1% and specificity of 96.9% calculated for a Youden index of 0.73 (p = 0.004; area = 0.5).

Conclusion

Baseline TSH and ferritin act as independent predictors for radiotherapy-associated hypothyroidism. The exclusion of such laboratory chemistry parameters in future NTCP models may result in poor model performance.

Associations between Nutritional and Immune Status and Clinicopathologic Factors in Patients with Pancreatic Cancer: A Comprehensive Analysis

The aim of this study was to assess and analyze the nutritional status (NS) and immune status of pancreatic cancer (PC) patients. The retrospective analysis included 80 PC patients undergoing curative pancreatic resection in the Department of Digestive Tract Surgery of the Medical University (Katowice, Poland). Patients were divided by the tumor location (proximal vs. distal), age (≤65 years vs. >65 years), Nutritional Risk Score 2002 (NRS 2002) (<3 vs. ≥3), prognostic nutritional index (PNI) (<45 vs. ≥45), and the presence of postoperative complications (no-complication vs. complication) as well as the use of neoadjuvant chemotherapy (no neoadjuvant chemotherapy vs. neoadjuvant chemotherapy) into two subgroups, which were compared. Significantly higher weight loss was related to the proximal tumor location (p = 0.0104). Significantly lower serum total protein (p = 0.0447), albumin (p = 0.0468), hemoglobin (p = 0.0265) levels, and PNI (p = 0.03) were reported in older patients. The higher nutritional risk according to NRS 2002 was significantly associated with higher age (p = 0.0187), higher weight loss (p < 0.01), lower body mass index (BMI) (p = 0.0293), lower total lymphocyte count (p = 0.0292), longer duration of hospitalization (p = 0.020), neoadjuvant chemotherapy (p < 0.01), and preoperative biliary drainage (p = 0.0492). The lower PNI was significantly associated with higher weight loss (p = 0.0407), lower serum total protein and albumin concentration, lymphocyte count (p < 0.01) and higher neutrophil/lymphocyte (NLR), monocyte/lymphocyte (MLR), platelet/lymphocyte (PLR) ratios, and duration of hospitalization (p < 0.01). In the multiple logistic regression analysis, BMI ≥ 30 kg/m2 (OR: 8.62; 95% CI: 1.24-60.04; p = 0.029521) and NRS 2002 ≥ 3 (OR: 2.87; 95% CI: 0.88-9.33; p = 0.048818) predicted postoperative complications. In the multiple linear regression analysis, the higher NRS 2002 score was linked with the longer duration of hospitalization (b = 7.67948; p = 0.043816), and longer duration of postoperative hospitalization was associated with a higher complication rate (b = 0.273183; p = 0.003100). Nutritional impairment correlates with a systemic inflammatory response in PC patients. Obesity (BMI ≥ 30 kg/m2) and malnutrition (NRS 2002 ≥ 3) predict postoperative complications, which are associate with a longer hospital stay. Assessment of nutritional and immune status using basic diagnostic tools and PNI and immune ratio (NLR, MLR, PLR) calculation should be the standard management of PC patients before surgery to improve the postoperative outcome.

Understanding Cachexia in Head and Neck Cancer

One of the major comorbidities of cancer and cancer therapy is posing a global health problem in cancer cachexia. Cancer cachexia is now considered a multifactorial syndrome that presents with drastic loss of body weight, anorexia, asthenia, and anemia. Head and neck cancer (HNC) patients are at a greater risk for development and severity of cachexia syndrome as there is direct involvement of structures associated with nutritional intake. Yet, the scientific evidence, approach, and management of cachexia in HNCs are yet to be largely explored. The article aims to succinctly review the concepts of cancer cachexia with relevance to HNCs and summarizes the current findings from recent research.

Digestion-Specific Acupuncture Effect on Feeding Intolerance in Critically Ill Post-Operative Oral and Hypopharyngeal Cancer Patients: A Single-Blind Randomized Control Trial

Malnourishment is prevalent in patients suffering from head and neck cancer. The postoperative period is crucial in terms of nutritional support, especially after composite resection and reconstruction surgery. These patients present with a number of risk factors that aggravate feeding intolerance, including postoperative status, prolonged immobility, decreased head elevation, mechanical ventilation, and applied sedative agents. Routine management protocols for feeding intolerance include prokinetic drug use and post-pyloric tube insertion, which could be both limited and accompanied by detrimental adverse events. This single-blind clinical trial aimed to investigate the effects of acupuncture in postoperative feeding intolerance in critically ill oral and hypopharyngeal cancer patients. Twenty-eight patients were randomized into two groups: Intervention group and Control group. Interventions were administered daily over three consecutive postoperative days. The primary outcome revealed that the intervention group reached 70% and 80% of target energy expenditure (EE) significantly earlier than the control group (4.00 ± 1.22 versus 6.69 ± 3.50 days, p = 0.012), accompanied by higher total calorie intake within the first postoperative week (10263.62 ± 1086.11 kcals versus 8384.69 ± 2120.05 kcals, p = 0.004). Furthermore, the intervention group also needed less of the prokinetic drug (Metoclopramide, 20.77 ± 48.73 mg versus 68.46 ± 66.56 mg, p = 0.010). In conclusion, digestion-specific acupuncture facilitated reduced postoperative feeding intolerance in oral and hypopharyngeal cancer patients.

Head and neck cancer patients under (chemo-)radiotherapy undergoing nutritional intervention: Results from the prospective randomized HEADNUT-trial

PURPOSE/OBJECTIVE

Patients with squamous cell carcinoma of the head and neck undergoing (chemo-)radiotherapy are at high risk of malnutrition. Nevertheless, there is still a lack of prospective, randomized trials investigating the influence of nutritional status on therapy-related toxicity and patients' outcome.

MATERIALS AND METHODS

Between October 2018 and October 2020, 61 patients were randomized into an intervention and control group. Questionnaires (MUST, NRS-2002, and Nutriscore), clinical examinations, laboratory analyses, and bioelectrical impedance analysis (BIA) were used to assess nutritional status for all patients at the beginning and end of therapy as well as every 2 weeks during therapy. The intervention consisted of an individualized nutritional counseling every 2 weeks during therapy.

RESULTS

Median baseline BMI for all participants was 23.8 (14.5-37.2) kg/m² and dropped to 22.9 (16.8-33) kg/m² after therapy (p < 0.001). In all patients, median baseline fat-free mass index (FFMI) was 18.1 (14-24.7) kg/m² and decreased to 17.8 (13.4-21.6) kg/m² till the end of therapy (p < 0.001). Compliant patients with a BMI < 22 kg/m² presented with less weight loss in the intervention group compared to the control (p = 0.015, CI: 0.33-2.95). At baseline, MUST was the only screening-test which showed both good sensitivity (86%) and specificity (88%) in detecting malnutrition. Median follow-up was 15 (1-26) months and is still ongoing. 2-year overall survival rate was 70% in the control and 79% in the intervention group (log-rank p = 0.79). Pretherapeutic phase angle, posttherapeutic FFMI and albumin level were prognostic indicators for overall survival (log-rank p = 0.002, p = 0.008 and p = 0.016).

CONCLUSIONS

Malnutrition negatively impacts patients' outcome under (chemo-)radiotherapy. Baseline phase angle, posttherapeutic FFMI and albumin level are proposed as reliable indicators for overall survival. This study was registered within the German Clinical Trials Register (DRKS00016862).

Status of Treatment and Prophylaxis for Radiation-Induced Oral Mucositis in Patients With Head and Neck Cancer

Radiation-induced oral mucositis (RIOM) is one of the most frequent complications in head and neck cancer (HNC) patients undergoing radiotherapy (RT). It is a type of mucosal injury associated with severe pain, dysphagia, and other symptoms, which leads to the interruption of RT and other treatments. Factors affecting RIOM include individual characteristics of HNC patients, concurrent chemoradiation therapy, and RT regimen, among others. The pathogenesis of RIOM is not yet fully understood; however, the release of inflammatory transmitters plays an important role in the occurrence and development of RIOM. The five biological stages, including initiation, primary damage response, signal amplification, ulceration, and healing, are widely used to describe the pathophysiology of RIOM. Moreover, RIOM has a dismal outcome with limited treatment options. This review will discuss the epidemiology, pathogenesis, clinical appearance, symptomatic treatments, and preventive measures related to this disease. We hope to provide a reference for the clinical treatment and prevention of RIOM in HNC patients after RT.

Nutritional Deficiencies in Radiotherapy-Treated Head and Neck Cancer Patients

Nutritional deficiencies (malnutrition, cachexia, sarcopenia, and unfavorable changes in the body composition) developing as a side effect of radiotherapy (RT) currently represents a significant but still inaccurately studied clinical problem in cancer patients. The incidence of malnutrition observed in head and neck cancer (HNC) patients in oncological radiology departments can reach 80%. The presence of malnutrition, sarcopenia, and cachexia is associated with an unfavorable prognosis of the disease, higher mortality, and deterioration of the quality of life. Therefore, it is necessary to identify patients with a high risk of both metabolic syndromes. However, the number of studies investigating potential predictive markers for the mentioned purposes is still significantly limited. This literature review summarizes the incidence of nutritional deficiencies in HNC patients prior to therapy and after the commencement of RT, and presents recent perspectives for the prediction of unfavorable nutritional changes developing as a result of applied RT.

Impact of geniohyoid and masseter muscle masses on dysphagia after salvage surgery and radiotherapy in head and neck cancer

This study aimed to determine whether geniohyoid and/or masseter muscle mass can predict the severity of dysphagia after salvage surgery for head and neck cancer. We conducted a retrospective cohort study of 45 male patients with head and neck cancer (median age, 68 years) who underwent salvage surgery. The preoperative geniohyoid and masseter muscle masses were evaluated using computed tomography and the severity of dysphagia was evaluated by Penetration Aspiration Scale (PAS), Functional Oral Intake Scale (FOIS) and Oropharyngeal swallow efficiency (OPSE). The median PAS, FOIS and OPSE scores after surgery were 7 (interquartile range [IQR] 1–8), 6 (IQR 2–7) and 95.8 (IQR 67.1–116.2), respectively. The mean geniohyoid muscle masses were 3.13 ± 0.78 cm² and the mean masseter muscle masses were 4.37 ± 0.99 cm², respectively. The multivariate analysis showed that the geniohyoid muscle mass was significantly associated with the PAS, FOIS and OPSE scores. Conversely, the masseter muscle mass was not significantly associated with the PAS score but was significantly associated with the FOIS and OPSE scores. Geniohyoid muscle mass may predict the severity of dysphagia after salvage surgery.

The Status of Nutritional Management Guidelines for Head and Neck Cancer Patients

Introduction

Head and neck cancer (HNC) is the seventh leading cause of cancer worldwide. Approximately 35%-60% patients with HNC are malnourished from the disease onset, malnutrition being associated with worsened health outcomes among these patients. This study aimed to review and synthesize existing guidelines regarding nutritional interventions in HNC patients and assess providers’ knowledge, opinions, and practice of guidelines for the nutritional management of HNC patients.

Methods

This is a multimethod study that includes a systematic review of guidelines for nutritional intervention in HNC patients and a providers’ survey regarding their knowledge and opinions regarding nutrition therapy guidelines for HNC patients.

Results

Our review yielded seven guidelines. Of the seven guidelines reviewed, all were specific to cancer patients, however, only three were specific for HNC patients. Three of the guidelines recommended using a nutritional screening tool, however, only two mentioned a specific screening tool. Out of 193 surveys included in our analysis, the highest percentage of respondents were physicians (52.4%), followed by registered nurses (33.5%). The majority of respondent (77.5%) worked in a hospital-based practice, while 18.8% worked in clinic-based practice. A large proportion (46.6%) of respondents were not aware of nutritional guidelines for HNC patients; with 23.6% not aware of any, and 23.0% aware of their existence but not aware of their content. The majority (81.5%) of respondents said that a more detailed guideline should be available for HNC patient with regards to nutrition.

Conclusion

Nutritional deficiencies in HNC patients continue to cause significant complications in treatment and recovery. Existing practice guidelines are limited and lack specific recommendations. A universal standard of care with regard to addressing nutrition in HNC patients is needed to improve healthcare outcomes among NHC patients. 

Impact of early nutrition counseling in head and neck cancer patients with normal nutritional status

BACKGROUND

Nutritional counseling is frequently overlooked in cancer patients with normal nutritional status. This study aimed to evaluate the impact of nutritional counseling in head and neck cancer (HNC) patients with normal nutritional status prior to concurrent chemoradiotherapy (CCRT).

METHODS

A total of 243 patients with pretreatment normal nutritional status and locally advanced HNC receiving concurrent chemoradiotherapy (CCRT) at three medical centers were enrolled. All patients were retrospectively allocated into the early (≤ 2 weeks, n = 105, 43.2%), late (> 2 weeks, n = 102, 42.0%), and no nutritional counseling groups (n = 36, 14.8%) according to the time interval between the date of CCRT initiation and the first date of nutritional counseling for comparison.

RESULTS

The 1-year overall survival rates were 95.0%, 87.5%, and 81.3% in the early, late, and no nutritional counseling groups (p = 0.035), respectively. The median body weight changes at end of CCRT were - 4.8% (range, - 13.3 to 8.7%), - 5.6% (range, - 21.9 to 5.6%), and - 8.6% (range, - 20.3 to 2.4%) in patients in the early, late, and no nutritional counseling groups, respectively. The early termination of chemotherapy rates and the incompletion rates of planned radiotherapy were 1.9% and 1.9%, 2.9%, and 2.0%, 13.9%, and 19.4% in patients in the early, late, and no nutritional counseling groups, respectively.

CONCLUSIONS

Our findings strongly suggest that while some HNC patients may have pretreatment normal nutritional status, early nutritional counseling is nevertheless essential for the improvement of treatment tolerance and survival outcome.

AA genotype of PLIN1 13041A>G as an unfavourable predictive factor of malnutrition associated with fat mass loss in locally advanced head and neck cancer male patients treated with radiotherapy

Introduction

Malnutrition is a frequently diagnosed condition in head and neck cancer (HNC) patients after radiation therapy (RTH). Malnutrition causes adipose tissue dysfunction associated with intensified lipolysis and disruption of the activity of mechanisms that protect adipose tissue against this process, which include the protective function of perilipin.

Material and methods

The purpose of this study was the evaluation of the predictive value of 13041A>G PLIN1 polymorphism in the development of malnutrition related to adipose tissue loss in a group of 80 patients with locally advanced HNC treated by means of radical radiation therapy.

Results

After the completion of RTH, men with AA genotype had significantly lower fat mass (FM compared to men with G haplotype; FM: 13.84 ± 6.36 kg and 19.06 ± 6.30 kg (p = 0.009). In consequence of RTH, the AA genotype carriers lost an average of 37.01% adipose tissue mass and patients with GA and GG genotypes lost 12.82 and 0.31% (p = 0.035), respectively. AA genotype was also associated with higher chance of ≥ 10%, ≥ 20% and ≥ 30% FM loss in the course of RTH (OR = 13.78; 5.78; 2.28).

Conclusions

The evaluation of such molecular factors as SNP 13041A>G may have higher predictive value in the development of malnutrition associated with severe loss of fat mass than the subjective scales, e.g., SGA and NRS-2002. The presence of AA genotype on men with HNC before RTH may facilitate earlier nutritional intervention and supportive treatment aimed at limiting or preventing body mass and fat mass loss during the applied treatment.

The Value of Laboratory Parameters for Anemia, Renal Function, Systemic Inflammation and Nutritional Status as Predictors for Outcome in Elderly Patients with Head-and-Neck Cancers

The purpose of this study was to evaluate the value of routine blood markers regarding their predictive potential for treatment outcomes of elderly head-and-neck squamous cell carcinoma (HNSCC) patients. In total, 246 elderly HNSCC patients (≥65 years) undergoing (chemo)radiotherapy from 2010 to 2018 were analyzed for treatment outcomes, depending on their hemoglobin, glomerular filtration rate (GFR), C-reactive protein (CRP) and albumin values, representing anemia, kidney function, inflammation and nutrition status, respectively. Local/locoregional control, progression-free and overall survival (OS) were calculated using the Kaplan–Meier method. Cox analyses were performed to examine the influence of blood parameters on oncological outcomes. In the univariate Cox regression analysis, hemoglobin ≤ 12 g/dL (HR = 1.536, p < 0.05), a GFR ≤ 60 mL/min/1.73 m² (HR = 1.537, p < 0.05), a CRP concentration > 5 mg/L (HR = 1.991, p < 0.001) and albumin levels ≤ 4.2 g/dL (HR = 2.916, p < 0.001) were significant risk factors for OS. In the multivariate analysis including clinical risk factors, only performance status (HR = 2.460, p < 0.05) and baseline albumin (HR = 2.305, p < 0.05) remained significant prognosticators. Additionally, baseline anemia correlated with the prevalence of higher-grade chronic toxicities. We could show for the first time that laboratory parameters for anemia (and at least partly, tumor oxygenation), decreased renal function, inflammation and reduced nutrition status are associated with impaired survival in elderly HNSCC patients undergoing (chemo)radiotherapy.

The Impact of Critical Weight Loss and Reactive Feeding Tubes on Cancer-Specific Survival in Head and Neck Cancer

Critical weight loss (CWL) continues to be a major issue in head and neck cancer (HNC) and many patients require tube feeding. We investigated the use of reactive feeding tubes (RFTs), associated CWL, and the impact on cancer-specific survival (CSS). A single-institution, retrospective audit was conducted on 460 adult HNC patients who received radiotherapy ± chemotherapy between 2005 and 2017. CSS in patients with CWL and RFTs was compared to those with no tube. Prediction analysis for RFT insertion was also performed. CWL occurred in 53% of patients, and in 88% of those with a RFT (p < 0.001). In patients with CWL, those with a RFT had worse 5 and 10-year CSS compared to those with no tube (68% and 65% vs 83% and 80% respectively, p = 0.040) in multivariate Cox regression analysis. Concurrent chemoradiotherapy combined with CWL was the strongest predictor for RFT insertion (p = 0.003). CWL, combined with having a RFT, impacts negatively on CSS. CWL may be one of the triggers for RFT insertion, however those with no tube have better CSS. This may be due to higher weight loss levels seen in those who have a RFT, and earlier insertion to prevent such losses seems indicated.

Effects of early nutritional intervention on oral mucositis in patients with radiotherapy for head and neck cancer

BACKGROUND

To observe the effect of early nutritional intervention on radiation-induced oral mucositis and nutritional status in patients with head and neck cancer (HNC).

METHODS

A total of 54 HNC patients were divided into early (28 cases) and late (26 cases) nutritional intervention groups. The early group received enteral nutrition at the beginning of radiotherapy (RT), while the late group received enteral nutrition after restricted feeding. Operators reported and assessed the timing and extent of oral mucositis and nutritional status during treatment. The nutritional status assessment indicators included body weight; body mass index (BMI); Patient-Generated-Subjective Global Assessment (PG-SGA) score; levels of albumin, hemoglobin and pre-albumin and total lymphocyte count.

RESULTS

The incidence of high-grade oral mucositis was significantly lower in the early group than that in the late group (P < 0.05). Nutritional status assessments showed more significant weight and BMI losses in the late group than in the early group at weeks 4 and 7 after RT (P < 0.01). The albumin decreased in the late group at week 7 after RT was more significant than that in the early group (P < 0.05). Albumin, hemoglobin and pre-albumin levels and total lymphocyte count decreased significantly in both groups (P > 0.05). During therapy, more patients in the early group were well-nourished and fewer were malnourished according to PG-SGA scores (P < 0.05).

CONCLUSION

Early nutritional intervention can reduce the incidence of high-grade oral mucositis during RT in patients with HNC and improve the nutritional status during treatment, which has important clinical significance.

Validation of a simple diet self-assessment tool (SDSAT) in head and neck cancer patients undergoing radiotherapy

PURPOSE

The simple diet self-assessment tool (SDSAT) is a simple instrument for estimating the cancer patients' dietary intake. This study aimed to evaluate its reliability and validity among head and neck (HNC) cancer patients undergoing radiotherapy (RT).

METHODS

Two studies were conducted at the department of radiation oncology of a University-affiliated hospital, where HNC patients were assessed at baseline, mid-treatment and post-treatment of RT. In the first study, 25 patients (a total of 60 cases) were recruited by convenience sample method to estimate the interrater reliability of SDSAT. Then, 304 patients (a total of 912 cases) were involved in a prospective, longitudinal observational study. The criterion validity was confirmed by the agreement rate between SDSAT and 24-h dietary recall (24HR). The predictive validity was established by exploring the impact of the score of SDSAT on weight loss among HNC patients during RT.

RESULTS

The estimation of interrater reliability of SDSAT showed that weighted kappa was 0.82 (95%CI = 0.74-0.90, p < 0.001), suggesting a high level of agreement between two raters. The overall agreement rate between SDSAT and 24HR was 62.9% (574/912) and weighted kappa was 0.66 (95%CI = 0.63-0.70, p < 0.001), which indicated good criterion validity. Generalized estimating equation (GEE) showed that the score of SDSAT had a significant impact on weight loss (β = 1.40, 95%CI = 1.21-1.59, p < 0.001), which demonstrated good predictive validity.

CONCLUSIONS

The SDSAT demonstrated favorable reliability and validity. It is appropriate for estimation of dietary intake among HNC patients.

Intensity-modulated radiotherapy does not decrease the risk of malnutrition in esophageal cancer patients during radiotherapy compared to three-dimensional conformal radiation therapy

Background

Esophageal cancer is a lethal disease of global scope. Radiotherapy is the main method to treat esophageal cancer; however, it concurrently leads to malnutrition. Intensity-modulated radiotherapy (IMRT) is superior to three-dimensional conformal radiation therapy (3D-CRT) in dosimetry and clinical outcomes. In this cohort study, we aimed to compare the effect of 3D-CRT and IMRT on malnutrition status.

Methods

We retrospectively included 79 esophageal cancer patients (IMRT: n=27, 3D-CRT: n=52) who received radiotherapy. We collected nutrition indexes at the beginning, the second week, and the end of radiotherapy. Paired-T test was used to evaluate the nutrition status during radiotherapy in each group. Chi-square test and independent-sample T-test were applied to compare the dynamic changes of indexes between IMRT and 3D-CRT groups.

Results

The baselines of the two groups are comparable. Nutrition Risk Screening 2002 (NRS-2002) score, body weight, BMI, hemoglobin, lymphocyte, total protein, and albumin values were significantly reduced during radiotherapy in both groups. The dynamic changes of nutrition indexes during radiotherapy were not significantly different between the IMRT and 3D-CRT groups. Besides, no difference was found for radiation esophagitis or treatment completion between the two groups.

Conclusions

Malnutrition occurs in esophageal cancer patients during radiotherapy. IMRT did not significantly decrease the risk of malnutrition compared to 3D-CRT.

Nutritional experiences in head and neck cancer patients

OBJECTIVE

Extensive research has documented the negative nutritional impact of head neck cancer (HNC) treatment, but few studies have addressed the patients' experiences. The purpose of this study was to describe how patients with HNC experience the nutritional situation and perceive nutritional support from diagnosis to the post-treatment phase.

METHODS

Patients with HNC were recruited from a randomised pilot study. Individual interviews were conducted after radiotherapy with 10 participants aged 49 - 70 years and analysed by qualitative content analysis.

RESULTS

Undergoing surgery was experienced as a poor nutritional starting point for the upcoming radiotherapy. During radiotherapy, increasing side effects made the participants customise their meals to improve food intake. About halfway through radiotherapy, virtually no food intake was experienced and hospital admissions and initiations of tube-feeding occurred in this period. Oral nutritional supplements were recommended for all, but eventually became unbearable to ingest. When radiotherapy was finally completed, the participants felt discouraged about the persistent side effects preventing them from resume eating. The participants missed tailored information about development of side effects and involvement of a dietitian when reflecting on the treatment-period.

CONCLUSION

The comprehensive nutritional problems experienced by patients with HNC require early nutritional assessments and improved individually tailored nutritional support.

The influence of nutritional status on the incidence of postoperative complications in patients following distal pancreatectomy

Introduction

Malnutrition is a common problem in hospitalised patients. The immunological, inflammatory, and nutritional status of patients significantly influences the postoperative outcome.

Aim

To assess and analyse the influence of the nutritional status on postoperative complications in patients following distal pancreatectomy.

Material and methods

The analysis included 50 patients operated in a large centre of gastrointestinal surgery. The clinicopathological parameters were analysed, and the nutritional status was assessed. The prognostic nutritional index (PNI) was calculated as 10 × serum albumin (g/dl) + 0.005 × total lymphocyte count (per mm³). The immunological parameters, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/monocyte ratio (LMR) were calculated. Patients were divided into two groups according to the presence of early postoperative complications: those without postoperative complications and those with postoperative complications.

Results

Early postoperative complications were observed in 15 (30.0%) patients undergoing distal pancreatectomy. Postoperative pancreatic fistula (POPF) was the most frequent complication noted in 11 (22%) patients. Significantly higher Nutritional Risk Screening (NRS) 2002 (p = 0.005) and lower PNI (median value: 56 vs. 41, p = 0.0003) were noted in patients with postoperative complications. In laboratory results, the significantly lower total lymphocyte count (median value: 2.4 vs. 1.4 per mm³, p = 0.01) and serum level of albumin (median value: 4.7 vs. 3.3 g/dl, p = 0.0003) were noted in the complications group.

Conclusions

Nutritional status significantly influences the incidence of postoperative complications in patients following distal pancreatectomy. Assessment of nutritional status using PNI calculation should be the standard management of patients before surgical treatment.

Nutritional parameters associated with hospital admissions in patients being treated for head and neck cancer

PURPOSE

This study analysed nutritional parameters (baseline body mass index (BMI), weight changes and enteral nutrition (EN) use, and their association with hospital admissions during radiotherapy in patients with head and neck cancer (HNC)).

METHODS

A retrospective review of patients diagnosed with HNC and treated with radiotherapy between October 2012 and April 2014 was conducted. Data on each subject's diagnosis, age, sex, chemotherapy, previous surgery, EN use, weight changes, and BMI were examined for their association with hospital admissions during treatment.

RESULTS

Eighty-three patients were included, mean age (±standard deviation) = 61 (± 11 years). Thirty-four percent had self-reported weight loss at diagnosis, and mean BMI was 26.2 ± 5.3 kg/m². Mean weight change during treatment was - 5.1 ± 6.2%. Ten patients used EN, with mean weight stabilisation during EN use (0.3 ± 5.1%). Higher presenting BMI, younger age, and definitive radiotherapy ± chemotherapy predicted greater weight loss (p < 0.05). Critical weight loss ≥ 5% was associated with a higher number of hospital admissions for nutrition reasons (n = 10) (p = 0.011) compared with those without critical weight loss (n = 2). EN use was associated with a higher number of nutrition-related admissions; however, it did not predict length of stay among those admitted.

CONCLUSION

Critical weight loss during radiotherapy was associated with unplanned nutrition-related hospital admissions. Higher BMI was associated with greater weight loss during radiotherapy, whilst EN use assisted in weight preservation. Further research around patient selection for nutritional interventions aimed at preventing critical weight loss and unplanned hospital admissions is needed.

Malnutrition in head and neck cancer patients: Impacts and indications of a prophylactic percutaneous endoscopic gastrostomy

INTRODUCTION

Head and neck cancer (HNC) patients often experience malnutrition before and during treatment. Prophylactic gastrostomy has emerged as an efficient tool for ensuring adequate nutrition. However, there is no suitable algorithm able to identify patients at high risk of malnutrition. The aim of this study was to describe the nutritional management, to assess the impact of prophylactic gastrostomy, and to identify predictors of malnutrition.

METHODS

This retrospective study included 152 patients treated with surgery, radiotherapy, or chemotherapy for HNC. The patients were classified according to their gastrostomy status (prophylactic or non-prophylactic). Nutritional, tumoral and treatment characteristics were reported. Clinical and nutritional outcomes were measured 6 weeks after the beginning of treatment. In order to describe the nutritional management and the impact of prophylactic gastrostomy on patients, univariate analysis was generated using chi-square test and Mann-Whitney test or Student's t-test. Logistic regression was performed to identify factors associated with malnutrition.

RESULTS

Forty-one patients received prophylactic gastrostomy whereas 111 patients had no nutritional support. Prophylactic gastrostomy placement was associated with a lower initial body mass index, with severe malnutrition, and with initial oral intake disorder. Patients who did not experienced prophylactic gastrostomy had much worse outcomes such as hospital readmissions (P=0.042), relative weight loss at 6 weeks (P<0.0001), dysphagia, severe malnutrition, and poor state of health (P=0.001). Our complication rates (4.9%) were lower than the usual range (5.9-9.3%) and no life-threatening complication was reported. Positive N status, oral intake disorder, concomitant radiochemotherapy, nasopharyngeal, and hypopharyngeal tumor site were significant predictive factors for malnutrition.

CONCLUSIONS

Prophylactic percutaneous endoscopic gastrostomy showed advantages in terms of hospital readmissions, relative weight loss at 6 weeks, dysphagia, severe malnutrition, and poor state of health. Tumoral, nutritional and treatment characteristics seem to be predictors for malnutrition. Hence, physicians should integrate these factors in their nutrition algorithm approach.

Relationship Between -2028 C/T SELP Gene Polymorphism, Concentration of Plasma P-Selectin and Risk of Malnutrition in Head and Neck Cancer Patients

Until today there is a lack of molecular factors, that could predict either cancer malnutrition or cachexia. Among potential mechanisms, that contribute to development of above syndromes, the systemic inflammatory response with overproduction of cytokines and adhesion molecules is the most likely. Recent papers suggested crucial role of P-selectin adhesion molecule in the initiation of leukocytes recruitment to the site of injury during inflammation, promotion of tumor aggressiveness and contribution to cancer cachexia. The aim of the study was to investigate SELP -2028 C/T polymorphism as a risk factor of malnutrition in 66 head and neck cancer (HNC) patients subjected to radiotherapy. Genotyping was conducted by real-time PCR method by means of TaqMan SNP Genotyping Assay. P-selectin Human ELISA Kit was used to determine P-selectin concentration in each extracted plasma samples. CC homozygous subjects had 4-fold higher risk score of being qualified as severely malnourished compared to other genotype carriers (p = 0.015). However, the TT homozygous patients were at lowest risk of severe weight loss >10% during the therapy period (OR = 0.20; p = 0.019). We also noted, that CC genotype carriers had significantly higher risk of early death incidence compared to CT or TT genotype (median survival time: 29 vs 34 months; HR = 3.02; p = 0.0085). Studied SELP -2028 C/T seems to be a novel attractive predictive factor of cancer malnutrition in HNC patients, perhaps in a future, patients carrying unfavorable CC genotype could be earlier scheduled for pharmaceutical intervention with parenterall nutrition, therefore they could be prevented from the development of severe malnutrition or even cachexia.
