Nutritional screening and early treatment of malnutrition in cancer patients

Advancing body composition assessment in patients with cancer: First comparisons of traditional versus multicompartment models

BACKGROUND AND AIMS

Measurement of body composition using computed tomography (CT) scans may be a viable clinical tool for low muscle mass assessment in oncology. However, longitudinal assessments are often infeasible with CT. Clinically accessible body composition technologies can be used to track changes in fat-free mass (FFM) or muscle, though their accuracy may be impacted by cancer-related physiological changes. The purpose of this study was to examine the agreement among accessible body composition method with criterion methods for measures of whole-body FFM measurements and, when possible, muscle mass for the classification of low muscle in patients with cancer.

METHODS

Patients with colorectal cancer were recruited to complete measures of whole-body DXA, air displacement plethysmography (ADP), and bioelectrical impedance analysis (BIA). These measures were used alone, or in combination to construct the criterion multicompartment (4C) mode for estimating FFM. Patients also underwent abdominal CT scans as part of routine clinical assessment. Agreement of each method with 4C model was analyzed using mean constant error (CE = criterion - alternative), linear regression including root mean square error (RMSE), Bland-Altman limits of agreement (LoA) and mean percentage difference (MPD). Additionally, appendicular lean soft tissue index (ALSTI) measured by DXA and predicted by CT were compared for the absolute agreement, while the ALSTI values and skeletal muscle index by CT were assessed for agreement on the classification of low muscle mass.

RESULTS

Forty-five patients received all measures for the 4C model and 25 had measures within proximity of clinical CT measures. Compared to 4C, DXA outperformed ADP and BIA by showing the strongest overall agreement (CE = 1.96 kg, RMSE = 2.45 kg, MPD = 98.15 ± 2.38%), supporting its use for body composition assessment in patients with cancer. However, CT cutoffs for skeletal muscle index or CT-estimated ALSTI were lower than DXA ALSTI (average 1.0 ± 1.2 kg/m2) with 24.0% to 32.0% of patients having a different low muscle classification by CT when compared to DXA.

CONCLUSIONS

Despite discrepancies between clinical body composition assessment and the criterion multicompartment model, DXA demonstrates the strongest agreement with 4C. Disagreement between DXA and CT for low muscle mass classification prompts further evaluation of the measures and cutoffs used with each technique. Multicompartment models may enhance our understanding of body composition variations at the individual patient level and improve the applicability of clinically accessible technologies for classification and monitoring change over time.

Comparison between AWGC-cachexia and GLIM-malnutrition in patients with gastric cancer

BACKGROUND

The newly released Asian Working Group for Cachexia (AWGC) criteria share similar diagnostic items with the Global Leadership Initiative on Malnutrition (GLIM) criteria. This study aims to compare the AWGC cachexia and GLIM malnutrition in patients with gastric cancer and investigate whether one diagnosis continues to be a prognostic factor in individuals diagnosed with the other condition.

METHODS

Data of patients who underwent radical gastrectomy for gastric adenocarcinoma were prospectively collected from 2013 to 2019. The AWGC and GLIM criteria were applied to diagnosis cachexia and malnutrition, respectively. Univariate and multivariate logistic and Cox regression were used to verify the effect of relevant factors on postoperative complications and overall survival.

RESULTS

A total of 1420 patients were included, among whom 174 (12.3 %) were diagnosed with AWGC-cachexia alone, 85 (6.0 %) were diagnosed with GLIM-malnutrition alone, and 324 (22.8 %) had both AWGC-cachexia and GLIM-malnutrition. Both AWGC-cachexia and GLIM-malnutrition were independent risk factors for complications and overall survival. When they coexisted, the odds ratios (OR) and hazard ratios (HR) tended to be higher. In the AWGC-cachexia subset, GLIM-malnutrition remained an independent risk factor (HR = 1.544, 95 % CI = 1.098-2.171, P = 0.012) for overall survival after the adjustment of confounding factors. Similarly, in the GLIM-malnutrition subset, AWGC-cachexia remained an independent risk factor for overall survival (HR = 1.697, 95 % CI = 1.087-2.650, P = 0.020). Patients with both cachexia and malnutrition had the worst overall survival.

CONCLUSION

AWGC-cachexia and GLIM-malnutrition criteria were two non-redundancy tools in reflecting mortality risk in preoperative nutritional assessment.

Effect of a multimodal intervention in breast Cancer patients undergoing neoadjuvant therapy: A study protocol of the multimodal project

BACKGROUND AND AIMS

To determine the effect of a multimodal intervention (nutritional behavior change and physical exercise) on quality of life, chemotherapy response rate and tolerance, histopathological level of the tumor, body composition, and biochemical parameters, in patients diagnosed with breast cancer during neoadjuvant chemotherapy treatment, and to compare them with the control group.

METHODS

Anticipated 80 patients diagnosed with breast cancer aged 18-70 years will be recruited for this randomized, unblinded clinical trial based on a nutritional behavior change and physical exercise in patients during the approximately 6 months in which the patient receives neoadjuvant treatment. Participants will be randomly allocated (1:1) to one of two groups (intervention or control). Primary and secondary outcomes will be assessed before the beginning and after the neoadjuvant treatment (before surgery). The primary outcome is quality of life, whereas secondary outcomes include chemotherapy response rate and tolerance, histopathological level of the tumor and body composition (i.e., visceral adipose tissue activity, bone, lean and fat masses). We will analyze blood parameters (i.e., biochemical, inflammatory, and tumor markers) as exploratory outcomes.

CONCLUSION

This study will address the influence of a practical and viable multimodal intervention (i.e., nutritional behavior change and physical exercise) on breast cancer patients undergoing neoadjuvant chemotherapy. Given the practical viability of the intervention in real-world settings, our study holds promise for significant scientific and clinical implications.

The association between malnutrition risk and revised Edmonton Symptom Assessment System (ESAS-r) scores in an adult outpatient oncology population: a cross-sectional study

BACKGROUND

Cancer-associated malnutrition is associated with worse symptom severity, functional status, quality of life, and overall survival. Malnutrition in cancer patients is often under-recognized and undertreated, emphasizing the need for standardized pathways for nutritional management in this population. The objectives of this study were to (1) investigate the relationship between malnutrition risk and self-reported symptom severity scores in an adult oncology outpatient population and (2) to identify whether a secondary screening tool for malnutrition risk (abPG-SGA) should be recommended for patients with a specific ESAS-r cut-off score or group of ESAS-r cut-off scores.

METHODS

A single-institution retrospective cross-sectional study was conducted. Malnutrition risk was measured using the Abridged Patient-Generated Subjective Global Assessment (abPG-SGA). Cancer symptom severity was measured using the Revised Edmonton Symptom Assessment System (ESAS-r). In accordance with standard institutional practice, patients completed both tools at first consult at the cancer centre. Adult patients who completed the ESAS-r and abPG-SGA on the same day between February 2017 and January 2020 were included. Spearman's correlation, Mann Whitney U tests, receiver operating characteristic curves, and binary logistic regression models were used for statistical analyses.

RESULTS

2071 oncology outpatients met inclusion criteria (mean age 65.7), of which 33.6% were identified to be at risk for malnutrition. For all ESAS-r parameters (pain, tiredness, drowsiness, nausea, lack of appetite, shortness of breath, depression, anxiety, and wellbeing), patients at risk for malnutrition had significantly higher scores (P < 0.001). All ESAS-r parameters were positively correlated with abPG-SGA score (P < 0.01). The ESAS-r parameters that best predicted malnutrition risk status were total ESAS-r score, lack of appetite, tiredness, and wellbeing (area under the curve = 0.824, 0.812, 0.764, 0.761 respectively). Lack of appetite score ≥ 1 demonstrated a sensitivity of 77.4% and specificity of 77.0%. Combining lack of appetite score ≥ 1 with total ESAS score > 14 yielded a sensitivity of 87.9% and specificity of 62.8%.

CONCLUSION

Malnutrition risk as measured by the abPG-SGA and symptom severity scores as measured by the ESAS-r are positively and significantly correlated. Given the widespread use of the ESAS-r in cancer care, utilizing specific ESAS-r cut-offs to trigger malnutrition screening could be a viable way to identify cancer patients at risk for malnutrition.

Nutritional Prognosis of Patients Submitted to Radiotherapy and Its Implications in Treatment

Oncological patients show intense catabolic activity, as well as a susceptibility to higher nutritional risk and clinical complications. Thus, tools are used for monitoring prognosis. Our objective was to analyze the nutrition prognosis of patients who underwent radiotherapy, correlating it with outcomes and complications. We performed a retrospective transversal study based on secondary data from hospital records of patients who started radiotherapy between July 2022 and July 2023. We established Prognostic Scores through a combination of Prognostic Nutritional Index (PNI) and a Subjective Global Assessment (SGA), assessed at the beginning and end of treatment. Score 3 patients, with PNI ≤ 45.56 and an SGA outcome of malnutrition, initially presented a higher occurrence of odynophagia, later also being indicative of reduced diet volume, treatment interruption, and dysphagia. SGA alone showed sensitivity to altered diet volume, dysphagia, and xerostomia in the second assessment. Besides this, PNI ≤ 45.56 also indicated the use of alternative feeding routes, treatment interruption, and hospital discharge with more complications. We conclude that the scores could be used to indicate complications; however, further studies on combined biomarkers are necessary.

Challenges in identifying malnutrition in obesity; An overview of the state of the art and directions for future research

(Protein-energy) malnutrition in individuals living with obesity presents complex diagnostic challenges due to the distinctive physiological characteristics of obesity. This narrative review critically examines the identification of malnutrition within the population with obesity, distinguishing malnutrition in obesity from related conditions such as sarcopenic obesity. While noting some shared features, the review highlights key differences between these conditions. The review also highlights the limitations of current malnutrition screening tools, which are not designed for individuals living with obesity. These tools primarily rely on anthropometric measurements, neglecting (among others) nutrient intake assessment, which hinders accurate malnutrition detection. Additionally, this review discusses limitations in existing diagnostic criteria, including the Global Leadership Initiative on Malnutrition (GLIM) criteria, when applied to individuals living with obesity. Challenges include the identification of appropriate cut-off values for phenotypic criteria (unintentional weight loss, low body mass index and muscle mass) and aetiological criteria such as reduced food intake and inflammation for the population with obesity. Overall, this review emphasises the need for modified screening tools and diagnostic criteria to recognise and assess malnutrition in obesity, leading to improved clinical outcomes and overall wellbeing.

Pretherapeutic factors predicting conversion surgery in unresectable pancreatic ductal adenocarcinoma: A retrospective study

Recently, conversion surgery (CS) has been reported to improve the prognosis in patients with unresectable pancreatic ductal adenocarcinoma (UR-PDAC) with a favorable response to intense chemotherapy or chemoradiotherapy. However, few pretherapeutic parameters predict the attainability of CS in patients with UR-PDAC. The present study aimed to explore the pretherapeutic predictors for the attainability of CS in patients with UR-PDAC. The present study retrospectively evaluated 130 patients with UR-PDAC treated at Gifu University Hospital (Gifu, Japan) from January 2015 to December 2021. Survival analysis was performed using the Simon and Makuch-modified Kaplan-Meier method. The hazard ratio (HR) was estimated using a time-varying Cox regression model. The association between each predictor and CS was evaluated using the univariate analysis and age-adjusted Fine-Gray sub-distribution hazard model. The bootstrap bias-corrected area under the receiver operating characteristic curve analysis for predicting CS was used to assess the cut-off values for each predictor. The cumulative incidence rate was calculated with CS as the outcome when divided into two groups based on the cut-off value of each pretherapeutic predictor. Among the 130 patients included in the analysis, only 14 (11%) underwent CS. The median survival time was significantly longer in patients who underwent CS compared with patients without CS (56.3 vs. 14.1 months; P<0.001). The age-adjusted Fine-Gray sub-distribution hazard regression showed that the total protein (TP) [HR 2.81, 95% confidence interval (CI) 1.19-6.65; P=0.018], neutrophil-to-lymphocyte ratio (NLR) (HR 0.53, 95% CI 0.31-0.90; P=0.020), and lymphocyte-to-monocyte ratio (LMR) (HR 1.28, 95% CI 1.07-1.53; P=0.006) were significantly associated with CS. Moreover, TP ≥6.8, NLR <2.84 and LMR ≥3.87 were associated with a higher cumulative incidence of CS. In conclusion, pretherapeutic TP, NLR and LMR are clinically feasible biomarkers for predicting the attainability of CS in patients with UR-PDAC.

Survival Predictors Before Preoperative Adjuvant Chemotherapy in Patients With Locally Advanced Esophageal Squamous Cell Carcinoma

BACKGROUND/AIM

Radical resection after preoperative adjuvant chemotherapy (NAC) is a standard treatment for patients with locally advanced esophageal squamous cell carcinoma (LAESCC), but its outcome remains unsatisfactory. In order to develop a personalized treatment program for LAES, we herein compared the survival prediction utility of five pre-NAC nutritional, inflammatory, and immune indexes in patients with LAESCC.

PATIENTS AND METHODS

We evaluated the survival of 203 patients with LAESCC who underwent radical resection after NAC from January 2011 to September 2019 for the following representative pre-NAC nutritional, inflammatory, and immune indices: modified Glasgow Prognostic Score, Prognostic Nutritional Index, C-reactive protein/albumin ratio, serum neutrophil/lymphocyte ratio, and Geriatric Nutrition Risk Index (GNRI) were evaluated for their impact on survival.

RESULTS

Of the five indices, GNRI was the best predictor of survival as determined by the area under the curve (p<0.05). When patients were divided into three groups according to the nutritional risk assessment of Bouillanne et al. using the pre-NAC GNRI, the 5-year overall survival (OS) and recurrence-free survival (RFS) were significantly stratified (p<0.001). On multivariate analysis, the GNRI independently identified a poor OS group [group 1: hazard ratio (HR)=2.598, p=0.002; group 2: HR=6.257, p<0.001] and a high recurrence risk group (group 1: HR=1.967, p=0.016; group 2: HR=4.467, p<0.001).

CONCLUSION

In patients with LAESCC, GNRI may be the most accurate, reliable, and useful prognostic factor among the five major systemic inflammatory and nutritional indices.

Assessment of malnutrition in patients undergoing chemotherapy at the National Oncology Centre of the Korle-Bu Teaching Hospital, Accra, Ghana

Background

Globally, cancer is on the rise despite several interventions. The link between nutrition and cancer has long been established with the consequences of poor nutrition on cancer pathway being dire. Early nutrition intervention is recommended for all cancer patients.

Objective

To assess malnutrition among patients undergoing chemotherapy at the National Radiotherapy Oncology and Nuclear Medicine Centre of the Korle-Bu Teaching hospital (KBTH) in Accra, Ghana.

Methods

A cross-sectional study was conducted among 123 patients with different types and stages of cancer who were undergoing chemotherapy. Data was collected from December 2018 to January 2019. The PG-SGA tool was used to assess weight loss at one and six months, food intake and nutrition impact symptoms. A correlation test was used to test the association between PGSGA score and Nutritional triaging. A T-test was used to determine the association between chemotherapy cycles and nutrition. A p-value <0.05 was considered to be significant.

Results

The results revealed that 5.7% (n= 7) of the patients were well nourished, 31.7% (n= 39) were suspected of being malnourished and 62.6% (n=77) were severely malnourished. About half of the participants (48%) had experienced weight loss ranging between 1-20kg with weight loss ≤5kg being most prevalent at both one month and six months prior to the study. More than half (56.9%, n=70) of the participants were consuming less than their usual intake. Majority of the participants had 4-6 nutritional symptoms (39.0%) with symptoms being mostly mild (39.1%). Poor nutritional status was positively correlated with nutritional symptoms (r=0.747, p<0.001).

Conclusion

The PGSGA tool identified that more than half of the patients were severely malnourished hence the need for early nutrition intervention in cancer patients.

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.

May Nutritional Status Positively Affect Disease Progression and Prognosis in Patients with Esophageal and Pharyngeal Cancers? A Scoping Review of the Current Clinical Studies

BACKGROUND

Malnutrition in esophageal and pharyngeal cancer patients constitutes a common and serious concern, which significantly reduces patients' prognoses. Cancers of the esophagus and the pharynx can considerably impair feeding in patients, resulting in severe undernutrition. This is a scoping review that intends to critically analyze the most well-designed clinical studies investigating the potential beneficial impact of diverse nutritional assessment tools on the prognosis of patients with esophageal and pharyngeal cancers.

METHODS

The most accurate and remarkable scientific databases were comprehensively explored utilizing relative keywords to detect clinical studies that investigate whether nutritional status may affect disease prognosis.

RESULTS

Several assessment tools have evaluated and highlighted the potential beneficial impact of nutritional status on disease progression and patients' prognosis in both esophageal and pharyngeal cancers. Regarding esophageal cancer, CONUT, PNI, PG-SGA, and NRS-2002 are more commonly used, while albumin is also frequently evaluated. Regarding pharyngeal cancers, fewer studies are currently available. PNI has been evaluated, and its significance as a factor for shorter survival' times has been highlighted. The Comprehensive Nutritional Index has also been evaluated with positive results, as well as NRS 2002, GPS, and body-weight status. However, there is currently a lack of studies with an adequate number of women with cancer. An international literature gap was identified concerning follow-up studies with adequate methodology.

CONCLUSIONS

Nutritional status may significantly affect disease progression and patients' survival, highlighting the significance of a great nutritional status in individuals with esophageal and pharyngeal cancers. Further large-scale and well-designed prospective surveys should be performed to verify the potential beneficial effects of adequate nourishment in people suffering from cancer of the esophagus and pharynx.

Role of preoperative malnutrition and symptom severity in anorexia-cachexia-related quality of life in patients with operable pancreatic cancer

PURPOSE

This study assessed the changes in malnutrition status, symptom severity, and anorexia-cachexia-related quality of life (QoL) before and after pancreatic surgery and identified significant factors associated with changes in anorexia-cachexia-related QoL in patients with operable pancreatic cancer.

METHODS

In total, 76 patients with pancreatic cancer who were scheduled to undergo surgery were recruited from a medical center in northern Taiwan. The Mini Nutritional Assessment, Symptom Severity Scale, and Functional Assessment of Anorexia-Cachexia Therapy scale were used to assess the patients' nutritional status, symptom severity, and anorexia-cachexia-related QoL, respectively. Bioelectrical impedance analysis was performed using X-Scan Plus II to assess body composition. A generalized estimating equation approach was used to identify significant factors associated with anorexia-cachexia-related QoL.

RESULTS

In total, 42.1% of the patients had malnutrition or were at risk of malnutrition before surgery. Preoperative malnutrition (β = -3.857, p = .001) and higher early satiety (β = -0.629, p = .005), insomnia (β = -0.452, p = .025), and pain (β = -0.779, p < .001) were associated with lower anorexia-cachexia-related QoL.

CONCLUSION

Clinicians should actively assess the nutritional status of patients with pancreatic cancer before surgery and provide symptom cluster management interventions to improve nutrition, insomnia, and pain, which is crucial for enhancing patients' anorexia-cachexia-related QoL.

Bioimpedentiometry parameters used as indicators of frailty and malnutrition: association between G8 score and Phase angle (PHA) in elderly cancer patients

BACKGROUND

Since the incidence of cancer increases with age, in older cancer patients important information may be missed without a Comprehensive Geriatric Assessment (CGA). On the other side, CGA is a time-consuming and complex instrument, so that Geriatric 8 (G8) has been proposed as a more feasible screening tool to identify patients who could benefit from a CGA evaluation. G8 consists of 8 questions (patient age + 7 items derived from the Mini Nutritional Assessment questionnaire). A G8 score ≤ 14 is considered associated with frailty and risk of malnutrition. Another screening test is Bioelectrical Impedance Analysis (Bioimpedentiometry, BIA), which enables to evaluate the nutritional status through a specific parameter known as Phase angle (PhA). This study is aimed at assessing the ability of G8 alone or in combination with PhA to detect elderly cancer patients at higher risk for malnutrition who cannot undergo immediate anticancer treatments.

METHODS

A total of 289 cancer patients (168 men and 121 women) aged ≥ 70 years old were enrolled and performed both G8 test, body mass index (BMI) and BIA assessments. A concurrent G8 score ≤ 14 and PhA < 5 defined subjects most exposed to the risk of malnutrition.

RESULTS

An association between BMI and G8 (p < 0.001, OR 1.54) and a clinically significant relationship between G8 and PhA (p = 0.013) were observed.

CONCLUSION

G8 can be used to identify patients at risk for malnutrition who would benefit from comprehensive CGA. The concurrent use of G8 and BIA presents a higher power in discriminating subjects at higher risk of malnutrition than a single test. This study suggests the need for routine assessment of nutritional status in cancer patients using combinations of methods, in order to implement strategies for individually-tailored care before starting any treatment.

Closing the cancer care gap with a patient-reported nutrition screening: A retrospective analysis of a quality improvement project on an oncology ward (CCC study)

BACKGROUND & AIMS

Early identification of patients at risk for malnutrition followed by individualized nutrition interventions is a central step to the provision of appropriate nutrition care. However, a health care professional (HCP)-based nutrition screening is not always consistently integrated into routine care. Patient-reported (PR) nutrition screening could thus potentially alleviate the burden on the HCPs and contribute to a greater number of patients who are identified and treated for malnutrition.

METHODS

In 2021 a Quality Improvement Project (QIP) at our out-patient oncology clinic was undertaken to implement the change from a HCP-based nutrition screening to a PR-screening. This was followed by a retrospective analysis in which the primary outcome measure was the rate of nutrition consultations initiated for patients undergoing cancer therapy.

RESULTS

In total n = 1657 patient data sets derived from comparable time periods before and after the QIP were analyzed and compared. Both groups had a comparable mean age and gender distribution. The most common diagnosis in both groups was gastrointestinal tumors. The change in routine care from a HCP-based nutrition screening to a PR-screening led to a significant increase in nutrition consultation rates (RD = 19%; p < 0.001; 95% CI 14.4%-23.5%) and screening rates (RD = 30.5%; p < 0.001; 95% CI 26.2%-34.7%).

CONCLUSIONS

The change to PR-screening potentially facilitates an increase in nutrition screening rates. This in turn leads to an increased rate of patients identified at risk for malnutrition and thus referrals for nutrition consultations. Our findings indicate that a PR nutrition screening tool could play a role in closing the care gap and contribute to reducing rates of malnutrition among this population where screening is not consistently integrated into routine care.

Compliance of postoperative gastric cancer patients with oral nutritional supplementation and its influencing factors

OBJECTIVES

To evaluate the compliance of postoperative gastric cancer patients with oral nutritional calcium supplementation and explore its influencing factors, in order to provide a reference for formulating relevant nursing interventions.

METHODS

A total of 269 postoperative patients with gastric cancer admitted to the third department of surgery of the Fourth Hospital of Hebei Medical University from February to July 2020 were selected retrospectively through convenient sampling. A general information questionnaire and the Chinese version of the modified medication adherence eight-item scale were used to conduct a cross-sectional survey, in order to evaluate the compliance of postoperative gastric cancer patients with oral nutritional supplementation.

RESULTS

A total of 269 questionnaires were distributed in this study, and 228 valid questionnaires were finally recovered. The compliance score for oral nutritional calcium supplements in postoperative patients with gastric cancer was (6.43±0.21). The results of multiple linear regression analysis showed that the patients' education level, family monthly average income, postoperative time, medication belief and social support were factors influencing postoperative compliance with oral nutritional supplementation (P<0.05).

CONCLUSIONS

The compliance of postoperative gastric cancer patients with oral nutritional calcium supplements is at a medium to low level. Patients' education level, family monthly average income, postoperative time, medication belief, and social support are the main influencing factors. It is necessary to formulate and implement relevant interventions to improve compliance.

Comparative Effects of Different Nutritional Supplements on Inflammation, Nutritional Status, and Clinical Outcomes in Colorectal Cancer Patients: A Systematic Review and Network Meta-Analysis

Nutritional supplements have been widely used in colorectal cancer (CRC) patients. The aim of this network meta-analysis (NMA) was to compare the effects of different nutritional supplements on inflammation, nutritional status, and clinical outcomes in CRC patients. Four electronic databases were searched until December 2022. Randomized controlled trials (RCTs) comparing nutritional supplements of omega-3 fatty acids (omega-3), arginine, vitamin D, glutamine, probiotics, or their combinations with placebo or standard treatment were selected. The outcomes were inflammatory indicators, nutritional indicators, and clinical outcomes. A random-effects Bayesian NMA was performed to rank the effect of each supplement. In total, 34 studies involving 2841 participants were included. Glutamine was superior in decreasing tumor necrosis factor-α (MD -25.2; 95% CrI [-32.62, -17.95]), whereas combined omega-3 and arginine supplementation was more effective in decreasing interleukin-6 (MD -61.41; 95% CrI [-97.85, -24.85]). No nutritional supplements significantly maintained nutritional indicators in CRC patients. Regarding clinical outcomes, glutamine ranked highest in reducing the length of hospital stay (MD -3.71; 95% CrI [-5.89, -1.72]) and the incidence of wound infections (RR 0.12; 95% CrI [0, 0.85]), and probiotics were rated as best in reducing the incidence of pneumonia (RR 0.38; 95% CrI [0.15, 0.81]). Future well-designed RCTs are needed to further confirm these findings.

Wearable and Invisible Sensor Design for Eye-Motion Monitoring Based on Ferrofluid and Electromagnetic Sensing Technologies

For many human body diseases, treatments in the early stages are more efficient and safer than those in the later stages; therefore, detecting the early symptoms of a disease is crucial. One of the most significant early indicators for diseases is bio-mechanical motion. This paper provides a unique way of monitoring bio-mechanical eye motion based on electromagnetic sensing technology and a ferro-magnetic material, ferrofluid. The proposed monitoring method has the advantages of being inexpensive, non-invasive, sensor-invisible and extremely effective. Most of the medical devices are cumbersome and bulky, which makes them hard to apply for daily monitoring. However, the proposed eye-motion monitoring method is designed based on ferrofluid eye make-up and invisible sensors embedded inside the frame of glasses such that the system is wearable for daily monitoring. In addition, it has no influence on the appearance of the patient, which is beneficial for the mental health of some patients who do not want to attract public attention during treatment. The sensor responses are modelled using finite element simulation models, and wearable sensor systems are created. The designed frame of the glasses is manufactured based on 3-D printing technology. Experiments are conducted to monitor eye bio-mechanical motions, such as the frequency of eye blinking. Both the quick blinking behaviour with an overall frequency of around 1.1 Hz and the slow blinking behaviour with an overall frequency of around 0.4 Hz can be observed through experimentation. Simulations and measurements results show that the proposed sensor design can be employed for bio-mechanical eye-motion monitoring. In addition, the proposed system has the advantages of invisible sensor set-up and will not affect the appearance of the patient, which is not only convenient for the daily life of the patient but also beneficial for mental health.

The prognostic value of comprehensive geriatric assessment on the management of older patients with small cell lung cancer

BACKGROUND/AIMS

The prognostic value of a comprehensive geriatric assessment (CGA) for the management of older small cell lung cancer (SCLC) patients remains to be established.

METHODS

A retrospective cohort enrolled 21 SCLC patients over 65 years from March 2018 to 2019 at the Yonsei Cancer Center. The CGA included the following instruments: frailty, body mass index, sarcopenia (circumference of arm and calf, Timed Up and Go test, grip strength), comorbidity, polypharmacy, activities of daily living (ADL), Instrumental ADL, nutrition, depression, and cognitive function. The correlations of oncological and geriatric variables with overall survival (OS) were determined. The log-rank test with Cox model and Kaplan-Meier method were used for the analysis.

RESULTS

The median age was 75 years (range, 67 to 85). All patients had the Eastern Cooperative Oncology Group performance status 0-2. The median survival was 9.93 months (range, 1.53 to 36.30). Among CGA parameters, ADL and nutritional status had significant differences in OS in univariate analysis. In multivariate analysis, only nutritional status was independently associated with survival (hazard ratio, 0.17; 95% confidence interval, 0.05 to 0.57). Median OS for low nutritional status was 5.63 months and the normal nutrition group was 15.5 months (p = 0.004).

CONCLUSION

Pre-treatment nutritional status measured by CGA appears to be a predictor of OS in older SCLC patients. However, for further generalization of the implication of CGA in SCLC, a larger scale study with prospective design is strongly needed.

The Prognostic Impact of Pretreatment Geriatric Nutritional Risk Index in Patients with Diffuse Large B-Cell Lymphoma

The prognostic value of the geriatric nutritional risk index (GNRI) is not clear in patients with diffuse large B-cell lymphoma (DLBCL). This study was designed to analyze the GNRI in DLBCL patients and to investigate its prognostic value in DLBCL. The archive records of DLBCL patients between 2008 and 2020 at the Akdeniz University Hospital were retrospectively analyzed. A total of 206 patients with DLBCL were recruited and classified into two GNRI-based groups based on nutrition status. The GNRI cut off value was determined by ROC analysis. In the univariate Cox regression analysis for overall survival (OS), age, lactate dehydrogenase, B symptoms, infiltration of bone marrow, and the GNRI were determined as prognostic factors for mortality. The OS of patients with a GNRI ≤104.238 was significantly lower than that of patients with a GNRI >104.238 (p = 0.001). The progression-free survival (PFS) of patients with GNRI ≤104.238 was significantly lower compared to the patients with GNRI >104.238 (p = 0.010). Based on the results of the present study with a relatively large hospital-based cohort, the GNRI can be recommended for use as an independent prognostic marker for OS and PFS in patients with DLBCL.

Role of Nutrition in Pediatric Patients with Cancer

Children with cancer are at high risk for developing short-term and long-term nutritional problems related to their underlying disease and side effects of multimodal treatments. Nutritional status (NS) can influence several clinical outcomes, such as overall survival (OS) and event-free survival (EFS), treatment tolerance, risk of developing infections and quality of life (QoL). However, the importance of nutrition in children with cancer is still underestimated. This review focuses on alterations of NS that occurs in children during cancer treatment. In particular, we reviewed the pathogenesis of undernutrition in oncological children, as well as how NS affects treatment tolerance and response, the immune system and the risk of infections of children with cancer. Thanks to recent advances in all types of supportive therapy and to the progress of knowledge on this topic, it has been realized that NS is a modifiable prognostic factor that can be intervened upon to improve the outcome of these patients. Currently, there is a lack of a systematic approach and standard recommendations for nutritional care in the pediatric cancer population. Literature analysis showed that it is essential to define the NS and treat any alterations in a timely manner ensuring proper growth and development. Nutritional follow-up should become an integral part of the care pathway. Regular nutritional monitoring should be performed at diagnosis, during treatment and during follow-up. A close collaboration and sharing of expertise between pediatric oncologists and nutrition specialists, combined with careful and participatory sharing of the feeding experience with the family and the child (after age 6 years), is strongly required.

Impact of serum albumin concentration and neutrophil-lymphocyte ratio score on gastric cancer prognosis

INTRODUCTION/AIM

Serum albumin concentration (COA) and neutrophil-lymphocyte ratio (NLR) could reflect immunological and nutritional status. We aim to evaluate the impact of COA-NLR score on the prognosis of gastric cancer (GC).

MATERIAL AND METHODS

We perform a retrospective analysis on a database of 637 GC cases, between January 2010 and December 2017. In 396 patients, the inclusion criteria for this study were met (non-resectional or palliative surgery were excluded). Analytic data was only available in 203 patients. COA-NLR score was defined as follows: COA under 35 g/L and NLR value of 2.585 or higher, score 2; one of these conditions, score 1; and neither, score 0.

RESULTS

In our population (n = 203), 87 patients were classified as score 0, 82 as score 1 and 34 as score 2. COA-NLR score was significantly associated with DFS (HR 1.674; CI 95% 1.115-2.513; p = 0.013) and with OS (HR 2.072; CI 95% 1.531-2.805; p < 0.001). Kaplan-Meier curve analysis (log rank test) revealed that a higher score of COA-NLR predicted a worse OS (p < 0.001) and DFS (p = 0.03). COA-NLR was an independent prognostic factor for OS when adjusted to pStage and age (adjusted HR 1.566; CI 95% 1.145-2.143; p = 0.005).

CONCLUSIONS

Preoperative COA-NLR score was significantly associated with worse OS and DFS and, in this way, with worse prognosis on GC patients submitted to curative-intent resectional surgery.

Nutritional Assessment in Cancer Patients

Malnutrition in cancer patients is highly prevalent. The metabolic and physiologic changes associated with the disease and the side effects of treatment regimens all combine together to produce a detrimental effect on the patient's nutritional status. A poor nutritional status significantly reduces the efficacy of treatment methods and the patient's overall chances of survival. Therefore, an individualized nutrition care plan is essential to counter malnutrition in cancer. Nutritional assessment is the first step of this process which sets the foundation for developing an effective intervention plan. Currently, there is no single standard method for nutritional assessment in cancer. Hence, to get a true picture of the patient's nutritional state, a comprehensive analysis of all aspects of the patient's nutritional status is the only reliable strategy. The assessment includes anthropometric measurements and evaluation of body protein status, body fat, inflammation markers, and immune markers. A thorough clinical examination which factors in the medical history and physical signs, along with the dietary intake patterns of the patient, is also important components of nutritional assessment of cancer patients. To facilitate with the process, various nutritional screening tools like patient-generated subjective global assessment (PGSGA), nutrition risk screening (NRS), and malnutrition screening tool (MST) have been developed. While these tools have their own benefits, they only give a glimpse of the nutritional problems and do not bypass the need for a complete assessment employing various methods. This chapter covers all four of the elements of nutritional assessment for cancer patients in detail.

Clinical nutrition in surgical oncology: Young AIOM-AIRO-SICO multidisciplinary national survey on behalf of NutriOnc research group

Malnutrition is a common condition in cancer patients which is usually associated with functional limitations, as well as increased morbidity and mortality. Based on the support of the young sections of Italian Association of Medical Oncology (AIOM), Italian Association of Radiotherapy and Clinical Oncology (AIRO) and Italian Society of Surgical Oncology (SICO) merged into the NutriOnc Research Group, we performed a multidisciplinary national survey with the aim to define the awareness of nutritional issues among healthcare professionals delivering anticancer care. The questionnaire was organized in four sections, as follows: Knowledge and practices regarding Nutritional Management of cancer patients; Timing of screening and assessment of Nutritional Status; Nutritional Treatment and prescription criteria; Immunonutrition and educational topics. The modules focused on esophagogastric, hepato-bilio-pancreatic and colorectal malignancies. Overall, 215 physicians completed the survey. As regards the management of Nutritional Status of cancer patients, many responders adopted the ERAS program (49.3%), while a consistent number of professionals did not follow a specific validated nutritional care protocol (41.8%), mainly due to lack of educational courses (14.5%) and financial support (15.3%). Nearly all the included institutions had a multidisciplinary team (92%) to finalize the treatment decision-making. Cancer patients routinely underwent nutritional screening according to 57.2% of interviewed physicians. The timing of nutritional assessment was at diagnosis (37.8%), before surgery (25.9%), after surgery (16.7%), before radiochemotherapy (13.5%) and after radiochemotherapy (7%). Most of the responders reported that nutritional status was assessed throughout the duration of cancer treatments (55.6%). An important gap between current delivery and need of nutritional assessment persists. The development of specific and defined care protocols and the adherence to these tools may be the key to improving nutritional support management in clinical practice.

Esophageal stenosis as an independent factor of poor prognosis in patients with ESCC treated with definitive chemoradiotherapy

Aim: To evaluate the clinical outcome and elucidate the prognostic factors in patients with esophageal squamous cell carcinoma (ESCC) treated with definitive chemoradiotherapy (CRT). Patients: Data for patients newly diagnosed with ESCC receiving definitive CRT at our institution between 2012 and 2018 were retrospectively reviewed. Results: A total of 201 patients were included. Severe stenosis after radiotherapy was an independent factor relevant to prognosis. Maximal esophageal wall thickness, short-term responses, severe stenosis at diagnosis and a high neutrophil-to-lymphocyte ratio were independent risk factors for the occurrence of severe stenosis after radiotherapy. Conclusion: Severe stenosis after radiotherapy is a useful predictive indicator in patients with ESCC receiving definitive CRT. Further studies are needed to verify these findings.

Rehabilitation Nutrition in Patients with Chronic Kidney Disease and Cachexia

Rehabilitation nutrition is a proposed intervention strategy to improve nutritional status and physical function. However, rehabilitation nutrition in patients with cachexia and protein-energy wasting (PEW), which are the main nutrition-related problems in patients with chronic kidney disease (CKD), has not been fully clarified. Therefore, this review aimed to summarize the current evidence and interventions related to rehabilitation nutrition for cachexia and PEW in patients with CKD. CKD is a serious condition worldwide, with a significant impact on patient prognosis. In addition, CKD is easily complicated by nutrition-related problems such as cachexia and PEW owing to disease background- and treatment-related factors, which can further worsen the prognosis. Although nutritional management and exercise therapy are reportedly effective for cachexia and PEW, the effectiveness of combined nutrition and exercise interventions is less clear. In the future, rehabilitation nutrition addressing the nutritional problems associated with CKD will become more widespread as more scientific evidence accumulates. In clinical practice, early intervention in patients with CKD involving both nutrition and exercise after appropriate assessment may be necessary to improve patient outcomes.

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.

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.

Perioperative oral nutritional support for patients diagnosed with primary colon adenocarcinoma undergoing radical surgical procedures -Peri-Nutri Trial: study protocol for a randomized controlled trial

Background

Colon cancer is one of the most common cancers in Finland and worldwide. Cancer-related malnutrition is a well-known risk factor for increased morbidity and mortality after surgery, and it is associated with complications and longer hospitalizations. There are no established recommendations on how to improve the nutritional status of colon cancer patients´ during the perioperative phase. Administration of simple oral nutritional supplements has been suggested to reduce complication rates, but evidence to support this practice is scarce.

Methods

The Peri-Nutri trial is a prospective, multicenter, randomized, controlled trial. Its primary endpoint is to evaluate whether perioperative oral nutritional support (ONS) decreases the number of complications during the 30-day follow-up after surgery. Secondary endpoints are to study the effect of ONS on quality of life after surgery, length of stay in institutional care, 90-day mortality rate, five-year disease-free survival and overall survival. The patients with a Nutritional risk screening 2002 (NRS-2002) questionnaire result between 2 and 5 (≥ 3 are classified at risk of malnutrition) will be randomized (1:1 ratio) into either the intervention or control group. The intervention group will receive preoperative ONS two weeks before the operation, and nutritional support will continue 10 days after the operation. The control group will not receive ONS. A total of 318 patients will be randomized into two groups and patients are followed five years.

Discussion

Peri-Nutri study evaluate the impact of ONS to short-term and long-term postoperative morbidity and mortality rates of colon cancer patients undergoing curative surgery. If ONS will decrease patients´ morbidity and mortality, that has a huge impact on patients´ quality of life and also to financial cost.

Prognostic Value of the Pre-Treatment Prognostic Nutritional Index for Patients with Unresectable Locally-Advanced and Advanced Stage Upper Gastrointestinal Tract Cancer

Purpose

The prognostic nutritional index (PNI) is used to distinguish immune-nutritional status. Previous studies have shown that it is significantly associated with patient outcomes for various malignancies. This study aimed to evaluate the prognostic impact of PNI in patients with unresectable locally-advanced and advanced stage upper gastrointestinal tract cancer, including esophageal cancer and gastric cancer.

Methods

A retrospective study of 170 unresectable stage III–IV esophageal cancer and gastric cancer patients was conducted from January 2018 to December 2020. In our retrospective analysis, the pretreatment PNI of patients was calculated and analyzed. The Youden index was estimated to select the optimal cut-off value for PNI. Univariate and multivariate flexible parametric proportional hazards models with restricted cubic splines (RCS) were used to identify independent prognostic factors, and the Kaplan–Meier method was used to estimate survival curves.

Results

The median follow-up period was 5 months (ranging from 0.06 to 36.92 months). We determined 52.9 as the cut-off value by using the maximum Youden index. Subsequently, patients in the testing group were classified into high PNI and low PNI groups. Kaplan–Meier curves showed the low PNI group had significantly poorer overall survival (OS) than the high PNI group. Median OS in the low PNI group was 4.43 months compared with 8.23 months in the high PNI group (HR 2.42, 95% CI 1.33–4.40, p = 0.004). In the univariate analysis, low PNI, ECOG PS 2, and ECOG PS 3–4 were associated with OS. According to multivariate analysis, low PNI was an independent prognostic factor for OS (HR 2.31, 95% CI 1.24–4.29, p = 0.008).

Conclusion

Pretreatment PNI is useful for independent prognosis of unresectable stage III–IV esophageal cancer and gastric cancer in patients.

Objective and Subjective Appetite Assessment in Patients with Gynecological Cancer: A Pre- and Post-Operative Pilot Study

Although appetite and its disorders have been implicated in disease progression and outcomes, ghrelin concentrations, an objective appetite measure, are rarely assessed in patients with gynecological malignancies. The present study aimed to assess changes in post-operative versus pre-operative appetite levels in patients with gynecological cancers scheduled for tumor removal surgery (N = 53). Acylated ghrelin concentrations were assessed as an objective appetite proxy, whereas the Council of Nutrition appetite questionnaire (CNAQ) was employed as a subjective appetite measure. Ghrelin concentrations were increased post-operatively (median: 12.1 pg/mL, IQR: 0.67 to 23.5, p-value = 0.001) but the perceived appetite of patients (CNAQ) remained unchanged (median: -1, IQR: -3 to 1). Tumor removal surgery decreased all anthropometric indices (body weight, body mass index, waist and hips circumferences, triceps skinfolds, body fat, fat mass and fat mass index, p-value ≤ 0.001 for all) and doubled the risk of malnutrition among patients. No difference was recorded in the change in participants' objective and subjective appetite when they were classified according to the tumor type. No correlation was observed between ghrelin concentrations and CNAQ score pre-operatively (Spearman's rho correlation coefficient = -0.181, p-value = 0.298) or post-operatively (Spearman's rho correlation coefficient = 0.071, p-value = 0.684). The observed post-operative rise in ghrelin concentrations is associated with body weight loss and consists of a possible defense mechanism of the human body, aiming to prolong survival.

Advanced lung cancer inflammation index (ALI) predicts prognosis of patients with gastric cancer after surgical resection

Introduction

Advanced lung cancer inflammation index (ALI) has been implicated in the prognosis of many types of tumors. But few studies elucidate its role in gastric cancer (GC).

Materials and methods

We consecutively recruited 615 GC patients who underwent radical gastrectomy. Patients were grouped according to ALI status. Risk factors for overall survival (OS) and disease-free survival (DFS) in overall and sex-stratified cohorts were determined using multivariate cox regression analysis. We also compared survival differences between the two groups after one-to-one propensity score matching (PSM).

Results

Patients with low ALI showed larger tumor size, more advanced TNM staging, shorter OS (median: 37 vs 42 months) and DFS (median: 37 vs 42 months) (all P < 0.001). Multivariate analysis showed that elevated ALI was independently associated with longer OS and DFS. After stratification by sex, low ALI was an independent risk factor for OS and DFS in male patients but not in female patients. But our further PSM analysis showed prognostic value of ALI in both male and female subgroups.

Conclusion

Preoperative ALI is an independent prognostic factor for GC patients undergoing curative gastrectomy.

Potential association with malnutrition and allocation of combination medical therapies in hospitalized heart failure patients with reduced ejection fraction

Malnutrition is common in patients with heart failure with reduced ejection fraction (HFrEF) and may influence the long-term prognosis and allocation of combination medical therapy. We reviewed 1231 consecutive patient-level records from a multicenter Japanese registry of hospitalized HFrEF patients. Nutritional status was assessed using geriatric nutritional risk index (GNRI). Combination medical therapy were categorized based on the use of beta-blockers, renin-angiotensin system inhibitors, and mineralocorticoid receptor antagonists. The composite outcome of all-cause death and HF rehospitalization was assessed. The mean age was 72.0 ± 14.2 years and 42.6% patients were malnourished (GNRI < 92). At discharge, 43.6% and 33.4% of patients were receiving two and three agents, respectively. Malnourished patients had lower rates of combination medical therapy use. The standardized GNRI score was independently associated with the occurrence of adverse events (hazard ratio [HR]: 0.88, 95% confidence interval [CI] 0.79-0.98). Regardless of the GNRI score, referenced to patients receiving single agent, risk of adverse events were lower with those receiving three (HR: 0.70, 95% CI 0.55-0.91) or two agents (HR: 0.70, 95% CI 0.56-0.89). Malnutrition assessed by GNRI score predicts long-term adverse outcomes among hospitalized HFrEF patients. However, its prognosis may be modified with combination medical therapy.

Chronic Inflammation in Obesity and Cancer Cachexia

Chronic inflammation has long been linked to obesity and related conditions such as type 2 diabetes and metabolic syndrome. According to current research, the increased risk of cancer in people with certain metabolic diseases may be due to chronic inflammation. Adipocytokines, which are pro-inflammatory cytokines secreted in excess, are elevated in many chronic metabolic diseases. Cytokines and inflammatory mediators, which are not directly linked to DNA, are important in tumorigenesis. Cachexia, a type of metabolic syndrome linked to the disease, is associated with a dysregulation of metabolic pathways. Obesity and cachexia have distinct metabolic characteristics, such as insulin resistance, increased lipolysis, elevated free fatty acids (FFA), and ceramide levels, which are discussed in this section. The goal of this research project is to create a framework for bringing together our knowledge of inflammation-mediated insulin resistance.

Nutrition and functional status among Palestinian cancer patients receiving chemotherapy

Objectives

This study aims to determine the prevalence of malnutrition among cancer patients and to assess the nutritional and functional status of cancer patients undergoing chemotherapy at the Oncology unit of Beit Jala Governmental Hospital in Palestine.

Methods

During the data collection period, all patients who received chemotherapy at the hospital's chemotherapy unit were included in this cross-sectional analysis. Anthropometric measurements and biochemical data from the patients' files were used to determine nutritional status. The Nutrition Risk Screening (NRS) 2002 was used to assess the risk of malnutrition. The Functional Assessment of Anorexia/Cachexia Therapy (FAACT) was used to determine functional status. A three-day diet recall was used to determine dietary intake.

Results

A total of 153 patients were included in the final analysis. The results revealed that 23.8% of the patients were at risk of malnutrition. Those who were not at risk of malnutrition had a marginally improved functional position. Furthermore, patients aged ≥65 years, males, smokers or former smokers, and those with four or more comorbidities had a significantly higher prevalence of malnutrition. In the logistic model, age >60 years was the only indicator of malnutrition.

Conclusion

Malnutrition has a considerable prevalence in the study sample. However, the functional status of patients who were not at risk of malnutrition was marginally better than that of those with malnutrition risk.

Role of Perirectal Fat in the Carcinogenesis and Development of Early-Onset Rectal Cancer

Purpose

The incidence of early-onset rectal cancer (EORC) has been increasing since the past decade, while its underlying cause remained unknown. This study was aimed at clarifying the relationship between perirectal fat area (PFA) and EORC. Patients and Methods. All patients with rectal cancer who received radical excision between January 2016 and December 2017 at our hospital were included. The fat series images of pelvic magnetic resonance imaging scans were obtained and PFA at the ischial spine level was calculated using the ImageJ software.

Results

A total of 303 patients were finally included and divided into two groups according to the median PFA: Group 1 (<20.2 cm², n = 151) and Group 2 (≥20.2 cm², n = 152). PFA positively correlated with body weight and body mass index. PFA increased with invasion depth, lymph node metastasis, TNM stage, tumor deposits, and vascular invasion. Patients with EORC had higher PFA than those with late-onset rectal cancer (LORC; P = 0.009). Among patients with stage I–III rectal cancers, those in Group 2 had significantly shorter disease-free survival (P = 0.010) and overall survival (P = 0.034) than those in Group 1, and PFA was an independent predictor of disease-free survival (OR: 1.683 [1.126-3.015], P = 0.035) and overall survival (OR: 1.678 [1.022-2.639], P = 0.046).

Conclusions

Patients with EORC had significantly higher PFA than those with LORC. PFA is positively correlated with T stage, N stage, TNM stage, tumor deposit, and vascular invasion and is an independent predictor of disease-free survival and overall survival. Therefore, perirectal fat may be involved in the carcinogenesis and development of EORC.

Sarcopenia as a novel prognostic factor in the patients of primary localized gastrointestinal stromal tumor

Background

Sarcopenia predicts poor prognosis of a variety of gastrointestinal malignancies. However, there is a lack of study on the association between skeletal muscle index (SMI) and the prognosis of gastrointestinal stromal tumor (GIST). The aim of this study is to develop a novel nomogram based on sarcopenia for GIST patients to predict overall survival (OS).

Methods

SMI was measured by computed tomography scan of 107 patients who underwent resection for primary localized gastrointestinal stromal tumor (GIST). Sarcopenia was defined by cutoff values for SMI as 40.1 cm²/m² and 39.8 cm²/m² using optimum stratification for males and females respectively. Factors were included in the nomogram were specified by univariate and multiple Cox proportional hazard analysis. Concordance index (C-index) and calibration curves were conducted to measure the discrimination and accuracy of the nomogram. The utility of the nomogram was assessed by the decision curve analysis (DCA).

Results

Twenty-eight (26.2%) of 107 patients were sarcopenic. Sarcopenia was correlated significantly with body mass index, albumin, female sex, resection style, mitotic index, rupture status, survival. Sarcopenia was significantly related to decreased overall survival (p = 0.003).The nomogram including sarcopenia status, resection style and mitotic index had an excellent discrimination with C-index 0.794. The calibration curves represented a good accordance between the actual observation and nomogram prediction for overall survival. Decision curve analysis illustrated that the nomogram was helpful in clinic.

Conclusions

We developed a nomogram based on sarcopenia to predict overall survival after resection of GISTs which is an effective and favorable prognostication tool.

Correlation of Patient Generated-subjective Global Assessment with Serum C-reactive Protein Level in Stage I–IV Head-and-neck Cancer

AIM: This study aims to identify the correlation between patient generated-subjective global assessment (PG-SGA) with serum C-reactive protein (CRP) to be used to predict inflammation and prevent cachexia in head-and-neck cancer patients. METHODS: This was a cross-sectional study using 51 patients with inclusion criteria of patients diagnosed with head-and-neck cancer irrespective of stage, age ≥18 years old, had not received treatments of radiotherapy, chemotherapy, and surgery. The statistical analysis performed was Kolmogorov–Smirnov normality test, bivariate analysis by Spearman test, and linear regression analysis. RESULTS: As many as 64.7% of the patients had PG-SGA score ≥9 (average PG-SGA score 11.7 ± 6.2). The CRP median value was 6.4 (0.4–170.4) mg/L. There was a statistically significant positive but weak correlation between PG-SGA score with serum CRP (r = 0.372 and p = 0.007) and a significant linear relationship (r2 = 0.201). CONCLUSIONS: Malnutrition risk assessment using PG-SGA showed a high prevalence of malnutrition risk in head-and-neck cancer patients. PG-SGA score is correlated with serum CRP level. Further studies are needed to confirm the result of this study.

Metabolomics and its Applications in Cancer Cachexia

Cancer cachexia (CC) is a complicated metabolic derangement and muscle wasting syndrome, affecting 50-80% cancer patients. So far, molecular mechanisms underlying CC remain elusive. Metabolomics techniques have been used to study metabolic shifts including changes of metabolite concentrations and disturbed metabolic pathways in the progression of CC, and expand further fundamental understanding of muscle loss. In this article, we aim to review the research progress and applications of metabolomics on CC in the past decade, and provide a theoretical basis for the study of prediction, early diagnosis, and therapy of CC.

High miR-511-3p Expression as a Potential Predictor of a Poor Nutritional Status in Head and Neck Cancer Patients Subjected to Intensity-Modulated Radiation Therapy

Nutritional deficiencies, including malnutrition and its irreversible type cachexia, are often observed in patients with head and neck cancer (HNC). Among the various factors contributing to the occurrence of these disorders, inflammation seems to be crucial. The potential regulatory properties of miR-511-3p, e.g., post-translational alteration of expression of genes with protein products that are involved in inflammation, may be related to nutritional deficiencies observed in HNC patients. Therefore, the aim of our study was to assess the correlation between pretreatment miR-511-3p expression and nutritional status in patients undergoing radiotherapy (RT) due to HNC. In our retrospective study, 60 consecutively admitted patients treated with intensity-modulated radiotherapy (IMRT) due to advanced HNC were enrolled. The analysis of miR-511-3p expression was performed using real-time PCR. Significantly higher expression of miR-511-3p was observed in well-nourished patients compared to patients with moderate or severe malnutrition (p = 0.0001). Pretreatment expression of miR-511-3p may be a useful biomarker of nutritional deficiencies in patients subjected to IMRT due to HNC.

The prognostic values of prognostic nutritional index in extensive-stage small-cell lung cancer

We aimed to assess the prognostic and predictive significance of pretreatment Prognostic Nutritional Index (PNI) in extensive-stage small-cell lung cancer (ES-SCLC) patients treated with first-line chemotherapy. We designed this study to evaluate the prognostic role of PNI in 147 ES-SCLC patients treated with platinum-based combination regimen between 2011 and 2018. Kaplan-Meier survival analyses and Cox proportional hazard models were used to examine the effects of basal PNI on overall survival (OS). The median age of the patients was 61 (range 38-81). The cutoff value for PNI was determined for whole group and patients were dichotomized into high (≥49.17) and low (<49.17). Seventy-eight (53.1%) patients had low PNI score and 69 (46.9%) patients had high PNI score. Patients with the high PNI score had better OS than those with low PNI (13 versus 12 months, respectively, and P = 0.03). The relationship between PNI score and OS was more prominent in patients over 65 years of age (13 versus 10 months, respectively, and P = 0.03). Progression-free survival of patients with complete response to first-line treatment was statistically significantly better than the other patients (8 versus 7 months, respectively, and P = 0.02). Similarly, OS was statistically significantly better than the other patients (15 versus 8 months, respectively, and P = 0.001). The results of our study show that PNI score is useful in evaluating the OS of patients with ES-SCLC. PNI is a cost-effective prognostic marker and should therefore be included in routine clinical practice.

The clinical impact of malnutrition on the postoperative outcomes of patients undergoing gastrectomy for gastric cancer: Propensity score matched analysis of 2011-2017 hospital database

BACKGROUND & AIMS

Malnutrition is a prominent feature of gastric cancer patients who suffer from gastric outlet obstruction, impaired peristalsis, and cancer-mediated disruptions in metabolic hemostasis. In this study, we systematically evaluate the impact of malnutrition on the postoperative outcome of patients with gastric cancer undergoing gastrectomy.

METHODS

2011-2017 National Inpatient Sample was used to isolate patients with gastric cancer who underwent gastrectomy, who were stratified using malnutrition. The malnutrition-present cohort was matched to the malnutrition-absent controls using 1:1 propensity score-matching analysis, and compared to the following endpoints: mortality, length of stay (LOS), hospitalization costs, and postoperative complications.

RESULTS

5309 were identified to have undergone gastric resection procedure for gastric cancer, from which there were 1044 with malnutrition and 1044 matched controls. Malnourished patients had higher mortality (6.80 vs 3.83% p = 0.003, OR 1.83 95% CI 1.23-2.73), LOS (17.2 vs 11.4 d p < 0.001), costs ($197,702 vs $124,133 p < 0.001), and were more often discharged to rehabilitation facilities. Malnourished patients had higher rates of wound complications (3.64 vs 1.25% p < 0.001, OR 3.00 95% CI 1.59-5.66), infection (6.90 vs 3.26% p < 0.001, OR 2.20 95% CI 1.45-3.34), and respiratory failure (6.80 vs 3.64% p = 0.002, OR 1.93 95% CI 1.29-2.89). In multivariate analysis, malnourished patients had higher rates of mortality (p = 0.002, aOR 1.87 95% CI 1.25-2.80), length of stay (p < 0.001, aOR 1.52 95% CI 1.48-1.55), costs (p < 0.001, aOR 1.61 95% CI 1.61-1.61) despite controlling for non-matched hospital variables.

CONCLUSION

In this propensity score matched analysis, malnutrition is associated with increased postoperative mortality, LOS, and hospitalization costs in patients with gastric cancer undergoing gastric resection surgery.

Age-Related Disease Risks in Younger versus Older B-Cell Non-Hodgkin's Lymphoma Survivors

BACKGROUND

Younger cancer survivors may develop age-related diseases due to the cancer treatment that they undergo. The aim of this population-based study is to estimate incidence of age-related diseases besides cardiovascular disease among younger versus older B-cell non-Hodgkin's lymphoma (B-NHL) survivors compared with their respective general population cohorts.

METHODS

Survivors of B-NHL were diagnosed between 1997 and 2015 from the Utah Cancer Registry. Using the Utah Population Database, up to 5 cancer-free individuals from the general population were matched with a B-NHL survivor on sex, birth year, and state of birth. Hazard ratios (HR) for age-related disease outcomes, which were identified from medical records and statewide health care facility data, were estimated using Cox Proportional Hazards models for B-NHL survivors diagnosed at <65 years versus ≥65 years at least 5 years since B-NHL diagnosis.

RESULTS

Comparing 2,129 B-NHL survivors with 8,969 individuals from the general population, younger B-NHL survivors had higher relative risks of acute renal failure [HR, 2.24; 99% confidence interval (CI), 1.48-3.39; P heterogeneity = 0.017), pneumonia (HR, 2.42; 99% CI, 1.68-3.49; P heterogeneity = 0.055), and nutritional deficiencies (HR, 2.08; 99% CI, 1.48-2.92; P heterogeneity = 0.051) ≥5 years after cancer diagnosis.

CONCLUSION

Younger B-NHL survivors had higher relative risks of acute renal failure, pneumonia, and nutritional deficiencies than older B-NHL survivors compared with their respective general population cohorts, ≥5 years after cancer diagnosis.

Adherence to Oral Nutritional Supplements in Patients With Gastrointestinal Cancer: A Mixed-Method Study

BACKGROUND

Oral nutritional supplements (ONS) is a cost-effective nutritional therapy in patients with gastrointestinal cancer. However, information is lacking about adherence to ONS in general clinical settings. Figuring out adherence to ONS and related factors will provide evidence for the improvement of ONS usage practice.

OBJECTIVE

The aim of this study was to survey adherence to ONS in gastrointestinal cancer patients with an ONS prescription and the factors associated with it.

METHODS

A mixed-method prospective study was conducted. Multivariate analysis and semistructured interviews were performed to identify factors that affected patient adherence to ONS.

RESULTS

Of 111 gastrointestinal cancer patients provided with an ONS prescription, the median of adherence to ONS was 50.00% (interquartile range, 28.57%-91.67%). Multivariate analysis indicated that participants with low weight showed higher adherence to ONS than those with normal weight (β = -2.61, P = .011) or overweight (β = -3.25, P = .002). Semistructured interviews on 14 participants suggested that factors related to adherence to ONS were needs perception and benefits, clarity of the target daily ONS intake, tolerance to ONS, the impact of disease or treatment, personal preference, and professional support.

CONCLUSION

This study reveals poor adherence to ONS in patients with gastrointestinal cancer and factors related to it in current clinical settings.

IMPLICATIONS FOR PRACTICE

Our findings could provide evidence for the development of strategies to improve ONS usage practice. It suggests that the practice in ONS should be improved from aspects of nutritional assessment, education, tolerance, and symptom management, as well as follow-up and monitoring of patients.

Physical and Mental Health Factors Associated with Poor Nutrition in Elderly Cancer Survivors: Insights from a Nationwide Survey

Elderly cancer survivors (patients with any stage of cancer or a history of cancer) are precious members of our society and they can be easily found in various types of surveys. As is well known, good nutrition is important in elderly people suffering from cancer. Proper nutritional evaluation and intervention not only improves their quality of life but also helps them to receive adequate treatment, thereby prolonging individual survival and reducing social healthcare costs. In this study, we retrieved elderly cancer survivors from national survey data and assessed their nutritional status as good or bad. Then, we described the individual, physical, and mental health factors between people with good and bad nutrition. Physical and psychological variables associated with poor nutritional status were evaluated through regression analysis. We investigated data from the 2017 National Survey of Older Persons, and cancer patients aged 65 years or over were eligible. A total of 360 adults were enrolled and more than half (57.2%, n = 206) were in a poor nutritional status. We applied individual variable-adjusted statistical models and discovered that limited instrumental activities of daily living (IADL) (OR 2.15, 95% CI 1.08–4.28) and poor subjective health status (OR 1.74, 95% CI 1.00–3.02) were significantly associated with poor nutrition on logistic regression. Our research findings suggested that IADL and self-rated health status needed to be addressed in old cancer survivors at nutritional risk. The early recognition and management of nutrition in these populations might help them to live longer and have a better quality of life, eventually reducing socioeconomic burdens.

Dynapenia in digestive cancer outpatients: association with markers of functional and nutritional status (the FIGHTDIGO study)

BACKGROUND

The FIGHTDIGO study determined the feasibility and acceptability of handgrip strength (HGS) measurement in digestive cancer outpatients.

PURPOSE

To assess the relationship between muscle strength and markers of functional and nutritional status in this population.

DESIGN

In this prospective study, a total of 201 patients were followed during 6 months and were asked to perform HGS measurement at each hospitalization. Anthropometric measurements, laboratory tests, and performance status (PS) evaluation were collected. The modified Glasgow Prognostic Score (mGPS) was calculated using CRP and albumin levels. Severe malnutrition was defined as body mass index (BMI) < 18 kg/m² in patients > 70 years old, and BMI < 16 kg/m² in those < 70 years old. Dynapenia was defined as HGS < 30 kg (men) and < 20 kg (women). Mixed logistic regressions and mixed linear regressions were performed to study factors associated with dynapenia and HGS value, respectively.

RESULTS

A total of 879 HGS measurements were analyzed. Dynapenia occurred in 177 measurements (20.1%). BMI and HGS were significantly associated in univariate analysis (p = 0.001). In multivariate analysis, mGPS score (β =  - 0.54 ± 0.31; p = 0.06) and severe malnutrition (β =  - 2.8 ± 1.4; p = 0.08) tended to be associated with HGS. Dynapenia was only associated with functional status impairment in univariate analysis (n = 140/803, 17.4% in ECOG 0 and 1 versus n = 37/76, 58.7% in ECOG 2 and 3; p = 0.002).

CONCLUSIONS

Identification of dynapenia using HGS measurement may be useful to predict nutritional vulnerability in digestive cancer outpatients undergoing chemotherapy. Patients could then benefit from nutritional support, adapted physical activity programs, and early therapeutic adjustments. Trial registration ClinicalTrials.gov, NCT02797197.

Nutritional Intervention Improves Nutrition Outcomes in Stomach and Colon Cancer Patients Receiving Chemotherapy: Finding from a Quasi-Experiment in Vietnam

Background: Evidence on the effects of nutritional interventions on gastrointestinal cancer patients receiving chemotherapy is not well documented. This study aims to assess the effects of nutritional intervention in patients diagnosed with stomach and colon cancer receiving chemotherapy in Vietnam. Methods: A quasi-experiment with intervention and control groups for pre- and post-intervention was carried out in cancer patients receiving chemotherapy in a university hospital in Vietnam. Patients in the intervention group were provided nutritional counseling, personalized specific dietary advice, and received oral nutrition supplements (ONSs) while patients in the control group only received nutrition counseling. Results: The weight in the intervention and control group after 2 months increased significantly by 1.4 ± 2.6 kg and 0.4 ± 2.3 kg, respectively. Muscle mass increased by 1.2 ± 4.1 cm in the intervention group, while those in the control group decreased by 0.55 ± 2.77 cm. There was no statistical significance between two groups after intervention in terms of Mid–Upper Arm Circumference (MUAC) and percentage of fat. The percentage of malnutrition based on the Scored Patient-Generated Subjective Global Assessment (PG-SGA) and Body Mass Index (BMI) declined after the intervention in both groups. According to the average treatment effect on the treated (ATT) using the propensity score matching and DiD method, participants receiving the intervention were more likely to have a higher score of weight (Coef = 0.84; 95%CI = 0.47; 2.16) and muscle mass (Coef = 1.08; 95%CI = 0.09; 2.06) between pre- and post-intervention. By contrast, the PG-SGA scores on treated participants were more likely to decrease after the intervention (Coef = −1.28; 95%CI = −4.39; −0.84). After matching, being female, living in rural areas, or having stomach cancer were still positively related to being moderately/severely malnourished by the PG-SGA, and these findings were statistically significant (p < 0.05). Conclusion: The nutritional interventions had a positive effect on weight gain, muscle mass, and reduced malnutrition. Further studies with a longer follow-up duration are needed to confirm the effects of the intervention.

Diagnostic Performance of SGA, PG-SGA and MUST for Malnutrition Assessment in Adult Cancer Patients: A Systematic Literature Review and Hierarchical Bayesian Meta-Analysis

Because cancer-associated malnutrition is a major health complication, timely nutritional screening is of utmost importance. The aim of this study was to conduct a systematic literature review and meta-analysis of three tools in order to identify the method with the best diagnostic performance. PubMed, EMBASE and Cochrane central register of controlled trials were searched for articles published from database inception to January 2021. Studies that assessed the diagnostic accuracy of the SGA, PG-SGA or MUST in adult cancer patients were included. In order to evaluate the quality of each included study, the QUADAS-2 tool was used after which a meta-analysis was conducted using the hierarchical bivariate model. This model accounts for both within and between study variability. 16 studies (18 datasets) were included to evaluate these tools. The overall sensitivity and specificity for SGA was 0.69 and 0.80, 0.95 and 0.81 for PG-SGA, along with 0.83 and 0.83 for MUST respectively. An assessment of the likelihood ratios showed that PG-SGA had the highest LR + and the lowest LR-, it therefore has the best diagnostic performance to confirm malnutrition in adult cancer patients.
