Malnutrition assessment in patients with cancers of the head and neck: A call to action and consensus

Effect of nonpharmacological interventions on nutrition status, complications and quality of life in head and neck cancer patients undergoing radiotherapy: A systematic review and meta-analysis

PURPOSE

To evaluate the effect of nonpharmacological therapies on nutrition status, complications and quality of life in head and neck cancer patients and to provide a basis for clinical practice.

METHODS

This systematic review was reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis statement. Ten databases were systematically searched for all available articles from construction to November 2023. Two researchers independently conducted literature screening, data extraction and quality evaluation. Cochrane Review Manager 5.3 was used for meta-analysis.

RESULTS

Finally, 27 RCT studies including 2814 patients with head and neck cancer were included. Five categories of interventions were used: nutritional support, exercise, swallowing function training, psychological intervention and low-level laser therapy. Nonpharmacological interventions can improve body weight loss in patients with HNC at the end of treatment (MD: 1.66 kg; 95% CI: 0.80 to 2.51), and subgroup analysis showed that nutritional support, psychological intervention and low-level laser therapy were effective. Nonpharmacological interventions can also ameliorate decreases in BMI (MD: 0.71; 95% CI: 0.16 to 1.26) and reduce the incidence of malnutrition (RR: 0.76; 95% CI: 0.67 to 0.86), oral mucositis (RR: 0.54; 95% CI: 0.37 to 0.80) and gastrointestinal complications (RR: 0.61; 95% CI: 0.38 to 0.96) during radiotherapy; however, no significant differences were found in other complications and quality of life.

CONCLUSION

Nonpharmacological interventions can improve the nutrition status of patients with head and neck cancer and reduce the incidence of severe oral mucositis and gastrointestinal complications during radiotherapy but have no significant impact on quality of life.

Predictive Factors for Critical Weight Loss in Saudi Head and Neck Cancer Patients Undergoing (Chemo)Radiotherapy

Weight loss is a significant health problem among patients with head and neck cancer (HNC) that is attributable primarily to the tumor or tumor therapy. Critical weight loss (CWL) is defined as the unintentional loss of ≥5% of weight. Therefore, this study's goal was to investigate and determine the possible factors influencing CWL among patients with HNC who have received radiotherapy or concurrent chemoradiotherapy (CCRT). We conducted a retrospective analysis of 175 patients who received radiotherapy or CCRT as either their primary, adjuvant, or combined treatment at the Oncology Center in King Abdullah Medical City. All patients were ≥18 years of age and diagnosed with HNC with no metastasis. The study results showed that 107 patients (61%) had CWL, while 68 (39%) did not. The following factors were significantly predictive of CWL with a multivariate regression analysis: pretreatment BMI (AOR = 1.1, 95% CI = 1.02-1.17), oral cavity cancer (AOR = 10.36, 95% CI = 1.13-94.55), and male sex (AOR = 3.15, 95% CI = 1.39-7.11). In conclusion, weight loss is highly prevalent among HNC patients during treatment. Accordingly, pretreatment BMI, cancer in the oral cavity, and being male can be considered predictive factors for CWL.

Oropharyngeal dysphagia and cachexia: Intertwined in head and neck cancer

BACKGROUND

This study aims to investigate the relationship between cancer cachexia and oropharyngeal dysphagia (OD) in patients with head and neck cancer (HNC) prior to chemoradiotherapy or bioradiotherapy (CRT/BRT).

METHODS

A prospective cohort study with patients with HNC undergoing CRT/BRT (2018-2021) was conducted. Body composition and skeletal muscle function were evaluated using bioelectrical impedance analysis, handgrip strength, and the short physical performance battery (SPPB). The M. D. Anderson Dysphagia Inventory (MDADI), Eating Assessment Tool (EAT)-10 questionnaire, and patient characteristics were collected. A standardized videofluoroscopic swallowing study was offered to patients.

RESULTS

Sixty-six patients were included. Twenty-six patients scored EAT-10 ≥ 3 and seventeen were cachectic. ACE-27 score >1, cachexia, abnormal SPPB-derived repeated chair-stand test, lower MDADI scores, and higher overall stage grouping showed potential predictive value (p ≤ 0.10) for EAT-10 ≥ 3. Using multivariable regression analysis, only cachexia remained a significant predictor of EAT-10 ≥ 3 (HR 9.000 [95%CI 2.483-32.619], p = 0.001).

CONCLUSION

Cachexia independently predicted the presence of patient-reported OD.

Effect of Oral Nutritional Supplements on Patients with Esophageal Cancer During Radiotherapy

Background: This study investigated the effect of oral nutritional supplements (ONS) on patients with esophageal cancer during radiotherapy. Materials and Methods: Patients with esophageal cancer undergoing radiotherapy were randomly divided into nutritional intervention (NI) and routine treatment (RT) groups. All patients received one-on-one nutritional counseling and dietary advice, and patients in the NI group received ONS. Body mass index (BMI), a patient-generated subjective global assessment (PG-SGA), serum albumin (ALB), hemoglobin (Hb), white blood cell (WBC) count, prealbumin (PA), and platelets (PLTs) were recorded before and after radiotherapy in both the NI group and the RT group. Further, the adverse reactions during the treatment were evaluated. Results: In the NI group, the BMI after radiotherapy was significantly higher than that before radiotherapy, and the PG-SGA score after radiotherapy was significantly lower than that before radiotherapy (p < 0.05). In the RT group, the levels of BMI, Hb, ALB, PA, PLTs, and WBC after radiotherapy were significantly lower than those before radiotherapy, and the PG-SGA score was worse after radiotherapy (p < 0.05). After radiotherapy, the levels of BMI, Hb, ALB, and PA in the NI group were similar to those in the RT group (p > 0.05); whereas the levels of WBC and PLTs in the NI group were lower than those in the RT group (p < 0.05). During the treatment, the toxic reactions of radiation esophagitis, myelosuppression, nausea, and vomiting were decreased in the NI group compared with the RT group. Conclusions: ONS can reduce weight loss and improve the nutritional status of patients with esophageal cancer during radiotherapy.

A Multi-Site, International Audit of Malnutrition Risk and Energy and Protein Intakes in Patients Undergoing Treatment for Head Neck and Esophageal Cancer: Results from INFORM

Patients with foregut tumors are at high risk of malnutrition. Nutrition care focuses on identifying individuals at risk of malnutrition and optimizing nutrient intake to promote the maintenance of body weight and lean body mass. This multi-center prospective, longitudinal study audited nutrition care practices related to screening for risk of malnutrition (Patient-Generated Subjective Global Assessment Short Form; PG-SGA SF), and nutrition interventions prescribed (route; adequacy of energy and protein intakes). Audits occurred at four time periods: baseline (before treatment) and at 2, 4, and 6 months after starting cancer treatment; 170 patients (esophageal (ESO; n = 51); head and neck (HN; n = 119)) were enrolled. Nutrition risk (PG-SGA SF score ≥ 4) was prevalent at every time period: HN (baseline: 60%; 6 months 66%) and ESO (77%; 72%). Both groups had significant (p < 0.001) weight losses over the 6 month audit period (HN = 13.2% ESO = 11.4%). Enteral nutrition (EN) was most likely to be prescribed at 2 months for HN and at 4 and 6 months for ESO. Target prescribed energy and protein intakes were not met with any nutrition intervention; although adequacy was highest for those receiving EN. Nutrition care practices differed for HN and ESO cancers and there may be time points when additional nutrition support is needed.

Pretreatment Glasgow Prognostic Score Correlated with Serum Histidine Level and Three-Year Mortality of Patients with Locally Advanced Head and Neck Squamous Cell Carcinoma and Optimal Performance Status

Few prospective cohort trials have investigted the effect of pretreatment nutritional and inflammatory status on the clinical outcome of patients with cancer and optimal performance status and assessed the interplay between nutrition, inflammation, body composition, and circulating metabolites before treatment. Here, 50 patients with locally advanced head and neck squamous cell carcinoma (LAHNSCC) and Eastern Cooperative Oncology Group performance status (ECOG PS) ≤ 2 were prospectively recruited along with 43 healthy participants. Before concurrent chemoradiotherapy, compared with healthy controls, the cancer group showed lower levels of histidine, leucine, and phenylalanine and had low values in anthropometric and body composition measurements; however, the group displayed higher ornithine levels, more malnutrition, and severe inflammation. Pretreatment advanced Glasgow prognostic score (1 and 2) status was the sole prognostic factor for 3-year mortality rate and was associated with age and serum histidine levels in patients with cancer. Thus, even at the same tumor stage and ECOG PS, patients with LAHNSCC, poor nutrition, and high inflammation severity at baseline may have inferior survival outcomes than those with adequate nutrition and low inflammation severity. Assessment of pretreatment nutritional and inflammatory status should be included in the enrollment criteria in future studies.

Inflammation Status and Body Composition Predict Two-Year Mortality of Patients with Locally Advanced Head and Neck Squamous Cell Carcinoma under Provision of Recommended Energy Intake during Concurrent Chemoradiotherapy

Only few prospective cohort trials have evaluated the risk factors for the 2-year mortality rate between two patient subgroups with locally advanced head and neck squamous cell carcinoma (LAHNSCC): oral cavity cancer with adjuvant concurrent chemoradiotherapy (CCRT) (OCC) and non-oral cavity cancer with primary CCRT (NOCC), under the recommended calorie intake and investigated the interplay among calorie supply, nutrition–inflammation biomarkers (NIBs), and total body composition change (TBC), as assessed using dual-energy X-ray absorptiometry (DXA). Patients with LAHNSCC who consumed at least 25 kcal/kg/day during CCRT were prospectively recruited. Clinicopathological variables, blood NIBs, CCRT-related factors, and TBC data before and after treatment were collected. Factor analysis was performed to reduce the number of anthropometric and DXA-derived measurements. Cox proportional hazards models were used for analysis. We enrolled 123 patients with LAHNSCC (69 with OCC and 54 with NOCC). The mean daily calorie intake correlated with the treatment interval changes in total body muscle and fat. Patients consuming ≥30 kcal/kg/day had lower pretreatment levels but exhibited fewer treatment interval changes in anthropometric and DXA measurements than patients consuming <30 kcal/kg/day. In the multivariate analysis of the 2-year mortality rate, the prognostic influence of the recommended calorie intake could not be confirmed, but different risk factors (performance status, pretreatment platelet-to-lymphocyte ratio, and treatment interval body muscle changes in patients with OCC; age, pretreatment neutrophil-to-lymphocyte ratio, and body fat storage in patients with NOCC) showed independent effects. Therefore, the inflammation status and body composition, but not the recommended calorie supply, contribute to the 2-year mortality rate for patients with LAHNSCC receiving CCRT.

Weight Loss in Post-Chemoradiotherapy Head and Neck Cancer Patients

Background: Weight loss is well-known among head and neck (HNC) patients during radiotherapy and could continue after the treatment is completed. Weight monitoring is essential for treatment outcomes and cancer surveillance. The purpose of the study is to evaluate the weight loss during and post-treatment among HNC patients. Methods: A total of 45 out of 50 patients post-treatment were included in this secondary treatment. Data were collected at baseline, at the completion of radiotherapy and one month after completion of radiotherapy. Results: The mean weight loss was 4.53 ± 2.87 kg (7.4%) during treatment and 1.38 ± 2.65 kg (2.1%) post-treatment. There were significant improvements one month after completion of radiotherapy in Patient-Generated Subjective Global Assessment (PGSGA), muscle mass, nutrition impact symptoms (NIS) score, energy and protein from oral intake (p < 0.0001). Energy and protein from oral nutritional supplements (ONS) decreased significantly (p < 0.0001). Conclusions: The results of this study underline the importance of early identification and monitoring post-treatment in HNC patients. The post-treatment recovery stage is very important for HNC patients to ensure a healing process.

Sarcopenia at the infrahyoid level as a prognostic factor in patients with advanced-stage non-virus-related head and neck carcinoma

PURPOSE

The purpose of this study was to assess whether the infrahyoid skeletal muscle index (IHSMI) can be used instead of the L3 skeletal muscle index (L3SMI) to define sarcopenia and predict prognosis in patients with locally advanced head and neck squamous cell carcinoma (LHNSCC).

METHODS

Patients treated for LHNSCC between January 2009 and April 2018 were assessed. The muscular area at the L3 transverse process and infrahyoid was contoured on absorption-corrected computed tomography prior to treatment. Sarcopenia based on L3SMI (S-L) was defined as values of < 52.4 cm²/m² for men and < 38.5 cm²/m² for women. Sarcopenia based on IHSMI (S-I) was determined via receiver operating curve analysis. Overall survival (OS) and cause-specific survival (CSS) curves were constructed using the Kaplan-Meier method.

RESULTS

In total, 101 patients were analyzed. The median follow-up period was 19 months (range 3-101 month). S-L and S-I were identified in 74 (73.3%) and 56 patients (55.4%), respectively. The 5-year OS rate did not differ between patients with and without S-L (64.9% vs. 79.2%, p = 0.635), whereas the rate was lower in patients with S-I than without S-I (57.1% vs. 93.0%, p = 0.006). Similarly, the 5-year CSS rate did not differ between patients with and without S-L (77.0% vs. 82.3%, p = 0.523), but the rate was lower in patients with S-I (61.2% vs. 93.0%, p = 0.02).

CONCLUSION

Pretreatment S-I, but not S-L, was a good predictor of OS and CSS in patients with LHNSCC.

Concurrent Chemoradiotherapy Induces Body Composition Changes in Locally Advanced Head and Neck Squamous Cell Carcinoma: Comparison between Oral Cavity and Non-Oral Cavity Cancer

Few prospective cohort trials have evaluated the difference in treatment-interval total body composition (TBC) changes assessed by dual-energy X-ray absorptiometry (DXA) between two patient subgroups with locally advanced head and neck squamous cell carcinoma (LAHNSCC) receiving concurrent chemoradiotherapy (CCRT): oral cavity cancer with adjuvant CCRT (OCC) and non-oral cavity with primary CCRT (NOCC). This study prospectively recruited patients with LAHNSCC. Clinicopathological variables, blood nutritional/inflammatory markers, CCRT-related factors, and TBC data assessed by DXA before and after treatment were collected. Multivariate linear regression analysis identified the factors associated with treatment-interval changes in body composition parameters, including lean body mass (LBM), total fat mass (TFM), and bone mineral content (BMC). A total of 127 patients (OCC (n = 69) and NOCC (n = 58)) were eligible. Body composition parameters were progressively lost during CCRT in both subgroups. Extremities lost more muscle mass than the trunk for LBM, whereas the trunk lost more fat mass than the extremities for TFM. BMC loss preferentially occurred in the trunk region. Different factors were independently correlated with the interval changes of each body composition parameter for both OCC and NOCC subgroups, particularly mean daily calorie intake for LBM and TFM loss, and total lymphocyte count for BMC loss. In conclusion, treatment-interval TBC changes and related contributing factors differ between the OCC and NOCC subgroups.

Comorbidity, Radiation Duration, and Pretreatment Body Muscle Mass Predict Early Treatment Failure in Taiwanese Patients with Locally Advanced Oral Cavity Squamous Cell Carcinoma after Completion of Adjuvant Concurrent Chemoradiotherapy

Few prospective cohort trials have evaluated the potential risk factors of early treatment failure of locally advanced oral cavity squamous cell carcinoma (LAOCSCC) patients following the completion of postoperative adjuvant concurrent chemoradiotherapy (CCRT). We collected clinicopathological variables, nutrition-inflammatory markers and total body composition data assessed by dual-energy X-ray absorptiometry (DXA) before and after CCRT. A factor analysis was used to reduce the number of DXA-derived parameters. Cox proportional hazard models were applied to determine the risk factors associated with early treatment failure defined as tumor progression or death within 180 days of CCRT completion. A total of 69 patients were eligible for analysis. After CCRT, the body weight, body mass index, nutritional markers, and muscle mass decreased, whereas C-reactive protein level increased. Five factors reflecting different body composition statuses were identified. A total of 21 patients (30.4%) developed early treatment failure. Comorbidities (hazard ratio ((HR)), 2.699; 95% confidence interval ((CI)), 1.005–7.913; p = 0.044), radiation duration (HR, 1.092; 95% CI, 1.015–1.174; p = 0.018) and the pretreatment body muscle mass (HR, 0.578; 95% CI, 0.345–0.957; p = 0.037) independently contributed to early treatment failure. Comorbidities, longer radiation duration, and lower pretreatment body muscle mass are predictive factors for early treatment failure in LAOCSCC patients following postoperative adjuvant CCRT completion.

Cost-effectiveness analysis of oral nutritional supplements with nutritional counselling in head and neck cancer patients undergoing radiotherapy

OBJECTIVE

There is limited evidence regarding the economic effects of nutrition support in cancer patients. This study aims at investigating the cost-effectiveness profile of systematic oral nutritional supplementation (ONS) in head and neck cancer (HNC) patients undergoing radiotherapy (RT) and receiving nutritional counseling.

METHODS

A cost-effectiveness analysis based on a RCT was performed to estimate direct medical costs, life years gained (LYG) and Quality-Adjusted Life Years (QALY) for nutritional counseling with or without ONS at 5-month and 6-year follow up time. Value of information analysis was performed to value the expected gain from reducing uncertainty through further data collection.

RESULTS

ONS with nutritional counseling produced higher QALY than nutritional counseling alone (0.291 ± 0.087 vs 0.288 ± 0.087), however the difference was not significant (0.0027, P = 0.84). Mean costs were €987.60 vs €996.09, respectively in the treatment and control group (-€8.96, P = 0.98). The Incremental Cost Effectiveness Ratio (ICER) was -€3,277/QALY, with 55.4% probabilities of being cost-effective at a cost-effectiveness threshold of €30,000/QALY. The Expected Incremental Benefit was €95.16 and the Population Expected Value of Perfect Information was €8.6 million, implying that additional research is likely to be worthwhile. At a median 6-year follow up, the treatment group had a significantly better survival rate when adjusting for late effect (P = 0.039).

CONCLUSION

Our findings provide the first evidence to inform decisions about funding and reimbursement of ONS in combination with nutritional counseling in HNC patients undergoing RT. ONS may improve quality of cancer care at no additional costs, however further research on the cost-effectiveness of nutritional supplementation is recommended.

Malnutrition screening in head and neck cancer patients with oropharyngeal dysphagia

BACKGROUND & AIMS

Malnutrition in head and neck cancer (HNC) patients is associated with increased morbidity and mortality. The purpose of this study is two-fold: to identify the risk of malnutrition in patients with oropharyngeal dysphagia (OD) secondary to HNC, and to determine the relationship between the risk of malnutrition versus tumor characteristics, treatment modality, time interval (between the end of oncological treatment and swallowing assessment date), level of oral intake, body mass index (BMI), aspiration, pharyngeal pooling, and OD-related quality of life (QoL).

METHODS

The Short Nutritional Assessment Questionnaire (SNAQ) was used to screen patients for the risk of malnutrition. Patients underwent a standardized swallowing examination protocol including an endoscopic evaluation of swallowing.

RESULTS

Seventy-five dysphagic HNC patients were included. Forty-eight percent of the patients presented a high risk of malnutrition using SNAQ. The majority of the patients (81.3%) was on a total oral diet. Moreover, BMI did not appear to be a reliable measure to screen for malnutrition as a normal BMI was often associated with an increased risk of malnutrition on the SNAQ. In contrast, patients who were underweight or overweight did not show an association with a high risk of malnutrition. With the exception of BMI, no other patient and tumor characteristics were found to be associated with the risk of malnutrition.

CONCLUSIONS

This study emphasizes the importance of early nutritional screening in dysphagic HNC patients, as almost half of these patients presented a high risk of malnutrition. Malnutrition screening using SNAQ can identify HNC patients with OD who are at risk of malnutrition and subsequently need to be referred to a dietician for additional nutritional assessment, diagnosis of malnutrition, and nutritional support, even when their BMI is within normal range.

A comparison of the MNA-SF, MUST, and NRS-2002 nutritional tools in predicting treatment incompletion of concurrent chemoradiotherapy in patients with head and neck cancer

BACKGROUND

Concurrent chemoradiotherapy (CCRT) treatment incompletion is a known negative prognosticator for patients with head and neck cancer (HNC). Malnutrition is a common phenomenon which leads to treatment interruption in patients with HNC. We aimed to compare the performance of three nutritional tools in predicting treatment incompletion in patients with HNC undergoing definitive CCRT.

MATERIAL AND METHODS

Three nutritional assessment tools, Mini Nutritional Assessment-Short Form (MNA-SF), Malnutritional Universal Screening Tool (MUST), and Nutritional Risk Screening 2002 (NRS-2002), were prospectively assessed prior to CCRT for HNC patients. Patients were stratified into either normal nutrition or malnourished groups using different nutrition tools. Treatment incompletion and treatment-related toxicities associated with CCRT were recorded.

RESULTS

A total of 461 patients were included in the study; malnourished rates ranged from 31.0 to 51.0%. The CCRT incompletion rates were 4.9-6.3% and 14.5-18.2% for normal nutrition patients and malnourished patients, respectively. The tools had significant correlations with each other (Pearson correlation 0.801-0.837, p<0.001 for all) and accurately predicted the incompletion of CCRT. MNA-SF had the highest performance in predicting treatment-related toxicity, including emergency room visits, need for hospitalization, any grade III or higher hematological adverse events, and critical body weight loss, compared to the other tools.

CONCLUSIONS

MNA-SF, MUST, and NRS2002 were all shown to be competent tools for prediction of treatment incompletion and treatment-related toxicity in HNC patients undergoing CCRT. We suggest implementing nutritional assessment prior to treatment to improve the rate of treatment completion and to reduce treatment-related toxicity in HNC patients.

Role of the Appendicular Skeletal Muscle Index for Predicting the Recurrence-Free Survival of Head and Neck Cancer

Background: This study investigates whether the appendicular skeletal muscle index (ASMI) was an independent prognostic predictor for patients with locally advanced head and neck cancer (LAHNC) receiving concurrent chemoradiotherapy (CCRT) and whether there were any differences in lean mass loss in different body regions during CCRT. Methods: In this prospective study, we analyzed the clinicopathological variables and the total body composition data before and after treatment. The factors associated with the 2-year recurrence-free survival rate (RFSR) were analyzed via logistic regression analysis. Results: A total of 98 patients were eligible for analysis. The body weight, body mass index, and all parameters of body composition significantly decreased after CCRT. The pretreatment ASMI was the only independent prognostic factor for predicting the 2-year RFSR (hazard ratio, 0.235; 95% confidence interval, 0.062–0.885; p = 0.030). There was at least 5% reduction in total lean and fat mass (p < 0.001); however, the highest lean mass loss was observed in the arms (9.5%), followed by the legs (7.2%), hips (7.1%), waist (4.7%), and trunk (3.6%). Conclusions: The pretreatment ASMI was the only independent prognostic predictor for the 2-year RFSR of LAHNC patients undergoing CCRT. Asynchronous loss of lean mass may be observed in different body parts after CCRT.

Nurses' Knowledge in Relation to the Anorexia-Cachexia Syndrome in Cancer Patients: A Cross-National Comparison in Two European Countries

INTRODUCTION

The Anorexia-Cachexia Syndrome (ACS) is a severe complication of cancer and is considered to be a significant cause of morbidity and mortality affecting up to two-thirds of cancer patients and one that needs specialized nursing care. Studies showed that the ACS has been relatively under-researched and under-resourced whist the nurses' knowledge has not been systematically explored.

OBJECTIVE

Τo explores nurses' knowledge, understanding, and management of ACS in clinical practice in two European countries.

METHODS

Descriptive-comparative study with 197 cancer nurses recruited during two National Conferences in Greece and Cyprus. Data were retrieved with the "Investigation of anorexia-cachexia syndrome in Practice" questionnaire.

RESULTS

In terms of nurses' perceptions on ACS, the prevailing characteristic reported in both countries was anorexia (p = .65) followed by weight loss (p = .04). 189 nurses (95.9%, p = .176) do not currently use a tool to assess patients' nutritional status as part of their standard clinical practice. Statistically significant differences were found in relation to the routine assessment of nutritional-related symptoms including early satiety (Cyprus 64% vs. Greece 37%, p = .001), hiccough (66% vs. 36%, p < .001), alteration of the taste/odor sensation (77% vs. 45%, p < .001), problems in the oral cavity (84% vs. 68%, p = .032) and daily activities (85% vs. 69%, p = .032). The priority level for the ACS management differed significantly in the two countries (p = .006), with higher priority being reported in Cyprus.

CONCLUSION

The study showed that more education is needed for cancer nurses to better understand the ACS which can facilitate the better management of the syndrome in clinical practice.

A National Evaluation of Food Insecurity in a Head and Neck Cancer Population

OBJECTIVES/HYPOTHESIS

To determine the food security status of patients with a history of head and neck cancer and compare to other types of cancer.

STUDY DEIGN

A retrospective analysis using the National Health Interview Series.

METHODS

The National Health Interview Series (NHIS) for the calendar years 2014 to 18 was used to elicit food security status (secure, marginally secure/not secure) among adult patients with a history of throat/pharynx head and neck cancer (pHNC), thyroid cancer, and colon cancer. The relationship between food security and the primary site was compared and subanalyses were performed according to sex, race, and ethnicity.

RESULTS

The study population included 199.0 thousand patients with pHNC, with 17.7% (95% confidence interval, 10.5%-28.1%) of pHNC patients reporting their food security status as marginally secure or not secure. Food insecurity was significantly higher among pHNC patients when compared to thyroid cancer (insecurity 10.7%, [7.7%-14.7%]) and colon cancer patients (10.1%, [7.8%-13.2%]). Among pHNC patients, there was no significant difference in rates of food insecurity when stratified by gender, race, or ethnicity. However, black individuals were more likely to have food insecurity with a history of thyroid or colon cancer (P < .042) and Hispanics were more likely to have food insecurity with a history of thyroid cancer (P = .005).

CONCLUSIONS

Food insecurity disproportionally affects patients with a history of pHNC, though there is less demographic variability when compared to other cancer primary sites. Food security assessments should be part of the tailored approach to survivorship management in head and neck cancer.

Mapping impact factors leading to the GLIM diagnosis of malnutrition in patients with head and neck cancer

BACKGROUND & AIMS

In head and neck cancer, the combination of weight loss and elevated C-reactive protein levels means that patients have malnutrition as defined by the Global Leadership Initiative on Malnutrition (GLIM). This study aimed to identify impact factors for malnutrition as defined by the GLIM criteria among patients with head and neck cancer at the start of treatment and up to 12 months post-treatment.

METHODS

In a prospective, observational study, patient, tumour, treatment, and nutritional data from 229 patients with head and neck cancer were collected at the start of treatment and at three follow-ups (7 weeks after the start of treatment and at 3 and 12 months after the termination of treatment). These clinical variables were statistically analysed in relation to malnutrition at each follow-up using univariate and multivariate analyses. Malnutrition was defined according to the two GLIM criteria of >5% body weight loss during the last 6 months and C-reactive protein >5 mg/L.

RESULTS

The following factors were predictive for malnutrition in the multivariate analysis performed 7 weeks after the start of treatment: moderate or severe mucositis, chemoradiotherapy ± surgery, and the need for nutritional support (total or partial use of tube feeding/parenteral nutrition). Advanced tumour stage (III-IV) was significant for malnutrition at the start of treatment and at the 7 week and 3 month follow-ups, but not at 12 months.

CONCLUSIONS

Severe mucositis, chemoradiotherapy ± surgery, and advanced tumour stage were found to be impact factors for the diagnosis of malnutrition using GLIM at different follow-up times from the start of treatment up to 12 months after the end of treatment. Few patients with head and neck cancer are diagnosed with malnutrition according to the GLIM criteria in a long-term perspective after the termination of treatment. Research on the validity of the GLIM criteria is needed to build a comprehensive evidence base of impact factors for malnutrition in head and neck cancer.

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.

Oral Nutritional Supplementation Affects the Dietary Intake and Body Weight of Head and Neck Cancer Patients during (Chemo) Radiotherapy

Considering the symptoms of (chemo) radiotherapy and the reduction in food intake in head and neck cancer (HNC) patients, this study aimed to investigate the association between treatment time points and oral nutritional supplementation (ONS) on dietary intake to estimate the frequency of energy and nutrient inadequacy, and also to evaluate body weight changes (BWC). Dietary intake data of 65 patients were obtained from 24-h dietary recalls and prevalence of inadequacy was calculated before or at the beginning (T0), in the middle (T1), and at the end of treatment (T2). BWC were calculated as the weight difference considering the previous weight reported and/or measured. Energy and macronutrient intake decreased in T1 and then improved in T2 (p < 0.001 for both). Micronutrient intake increased during treatment due to ONS use, but still presented a high probability of inadequate intake. In particular, calcium, magnesium, and vitamin B6 showed almost 100% of probability of inadequacy for those who did not use ONS. Finally, overweight patients suffered a higher weight accumulated deficit with a delta of −15 kg compared to other BMI (body mass index) categories. Therefore, we strongly recommend initiating nutritional counseling in conjunction with prophylactic ONS prescription from diagnosis to adjust nutrient intake and minimize weight loss.

A prospective nutritional assessment using Mini Nutritional Assessment-short form among patients with head and neck cancer receiving concurrent chemoradiotherapy

BACKGROUND

No gold standard of nutritional assessment is established among patients with head and neck cancer (HNC) receiving concurrent chemoradiotherapy (CCRT). This study aimed to evaluate the clinical significance of pre-treatment nutritional status using the Mini Nutritional Assessment-short form (MNA-SF) among HNC patients receiving CCRT.

METHODS

A total of 461 consecutive patients with newly diagnosed HNC treated with definitive CCRT at three medical institutes were prospectively enrolled. Nutritional status was assessed using MNA-SF within 7 days before CCRT initiation. Patients were classified as having normal nutrition, at risk of malnutrition, and malnourished groups according to MNA-SF for comparison.

RESULTS

The 1-year overall survival rates were 89.8%, 76.8%, and 67.7% in the normal nutrition, at risk of malnutrition, and malnourished groups, respectively. Patients with normal nutrition had significantly lower rates of uncompleted radiotherapy and chemotherapy (4.5% and 4.1%, respectively) compared with patients at risk for malnutrition (14.1% and 11.5%, respectively) and those malnourished (11.1% and 11.1%, respectively). Patients with normal nutrition had significantly lower treatment-related complication rates regarding emergency room visits, hospital admission, and need for tubal feeding than those with at risk of malnutrition and malnourished. Patients with normal nutrition had significantly fewer severe hematologic toxicities (p = 0.044) and severe non-hematologic toxicities (p = 0.012) of CCRT than those malnourished.

CONCLUSION

Pre-CCRT nutritional status identifies HNC patients vulnerable to treatment interruption and treatment complications. We suggest that nutritional assessment with MNA-SF should be incorporated in pre-CCRT evaluation for all HNC patients.

Evaluation of preventive laser photobiomodulation in patients with head and neck cancer undergoing radiochemotherapy: Laser in patients with head and neck cancer

AIMS

This study aimed to evaluate the effect of laser photobiomodulation in the prevention of oral mucositis (OM), salivary hypofunction and referred pain in patients with head and neck cancer.

METHODS AND RESULTS

This randomized clinical study divided patients into two groups: the laser group (LG, n = 30) and the control group (CG, n = 24). The LG (InGaAlP, 660 nm, 86.7 mW, 2 J/cm² ) participated in the preventive protocol, while the CG underwent a simulated procedure without light emission. The degree of OM, salivary flow, and referred pain were evaluated at five different periods of radiotherapy. Both groups showed a significant increase in the degree of OM (P < .01). Regarding OM, salivary flow, and oral pain, there were no significant differences between the groups.

CONCLUSIONS

The laser photobiomodulation protocol used in this study was not effective in preventing radiochemotherapy-induced OM, salivary hypofunction, and referred pain in patients with head and neck cancer. Notably, although the development of OM did not differ significantly according to the use of laser therapy, the severity of oral mucositis was reduced in patients who underwent laser therapy compared to that in patients who did not.

Determining Malnutrition Assessment Criteria to Predict One-Year Mortality for Locally Advanced Head and Neck Cancer Patients Undergoing Concurrent Chemoradiotherapy

Study on the impact of pretreatment malnutrition on treatment outcomes in locally advanced head and neck cancer (LAHNC) patients is still lacking. We prospectively collected various malnutrition assessment methods including nutrition indexes, inflammatory biomarkers, and lean body mass index (LBMI) data before treatments. The one year mortality rate was assessed, and the factors associated with this outcome were investigated. Furthermore, the association between malnutrition assessment methods was examined. A total of 113 patients were enrolled. By prognostic stratification based on the prognostic nutritional index (PNI) and platelet-to-lymphocyte ratio (PLR) combination, the low PNI/high PLR group had highest and the high PNI/low PLR group had the lowest mortality rate. Furthermore, the PNI was positively correlated with the LBMI, and the PLR was inversely correlated with the LBMI. PNI and PLR were found to be independent prognostic factors of one year mortality and also associated with the loss of muscle.

Can Bioelectrical Impedance Analysis and BMI be a Prognostic Tool in Head and Neck Cancer Patients? A Review of the Evidence

Background: Malnutrition can significantly affect disease progression and patient survival. The efficiency of weight loss and bioimpedance analysis (BIA)-derived measures in the evaluation of malnutrition, and disease progression and prognosis in patients with head and neck cancer (HNC) are an important area of research. Method: The PubMed database was thoroughly searched, using relative keywords in order to identify clinical trials that investigated the role of BIA-derived measures and weight loss on the disease progression and prognosis of patients with HNC. Twenty-seven studies met the criteria. More specifically, six studies examined the prognostic role of the tissue electrical properties in HNC patients; five examined the role of the tissue electrical properties on identifying malnutrition; four studies looked at the changes in the tissue electrical properties of HNC patients; and 12 examined the prognostic role of weight loss on survival and/or treatment outcomes. Results: Several studies have investigated the role of nutritional status tools on prognosis in HNC patients. Current studies investigating the potential of BIA-derived raw data have shown that phase angle (PA) and capacitance of the cell membrane may be considered prognostic factors of survival. Weight loss may be a prognostic factor for treatment toxicity and survival, despite some conflicting evidence. Conclusions: Further studies are recommended to clarify the role of BIA-derived measures on patients’ nutritional status and the impact of PA on clinical outcomes as well as the prognostic role of weight loss.

Impact of nutritional status at the outset of assessment on postoperative complications in head and neck cancer

OBJECTIVES

Half of the patients presenting with head and neck tumor are malnourished at the outset of treatment. Muscle mass loss (sarcopenia) seems to be critical. The aim of the present study was to assess the impact of nutritional status and sarcopenia on postoperative complications in head and neck cancer.

MATERIALS AND METHODS

A retrospective study for the period November 2014 to May 2016 included 92 patients operated on for head and neck squamous cell carcinoma. Complications at 30 days were graded on the 5-level Clavien-Dindo classification. Nutritional status was assessed anthropometrically (weight), biologically (albuminemia and Nutrition Risk Index (NRI)), on CT (muscle mass index at 3rd lumbar vertebra) and functionally (Short Physical Performance Battery). Assessment was made at the outset of management, and nutritional treatment was initiated as appropriate. Potential risk factors for postoperative complications were assessed: performance status, prior radiation therapy, smoking and alcohol abuse.

RESULTS

54% of patients were malnourished on the NRI. 41% had grade≥2 complications. The most frequent complications were infection and healing disorder. The risk of complications was higher in case of malnutrition (62% vs. 17%; P<0.001) and sarcopenia (56% vs. 22%; P<0.01), with 50% longer hospital stay (P=0.04).

CONCLUSION

Malnutrition and sarcopenia are independent risk factors for postoperative complications.

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

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

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

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

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

Cancer-Related Fatigue, Laboratory Markers as Indicators for Nutritional Status among Patients with Colorectal Cancer

Our objective was to determine the relationship between cancer-related fatigue (CRF), laboratory markers, and nutritional status among patients with colorectal cancer (CRC). A cross-sectional design was used. A sample of 80 participants diagnosed with CRC participated and completed the study's surveys including the patient-generated subjective global assessment (PG-SGA), cancer fatigue scale (CFS), laboratory markers sheet, and patient-related factors sheet. Positive relationships were identified between PG-SGA and CRF, physical fatigue, cognitive fatigue, WBC, and calcium level (r = 0.781, 0.820, 0.751, 0.680, and 0.710; P = 0.001 respectively). Negative relationships were found between PG-SGA and sodium, potassium, and hemoglobin levels (r = -0.801, -0.761, and -0.810; P = 0.001 respectively). The regression analysis revealed an R₂ = 0.610 (adjusted R₂ = 0.590), F (4.58, P < 0.001). Finally, the above-mentioned independent variables accounted for 61.0% of the variance in PG-SGA. Patients with CRC are experiencing nutritional problems during their treatment. Cancer-related fatigue and other laboratory markers are considered indicators for nutritional status. Clinical dietitians and oncology nurses can work together to monitor these parameters and provide clinical treatment when needed.

Providing care to a family member affected by head and neck cancer: a phenomenological study

BACKGROUND

Cancer is recognized as a family illness as many head and neck cancer (HNC) patients after treatment require assistance from a family caregiver throughout the rest of their life. The purpose of this study was to explore the lived experience of primary family caregivers of HNC patients dealing with laryngectomy regarding their complex supportive role.

METHODS

Phenomenological study based on individual interviews of twelve primary caregivers of HNC patients, recruited by purposeful sampling. Interview contents were analyzed in depth, in accordance with Colaizzi's descriptive analysis framework, to explore and identify significant themes and subthemes.

RESULTS

Analysis evidenced three main topics and subthemes embracing various aspects of the caregiver's lived experiences: (1) experiencing disease and the pathway of care, (2) handling changes to everyday life, and (3) support received by others.

CONCLUSION

Given the essential role the caregiver has in the patient's post-treatment recovery, future planning of HNC patient care must consider the caregivers' needs. In order to guarantee an appropriate and effective health professional care, it is important to consider caregivers' issues and needs as part of HNC patient care planning from the diagnosis to the follow-up.

Prevalence and prognostic significance of malnutrition in patients with cancers of the head and neck

BACKGROUND & AIMS

Head and neck cancer (HNC) are at high nutritional risk; however the prevalence and severity of malnutrition in contemporary patients with HNC are unclear. Diagnostic criteria for cancer-associated weight loss grading (WLG) (Grades 0 to 4) [1] have been validated and are recommended in oncology nutrition clinical practice guidelines [2-3]. The aim was to determine the prevalence using WLG in HNC patients and determine the extent to which reduced dietary intake (DI) explained variation of WLG.

METHODS

A population-based cohort of HNC patients (N = 1756) in northern Alberta, Canada included consecutive new patients, 2004-2016. At referral to the regional cancer center weight history and DI categories were collected. Multinomial logistic regression (MLR) identified predictors of weight loss (WL) severity. Overall survival (OS) in relation to WL Grade and DI was determined by multivariable Cox proportional hazard.

RESULTS

WL was absent in 42.9% and the remainder had Grade 1 (18%), Grade 2 (14.7%), Grade 3 (15.9%) and Grade 4 (8.5%) WL. Independent predictors of WLG in adjusted MLR model, included stage (P < 0.000), performance status (PS) (P < 0.000) and DI categories (P < 0.000); sex, age and disease site were not significant. Compared to "normal food in normal amount" adjusted Odds Ratio for WL Grade 4 was 4.0 (2.1-7.5) "normal food, but less than normal amount"; 25.2 (10.7-59.1) "little solid food"; 51.8 (10.5-255.3) "very little of anything"; 42.4 (11.0-163.0) "only liquids"; 25.9 (7.1-94.3) "only nutritional supplements". In the Cox model controlled for age, sex, cancer stage and site and PS, both WLG ((P < 0.000) and DI categories (P = 0.003) independently predicted OS.

CONCLUSION

Data from this population cohort provide a benchmark for prevalence of cancer associated WL severity at diagnosis. Patient reported DI categories are strong predictors of WL and prognostic for OS.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Comparison of Three Nutritional Screening Tools to Predict Malnutrition Risk and Detect Distinctions Between Tools in Cancer Patients Receiving Radiochemotherapy

The aim of this study was to compare three screening tools for malnutrition in patients with head and neck cancers or central nervous system tumors (CNS) who are undergoing radiochemotherapy. The study evaluated 124 adult cancer patients. The Subjective Global Assessment (SGA), Mini-Nutritional Assessment (MNA), and Nutritional Risk Screening 2002 (NRS-2002) were chosen to assess the risk of malnutrition. The prevalence of patients at nutritional risk was 31% with SGA, 31% with MNA and 23% with NRS-2002 in all patients. The agreement between SGA and MNA was substantial (κ = 0.886, P < 0.001); the agreement between SGA and NRS-2002 was moderate (κ = 0.713, P < 0.001); and the agreement between MNA and NRS-2002 was also moderate (κ = 0.795, P < 0.001). In subgroup analysis, SGA and MNA substantially (κ = 0.973, P < 0.001), SGA and NRS-2002 moderately (κ = 0.722, P < 0.001), and MNA and NRS-2002 moderately (κ = 0.747, P < 0.001) agreed in head and neck cancer patients. In CNS tumor patients, SGA and MNA slightly (κ = 0.390, P = 0.005), SGA and NRS-2002 fairly (κ = 0.457, P =0.001), and MNA and NRS-2002 substantially (κ = 0.878, P < 0.001) agreed. The best agreement in tools was observed between SGA with MNA in all patients. Further studies in different tumor groups will enhance our understanding of current tools for malnutrition detection of radiotherapy patient.

Evaluation of classification and regression tree (CART) model in weight loss prediction following head and neck cancer radiation therapy

OBJECTIVE

We explore whether a knowledge-discovery approach building a Classification and Regression Tree (CART) prediction model for weight loss (WL) in head and neck cancer (HNC) patients treated with radiation therapy (RT) is feasible.

METHODS AND MATERIALS

HNC patients from 2007 to 2015 were identified from a prospectively collected database Oncospace. Two prediction models at different time points were developed to predict weight loss ≥5 kg at 3 months post-RT by CART algorithm: (1) during RT planning using patient demographic, delineated dose data, planning target volume-organs at risk shape relationships data and (2) at the end of treatment (EOT) using additional on-treatment toxicities and quality of life data.

RESULTS

Among 391 patients identified, WL predictors during RT planning were International Classification of Diseases diagnosis; dose to masticatory and superior constrictor muscles, larynx, and parotid; and age. At EOT, patient-reported oral intake, diagnosis, N stage, nausea, pain, dose to larynx, parotid, and low-dose planning target volume-larynx distance were significant predictive factors. The area under the curve during RT and EOT was 0.773 and 0.821, respectively.

CONCLUSIONS

We demonstrate the feasibility and potential value of an informatics infrastructure that has facilitated insight into the prediction of WL using the CART algorithm. The prediction accuracy significantly improved with the inclusion of additional treatment-related data and has the potential to be leveraged as a strategy to develop a learning health system.

Which Assessment Method of Malnutrition in Head and Neck Cancer?

Objective

To assess the value of several diagnostic methods of nutritional status during the initial management of a head and neck cancer.

Study Design

Single-center prospective study.

Setting

Tertiary referral center.

Subjects and Methods

Ninety patients with head and neck cancer participated in the study. Assessment of their nutritional status was made with anthropometric, biological, body, and muscle measurements (the last by computed tomography: L3 muscle mass index [L3MMI]). Assessment of muscle performance (functional reflection of nutritional status) was made via the Short Physical Performance Battery test. The malnutrition thresholds were set according to the literature.

Results

Mean body mass index (BMI) was 24.6 ± 5.4 kg/m2. Mean weight loss and albumin levels were –4.5 ± 10.5 kg and 37.1 ± 5.2 g/L, respectively. Fourteen percent of patients were diagnosed as malnourished on the basis of BMI, 54% according to the Nutritional Risk Index (NRI), and 58% by L3MMI. There was 64% agreement between NRI and L3MMI ( P < .001). All patients identified as malnourished by BMI were considered as such by the other assessment methods; however, many malnourished patients had normal or high BMI. The Short Physical Performance Battery score was low particularly among patients considered to be the most undernourished by the other methods.

Conclusion

NRI and L3MMI are the best methods to identify patients as being malnourished. Functional muscle assessment can determine the severity of malnutrition.

Percutaneous endoscopic gastrostomy feeding of locally advanced oro-pharygo-laryngeal cancer patients: Blenderized or commercial food?

OBJECTIVES

Head and neck cancer patients commonly suffer from severe malnutrition at the time of tentative diagnosis. Percutaneous Endoscopic Gastrostomy [PEG] feeding is now considered as an efficient tool to reduce nutritional deterioration alongside concurrent treatment. We undertook the challenge to retrospectively evaluate the impact of a commercial, disease-specific, feeding formula [Supportan, Fresenius Kabi, Hellas] versus blenderized family food on nutritional outcome.

MATERIALS AND METHODS

This is a retrospective analysis of prospectively collected nutritional and anthropometric data at the time of PEG placement, at the 8th week [after treatment termination] and at 8 months [6mo of recovery from treatment]. All patients were prescribed a commercial feeding formula.

RESULTS

The final dataset included 212 patients: 112 received the commercial formula, 69 voluntarily decided to switch into blenderized-tube-feeding, and 31 were prescribed to receive a home-made formula of standard ingredients. The commercial formula seemed to help patients to fight the catabolism of concurrent treatment, since, at the 8mo assessment, both Body Mass index and Fat Free Mass had almost recovered to the values at the time of first diagnosis. Neither group on blenderized or home-made formulas exhibited nutritional improvement, but experienced a significant deterioration throughout the study period, with the home-made formula group being the worst.

CONCLUSION

These findings clearly indicate that home-made and blenderized foods do not adequately support the nutritional requirements of patients with HNC scheduled to receive concurrent CRT treatment.

Nutritional counseling with or without systematic use of oral nutritional supplements in head and neck cancer patients undergoing radiotherapy

BACKGROUND

To evaluate the benefit of oral nutritional supplements (ONS) in addition to nutritional counseling in head and neck cancer (HNC) patients undergoing radiotherapy (RT).

METHODS

In a single-center, randomized, pragmatic, parallel-group controlled trial (ClinicalTrials.gov: NCT02055833; February 2014-August 2016), 159 newly diagnosed HNC patients suitable for to RT regardless of previous surgery and induction chemotherapy were randomly assigned to nutritional counseling in combination with ONS (N = 78) or without ONS (N = 81) from the start of RT and continuing for up to 3 months after its end. Primary endpoint was the change in body weight at the end of RT. Secondary endpoints included changes in protein-calorie intake, muscle strength, phase angle and quality of life and anti-cancer treatment tolerance.

RESULTS

In patients with the primary endpoint assessed (modified intention-to-treat population), counseling plus ONS (N = 67) resulted in smaller loss of body weight than nutritional counseling alone (N = 69; mean difference, 1.6 kg [95%CI, 0.5-2.7]; P = 0.006). Imputation of missing outcomes provided consistent findings. In the ONS-supplemented group, higher protein-calorie intake and improvement in quality of life over time were also observed (P < 0.001 for all). The use of ONS reduced the need for changes in scheduled anti-cancer treatments (i.e. for RT and/or systemic treatment dose reduction or complete suspension, HR=0.40 [95%CI, 0.18-0.91], P = 0.029).

CONCLUSION

In HNC patients undergoing RT or RT plus systemic treatment, and receiving nutritional counseling, the use of ONS resulted in better weight maintenance, increased protein-calorie intake, improved quality of life and was associated with better anti-cancer treatment tolerance.

Management of Cancer Cachexia and Guidelines Implementation in a Comprehensive Cancer Center: A Physician-Led Cancer Nutrition Program Adapted to the Practices of a Country

CONTEXT

Cancer-associated cachexia is correlated with survival, side-effects, and alteration of the patients' well-being.

OBJECTIVES

We implemented an institution-wide multidisciplinary supportive care team, a Cancer Nutrition Program (CNP), to screen and manage cachexia in accordance with the guidelines and evaluated the impact of this new organization on nutritional care and funding.

METHODS

We estimated the workload associated with nutrition assessment and cachexia-related interventions and audited our clinical practice. We then planned, implemented, and evaluated the CNP, focusing on cachexia.

RESULTS

The audit showed a 70% prevalence of unscreened cachexia. Parenteral nutrition was prescribed to patients who did not meet the guideline criteria in 65% cases. From January 2009 to December 2011, the CNP team screened 3078 inpatients. The screened/total inpatient visits ratio was 87%, 80%, and 77% in 2009, 2010, and 2011, respectively. Cachexia was reported in 74.5% (n = 2253) patients, of which 94.4% (n = 1891) required dietary counseling. Over three years, the number of patients with artificial nutrition significantly decreased by 57.3% (P < 0.001), and the qualitative inpatients enteral/parenteral ratio significantly increased: 0.41 in 2009, 0.74 in 2010, and 1.52 in 2011. Between 2009 and 2011, the CNP costs decreased significantly for inpatients nutritional care from 528,895€ to 242,272€, thus financing the nutritional team (182,520€ per year).

CONCLUSION

Our results highlight the great benefits of implementing nutritional guidelines through a physician-led multidisciplinary team in charge of nutritional care in a comprehensive cancer center.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

A review of weight loss and sarcopenia in patients with head and neck cancer treated with chemoradiation

Background

Concurrent chemotherapy and radiation (CTRT) improves disease-free survival in locally advanced head and neck cancer but is associated with numerous acute and chronic toxicities resulting in substantial alterations in body mass and composition. We aim to summarize the current evidence on body composition changes experienced by patients undergoing CTRT, examine the impact of these changes on clinical outcomes and address potential interventions aimed at mitigating the loss.

Main Body

Loss of 20 % of pre-CTRT weight predicts poorer treatment tolerance and 30-day mortality. While clinical practice focuses on body weight, emerging data indicates that CTRT causes profound adverse changes in lean body mass (sarcopenia). Higher prevalence of sarcopenia predicts poorer disease-free survival as well as overall survival, lower quality of life and functional performance. The magnitude of CTRT-induced sarcopenia is the equivalent to that observed in a decade of aging in a healthy adult. Alterations in body composition are only explained, in part, by decreased caloric intake; other significant predictors include body mass index, stage, and dysphagia. Lifestyle interventions aimed at preventing loss of whole-body and especially lean mass include nutritional counseling, nutritional supplements, dietary supplements and exercise training. Personalized nutritional counseling has been associated with improvement in quality of life, while the benefits of feeding tube placement are inconsistent. There are inconsistently reported benefits of resistance training in this population.

Conclusion

Patients with head and neck cancer undergoing CTRT therapy experience dramatic shifts in body composition, including sarcopenia, which can negatively impact clinical outcomes. Efforts to understand the magnitude, clinical importance and mechanisms of sarcopenia are needed to inform a more personalized approach to mitigating the body composition changes associated with CTRT.

ESPEN guidelines on nutrition in cancer patients

Cancers are among the leading causes of morbidity and mortality worldwide, and the number of new cases is expected to rise significantly over the next decades. At the same time, all types of cancer treatment, such as surgery, radiation therapy, and pharmacological therapies are improving in sophistication, precision and in the power to target specific characteristics of individual cancers. Thus, while many cancers may still not be cured they may be converted to chronic diseases. All of these treatments, however, are impeded or precluded by the frequent development of malnutrition and metabolic derangements in cancer patients, induced by the tumor or by its treatment. These evidence-based guidelines were developed to translate current best evidence and expert opinion into recommendations for multi-disciplinary teams responsible for identification, prevention, and treatment of reversible elements of malnutrition in adult cancer patients. The guidelines were commissioned and financially supported by ESPEN and by the European Partnership for Action Against Cancer (EPAAC), an EU level initiative. Members of the guideline group were selected by ESPEN to include a range of professions and fields of expertise. We searched for meta-analyses, systematic reviews and comparative studies based on clinical questions according to the PICO format. The evidence was evaluated and merged to develop clinical recommendations using the GRADE method. Due to the deficits in the available evidence, relevant still open questions were listed and should be addressed by future studies. Malnutrition and a loss of muscle mass are frequent in cancer patients and have a negative effect on clinical outcome. They may be driven by inadequate food intake, decreased physical activity and catabolic metabolic derangements. To screen for, prevent, assess in detail, monitor and treat malnutrition standard operating procedures, responsibilities and a quality control process should be established at each institution involved in treating cancer patients. All cancer patients should be screened regularly for the risk or the presence of malnutrition. In all patients - with the exception of end of life care - energy and substrate requirements should be met by offering in a step-wise manner nutritional interventions from counseling to parenteral nutrition. However, benefits and risks of nutritional interventions have to be balanced with special consideration in patients with advanced disease. Nutritional care should always be accompanied by exercise training. To counter malnutrition in patients with advanced cancer there are few pharmacological agents and pharmaconutrients with only limited effects. Cancer survivors should engage in regular physical activity and adopt a prudent diet.
