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

Impact of low skeletal muscle mass in oropharyngeal cancer patients treated with radical chemo-radiotherapy: A mono-institutional experience

AIMS

Low skeletal muscle mass index (SMI) has recently emerged as an independent prognostic factor in oncological patients and it is linked with poor survival and higher treatment toxicity. The present study aims to determine the possible impact of low SMI on survival and acute toxicity in oropharyngeal patients.

METHODS

Seventy-six patients with locally advanced oropharyngeal squamous cell carcinoma (stage III-IVC) were treated in our institution with Helical TomoTherapy® (HT - Accuray, Maddison, WI, USA) between 2005 and 2021. All patients received concomitant platinum-based chemotherapy (CT) (at least 200 mg/m2). The SMI was determined using the calculation of cross-sectional area at C3. Twenty patients (26%) presented pre-treatment low SMI, according to Chargi definitions.

RESULTS

All patients concluded the treatment. Thirteen patients with low SMI (65%) and 22 patients with normal SMI (39%) presented acute toxicity greater than or equal to grade 3, but this difference was not statistically significant (p-value = 0.25). Overall survival was analyzed in 65 patients, excluding those who finished CT-RT less than six months before the analysis. Overall survival was significantly lower in low SMI versus normal SMI patients (p-value = 0.035). Same difference was observed in N0-N2a patients, suggesting an important role of SMI also in lower nodal burden and putatively better prognosis.

CONCLUSIONS

Although the results are limited to a small population, our case series has the advantage to be very homogeneous in patients and treatment characteristics. In our setting, SMI demonstrated a crucial impact on overall survival. Further investigation with larger samples is necessary to confirm our results to improve patient outcomes.

Body composition and dietary intake in patients with head and neck cancer during radiotherapy: a longitudinal study

OBJECTIVES

To investigate the body composition and dietary intake in the patients with head and neck cancer (HNC) during radiotherapy (RT), and explore the relationship between them.

METHODS

This was a prospective, longitudinal observational study. Adult patients with HNC undergoing RT between March 2017 and August 2018 were recruited. Patients' body compositions were evaluated by bioelectrical impedance analysis, and dietary intake was recorded by 24-hour dietary recall at three time points, including baseline (T1), mid-treatment (T2) and post-treatment (T3). Patients were divided into low, middle and high energy intake groups based on the average daily energy intake (DEI). Changes in body weight (BW), fat mass (FM), fat-free mass (FFM) and skeletal muscle mass (SMM) among these three groups were compared.

RESULTS

From T1 to T3, the median loss of patients' BW, FM, FFM and SMM was 4.60, 1.90, 2.60 and 1.50 kg, respectively. The loss of BW was more dramatic from T2 to T3 than that from T1 to T2. BW loss was mainly contributed by SMM loss from T1 to T2 and by FM loss from T2 to T3. Meanwhile, patients' dietary intake reduced during treatment. High DEI group had a significantly attenuated loss of patients' BW, FFM, SMM and FM compared with the low DEI group.

CONCLUSION

Patients' BW, FM, FFM and SMM all significantly reduced, especially from T2 to T3, with decreased DEI during RT, which stresses the importance of nutrition intervention during the whole course of RT.

Quality of weight loss during chemoradioherapy in patients with nasopharyngeal cancers

PURPOSE

Radiation therapy with chemotherapy (CCR) is currently the gold standard treatment for nasopharyngeal carcinoma (NPC). Anatomical changes are mainly due to weight loss. Our prospective study aimed to evaluate the nutritional status and the quality of weight loss in our patients to adapt the subsequent nutritional management of patients during treatment for NPC.

PATIENTS AND METHODS

A prospective, single-center study of 27 patients with non-metastatic NPC treated in our oncology radiotherapy department between August 2020 and March 2021. Data from interrogation, physical examination, and bioelectrical impedancemetry (weight [W], body mass index [BMI], fat index [GI], fat mass [FM], and fat-free mass (FFM]) were collected at the beginning, the mid, and the end of treatment.

RESULTS

Weight loss from mid to end of treatment (median=-4kg [-9.4; -0.9]) was greater than that from baseline to mid-treatment (median=-2.9kg [-8.8; 1.8]) (P=0.016). Weight loss during the entire treatment was -6.2kg [-15.6; -2.5] (8.4%). The losses of FM were identical between the beginning-mid treatment and the mid-end treatment; they were respectively -1.4kg [-8.5; 4.2] and -1.4kg [-8.2; 7.8] (P=0.4). FFM losses between the mid- and the end of treatment (-2.5kg [-27.8; 0.5]) were greater than those between baseline and mid-treatment (-1.1kg [-7.1; 4.7]) (P=0.014). Median FFM loss during treatment was -3.6kg [-28.1; 2.6]).

CONCLUSION

The results of our study show that weight loss during CCR for NPC is complex and is not just about loss but about a disruption of body composition. Regular follow-ups by nutritionists are required to prevent denutrition during treatment.

The impact of sarcopenia on survival and treatment tolerance in patients with head and neck cancer treated with chemoradiotherapy

BACKGROUND

Sarcopenia appears to be a negative prognostic factor for poor survival outcomes and worse treatment tolerance in patients with head-and-neck squamous cell carcinoma (HNSCC). We evaluated sarcopenia's impact on overall survival (OS), disease-free survival (DFS) and chemo-radiation tolerance in patients with head-and-neck cancer (HNC) treated with chemoradiotherapy (CRT) from a monocentric observational study.

METHODS

We identified patients with HNC treated by CRT between 2009 and 2018 with pretreatment imaging using positron emission tomography-computed tomography scans (PET/CT). Sarcopenia was measured using the pretreatment PET/CT at the L3 vertebral body using previously published methods. Clinical variables were retrospectively retrieved.

RESULTS

Of 216 patients identified, 54 patients (25.47%) met the criteria for sarcopenia. These patients had a lower mean body mass index before treatment (21.92 vs. 25.65 cm/m² , p < 0.001) and were more likely to have a history of smoking (88.89% vs. 71.52%, p = 0.01), alcohol use (55.56% vs. 38.61%, p = 0.03) and positive human papilloma virus status (67.74% vs. 41.75%, p = 0.011). At 3 years of follow-up, OS and DFS were 75% and 70% versus 82% and 85% for sarcopenic and non-sarcopenic patients, respectively (p = 0.1 and p = 0.00015). On multivariate analysis, sarcopenia appeared as a pejorative factor on DFS (hazard ratio 2.174, p = 0.0001) in the overall cohort. Sarcopenic patients did not require more chemotherapy and radiation-treatment interruptions and did not suffer from more chemo-induced and radiation-induced grade 3-4 toxicities than their non-sarcopenic counterparts.

CONCLUSION

Sarcopenia in HNSCC patients is an independent adverse prognostic factor for DFS after definitive chemoradiotherapy.

Prognostic Impact of Sarcopenia's Occurrence during Radiotherapy in Oropharyngeal Cancer Patients

The current study aims to profile sarcopenic condition (both at baseline and developed during treatment) in oropharyngeal carcinoma (OPC) patients treated with curative radiotherapy (RT) +/- chemotherapy and to evaluate its impact on oncological outcomes and toxicity. A total of 116 patients were included in this retrospective single-center study. Sarcopenia assessment at baseline and at 50 Gy re-evaluation CT was obtained from two different methodologies: (i) the L3-skeletal muscle index (SMI) derived from the contouring of the cross-sectional area (CSA) of the masticatory muscles (CSA-MM); and (ii) the paravertebral and sternocleidomastoid muscles at the level of the third cervical vertebra (CSA-C3). Based on L3-SMI from CSA-MM, developing sarcopenic condition during RT (on-RT sarcopenia) was associated with worse progression-free survival (PFS) (p = 0.03) on multivariable analysis and a trend of correlation with overall survival (OS) was also evident (p = 0.05). According to L3-SMI derived from CSA-C3, on-RT sarcopenia was associated with worse PFS (p = 0.0096) and OS (p = 0.013) on univariate analysis; these associations were not confirmed on multivariable analysis. A significant association was reported between becoming on-RT sarcopenia and low baseline haemoglobin (p = 0.03) and the activation of nutritional counselling (p = 0.02). No significant associations were found between sarcopenia and worse RT toxicity. Our data suggest that the implementation of prompt nutritional support to prevent the onset of sarcopenia during RT could improve oncological outcomes in OPC setting.

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.

Changes in Body Mass Index Are Associated with Squamous Cell Carcinomas of Oral Cavity, Oropharynx and Larynx: A Case-Control Study in Brazil

Head and neck cancer (HNC) significantly impacts nutritional status because the tumor limits swallowing function. In this sense, it is important to monitor the nutritional status throughout the life of any individual. A multicenter case-control study was carried out to analyze the BMI at 30 years of age, two years before diagnosis and at the time of diagnosis of individuals with oral cavity, oropharynx, and larynx cancers. It was observed that a 5% reduction in BMI during the two years before enrollment was associated with an increased risk of the oral cavity (OR = 3.73), oropharyngeal OR = 5.25), and laryngeal (OR = 5.22). Reduced BMI of more than 5% over two years before diagnosis was associated with HNC. Weight loss remained significant at diagnosis, but it is not possible to exclude reverse causality since most cases are at an advanced stage. BMI monitoring of individuals at potential risk for HNC can promote early diagnosis and nutritional interventions for HNC.

The relationship of serum gastrin-17 and oral mucositis in head and neck carcinoma patients receiving radiotherapy

OBJECTIVE

The aim of this study was to analyze the relationship of serum gastrin-17 (G-17) and oral mucositis in head and neck carcinoma (HNC) patients receiving radiotherapy.

METHODS

Serum G-17 were detected in patients before and after radiotherapy. Patients were divided into high G-17 group (baseline serum G-17 ≥ 5pmol/L) and low G-17 group (baseline serum G-17 < 5pmol/L). The severity of oral mucositis was analyzed between the two groups. Other complications such as dysphagia, salivary gland, mandible, thyroid function, larynx, pain, and weight loss were also investigated.

RESULTS

Forty-two patients were analyzed in this study. The level of serum G-17 had a significant decrease after radiotherapy (7.29 ± 5.70pmol/L versus 4.93 ± 4.46pmol/L, P = 0.038). In low serum G-17 group, the incidences of grade 0, 1-2 and 3-4 of oral mucositis were 0%, 30.4%, and 69.6%, respectively. In high serum G-17 group, the incidences of grade 0, 1-2 and 3-4 of oral mucositis were 0%, 63.2%, and 36.8%, respectively. Pearson correlation analysis showed that serum G-17 was negatively correlated with oral mucositis (r=-0.595, P < 0.01). Weight loss of low G-17 group was more serious than that of high G-17 group.

CONCLUSION

Serum G-17 has a close relationship with oral mucositis. Baseline serum G-17 may be a potential predictor for the severity of oral mucositis in HNC patients receiving radiotherapy.

Impact of photobiomodulation for oral mucositis on body weight and BMI of patients with head and neck cancer

PURPOSE

To evaluate the impact of photobiomodulation for oral mucositis on body weight and body mass index (BMI) in head and neck cancer patients.

METHODS

Patients were separated into two groups: photobiomodulation (PBM) (n = 17) and SHAM (n = 19). Participants assigned to the PBM group received the photobiomodulation therapy on alternate days at 33 different sites of the oral mucosa (1 J for 10 s per application point) using a low-power aluminum gallium arsenide (AsGaAl) laser device with a maximum output power of 86.7 mW and a wavelength of 660 nm (red). The same protocol was performed in patients allocated in the SHAM group but with the device turned off. At the first and twenty-fourth radiotherapy sessions, participants from both groups underwent an intraoral examination to assess the presence or absence of mucositis using the WHO scale, and measurements of weight and height for BMI calculation were undertaken.

RESULTS

All patients had significant differences in weight and BMI throughout the study period. Patients in the PBM group lost less weight (p < 0.01) and had a reduced BMI loss (p < 0.01) in comparison to patients in the SHAM group. Although PBM did not prevent oral mucositis, it decreased its severity (p < 0.01).

CONCLUSION

Photobiomodulation for oral mucositis reduced weight loss and prevented a reduction in BMI in patients who underwent chemoradiotherapy for head and neck cancer. Retrospectively registered at https://data.mendeley.com//datasets/4kd7s49wk4/1 .

A Review of Web-Based Nutrition Information in Spanish for Cancer Patients and Survivors

Nutrition education resources are of interest for cancer patients and survivors throughout the cancer continuum. We examined the web-based nutrition information in Spanish for cancer patients and survivors provided by national cancer organizations (NCOs). The Guide to Internet Resources for Cancer and the membership list of the Union for International Cancer Control were searched to identify the NCOs. The International Patients Decisions Aid Standards (IPDAS) was used to describe the quality of the available information. We identified 20 NCOs that provided nutrition information aimed at a general audience on their websites. Web-based resources of nine NCOs were selected for presentation in this review. Website scores ranged between 20 and 24 in the IPDAS scale (maximum score = 31). The selected NCOs offered reliable and safe information. Healthy eating information for cancer patients and management of side-effects was provided by all websites. Information was more limited for cancer survivors. We recommend that NCOs increase the possibilities for personalized recommendations and interaction with the content by including instrumental tools on their websites.

Clinically significant changes in health-related quality of life in head and neck cancer patients following intensive nutritional care during radiotherapy

PURPOSE

This study aimed to explore whether adherence to intensive nutritional care during radiotherapy would avoid a meaningful worsening in quality of life in head and neck cancer patients; and whether adherence was associated with better nutritional outcomes.

METHODS

Observational prospective study that assessed head and neck cancer patients treated with radiotherapy at a large oncology hospital, between August 2018 and April 2019. The main outcome was minimal clinically important difference in quality of life, assessed with EORTC QLQ-C30 and EORTC QLQ H&N35, between baseline and 12 weeks. To illustrate clinically significant changes in quality of life over timeby adherence, a heat map analysis was performed. We also evaluated nutritional outcomes.

RESULTS

Eighty patients were included, half of them (53.8%) were considered adherent. There were no significant difference in quality of life between groups at baseline, with the exception of swallowing (p = 0.029) and coughing (p < 0.01). After treatment, the heat map demonstrated that adherent patients had nonsignificant clinical change in function scales, while non-adherent patients had a clinically significant worsening in physical, cognitive and social function. The prevalence of malnutrition increased significantly only in non-adherent patients (p < 0.01).

CONCLUSION

Adherence to intensive nutritional care may be able to avoid a meaningful worsening in quality of life and result in better nutritional outcomes in head and neck cancer patients. Our results may help to increase the awareness of the assessment of adherence and minimal clinically important difference in quality of life for research purposes and clinical practice.

Identifying Patient-Reported Outcome Measures (PROMs) for Routine Surveillance of Physical and Emotional Symptoms in Head and Neck Cancer Populations: A Systematic Review

The aims of this review were to identify symptoms experienced by head and neck cancer (HNC) patients and their prevalence, as well as to compare symptom coverage identified in HNC specific patient-reported outcome measures (PROMs). Searches of Ovid Medline, Embase, PsychInfo, and CINAHL were conducted to identify studies. The search revealed 4569 unique articles and identified 115 eligible studies. The prevalence of reported symptoms was highly variable among included studies. Variability in sample size, timing of the assessments, and the use of different measures was noted across studies. Content mapping of commonly used PROMs showed variability and poor capture of prevalent symptoms, even though validation studies confirmed satisfactory reliability and validity. This suggests limitations of some of the tools in providing an accurate and comprehensive picture of the patient's symptoms and problems.

Circulating fatty acids in patients with head and neck cancer after treatment: an explorative study with a one-year perspective

BACKGROUND

Unintended weight loss and nutritional problems are often seen in patients with head and neck cancer, but changes in lipid metabolism are poorly studied.

AIM/OBJECTIVES

The present study aimed to explore the longitudinal changes in circulating fatty acid (FA) composition in patients with head and neck cancer.

MATERIALS AND METHODS

This study included 27 patients with head and neck cancer. Treatment consisted of single modality or combined modality treatments. The patients were assessed by repeated blood sampling and body weight assessments before treatment started and on three occasions after the start of treatment. FA profiling included gas chromatography analysis of unsaturated FAs and saturated FAs in serum.

RESULTS

The values of three fatty acids - FA 14:0, FA 18:3n3, and FA 20:3n6 - changed in a specific pattern over the course of the study and the change in FA 14:0 correlated with weight changes.

CONCLUSIONS AND SIGNIFICANCE

This study showed altered profiles of both saturated and unsaturated FAs. An improved understanding of the metabolic pathways in patients with head and neck cancer supports the development of better nutritional surveillance and nutritional treatments.

Ibero-American Expert Consensus on Squamous Cell Carcinoma of the Head and Neck Treatment in Patients Unable to Receive Cisplatin: Recommendations for Clinical Practice

Cisplatin is the standard of treatment for squamous cell carcinoma of the head and neck (SCCHN) that has demonstrated efficacy, either in locally advanced disease when combined with radiotherapy at high doses, or in metastatic/recurrent disease when combined with other agents. However, the usual toxicities related to cisplatin, such as neurotoxicity, nephrotoxicity, ototoxicity, and hematologic toxicities, especially when high doses have been administered, have important implications in the patients' quality of life. The decision to administer cisplatin depends on several patient factors, such as age, performance status, weight loss, comorbidities, previous toxicities, chronic viral infection, or even the current SARS-CoV-2 pandemic. In order to establish recommendations for the management of patients with SCCHN, a group of experts in medical and radiation oncology from Spain and Latin-American discussed how to identify patients who are not candidates for cisplatin to offer them the most suitable therapeutic alternative.

Predictive Value of Skeletal Muscle Mass in Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma Patients Treated With Immune Checkpoint Inhibitors

Background

Reduced muscle mass has been associated with increased treatment complications in several tumor types. We evaluated the impact of skeletal muscle index (SMI) on prognosis and immune-related adverse events (IrAEs) in a cohort of recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) treated with immune checkpoints inhibitors (ICI).

Methods

A single-institutional, retrospective study was performed including 61 consecutive patients of R/M HNSCC diagnosed between July 2015 and December 2018. SMI was quantified using a CT scan at L3 to evaluate body composition. Median baseline SMI was used to dichotomize patients in low and high SMI. Kaplan-Meier estimations were used to detect overall survival (OS) and progression-free survival (PFS). Toxicity was recorded using Common Terminology Criteria for Adverse Event v4.3.

Results

Patients were 52 men (85.2%) with mean of age 57.7 years (SD 9.62), mainly oral cavity (n = 21; 34.4%). Low SMI was an independent factor for OS in the univariate (HR, 2.06; 95% CI, 1.14–3.73, p = 0.017) and multivariate Cox analyses (HR, 2.99; 95% CI, 1.29–6.94; p = 0.011). PFS was also reduced in patients with low SMI (PFS HR, 1.84; 95% CI, 1.08–3.12; p = 0.025). IrAEs occurred in 29 (47.5%) patients. There was no association between low SMI and IrAEs at any grade (OR, 0.56; 95% CI, 0.20–1.54; p = 0.261). However, grades 3 to 4 IrAEs were developed in seven patients of whom three had low SMI.

Conclusions

Low SMI before ICI treatment in R/M HNSCC patients had a negative impact on OS and PFS. Further prospective research is needed to confirm the role of body composition as a predictive biomarker in ICI treatment.

Protective Effect of Quercetin Nanoemulsion on 5-Fluorouracil-Induced Oral Mucositis in Mice

The target of this study was to evaluate the efficacy, histopathological, oxidative stress, and molecular effects of quercetin (QRC) in mice with oral mucositis induced by 5-fluorouracil (5-FU). Thirty-six albino male mice with oral mucositis induced by 5-FU as a chemotherapeutic agent were used in this study. The animals were randomly divided into 6 groups: control group, mucositis (MUC) group, pretreatment group, posttreatment group, and two last groups including nanoemulsion form of QRC with a dose of 5 mg/kg in both pretreatment and posttreatment. In the present evaluation, fewer oral lesions were observed in the QRC posttreatment groups compared to the pretreatment and nanoemulsion receiving groups. In the SOD assay, the most significant difference was observed in the posttreatment nanogroup (41.073 ± 1.24) and pretreatment nanogroup (43.453 ± 2.60) in comparison to the 5-FU group (30.897 ± 1.93). The results of CAT assay also showed a significant difference in nano-posttreatment (124.60 ± 10.85), posttreatment (135.4 ± 9.82), and nano-pretreatment groups (128.80 ± 7.20) compared to the 5-FU group (55.07 ± 8.91). The expression of inflammatory genes such as Hif-1α and NfκB in this group was lower than in the other groups, although this difference was not significant. It seems that the use of QRC can improve the treatment process of oral mucositis induced by 5-FU.

Evolution of Nutritional Status in Patients with Advanced Head and Neck Cancer Undergoing Surgical Treatment or Organ Preservation Protocol

We sought to evaluate the evolution of the nutritional status of patients with advanced cancer of the upper aerodigestive tract undergoing surgical treatment (SURG) or organ preservation protocol (OP). Evaluations were conducted at the beginning and end of treatment, including weight, body composition and Patient-Generated Subjective Global Assessment (PG-SGA). Each group was comprised of 29 patients. Initially, malnutrition rates were 65.5% and 51.7% in the SURG and OP groups, respectively. At the end, the values went to 55.1% in SURG and 79.3% in OP. In the OP, there was a reduction in weight (P = 0.001), fat mass (P = 0.006), fat free mass (P = 0.002), and muscle mass (P = 0.005) and an increase in scores of the PG-SGA (P = 0.008). The same was not observed in SURG, except for the weight decrease (P = 0.025). Malnutrition was prevalent in both treatment groups and patients in OP were at greater risk of nutritional decline.

Mapping Health-Related Quality of Life, Anxiety, and Depression in Patients with Head and Neck Cancer Diagnosed with Malnutrition Defined by GLIM

Patients with cancer deal with problems related to physical, psychological, social, and emotional functions. The aim was to investigate malnutrition defined by the Global Leadership Initiative on Malnutrition (GLIM) criteria in relation to health-related quality of life, anxiety, and depression in patients with head and neck cancer. This was a prospective observational research study with 273 patients followed at the start of treatment, seven weeks, and one year. Data collection included nutritional status and support, and the questionnaires: European Organization for Research and Treatment of Cancer Head and neck cancer module (EORTC QLQ-H&N35) and the Hospital Anxiety and Depression Scale (HADS). Malnutrition was defined using the GLIM criteria. The study showed that patients with malnutrition had significantly greater deterioration in their health-related quality of life at seven weeks. On a group level, health-related quality of life was most severe at this time point and some scores still implied problems at one year. Significantly, more patients reported anxiety at the start of treatment whereas significantly more patients reported depression at seven weeks. Over the trajectory of care, the need for support often varies. Psychosocial support is imperative and at the end of treatment extra focus should be put on nutritional interventions and managing treatment-related symptoms to improve nutritional status and health-related quality of life. In the long-term, head and neck cancer survivors need help to find strategies to cope with the remaining sequel.

The prevalence of sarcopenia and relationships between dietary intake and muscle mass in head and neck cancer patients undergoing radiotherapy: A longitudinal study

PURPOSE

Our study aims to investigate dietary intake characteristics and their association with skeletal muscle mass in head and neck cancer patients treated with radiotherapy.

METHODS

From March 2017 to August 2018, patients with head and neck cancer who received radiotherapy at our affiliated hospital were enrolled. Dietary intake was assessed through 24-hr dietary recall and skeletal muscle mass was evaluated by bioelectrical impedance analysis at three-time points. Appendicular skeletal muscle mass was adjusted for height squared defined sarcopenia and correlated with dietary intake by generalized estimating equations (GEE).

RESULTS

This study sample comprised 287 patients [median age: 54 years; 187 (65.2%) men]. Median dietary intake at post-treatment was 14.95 kcal/kg/day energy and 0.63 g/kg/day protein. Skeletal muscle mass decreased significantly in all patients. The prevalence of sarcopenia increased from 24.4% before treatment to 46.7% at the end of treatment. Exploratory univariate GEE analysis revealed that radiotherapy time-point, male-gender, age ≥60 and decreased dietary energy intake significantly impacted on muscle loss represented by the appendicular skeletal muscle index. After controlling covariates, dietary energy intake was only positively associated with muscle loss in women (P = 0.013, 95% CI = 0.003-0.027) but not in men (P = 0.788, 95% CI = -0.007-0.009).

CONCLUSION

While the loss in skeletal muscle is more prevalent in men receiving radiotherapy, the effects of dietary energy intake were only associated with women. A prospective randomized clinical trial is required to identify the appropriate amount of dietary energy supplement by gender in cancer patients treated with radiotherapy.

Progressive muscle loss is an independent predictor for survival in locally advanced oral cavity cancer: A longitudinal study

BACKGROUND AND PURPOSE

To investigate the association between progressive muscle loss and survival outcomes of patients with advanced-stage oral squamous cell carcinoma (OSCC) undergoing surgery and adjuvant (chemo)radiotherapy.

METHODS

We analyzed the computed tomography (CT) scans of 155 patients with stage III-IVB OSCC at baseline, at simulation CT for radiotherapy, and at 3- and 9-months post-treatment. Skeletal muscle index (SMI) was measured using CT at the C3 vertebral level. The predictors of overall survival (OS) and recurrence-free survival (RFS) were evaluated using Cox regression models.

RESULTS

The median follow-up period was 75.0 months. Fifty-one patients (32.9%) developed recurrence, with the median time from the fourth CT to recurrence being 9.1 months. The SMI progressively decreased from baseline to simulation CT by 1.1% (p = 0.006), to 3 months post-treatment by 5.1% (p < 0.001), and to 9 months post-treatment by 15.6% (p < 0.001) in patients developing recurrence. Patients without recurrence lost SMI at the simulation CT by 0.7% (p = 0.001) and at 3 months post-treatment by 2.1% (p < 0.001); their SMI returned to the baseline level at 9 months post-treatment. SMI changes were weakly correlated with changes in body mass index (BMI) (Spearman ρ, 0.13; p = 0.11). In multivariate analysis, SMI changes (per 5% decrease) were independently associated with significantly worse OS (hazard ratio: 1.88, 95% confidence interval: 1.58-2.23; p < 0.001) and RFS (hazard ratio: 1.89, 95% confidence interval: 1.61-2.20; p < 0.001).

CONCLUSION

Progressive muscle loss was independently associated with worse survival outcomes in patients with stage III-IVB OSCC. Muscle loss might not be detected by changes in BMI.

Nutritional Deficiencies in Radiotherapy-Treated Head and Neck Cancer Patients

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

The impact of skeletal muscle depletion on older adult patients with head and neck cancer undergoing primary surgery

INTRODUCTION

Sarcopenia may result in negative outcomes in patients with cancer, but its impact on surgical and oncological outcomes in older adult patients with head and neck squamous cell carcinoma (HNSCC) has not been systematically studied. This study evaluated the clinical impact of sarcopenia on postsurgical and oncological outcomes in older adult patients with HNSCC.

METHODS

This is a prospective study of 190 consecutive HNSCC patients aged ≥65 years who underwent curative surgery at a tertiary referral hospital. Sarcopenia was determined from measurement of the cross-sectional area of skeletal muscles at the level of the third lumbar vertebra on pretreatment images of whole body ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography. Primary outcomes were early complications and overall survival. Factors of early complications and readmission were identified using binary logistic regression analyses, and factors of overall survival and disease-free survival were identified using univariate and multivariate Cox proportional hazards regression analyses.

RESULTS

Pretreatment sarcopenia were found in 64 (33.7%) patients. In multivariate analysis, sarcopenia and N classification were significantly associated with early complications, while sarcopenia and T classification were associated with readmission. Independent factors of overall survival outcomes were age, sarcopenia, and extranodal extension (all P < .005). Sarcopenia was also an independent factor predictive of disease-free survival outcome (P < .001). Sarcopenia was associated with a 3.2-fold increase in the early complication rate and 4.5-fold increase in mortality in older adult surgical patients with HNSCC.

CONCLUSION

Sarcopenia may predict early complications and survival after curative surgery in older adult patients with HNSCC.

Adherence to intensive nutrition care in head and neck cancer patients undergoing radiotherapy

PURPOSE

The aim of this study was to determine the prevalence and effect of adherence to intensive nutritional care on nutritional outcomes and survival in head and neck cancer patients undergoing radiotherapy.

METHODS

Three-hundred and seventeen head and neck cancer patients referred to intensive nutrition support during radiotherapy were retrospectively analyzed. Patients who missed less than 25% of their appointments with the dietitian were considered adherent. Primary outcome was percentage weight loss during treatment. Secondary outcomes were overall survival and patients' capacity to accomplish their caloric and protein recommendations. Logistic regression was used to examine predictors of weight loss and Kaplan-Meier to estimate survival.

RESULTS

Less than half of the patients (n = 145, 45.7%) were adherent. Statistically significant less weight loss in the adherent group (42.8% vs 55.8%; p = 0.02) was found, despite no difference in energy or protein intake. Logistic regression models after adjusting for other variables demonstrated that adherence resulted in 43% protection from significant weight loss (odds ratio 0.57, 95% CI 0.34-0.97). Overall survival was not different between groups.

CONCLUSION

Findings demonstrated that patients who were adherent to weekly contacts with the dietitian had less weight loss, but not better survival or nutritional intake. Additional investigation of factors that may act as barriers or enablers for adherence could help improve the outcomes in this population.

Nutritional outcomes in head and neck cancer patients: is intensive nutritional care worth it?

OBJECTIVE

This study aimed to compare nutritional outcomes before and after implementation of weekly dietetic counseling (intensive nutritional care) in head and neck cancers patients.

METHODS

A retrospective study with all head and neck patients, who received radiotherapy between January 2010 and December 2017 were performed. The main outcome was significant weight loss. Compliance to caloric and protein recommendations were also evaluated.

RESULTS

In all, 472 patients were included. Weight loss was not different between before and after implementation (-6.7%; IQ -10.5/-1.9 vs -5.0%; IQ -9.8/-0.7;p=0.06).There were no significant difference in terms of meeting the recommended intake. Higher baseline body mass index and oral nutritional support predicted significant weight loss.

CONCLUSION

Implementation of intensive nutritional care did not have an impact on weight loss and energy and protein intake in head and neck cancer patients. Further research would be of value to determine the appropriate service-delivery model to achieve optimal patient outcomes.

Nutritional Status and Its Association With Radiation-Induced Oral Mucositis in Patients With Nasopharyngeal Carcinoma During Radiotherapy: A Prospective Study

Background and Aims

Malnutrition is a concern in patients with nasopharyngeal carcinoma (NPC) during chemoradiotherapy (CRT)/radiotherapy (RT), which is considered to be related with radiation–induced oral mucositis (ROM). The study aimed to evaluate the nutritional status of NPC patients during RT and investigate its association with ROM.

Methods

A prospective study was conducted in NPC patients. Patients were divided into three subgroups (mild, moderate, and severe groups) based on the duration of severe ROM (≥ grade 3). Body weight, body mass index (BMI), albumin, prealbumin, NRS2002, and ROM grade were assessed on a weekly basis before and during CRT/RT. The statistical analysis was performed in the overall group and between three subgroups.

Results

A total of 176 patients were included. In the overall group, body weight and BMI kept decreasing since week 1 of RT, and NRS2002 score and ROM grade increased (p < 0.001). NRS2002 score and prealbumin levels were significantly different between each subgroup (p ≤ 0.046). Significant differences were observed in the proportion of patients receiving enteral nutrition, duration of parenteral nutrition, and total calories provided by nutritional support among three subgroups (p = 0.045–0.001).

Conclusions

Malnutrition occurred early in NPC patients and worsened continuously during RT. ROM was strongly associated with nutritional status. Nutritional support should be provided at the start of RT, especially in patients at high-risk of severe ROM.

A Systematic Review: Dietary Habits of Women with Gynecological Cancer before, during and after Treatment

INTRODUCTION

Cancer treatment can affect eating habits and some patients treated with pelvic radiotherapy develop chronic changes in their bowel function which may impact on dietary intake. This systematic review summarizes current research on dietary habits before, during and after treatment in women with a gynecological malignancy.

METHODS

MEDLINE, EMBASE, CINAHL and PubMed databases were searched until August 1, 2019, with no language restrictions. PRISMA guidelines for systematic reviews were used to ensure transparent and complete reporting (Liberati et al., 2009). Quantitative studies exploring dietary habits before, during or after treatment for gynecological cancer were included.

RESULTS

Three prospective cohort studies (98 participants) were included. All patients were treated with radiotherapy; some also had surgery and chemotherapy. Studies reported similar changes in weight, BMI and energy intake and found that patients lose weight during treatment, but this was not long-lasting. Long-term results suggest that fat and protein intake increase significantly (p < 0.01). There was no correlation of symptoms with any nutritional parameters.

CONCLUSION

Evidence from three studies suggests further studies including long-term assessment of dietary intake in women treated for a gynecological malignancy are warranted to explore the impact of cancer treatments on dietary intake and its relation to developing long-term gastrointestinal toxicity.

Early versus conventional nutritional intervention in head and neck cancer patients before radiotherapy: benefits of a fast-track circuit

BACKGROUND/OBJECTIVES

Radiotherapy (RT) is a component of therapy for head and neck cancer (HNC) with a negative nutritional impact. Our aim was to compare an early versus a conventional nutritional intervention.

SUBJECTS AND METHODS

Retrospective study of HNC patients undergoing RT. Evolution before and after the establishment of a fast-track circuit was evaluated. A conventional group (CG) made up of patients submitted to the nutrition unit during RT after nutritional deterioration, was compared to an early group (EG) represented by patients included in a fast-track circuit, starting nutritional follow-up before the beginning of RT. Only patients with preserved oral intake were involved. Demographic, nutritional and clinical variables were analyzed. Data of hospitalizations and deaths were collected up to three months after RT.

RESULTS

135 subjects constituted the EG and 39 the CG. At baseline, the prevalence of malnutrition was lower in the EG (31.9% vs 69.5%, p = 0.0001), as was the need for nutritional supplements (40% vs 79.5%, p = 0.0001) or nasogastric tube (0% vs 12.8%, p = 0.0001) in comparison to the CG. Three months after RT, there were less patients with oral nutritional support in the EG (79.1% vs 96.9%, p = 0.018), and the number of emergency visits (0.75 vs 1.1 episodes per patient, p = 0.021) and hospitalizations was also lower in this group (29% vs 59%, p = 0.044).

CONCLUSIONS

The fast-track approach made early intervention possible. Therefore, patients maintained a better nutritional status, needed less nutritional support and their evolution improved, with a significant decrease in hospitalizations.

A prospective randomized controlled trial on the value of prophylactic oral nutritional supplementation in locally advanced nasopharyngeal carcinoma patients receiving chemo-radiotherapy

OBJECTIVES

We investigated the effect of prophylactic oral nutrition supplements (ONS) in locally advanced nasopharyngeal carcinoma patients receiving neoadjuvant chemotherapy and concurrent chemoradiotherapy (CCRT).

METHODS

Eligible patients were randomly assigned to an intervention or control group. Patients in the intervention group were supported with prophylactic ONS from the beginning of CCRT. The control group received nutritional support only when necessary. Bodyweight, hematological indexes, nutritional status, and quality of life were measured at baseline and before, during, and after RT.

RESULTS

We evaluated 114 patients from October 2016 to May 2018. More than half of patients experienced significant weight loss during CCRT, which continued for three months after radiotherapy (RT). Compared to baseline, the rate of weight loss ≥ 5% before, during, at the end of RT, and one and three months after RT were 3.5%, 28.9%, 51.8%, 61.4%, and 61.4%, respectively. Nutritional status and global health status scores progressively decreased during treatment. The rate of RT interruption was higher in the control group than in the intervention group (7.14% vs. 0%, χ² = 4.29, P = 0.04). More patients experienced concurrent chemotherapy interruption in the control group than in the intervention group (28.57% vs 10.34%, χ² = 6.08, P = 0.01). There were no significant differences in weight loss, nutritional status, quality of life, and global health status between two groups.

CONCLUSIONS

Malnutrition and weight loss progressively increased during treatment. Prophylactic ONS can improve tolerance to CCRT, but it offers no advantage on short-term weight loss or nutritional assessment scores.

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.

GASTROINTESTINAL CHANGES DURING NUTRITIONAL FOLLOW-UP OF CANCER PATIENTS UNDERGOING OUTPATIENT CHEMOTHERAPY

BACKGROUND

Cancer patients may have gastrointestinal changes that influence nutritional status.

OBJECTIVE

To investigate the occurrence of gastrointestinal changes resulting from outpatient chemotherapy treatment in cancer patients.

METHODS

In a retrospective longitudinal study, the nutritional status and chemotherapy gastrointestinal changes (nausea, vomit, diarrhea, constipation, mucositis, dysphagia, xerostomia, inappetence, dysgeusia and heartburn) in cancer patients (n=187) were investigated in an outpatient follow-up. For the study of the parameters over time, the generalized estimating equation (GEE) method was used. Kruskal-Wallis, Mann-Whitney tests and Spearman coefficient, at a significance level of 5% were also used.

RESULTS

The majority of the patients were female (63.64%) and the mean age was 57.5±12.1 years. The most frequent symptoms were nausea (18.54%); inappetence (18.31%); intestinal constipation (11.58%); diarrhea (7.98%); xerostomia (7.59%) and vomiting (7.43%). The nutritional status did not exhibit any relevant changes (P=0.7594). However, a higher prevalence of eutrophy was observed, followed by overweight; vomiting exhibited a significant difference (P=0.0211). The nausea symptom exhibited a significant difference with a higher prevalence of colorectal neoplasia when compared to breast neoplasia (P=0.0062); as well as vomiting in lung and colorectal neoplasias (P=0.0022), and dysphagia, in head and neck neoplasia, when compared to other neoplasms (P<0.001). There was a statistically significant difference between the number of medical appointments and gender (P=0.0102) and between dysphagia and gender (P<0.0001).

CONCLUSION

The study findings enhance the need for signs and symptoms follow up, as well as nutritional status follow up of patients undergoing outpatient chemotherapy.

Onodera's prognostic nutritional index correlates with tumor immune environment and survival in patients with oral squamous cell carcinoma undergoing chemoradiotherapy

Pretreatment nutritional and immunological status is useful for predicting survival outcomes for various types of malignant tumors. Our objective was to determine the impact of the pretreatment Onodera's prognostic nutritional index (OPNI) on outcomes of patients who underwent definitive chemoradiotherapy for advanced oral squamous cell carcinoma (OSCC). We reviewed 47 patients treated for OSCC with definitive chemoradiotherapy (CRT) at our institution between January 2004 and December 2011. We determined the OPNI according to the following formula: 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (per μL). We determined the optimum OPNI cut-off through a receiver operating characteristic analysis. We analyzed the associations between OPNI status and various clinicopathological features and evaluated the effects of OPNI on the prognosis. We examined the relationships between OPNI and systemic inflammatory response parameters and analyzed intratumoral CD8+ T cells and their correlation with OPNI. The optimum OPNI cut-off was 42.7. A Kaplan–Meier curve analysis revealed that low OPNI was significantly associated with poor overall survival and cause-specific survival. The multivariate analysis revealed that low OPNI was independently correlated with poor 5 year overall survival and cause-specific survival. OPNI was significantly correlated with systemic inflammatory response parameters. Intratumoral CD8+ T cell counts in primary tumors were significantly lower for low OPNI than for high OPNI. The present data demonstrate that pretreatment OPNI is a valuable independent prognostic indicator of overall and cause-specific survival in advanced OSCC following definitive CRT. OPNI might reflect the tumor immune microenvironment characterization in OSCC.

•

The optimum Onodera's prognostic nutritional index (OPNI) cut-off was 42.7 in OSCC patients who underwent definitive chemoradiotherapy

•

Low OPNI was significantly associated with poor overall survival and cause-specific survival

•

OPNI was significantly correlated with systemic inflammatory response parameters

•

High-OPNI group showed significantly higher intratumoral CD8+ T cell counts in primary tumors

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.

The Impact of Protein Supplementation Targeted at Improving Muscle Mass on Strength in Cancer Patients: A Scoping Review

Deterioration of muscle strength during cancer results in functional limitation, poor quality of life and reduced survival. The indirect effects on muscle strength of nutritional interventions based on protein and amino acid derivatives targeted at improving muscle mass are poorly documented. A scoping review was performed to examine the available evidence on the effects of proteins, amino acids and their derivatives on muscle strength in adult cancer patients. Pubmed and Scopus databases were searched to identify research articles published in the last 10 years. Fourteen studies met the inclusion criteria, showing that changes in muscle strength following protein or amino acid supplementation are generally concordant with those in muscle mass in cancer patients. Administration of both energy and proteins in the presence of reduced oral intakes results in more robust effects on both muscle strength and mass. It is not clear whether this is due to the correction of the energy deficit or to an interaction between proteins and other macronutrients. The optimal mixture, type, and dose of amino acid/protein supplementation alone or in combination with other anabolic strategies should be determined to provide the best nutritional approach in cancer.

Body composition changes in patients with head and neck cancer under active treatment: a scoping review

BACKGROUND

Head and neck cancer patients have the second highest malnutrition prevalence, when compared with other oncological patients. They experience significant weight loss before diagnosis, during and after treatment, and even during the first year of follow-up. However, the prognostic value of weight loss depends on body mass index, and this may be associated with low skeletal muscle mass, masking its loss. Thus, weight loss itself poorly predicts outcome in head and neck cancer patients when compared with depleted skeletal muscle mass, illustrating the inadequacy of body mass index as an accurate method to reflect nutritional status. A synthesis is needed of the body composition changes occurring in head and neck cancer patients during treatment, as well as of the methods to assess it.

OBJECTIVE

The aim of this scoping review is to examine and map the body composition changes in head and neck cancer patients under oncological treatment with curative intent. A further objective is to determine which methods are used to assess body composition in these patients.

INCLUSION CRITERIA

Types of participants: The current review considered head and neck cancer patients, aged 18 years or older.

CONCEPT

This scoping review considered all studies that focused on the body composition changes.

CONTEXT

This scoping review considered the studies that evaluated the body composition changes in the context of treatment with curative intent. Surgical treatment approach was excluded to avoid excess heterogeneity in the data. Types of sources: This scoping review considered only published studies, with abstract available.

SEARCH STRATEGY

A three-step search strategy was undertaken. This review was limited to studies published in English, Spanish, and Portuguese during 2000-2019.

DATA EXTRACTION

The data extracted included author(s)/year of publication, aims and purpose of the study, sample size, study design, type of treatment, measurement points and component(s) of body composition evaluated, body composition assessment methods, and main results/findings.

PRESENTATION OF RESULTS

Head and neck cancer patients suffer from serious loss of lean body mass, skeletal muscle, or free fat mass, after treatment compared with baseline. Further, nutritional deterioration is evident and occurs up to 8-12 months after treatment. Bioelectrical impedance analysis is one of the body composition assessment tools that has the great advantage for being available on a regular basis for assessment of body composition in head and neck cancer patients. However, it cannot be recommended for clinical decision making until further validation.

CONCLUSION

Head and neck cancer patients experience a significant depletion of lean body mass, fat-free mass, and skeletal muscle, accompanied by body fat mass, while undergoing (chemo)radiotherapy. This can be demonstrated either by triceps skinfold thickness, bioelectrical impedance analysis, dual-energy x-ray absorptiometry, or computed tomography. This loss has a remarkable impact on their survival, on their quality of life, and on the risk for post-operative complications and may result in a reduced response to cancer treatment. Thus, body composition assessment should become an integral component of the care of head and neck cancer patients, beyond weight and body mass index, and should be carried out at different times throughout treatment.

Cannabidiol on 5-FU-induced oral mucositis in mice

PURPOSE

The aim of this study was to evaluate the clinical, histological, hematological, and oxidative stress effects of cannabidiol (CBD) in mice with induced oral mucositis.

METHODS

We used 90 mice of the CF-1 strain in which oral mucositis was induced using a protocol with 5-fluorouracil (5-FU) chemotherapy. The animals were divided randomly into 10 study groups. Three groups were treated with different doses of CBD (3, 10, and 30 mg/kg), while 2 were control groups (positive control: 5-FU + mechanical trauma + placebo; and negative control: mechanical trauma + placebo), and 2 experimental times were studied (4 and 7 days). All treatments were by intraperitoneal administration.

RESULTS

In the clinical evaluation, the groups treated with CBD showed less severity of oral lesions compared with the positive control at both experimental times. The intensity of the inflammatory response was also lower in the groups treated with this drug, but there was no statistically significant difference when compared with the positive control. With regard to erythrocyte, leukocyte, and platelet counts and anti-oxidant enzyme activity, the groups treated with CBD showed better results, but only some of these variables showed statistically significant differences.

CONCLUSIONS

CBD seems to exert an anti-inflammatory and anti-oxidant activity favoring a faster resolution of oral mucositis in this animal model.

Swallowing functional outcomes and nutritional status in head and neck cancer radiotherapy: longitudinal study

Objective

To explore the relationships between swallowing functional outcomes and nutritional status in patients with head and neck cancer undergoing radiotherapy (RT).

Methods

This longitudinal study included 122 patients. Data were collected at three time points: baseline (T1), the third week of RT (T2) and the completion of RT (T3). The Common Terminology Criteria for Adverse Events was used to assess the symptom of dysphagia and other toxicities; the MD Anderson Dysphagia Inventory (MDADI) was used to assess the patient-perceived swallowing functional outcomes; the nutritional status was evaluated by the weight ratio and the Patient-Generated Subjective Global Assessment (PG-SGA). The generalised estimating equation (GEE) was used to measure the correlation of MDADI with the weight ratio or PG-SGA and also to analyse the influential factors of swallowing functional outcomes.

Results

The participants’ acute dysphagia rates were 5.7% at T1, 69.7% at T2 and 77.9% at T3. The swallowing functional outcomes worsen over RT (p<0.001) and were associated with weight ratio (β=0.032, p=0.008) and PG-SGA (β=−0.115, p<0.001). GEE models showed that patients with cancer of the pharynx region, advanced stage, chemoradiotherapy and high RT dose perceived worse swallowing functional outcomes. Oral mucositis, pharynx mucositis and salivary gland inflammation were positively correlated with swallowing functional outcomes, and the pharynx mucositis presented the highest absolute value of β.

Conclusion

The swallowing functional outcomes were negatively correlated with nutritional status. Healthcare professionals should identify early on the population at higher risk and focus on multiple toxicities, especially the management of pharynx mucositis, to improve nutritional status.

The Multidisciplinary Team (MDT) Approach and Quality of Care

The core function of a multidisciplinary team (MDT) is to bring together a group of healthcare professionals from different fields in order to determine patients' treatment plan. Most of head and neck cancer (HNC) units are currently led by MDTs that at least include ENT and maxillofacial surgeons, radiation and medical oncologists. HNC often compromise relevant structures of the upper aerodigestive tract involving functions such as speech, swallowing and breathing, among others. The impairment of these functions can significantly impact patients' quality of life and psychosocial status, and highlights the crucial role of specialized nurses, dietitians, psycho-oncologists, social workers, and onco-geriatricians, among others. Hence, these professionals should be integrated in HNC MDTs. In addition, involving translational research teams should also be considered, as it will help reducing the existing gap between basic research and the daily clinical practice. The aim of this comprehensive review is to assess the role of the different supportive disciplines integrated in an MDT and how they help providing a better care to HNC patients during diagnosis, treatment and follow up.

Disease-induced and treatment-induced alterations in body composition in locally advanced head and neck squamous cell carcinoma

BACKGROUND

Chemoradiation or bioradiation treatment (CRT/BRT) of locally advanced head and neck squamous cell carcinoma (LAHNSCC) comes with high toxicity rates, often leading to temporary tube feeding (TF) dependency. Cachexia is a common problem in LAHNSCC. Yet changes in body composition and muscle weakness during CRT/BRT are underexplored. Strong evidence on the effect of TF on body composition during treatment is lacking. The aim of this cohort study was to assess (i) the relationship of fat-free mass index (FFMI) and handgrip strength (HGS) with CRT/BRT toxicity and outcome, (ii) body composition in patients treated with chemoradiation (cisplatin) vs. bioradiation (cetuximab), and (iii) the effect of the current TF regime on body composition and muscle strength.

METHODS

Locally advanced head and neck squamous cell carcinoma patients treated with CRT/BRT between January 2013 and December 2016 were included (n = 137). Baseline measurements of body composition (bioelectrical impedance analysis) and HGS were performed. Toxicity grades (Common Terminology Criteria for Adverse Events) were scored. In a subset of 69 patients, weight loss, body composition, and HGS were additionally assessed during and after CRT/BRT. TF was initiated according to the Dutch guidelines for malnutrition.

RESULTS

In this cohort (68% male, mean age 59 ± 8 years), the incidence of baseline muscle wasting, defined as FFMI < P₁₀ , was 29%. Muscle wasting was present in 23 of 100 (23%) chemoradiation patients and 17 of 37 (46%) bioradiation patients (P = 0.009). Muscle-wasted patients required more unplanned hospitalizations during CRT (P = 0.035). In the chemoradiation subset, dose-limiting toxicity was significantly higher in wasted vs. non-wasted patients (57% vs. 25%, P = 0.004). Median follow-up was 32 months. Multivariate Cox regression analysis identified muscle wasting as independent unfavourable prognostic factor for overall survival [hazard ratio 2.1 (95% CI 1.1-4.1), P = 0.022] and cisplatin as favourable prognostic factor [hazard ratio 0.3 (95% CI 0.2-0.6), P = 0.001]. Weight and HGS significantly decreased during CRT/BRT, -3.7 ± 3.5 kg (P < 0.001) and -3.1 ± 6.0 kg (P < 0.001), respectively. Sixty-four per cent of the patients required TF 21 days (range 0-59) after CRT/BRT initiation. Total weight loss during CRT/BRT was significantly (P = 0.007) higher in the total oral diet group (5.5 ± 3.7 kg) compared with the TF group (3.0 ± 3.2 kg). Loss of FFM and HGS was similar in both groups.

CONCLUSIONS

In LAHNSCC patients undergoing CRT/BRT, FFMI < P₁₀ is an unfavourable prognostic factor for overall survival, treatment toxicity, and tolerance. Patients experience significant weight and FFM loss during treatment. Current TF regime attenuates weight loss but does not overcome loss of muscle mass and function during therapy. Future interventions should consider nutritional intake and additional strategies specifically targeting metabolism, loss of muscle mass, and function.

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.

Enteral Nutrition in Pediatric High-risk Head and Neck Cancer Patients Receiving Proton Therapy: Identifying Risk Factors and Quality of Life Concerns to Optimize Care

BACKGROUND

Radiotherapy for pediatric head and neck tumors often results in mucositis and pain, limiting oral intake and compromising patients' nutrition. There are little pediatric data available regarding enteral tube use and risk factors. Our objective was to estimate nutrition needs, identify risk factors contributing to nutritional decline and explore quality of life measures regarding enteral nutrition during proton radiotherapy.

PROCEDURE

Nutritional metrics and status were collected throughout radiation treatment for 32 patients. We surveyed patients/caregivers about their perceptions of enteral nutrition. Risk factors for progression to non-oral nutrition or >5% weight loss were evaluated using univariate analysis.

RESULTS

Patients who received any esophageal radiation or >30 Gy mean dose to the pharyngeal constrictors were more likely to experience >5% weight loss. These patients, as well as those who received a mean dose >30 Gy to the oropharynx or concurrent chemotherapy, were also more likely to require non-oral supplementation. Patients expressed the importance of maximizing nutrition and feared pain associated with a tube placement.

CONCLUSIONS

Pediatric patients with head and neck cancer can be risk-stratified based on clinical and dosimetric factors. This data, combined with parent and patient perceptions, is key to the development of rational guidelines.
