RESUMEN
BACKGROUND: The aim of this prospective cohort study was to investigate swallowing function in relation to personal and clinical factors among patients with head and neck cancer (HNC) from diagnosis up to 2 years after treatment. METHODS: The 100 ml water swallow test was measured before treatment, and 3, 6, 12, and 24 months after treatment. Linear mixed-effects model analysis was conducted to investigate changes over time and the association with personal (sex and age) and clinical (tumor site, tumor stage, and treatment modality) factors. RESULTS: Among 128 included patients, number of swallows increased from baseline to 3 months after treatment and decreased to baseline again at 6 months after treatment. The number of swallows was associated with age and treatment modality. CONCLUSIONS: In patients with HNC, swallowing (dys)function changes over time with the worst score 3 months after treatment. A higher age and being treated with surgery are factors associated with swallowing dysfunction over time.

PURPOSE: After treatment for head and neck cancer (HNC), patients often experience major problems in masticatory function. The aim of this prospective cohort study among patients with HNC was to investigate which personal and clinical factors are associated with masticatory function from diagnosis up to 2 years after treatment with curative intent. METHODS: Masticatory function was measured using the Mixing Ability Test (MAT) before treatment (baseline), and 3, 6, 12, and 24 months after treatment. A linear mixed-effects model with a random intercept and slope was conducted to investigate changes over time and the association with personal (sex, age) and clinical (tumor site, tumor stage, treatment modality) factors as measured at baseline. RESULT: One-hundred-twenty-five patients were included. The prevalence of masticatory dysfunction was estimated at 29% at M0, 38% at M3, 28% at M6, 26% at M12, and 36% at M24. A higher (worse) MAT score was associated with age, tumor stage, tumor site, timing of assessment, and the interaction between assessment moment and tumor site. CONCLUSION: In patients with HNC, masticatory function changed over time and dysfunction was associated with a higher age, a tumor in the oral cavity, a higher tumor stage, and a shorter time since treatment. The prevalence of masticatory dysfunction ranged from 26 to 38%.

INTRODUCTION: Head and neck cancer (HNC) and its treatment often negatively impact swallowing function. The aim was to investigate the course of patient-reported swallowing problems from diagnosis to 3, 6, 12, and 24 months after treatment, in relation to demographic, clinical, and lifestyle factors. METHODS: Data were used of the Netherlands Quality of Life and Biomedical Cohort Study in head and neck cancer research (NET-QUBIC). The primary outcome measures were the subscales of the Swallowing Quality of Life Questionnaire (SWAL-QOL). Linear mixed-effects models (LMM) were conducted to investigate changes over time and associations with patient, clinical, and lifestyle parameters as assessed at baseline. RESULTS: Data were available of 603 patients. There was a significant change over time on all subscales. Before treatment, 53% of patients reported swallowing problems. This number increased to 70% at M3 and decreased to 59% at M6, 50% at M12, and 48% at M24. Swallowing problems (i.e., longer eating duration) were more pronounced in the case of female, current smoking, weight loss prior to treatment, and stage III or IV tumor, and were more prevalent at 3 to 6 months after treatment. Especially patients with an oropharynx and oral cavity tumor, and patients receiving (C)RT following surgery or CRT only showed a longer eating duration after treatment, which did not return to baseline levels. CONCLUSION: Half of the patients with HNC report swallowing problems before treatment. Eating duration was associated with sex, smoking, weight loss, tumor site and stage, and treatment modality, and was more pronounced 3 to 6 months after treatment.

INTRODUCTION: Treatment for oral cancer can impair oral functions such as mastication, which may negatively affect quality of life (QoL). In this review, an overview is provided of masticatory ability in patients treated for oral cancer. METHODS: The PubMed (MEDLINE), Embase and Cochrane databases were systematically searched for scientific literature on masticatory ability in relation to QoL in patients treated for oral cancer. Studies were included when oral cancer treatment was provided, and the University of Washington Quality of Life (UW-QoL) questionnaire was used. Risk of bias (MINORS) was independently assessed by two authors. RESULTS: The PubMed (MEDLINE), Embase and Cochrane search yielded 575 unique records of which 111 were assessed full text, and 27 studies were included. The UW-QoL mastication scores ranged from 31.9 to 97.4. There was a wide variety in methodology, patient groups, tumour site, treatment and assessment moment, to such a degree that outcome scores are difficult to compare. CONCLUSION: The wide variety in studies exploring health-related QoL in relation to mastication in oral cancer patients prevents the identification of possible relations between treatment, masticatory ability and QoL. Our findings underline the limitations in currently available literature and indicate the necessity for more comparable research.

PURPOSE: Before and after treatment for head and neck cancer (HNC), many patients have problems with mastication, swallowing, and salivary flow. The aim of this study was to investigate the association between objective test outcomes of mastication, swallowing, and salivary flow versus patient-reported outcomes (PROs) measuring mastication-, swallowing-, and salivary flow-related quality of life. METHODS: Data of the prospective cohort "Netherlands Quality of Life and Biomedical Cohort Study" was used as collected before treatment, and 3 and 6 months after treatment. Spearman's rho was used to test the association between objective test outcomes of the mixing ability test (MAT) for masticatory performance, the water-swallowing test (WST) for swallowing performance, and the salivary flow test versus PROs (subscales of the EORTC QLQ-H&N35, Swallow Quality of Life questionnaire (SWAL-QoL-NL) and Groningen Radiation-Induced Xerostomia (GRIX)). RESULTS: Data of 142 patients were used, and in total, 285 measurements were performed. No significant correlations were found between the MAT or WST and subscales of the EORTC QLQ-H&N35. Significant but weak correlations were found between the MAT or WST and 4 subscales of the SWAL-QoL-NL. Weak to moderate correlations were found between the salivary flow test and GRIX at 3 and 6 months after treatment, with the highest correlation between salivary flow and xerostomia during the day (Spearman's rho = - 0.441, p = 0.001). CONCLUSION: The association between objective test outcomes and PROs is weak, indicating that these outcome measures provide different information about masticatory performance, swallowing, and salivary flow in patients with HNC.

PURPOSE: The level of daily physical activity in patients with cancer is frequently assessed by questionnaires, such as the Physical Activity Scale for the Elderly (PASE). Objective assessments, with for example accelerometers, may be a good alternative. The aim of this study was to investigate the agreement between the PASE questionnaire and accelerometer-assessed physical activity in a large group of patients with different types of cancer. METHODS: Baseline accelerometer and PASE questionnaire data of 403 participants from the REACT (Resistance and Endurance Exercise After Chemotherapy, n = 227), the EXIST (Exercise Intervention After Stem-Cell Transplantation, n = 74), and NET-QUBIC (NEtherlands QUality of Life And Biomedical Cohort Studies In Cancer, n = 102) studies were available for the current analyses. Physical activity was assessed by the PASE questionnaire (total score) and accelerometers (total minutes per day > 100 counts). Linear mixed models regression analysis was used to assess the agreement between the PASE questionnaire and accelerometer-assessed physical activity. RESULTS: The mean (SD) PASE score was 95.9 (75.1) points and mean (SD) time in physical activity measured with the accelerometer was 256.6 (78.8) min per day. The agreement between the PASE score and the accelerometer data was significant, but poor (standardized regression coefficient (B) = 0.36, 95%CI = 0.27; 0.44, p < 0.01). CONCLUSION: Agreement between the PASE questionnaire and accelerometer-assessed physical activity was poor. The poor agreement indicates that they measure different physical activity constructs and cannot be used interchangeably to assess the level of daily physical activity in patients with cancer.

OBJECTIVE: This study assessed the test-retest reproducibility of the Utrecht mixing ability test (MAT) and the construct validity of the MAT in relation to the Mandibular Function Impairment Questionnaire (MFIQ) in patients with mandibular condylar fractures. MATERIAL AND METHODS: Twenty-six patients treated for a mandibular condylar fracture participated in this clinimetric study; all patients performed the MAT twice. Simultaneously the MFIQ was conducted. Test-retest reliability and construct validity were assessed using the intra-class correlation coefficient (ICC) and Spearman correlation, respectively. RESULTS: The ICC of the MAT was 0.906 (95% CI: 0.801-0.957), which indicates an excellent reliability. A weak correlation of 0.386 (P = .052) between the first MAT and the overall outcome of the MFIQ was found. A significant moderate correlation of 0.401 (P = .042) was found between the retest of the MAT and the overall outcome of the MFIQ. One question on the MFIQ (about yawning) showed a moderate positive correlation of 0.569 (P = .002) and 0.416 (P = .034) for the MAT test and retest, respectively. CONCLUSION: The MAT is an easy test to use in follow-up of patients. The test-retest reliability of this test is excellent in condylar trauma patients. As the validity of the MAT and the MFIQ could not be confirmed, the MFIQ may be an addition to patient's feedback about the rehabilitation process of their mandibular functioning.

BACKGROUND: Treatment of patients with head and neck cancer can result in disrupted mastication. To measure masticatory performance in people with compromised mastication, the mixing ability test (MAT) was developed. OBJECTIVE: In this study, the reliability of the MAT was evaluated in patients with head and neck cancer and healthy controls. METHODS: Thirty-four patients with head and neck cancer and 42 healthy controls performed the MAT twice on the same day. To assess reliability, the intra-class correlation coefficient (ICC2,1 ), standard error of measurement (SEM), smallest detectable change (SDC) and limits of agreement (LoA) were calculated. RESULTS: A good (ICC = 0.886) and moderate correlation (ICC = 0.525) were found for patients and healthy controls, respectively. Patients had a worse mixing ability (mean = 19.12, SD = 4.56) in comparison with healthy controls (mean = 16.42, SD = 2.04). The SEM was 0.76 in patients and 1.45 in healthy controls, with a SDC of 2.12 and 4.02, respectively. The LoA was -4.46 to 4.42 in patients and -3.65 to 4.59 in healthy controls. CONCLUSION: The MAT has a good reliability in patients with head and neck cancer and a moderate reliability in healthy controls.

BACKGROUND: The mixing ability test (MAT) as an outcome measure of masticatory performance is largely used in studies with adults, but not yet with children. OBJECTIVE: This study aimed to test the construct validity and the test-retest reliability of the MAT in children with spastic cerebral palsy (CP) and children with typical development (TD). METHOD: The results of the MAT were correlated with tongue movements, mandible movements, relative muscle contraction and clinical observation measured with ultrasound, 3D kinematics, electromyography (EMG) and relevant items of the mastication observation and evaluation (MOE) instrument, respectively. Moreover, the between-groups effect was tested. Test-retest reliability was calculated with an intra-class correlation coefficient (ICC) and standard error of measurement (SEM). RESULTS: Twenty-one children (seven children with spastic CP and 14 children with TD) participated in this study. The MAT scores showed moderate to good correlations with some variables of the tongue movements, horizontal mandible movements and occlusion duration, relative muscle contraction of the left temporalis and all six MOE items (-0.80 < r < 0.49). The MAT scores were significantly higher for children with CP (mean 22.6; SD 2.4) compared to children with TD (mean 19.9; SD 1.9). The test-retest reliability had an ICC of 0.7 and a SEM of 1.16 (±5% of the mean score). CONCLUSION: These results indicate that the MAT is suitable and complementary to ultrasound, 3D kinematics, EMG and observation to compare the masticatory performance between children with CP and children with TD, with an acceptable test-retest reliability.

BACKGROUND: Dysphagia may occur in up to 44% of patients with head and neck cancer (HNC) treated with radiation therapy and up to 84% of patients treated with surgery. To test the extent of dysphagia, the 100 mL water swallow test (WST) was developed. In this study, reliability of the 100 mL WST was determined in patients with HNC and healthy subjects. METHODS: Thirty-three patients and 40 healthy subjects performed the WST twice on the same day. To assess reliability, the intraclass correlation coefficient (ICC2,1 ), standard error of measurement, smallest detectable change, and limits of agreement were calculated. RESULTS: Good to excellent correlations were found for patients with HNC (number of swallows; ICC = 0.923, duration; ICC = 0.893), and excellent correlations for healthy subjects (number of swallows; ICC = 0.950, duration; ICC = 0.916). CONCLUSION: The 100 mL WST has a good to excellent reliability in patients with HNC and healthy subjects.
