To test a novel intervention to train swallowing to occur in the mid-to-low expiratory phase of quiet breathing to improve swallowing safety and efficiency.
Safety and efficacy non-randomized clinical trial with one-month follow-up.
Head and neck cancer (HNC) ambulatory clinics.
Thirty patients with HNC and chronic dysphagia completed the intervention. Fifteen of these patients participated in a one-month follow-up visit.
Training protocol based on hierarchy of motor skill acquisition to encourage autonomous and optimal respiratory-swallowing coordination. Visual feedback of respiratory phase and volume for swallowing initiation was provided by nasal airflow and rib cage/abdomen signals.
MAIN OUTCOME MEASURES:
Respiratory-swallow phase pattern, Modified Barium Swallow Impairment Profile™© (MBSImP) scores, Penetration Aspiration Scale (PAS) scores, M.D. Anderson Dysphagia Inventory scores RESULTS: Using visual feedback, patients were trained to initiate swallows during the mid-expiratory phase of quiet breathing and to continue to expire after swallowing. This optimal phase patterning increased significantly after treatment (p <0.0001). Changes in respiratory-swallowing coordination were associated with improvements in three MBSImP component scores: laryngeal vestibular closure (p = 0.0004), tongue base retraction (p <0.0001), and pharyngeal residue (p = 0.01). Significant improvements were also seen in PAS scores (p <0.0001). Relative to pre-treatment values, patients participating in one-month follow-up had increased optimal phase patterning (p <0.0001), improved laryngeal vestibular closure (p = 0.01), tongue base retraction (p = 0.003), and pharyngeal residue (p = 0.006) MBSImP scores, and improved PAS scores (p <0.0001).
Improvements in respiratory-swallowing coordination can be trained using a systematic protocol and respiratory phase-lung volume related biofeedback in patients with HNC and chronic dysphagia, with favorable effects on airway protection and bolus clearance.

The aim of this study was to evaluate dysphagia in patients with head and neck cancer (HNC) undergoing three-dimensional conformal radiation therapy using objective and subjective tools simultaneously and to associate the clinical correlates of dysphagia with dosimetric parameters.
Twenty patients were included in the study. The primary tumor and the involved lymph nodes (LN) were treated with 66-70 Gy, the uninvolved LN were treated with 46-50 Gy. Six swallowing structures were identified: the superior pharyngeal constrictor muscle (SPCM), the middle pharyngeal constrictor muscle (MPCM), the inferior pharyngeal constrictor muscle (IPCM), the base of tongue (BOT), the larynx and the proximal esophageal sphincter (PES). Dysphagia was evaluated using videofluoroscopy and European Organization for Research and Treatment of Cancer (EORTC) QoL questionnaire (QLQ-C30) and supplemental EORTC QoL module for HNC (QLQ-H&N35). The evaluations were performed before treatment, at 3 months and at 6 months following treatment.
On objective evaluation, the Dmax for the larynx and the sub-structures of the PCM were correlated with impaired lingual movement, BOT weakness and proximal esophageal stricture at 3 months, whereas the V65, the V70and the Dmax for the larynx was correlated with BOT weakness and the V65, the V70, the Dmax or the Dmean for the sub-structures of the PCM were correlated with impaired lingual movement, BOT weakness, reduced laryngeal elevation, reduced epiglottic inversion and aspiration at 6 months following treatment. On subjective evaluation, the V60, the Dmax and the Dmean for SPCM were correlated with QoL scores for HNSO at 3 months, whereas the V70 for SPCM were correlated with QoL scores for HNPA and the V60, the V65, the V70, the Dmax and the Dmean for SPCM were correlated with QoL scores for HNSO at 6 months following treatment.
The use of multiple dysphagia-related endpoints to complement eachother rather than to overlap with one another, as well as the use of multiple evaluations over time to represent a scale of early to late findings might provide a better insight in terms of the association of the clinical correlates of dysphagia with the dose-volume data for the dysphagia-related anatomical structures.

Dysphagia. 2014 May 21
The implication of dysphagia for people treated nonsurgically for head and neck cancer (HNC) and its detrimental effects on functioning and quality of life has been well documented. To date, however, there has been a paucity of research on the effects of dysphagia following HNC on carers, independent of the consequences of a gastrostomy. The objective of this qualitative study was to report on the experiences of carers of people with dysphagia (non-gastrostomy dependent) following nonsurgical treatment for HNC and to identify the support needs of this group. A purposive, maximum-variation sampling technique was adopted to recruit 12 carers of people treated curatively for HNC since 2007. Each participated in an in-depth interview, detailing their experience of caring for someone with dysphagia and the associated impact on their life. Thematic analysis was adopted to search the transcripts for key phases and themes that emerged from the discussions. Analysis of the transcripts revealed four themes: (1) dysphagia disrupts daily life, (2) carers make adjustments to adapt to their partner’s dysphagia, (3) the disconnect between carers’ expectations and the reality of dysphagia, and (4) experiences of dysphagia-related services and informal supports. Carers generally felt ill-prepared for their role in dysphagia management. The qualitative methodology successfully described the impact of dysphagia on the everyday lives of carers, particularly in regard to meal preparation, social events, and family lifestyle. Clinicians should provide adequate and timely training and support to carers and view carers as copartners in dysphagia management.

The purpose of this study was to assess aspiration pneumonia (AsPn) rates and predictors after chemo-irradiation for head and neck cancer.
The was a prospective study of 72 patients with stage III to IV oropharyngeal cancer treated definitively with intensity-modulated radiotherapy (IMRT) concurrent with weekly carboplatin and paclitaxel. AsPn was recorded prospectively and dysphagia was evaluated longitudinally through 2 years posttherapy by observer-rated (Common Toxicity Criteria version [CTCAE]) scores, patient-reported scores, and videofluoroscopy.
Sixteen patients (20%) developed AsPn. Predictive factors included T classification (p = .01), aspiration detected on videofluoroscopy (videofluoroscopy-asp; p = .0007), and patient-reported dysphagia (p = .02-.0003), but not observer-rated dysphagia (p = .4). Combining T classification, patient reported dysphagia, and videofluoroscopy-asp, provided the best predictive model.
AsPn continues to be an under-reported consequence of chemo-irradiation for head and neck cancer. These data support using patient-reported dysphagia to identify high-risk patients requiring videofluoroscopy evaluation for preventive measures. Reducing videofluoroscopy-asp rates, by reducing swallowing structures radiation doses and by trials reducing treatment intensity in patients predicted to do well, are likely to reduce AsPn rates.

Purpose of this review is the evaluation of speech and swallowing function after surgical treatment for advanced oral and oropharyngeal carcinoma. A systematic literature search (1993–2009), yielding 1,220 hits. The predefined criteria for inclusion in this systematic review were oral or oropharyngeal cancer, surgical treatment, speech and/or swallow function outcome, T-stage ≥ 2, patient cohort > 20, adequate description of the patient cohort in terms of tumor (sub) site, and low risk of bias (Cochrane criteria). Twelve studies fulfilled the predefined criteria. The results for speech more than 1 year after resection of oral or oropharyngeal cancer are reported to be moderate to good; although in the majority of patients speech is experienced as deviant. Overall sentence intelligibility scores are normal (92–98%). Swallowing is reported to be often already disturbed before treatment and is even more severely compromised after treatment. Aspiration rates of liquids vary from 12 to 50% and especially after oropharyngeal resection, pharyngeal transit times are delayed. Postoperative radiotherapy further increases function disturbances significantly. Critical subsites with regard to speech are the mobile tongue, and the soft palate and for swallowing, the floor of the mouth, the posterior base of tongue and the hard and soft palate. Prosthetic appliances (e.g., obturators, palatal augmentation prostheses) can diminish function losses considerably. Surgery for oral and oropharyngeal cancer yields function deficits, most notably with regard to swallowing. Series are small and outcome measurements vary. Therefore, to optimize pre-operative risk assessment, there is a need for internationally standardized outcome measurements.

The aim of this study was to evaluate nutritional status, food intake, and dysphagia in long-term head and neck cancer survivors.
Thirty-two patients with stage III-IV head and neck cancer treated by chemoradiotherapy were invited to evaluate nutritional status (malnutrition, relative weight loss), food intake (food modification; quality), and dysphagia.
At a median follow up of 44 months, 6 of 32 patients were at risk for malnutrition. Women (p = .049) and patients with high body mass index before treatment (p = .024) showed more weight loss. None of the 32 patients could eat a “full diet.” Six patients used nutritional supplements/tube feeding. Low dysphagia-related quality of life scores were significantly correlated to increased food modification (r = 0.405; p = .024).
Nutritional advice in patients with head and neck cancer is still necessary years after chemoradiation and should focus on nutritional status, food modification, and quality, in accord with recommended food groups. © 2013 Wiley Periodicals, Inc. Head Neck, 2013.

Analysis of quality of life (QOL) has revealed that preservation of swallowing, speech, and breathing functions has a direct impact on QOL and that these functions are important patient-reported outcomes. The purposes of this study were to adapt and culturally validate the M.D. Anderson Dysphagia Inventory (MDADI) to the Brazilian Portuguese language and to evaluate QOL related to dysphagia in patients treated for head and neck cancer. This was a cross-sectional study that included 72 adult patients with a mean age of 63 years who were treated for head and neck cancer. Construct validity and reliability analyses were performed through the comparison of the MDADI with three other health-related QOL questionnaires administered at the time of enrollment and MDADI application 2 weeks thereafter, respectively. Reliability was established by assuring both internal consistency (Cronbach’s α) and test–retest reliability (intraclass correlation coefficient, ICC). Test–retest reliability for the total score in the MDADI had an ICC greater than 0.795 (p < 0.001). The MDADI had significant statistical correlations with the other questionnaires. Patients treated for head and neck cancer had a mean total score of 83 on the MDADI, which is indicative of minimal limitation in overall QOL. In conclusion, the present study validates the adaptation of the MDADI to the Brazilian Portuguese language and provides another tool to evaluate the impact of dysphagia on the QOL of head and neck cancer patients.

PURPOSE: Dysphagia after chemoradiotherapy is common. The present randomized clinical trial studied the effectiveness of preventative behavioral intervention for dysphagia compared with the “usual care.” METHODS AND MATERIALS: A total of 58 head-and-neck cancer patients treated with chemoradiotherapy were randomly assigned to usual care, sham swallowing intervention, or active swallowing exercises (pharyngocise). The intervention arms were treated daily during chemoradiotherapy. The primary outcome measure was muscle size and composition (determined by T(2)-weighted magnetic resonance imaging). The secondary outcomes included functional swallowing ability, dietary intake, chemosensory function, salivation, nutritional status, and the occurrence of dysphagia-related complications. RESULTS: The swallowing musculature (genioglossus, hyoglossuss, and mylohyoid) demonstrated less structural deterioration in the active treatment arm. The functional swallowing, mouth opening, chemosensory acuity, and salivation rate deteriorated less in the pharyngocise group. CONCLUSION: Patients completing a program of swallowing exercises during cancer treatment demonstrated superior muscle maintenance and functional swallowing ability.

BACKGROUND: This study examined risk factors for dysphagia, a common and serious condition in patients with head and neck cancer, and the association between severity of dysphagia and survival. METHODS: Chart reviews were performed on patients diagnosed with head and neck cancer between January 2001 and April 2003, who had dysphagia diagnoses or swallowing evaluations. Regression analyses determined factors associated with dysphagia and the association between observed survival and severity of dysphagia. RESULTS: Almost 50% of the 407 patients had dysphagia. Risk factors included advanced stage, older age, female sex, and hypopharyngeal tumors. The most severe dysphagia ([L.] nil per os or “nothing by mouth” status), which was associated with lower survival rates, was the strongest independent predictor of survival. CONCLUSIONS: Swallowing problems should be considered when determining appropriate cancer-directed treatment and posttreatment care. Because of dysphagia’s high incidence rate and association with survival, a speech-language pathologist should be involved to ensure routine diagnostic and therapeutic swallowing interventions.

Percutaneous endoscopic gastrostomy (PEG) use is common in patients who undergo radiotherapy (RT) for head and neck cancer to maintain weight and nutrition during treatment. However, the true effect of PEG use on weight maintenance and its potential impact on long-term dysphagia outcomes have not been adequately studied. This retrospective study looked at swallowing-related outcomes among patients who received prophylactic PEG vs. those who did not, and among patients who maintained oral diets vs. partial oral diets vs. those who were nil per os (NPO). Outcomes were assessed at the end of RT and at 3, 6, and 12 months post RT. A comprehensive review of patients’ medical charts for a 6-year period yielded 59 subjects with complete data. Results showed no difference in long-term percent weight change between the prophylactic PEG patients vs. all others, or between patients who, during RT, had oral diets vs. partial oral diets vs. NPO. However, those who did not receive prophylactic PEGs and those who maintained an oral or a partial oral diet during RT had significantly better diet outcomes at all times post RT. Dependence on a PEG may lead to adverse swallowing ability in post-irradiated head and neck cancer patients possibly due to decreased use of the swallowing musculature.
