Speech and swallowing are important components of health-related quality of life following head and neck cancer treatment. The aim of this study was to demonstrate the value of prospective multi-centre evaluation by Speech and Language Therapists and to compare health-related quality of life with speech and swallowing impairments. The University of Washington Head and Neck questionnaire version 4 (UW-QOL) and Therapy Outcome Measures (TOM) were rated before and 6 months after cancer treatment in 95 patients from 12 centres. There was deterioration in TOM scores at 6 months. Pretreatment UW-QOL swallowing was ranked equal first, with speech fourth. At 6 months speech was first and swallowing second. There were positive correlations between UW-QOL swallowing and TOM dysphagia and between UW-QOL speech and TOM laryngectomy, voice, phonology and dysarthria disorders. Both outcome measures are suitable for routine practice. Adaptation of TOM scales for use with head and neck cancer patients may improve sensitivity, validity and therapist compliance.

Few studies have examined cost issues in the field of dysphagia. This study presents cost data collected during a clinical trial in speech-language pathology, demonstrating the types of cost analyses that can be conducted and highlighting obstacles and issues facing investigators who seek to conduct economic analyses in this arena. Seventy-nine patients were enrolled in the clinical trial to assess the impact of a swallowing intervention on swallowing and speech function. The patients were at least one year past treatment for head and neck cancer. No significant intervention differences were detected in these outcomes. A companion economic analysis was conducted in 37 of these patients using patient diaries and followup with identified health care providers. Analyses indicated that (1) the intervention did not significantly reduce health care expenditures; (2) indirect costs and costs of hospitalizations are both important factors to consider during a trial; and (3) health care costs of this population are high relative to the rest of the U.S. population. Attrition from the overall study population can pose a serious threat to the viability of an economic study. The article concludes with a discussion of how these issues can be addressed in future studies.

Flexible endoscopic evaluation of swallowing with sensory testing (FEESST) is a comprehensive endoscopic assessment of the sensory and motor components of a swallow. Previous studies addressing patient safety issues with respect to FEESST included relatively small numbers of patients and paid almost no attention to patient characteristics. The purpose of this study was to determine the incidence of FEESST-related complications in the outpatient and inpatient settings and to analyze patient diagnoses that led to the performance of FEESST. We performed a prospective study of FEESST complications in 1,340 consecutive evaluations performed over a 4 1/2-year period. The primary outcome variables were incidence of epistaxis and airway compromise. The secondary outcome variable was underlying patient diagnoses. The incidence of epistaxis was 1 in 1,340 (0.07%). There were no instances of airway compromise. Stroke was the most common reason for the performance of FEESST (343; 25.6%), followed by cardiac-related dysphagia (298; 22.2%) following open heart surgery (169/298; 56.7%), heart attack, congestive heart failure, or new arrhythmia. The remaining causes were head and neck cancer (207; 15.4%), pulmonary disease (141; 10.5%), chronic neurologic disease (124; 9.3%), and acid reflux disease (80; 6.0%). We conclude that FEESST is a relatively safe procedure for the sensory and motor assessment of dysphagia in a cohort of patients with a wide variety of underlying diagnoses. The emergence of cardiac surgery as a common cause of dysphagia warrants further study.

Efforts to improve the efficacy of treatment for SCCHN have led to the use of multimodality approaches with combinations of surgery, radiotherapy and chemotherapy. Conventional head and neck radiotherapy, a standard approach for locoregionally advanced disease, is associated with a variety of well-known acute and long-term toxicities. These chronic toxicities (i.e. xerostomia, dysphagia, fibrosis) can impact negatively on patient quality of life. Altered radiation fractionation regimens that incorporate acceleration and/or hyperfractionation can improve locoregional control but also increase acute toxicities for head and neck cancer patients. Intensity modulated radiation therapy (IMRT) has emerged as a promising method for delivering effective radiation dose to head and neck tumour targets while reducing exposure of surrounding healthy tissue. Another method for improving head and neck cancer outcome with conventional radiotherapy is with the concurrent addition of chemotherapy. Indeed, chemoradiotherapy is now a standard treatment approach for locoregionally advanced disease. Molecular targeted agents, such as the epidermal growth factor receptor (EGFR) antagonist, cetuximab (Erbitux), have recently been shown to enhance the effects of radiotherapy, and reports to date suggest that this potentiation occurs without an increase in the characteristic toxicities associated with head and neck radiation.

We would like to assess the evolution of chronic dysphagia (1 year or more) following treatment for head and neck cancer. Modified barium swallow (MBS) examinations were performed in cancer-free patients who complained of dysphagia following treatment for head and neck cancer. The severity of the dysphagia was graded on a scale of 1-7. Each patient had at least 2 MBS. Severity of dysphagia was compared between the first and last MBS study to determine whether the swallowing dysfunction had returned to normal. Patients with complaint of dysphagia and normal MBS also underwent a regular barium swallow to assess the structural integrity of the pharynx and esophagus. Between 1996 and 2001, 25 patients with dysphagia underwent repeat MBS following treatment. Swallowing dysfunction did not return to normal in the majority of the patients. At a median time of 26 months following treatment (range 15-82 months), only two patient (8%) had normalization of the swallowing. The severity of dysphagia decreased in eight patients (32%), remained unchanged in 12 patients (48%), and worsened in five patients (20%). Eight patients (32%) still had aspiration problems at 12-83 months following treatment. Six patients (24%) required dilation because of pharyngeal stenosis. Three patients who required dilation had improvement of the dysphagia severity. Chronic dysphagia is a relentless process possibly due to excessive scarring. Patients with chronic dysphagia are at risk of malnutrition, and aspiration. Management of chronic dysphagia requires a team approach with nutritional support, psychological counseling, dilation, and tube feedings when indicated.

Docetaxel (DOC) has demonstrated an activity as a radiation sensitizer in head and neck cancer. We have experienced four cases of esophageal cancer treated by weekly DOC in combination with concomitant radiotherapy. Three cases of advanced esophageal cancer and a case of relapsed esophageal cancer after administration of 5-FU and CDDP were enrolled in this pilot trial. The schedule of treatment included a weekly administration of DOC (10 mg/m2/w) and six weeks of radiotherapy in 2.0 Gy daily fractions up to 60 Gy. Combination treatments were completed successfully without any side effects except a case of developed grade 1 dysphagia. Two cases showed a complete response and others showed a partial response. One case showed a complete response developed abdominal para aortic lymph node and liver recurrence 12 months after the treatment. However, the targeted lesion within radiotherapy for this patient still showed a complete response. A weekly administration of low dose DOC in combination with radiotherapy was very effective for advanced esophageal cancer. DOC has demonstrated an activity as a radiation sensitizer.

Malignant tumors of the esophagus continue to be a major health issue associated with high mortality primarily because most present with symptoms of dysphagia or anaemia. The disease at that stage is advanced and not likely curable. The big issue for squamous dysplasia and that associated with BE is that only a small proportion are discovered in surveillance programs when they are asymptomatic, either because the patient lives in a high-incidence geographical area, has a family history, previously diagnosed head and neck cancer or chronic reflux, as in Barrett's. Current endoscopic methods are hampered by the endoscopist's inability to recognize subtle topographic clues of dysplasia, sampling errors related to biopsy protocols, and confounding inflammation-induced artifacts both for the endoscopist and pathologist. What is desperately needed would be a biomarker (e.g. serological, fecal, urinary) that selects patients for endoscopy. However, such a test is not yet on the horizon. This article examines the current status in practice and research of novel optically based 'bioendoscopic' devices (i.e. fluorescence spectroscopy and imaging, confocal fluorescence microendoscopy (CFM), light scattering spectroscopy (LSS), Raman spectroscopy (RS), and immunophotodiagnostic endoscopy) which may enhance the diagnosis of dysplasia in all patients undergoing conventional white light endoscopy. Perhaps these new technologies will lead to more cost-effective diagnosis, mapping (e.g. surface), and staging (e.g. depth) of dysplasia, thereby allowing timely cure by endoscopic means (e.g. EMR and/or PDT), biological interventions (e.g. Cox-2 inhibitors) rather than esophajectomy.

Reliable measurement tools are essential to achieve rigor in dysphagia research. In order for tongue pressure to be measured accurately in the head and neck cancer population, where change in function needs to be captured over time, a reliable tool is required. Assessing the reliability of tools that are used in swallowing evaluation has been a neglected area of dysphagia research. This article evaluates and compares the reliability of two variants of the Kay Swallowing Workstation (KSW) three-bulb silicon tongue pressure array (hand-held and fixed-position) when used to capture oral tongue pressures in two groups of participants diagnosed with head and neck cancer who had not yet commenced cancer treatment. Tongue pressure data and videofluoroscopic images were collected and recorded simultaneously onto the KSW while participants swallowed set quantities of liquid and pudding boluses. Peak amplitude tongue pressures were extracted and used in analyses. Systematic and nonsystematic variability were examined using analysis of variance and intraclass correlation coefficients, respectively. The fixed-position array demonstrated better reliability than did the hand-held method. This should be further investigated with a larger participant sample.

Randomized clinical trials (RCTs) are often known as the gold standard in treatment efficacy studies. This article defines the characteristics of RCTs and the factors that investigators must consider in designing clinical trials in dysphagia. Design issues unique to behavioral treatments often used in dysphagia are discussed. Ongoing RCTs in dysphagia are described including studies of (1) the effectiveness of the Shaker exercise versus standardized treatment in patients with severe dysphagia resulting from stroke or treatment for head and neck cancer who have been nonoral for at least three months; (2) the comparative effects of nectar- and honey-thickened liquids versus chin tuck posture and in patients with dementia or Parkinson's disease with or without dementia who aspirate on thin liquids; and (3) the comparative effects of muscle exercise versus sensory postural therapy for dysphagia resulting from treatment for head and neck cancer. Issues in generalizing from the results of clinical trials are also described.

The aim of this study was to determine the feasibility of and interest in evaluation of swallowing using dynamic magnetic resonance imaging (cine-MRI) in patients with dysphagia and aspiration caused by an abnormal pharyngeal phase of swallow. A cohort of six patients previously treated for head and neck cancer with persistent dysphagia and/or aspiration were evaluated an average of 47 months after treatment. The morphology and mobility of the oral, oropharyngeal, and laryngeal structures were analyzed using cine-MRI using single-shot fast spin echo technology. The qualitative observations were compared with a clinical fiberoptic swallowing evaluation. Swallowing physiology was analyzable for dry (saliva) swallow in all patients. MRI was well-tolerated by all six patients and no clinical aspiration occurred during the MRI. In five of six cases, further information on the cause of dysphagia was obtained using cine-MRI compared with the clinical evaluation alone. In the remaining case, cine-MRI confirmed the clinical evaluation. Cine-MRI using the dry swallow technique is feasible and without risk in patients with clinical aspiration. Cine-MRI is complementary to clinical evaluation of swallowing in patients with an abnormal pharyngeal phase of swallowing resulting from treatment of cancer.
