Assessment of functional outcomes in head and neck cancer

The goals of the present publication are (a) to identify standardised methods and tools applied in clinical trials and cohort studies to assess key functional aspects in HNC, using the Brief ICF Core Set for head and neck cancer (ICF-HNC) as a reference and (b) to propose a set of sound standardised methods and tools suitable to assess functional problems in HNC. This work contributed to the development of practical ICF-HNC based guidelines targeting the standardised measurement of functional outcomes in HNC follow-up and clinical research in Germany. A systematic review of randomised and clinical controlled trials, and observational studies in HNC were carried out to identify standardised methods and tools. Suitable methods and tools were then selected based on pre-defined criteria. 210 assessment methods and tools were identified in 136 studies: 146 patients reported outcomes (PRO) and 64 tools rated by health professionals. Altogether 59 tools were considered suitable to be included in guidelines: four side effects classifications, two performance status scales, 31 PROs, 10 assessment criteria for clinical examinations, seven assessment methods and tools for the evaluation of technical, equipment-based procedures and five technical, equipment-based procedures. It was possible to identify and select sound and standardised assessment methods and tools for almost all functioning areas defined in the ICF-HNC. Since no tool sufficiently covers support provision by immediate family and by health professionals as well as economic self-sufficiency, we recommend a corresponding update of existing tools.     

Nutrition in patients with head and neck cancer

Nutrition in Patients with Head and Neck Cancer. Malnutrition is common in patients with head and neck cancer. Due to natural course of disease or therapy, malnutrition may increase. This leads to a reduced prognosis, quality of life, and should be considered in early stages of the disease. First choice is an enteral feeding via a nasogastral feeding tube or a PEG. In special cases a parenteral nutrition may be necessary.     

Disability in patients with head and neck cancer

BACKGROUND: Patients with head and neck cancer often experience debilitating speech, eating, and respiratory problems as well as the psychological effects of loss of function and change in body image. These patients often become unemployed as a result of their disease process, which adds financial burden to their already stressful lives. Yet the specific factors associated with unemployment have not been systematically studied. METHODS: This multisite study used survey and chart data to determine the predictors of work-related disability. RESULTS: Of the 384 patients who were working prior to their diagnosis of head and neck cancer, 52% (n = 201) were disabled by their cancer treatment. Multivariate analysis demonstrated significant links between disability and chemotherapy (odds ratio [OR], 3.4; P <.001), neck dissection status (OR, 2.3; P =.01), pain scores (OR, 1.2; P =.01), and time since diagnosis (OR, 0.9; P =.04). CONCLUSIONS: More than half of the patients in this study were disabled by their head and neck cancer or treatment. Patients with head and neck cancer who have undergone chemotherapy or neck dissection or have high pain scores are at increased risk for disability from their cancer or their treatment. Efforts to prevent (if possible), better assess, and treat pain and other adverse effects of head and neck cancer treatments may also have the potential to reduce patient disability.     

Group psychotherapy for head and neck cancer patients

The diagnosis of cancer has a profound emotional effect on the patient. We report the two-year experience of a weekly support group attended by 142 hospitalized head and neck cancer patients and 33 family members. The major goal for the group was to provide an open forum for discussion of any problems that faced the patient. Group size was usually four to eight patients and two to four therapists. Weekly data sheets documented attendance and major themes for the group. The most common theme was anticipation of and reaction to treatment. Initial difficulties with the group included ambivalence by the professional staff, low attendance, and logistical problems. Subjective impressions of the staff were that the group improved patients' morale, patient to patient support, compliance, and decreased the rate of discharge against medical advice.     

Life-satisfaction in patients with head and neck cancer

Life-satisfaction is a measure of a patient's perception of the difference between his reality and his needs, or wants. This study reports the results of a longitudinal survey of patients’self-reported life-satisfaction following treatment for head and neck cancer. Life-satisfaction scores improved with time, and were related to pain, speech difficulty, and dysphagia. Lack of adequate family support was also important, although an uncommon problem. Treatment modality did not emerge as a significant determinant of life-satisfaction; speech difficulties were more likely to be due to articulation problems than voicing difficulty.     

Assessment of nutritional status and quality of life in patients treated for head and neck cancer

The purpose of this study was to identify tools for the assessment of nutritional status in head and neck cancer patients, to evaluate the impact of malnutrition on therapeutic management and quality of life and to propose a simple screening approach adapted to routine clinical practice. The authors conducted a review of the literature to identify tools for the assessment of nutritional status in head and neck cancer patients published in French and English. Articles were obtained from the PubMed database and from the references of these articles and selected journals, using the keywords: “nutritional assessment”, and “head and neck” and “cancer”. Anthropometric indices, laboratory parameters, dietary intake assessment, clinical scores and nutritional risk scores used in patients with head and neck cancers are presented. The relevance of these tools in clinical practice and in research is discussed, together with the links between nutritional status and quality of life. This article is designed to help teams involved in the management of patients with head and neck cancer to choose the most appropriate tools for assessment of nutritional status according to their resources and their objectives.     

Swallowing function in patients with head and neck cancer prior to treatment

OBJECTIVE: To define the site-specific swallowing dysfunctions of patients with head and neck cancer with respect to tumor site and stage by, videofluoroscopic oropharyngeal motility (OPM) study prior to initiation of treatment. DESIGN: Retrospective survey. SETTING: Academic university institution. PATIENTS: A consecutive sample of 79 patients with stage III or IV head and neck cancer without prior treatment or tracheotomy. Patients were divided into groups according to tumor site: oral cavity (n = 7), oropharynx (n = 27), larynx (n = 24), and hypopharynx (n = 10). Patients with sinonasal, nasopharyngeal, and unknown primary carcinomas served as the comparison group (n = 11). INTERVENTION: All patients underwent OPM study prior to treatment. MAIN OUTCOME MEASURES: Parameters of swallowing function, including oral impairment, pharyngeal impairment, cervical esophageal impairment, aspiration, and Swallowing Performance Status Scale (SPSS) score (a global measure of swallowing function) were extracted from the pretreatment OPM study and analyzed with reference to tumor site, T stage, and overall stage. The relations between tumor site and area or degree of dysfunction, and between stage of disease and area or degree of dysfunction were analyzed using chi2 and Fisher exact tests. RESULTS: Aspiration status, cervical esophageal impairment, and pharyngeal impairment examined as a function of disease site showed statistically significant differences between groups, with laryngeal and hypopharyngeal sites revealing the most severe dysfunctions. The SPSS score did not correlate with tumor site, T stage, or overall stage. Other OPM parameters analyzed as a function of T stage and overall stage revealed no consistent patterns. CONCLUSIONS: Hypopharyngeal and laryngeal disease sites have a high degree of pretreatment functional impairment. The SPSS score is a good global measure of swallowing dysfunction. In addition, significant site-specific dysfunctions are found when the OPM study is analyzed via its separate parameters. It is therefore critical that posttreatment function is compared with baseline pretreatment dysfunction.     

Measuring edema in irradiated head and neck cancer patients

OBJECTIVES: Edema is a common side effect of radiotherapy for head and neck cancer. Systems have been developed to record and monitor changes that occur after radiotherapy. These lack the sensitivity to record edema in specific laryngo-pharyngeal structures. The aim of this study was to develop a rating scale to measure edema in the larynx and pharynx. METHODS: This was an exploratory study to develop a new measure, with the help of an expert panel, assessing interrater and intrarater reliability. A consensus group developed the rating scale. Eleven structures and 2 spaces were identified as areas sensitive to the development of edema. The terms no, mild, moderate, and severe were used to describe the degrees of edema. The scale was piloted and then tested for interrater and intrarater reliability on 5 speech and language therapists. They viewed 25 nasendolaryngoscopic images (23 patients who had had radiotherapy and 2 healthy volunteers). The images were rated with the scale. This process was repeated 1 week later. RESULTS: Images were taken from patients with oral, oropharyngeal, nasopharyngeal, or laryngeal cancer. All had had radiotherapy or chemoradiotherapy. All raters were experienced in viewing larynges via nasendolaryngoscopy. The interrater reliability for scoring the edema rating scale was moderate (weighted kappa, 0.54). Lower levels of agreement were found for the tongue base, valleculae, pharyngeal walls, and anterior commissure. The intrarater reliability was very good (weighted kappa, 0.84). CONCLUSIONS: The edema rating scale can be scored with very good test-retest reproducibility and moderate levels of agreement between clinicians. Modifications to the method are suggested to increase interrater reliability.     

Radiotherapy in N0 head and neck cancer patients

Summary The efficacy of elective radiotherapy in N0 cancer of the oropharynx, hypopharynx and supraglottic larynx was assessed retrospectively in a large series of head and neck cancer patients treated at the Institut Curie between 1958 and 1976. Despite a significant incidence of false-negative cases accompanied by extracapsular tumor spread, radiation tissue doses of 4500–5500 cGy were highly successful in preventing nodal disease in clinically negative necks. Isolated node failure occurred in only 2% of 611 cases of oropharyngeal and pharyngolaryngeal cancer from a total group of 1646 patients and 2% of 237 N0 cases of supraglottic vestibular cancer taken from a series of 340 patients. The impact of neck status on survival and disease-free survival is discussed. Present findings show that elective irradiation of the neck is easily integrated into the radiation management of primary pharyngeal and supraglottic laryngeal cancers and results in no additional morbidity to patients so treated.Presented at the International Symposium: Diagnosis and treatment of the N0 neck of carcinomas of the upper aero-digestive tract, 18 September 1992, Göttingen, Germany     

Treatment in elderly patients with head and neck cancer

Despite the increasing number of elderly patients requiring treatment for head and neck cancer, there is insufficient available evidence about the oncological results of treatment and its tolerability in such patients. Owing to comorbidities, elderly patients often need complex evaluation and pretreatment management, which often results in their exclusion from clinical trials. The question of which patients constitute the highest-risk groups regarding treatment-related morbidity and mortality, and who can tolerate and benefit from aggressive treatment, has not been adequately studied. Biologic rather than chronologic age should be a more important factor in treatment protocols. Age-specific prospective clinical studies are needed on the treatment of head and neck cancer in elderly patients.     

Isolated pulmonary nodules in head and neck cancer patients

Not infrequently, a patient with newly diagnosed head and neck cancer is noted on preoperative chest radiography to have a solitary pulmonary nodule. It is initially unclear whether the pulmonary nodule is a benign lesion or a metastatic or primary lung malignancy. Considerable controversy exists regarding the evaluation of such patients as well as the treatment, assuming that the pulmonary lesion is malignant. We have reviewed the UCLA experience with patients who had head and neck cancers and pulmonary cancers no more than 5 years apart, and reviewed the literature on early stage lung cancer. We present a rational approach to the workup and treatment of patients with head and neck cancer and a pulmonary nodule on chest radiography.     

Measuring comorbidity in patients with head and neck cancer

BACKGROUND: Comorbidities are diseases or conditions that coexist with a disease of interest. The importance of comorbidities is that they can alter treatment decisions, change resource utilization, and confound the results of survival analysis. OBJECTIVE: The objective of this study was to determine the best comorbidity index to use in survival analysis of patients with squamous cell carcinoma of the head and neck. METHOD: Four validated indexes, with very different methodologies (i.e., the Charlson Index, the Cumulative Illness Rating Scale, the Kaplan-Feinstein Classification, the Index of Co-existent Disease), were tested using data from 379 unselected consecutive patients with complete 3-year follow-up from the Kingston Regional Cancer Center. Kaplan-Meier analysis and Cox Proportional Hazards Regression were used to stratify patients into three levels of increasing severity of comorbidity for each index. The Proportion of Variance Explained and Receiver Operating Characteristics curves were used to compare the performance of the indexes. CONCLUSION: The Kaplan-Feinstein Classification was the most successful in stratifying patients in this population.     

Aspiration in chemoradiated patients with head and neck cancer

OBJECTIVE: To review the incidence of aspiration after chemoradiation therapy in patients with head and neck cancer (HNC). DESIGN: Retrospective review. SETTING: Academic institution. PATIENTS: One hundred thirty patients with advanced HNC underwent chemoradiation therapy at our institution between 1998 and 2002 as part of a larger, multi-institutional, prospective study of induction chemotherapy followed by chemoradiation therapy; the 118 patients (91%) for whom oropharyngeal motility (OPM) study data were available are discussed in this article. MAIN OUTCOME MEASURES: Incidence of trace ( 5%) aspiration (deep laryngeal or tracheal penetration) as determined by pretreatment and posttreatment OPM studies and correlation of the findings with the patients' reported symptoms. RESULTS: Eighty-one patients (69%) underwent at least 1 OPM study demonstrating aspiration within the first year after chemoradiation therapy, with 30 (25%) demonstrating frank aspiration. Of the patients who aspirated, 61 (75%) reported no symptoms of coughing or choking (80% of trace and 67% of frank aspirators). The patients with cancer of the larynx and hypopharynx were more likely to be aspirators (P = .007 and P = .004, respectively). Of the 62 patients with available pretreatment OPM data, 33 (53%) demonstrated aspiration at baseline. CONCLUSIONS: Aspiration is highly prevalent among patients with advanced HNC at baseline and is worse in the posttreatment period after chemoradiation therapy. The majority of these patients report no symptoms. All patients with advanced HNC should undergo instrumental swallow assessment, even in the absence of symptoms, to detect subclinical aspiration and to institute therapeutic maneuvers and swallow precautions as well as to determine the safety of oral feeding.
