ABSTRACT To evaluate the long-term quality of life of patients treated for head and neck cancer at a single institution in a developing country.
Cross-sectional analysis of a consecutive series of patients.
Tertiary cancer center hospital in Brazil.
Eligible subjects included patients treated between 1974 and 1999 for head and neck carcinoma who had a minimum disease-free survival of 2 years and who completed a Portuguese version of the University of Washington Quality of Life (UW-QOL) questionnaire.
Descriptive analyses of the results and comparisons of the scores for each UW-QOL domain, stratified by tumor site, were performed using nonparametric tests.
Findings from 344 patients were analyzed. Of the study population, 140 (41%) had survived 2 to 5 years, 125 (36%) had survived 5 to 10 years, and 79 (23%) had survived more than 10 years since treatment. Primary tumor sites were in the oral cavity in 43.3% of cases, the oropharynx in 20.9%, the larynx in 32.0%, and the hypopharynx in 3.8%. In terms of treatment, 33.1% underwent surgery alone; 16.9%, radiotherapy alone; and 50% underwent combined treatment. Overall, 78.5% of the patients classified their own health as good or excellent. Stratified analysis showed that impairment in chewing and swallowing was more common in patients with oral and oropharyngeal tumors than in those with larynx and hypopharynx tumors, and speech impairment was more frequently related to patients with larynx and hypopharynx tumors than to those with oral and oropharynx tumors. In all tumor sites, the composite scores were significantly worse in advanced tumors than early stage tumors, but the use of combined treatment had the greatest negative impact on quality-of-life scores, after we adjusted for T and N stage with multivariable analyses (P<.001).
The Portuguese version of the UW-QOL questionnaire was an effective tool to evaluate quality of life in a Brazilian population. Although many patients reported some limitations, most reported a good to excellent long-term quality of life.

    ABSTRACT: Measuring quality of life is an important toll in the evaluation of the impact of the disease, health and treatment in a population. The identification and description of the effects due to the disease and treatment in the life of the patients may result in changes on the treatment planning and rehabilitation and so can assist both the physician and patient in deciding the treatment. In the last 15 years many questionnaires have been validated to evaluate the specific quality of life related to head and neck cancer. The questionnaires are multidimensional, evaluating the global and specific quality the life based on domains that include many aspects: physical, socio-familial, functional, emotional, and yet questions related to the treatment including appearance, pain, speech, mastication, swallowing, saliva among others. These questionnaires are mainly self-reported, it also may be done, occasionally, a trained interviewer, and reflect the effects of the disease, its treatment and the ability of the patient to copy with the disease and its sequels. The aim of this study is to present and discuss the quality of life questionnaires specific for head and neck cancer that are widely used and are validated in the Brazilian population.(AU)

    ABSTRACT: Health-related quality of life (HRQoL) associated factors are vital considerations prior to treatment decision-making for head and neck cancer patients. The study aimed to identify potential socio-demographic and clinical prognostic value of HRQoL in head and neck cancer patients in a developing country. The Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N)-V4 in Urdu language was administered among 361 head and neck cancer patients. Data were statistically tested through multivariate analysis of variance (MANOVA) and regression modeling to identify the potentially associated factors. Treatment status, tumor stage and tumor site had the strongest negative impact on patients HRQoL, with a statistically significant decrement in FACT summary scales (effect size >0.15). Moderate associated factors of HRQoL included treatment type, marital status, employment status and age (effect size range 0.06-0.15). Weak associated factors of HRQoL with a small effect size (>0.01-0.06) included tumor size and type, gender, education level and ethnicity. This study reports 12 socio-demographic and clinical variables that have a significant impact on HRQoL of head, and neck cancer patients, and that should be considered during treatment decision-making by multidisciplinary teams and also in future HRQoL studies conducted in other developing countries.

    ABSTRACT: The aim of this study is to analyze subjectively, using the SWAL-QOL questionnaire, swallowing dysfunction and associated factors after treatment with radiotherapy and chemotherapy in patients treated for head and neck cancer. This is a cross-sectional study, based on the selection of patients with tumors of the head and neck area, treated with radiotherapy with or without chemotherapy during the years 2000 to 2006 at the Oncology Institute of Juiz de Fora. The data were analyzed using SPSS 15.0 software, and were evaluated using the chi-square test to compare differences in proportions between groups. The statistical significance level was set at 5%. It was observed that with respect to foods of solid consistency, there was a statistically significant difference for mouth tumors (p<0.01), with a tendency in this group to use softer foods, easier to chew (stews, boiled vegetables, creamy soups, canned fruit). With reference to the domains of the SWAL-QOL, the location of the tumor in the mouth was statistically associated with the lowest quality of life in the symptoms domain (p<0.05). The female gender variable was associated with the lowest perceived quality of life in several domains, namely swallowing (p=0.02); fatigue (p=0.008); symptoms (p=0.009). Age (split below and above 60 years) was not associated with differences in perceived quality of life in any domain. Tumor in the mouth and the total dose of radiation in the superior fossa were associated with the lowest quality of life in the symptoms domain. The female gender variable was associated with the lowest perceived quality of life in several domains This study shows that speech therapy should maintain a presence in the teams, to then guide the rehabilitation of organic dysphonia and mechanical dysphagia possibly afflicting patients after cancer treatment with radiation therapy and chemotherapy. Key words:Quality of life, dysphagia, head and neck neoplasms, rehabilitation.
