Long-term health-related quality of life in head and neck cancer survivors: A large multinational study.

Head and neck cancer (HNC) patients suffer from a range of health-related quality of life (HRQoL) issues, but little is known about their long-term HRQoL. This study explored associations between treatment group and HRQoL at least 5 years' post-diagnosis in HNC survivors. In an international cross-sectional study, HNC survivors completed the European Organization for Research and Treatment of Cancer (EORTC) quality of life core questionnaire (EORTC-QLQ-C30) and its HNC module (EORTC-QLQ-H&N35). Meaningful HRQoL differences were examined between five treatment groups: (a) surgery, (b) radiotherapy, (c) chemo-radiotherapy, (d) radiotherapy ± chemotherapy and neck dissection and (e) any other surgery (meaning any tumour surgery that is not a neck dissection) and radiotherapy ± chemotherapy. Twenty-six sites in 11 countries enrolled 1105 survivors. They had a median time since diagnosis of 8 years, a mean age of 66 years and 71% were male. After adjusting for age, sex, tumour site and UICC stage, there was evidence for meaningful differences (10 points or more) in HRQoL between treatment groups in seven domains (Fatigue, Mouth Pain, Swallowing, Senses, Opening Mouth, Dry Mouth and Sticky Saliva). Survivors who had single-modality treatment had better or equal HRQoL in every domain compared to survivors with multimodal treatment, with the largest differences for Dry Mouth and Sticky Saliva. For Global Quality of Life, Physical and Social Functioning, Constipation, Dyspnoea and Financial Difficulties, at least some treatment groups had better outcomes compared to a general population. Our data suggest that multimodal treatment is associated with worse HRQoL in the long-term compared to single modality.

A randomized study comparing the nutritional effects of radiotherapy with cetuximab versus cisplatin in patients with advanced head and neck cancer.

BACKGROUND: Head and neck cancer (HNC) patients have a high risk of developing malnutrition. This randomized study aimed to compare the effect of weekly cisplatin or cetuximab combined with radiotherapy on weight loss at 3 months after treatment was started. Secondary outcomes were the prevalence of malnutrition using the Global Leadership Initiative on Malnutrition (GLIM) criteria, feeding tube dependence and health related quality of life from a nutritional perspective. METHODS: Patients from the ARTSCAN III study with advanced HNC were assessed for weight, body composition, enteral tube dependence and selected quality-of-life scores (EORTC QLQ-C30 and QLQ-H&N35) at diagnosis and 6 weeks 3, 6 and 12 months after treatment initiation. RESULTS: Of the 80 patients, 38 and 42 were randomized to receive cetuximab and cisplatin treatment, respectively. There was no significant difference in weight loss at 3 months between the two study groups. However, the cetuximab group had significantly less weight loss, fewer enteral feeding tubes and better physical functioning at the end of treatment but more pain-related problems 3 months after treatment initiation. No differences between the groups were found at 6 and 12 months. The prevalence of malnutrition was not significantly different at any time point. CONCLUSION: The hypothesized benefit of concomitant treatment with cetuximab over cisplatin regarding the prevalence of malnutrition was not supported by this study.

The impact of electronic versus paper-based data capture on data collection logistics and on missing scores in thyroid cancer patients.

PURPOSE: The purpose of this study was to investigate the impact of the type of data capture on the time and help needed for collecting patient-reported outcomes as well as on the proportion of missing scores. METHODS: In a multinational prospective study, thyroid cancer patients from 17 countries completed a validated questionnaire measuring quality of life. Electronic data capture was compared to the paper-based approach using multivariate logistic regression. RESULTS: A total of 437 patients were included, of whom 13% used electronic data capture. The relation between data capture and time needed was modified by the emotional functioning of the patients. Those with clinical impairments in that respect needed more time to complete the questionnaire when they used electronic data capture compared to paper and pencil (ORadj 24.0; p = 0.006). This was not the case when patients had sub-threshold emotional problems (ORadj 1.9; p = 0.48). The odds of having the researcher reading the questions out (instead of the patient doing this themselves) (ORadj 0.1; p = 0.01) and of needing any help (ORadj 0.1; p = 0.01) were lower when electronic data capture was used. The proportion of missing scores was equivalent in both groups (ORadj 0.4, p = 0.42). CONCLUSIONS: The advantages of electronic data capture, such as real-time assessment and fewer data entry errors, may come at the price of more time required for data collection when the patients have mental health problems. As this is not uncommon in thyroid cancer, researchers need to choose the type of data capture wisely for their particular research question.

International Phase IV Field Study for the Reliability and Validity of the European Organisation for Research and Treatment of Cancer Thyroid Cancer Module EORTC QLQ-THY34.

Purpose: The aim of this study was to validate the new European Organisation for Research and Treatment of Cancer Quality of Life Thyroid Cancer Module (EORTC QLQ-THY34). Methods: We enrolled 437 thyroid cancer patients from 17 countries. One group (n = 303), undergoing treatment or best supportive care, completed the questionnaires at three time points (before therapy [t1], 6 weeks later [t2], and 6 months after t2 [t3]). A second group (survivors ≥2 years after diagnosis, n = 134) completed it at a random baseline time point and a second time 1 week later. We determined internal consistency (using Cronbach's alpha), the scale structure (with confirmatory factor analysis), and discriminant validity (using known-group comparisons). Group 1 data were used to assess responsiveness and group 2 data to determine test-retest reliability using intra-class correlations (ICC). Results: All 34 items fulfilled the criteria to be kept in the questionnaire. Cronbach's alpha was >0.70 in 8 of the 9 multi-item scales. All standardized factor loadings exceeded 0.40, confirming the proposed scale structure. The ICC was >0.70 in all scales expressing good test-retest reliability. Differences in scale scores between patients with different histology were >5 points in all scales. In all but one of the pre-specified scales (Dry Mouth), changes over time were ≥|4| points between at least two time points. Conclusion: The EORTC QLQ-THY34 with its 9 multi-item and 8 single-item scales is a reliable and valid tool to measure quality of life in thyroid cancer patients and can be used in future trials and studies.

Serious Long-Term Effects of Head and Neck Cancer from the Survivors' Point of View.

The long-term problems of head and neck cancer survivors (HNCS) are not well known. In a cross-sectional international study aimed at exploring the long-term quality of life in this population, 1114 HNCS were asked to state their two most serious long-term effects. A clinician recorded the responses during face-to-face appointments. A list of 15 example problems was provided, but a free text field was also available. A total of 1033 survivors responded to the question. The most frequent problems were 'dry mouth' (DM) (n = 476; 46%), 'difficulty swallowing/eating' (DSE) (n = 408; 40%), 'hoarseness/difficulty speaking' (HDS) (n = 169; 16%), and 'pain in the head and neck' (PHN) (n = 142; 14%). A total of 5% reported no problems. Logistic regression adjusted for age, gender, treatment, and tumor stage and site showed increased odds of reporting DM and DSE for chemo-radiotherapy (CRT) alone compared to surgery alone (odds ratio (OR): 4.7, 95% confidence interval (CI): 2.5-9.0; OR: 2.1, CI: 1.1-3.9), but decreased odds for HDS and PHN (OR: 0.3, CI: 0.1-0.6; OR: 0.2, CI: 0.1-0.5). Survivors with UICC stage IV at diagnosis compared to stage I had increased odds of reporting HDS (OR: 1.9, CI: 1.2-3.0). Laryngeal cancer survivors had reduced odds compared to oropharynx cancer survivors of reporting DM (OR: 0.4, CI: 0.3-0.6) but increased odds of HDS (OR: 7.2, CI: 4.3-12.3). This study provides evidence of the serious long-term problems among HNCS.

Fatigue in Long-Term Head and Neck Cancer Survivors From Diagnosis Until Five Years After Treatment.

OBJECTIVES: Fatigue due to cancer is a challenging symptom that might be long-lasting after cancer treatment. The aim of this study was to follow the development of fatigue among head and neck cancer (HNC) patients prospectively and longitudinally and to analyze predictors for acute and chronic fatigue. METHODS: HNC patients treated with curative intent were included at diagnosis and completed the following questionnaires multiple times, up to 5 years after treatment: the EORTC QLQ-FA12 for fatigue, EORTC QLQ-C30, and HNC-specific EORTC QLQ-H&N35 together with an anxiety and depression questionnaire. Predictors of fatigue were evaluated at 3 months and 5 years after treatment. RESULTS: Of the 311 study participants, 74% responded at the 5-year follow-up. Physical fatigue was significantly worse 3 months after treatment, while emotional and cognitive fatigue were the worst at diagnosis and at 3 months. All fatigue domains were significantly better after 1 year, and the fatigue scores remained stable from 1 until 5 years after treatment. Three months after chemoradiotherapy, physical fatigue was more significant, but no long-term differences due to treatment modalities were found. Depression and anxiety were predictors for chronic emotional fatigue, and local HN pain and swallowing problems were predictors for chronic physical fatigue. Better global quality of life at diagnosis was associated with less physical and emotional fatigue. CONCLUSION: Fatigue was worst in the short term for HNC patients and improved after 1 year, and long-term fatigue remained stable up to 5 years after treatment. A few predictors for chronic fatigue were found. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:2211-2221, 2023.

Phase III study of the European Organisation for Research and Treatment of Cancer Quality of Life cancer survivorship core questionnaire.

PURPOSE: The purpose of this study is to develop a European Organisation for Research and Treatment of Cancer Quality of Life Group (EORTC QLG) questionnaire that captures the full range of physical, mental, and social health-related quality of life (HRQOL) issues relevant to disease-free cancer survivors. In this phase III study, we pretested the provisional core questionnaire (QLQ-SURV111) and aimed to identify essential and optional scales. METHODS: We pretested the QLQ-SURV111 in 492 cancer survivors from 17 countries with one of 11 cancer diagnoses. We applied the EORTC QLG decision rules and employed factor analysis and item response theory (IRT) analysis to assess and, where necessary, modify the hypothesized questionnaire scales. We calculated correlations between the survivorship scales and the QLQ-C30 summary score and carried out a Delphi survey among healthcare professionals, patient representatives, and cancer researchers to distinguish between essential and optional scales. RESULTS: Fifty-four percent of the sample was male, mean age was 60 years, and, on average, time since completion of treatment was 3.8 years. Eleven items were excluded, resulting in the QLQ-SURV100, with 12 functional and 9 symptom scales, a symptom checklist, 4 single items, and 10 conditional items. The essential survivorship scales consist of 73 items. CONCLUSIONS: The QLQ-SURV100 has been developed to assess comprehensively the HRQOL of disease-free cancer survivors. It includes essential and optional scales and will be validated further in an international phase IV study. IMPLICATIONS FOR CANCER SURVIVORS: The availability of this questionnaire will facilitate a standardized and robust assessment of the HRQOL of disease-free cancer survivors.

Fatigue in Patients With Head and Neck Cancer Treated With Radiation Therapy: A Prospective Study of Patient-Reported Outcomes and Their Association With Radiation Dose to the Cerebellum.

Purpose: Although fatigue is a known side effect in patients with head and neck cancer (HNC) receiving radiation therapy, knowledge regarding long-term fatigue and dose-response relationships to organs at risk is scarce. The aim of this prospective study was to analyze patient-reported fatigue in patients with HNC receiving radiation therapy and to explore any possible association with organ-at-risk doses. Methods and Materials: Patients with HNC referred for curative radiation therapy were eligible for inclusion in the study. To assess patient-reported fatigue, quality of life questionnaires (European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-FA12) were distributed before treatment and 1, 3, 6, 12, 24, and 60 months after the start of treatment. Mean dose (Dmean) and near maximum dose (D2%) of the cerebellum and brain stem were evaluated in relation to baseline-adjusted fatigue scores at 3 months. Results: One hundred twenty-six patients treated with intensity modulated radiation therapy between 2008 and 2010 were available for final analysis. Female sex and age <60 years were associated with higher fatigue at baseline, whereas patients also treated with chemotherapy had reduced physical and emotional fatigue at 6 months. Physical fatigue (QLQ-FA12 scale) increased from baseline up to 3 months (29 vs 59; P < .0001) but showed no difference compared with baseline from 1 to 5 years. Emotional fatigue was significantly lower at 5 years compared with baseline (14 vs 28; P < .0001). Patients with cerebellum Dmean > 3.5 Gy had higher mean physical fatigue scores at 3 months (38 vs 27; P = .036). Conclusions: Although there is a significant increase in fatigue scores for patients with HNC up to 1 year after radiation therapy, this study showed a return to baseline levels at 5 years. A possible association was found between physical fatigue and a higher mean dose to the cerebellum.

Base of tongue squamous cell carcinomas, outcome depending on treatment strategy and p16 status. A population-based study from the Swedish Head and Neck Cancer Register.

BACKGROUND: The base of tongue squamous cell carcinoma (BOTSCC) is mainly an HPV-related tumor. Radiotherapy (EBRT) ± concomitant chemotherapy (CT) is the backbone of the curatively intended treatment, with brachytherapy (BT) boost as an option. With four different treatment strategies in Sweden, a retrospective study based on the population-based Swedish Head and Neck Cancer Register (SweHNCR) was initiated. MATERIAL AND METHODS: Data on tumors, treatment and outcomes in patients with BOTSCC treated between 2008 and 2014 were validated through medical records and updated as needed. Data on p16 status were updated or completed with immunohistochemical analysis of archived tumor material. Tumors were reclassified according to the UICC 8th edition. RESULTS: Treatment was EBRT, EBRT + CT, EBRT + BT or EBRT + CT + BT in 151, 145, 82 and 167 patients respectively (n = 545). A p16 analysis was available in 414 cases; 338 were p16+ and 76 p16-. 5-year overall survival (OS) was 68% (95% CI: 64-72%), with76% and 37% for p16+ patients and p16- patients, respectively. An increase in OS was found with the addition of CT to EBRT for patients with p16+ tumors, stages II-III, but for patients with tumor stage I, p16+ (UICC 8) none of the treatment strategies was superior to EBRT alone. CONCLUSION: In the present retrospective population-based study of BOTSCC brachytherapy was found to be of no beneficial value in curatively intended treatment. An increase in survival was found for EBRT + CT compared to EBRT alone in patients with advanced cases, stages II and III (UICC 8), but none of the regimes was significantly superior to EBRT as a single treatment modality for stage I (UICC 8), provided there was p16 positivity in the tumor. In the small group of patients with p16- tumors, a poorer prognosis was found, but the small sample size did not allow any comparisons between different treatment strategies.

Methodological approach for determining the Minimal Important Difference and Minimal Important Change scores for the European Organisation for Research and Treatment of Cancer Head and Neck Cancer Module (EORTC QLQ-HN43) exemplified by the Swallowing scale.

PURPOSE: The aim of this study was to explore what methods should be used to determine the minimal important difference (MID) and minimal important change (MIC) in scores for the European Organisation for Research and Treatment of Cancer Head and Neck Cancer Module, the EORTC QLQ-HN43. METHODS: In an international multi-centre study, patients with head and neck cancer completed the EORTC QLQ-HN43 before the onset of treatment (t1), three months after baseline (t2), and six months after baseline (t3). The methods explored for determining the MID were: (1) group comparisons based on performance status; (2) 0.5 and 0.3 standard deviation and standard error of the mean. The methods examined for the MIC were patients' subjective change ratings and receiver-operating characteristics (ROC) curves, predictive modelling, standard deviation, and standard error of the mean. The EORTC QLQ-HN43 Swallowing scale was used to investigate these methods. RESULTS: From 28 hospitals in 18 countries, 503 patients participated. Correlations with the performance status were |r|< 0.4 in 17 out of 19 scales; hence, performance status was regarded as an unsuitable anchor. The ROC approach yielded an implausible MIC and was also discarded. The remaining approaches worked well and delivered MID values ranging from 10 to 14; the MIC for deterioration ranged from 8 to 16 and the MIC for improvement from - 3 to - 14. CONCLUSIONS: For determining MIDs of the remaining scales of the EORTC QLQ-HN43, we will omit comparisons of groups based on the Karnofsky Performance Score. Other external anchors are needed instead. Distribution-based methods worked well and will be applied as a starting strategy for analyses. For the calculation of MICs, subjective change ratings, predictive modelling, and standard-deviation based approaches are suitable methods whereas ROC analyses seem to be inappropriate.

Health-Related Quality of Life, Dysphagia, Voice Problems, Depression, and Anxiety After Total Laryngectomy.

OBJECTIVES/HYPOTHESIS: The aims were to determine health-related quality of life (HRQoL), including voice problems, dysphagia, depression, and anxiety after total laryngectomy (TL), and investigate the associations between HRQoL and the late effects. STUDY DESIGN: Cross-sectional study. METHODS: 172 participants having received a TL 1.6 to 18.1 years ago for laryngeal/hypopharyngeal cancer filled in the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire, Core and Head and Neck module (EORTC QLQ-C30, EORTC QLQ-H&N35), Voice-Related Quality of Life questionnaire (V-RQOL), M.D. Anderson Dysphagia Inventory (MDADI), and Hospital Anxiety and Depression Scale (HADS) questionnaires. RESULTS: Participants scored worse than normative reference populations on all scales/items of the EORTC questionnaires, except one, and almost half of the scales/items showed a clinically relevant difference. Moderate/severe dysphagia was present in 46%, moderate/severe voice problems in 57%, depression in 16%, and anxiety in 20%. Decreasing age, increasing numbers of comorbidities, increasing voice problems, increasing dysphagia, and increasing depression symptoms, were associated with a lowered EORTC QLQ-C30 summary score. CONCLUSION: A substantial proportion of participants experienced clinically significant late effects and increasing levels of these were associated with a lowered HRQoL. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:980-988, 2022.

The effect of age on health-related quality of life for head and neck cancer patients up to 1 year after curative treatment.

OBJECTIVES: The aim was to evaluate the effect of age on health-related quality of life (HRQOL) for patients with head and neck cancer (HNC), treated with curative intent, in the Western healthcare region of Sweden. MATERIALS AND METHODS: In this prospective observational study, 311 HNC patients completed quality of life questionnaires for cancer (EORTC QLQ-C30 and EORTC QLQ-H&N35) and for older patients with cancer (EORT QLQ-ELD14) at diagnosis and 3, 6, and 12 months after start of treatment. Mean scores for patients ≥70 years old were compared to younger patients (50 to 69 years old) to assess differences in HRQOL. RESULTS: Of the 311 study participants, 105 patients were ≥70 years old (median age 76.7), of which 32 were ≥80 years of age. Most HRQOL scores were equal or better for older adult patients at 3 months after treatment, but physical function was better for younger adult patients up to 12 months after treatment. At 6 months the HRQOL was similar (older patients had less appetite loss and financial difficulties), while the oldest patients (≥80 years) had worse fatigue, role function, and feeling ill at 12 months. For the EORTC-ELD-14 questionnaire, older patients scored better for worries at diagnosis and reported more difficulties in maintaining purpose at 12 months after treatment. CONCLUSION: When curative treatment is administered, older adult patients with HNC have similar or even better HRQOL compared to younger adult patients, except for physical function, during the first year.

A national study of health-related quality of life in patients with cancer of the base of the tongue compared to the general population and to patients with tonsillar carcinoma.

BACKGROUND: This exploratory, registry-based, cross-sectional study aimed to evaluate patients' health-related quality of life (HRQOL) in a subsite of oropharyngeal cancer: cancer of the base of the tongue (CBT). METHODS: CBT patients, treated with curative intent, completed the EORTC QLQ-C30 and QLQ-H&N35 questionnaires 15 months after diagnosis. The HRQOL of CBT patients was compared to reference scores from the general population and to that of tonsillar carcinoma patients. RESULTS: The 190 CBT patients scored significantly worse than members of the general population on most scales. CBT patients with human papilloma virus (HPV)-positive tumors had significantly better HRQOL on 8 of 28 scales than HPV-negative patients. Compared to 405 tonsillar carcinoma patients, CBT patients had significantly worse HRQOL on 8 of the 28 scales, the majority local head and neck related problems. CONCLUSION: One year after treatment, CBT patients' HRQOL was significantly worse in many areas compared to that of the general population and slightly worse than that of tonsillar carcinoma patients.

Swedish National Multicenter Study on Head and Neck Cancer of Unknown Primary: Prognostic Factors and Impact of Treatment on Survival

Abstract Introduction Head and neck cancer of unknown primary (HNCUP) is a rare condition whose prognostic factors that are significant for survival vary between studies. No randomized treatment study has been performed thus far, and the optimal treatment is not established. Objective The present study aimed to explore various prognostic factors and compare the two main treatments for HNCUP: neck dissection and (chemo) radiation vs primary (chemo) radiation. Methods A national multicenter study was performed with data from the Swedish Head and Neck Cancer Register (SweHNCR) and from the patients' medical records from 2008 to 2012. Results Two-hundred and sixty HNCUP patients were included. The tumors were HPV-positive in 80%. The overall 5-year survival rate of patients treated with curative intent was 71%. Age (p< 0.001), performance status (p= 0.036), and N stage (p= 0.046) were significant factors for overall survival according to the multivariable analysis. Treatment with neck dissection and (chemo) radiation (122 patients) gave an overall 5-year survival of 73%, and treatment with primary (chemo) radiation (87 patients) gave an overall 5-year survival of 71%, with no significant difference in overall or disease-free survival between the 2 groups. Conclusions Age, performance status, and N stage were significant prognostic factors. Treatment with neck dissection and (chemo) radiation and primary (chemo) radiation gave similar survival outcomes. A randomized treatment study that includes quality of life is needed to establish the optimal treatment.

Quality of Life in Patients With Hypoparathyroidism After Treatment for Thyroid Cancer.

PURPOSE: Surgical complications such as hypoparathyroidism (HPT) or vocal cord palsy are seldom assessed when the quality of life (QOL) in thyroid cancer patients is investigated. The aim of this study was to measure the QOL difference in thyroid cancer survivors with and without HPT. METHODS: Participants for this analysis were enrolled in 13 countries from a study that pilot-tested a thyroid cancer-specific QOL instrument. They were included if they had been diagnosed with thyroid cancer at least 9 months previously. QOL was measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core (EORTC QLQ-C30) and some items on HPT symptoms (eg, tingling in fingers or toes). HPT status and other clinical data were extracted from the patients' medical charts. Comparisons of QOL domains between patients with and without HPT were performed using Mann-Whitney U test. The occurrence of HPT-related symptoms was compared using chi-square tests. Multiple ordinal regression analysis was performed to evaluate factors that might affect QOL. RESULTS: Eighty-nine patients participated in this study, 17 of whom were considered to have HPT. Patients in the HPT group reported significantly reduced QOL in 9 of the 15 scales of the EORTC QLQ-C30 compared to patients without HPT. Regression analysis showed that HPT was independently negatively associated with various scales of the QLQ-C30. Both groups showed a high prevalence of typical HPT symptoms. CONCLUSION: Thyroid cancer patients with HPT report significantly impaired QOL compared to thyroid cancer survivors without HPT. The assessment of HPT should be considered when measuring QOL in thyroid cancer patients.

Return to work after oropharyngeal cancer treatment-Highlighting a growing working-age population.

BACKGROUND: To describe the frequency of patients returning to work after treatment for oropharyngeal cancer and to identify predictors and physical barriers that might interfere with the return to work process. METHODS: Cross-sectional study including 295 patients. Data were collected regarding work/sick leave situation at 1 month before diagnosis and 15 months after diagnosis. The situation before diagnosis was retrospectively recalled by the patients. Two subscales and two single items from the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-H&N35 were used. Data were analyzed with multivariate logistic regression. RESULTS: Fifteen months after diagnosis, 212 patients (72%) were working. To be working 15 months after diagnosis was associated with working before diagnosis. Swallowing difficulties, problems talking on the telephone, and physical appearance were negatively associated with returning to work. CONCLUSIONS: The large number of individuals returning to work is encouraging for patients diagnosed with oropharyngeal cancer.

Long-Term Aspects of Quality of Life in Head and Neck Cancer Patients Treated With Intensity Modulated Radiation Therapy: A 5-Year Longitudinal Follow-up and Comparison with a Normal Population Cohort.

PURPOSE: Knowledge of long-term health-related quality of life (HRQOL) in patients with advanced head and neck cancer treated with intensity modulated radiation therapy is scarce. METHODS AND MATERIALS: HRQOL in 126 patients with advanced head and neck cancer treated with intensity modulated radiation therapy was followed longitudinally from diagnosis to 5 years after treatment with the European Organization for Research and Treatment of Cancer's QLQ-C30, the European Organization for Research and Treatment of Cancer's Head and Neck Cancer Module, and the M.D. Anderson Dysphagia Inventory. The survivors' HRQOL was compared with an age- and sex-matched normal population cohort. RESULTS: At 5 years, 73 of the 95 surviving patients had completed the study. Significant reductions in general pain (29 vs 12), head and neck (HN) pain (22 vs 14), and feeling ill (20 vs 10) were found, and emotional functioning (70 vs 83) and global quality of life (67 vs 74) improved, compared with baseline values. Conversely, dry mouth (19 vs 56), senses (8 vs 27), teeth problems (10 vs 22), opening mouth (19 vs 56), and sticky saliva (15 vs 40) were markedly worse, although significant improvements had occurred over time after treatment. Anderson Dysphagia Inventory scores >80 at 5 years indicated good swallowing function. In a subgroup analysis, dry mouth and senses were significantly better in patients treated with chemoradiotherapy. Comparison to a normal population cohort's HRQOL shows that the study group experienced a wide array of symptoms affecting their quality of life. CONCLUSIONS: The results of this large, long-term follow-up study show that a majority of patients report a reasonable quality of life 5 years after treatment and that there seems to be continuous improvement over time. Comparison with a normal population cohort, however, underlines the fact that classical side effects remain, even with improved radiation techniques. Additional emphasis on normal-tissue-sparing radiation therapy is warranted, with close attention devoted to HRQOL outcomes.

Health-related quality of life among tonsillar carcinoma patients in Sweden in relation to treatment and comparison with quality of life among the population.

BACKGROUND: The health-related quality of life (HRQOL) of tonsillar carcinoma survivors was explored to investigate any HRQOL differences associated with tumor stage and treatment. The survivors' HRQOL was also compared to reference scores from the population. METHODS: In this exploratory cross-sectional study patients were invited 15 months after their diagnosis and asked to answer two quality of life questionnaires (EORTC QLQ- C30, EORTC QLQ- HN35), 405 participated. RESULTS: HRQOL was associated with gender, with males scoring better than females on a few scales. Patients' HRQOL was more associated with treatment than tumor stage. Patients' HRQOL was worse than that in an age- and sex-matched reference group from the normal population, the largest differences were found for problems with dry mouth followed by problems with sticky saliva, senses, swallowing and appetite loss. CONCLUSIONS: The tonsillar carcinoma patients had a worse HRQOL compared to the general population one year after treatment.

International validation of the EORTC CAT Core: a new adaptive instrument for measuring core quality of life domains in cancer.

BACKGROUND: The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group (QLG) has developed computerised adaptive tests (CATs) for the 14 functional and symptom domains of the EORTC QLQ-C30 quality of life questionnaire. This is expected to optimise measurement precision, relevance to patients and flexibility. Here, we present the first international validation of the EORTC CAT Core. METHODS: A heterogeneous sample of 699 cancer patients scheduled for chemotherapy and/or radiotherapy was recruited across seven European countries. The EORTC CAT Core and all QLQ-C30 items were administered to participants before and after initiating treatment. Correlations between CAT and QLQ-C30 scores and floor/ceiling effects were calculated. Using several grouping variables, relative validity (cross-sectional known groups difference), responsiveness (changes over time) and relative sample size requirements of the CAT compared to the QLQ-C30 were estimated. RESULTS: Correlations of the CAT and QLQ-C30 ranged from 0.81 to 0.93 across domains. The mean relative reduction in floor and ceiling effects using the CAT was 42% (range 3-99%). Analyses of known groups validity and responsiveness indicated that, across domains, mean sample size requirements for the CAT were 72% and 70%, respectively, of those using the QLQ-C30. CONCLUSIONS: The EORTC CAT Core measures the same domains as the QLQ-C30 with reduced floor/ceiling effects. The CAT generally facilitated the use of smaller samples (about 30% smaller on average) without loss of power compared to the QLQ-C30. Based on this study, the EORTC QLG will release the EORTC CAT Core for general use.
