The objective of this study is to assess swallowing and speech outcome after chemoradiation therapy for head and neck cancer, based on the patient-reported outcome measures Swallowing Quality of Life Questionnaire (SWAL-QOL) and Speech Handicap Index (SHI), both provided with cut-off scores. This is a cross-sectional study. Department of Otolaryngology/Head and Neck Surgery of a University Medical Center. Sixty patients, 6 months to 5 years after chemoradiation for head and neck squamous cell carcinoma. Swallowing Quality of Life Questionnaire (SWAL-QOL) and SHI, both validated in Dutch and provided with cut-off scores. Associations were tested between the outcome measures and independent variables (age, gender, tumor stage and site, and radiotherapy technique, time since treatment, comorbidity and food intake). Fifty-two patients returned the SWAL-QOL and 47 the SHI (response rate 87 and 78 %, respectively). Swallowing and speech problems were present in 79 and 55 %, respectively. Normal food intake was noticed in 45, 35 % had a soft diet and 20 % tube feeding. Patients with soft diet and tube feeding reported more swallowing problems compared to patients with normal oral intake. Tumor subsite was significantly associated with swallowing outcome (less problems in larynx/hypopharynx compared to oral/oropharynx). Radiation technique was significantly associated with psychosocial speech problems (less problems in patients treated with IMRT). Swallowing and (to a lesser extent) speech problems in daily life are frequently present after chemoradiation therapy for head and neck cancer. Future prospective studies will give more insight into the course of speech and swallowing problems after chemoradiation and into efficacy of new radiation techniques and swallowing and speech rehabilitation programs.

Background/purpose: To report on health-related quality-of-life (HRQoL) of patients with laryngeal cancer, treated in a randomized trial comparing accelerated radiotherapy with carbogen and nicotinamide (ARCON) against accelerated radiotherapy alone (AR)., Material/methods: HRQoL was assessed using the HRQoL Questionnaire-C30 (QLQ-C30) and the Head & Neck cancer module (QLQ-H&N35) at baseline, at completion of radiotherapy and at 6, 12, and 24months post-baseline., Results: From 269/345 patients (AR: 136/174; ARCON: 133/171) data on HRQoL were available for analysis. Moderate to severe clinical impact of the treatment was observed for nearly all items of the QLQ-C30 and QLQ-H&N35 between baseline and end-of-treatment. At 6months, scores returned to baseline level with exception of dry mouth, sticky saliva, and taste/smell. No difference between AR and ARCON was observed. At 2years from baseline, the percentage of patients reporting moderate to severe complaints of dry mouth, sticky saliva, or changes in taste/smell was 30%, 22% and 18%, respectively, while the majority of patients had no or few complaints of swallowing (79%) or speech (64%)., Conclusions: With accelerated radiotherapy, high local tumor control was obtained while maintaining good speech and swallowing function. Long-term dry mouth, sticky saliva and changes in taste/smell are limited to one quarter of patients. (ClinicalTrials.gov number, NCT00147732)., (Copyright © 2016 Elsevier Ireland Ltd.

Background and Purpose: To evaluate the course of health-related quality of life (HRQOL) from diagnosis to 2 years follow-up in patients with head and neck cancer (HNSCC) treated with chemoradiation (CRT)., Materials and Methods: 164 patients completed the EORTC QLQ-C30 and QLQ-H&N35 questionnaires 1 week before and 6 weeks and 6, 12, 18, and 24 months after CRT. Patients were compared to a reference group. A linear mixed-model analysis was used to assess changes in HRQOL over time, and whether this was associated with age, gender, comorbidity, and tumor sublocation., Results: Significant differences for the majority of HRQOL scales were observed between patient and reference group at baseline, and follow-up. The course of HRQOL was different for survivors compared to non-survivors. In survivors, improvement over time was observed (in global quality of life, physical, role, and social function, fatigue, pain, swallowing, speech, social eating, and social contacts), while in non-survivors the pattern over time was either no changes in HRQOL or a deterioration (in physical function, social eating and contacts). In both survivors and non-survivors, emotional functioning improved after treatment, but deteriorated in the longer term. Patients with comorbidity reported worse physical function, and patients with oral/oropharyngeal cancer (compared to hypopharyngeal/laryngeal cancer) reported more oral pain and sexual problems, but fewer speech problems., Conclusions: The course of HRQOL of HNSCC patients during the first 2 years after CRT is different for survivors compared to non-survivors and is associated with comorbidity and tumor subsite., (Copyright © 2014 Elsevier Ireland Ltd.

Purpose: To evaluate long-term changes in health related quality of life (HRQOL) in oral/oropharyngeal cancer survivors and their need for and use of supportive care., Methods: Between 1999 and 2001, 80 advanced oral or oropharyngeal cancer patients treated with free-flap reconstruction and postoperative radiotherapy were included in a prospective study of whom 27 patients were long-term survivors (mean 9.2 years, range 8-11 years). The HRQOL of 26 patients (response rate 96%) was assessed with the EORTC QLQ-C30 and QLQ-H&N35 questionnaires at four points in time: pretreatment (baseline), and at 6 months, 12 months (short term) and 8-11 years (long-term) follow up. A study specific questionnaire was developed to evaluate the need for and use of supportive care (allied health services, peer contact, psychosocial care, and complementary care) and was completed at the period of treatment and at long-term follow up., Results: A number of HRQOL domains worsened significantly (p < 0.01) in the long-term: emotional functioning, social functioning, swallowing, speech, taste/smell, dry mouth, sticky saliva and coughing assessed by the mixed effects statistical model. At time of treatment, the need for supportive care was the highest for a dental hygienist (77%), a physical therapist (73%), a speech therapist (42%), a dietician (38%), and a special diet (62%). At long-term follow up, the need for supportive care was limited to a dental hygienist (46%) and a physical therapist (23%). Only small differences were observed between the perceived need for and actual use of supportive care., Conclusion: A range of HRQOL domains in head and neck cancer survivors were deteriorated in the long-term compared to baseline and to the first year after treatment. At time of treatment and less frequently at long-term follow up, patients reported needing and using a variety of supportive care services., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

The authors prospectively assessed the independent association between weight loss and deterioration in quality of life (QOL) in patients treated by radiotherapy for head and neck cancer. In 533 head and neck cancer patients treated by curative radiotherapy, changes in weight and QOL were assessed between baseline (before radiotherapy) and follow-up (12 wk after the start of radiotherapy). Patients were categorized into 4 weight loss categories: 0%, 0.1%-5.0%, 5.1%-10.0%, and >10% weight loss. The association between weight loss and change in QOL was analyzed by linear regression analysis, adjusted for sociodemographic and tumor-related characteristics, and additionally for disease specific symptoms and tube feeding. Thirty percent of patients lost 0.1%-5.0% weight, 26% lost 5.1%-10.0% weight, and 24% lost >10% weight. Adjusted regression analyses showed a significant association between weight loss and deterioration of global QOL, physical functioning, social functioning, social eating, and social contact. After additional adjustment for disease-specific symptoms and tube feeding, weight loss (>10%) remained significantly associated with global QOL, social eating, and social contact (P < 0.05). More than 10% weight loss during and directly after radiotherapy has a significant impact on social eating, social contact, and QOL in head and neck cancer patients.

Purpose: The purpose of this study is to evaluate computerized monitoring of speech and swallowing outcomes and its impact on quality of life (QoL) and emotional well-being in head and neck cancer patients in an outpatient clinic., Methods: Sixty-seven patients, treated by single or multimodality treatment, completed the EORTC QLQ-C30 and QLQ-H&N35 questionnaires and the Hospital Anxiety and Depression Scale in an outpatient clinic, using a touch screen computer system (OncoQuest), at baseline (at time of diagnosis) and first follow-up (1 month after end of treatment)., Results: Tumor sites included oral cavity (n = 12), oropharynx (n = 18), hypopharynx (n = 8), and larynx (n = 29). Tumor stage included carcinoma in situ (n = 3), stage I (n = 21), stage II (n = 7), stage III (n = 15), and IV (n = 21). No speech or swallowing problems at baseline or follow-up were noted in 23 % (speech) and 41 % (swallowing) of patients. Twenty-one percent (speech) and 19 % (swallowing) had problems at baseline and returned to normal scores at follow-up, while 16 % (speech) and 19 % (swallowing) had normal scores at baseline and developed problems at follow-up. Forty percent (speech) and 21 % (swallowing) had persistent problems from baseline to follow-up. At baseline, speech problems were significantly related to tumor site and emotional distress. At baseline and follow-up, swallowing problems were significantly related to QoL and emotional distress. At follow-up, speech problems were significantly related to QoL, emotional distress, and swallowing problems., Conclusions: Monitoring speech and swallowing problems through OncoQuest in an outpatient clinic is feasible. Many patients report speech and swallowing problems, negatively affecting their QoL and emotional well-being.

Background and Purpose: The relation between health-related quality of life (HRQOL) and survival was investigated at baseline and 6 months in 80 patients with advanced oral or oropharyngeal cancer after microvascular reconstructive surgery and (almost all) adjuvant radiotherapy., Materials and Methods: Multivariate Cox regression analyses of overall and disease-specific survival were performed including sociodemographic (age, gender, marital status, comorbidity), and clinical (tumor stage and site, radical surgical, metastasis, radiotherapy) parameters, and HRQOL (EORTC QLQ-C30 global quality of life scale)., Results: Before treatment, younger age and having a partner were predictors of disease-specific survival; younger age predicted overall survival. At 6 months post-treatment, disease-specific and overall survival was predicted by (deterioration of) global quality of life solely. Global health-related quality of life after treatment was mainly influenced by emotional functioning., Conclusion: Deterioration of global quality of life after treatment is an independent predictor of survival in patients with advanced oral or oropharyngeal cancer., (Copyright © 2010 Elsevier Ireland Ltd.

Purpose: The purpose of this study was to compare intensity-modulated radiation therapy (IMRT) and three-dimensional conventional radiotherapy (3D-CRT) with regard to patient-rated xerostomia, Radiation Therapy Oncology Group (RTOG) acute and late xerostomia and health-related quality of life (HRQoL) among patients with head and neck squamous cell carcinoma (HNSCC)., Methods and Materials: Included were 241 patients with HNSCC treated with bilateral irradiation +/- chemotherapy. Since 2000, all patients treated with HNSCC were included in a program, which prospectively assessed acute and late morbidity according to the RTOG and HRQoL on a routine basis at regular intervals. Before October 2004, all patients were treated with 3D-CRT (N = 150). After clinical implementation in October 2004, 91 patients received IMRT. In this study, the differences regarding RTOG toxicity, xerostomia, and other items of HRQoL were analyzed., Results: The use of IMRT resulted in a significant reduction of the mean dose of the parotid glands (27 Gy vs. 43 Gy (p < 0.001). During radiation, Grade 2 RTOG xerostomia was significantly less with IMRT than with 3D-CRT. At 6 months, the prevalence of patient-rated moderate to severe xerostomia and Grade 2 or higher RTOG xerostomia was significantly lower after IMRT versus 3D-CRT. Treatment with IMRT also had a positive effect on several general and head and neck cancer-specific HRQoL dimensions., Conclusions: IMRT results in a significant reduction of patient- and observer-rated xerostomia, as well as other head and neck symptoms, compared with standard 3D-CRT. These differences translate into a significant improvement of the more general dimensions of HRQoL.

Purpose: To investigate the impact of treatment-related toxicity on health-related quality of life (HRQoL) among patients with head and neck squamous cell carcinoma treated with radiotherapy either alone or in combination with chemotherapy or surgery., Patients and Methods: The study sample was composed of 425 disease-free patients. Toxicity was scored according to the European Organisation for Research and Treatment of Cancer (EORTC)/Radiation Therapy Oncology Group (RTOG) late radiation-induced morbidity scoring system. HRQoL was assessed using the EORTC Quality of Life Questionnaire C30. These assessments took place at 6, 12, 18, and 24 months after completion of radiotherapy. The analysis was performed using a multivariate analysis of variance., Results: Of the six RTOG scales investigated, two significantly affected self-reported HRQoL, salivary gland (RTOG(xerostomia)) and esophagus/pharynx (RTOG(swallowing)). Although RTOG(xerostomia) was reported most frequently, HRQoL was most affected by RTOG(swallowing), particularly in the first 18 months after completion of radiotherapy., Conclusion: Late radiation-induced toxicity, particularly RTOG(swallowing) and RTOG(xerostomia), has a significant impact on the more general dimensions of HRQoL. These findings suggest that the development of new radiation-induced delivery techniques should not only focus on reduction of the dose to the salivary glands, but also on anatomic structures that are involved in swallowing.

Purpose: To investigate the impact of xerostomia on overall quality of life (QoL) outcome and related dimensions among head and neck cancer patients treated with primary radiotherapy., Methods and Materials: A total of 288 patients with Stage I-IV disease without distant metastases were included. Late xerostomia according to the Radiation Therapy Oncology Group (RTOG-xerostomia) and QoL (European Organization for Research and Treatment of Cancer QLC-C30) were assessed at baseline and every 6th month from 6 months to 24 months after radiotherapy., Results: A significant association was found between RTOG-xerostomia and overall QoL outcome (effect size [ES] 0.07, p < 0.001). A significant relationship with global QoL, all functioning scales, and fatigue and insomnia was observed. A significant interaction term was present between RTOG-xerostomia and gender and between RTOG-xerostomia and age. In terms of gender, RTOG-xerostomia had a larger impact on overall QoL outcome in women (ES 0.13 for women vs. 0.07 for men). Furthermore, in women ES on individual scales were larger, and a marked worsening was observed with increasing RTOG-xerostomia. No different ES according to age was seen (ES 0.10 for 18-65 years vs. 0.08 for >65 years). An analysis of the impact of RTOG-xerostomia on overall QoL outcome over time showed an increase from 0.09 at 6 months to 0.22 at 24 months. With elapsing time, a worsening was found for these individual scales with increasing RTOG-xerostomia., Conclusions: The results of this prospective study are the first to show a significant impact of radiation-induced xerostomia on QoL. Although the incidence of Grade > or =2 RTOG-xerostomia decreases with time, its impact on QoL increases. This finding emphasizes the importance of prevention of xerostomia.

Background: In definitive radiation therapy for head and neck cancer, clinically uninvolved cervical lymph nodes are irradiated with a so-called 'elective dose' in order to achieve control of clinically occult metastases. As a consequence of high-resolution diagnostic imaging, occult tumor volume has significantly decreased in the last decades. Since the elective dose is dependent on occult tumor volume, the currently used elective dose may be higher than necessary. Because bilateral irradiation of the neck contributes to dysphagia, xerostomia and hypothyroidism in a dose dependent way, dose de-escalation to these regions can open a window of opportunity to reduce toxicity and improve quality of life after treatment.Methods: UPGRADE-RT is a multicenter, phase III, single-blinded, randomized controlled trial. Patients to be treated with definitive radiation therapy for a newly diagnosed stage T2-4 N0-2 M0 squamous cell carcinoma of the oropharynx, hypopharynx or larynx are eligible. Exclusion criteria are recurrent disease, oncologic surgery to the head and neck area, concomitant chemotherapy or epidermal growth factor receptor inhibitors. In total, 300 patients will be randomized in a 2:1 ratio to a treatment arm with or without de-escalation of the elective radiation dose and introduction of an intermediate dose-level for selected lymph nodes. Radiation therapy planning FDG-PET/CT-scans will be acquired to guide risk assessment of borderline-sized cervical nodes that can be treated with the intermediate dose level. Treatment will be given with intensity-modulated radiation therapy or volumetric arc therapy with simultaneous-integrated boost using an accelerated fractionation schedule, 33 fractions in 5 weeks. The primary endpoint is 'normalcy of diet' at 1 year after treatment (toxicity). The secondary endpoint is the actuarial rate of recurrence in electively irradiated lymph nodes at 2 years after treatment (safety).Discussion: The objective of the UPGRADE-RT trial is to investigate whether de-escalation of elective radiation dose and the introduction of an intermediate dose-level for borderline sized lymph nodes in the treatment of head and neck cancer will result in less radiation sequelae and improved quality of life after treatment without compromising the recurrence rate in the electively treated neck.Trial Registration: ClinicalTrials.gov Identifier: NCT02442375 .

Background: Total laryngectomy with or without adjuvant (chemo)radiation often induces speech, swallowing and neck and shoulder problems. Speech, swallowing and shoulder exercises may prevent or diminish these problems. The aim of the present paper is to describe the study, which is designed to investigate the effectiveness and cost-utility of a guided self-help exercise program built into the application "In Tune without Cords" among patients treated with total laryngectomy.Methods/design: Patients, up to 5 years earlier treated with total laryngectomy with or without (chemo)radiation will be recruited for participation in this study. Patients willing to participate will be randomized to the intervention or control group (1:1). Patients in the intervention group will be provided access to a guided self-help exercise program and a self-care education program built into the application "In Tune without Cords". Patients in the control group will only be provided access to the self-care education program. The primary outcome is the difference in swallowing quality (SWAL-QOL) between the intervention and control group. Secondary outcome measures address speech problems (SHI), shoulder disability (SDQ), quality of life (EORTC QLQ-C30, QLQ-H&N35 and EQ-5D), direct and indirect costs (adjusted iMCQ and iPCQ measures) and self-management (PAM). Patients will be asked to complete these outcome measures at baseline, immediately after the intervention or control period (i.e. at 3 months follow-up) and at 6 months follow-up.Discussion: This randomized controlled trial will provide knowledge on the effectiveness of a guided self-help exercise program for patients treated with total laryngectomy. In addition, information on the value for money of such an exercise program will be provided. If this guided self-help program is (cost)effective for patients treated with total laryngectomy, the next step will be to implement this exercise program in current clinical practice.Trial Registration: NTR5255 Protocol version 4 date September 2015.

Background. Recently, the Quantitative Analysis of Normal Tissue Effect in the Clinic (QUANTEC) Group defined dose-volume constraints for the parotid glands to avoid severe xerostomia. The aim of this study was to determine if application of these QUANTEC criteria also protected against moderate-to-severe patient-rated xerostomia. Material and methods. The study population consisted of 307 head and neck cancer patients treated with primary (chemo)radiotherapy, either with 3D-CRT (56%) or with IMRT (44%). All patients participated in a standard follow-up program in which radiation-induced toxicity and quality of life were prospectively assessed. Patients who met the QUANTEC criteria were classified as low risk and otherwise as high risk. Results. In total, 41% of the patients (treated with 3D-CRT and IMRT) were classified as low risk patients. In the group treated with 3D-CRT and IMRT, it was possible to meet the QUANTEC criteria in 47% and 32% of the patients, respectively. Sparing the parotid glands with IMRT was considerably more difficult in patients with lymph node metastases and in patients with nasopharyngeal and oropharyngeal tumours. Low risk patients reported significantly less moderate-to-severe xerostomia than high risk patients. However, the predicted risk of elderly patients and patients with pre-existing minor patient-rated xerostomia at baseline was > 20%, even when the QUANTEC criteria were met. Conclusions. Significantly lower rates of radiation-induced patient-rated xerostomia were found among low risk patients treated according to the QUANTEC criteria, but these criteria do not completely protect against xerostomia. Particularly in elderly patients and patients already suffering from minor xerostomia at baseline, the QUANTEC criteria do not sufficiently protect against persistent, moderate-to-severe patient-rated xerostomia.

Abstract: Introduction: Recently, we found that swallowing dysfunction after curative (chemo) radiation (CH) RT has a strong negative impact on health-related quality of life (HRQoL), even more than xerostomia. The purpose of this study was to design a predictive model for swallowing dysfunction after curative radiotherapy or chemoradiation. Materials and methods: A prospective study was performed including 529 patients with head and neck squamous cell carcinoma (HNSCC) treated with curative (CH) RT. In all patients, acute and late radiation-induced morbidity (RTOG Acute and Late Morbidity Scoring System) was scored prospectively. To design the model univariate and multivariate logistic regression analyses were carried out with grade 2 or higher RTOG swallowing dysfunction at 6 months as the primary (SWALL6months) endpoint. The model was validated by comparing the predicted and observed complication rates and by testing if the model also predicted acute dysphagia and late dysphagia at later time points (12, 18 and 24 months). Results: After univariate and multivariate logistic regression analyses, the following factors turned out to be independent prognostic factors for SWALL6months: T3–T4, bilateral neck irradiation, weight loss prior to radiation, oropharyngeal and nasopharyngeal tumours, accelerated radiotherapy and concomitant chemoradiation. By summation of the regression coefficients derived from the multivariate model, the Total Dysphagia Risk Score (TDRS) could be calculated. In the logistic regression model, the TDRS was significantly associated with SWALL6months ((p <0.001). Subsequently, we defined three risk groups based on the TDRS. The rate of SWALL6months was 5%, 24% and 46% in case of low-, intermediate- and high-risk patients, respectively. These observed percentages were within the 95% confidence intervals of the predicted values. The TDRS risk group classification was also significantly associated with acute dysphagia (P <0.001 at all time points) and with late swallowing dysfunction at 12, 18 and 24 months (p <0.001 at all time points). Conclusion: The TDRS is a simple and validated measure to predict swallowing dysfunction after curative (CH) RT for HNC. This classification system enables identification of patients who may benefit from strategies aiming at prevention of swallowing dysfunction after curative (CH) RT such as preventive swallowing exercises during treatment and/or emerging IMRT techniques aiming at sparing anatomical structures that are involved in swallowing.

Abstract: Background and Purpose: To investigate the association between the mean salivary gland and oral cavity dose, with patient-rated moderate and severe xerostomia and sticky saliva. Patients and methods: One hundred and fifty-seven patients treated with bilateral irradiation for head and neck cancer were included. The parotid and submandibular glands and the oral cavity were delineated on plannings-CT scans. At baseline and 6 and 12 months self-reported xerostomia and sticky saliva were assessed using the EORTC QLQ-H&N35 questionnaire. Results: At 6 months a significant association between the mean parotid (MDpar) and mean submandibular dose (MDsubm) and xerostomia was observed (OR−MDpar: 1.17; P=0.002 and OR−MDsubm: 1.08; P=0.02). Between MDpar and MDsubm, a significant interaction term was present. No significant association was found with the oral cavity dose. Xerostomia was reversible depending on MDpar and MDsubm. Considering Sticky saliva, a significant association was found at 6 and 12 months with MDsubm (OR: 1.03; P<0.001). The P50 for sticky saliva increased with elapsing time. Conclusions: Both MDpar and MDsubm influence the risk of xerostomia in irradiated patients at 6 months. This probability as a function of the mean parotid dose significantly depended on the mean dose in the submandibular glands. Sticky saliva mainly depends on MDsubm. [Copyright &y& Elsevier]

Abstract: Background and purpose: To investigate the association between radiation technique with patient-rated moderate and severe xerostomia and sticky saliva. Materials and methods: One hundred and fifty patients treated with bilateral or unilateral irradiation for head and neck cancer were included. The salivary glands and the oral cavity were delineated on plannings-CT scans. Xerostomia and sticky saliva were assessed using the EORTC QLQ-H&N35 questionnaire at baseline and 6 and 12 months. Results: At 6 months a significant association between radiation technique and the mean parotid dose (MDparb) and xerostomia was observed (Odds ratio (OR)-technique: 2.55; p =0.04 and OR-MDparb: 1.04; p =0.009). Considering the individual salivary glands, only the mean dose in the contralateral parotid gland (MDparcl) is associated with xerostomia (OR: 1.04; p <0.0001). Moreover, the threshold dose for a 50% probability (P50) on xerostomia increased from 21Gy with bilateral to 44Gy for unilateral irradiation. Conclusions: Both technique and MDparb influence the risk of xerostomia in irradiated patients. Of all individual salivary glands, only MDparcl is of utmost importance for xerostomia. The shift in the P50 observed for xerostomia suggests that sparing of the contralateral parotid gland is compensated by hyperfunction of the contralateral parotid gland. [Copyright &y& Elsevier]

Objectives: The guided self-help exercise program called In Tune without Cords (ITwC) is effective in improving swallowing problems and communication among patients treated with a total laryngectomy (TL). This study investigated the cost-utility and cost-effectiveness of ITwC.Materials and Methods: Patients within 5 years after TL were included in this randomized controlled trial. Patients in the intervention group (n = 46) received access to the self-help exercise program with flexibility, range-of-motion and lymphedema exercises, and a self-care education program. Patients in the control group (n = 46) received access to the self-care education program only. Healthcare utilization (iMCQ), productivity losses (iPCQ), health status (EQ-5D-3L, EORTC QLU-C10D) and swallowing problems (SwalQol) were measured at baseline, 3- and 6-months follow-up. Hospital costs were extracted from medical files. Mean total costs and effects (quality-adjusted life-years (QALYs) or SwalQol score) were compared with regression analyses using bias-corrected accelerated bootstrapping.Results: Mean total costs were non-significantly lower (-€685) and QALYs were significantly higher (+0.06) in the intervention compared to the control group. The probability that the intervention is less costly and more effective was 73%. Sensitivity analyses with adjustment for baseline costs and EQ-5D scores showed non-significantly higher costs (+€119 to +€364) and QALYs (+0.02 to +0.03). A sensitivity analysis using the QLU-C10D to calculate QALYs showed higher costs (+€741) and lower QALYs (-0.01) and an analysis that used the SwalQol showed higher costs (+€232) and higher effects (improvement of 6 points on a 0-100 scale).Conclusion: ITwC is likely to be effective, but possibly at higher expenses.Trial Registration: NTR5255.

Objective: To investigate the effectiveness of a guided self-help exercise program on swallowing, speech, and shoulder problems in patients treated with total laryngectomy (TL).Materials and Methods: This randomized controlled trial included patients treated with TL in the last 5 years. Patients were randomized into the intervention group (self-help exercise program with flexibility, range-of-motion and lymphedema exercises and self-care education program) or control group (self-care education program). Both groups completed measurements before and 3 and 6-months after randomization. The primary outcome was swallowing problems (SWAL-QOL). Secondary outcomes were speech problems (SHI), shoulder problems (SDQ), self-management (patient activation: PAM) and health-related quality of life (HRQOL: EORTC QLQ-C30/H&N35). Adherence was defined as moderate-high in case a patient exercised >1 per day. Linear mixed model analyses were conducted to investigate the effectiveness of the intervention and to investigate whether neck dissection, treatment indication (primary/salvage TL), time since treatment, severity of problems, and preferred format (online/booklet) moderated the effectiveness.Results: Moderate-high adherence to the exercise program was 59%. The intervention group (n = 46) reported less swallowing and communication problems over time compared to the control group (n = 46) (p-value = 0.013 and 0.004). No difference was found on speech, shoulder problems, patient activation and HRQOL. Time since treatment moderated the effectiveness on speech problems (p-value = 0.025): patients within 6 months after surgery benefitted most from the intervention. Being treated with a neck dissection, treatment indication, severity of problems and format did not moderate the effectiveness.Conclusion: The guided self-help exercise program improves swallowing and communication.Trial Registration: NTR5255.
