Measuring quality of life in patients with head and neck cancer: Update of the EORTC QLQ-H&N Module, Phase III

Toxicity and Quality of Life After Locoregional Radiotherapy in Patients With Thyroid Cancer

BACKGROUND

Locoregional external beam radiotherapy (EBRT) is selectively used in thyroid cancer patients to induce locoregional control. However, despite technological advances, EBRT remains associated with toxicities. We evaluated thyroid-cancer specific toxicities and long-term Quality of Life (QoL) post-EBRT.

METHODS

EBRT-treated thyroid cancer patients at Universal Medical Centre Groningen (2007-2023) were retrospectively evaluated (n = 66). Acute (< 6 weeks) and late (≥ 3 months) toxicities and QLQ-H&N35 results, prospectively collected as standard patient care, were analyzed (available in 24/66). Additionally, 17/66 living patients cross-sectionally completed the QLQ-H&N43 [renewed QLQ-H&N35] and SF-36-RAND-36.

RESULTS

In 24/66 patients who completed questionnaires during EBRT treatment, most severe acute toxicities occurred around week 6 (91% dermatitis, 74% pain, 70% hoarseness, 65% dysphagia). Late toxicities included persisting acute toxicities and fibrosis. Six months post-treatment, only QLQ-H&N35 domains "social eating" (p = 0.031) and "dry mouth/sticky saliva" (p = 0.025) were affected, in comparison to pre-radiation. In the 10/17 patients who completed the QLQ-H&N35 6 months post-radiation and the cross-sectionally performed QLQ-H&N43, no long-term mitigation of assessed domains was identified in a longitudinal analysis. The most advanced EBRT technique was associated with better QLQ-H&N43 scores (p = 0.047).

CONCLUSIONS

EBRT causes acute and late toxicities in most thyroid cancer patients and may be associated with a decreased QoL. As these patients generally survive for multiple years, there is a compelling need to minimize toxicities with more refined radiation techniques, such as proton therapy.

First example of airway restoration using cryopreserved aortic allograft after total laryngectomy: CARE case report

CASE DESCRIPTION

A 70 year-old woman presenting T4aN2cM0 laryngeal carcinoma first underwent total laryngectomy with airway reconstruction by cryopreserved aortic allograft. Six months after chemoradiotherapy, she underwent endoscopic surgery to create a neo-laryngopharynx.

RESULTS

At 13 months after primary surgery, day- and night-time breathing was effectively restored, with a little persistent salivary false passage, and a whispering but comprehensible voice after tracheostomy closure. Swallowing was possible for small amounts of soft food, thanks to sustained rehabilitation, although normal feeding was not achieved. The patient showed no episodes of pneumopathy. General health status was good, with no oncologic relapse.

DISCUSSION

This was the first case of laryngeal replacement by cryopreserved aortic allograft, showing progress in the decades-long aim of final tracheostomy closure. The ultimate objective is to achieve swallowing without false passage, by improving various aspects of surgical technique,without, so far as possible, making the procedures more complex by active airway protection systems.

The Role of Dysphagia on Head and Neck Cancer Patients' Quality of Life, Functional Disabilities and Psychological Distress: Outcomes of Cancer Rehabilitation from an Observational Single-Center Study

Many patients with head-and-neck cancer (HNC) suffer from speech or swallowing disorders. We investigated the impact of dysphagia on health-related quality of life (HRQOL), functioning, and distress in HNC survivors, and whether cancer rehabilitation can alleviate these conditions. Before admission (T0) and at discharge (T1) of three-week inpatient cancer rehabilitation, patient-reported outcomes were collected. HRQOL, symptoms, functioning, and psychological distress were assessed with EORTC QLQ-C30 and Hospital Anxiety and Depression Scale (HADS) questionnaires. Of 63 HNC patients, 22 had dysphagia, 23 needed no speech therapy (Control-1), and 18 needed speech therapy, but showed no symptoms of dysphagia (Control-2). Before rehabilitation, HRQOL, physical, social, and emotional functioning were significantly lower in dysphagia patients than in controls. Dysphagia patients reported more severe general symptoms including fatigue, pain, sleep disturbances, nausea/vomiting, diarrhea, and financial worries. Furthermore, the emotional and social functioning of Control-2 was significantly worse than Control-1. For all HNC patients, social, emotional, and role functioning, fatigue, nausea/vomiting, insomnia, and appetite loss significantly improved at T1. Improvements in HRQOL were most noticeable in dysphagia patients. Psychooncological counseling reduced depression in dysphagia and Control-2 patients to levels seen in the general population. In conclusion, dysphagia patients suffer severely from impaired functioning and systemic symptoms but benefit substantially from rehabilitation.

Malnutrition in patients with advanced head and neck cancer: Exploring the Global Leadership Initiative on Malnutrition (GLIM) criteria, energy balance and health-related quality of life

BACKGROUND & AIMS

Head and neck cancer (HNC) involves several tumor locations, the most common of which are the oropharynx and oral cavity. Patients with HNC are at high risk of developing malnutrition. Together with treatment, the tumor location contributes to difficulties in eating and swallowing, which can lead to a negative energy balance and weight loss. This study aimed to examine malnutrition via the Global Leadership Initiative on Malnutrition (GLIM) criteria, explore the different combinations of the GLIM criteria, study changes in body composition and body energy content and evaluate health-related quality of life (HRQoL) in patients with locally advanced HNC.

METHODS

Malnutrition was diagnosed via the GLIM criteria. Body weight, muscle mass, body fat, C-reactive protein (CRP) levels, energy intake, use of enteral feeding tubes or parenteral nutrition were assessed, and HRQoL scales from the European Organization for Research and Treatment of Cancer (EORTC), including the Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Quality of Life Questionnaire-Head and Neck 35 (QLQ-HN35), and the M.D. Anderson Dysphagia Inventory (MDADI) were completed at baseline, 6 weeks and at 3, 6 and 12 months after the start of treatment. Body composition was measured via dual-energy X-ray absorptiometry, and body energy content was calculated.

RESULTS

Eighty patients were included. The prevalence of malnutrition varied over time and peaked at the end of treatment at 71 %, and at this time, the most common combination of the GLIM criteria was weight loss + reduced food intake + inflammation (31 %), followed by weight loss + reduced muscle mass + reduced food intake + inflammation (20 %). At the end of treatment patients were in a negative energy balance, and compared to baseline, body weight, body fat, and muscle mass had decreased with 6.0 % (p<0.0001), 5.9 % (p<0.0001), and 8.0 % (p<0.0001) respectively. At the 3-month follow-up, the reduction in muscle mass had ceased, despite a negative energy balance, and patients started to regain muscle mass. At 12 months body weight had decreased with 7.4 % (p<0.0001), body fat with 18.9 % (p<0.0001), and muscle mass with 2.4 % (p<0.0001) compared to baseline. Patients with malnutrition reported significantly worse HRQoL on a majority of the 16 quality of life scales at all time points, except at the end of treatment, when no significant differences were found between malnourished and nonmalnourished patients.

CONCLUSIONS

Patients with advanced HNC receiving combined treatment experience major nutritional problems, and malnutrition is common at the end of treatment. Inflammation-driven muscle depletion during treatment is challenging, but it seems possible to recover muscle mass after treatment. Patients with malnutrition reported worse HRQoL at all time points, except at the end of treatment, when all patients' quality of life was very negatively affected.

Surgical complications and quality of life according to the extent of neck dissection in patients treated for oral squamous cell carcinoma

OBJECTIVE

Quality of life (QoL) and the degree of postoperative morbidity is an important aspect for patients suffering from oral squamous cell carcinoma (OSCC), which can be affected by several aspects of cancer treatment and especially the extent of surgical therapy. The aim of this study was to evaluate the clinical outcome and QoL in patients in relation to different types of neck dissection (ND) for OSCC.

MATERIALS AND METHODS

In this observational single center cohort study, OSCC patients who underwent primary resection and ND between 2017 and 2022 were included and assessed for postoperative complications. Furthermore, a subcohort of patients who presented in regular tumor aftercare was prospectively examined regarding QoL and shoulder functioning, using a modified version of the EORTC quality of life core questionnaire with its head and neck cancer module (EORTC-QLQ-H&N43). Differences in QoL between patients were analyzed regarding the extent of ND (selective vs. modified radical ND; ipsilateral vs. bilateral ND), adjuvant therapy and presence of postoperative complications.

RESULTS

Overall, 350 patients with a mean age of 66 years (± 11.6) were enrolled in the study. The overall complication rate was 12.6%, while extended ND procedures (modified radical ND and bilateral ND) were associated with higher complications. A subcohort of 57 patients participated in QoL assessment. There were clinically relevant differences (20 points and more in QoL) in relation to the extent of ND in the following domains: impaired swallowing of solid food, mouth opening limitation, sticky saliva, impaired smelling, impaired eating ability, impaired speech, shoulder pain and stiffness in the neck and shoulder area, while selected objects were influenced by adjuvant therapy. While patients with extended neck treatment presented with significantly more shoulder pain, there were no significant differences in shoulder functioning among the different ND modalities.

CONCLUSIONS

The results of this study provide an insight into QoL issues in relation to OSCC and may help to consult patients who are confronted at the beginning of the disease as well as by approaching selected health issues by specific functional treatment during follow-up.

CLINICAL RELEVANCE

In this study, it could be shown that extensive surgical neck treatment is associated with higher complication rates and lower quality of life, highlighting the relevance of surgical de-escalation if feasible.

Prevalence and correlates of fear of recurrence among oral and oropharyngeal cancer survivors

PURPOSE

Fear of recurrence (FoR) is a prevalent and difficult experience among cancer patients. Most research has focused on FoR among breast cancer patients, with less attention paid to characterizing levels and correlates of FoR among oral and oropharyngeal cancer survivors. The purpose was to characterize FoR with a measure assessing both global fears and the nature of specific worries as well as evaluate the role of sociodemographic and clinical factors, survivorship care transition practices, lifestyle factors, and depressive symptoms in FoR.

METHODS

Three hundred eighty-nine oral and oropharyngeal survivors recruited from two cancer registries completed a survey assessing demographics, cancer treatment, symptoms, alcohol and tobacco use, survivorship care practices, depression, and FoR.

RESULTS

Forty percent reported elevated global FoR, with similar percentages for death (46%) and health worries (40.3%). Younger, female survivors and survivors experiencing more physical and depressive symptoms reported more global fears and specific fears about the impact of recurrence on roles, health, and identity, and fears about death. Depression accounted for a large percent of the variance. Lower income was associated with more role and identity/sexuality worries, and financial hardship was associated with more role worries.

CONCLUSIONS

FoR is a relatively common experience for oral and oropharyngeal cancer survivors. Many of its correlates are modifiable factors that could be addressed with multifocal, tailored survivorship care interventions.

IMPLICATIONS FOR CANCER SURVIVORS

Assessing and addressing depressive symptoms, financial concerns, expected physical symptoms in the first several years of survivorship may impact FoR among oral and oropharyngeal cancer survivors.

Functional assessment of cancer therapy - head & neck (FACT-HN) translation and validation in Serbian

This study aimed to translate and validate the Functional Assessment of Cancer Therapy - Head & Neck (FACT-HN) in a Serbian-speaking population, assessing its psychometric properties and utility in evaluating the quality of life in head and neck cancer patients. The research focuses on determining the translated questionnaire's reliability, validity, and cultural relevance. A total of 106 Serbian-speaking head and neck cancer patients completed the translated FACT-HN, along with other validated instruments, including the EORTC QLQ-C30, EORTC QLQ-HN43, CES-D, and GAD-7. The translation followed a standard internationally accepted procedure. Psychometric analyses were conducted using confirmatory and exploratory factor analysis, Pearson correlations, and reliability measures such as Cronbach's alpha and intraclass correlation coefficients. The Serbian version of the FACT-HN showed excellent internal consistency across all subscales, with Cronbach's alpha ranging from 0.70 to 0.89. Confirmatory factor analysis confirmed the five-factor structure. Strong correlations were observed between the FACT-HN and other validated QoL measures, particularly with the EORTC QLQ-C30 and EORTC QLQ-HN43. Convergent validity was satisfactory for all components except the Social Well-Being component. The Serbian version of the FACT-HN is a valid and reliable tool for assessing the quality of life in head and neck cancer patients. It provides a comprehensive assessment of physical, social, emotional, and functional well-being, making it valuable for clinical and research applications in Serbian-speaking populations. Further research is needed to assess its sensitivity to longitudinal treatment-related changes.

Role of Oxidative Stress and Inflammation in Postoperative Complications and Quality of Life After Laryngeal Cancer Surgery

(1) Background: Laryngeal surgery due to carcinoma leads to significant tissue disruption, cellular injury, and inflammation. This leads to increased levels of reactive oxygen species (ROS), causing oxidative damage that can influence quality of life (QOL) and recovery and complicate the postoperative course. The aim of this study was to compare how postoperative quality of life and surgical complication occurrence interacted with the biomarker levels of oxidative stress (malondialdehyde, MDA; superoxide dismutase, SOD; glutathione peroxidase 1, GPX1; and catalase, CAT) and inflammation (interleukin 1, IL-1; interleukin 6, IL-6; C-reactive protein, CRP) in patients treated with conservative and radical laryngeal surgery. (2) Methods: The study included 56 patients who underwent surgical treatment for laryngeal cancer. Blood samples were collected to analyze oxidative stress and inflammation parameters before surgery and on the first and seventh days postoperatively. Serum concentrations of MDA, SOD, GPX, CAT, IL-1, IL-6, and CRP were measured using coated enzyme-linked immunosorbent assay (ELISA) kits. EORTC QLQ-H&H43 questionnaire was used to measure the QOL of patients. (3) Results and Conclusions: T stage, pain intensity, and the extent of the surgical procedure were established as significant predictive factors for QOL in multivariate analysis. There was a significant positive correlation between surgical complication occurrence and preoperative values of GPX and MDA, but significant predictors of surgical complication occurrence on the 7th postoperative day were SOD and MDA values (p < 0.05).

The european organisation for research and treatment of cancer head and neck cancer module (EORTC QLQ-HN43): Estimates for minimal important difference and minimal important change

INTRODUCTION

Minimal important change estimates (MIC) are useful for interpreting results of clinical research with quality of life (QoL) as an endpoint. For the European Organisation for Research and Treatment of Cancer head and neck cancer module, the EORTC QLQ-HN43, no such thresholds are established.

METHODS

Head and neck cancer patients under active treatment (n = 503) from 15 countries completed the EORTC QLQ-HN43 three times (t1: before treatment, t2: three months after t1, t3: six months after t1). A subgroup completed a Subjective Significance Questionnaire (SSQ), indicating experienced change from the previous time point in four QoL domains. QoL was assumed to deteriorate after t1 and improve again until t3. The MIC was established using the average of mean differences in SSQ groups (MICmean) and estimates based on logistic regressions (MICpredict). Additionally, minimal detectable changes (MDC) were computed using 0.5 standard deviation and standard error of the mean.

RESULTS

For swallowing, speech, dry mouth, and global QoL, the MIC for deterioration were 13, 14, 26, and 10 respectively. The MIC for improvement were 8 (swallowing), 6 (dry mouth), and 5 (global QoL); no MIC for speech improvement can be presented because of insufficient correlation between change score and anchor. The MDC estimates for deterioration were 15, 14, 15, and 11. For improvement, the MDC estimates were 13, 14, 14, and 11.

CONCLUSIONS

Our results underline that no single MIC or MDC can be applied to all EORTC QLQ-HN43 scales, and that the MIC for deterioration seems larger than those for improvement.

Feasibility of individualized home exercise programs for patients with head and neck cancer-study protocol and first results of a multicentre single-arm intervention trial (OSHO #94)

INTRODUCTION

Patients with head and neck cancer (PwHNC) benefit from targeted exercise interventions: symptom relief, compensation for dysfunction, improvement in quality of life (QoL). Data on acceptance physical interventions in PwHNC are rare. The 'OSHO #94' trial investigates the short- and medium-term effects of individualized home exercise in PwHNC on QoL, physical activity and functionality. The study includes a feasibility phase (proof of concept) in order to evaluate the acceptance. Here we present the study protocol as well as the feasibility results.

METHODS AND ANALYSIS

This prospective, multicentre, single-arm intervention study includes PwHNC ≥18 years of age in aftercare or palliative care with stable remission under immunotherapy. The study opened in January 01, 2021, with estimated completion by December 31, 2024. The PwHNC receive an individualized home exercise program consisting of mobilization, coordination, strengthening and stretching exercises. This should be carried out at least three times a week over 12 weeks for 15 to 30 minutes, supplemented by aerobic training two to three times a week for 30 minutes (intervention). Once weekly telephone calls with a physiotherapist are performed. Subsequently, there is a 12-week follow-up (FU) without exercise specifications/contact. Outcomes are measured before and after the intervention and following the FU. Primary outcome of the feasibility phase (n = 25) was the determination of the dropout rate during the intervention with a termination cut off if more than 30% PwHNC withdrew premature. The primary outcome of the OSHO #94' trial (N = 53) is the change in global QoL score from pre- to post-intervention (EORTC QLQ-C30). Secondary outcomes include clinical and patient-reported measures, training details as well as functional diagnostic data (e.g. level of physical activity, training frequency, flexibility, fall risk and aerobic performance).

RESULTS

25 PwHNC were enrolled onto the feasibility cohort. Only16% (4/25 patients) did not complete the study. Therefore, recruitment of PwHNC was continued. The dropout rate was adjusted from 30% (N = 60) to 20% (N = 53, calculated sample size n = 42 PwHNC and 20% (n = 11) to dropout).

CONCLUSIONS

Individualized home exercise programs in PwHNC in aftercare seem feasible. Consequently, the aim is now to evaluate the short and medium-term effects of individualized home exercise.

Remote assessment of cognition and quality of life following radiotherapy for nasopharyngeal carcinoma: deep-learning-based predictive models and MRI correlates

PURPOSE

Irradiation of the brain regions from nasopharyngeal carcinoma (NPC) radiotherapy (RT) is frequently unavoidable, which may result in radiation-induced cognitive deficit. Using deep learning (DL), the study aims to develop prediction models in predicting compromised cognition in patients following NPC RT using remote assessments and determine their relation to the quality of life (QoL) and MRI changes.

METHODS

Seventy patients (20-76 aged) with MRI imaging (pre- and post-RT (6 months-1 year)) and complete cognitive assessments were recruited. Hippocampus, temporal lobes (TLs), and cerebellum were delineated and dosimetry parameters were extracted. Assessments were given post-RT via telephone (Telephone Interview Cognitive Status (TICS), Telephone Montreal Cognitive Assessment (T-MoCA), Telephone Mini Addenbrooke's Cognitive Examination (Tele-MACE), and QLQ-H&N 43). Regression and deep neural network (DNN) models were used to predict post-RT cognition using anatomical and treatment dose features.

RESULTS

Remote cognitive assessments were inter-correlated (r > 0.9). TLs showed significance in pre- and post-RT volume differences and cognitive deficits, that are correlated with RT-associated volume atrophy and dose distribution. Good classification accuracy based on DNN area under receiver operating curve (AUROC) for cognitive prediction (T-MoCA AUROC = 0.878, TICS AUROC = 0.89, Tele-MACE AUROC = 0.919).

CONCLUSION

DL-based prediction models assessed using remote assessments can assist in predicting cognitive deficit following NPC RT. Comparable results of remote assessments in assessing cognition suggest its possibility in replacing standard assessments.

IMPLICATIONS FOR CANCER SURVIVORS

Application of prediction models in individual patient enables tailored interventions to be provided in managing cognitive changes following NPC RT.

PET-CT-guided, symptom-based, patient-initiated surveillance versus clinical follow-up in head neck cancer patients (PETNECK2): study protocol for a multicentre feasibility study and non-inferiority, randomised, phase III trial

BACKGROUND

Approximately 40% of treated head and neck cancer (HNC) patients develop recurrence. The risk of recurrence declines with time from treatment. Current guidelines recommend clinical follow-up every two months for the first two years after treatment, with reducing intensity over the next three years. However, evidence for the effectiveness of these regimes in detecting recurrence is lacking, with calls for more flexible, patient-centred follow-up strategies.

METHODS

PETNECK2 is a UK-based multi-centre programme examining a new paradigm of follow-up, using positron emission tomography-computed tomography (PET-CT)-guided, symptom-based, patient-initiated surveillance. This paradigm is being tested in a unblinded, non-inferiority, phase III, randomised controlled trial (RCT). Patients with HNC, one year after completing curative intent treatment, with no clinical symptoms or signs of loco-regional or distant metastasis will be randomised using a 1:1 allocation ratio to either regular scheduled follow-up, or to PET-CT guided, patient-initiated follow-up. Patients at a low risk of recurrence (negative PET-CT) will receive a face-to-face education session along with an Information and Support (I&S) resource package to monitor symptoms and be in control of initiating an urgent appointment when required. The primary outcome of the RCT is overall survival. The RCT also has an in-built pilot, a nested QuinteT Recruitment Intervention (QRI), and a nested mixed-methods study on patient experience and fear of cancer recurrence (FCR). An initial, single-arm feasibility study has been completed which determined the acceptability of the patient-initiated surveillance intervention, the completion rates of baseline questionnaires, and optimised the I&S resource prior to implementation in the RCT.

DISCUSSION

We hypothesise that combining an additional 12-month post-treatment PET-CT scan and I&S resource will both identify patients with asymptomatic recurrence and identify those at low risk of future recurrence who will be empowered to monitor their symptoms and seek early clinical follow-up when recurrence is suspected. This change to a patient-centred model of care may have effects on both quality of life and fear of cancer recurrence.

Patient-reported outcome measures for dysphagia in head and neck cancer: A systematic review and appraisal of content validity and internal structure

Dysphagia is a major head and neck cancer (HNC) issue. Dysphagia-related patient-reported outcome measures (PROMs) are critical for patient-centred assessment and intervention tailoring. This systematic review aimed to derive a comprehensive inventory of HNC dysphagia PROMs and appraise their content validity and internal structure. Six electronic databases were searched to February 2023 for studies detailing PROM content validity or internal structure. Eligible PROMs were those developed or validated for HNC, with ≥20% of items related to swallowing. Two independent raters screened citations and full-text articles. Critical appraisal followed COSMIN guidelines. Overall, 114 studies were included, yielding 39 PROMs (17 dysphagia-specific and 22 generic). Of included studies, 33 addressed PROM content validity and 78 internal structure. Of all PROMs, only the SOAL met COSMIN standards for both sufficient content validity and internal structure. Notably, the development of 18 PROMs predated the publication of COSMIN standards. In conclusion, this review identified 39 PROMs addressing dysphagia in HNC, of which only one met COSMIN quality criteria. Given that half of PROMs were developed prior to COSMIN guidelines, future application of current standards is needed to establish their psychometric quality.

A core outcome set for patient-reported dysphagia for use in head and neck cancer clinical trials: An international multistakeholder Delphi study

BACKGROUND

Measuring dysphagia-related patient-reported outcomes (PROs) in Head and Neck Cancer (HNC) patients is challenging due to dysphagia's multidimensional impact, causing inconsistency in outcome reporting. To address this issue, this study derived a consensus-based core outcome set (COS) for patient-reported dysphagia in HNC clinical trials where swallowing is a primary or secondary endpoint.

METHODS

A sample of HNC clinicians, researchers, patients, and caregivers participated in a 2-Round Delphi technique. A Delphi survey, containing a comprehensive list of dysphagia-related PROs, was developed. In Round 1, participants rated item importance on a 5-point scale. Items rated ≥4 by >70% advanced to Round 2, where a consensus meeting addressed items with varied opinions, and the Delphi survey with remaining items was completed. Items rated ≥4 by >70% formed the final COS.

RESULTS

Forty-five participants from nine countries were recruited. After Round 1, 40 items were excluded and 64 advanced to Round 2. After Round 2, a 7-outcome COS was established, comprising the domains of dysphagia symptoms, health status and quality of life.

CONCLUSION

This study achieved consensus among HNC stakeholders on essential dysphagia PROs for HNC clinical trials. It is advisable to include these 7-core concepts in clinical trials involving people with HNC to facilitate treatment comparisons and data synthesis.

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.

Impact of fosaprepitant in the prevention of nausea and emesis in head and neck cancer patients undergoing cisplatin-based chemoradiation: a pilot prospective study and a review of literature

PURPOSE

Cisplatin-based chemoradiotherapy (CRT) is standard treatment for head and neck squamous cell carcinoma (HNSCC). However, IMRT may increase chemotherapy-induced nausea and vomiting (CINV). The purpose of this study is to investigate the effect of fosaprepitant in preventing CINV.

METHODS

An infusion of 150 mg fosaprepitant was given through a 30 min. We assessed acute toxicity using CTCAE v.4 and the incidence of CINV using the FLIE questionnaire. The evaluation of CINV was done at the second and fifth weeks of CRT and 1 week after the end. The EORTC QLQ-HN 43 questionnaire was administered before treatment beginning (baseline), at second (T1) and fifth (T2) weeks. A dosimetric analysis was performed on dorsal nucleus of vagus (DVC) and area postrema (AP).

RESULTS

Between March and November 2020, 24 patients were enrolled. No correlation was found between nausea and DVC mean dose (p = 0.573), and AP mean dose (p = 0.869). Based on the FLIE questionnaire, patients reported a mean score of 30.5 for nausea and 30 for vomiting during week 2 and 29.8 for nausea and 29.2 for vomiting during week 5. After treatment ended, the mean scores were 27.4 for nausea and 27.7 for vomiting. All patients completed the EORTC QLQ-HN 43. Significantly higher scores at T2 assessment than baseline were observed.

CONCLUSIONS

The use of fosaprepitant in preventing CINV reduced incidence of moderate to severe nausea and vomiting. No correlation has been found between nausea and median dose to DVC and AP.

Psychometric analysis of Marathi version of an updated European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module (EORTC QLQ-H&N43)

BACKGROUND

The aim of this study was to perform a psychometric analysis of the Marathi version of an updated European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module (EORTC QLQ-H&N43) in patients of head and neck squamous cell carcinoma (HNSCC).

MATERIAL AND METHODS

After an institutional ethics committee approval and linguistic validation, the Marathi version of EORTC QLQ-H&N43 was served to consecutive eligible, Marathi-speaking HNSCC patients of oral cavity, oropharynx, hypopharynx and larynx, registered from August 2019 to March 2021 and who consented to the study. Performance status scale was used for perceptive assessment of organ function. Psychometric analysis was performed using SYSTAT v. 12 (Cranes software, Bengaluru).

RESULTS

A total of 129 patients participated in the study with a median age of 67 years and the man-to-woman ratio of 100:29. The commonest sub-site reported was the oral cavity (61.24%) and the majority were in stage IV disease (69.76%). Ninety patients completed the questionnaire before being started on active oncology treatment at our center. 39 patients completed the questionnaire at pre-treatment and first follow-up. The questionnaire was filled on their own (module) by 32.55% of patients while 67.44% of patients required some kind of assistance (schedule). Internal consistency was moderate to high. The criterion and construct validities were acceptable. The questionnaire was sensitive to change with stage and time. No significant difference was observed in module versus schedule subgroup except for 2 out of 19 item-scales.

CONCLUSION

Marathi translation of EORTC QLQ-H&N43 is a sensitive, reliable and valid tool when applied to patients of HNSCC. It can be considered as a schedule.

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.

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.

[Patient-reported outcomes in head and neck cancer treatment: relevance, challenges, and benefit]

Next to overall survival, quality of life is becoming more and more pivotal for cancer patients. The various domains of quality of life are complex and have different value to each patient. However, not only patients but also health care professionals, the pharmaceutical industry, and regulatory bodies ask: How can quality of life be reliably ascertained in clinical trials? For this purpose, carefully developed and validated specific questionnaires are needed: the patient-reported outcome measures (PROMs). A key challenge is to define how results based on PROMs can be used for shared decision-making. Next to clinical factors such as health and nutritional status, quality of life acts as a prognostic factor for overall survival in cancer. Thus, it is crucial to take quality of life into account in daily clinical practice.

Treatment of supraglottic squamous cell carcinoma with advanced technologies: observational prospective evaluation of oncological outcomes, functional outcomes, quality of life and cost-effectiveness (SUPRA-QoL)

BACKGROUND

Over the past decade, therapeutic options in head and neck supraglottic squamous cell carcinoma have constantly evolved. The classical total laryngectomy has been partially replaced by alternative organ- and function-sparing techniques with the same prognosis but less morbidity, such as Radiotherapy, Transoral Laser Microsurgery (TLM) and Trans-Oral Robotic Surgery (TORS). Up to now, a prospective comparison of these innovant techniques has not been conducted.

METHODS/DESIGN

We will conduct an original international multicentric prospective nonrandomized clinical trial to compare the efficacy between these treatments (Arm 1: Radiotherapy ± chemotherapy; Arm 2: TLM and Arm 3: TORS) with 4 classes of outcomes: quality of life (QoL), oncological outcomes, functional outcomes and economic resources. The population will include cT1-T2 /cN0-N1/M0 supraglottic squamous cell carcinoma. The primary outcome is a Clinical Dysphagia QoL evaluation assessed by the MD Anderson Dysphagia questionnaire. Secondary outcomes include others QoL evaluation, oncological and functional measures and cost parameters. The sample size needs to reach 36 patients per arm (total 108).

DISCUSSION

In the current literature, no prospective head-to-head trials are available to compare objectively these different treatments. With the increase of highly efficient treatments and the increase of oncological survival, it is imperative also to develop management strategies that optimize QoL and functional results. We will conduct this innovate prospective trial in order to obtain objective data in these two main issues.

Enhancing Self-care Among Oral Cancer Survivors: Protocol for the Empowered Survivor Trial

BACKGROUND

Survivors of oral cavity and oropharyngeal cancer frequently experience difficulties in swallowing; tasting; speaking; chewing; and maintaining comfortable movements of the head, neck, and shoulder. Engagement in regular self-care can reduce further loss of function and mitigate late effects. Despite the substantial self-care requirements, there are no empirically based interventions to enhance the skills and confidence of these survivors in managing their ongoing care.

OBJECTIVE

The aim of this study is to describe the rationale and methodology for a randomized controlled trial evaluating Empowered Survivor (ES) versus Springboard Beyond Cancer, a general web-based program for cancer survivors, on self-efficacy in managing care, preparedness for managing survivorship, and health-related quality of life (QOL).

METHODS

This study will recruit a total of 600 individuals who were diagnosed with oral cavity or oropharyngeal cancer in the past 3 years and are currently cancer free primarily from state cancer registries; these individuals will be randomly assigned to either the ES or Springboard Beyond Cancer condition. The participants complete measures of self-efficacy in managing care, preparedness for survivorship, health-related QOL, and engagement in oral self-examination and head and neck strengthening and flexibility exercises at baseline and 2 and 6 months after baseline. The primary aim of this study is to evaluate the impact of ES versus Springboard Beyond Cancer on self-efficacy, preparedness, and health-related QOL. The secondary aim is to examine the mediators and moderators of ES's impact on self-efficacy in managing care, preparedness, and health-related QOL at 6 months. The exploratory aim is to conduct a process evaluation of ES to identify potential oncology or community settings for future implementation.

RESULTS

Multilevel modeling will be used to examine whether there are significant differences between the ES and Springboard Beyond Cancer interventions over time. Mediational models will evaluate the indirect effects of ES on outcomes. Quantitative analyses will evaluate the predictors of ES use, and qualitative analyses will evaluate the preferred timing and settings for the implementation of ES.

CONCLUSIONS

This randomized controlled trial evaluates a completely web-based intervention, ES, versus a general web-based program for cancer survivors, Springboard Beyond Cancer, on self-efficacy in managing care, preparedness for managing survivorship, and health-related QOL and identifies the putative mediators and moderators of the intervention's effects. If an effect on the primary outcomes is illustrated, the next step could be an implementation trial to evaluate the intervention's uptake in and impact on an oncology care setting or nonprofit organizations.

A prospective observational cohort study examining the development of head and neck lymphedema from the time of diagnosis

INTRODUCTION

Head and neck lymphedema can occur in the internal or external structures of the head and neck region. Little is known about the development of this condition over the course of treatment for head and neck cancer. This study aimed to observe the development of internal and external lymphedema from diagnosis to 12 weeks postacute treatment.

METHODS

A single center, prospective observational cohort study assessed participants for external lymphedema, internal lymphedema, quality of life, and symptom burden. Assessments were conducted prior to starting radiotherapy (RT), at the end of RT, 6 and 12 weeks after RT.

RESULTS

Forty-six participants were recruited. External lymphedema as measured by percentage water content, increased from 41.9 at baseline (95% CI: 39.3-44.4) to 50.4 (95% CI: 46.0-54.8) at 12 weeks following RT (p-value < .001). After adjusting for changes in weight and participant age at baseline, a general increase in tape measurements was observed over time with significant increases from baseline to 12 weeks post-RT for all measurement points. By 12 weeks post-RT, all participants had lymphedema present in eight of 13 internal sites assessed.

CONCLUSIONS

Internal and external head and neck lymphedema was observed to increase from baseline to 12 weeks after completion of RT without abatement. People with head and neck cancer should be educated about the potentially extended duration of this treatment side effect. Further research is required to determine the point at which swelling symptoms recede.

Digital surgery group versus traditional experience group in head and neck reconstruction: a retrospective controlled study to analyze clinical value and time-economic-social effect

Objective

Discuss the application value of digital surgical technology in the reconstruction of head and neck defects after tumor resection and comprehensively evaluate time-economic-benefit cost.

Methods

A retrospective analysis of head and neck cancer patients who underwent reconstructive operations in head and neck surgery at Sichuan Cancer Hospital from January 2015 to January 2021 was performed. According to the inclusion and exclusion criteria, a total of 52 cases were included, including 25 cases using digital surgery (DS) and 27 cases using the conventional surgery (CS). The clinical-pathological characteristics, postoperative complications, functional aesthetic evaluation indexes, and time-cost-satisfaction evaluation indexes between the two groups were compared and statistically analyzed. Typical cases using digital surgery were shared.

Results

Outcomes between the two groups were comparable, and there was no significant difference in survival outcome and follow-up time between the two groups (P > 0.05). There was no significant difference between the two groups in the defect size, pathological type, other major clinicopathological features, or operation-related indicators (P > 0.05). The incidence of titanium plate displacement, deformation or exposure, and facial scar deformity in the DS group was significantly lower than that in the CS group (P < 0.05). However, there was no significant difference in other short-term or long-term complications (P > 0.05). The incidence of dysphagia and eating disorders in the DS group was significantly reduced (P < 0.05). The speech and social functions were improved, but not significantly (P > 0.05). Meanwhile, there was no significant difference in the evaluation index of facial aesthetics in this study (P > 0.05). Furthermore, the total operation time, preparation time of bone flap from the donor site, osteotomy time, and reconstruction time in the DS group were significantly lower than those in the traditional operation group (P < 0.05), but the shaping time and vascular anastomosis time of recipient area could not be shortened (P > 0.05). In addition, there was no significant difference in total hospitalization days between the DS group and CS group (P > 0.05), but the time of ICU treatment and postoperative intravenous nutrition support in the DS group were shorter than those in the CS group (P < 0.05). In particular, the preoperative doctor-patient communication of the DS group was more effective, and the treatment satisfaction of patients including their families was higher after operation (P < 0.05).

Conclusion

Comprehensive application of digital surgical technology (CAD, CAM, VR, MA, etc.) in the reconstruction of the head and neck after tumor resection is feasible in clinical practice, which can not only improve the accuracy of repair, decrease some surgical complications, better preserve and improve patient’s diet and speech function, and reduce the operation and hospitalization time, but also increase the treatment cost. Furthermore, it is conducive to doctor-patient communication and improves patient satisfaction.

Oral health related quality of life in long-term survivors of head and neck cancer compared to a general population from the seventh Tromsø study

Background

Both the incidence and survival rate of head and neck cancer (HNC) is increasing, making quality of life of HNC survivors an important issue.

Methods

In this cross-sectional study we compared the oral health related quality of life (OHRQoL) of long-term HNC survivors to that of a general population cohort from the seventh survey of the Tromsø study with the Oral Impact on Daily Performances questionnaire. Comparisons were done with frequency analyses and cross tabulation. We also assessed OHRQoL’s association to sociodemographic and oral health related variables in both cohorts as well as with cancer related variables in the HNC cohort with regression analyses.

Results

The HNC survivors had four times the risk of reporting problems with daily performances compared with the general population cohort. The ability to eat and enjoy food was most frequently affected in both cohorts. Moderate-poor self-rated dental health and general health as well as high frequency of dental visits were significantly associated with poorer OHRQoL. To have a history of oral or pharyngeal cancer was associated with more problems than having a history of laryngeal cancer.

Conclusions

Our study shows that HNC treatment is associated with a strong and lasting impairment of OHRQoL, highlighting the need to find less toxic, yet effective ways to treat the disease, and to provide easy access to expert dental care at all stages of the disease to minimize morbidity. Given the widespread side effects of cancer treatment, a multidisciplinary approach might be required to improve the OHRQoL of HNC survivors.

Analysis of Outcomes of Pharyngo-laryngo-esophagectomy and Reconstruction with Longitudinal Comparison in a Single Institution

Advanced hypopharyngeal tumours present complex clinical challenges, and where resection is attempted, there is a requirement for major reconstruction. Despite advances in surgical technique, outcomes remain poor for this patient group, and optimum treatment has yet to be established. We aimed to assess the treatment and outcomes of patients in our institution in the context of previous studies. All patients from 2008 to 2018 who underwent surgical management for hypopharyngeal tumours with pharyngo-laryngo-esophagectomy and flap-based reconstruction were included in the study. Demographic and outcome data were collected, and patient-reported outcomes were solicited from surviving patients using the EORTC QLQ H&N 43 questionnaire. Thirty patients were assessed, in which 12 had gastric pull-ups, 16 had free jejunum flaps, and 2 had free anterolateral thigh flaps. There was a 38% five-year survival rate. Overall, the rates of stricture (10.7%) and fistula (7.1%) were low. The majority of patients (53.6%) returned to a normal diet within three months with a soft or puree diet in 35.7% of patients. Some form of speech was possible in 92.9% of patients. The average questionnaire score for surviving patients was 87.3, with good outcomes related to eating and swallowing, but poorer outcomes for speech and communication. This study showed that outcomes for patients receiving complex reconstruction following hypopharyngeal tumour resection are improving over time. There is still scope for improvement of patient outcomes and refinement of optimum surgical management strategies.

Head and neck lymphoedema-research challenges during the COVID-19 pandemic

Management of secondary head and neck lymphoedema has undergone little research investigation. Its treatment is time and labour intensive and involves multiple therapeutic modalities without a clear understanding of which is most effective. This study aimed to determine the feasibility of a randomised controlled trial comparing two therapeutic modalities to manage head and neck lymphoedema. The secondary objective was to evaluate the clinical effects of these treatments. Participants were randomised to receive treatment with manual lymphatic drainage or compression over 6 weeks, with the primary outcome-percentage tissue water-measured 12 weeks after treatment. Six participants were recruited until the study was ceased due to restrictions imposed by the COVID-19 pandemic. Some 86% of required attendances were completed. Percentage tissue water increased in all participants at 12 weeks. No consistent trends were identified between internal and external lymphoedema. The small number of people recruited to this study informs its feasibility outcomes but limits any conclusions about clinical implications.

Effects of an Indomethacin Oral Spray on Pain Due to Oral Mucositis in Cancer Patients Treated With Radiotherapy and Chemotherapy: A Double-Blind, Randomized, Placebo-Controlled Trial (JORTC-PAL04)

CONTEXT

Oral mucositis (OM) pain due to anticancer chemo- and radiotherapy has a very negative impact on patient quality of life. However, no high-quality studies have been performed regarding the analgesic efficacy of indomethacin (IM) oral spray for OM pain.

OBJECTIVES

This randomized, placebo-controlled, double-blind trial aimed to evaluate the analgesic efficacy of IM oral spray for OM pain due to anticancer chemo- and radiotherapy.

METHODS

From July 2015 to December 2016, we enrolled adult cancer patients with OM pain that was due to anticancer chemo- or radiotherapy and was rated 4 or higher on Brief Pain Inventory (BPI) Item 5. Patients were randomly assigned in a 1:1 ratio to receive either IM oral spray or placebo. The primary endpoint was the change in the BPI Item 6 ("current pain") score from before to 30 minutes after treatment. Secondary endpoints were the areas under the curves of BPI Item 6 at 15, 60, 120, 180, and 240 minutes after treatment; five items related to meals and conversation from the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire, Head and Neck Module 35; the Clinical Global Impressions-Improvement (CGI-I) scale; and adverse events.

RESULTS

A total of 60 patients were assigned to receive IM oral spray (n = 33) or placebo spray (n = 27). The average change in the BPI item 6 score from before to 30 minutes after treatment was -1.85 (95% confidence interval: -2.37 to -1.32) in the IM spray group and -0.59 (-1.02 to -0.16) in the placebo group, indicating a significant difference (-1.26, -1.94 to -0.57, P < 0.01). The pain improvement persisted for 180 minutes. The intergroup differences in ability to drink liquids, ease in conversing, and CGI-I were all significant (P = 0.03, P = 0.02, and P < 0.01, respectively). No serious adverse events were reported.

CONCLUSION

IM oral spray alleviated short-term OM pain due to anticancer chemo- and radiotherapy, and may reduce the difficulty in eating meals.

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.

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.

The Head and Neck Survivorship Tool (HN-STAR) Trial (WF-1805CD): A protocol for a cluster-randomized, hybrid effectiveness-implementation, pragmatic trial to improve the follow-up care of head and neck cancer survivors

Survivors of head and neck cancer (HNC) can have multiple health concerns. To facilitate their care, we developed and pilot-tested a clinical informatics intervention, HN-STAR. HN-STAR elicits concerns online from HNC survivors prior to a routine oncology clinic visit. HN-STAR then presents tailored evidence-based clinical recommendations as a clinical decision support tool to be used during the visit where the oncology clinician and survivor select symptom management strategies and other actions. This generates a survivorship care plan (SCP). Online elicitation of health concerns occurs 3, 6, and 9 months after the clinic visit, generating an updated SCP each time. HN-STAR encompasses important methods of improving survivorship care (e.g., needs assessment, tailored interventions, dissemination of guidelines) and will be evaluated in a pragmatic trial to maximize external validity. This hybrid type 1 implementation-effectiveness trial tests HN-STAR effectiveness while studying barriers and facilitators to implementation in community oncology practices within the National Cancer Institute Community Oncology Research Program. Effectiveness will be measured as differences in key survivorship outcomes between HNC participants who do and do not use HN-STAR over one year after the clinic visit. The primary endpoint is HNC-specific quality of life; other outcomes include patient-centered measures and receipt of guideline-concordant care. Implementation outcomes will be assessed of survivors, providers, and clinic stakeholders. The hybrid design will provide insight into a dose-response relationship between the extent of implementation fidelity and effectiveness outcomes, as well as how to incorporate HN-STAR into standard practice outside the research setting.

The eHealth self-management application 'Oncokompas' that supports cancer survivors to improve health-related quality of life and reduce symptoms: which groups benefit most?

BACKGROUND

Oncokompas is a web-based self-management application that supports cancer survivors to monitor their health-related quality of life (HRQOL) and symptoms, and to obtain personalised feedback and tailored options for supportive care. In a large randomised controlled trial among survivors of head and neck cancer, colorectal cancer, and breast cancer and (non-)Hodgkin lymphoma, Oncokompas proved to improve HRQOL, and to reduce several tumour-specific symptoms. Effect sizes were however small, and no effect was observed on the primary outcome patient activation. Therefore, this study aims to explore which subgroups of cancer survivors may especially benefit from Oncokompas.

MATERIALS AND METHODS

Cancer survivors (n = 625) were randomly assigned to the intervention group (access to Oncokompas, n = 320) or control group (6 months waiting list, n = 305). Outcome measures were HRQOL, tumour-specific symptoms, and patient activation. Potential moderators included socio-demographic (sex, age, marital status, education, employment), clinical (tumour type, stage, time since diagnosis, treatment modality, comorbidities), and personal factors (self-efficacy, personal control, health literacy, Internet use), and patient activation, mental adjustment to cancer, HRQOL, symptoms, and need for supportive care, measured at baseline. Linear mixed models were performed to investigate potential moderators.

RESULTS

The intervention effect on HRQOL was the largest among cancer survivors with low to moderate self-efficacy, and among those with high personal control and those with high health literacy scores. Cancer survivors with higher baseline symptom scores benefitted more on head and neck (pain in the mouth, social eating, swallowing, coughing, trismus), and colorectal cancer (weight) specific symptoms.

DISCUSSION

Oncokompas seems most effective in reducing symptoms in head and neck cancer and colorectal cancer survivors who report a higher burden of tumour-specific symptoms. Oncokompas seems most effective in improving HRQOL in cancer survivors with lower self-efficacy, and in cancer survivors with higher personal control, and higher health literacy.

Oral and ocular late effects in head and neck cancer patients treated with radiotherapy

A broader understanding of oral and ocular late effects in head and neck cancer (HNC) patients who underwent intensity-modulated radiotherapy (IMRT) may provide valuable information in follow-up and improve quality of life. Twenty-nine HNC patients treated at least 6 months earlier and 30 age-matched controls were recruited. After completing several questionnaires: Oral Health Impact Profile-14 (OHIP-14), Shortened Xerostomia Inventory (SXI), Ocular Surface Disease Index (OSDI) and McMonnies Dry Eye questionnaire (MDEQ), participants underwent oral and ocular examinations. Oral examination included clinical oral dryness score (CODS) and secretion rates of unstimulated and stimulated saliva (UWS, SWS). Ocular examination included tear film break-up time, Schirmer test and ocular surface staining. The patients had more problems related to dry mouth than controls based on CODS and SXI, and more complaints of dry eye disease based on OSDI and MDEQ. UWS and SWS rates and oral health related quality of life were significantly lower in the patient group. Subjective oral dryness (SXI) correlated significantly with subjective ocular dryness (OSDI and MDEQ). Our study demonstrates that HNC patients treated with IMRT experience late effects in terms of xerostomia and ocular dryness underlining the importance of interdisciplinary approach in the evaluation and follow-up of HNC patients.

Health-Related Quality of Life Outcomes in Head and Neck Cancer: Results From a Prospective, Real-World Data Study With Brazilian Patients Treated With Intensity Modulated Radiation Therapy, Conformal and Conventional Radiation Techniques

PURPOSE

To compare global health-related quality of life (HRQoL) and overall survival (OS) in patients with head and neck cancer treated with intensity modulated radiation therapy (IMRT), conformal radiation therapy (3DCRT) or conventional radiation therapy (2DRT).

METHODS AND MATERIALS

In this real-world, multi-institutional and prospective study, HRQoL outcomes were assessed using the European Organisation for Research and Treatment of Cancer Quality-of-life Questionnaire Core 30 (EORTC QLQ-C30) and European Organisation for Research and Treatment of Cancer Quality-of-life Questionnaire Head and Neck 43 (H&N43) questionnaires. Item response theory was used to generate a global HRQoL score, based on the 71 questions from both forms. The effect of treatment modality on HRQoL was studied using multivariate regression analyses. Survival was estimated using the Kaplan-Meyer method, and groups were compared by the log-rank test.

RESULTS

Five hundred and seventy patients from 13 institutions were included. Median follow-up was 12.2 months. Concerning the radiation technique, 29.5% of the patients were treated with 2DRT, 43.7% received 3DCRT, and 26.8% were treated with IMRT. A higher proportion of patients receiving 2DRT had a treatment interruption of more than 5 days (69% vs 50.2% for 3DCRT and 42.5% for IMRT). IMRT had a statistically significant positive effect on HRQoL compared with 3DCRT (β= 2.627, standard error = 0.804, P = .001) and 2DRT had a statistically significant negative effect compared with 3DCRT (β= -5.075, standard error = 0.926, P < .001). Patients receiving 2DRT presented a worse OS (P = .01). There were no differences in OS when IMRT was compared with 3DCRT.

CONCLUSIONS

IMRT provided better HRQoL than 3DCRT, which provided better HRQoL than 2DRT. Patients receiving 2DRT presented a worse OS, which might be related to more frequent treatment interruptions.

Pluripotent Stem Cell-Derived Mesenchymal Stem Cells Show Comparable Functionality to Their Autologous Origin

A multimodal therapeutic approach involving radiotherapy is required when treating head and neck squamous cell carcinoma. However, radiotherapy is restricted due to its high risk for damages to the surrounding healthy tissue of the treated area. Tissue regeneration and wound healing is promoted by the survival and regenerative capacities of tissue-resident or invading stem cells. Mesenchymal stem cells (MSCs) exhibit a promising therapeutic potential in the field of cell-based tissue engineering and regenerative medicine due to their immunomodulatory properties and differentiation capacity. However, the generation of MSCs for therapeutic applications is still a major challenge. We aimed to produce highly homogeneous induced pluripotent stem cell-derived mesenchymal stem cells (iP-MSCs) in an autologous manner from initially isolated human mucosa mesenchymal stem cells (mMSCs) of the upper respiratory tract. Therefore, mMSCs were reprogrammed into induced pluripotent stem cells (iPSCs) by non-integrative chromosomal technologies and differentiated into corresponding iP-MSCs. We demonstrated that mMSCs and iP-MSCs show similar cell characteristics in terms of morphology, clonogenic potential, differentiation, and surface phenotype. Moreover, iP-MSCs demonstrated related immunosuppressive capacity as mMSCs including the secretion of cytokines, and T cell inhibition. Therefore, generating iP-MSCs in an autologous manner may be a novel personalized treatment option in regenerative medicine.

[Late toxicity following primary conservative treatment : Dysphagia and xerostomia]

Dysphagia and xerostomia are still among the most important acute and late side effects of radiotherapy. Technical developments over the past two decades have led to improved diagnostics and recognition as well as understanding of the causes of these side effects. Based on these findings and advances in both treatment planning and irradiation techniques, the incidence and severity of treatment-associated radiogenic late sequelae could be clearly reduced by the use of intensity-modulated radiotherapy (IMRT), which could contribute to marked long-term improvements in the quality of life in patients with head and neck cancer. Highly conformal techniques, such as proton therapy have the potential to further reduce treatment-associated side effects in head and neck oncology and are currently being prospectively tested within clinical trial protocols at several centers.

Results from a 1-day workshop on the assessment of quality of life in cancer patients: a joint initiative of the Japan Clinical Oncology Group and the European Organisation for Research and Treatment of Cancer

This report summarizes the presentations and discussion in the first Japan Clinical Oncology Group-European Organisation for Research and Treatment of Cancer Quality of Life/Patient-Reported Outcome workshop funded by the National Cancer Center Hospital that was held on Saturday, 1 September 2018 in Tokyo, Japan. The infrastructure and understanding regarding the Quality of Life/Patient-Reported Outcome assessment of cancer patients in Japan is still immature, in spite of the increased demand for oncological Patient-Reported Outcome research felt not only by researchers but also by patients or other stakeholders of cancer drug development. The workshop aimed to share each perspective, common issues to be considered and future perspectives regarding the strong alliance between the European Organisation for Research and Treatment of Cancer Quality of Life Group and the Japan Clinical Oncology Group for Quality of Life/Patient-Reported Outcome research as well as explore the possibility of conducting collaborative research. European Organisation for Research and Treatment of Cancer is a leading international cancer clinical trials organization, and its Quality of Life Group is a global leader in the implementation of Quality of Life research in cancer patients. The three invited speakers from the European Organisation for Research and Treatment of Cancer Quality of Life Group presented their perspective, latest methodology and ongoing projects. The three speakers from the Japan Clinical Oncology Group presented their current status, experience and some issues regarding data management or interpretation of the Patient-Reported Outcome data. The two patient advocates also shared their expectations in terms of advances in cancer research based on the Patient-Reported Outcome assessment. As the next steps after this workshop, the Japan Clinical Oncology Group and European Organisation for Research and Treatment of Cancer have decided to cooperate more closely to facilitate Patient-Reported Outcome research in both the groups, and the Japan Clinical Oncology Group has approved the establishment of a new committee for Quality of Life/Patient-Reported Outcome research in Japan.

A randomized pilot study on self-management in head and neck lymphedema

BACKGROUND

The purpose of this pilot trial was to determine the feasibility of a self-managed lymphedema randomized control trial to test the effectiveness of a head and neck-specific exercise protocol.

METHODS

Nine participants were randomized to receive usual treatment provided by an Australian metropolitan teaching hospital (n = 4) or usual treatment with an added head and neck exercise regime (n = 5). Feasibility was assessed through ease of recruitment, adherence, and safety. Lymphedema reduction and quality of life (QOL) data were assessed at baseline (0 week) and follow-up (6 weeks).

RESULTS

The study was feasible in terms of safety and participant retention. However, a slow recruitment rate and low adherence may impact future trials. There were no significant differences in lymphedema reduction or QOL between groups.

CONCLUSION

This pilot feasibility study demonstrated that a self-management trial can be implemented, however, modifications will be required due to the slow recruitment and poor adherence rates.

Phase III study of nivolumab alone or combined with ipilimumab as immunotherapy versus standard of care in resectable head and neck squamous cell carcinoma

Locally advanced head and neck squamous cell carcinoma (LA-HNSCC) often requires postoperative chemoradiation with high risk of toxicity. Disease-free survival (DFS) after 2 years is approximately 70%. Combining nivolumab (N), a PD-1-inhibitor and ipilimumab (I), a CTLA4- inhibitor, may improve DFS due to antitumor effects of immunotherapy. The IMSTAR-HN study compares neoadjuvant N and N ± I 6 months after adjuvant therapy versus standard therapy as first-line treatment for LA-HNSCC. Eligible patients have treatment-naive LA-HNSCC, Eastern cooperative oncology group performance score (PS) ≤1 and no distant metastasis. 276 patients will be randomized into two arms. Primary endpoint is DFS and secondary endpoint includes locoregional control (LRC) and overall survival (OS). This study is one of the first in HNSCCs implementing immunotherapy in first-line treatment in a curative setting. Clinical Trial Registration: NCT03700905 (ClinicalTrials.gov).

Hospital Based Quality of Life in Oral Cancer Surgery

The diagnosis of cancer and its treatment have an incomparable impact on a patient's life. In the early postoperative stages after the surgical treatment of oral squamous cell carcinoma (OSCC), functions and well-being are limited, which leads to a fundamental decline of the quality of life (QoL). To date, no studies have been performed that focus on the development of special aspects during the time of the in-patient stay of OSCC patients. With the results of this cross-sectional study, we are able to identify those patients who tend to require special support. This cross-sectional study determined the postoperative QoL with a questionnaire (QU) that was handed out twice to OSCC patients after surgery during their inpatient stay. The questions were based on the European Organisation for Research and Treatment of Cancer (EORTC)'s Quality of Life Questionnaire (QLQ)-C30 and QLQ-H&N35. In our study, we found that for postoperative OSCC patients, eating, swallowing and speech were influenced the most. After decannulation, tracheotomy showed no impact on functions. Social contact was impaired at both timepoints. Especially female patients consider themselves to be more impaired on the scale of social contact. QoL should be checked with a standardized QU as an established tool during hospitalization in every oncology department. Only this procedure can pinpoint those patients who have struggles with their surgical outcome and need more assistance.

Psychometric evaluation of Azeri version of the head and neck cancer specific quality of life questionnaire (EORTC QLQ-H&N43)

BACKGROUND

Oral cancer surgery can have a deep effect on the quality of life in the patient both in terms of functional and psychological aspects. This study aimed to translate and validate the European Organization for Research and Treatment of Cancer head and neck cancer specific quality of life questionnaire (EORTC QLQ-H&N43) in Azerbaijan.

METHODS

Forward-backward translation was applied in order to translate the EORTC QLQ-H&N43 from English into Azeri. Then, a sample of patients with oral cancer attending a teaching hospital affiliated to Azerbaijan Medical University completed the EORTC QLQ-C30 (the core cancer specific questionnaire), and the EORTC QLQ-H&N43. To evaluate psychometric properties of the QLQ-H&N43, known groups validity, convergent and divergent validity was performed. Internal consistency reliability was examined by estimating the Crornbach's alpha coefficient.

RESULTS

Ninety-six patients with confirmed diagnosis of oral cancer were entered into the study. The mean age of patients was 59.6 (SD = 10.7) years and 36 patients (37.5%) diagnosed as having stage IV and 10 patients (10.5%) were metastatic. The results obtained from comparing quality of life scores among these patients showed that the questionnaire was able to differentiate among patients who differed in stage and metastasis lending support to its validity. In addition convergent and divergent validity showed satisfactory results. The internal consistency of the multi-item scales as assessed by the Cronbach's alpha coefficient showed acceptable results (alpha ranging from 0.66 to 0.78).

CONCLUSION

The findings suggest that in general the Azeri version of EORTC QLQ-H&N43 has satisfactory internal consistency reliability and validity, but additional psychometric evaluation is needed to draw firm conclusions.

Quality of life in patients with oral cancer treated by different reconstruction methods as measured by the EORTC QLQ-H&N43

This was a prospective clinical study and the purpose was to assess the quality of life (QoL) as the primary endpoint for patients given prospective treatment for cancer of the oral cavity that required reconstruction using various reconstruction methods in Azerbaijan. All patients who were operated on during the year 2017 to 2018 were entered into the study. Quality of life was assessed six months postoperatively using the European Organization for Research and Cancer Treatment Core Cancer Quality of Life (EORTC QLQ-C30) and the Head and Neck Specific Quality of Life (QLQ-H&NN43) questionnaires. A total of 96 patients completed the questionnaires. There were 36 patients who did not receive a flap, 31 patients received a local flap, and 29 patients had distant-regional flaps. QoL assessed by the EORTC QLQ-C30, and the QLQ-H&N43 was lower in patients who received a local flap. In general, the results showed that the reconstruction with a distant-regional flap compared with no flap and local flap leads to improved quality of life of patients with oral cancer.

Increased Pain Reporting by Head and Neck Cancer Patients at Radiation Oncology Consultation: A Quality-of-Life Analysis

OBJECTIVES

Head and neck cancers (HNC) are associated with significant morbidity. Quality-of-life (QoL) analyses can assist with understanding subjective factors shaping the patient experience. Here, we assess for patient and/or tumor factors associated with increased pain reporting at the time of initial radiation oncology consultation at a single institution in 2015.

STUDY DESIGN

Prospective cross-sectional questionnaire research.

METHODS

All new patient consultations in 2015 were offered the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core-30 (EORTC QLQ-C30) survey. HNC patients were also offered the EORTC QLQ-HN35 module. Retrospective chart review was performed on patients who completed the surveys. Patient demographics, tumor characteristics, and QoL responses were analyzed for potential associations. Statistical analyses were conducted using SAS v9.4 (SAS Institute, Cary, NC), with P < .05 considered significant.

RESULTS

Of 771 new patient consultations, 137 consultations were for HNC patients. Of those, 62 patients completed both surveys. HNC patients reported greater pain relative to all other disease sites (odds ratio [OR]: 2.05; P < .01). On univariate analysis of the EORTC QLQ-C30 data, increased pain was found to be associated with tumor size > 4 cm (OR: 3.05; P ≤ .05). The EORTC QLQ-HN35 data revealed lymph node involvement to be independently associated with pain (OR: 3.12; P ≤ .05). On multivariate analysis, increased pain was associated with lack of pain medication prescription at the time of consultation (P ≤ .05) and age ≥ 65 years (P ≤ .05).

CONCLUSION

Patients with HNC reported significantly more pain at consultation than patients with other primary malignancies. Understanding factors contributing to subjective pain may allow providers to potentially address these symptoms proactively to improve patients' QoL.

Feasibility and Effects of a Supervised Exercise Program Suitable for Independent Training at Home on Physical Function and Quality of Life in Head and Neck Cancer Patients: A Pilot Study

Introduction: Head and neck cancer patients often suffer from physical and cognitive impairments after cancer treatment. During rehabilitation, exercise therapy can improve physical function and quality of life (QoL). Surveys demonstrated patients' preference for home training with low- to moderate-intensity. This study was conducted in order to develope a suitable home-based training program. Therefore, the feasibility and effects of a low- to moderate-intensity exercise intervention on physical functions and QoL were evaluated. Methods: Training was conducted as supervised group training and consisted of mobilization, coordination, resistance, stretching, and relaxation exercises. The intervention lasted 12 weeks with 2 training sessions per week. Feasibility, attendance rate, physical function (eg, range of motion, 6-minute walk test [6MWT]), and QoL (eg, EORTC QLQ-30) were analyzed. Results: Ten out of 12 participants completed the intervention (83%) with an average attendance rate of 83%. Participants showed significant improvements in selected physical functions. For example, head rotation increased by 11.2° (P = .042), walking distance in the 6MWT increased by an average of 43.3 m (P = .010), and the global QoL scale improved by 8.2 points (P = .059). Additionally, there were positive changes in the physical function scale (P = .008), cognitive function scale (P = .015), and social function scale (P = .031) of the EORTC QLQ-30. Conclusion: Data indicate that the exercise program was feasible and had positive effects on physical function and QoL. Future research will analyze the effects of a home-based exercise program on physical function and QoL in a large-scale study.

Long-term quality of life after surgery of head and neck cancer with microvascular reconstruction: a prospective study with 4.9-years follow-up

Purpose

The aim of this study was to evaluate the long-term health-related quality of life (HRQoL) of head and neck cancer patients with microvascular surgery. Surgical treatment causes great changes in patient HRQoL. Studies focusing on long-term HRQoL after microvascular reconstruction for head and neck cancer patients are scarce.

Methods

We conducted a prospective study of 93 patients with head and neck cancer and microvascular reconstruction in Helsinki University Hospital Finland. HRQoL was measured using the 15D instrument at baseline and after a mean 4.9-years follow up. Results were compared with those of an age-standardized general population.

Results

Of the 93 patients, 61 (66%) were alive after follow-up; of these, 42 (69%) answered the follow-up questionnaire. The median time between surgery and HRQoL assessment was 4.9 years (range 3.7–7.8 years). The mean 15D score of all patients (n = 42) at the 4.9-years follow up was statistically significantly (p = 0.010) and clinically importantly lower than at baseline. The dimensions of “speech” and “usual activities” were significantly impaired at the end of follow up. There was a significant difference at the 4.9-years follow-up in the mean 15D score between patients and the general population (p = 0.014). After follow up, patients were significantly (p < 0.05) worse off on the dimensions of “speech,” “eating,” and “usual activities.”

Conclusions

Long-term HRQoL was significantly reduced in the whole patient cohort. Speech and usual activities were the most affected dimensions in head and neck cancer patients with microvascular reconstruction at the end of the 4.9-years follow up.

Evaluation of quality of life in patients with oral cancer after mandibular resection: Comparing no reconstruction, reconstruction with plate, and reconstruction with flap

This cross-sectional study aimed to assess and compare quality of life in patients with advanced oral cavity tumors after mandibular resection in 3 groups (no reconstruction, reconstruction with plate, and reconstruction with flap) at the Cancer Institute, affiliated to Tehran University of Medical Sciences. Quality of life was measured using the European Organization for Research and Treatment of Cancer core quality of life questionnaire and European Organization for Research and Treatment of Cancer head and neck cancer-specific quality of life questionnaire-35 items. The comparison was tested using Kurskal-Wallis analysis. All 120 patients were entered into the study. The mean age of patients was 48.5 (standard deviation = 18.1) years. Patients presented with advanced stage of the disease and underwent mandibular resection with no reconstruction (n = 40), reconstruction with plate (n = 41), and reconstruction with flap (n = 39). The findings showed that in general, there were no statistically significant differences in quality of life among 3 groups except for speech problem (P = .4), dry mouth (P = .03), and feeling ill (P = .04). Although there were no significant differences in quality of life among patients in 3 groups, overall patients who received reconstruction with flap reported better functioning and fewer symptoms. Those who did not receive any reconstruction reported the worse conditions.

The Statistical Evaluation of Treatment and Outcomes in Head and Neck Squamous Cell Carcinoma Clinical Trials

The purpose of this article is two-fold: to help statisticians confronted with the design, implementation and analysis of clinical trials and new to the field of head and neck cancer; but also to sensitize research physicians with the role, the tasks and the challenges faced by the medical statisticians. These two purposes altogether will hopefully encourage and enable fluid communication between the research physician and the medical statistician and the understanding of each other's field and concerns. In particular, the methodological challenges resulting from the heterogeneity of the head and neck cancer, the complexity of the treatments and the associated comorbidities are presented with examples borrowed from medical literature and from the practical experience of the authors in this field.

Listening to the voice of patients with head and neck cancer: A systematic review and meta-synthesis

The aim was to conduct a systematic review and a meta-synthesis of primary qualitative studies exploring experiences of head and neck cancer patients (HNC) undergoing radio and/or chemotherapy, in order to provide a better understanding of this phenomenon and supply new directions for care and clinical practice. Six databases were systematically searched, and 13 studies were included. The meta-synthesis methodology was adopted to conceptualise the way in which patients lived their cancer journey and the impact of treatments on their daily life. Four themes embracing various aspects of HNC patients' experiences were identified: (a) self-body image and perceived quality of life; (b) experiences and treatment of symptoms; (c) cancer journey; and (d) the relationship with health professionals. The finding demonstrates the importance of acknowledging that treatment sequelae and patients' daily issues do not appear, develop and affect people's lives in isolation and should be considered and analysed as a whole within the social and cultural context of patients' lives. Further research is needed to explore the treatment experience of HNC patients throughout their cancer journey with a more holistic approach that involves health professionals, caregivers and other family members and peers in the community.

Radiation-induced sensitivity of tissue-resident mesenchymal stem cells in the head and neck region

BACKGROUND

Tissue-resident mesenchymal stem cells (MSCs) possess the ability to migrate to areas of inflammation and promote the regeneration of damaged tissue. However, it remains unclear how radiation influences this capacity of MSC in the head and neck region.

METHODS

Two types of MSCs of the head and neck region (mucosa [mMSC] and parotid gland [pMSC]) were isolated, cultured and exposed to single radiation dosages of 2 Gy/day up to 10 days. Effects on morphology, colony forming ability, apoptosis, chemokine receptor expression, cytokine secretion, and cell migration were analyzed.

RESULTS

Although MSC preserved MSC-specific regenerative abilities and immunomodulatory properties following irradiation in our in vitro model, we found a deleterious impact on colony forming ability, especially in pMSC.

CONCLUSIONS

MSC exhibited robustness and activation upon radiation for the support of tissue regeneration, but lost their potential to replicate, thus possibly leading to depletion of the local MSC-pool after irradiation.
