Dysphagia, Speech, Voice, and Trismus following Radiotherapy and/or Chemotherapy in Patients with Head and Neck Carcinoma: Review of the Literature

Surgical and functional outcomes after salvage oropharyngectomy

OBJECTIVES

Salvage oropharyngeal surgery with free-flap reconstruction after failed radiation therapy (RT) presents unique challenges and complications. The aim of this retrospective review is to examine surgical complications and functional outcomes in patients who received salvage surgery for recurrent or persistent oropharyngeal cancer following RT.

PATIENTS AND METHODS

Patients diagnosed with oropharyngeal cancer and underwent salvage oropharyngectomy at the University of Florida between 2016-2021 were identified from inpatient and outpatient records of the Head and Neck Oncology Team. Outcomes measured were tracheostomy dependence, tube-feed dependence, and intact oral intake status. Survival outcomes using Kaplan-Meier product limit method were calculated.

RESULTS AND CONCLUSION

Twenty-six patients were included in the analysis. Average age was 63.7 years. Fourteen (53.8 %) oropharyngectomies used a transmandibular approach, ten (38.5 %) through a combined transoral and transcervical approach, and two (7.7 %) through a transcervical approach. Average time to tracheostomy decannulation was 25.1 days. At 6 months, twenty (83.3 %) patients were gastric tube independent with twelve (54.2 %) patients tolerating any oral intake. At 12 months, gastric tube independent feeds decreased to nine (60 %) patients with thirteen (92.9 %) patients tolerating oral intake. The median overall survival was 27 months with local cancer recurrence being the most common cause of death. Patients undergoing salvage oropharyngectomy for recurrent disease continue to face prolonged tracheostomy and tube dependent feedings. Despite intact swallowing function, patients preferred to use gastric tube feedings, likely for speed, ease, and convenience. Further studies are needed to analyze factors influencing these conflicting functional outcomes and predictive factors impacting survival.

Oropharyngeal Geometry of Maxilectomized Patients Rehabilitated with Palatal Obturators in the Trans-surgical Period: Repercussions on the Voice

INTRODUCTION

Patients undergoing maxillectomies may present alterations in the stomatognathic functions involved in oral communication. Rehabilitative treatment should favor the rescue of these functions, through surgical flaps, obturator prostheses or both.

OBJECTIVES

The present study aims to present the impact of the use of the palatal obturator on the oropharyngeal geometry and on the voice of patients undergoing maxillectomies, after adaptation to trans-surgical palatine obturators (TPO).

METHODS

Twelve patients treated at a Cancer Hospital, submitted to maxillectomy and rehabilitated during surgery were evaluated. The oropharyngeal geometry was measured by acoustic pharyngometry and the vocal parameters were evaluated through auditory-perceptual and acoustic analyses. The comparison between the results with and without TPO was analyzed using the Wilcoxon test and the correlation between oropharyngeal measurements and acoustic parameters using Spearman's correlation coefficient, all with a significance level of 5%.

RESULTS

There was a decrease in the following oropharyngeal measurements with the use of TPO: length of the pharyngeal cavity and vocal tract, volume of the oral cavity, pharyngeal and vocal tract and area of ​​the oropharyngeal junction. There was no difference in the length of the oral cavity and in the glottic area between situations with and without TPO. In the vocal evaluation, changes in intelligibility and resonance were observed in the situation without TPO and, in only one case, mild hypernasality was detected in the situation with TPO.

CONCLUSIONS

It is concluded that the use of TPO brought the oropharyngeal measurements closer to normal values ​​and provided an improvement in speech intelligibility and vocal resonance in maxilectomized individuals.

Oral and Pharyngeal Dysphagia in Adults

Patients with oral and pharyngeal dysphagia have difficulty forming a cohesive bolus and/or transferring food from the mouth into the pharynx and esophagus to initiate the involuntary swallowing process. This may be accompanied by nasopharyngeal regurgitation, aspiration, and a sensation of residual food remaining in the pharynx. Abnormalities affecting the upper esophageal sphincter, pharynx, larynx, or tongue, in isolation or combination, result in oropharyngeal dysphagia affecting either or both transit and airway protection. These issues can be addressed with a combination of management of the underlying systemic disease, with surgical intervention or with swallow therapy.

Eating and speech problems in oral and pharyngeal cancer survivors - Associations with treatment-related side-effects and time since diagnosis

AIMS

The aim of this cross-sectional study was to find factors associated with problems with the ability to eat and speak in oral and pharyngeal cancer (OPC) survivors and to evaluate if the panorama of oral problems varied with time since diagnosis.

METHODS AND RESULTS

A questionnaire assessing cancer diagnosis and treatment, oral health-related quality of life, and presence of treatment-related side-effects was sent to members of the Norwegian Head and Neck Cancer Association. Three-quarters (n = 117) of the respondents experienced xerostomia, and 51% (n = 79) had dysphagia. Prevalence of dysphagia, trismus, and dysphonia was lowest among respondents diagnosed within the last 5-10 years prior to the study. Eating problems were reported by 75% (n = 121) of the OPC survivors and were associated with xerostomia, dysphagia, trismus, having removed part of the tongue, cancer diagnosis within 5 years prior to the study and having little problems with caries and tooth fracture. Speaking problems were experienced by 60% (n = 93) of the OPC survivors, and were associated with dysphonia, dysphagia, and trismus.

CONCLUSION

Our study shows a high prevalence of oral problems among OPC survivors and points to targets for interventions for eating and speech impairments that may improve oral health-related quality of life.

The Change in Social Eating over Time in People with Head and Neck Cancer Treated with Primary (Chemo)Radiotherapy: The Role of Swallowing, Oral Function, and Nutritional Status

This study aimed at investigating the change in social eating problems from diagnosis to 24 months after primary (chemo)radiotherapy and its associations with swallowing, oral function, and nutritional status, in addition to the clinical, personal, physical, psychological, social, and lifestyle dimensions. Adult patients from the NETherlands QUality of life and BIomedical Cohort (NET-QUBIC) treated with curative intent with primary (chemo)radiotherapy for newly-diagnosed HNC and who provided baseline social eating data were included. Social eating problems were measured at baseline and at 3-, 6-, 12-, and 24-month follow-up, with hypothesized associated variables at baseline and at 6 months. Associations were analyzed through linear mixed models. Included patients were 361 (male: 281 (77.8%), age: mean = 63.3, SD = 8.6). Social eating problems increased at the 3-month follow-up and decreased up to 24 months (F = 33.134, p < 0.001). The baseline-to-24 month change in social eating problems was associated with baseline swallowing-related quality of life (F = 9.906, p < 0.001) and symptoms (F = 4.173, p = 0.002), nutritional status (F = 4.692, p = 0.001), tumor site (F = 2.724, p = 0.001), age (F = 3.627, p = 0.006), and depressive symptoms (F = 5.914, p < 0.001). The 6-24-month change in social eating problems was associated with a 6-month nutritional status (F = 6.089, p = 0.002), age (F = 5.727, p = 0.004), muscle strength (F = 5.218, p = 0.006), and hearing problems (F = 5.155, p = 0.006). Results suggest monitoring social eating problems until 12-month follow-up and basing interventions on patients' features.

Voice Outcomes Following Head-Lift Exercises in Head and Neck Cancer: A Randomized Controlled Study

OBJECTIVES

This prospective randomized study aimed to investigate whether patients with dysphagia after treatment for head and neck cancer improve their vocal function from doing head lift exercises (Shaker's exercise).

METHODS

Patients were randomized into an intervention group (n = 24) or a control group (n = 26). Patients in the intervention group performed the head lift exercise three times a day for 8 weeks. At baseline and at follow-up after 8 weeks, participants' voices were evaluated perceptually with the Grade-Roughness-Breathiness-Asthenia-Strain (GRBAS) scale. Vocal fry (VF) was also perceptually evaluated and patients filled in the Voice Handicap Index (VHI).

RESULTS

Patients in the intervention group were perceptually evaluated as having less roughness and vocal fry in their voices at follow-up compared to the control group. There were no statistically significant changes between baseline and follow-up neither in the intervention nor the control group regarding GRBAS, VF, or VHI. Neither were there any statistically significant differences within the groups when results on the perceptual evaluations at baseline and follow-up were compared.

CONCLUSIONS

The voices of the participants in the intervention group were slightly better than the voices of the participants in the control group with less roughness and VF at follow-up. However, no improvement in the VHI or the remaining GRBAS variables was found. Therefore, this study can only give cautious support to the head lift exercise as a method for improving the voice of patients with dysphagia after treatment for head and neck cancer.

The Antioxidant Activity and Induction of Apoptotic Cell Death by Musa paradisiaca and Trigona sp. Honey Jelly in ORL115 and ORL188 Cells

Background

Head and neck cancer patients usually need nutritional support due to difficulties in swallowing and chewing. Therefore, this study aimed to formulate Musa paradisiaca and Trigona sp. honey jelly (MTJ) as a convenient functional food.

Methods

The antioxidant properties were analysed using 2,2'-diphenyl-1 picrylhydrazyl (DPPH), ferric reducing antioxidant potential (FRAP) and 2,2'-azinodi 3-ethylbenthiazolinesulfonate (ABTS) assays. Cytotoxicity was assayed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) test and the induction of apoptosis was observed via caspase-3/7 activity assay. The identification of phenolic compounds was done via ultra-high-performance-liquid chromatography coupled to mass spectrometer (UHPLC-MS/MS).

Results

The antioxidant analysis exhibited: the half inhibitory concentration (IC₅₀) of DPPH inhibition, 54.10 (SD = 4.51) μg/mL; the FRAP value, 30.07 (SD = 0.93) mM TEQ/100 g; and the ABTS value, 131.79 (SD = 8.73) mg TEQ/100 g. Cinnamic acid was the most abundant phenolic compound, followed by maleic acid and salicylic acid. The IC₅₀ for ORL115 and ORL188 were 35.51 mg/mL and 43.54 mg/mL, respectively. The cells became rounded and dissymmetrical which reduced in number and size. The apoptotic cell death in ORL115 and ORL188 was deduced as caspase-3/7 activities that significantly increased (P < 0.05).

Conclusion

The study evidenced that the antioxidant activity of MTJ could influence the induction of apoptosis in ORL115 and ORL188 in future investigations and verifications.

Investigation of the Effect of Radiotherapy Dose on Chewing and Swallowing Structures in Head and Neck Cancer Patients Treated with Concomitant Chemoradiotherapy

Intensity-modulated radiotherapy (IMRT) is a treatment method that is used in the treatment of head and neck cancers. Impairment of chewing and swallowing functions in the early and late periods of radiotherapy is frequent. Therefore, revealing the dose-effect relationship is important. The main purpose of this study is to investigate the dose-effect relationship between chewing and swallowing structures objectively via a standardized videofluoroscopy protocol. The study included 35 participants treated with chemo-IMRT. A videofluoroscopic swallowing study (VFSS) was performed before IMRT, and 3 and 6 months after IMRT. VFSS results were scored according to the Modified Barium Swallow Impairment Profile (MBSImP) and the Penetration-Aspiration Scale (PAS). Maximum interincisor mouth opening, body mass index (BMI), and Functional Oral Intake Scale levels were determined in these cases. The quality of life of participants was evaluated. There was a significant increase in PAS and MBSImP scores and a significant decrease in BMI scores of the patients after treatment. Xerotomy and sticky saliva complaints increased after treatment. The dose to the mastication muscles (> 40 Gy) and the temporomandibular joint (> 46 Gy) were found to be associated with a decrease in BMI; the dose to the superior pharyngeal constructor muscle (> 58 Gy) was found to be associated with pharyngeal stripping wave. The presence of aspiration was associated with the inferior pharyngeal constructor muscle, glottic larynx, supraglottic larynx, and upper esophageal sphincter. Important findings to emerge from this study include detected toxic dose limits. These findings may guide physicians to minimize the side effects of IMRT.

Silenced: Patients' experiences of voicelessness in head and neck cancer

OBJECTIVES

The objective of this qualitative study was to explore patients' experiences of communicating with health professionals following a diagnosis of head and neck cancer (HNC).

METHODS

A qualitative research approach based on social constructionist theory was used. A total of 21 in-depth semi-structured interviews were conducted with people diagnosed with HNC. Thematic analysis was used to identify themes.

RESULTS

The experience of losing the capacity for speech was experienced by survivors of HNC as distressing and traumatic. Voicelessness was not just a loss of physical speech, but a holistic experience of silencing. A number of tensions emerged including patients' experiences of losing their voice and then finding different ways to verbally express themselves; in interactions with health professionals there was a tension between abrupt, hurried communication and a slower, more mindful communication style. Sub-themes around communication style emerged where disparities between levels of health literacy were unaddressed, and patients' experienced a lack of empathy. Another tension experienced was between an old style medical model and the ideal of person-centred care and the biopsychosocial model of health.

CONCLUSION

Whether HNC patients lose their voice temporarily, have periods of voicelessness, or are able to speak, but feel unheard, the treatment experience is too often one of disempowerment and silencing of their perspectives.

PRACTICE IMPLICATIONS

Health professionals are challenged to find creative communication methods, to practice mindful listening, source speech pathology and adaptive technologies, and to facilitate communication that supports patients in expressing their values, preferences and needs.

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.

Long-term cognitive, psychosocial, and neurovascular complications of unilateral head and neck irradiation in young to middle-aged adults

Background

With a growing, younger population of head and neck cancer survivors, attention to long-term side-effects of prior, often radiotherapeutic, treatment is warranted. Therefore, we studied the long-term cognitive effects in young adult patients irradiated for head and neck neoplasms (HNN).

Methods

Young to middle-aged adults with HNN (aged 18-40 years) and treated with unilateral neck irradiation ≥ 5 years before inclusion underwent cardiovascular risk and neuropsychological assessments and answered validated questionnaires regarding subjective cognitive complaints, fatigue, depression, quality of life, and cancer-specific distress. Additionally, magnetic resonance imaging (MRI) of the brain was performed to assess white matter hyperintensities (WMH), infarctions, and atrophy.

Results

Twenty-nine patients (aged 24–61, 13 men) median 9.2 [7.3–12.9] years post-treatment were included. HNN patients performed worse in episodic memory (Z-score = -1.16 [-1.58–0.34], p < 0.001) and reported more fatigue symptoms (Z-score = 1.75 [1.21–2.00], p < 0.001) compared to normative data. Furthermore, patients had a high level of fear of tumor recurrence (13 patients [44.8%]) and a heightened speech handicap index (13 patients [44.8%]). Only a small number of neurovascular lesions were found (3 infarctions in 2 patients and 0.11 [0.00–0.40] mL WMH), unrelated to the irradiated side. Cognitive impairment was not associated with WMH, brain atrophy, fatigue, or subjective speech problems.

Conclusions

HNN patients showed impairments in episodic memory and an increased level of fatigue ≥ 5 years after radiotherapy compared to normative data. Cognitive impairments could not be explained by WMH or brain atrophy on brain MRI or psychological factors.

The effect of the Shaker head‐lift exercise on swallowing function following treatment for head and neck cancer: Results from a randomized, controlled trial with videofluoroscopic evaluation

Background

Dysphagia is common following treatment for head and neck cancer (HNC) and intervention to improve swallowing function is warranted. This study aimed to evaluate the efficacy of the Shaker head‐lift exercise (HLE) to improve dysphagia in HNC patients.

Methods

Patients treated for HNC with radiochemotherapy and with subsequent dysphagia were randomly assigned to intervention (HLE, n = 25) and control (standard dysphagia management, n = 27) groups. Videofluoroscopic evaluation of penetration‐aspiration, initiation, residue, movement of selected structures, and self‐perceived swallowing function, before and after 8 weeks of treatment, were compared.

Results

Although adherence to training was high, no statistically significant differences in objectively measured swallowing function between the groups or within‐group changes were found. Self‐perceived swallowing function improved in the intervention group.

Conclusions

In this HNC population, neither HLE nor standard dysphagia management improved objectively measured swallowing function as evaluated after 8 weeks. Future research focusing on finding effective interventions for dysphagia is warranted.

Early-Stage Glottic Squamous Cell Carcinoma in the Era of Image-Guided Radiotherapy

Early-stage squamous cell cancer (SCC) of the glottis has a good prognosis. Therefore, patients have long survival outcomes and may potentially suffer from late toxicities of radiotherapy. Radiotherapy with a conventional parallel-opposed-pair or anterior-oblique beam arrangements for stage 1 and 2 glottic SCC have field borders that traditionally cover the entire larynx, exposing organs-at-risk (e.g. carotid arteries, contralateral vocal cord, contralateral arytenoid and inferior pharyngeal constrictor muscles) to high radiation doses. The potential long-term risk of cerebrovascular events has attracted much attention to the dose that carotid arteries receive. Swallow and respiratory motion of laryngeal structures has been an important factor that previously limited reduction of the radiation treatment volume. Motion has been evaluated using multiple imaging modalities and this information has been used to calculate PTV margins for generation of more limited target volumes. This review discusses the current literature surrounding dose-effect relationships for various organs-at-risk and the late toxicities that are associated with them. This article also reviews the currently available data and effects of laryngeal motions on dosimetry to the primary target. We also review the current limitations and benefits of a more targeted approach of radiotherapy for early-stage glottic SCCs and the evolution of CT-based IGRT and MR-guided radiotherapy techniques that may facilitate a shift away from a conventional 3D-conformal radiotherapy approach.

Postoperative quality of life and therapy-related impairments of oral cancer in relation to time-distance since treatment

PURPOSE

Oral cancer resection can cause physical and psychological impairments that influence the quality of life (QoL). Depending on the postoperative time-distance, the occurrence and intensity of these impairments may change. We evaluated the sequelae and changes in therapy-related impairments during the postoperative course to detect associations between the time since surgery and the presence of disorders.

METHODS

Data from a questionnaire completed by 1359 patients who underwent surgical treatment of oral squamous cell carcinoma and were involved in a multicenter rehabilitation study of the German-Austrian-Swiss Cooperative Group on Tumors of the Maxillofacial Region (DÖSAK) that included 43 oral and maxillofacial clinics in Germany, Austria, and Switzerland were retrospectively analyzed.

RESULTS

Physical impairments, including those in appearance, mouth opening ability, ability to smell, gastric disorders, mandible mobility, breathing, and shoulder/arm mobility, were significantly associated with and increased with time-distance since surgery. Esthetic appearance most strongly correlated with the highest perception of worsening. Regarding psychological disorders, worry about tumor recurrence, depression, and worse prospects were significantly associated. Among the postoperative sequelae, fear of tumor recurrence decreased continuously; however, depression and worse prospects increased. The general QoL did not significantly differ overall during the postoperative course.

CONCLUSIONS

Therapy-related impairments change during the postoperative course based on the time-distance since surgery. The general QoL may not markedly vary; however, single impairments, to some extent, can increase or decrease.

IMPLICATIONS FOR CANCER SURVIVORS

Continuous adaptation of supportive cancer therapy is required during follow-up to sufficiently address individual treatment needs.

Validity and Reliability of an Arabic Version of MD Anderson Dysphagia Inventory (MDADI)

Dysphagia is a common adverse event among head and neck (H&N) cancer patients. We aimed, for the first time, to validate the Arabic version of the MD Anderson Dysphagia Inventory (MDADI) among 82 Saudi Arabian patients with H&N cancer. We followed established validation guidelines and translated the 20-item MDADI using the forward-backward method. Our results revealed 100% feasibility. Test-retest reliability demonstrated acceptable interclass correlation coefficients (ICC) for the subscale domains (emotional = 0.973, physical = 0.971, and functional = 0.956) and composite score (ICC = 0.984). The Cronbach's alpha coefficients for the emotional, functional, and physical subscales were 0.937, 0.825, and 0.945, respectively (composite score = 0.975). We confirmed concurrent validity by demonstrating significant correlations between the domains of the Arabic MDADI and European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Head and Neck Module (QLQ-H&N35). Our study validated the Arabic version of the MDADI among H&N cancer patients from Saudi Arabia.

[Post-operative prevalence of dysphagia in head-and-neck cancer patients in the acute care units]

OBJECTIVE

 Dysphagia constitutes a frequent post-operative functional impairment in head-and-neck cancer patients. This impairment can result in aspiration/penetration and limitations of oral intake. Therefore, often it requires a therapeutic intervention. In this study, prevalence of post-operative dysphagia and its associations with the tumour stage, localisation, patients' age, and biological sex were analysed for the inpatient treatment setting.

MATERIAL AND METHODS

 A total of 201 adult head-and-neck cancer patients (mean age 63 years) were analysed prospectively by FEES in two university hospitals in regard to their penetration/aspiration, limitations of oral intake, and need for therapeutic interventions directly after the operative tumour treatment. Additionally, the influence of the same patients' characteristics on these three parameters were analysed by means of univariate and multivariate statistical methods.

RESULTS

 Out of 201 patients, 66.7 % needed a therapeutic intervention because of their dysphagia, 57.2 % needed a nasogastral or PEG tube due to limitations of oral intake, 45.3 % had an aspiration. In the latter subgroup, 38.5 % had a silent aspiration. Higher tumour stage, patients' higher age and male sex were shown to be significant influence factors for dysphagia, tumour localisation showed only a marginally significant result.

CONCLUSIONS

 The study demonstrated a clinical importance and relevance of the consequent and systematic treatment of post-operative dysphagia in head-and-neck cancer patients in the acute care units as a constituent of a modern oncological therapy.

Validation of Hearing Loss Prediction Tool for Cisplatin Chemotherapy and Radiation in Head and Neck Cancer Treatment

Importance

Hearing loss affects up to 88% of patients undergoing head and neck cancer treatment; however, there are few validated models to predict this outcome. A predictive posttreatment model for hearing loss will allow clinicians and patients to make well-informed decisions about treatment with cisplatin-based chemotherapies and radiotherapy.

Objective

To validate a previously created predictive model for objective hearing outcomes and to assess barriers to using the prediction nomogram in general practice for patients newly diagnosed with head and neck cancer.

Design, Setting, and Participants

This cohort study includes an evaluation of 105 patients (208 ears) and interviews with 6 clinicians. The patients were treated at a high-volume tertiary care hospital. Patient participants were newly diagnosed with head and neck cancer and treated at Siteman Cancer Center from July 1, 2018, to December 31, 2019, with radiotherapy both with and without cisplatin-based chemotherapy. Additionally, the clinicians involved in the care of patients with head and neck cancer were interviewed to assess implementation strategies.

Exposures

Radiotherapy with and without cisplatin-based chemotherapy.

Main Outcomes and Measures

Hearing defined by the audiometric pure-tone average of 1, 2, and 4 kHz.

Results

A total of 105 patients (208 ears; mean [SD] age, 61 [11] years; 82 men [78%]) were compared with the development cohort to assess the similarities and differences in case mix. All patients underwent radiation therapy, 50 (48%) received cisplatin-based chemotherapy, and 67 (64%) had a surgical resection. The mean (SD) cochlear dose of radiation was 13 (12) Gy, and the mean (SD) total cisplatin dose was 238 (83) mg/m2 for those undergoing cisplatin therapy. A calibration curve demonstrated that predicted and observed posttreatment pure-tone average were not significantly different. The model predicted a posttreatment pure-tone average greater than 35 dB (a common threshold for hearing aid consideration) with a sensitivity of 73% and specificity of 67% with an area under the curve of 0.71, showing good discrimination. Clinician interviews suggest the nomogram requires careful integration into patient counseling to clarify risks and benefits for treatment.

Conclusions and Relevance

The findings of this cohort study confirm this model's ability to predict posttreatment hearing outcomes in a unique population of patients. This model has the potential to inform pretreatment counseling and posttreatment hearing evaluations for this patient population.

Radiation-induced neuropathies in head and neck cancer: prevention and treatment modalities

Head and neck cancer (HNC) is the sixth most common human malignancy with a global incidence of 650,000 cases per year. Radiotherapy (RT) is commonly used as an effective therapy to treat tumours as a definitive or adjuvant treatment. Despite the substantial advances in RT contouring and dosage delivery, patients suffer from various radiation-induced complications, among which are toxicities to the nervous tissues in the head and neck area. Radiation-mediated neuropathies manifest as a result of increased oxidative stress-mediated apoptosis, neuroinflammation and altered cellular function in the nervous tissues. Eventually, molecular damage results in the formation of fibrotic tissues leading to susceptible loss of function of numerous neuronal substructures. Neuropathic sequelae following irradiation in the head and neck area include sensorineural hearing loss, alterations in taste and smell functions along with brachial plexopathy, and cranial nerves palsies. Numerous management options are available to relieve radiation-associated neurotoxicities notwithstanding treatment alternatives that remain restricted with limited benefits. In the scope of this review, we discuss the use of variable management and therapeutic modalities to palliate common radiation-induced neuropathies in head and neck cancers.

MRI- and CT-determined changes of dysphagia / aspiration-related structures (DARS) during and after radiotherapy

Purpose

The concept of dysphagia/aspiration-related structures (DARS) was developed against the background of severe late side effects of radiotherapy (RT) for head and neck cancer (HNC). DARS can be delineated on CT scans, but with a better morphological discrimination on magnetic resonance imaging (MRI). Swallowing function was analyzed by use of patient charts and prospective investigations and questionnaires.

Method

Seventeen HNC patients treated with intensity-modulated radiotherapy (IMRT) ± chemotherapy between 5/2012 – 8/2015 were included. Planning CT (computed tomography) scans and MRIs (magnetic resonance imaging) prior, during 40 Gray (Gy) radiotherapy and posttreatment were available and co-registered to delineate DARS. The RT dose of each DARS was calculated. Five patients were investigated posttreatment for swallowing function and assessed by means of various questionnaires for quality of life (QoL), swallowing, and voice function.

Results

By retrospective comparison of DARS volume, a significant change in four of eight DARS was detected over time. Three increased and one diminished. The risk of posttreatment dysphagia rose by every 1Gy above the mean dose (D mean) of RT to DARS. 7.5 was the risk factor for dysphagia in the first 6 months, reducing to 4.7 for months 6-12 posttreatment. For all five patients of the prospective part of swallowing investigations, a function disturbance was detected. These results were in contrast to the self-assessment of patients by questionnaires. There was neither a dose dependency of D mean DARS volume changes over time nor of dysphonia and no correlation between volume changes, dysphagia or dysphonia.

Conclusion

Delineation of DARS on MRI co-registered to planning CT gave the opportunity to differentiate morphology better than by CT alone. Due to the small number of patients with complete MRI scans over time, we failed to detect a dose dependency of DARS and swallowing and voice disorder posttreatment.

Association between human papillomavirus status and health-related quality of life in oropharyngeal and oral cavity cancer survivors

OBJECTIVES

The human papillomavirus (HPV) is a risk factor for a subgroup of head and neck cancers (HNC). HPV-positive and HPV-negative HNC patients encompass heterogeneous groups regarding risk factors, sociodemographic and clinical characteristics, which may influence health-related quality of life (HRQL) differently. Since this has been sparsely studied, our study investigated the association between HPV status and HRQL in HNC survivors in Denmark.

MATERIALS AND METHODS

This cross-sectional study included 179 recurrence-free oropharyngeal and oral cavity squamous cell carcinoma (OSCC) survivors. HRQL was assessed on the EORTC QLQ-C30 and QLQ-H&N35 questionnaires. Linear and logistic regression models were adjusted for sociodemographic, clinical and lifestyle factors.

RESULTS

Most unadjusted results showed better HRQL among HPV-positive (n = 119) compared to HPV-negative (n = 60) OSCC survivors (average 18 months since diagnosis). After adjustments, the HPV-positive survivors reported higher role functioning (mean difference [MD] 9.2, 95% confidence interval [CI] 0.1 to -18.4), and fewer problems with speech (MD -9.0, 95% CI -18.0 to -0.1), sexuality (MD -21.9, 95% CI -38.0 to -5.9) and opening mouth (MD -13.7, 95% CI -26.6 to -0.8) compared to HPV-negative survivors.

CONCLUSION

Our findings support that HPV-positive OSCC survivors experience better HRQL than HPV-negative survivors. However, results indicate that sociodemographic, clinical and lifestyle factors explain most of the association between HPV status and HRQL. Findings suggest increased focus on the HPV-negative OSCC survivors with deteriorated HRQL in rehabilitation programs and future research to investigate the long-term effects of treatment among HPV-positive OSCC survivors who may develop symptoms later in survivorship.

Upper body motor function and swallowing impairments and its association in survivors of head and neck cancer: A cross-sectional study

Background

Upper body motor function and swallowing may be affected after curative treatment for head and neck cancer. The aims of this study are to compare maximum mouth opening (MMO), temporomandibular dysfunction (TMD), cervical and shoulder active range of motion (AROM) and strength, and swallowing difficulty between survivors of head and neck cancer (sHNC) and healthy matched controls (HMC) and to examine the correlations between these outcomes in sHNC.

Methods

Thirty-two sHNC and 32 HMC participated on the study. MMO, TMD, cervical and shoulder AROM, cervical and shoulder strength, the SPADI shoulder pain and disability indices, the Eating Assessment Tool (EAT-10) score, swallowing difficulty as determined using a visual analogue scale (VAS), and the location of disturbances in swallowing, were recorded.

Results

MMO and cervical and shoulder AROM and strength were significantly lower in sHNC, whereas FAI, SPADI score, EAT-10 and VAS were higher. The MMO, TMD, cervical and shoulder AROM, and cervical shoulder strength values showed significant correlations (some direct, others inverse) with one another. Swallowing difficulty was inversely associated with the MMO, cervical AROM and shoulder strength.

Conclusion

Compared with controls, sHNC present smaller MMO, lower cervical and shoulder AROM, lower cervical and shoulder strength and higher perception of TMD, shoulder pain and disability and swallowing difficulty. sHNC suffer impaired swallowing related to lower MMO, presence of TMD, cervical AROM and shoulder strength values. Improving these variables via physiotherapy may reduce the difficulty in swallowing experienced by some sHNC.

Long-term swallowing, trismus, and speech outcomes after combined chemoradiotherapy and preventive rehabilitation for head and neck cancer; 10-year plus update

BACKGROUND

The objective of this study was to explore the 10-year plus outcomes of Intensity Modulated Radiotherapy with concomitant chemotherapy (CRT) combined with preventive swallowing rehabilitation (CRT+) for head and neck cancer (HNC).

METHODS

Subjective and objective swallowing, trismus, and speech related outcomes were assessed at 10-year plus after CRT+. Outcomes were compared to previously published 6-year results of the same cohort.

RESULTS

Fourteen of the 22 patients at 6-year follow-up were evaluable. Although objective swallowing-related outcomes showed no deterioration (eg, no feeding tube dependency and no pneumonia), swallowing-related quality of life slightly deteriorated over time. No patients had or perceived trismus. Voice and speech questionnaires showed little problems in daily life. Overall quality of life (QOL) was good.

CONCLUSIONS

After CRT with preventive rehabilitation exercises for advanced HNC, swallowing, trismus, and speech related outcomes moderately deteriorated from 6 to 10 years, with an on average good overall QOL after.

Social participation in head and neck cancer survivors with swallowing disorder: World Health Organization Disability Assessment Schedule 2.0 study

BACKGROUND

Social function and quality of life were negatively impacted by the sequelae of treatment for the disease in the head and neck cancer survivor with swallowing disorder.

METHOD

Data from a total of 1023 survivors between July 2012 and November 2017 were collected from the Taiwan Data Bank of Persons with Disability. Nonparametric rank F test was used to analyze the influence of different variables on social participation.

RESULTS

(a) All WHODAS (World Health Organization Disability Assessment Schedule) 2.0 scores revealed significantly increased difficulty when swallowing impairment increased (P < .001). (b) Unemployment, institutionalization, severity of swallowing impairment, cancer sites, and WHODAS 2.0 score of domains 1 to 4 were negatively related to social participation, while living in rural area is related to increased social participation.

CONCLUSIONS

Social participation was negatively affected by many variables in this population. Among these variables, cancer sites and WHODAS 2.0 score of domains 1 to 4 were the strongest factors.

Monitoring and Evaluation of Late Functional Outcome in Post-treatment Follow-Up in Clinical Routine Setting

Patients treated for head and neck cancer (HNC) often suffer from severe and visible loss of function as the cancer itself and the side effects of aggressive treatments have the potential to severely affect quality of life. Therefore, the aim of follow-up is not only the early detection of potentially curable recurrences and second primary tumors but also the diagnosis and rehabilitation of functional impairments. Clear guidelines determining the frequency of follow-up visits are missing, and the impact of follow-up visits on patient's prognosis is unclear. An intensive post-treatment follow-up is needed to detect functional impairments and to initiate their treatment. The aim is an optimal rehabilitation of the patients. This article focusses on goals of aftercare treatment and describes the spectrum of long-term sequelae, and the impact of Patient Reported Outcome (PRO) instruments of which three will be introduced.

Physical and Psychological Impairments Associated with Mucositis after Oral Cancer Treatment and Their Impact on Quality of Life

BACKGROUND

Posttherapeutic mucositis is a common secondary effect of oral cancer treatment. Mucositis affects the oral mucosa, which leads to specific physical impairments in oral function and a negative impact on quality of life.

OBJECTIVE

To evaluate the impairments associated with oral mucositis and their impact on posttherapeutic quality of life.

METHODS

A retrospective analysis was conducted on 1,652 patients treated for oral cancer during the multicenter rehabilitation study of the German-Austrian-Swiss Cooperative Group on Tumors of the Maxillofacial Region (DÖSAK), which included 43 clinics from Germany, Austria, and Switzerland. The analysis was based on questionnaires filled out by patients following treatment.

RESULTS

Approximately 10% of 1,652 patients included in our study had physical or psychological impairments due to increased posttreatment oral mucositis; this was mainly due to adjuvant radiotherapy or radiochemotherapy administered. Oral mucositis was significantly associated with specific physical impairments, especially xerostomia and pain (p = 0.000), which required supportive care and analgesia (p = 0.000). Additionally, impaired ingestion and speech significantly led to psychological disorders such as public avoidance behavior and social isolation (p = 0.001). Depressive coping of disease (p = 0.001) and concomitant depressive tendencies (p = 0.004) were highly associated with mucositis, which was accompanied by diminished general condition (p = 0.001), bleak future prospects (p = 0.006), and a reduction in quality of life (p = 0.002).

CONCLUSION

Minimizing mucositis-related impairments should be a main effort in oral cancer treatment to optimize patient outcome and improve quality of life after therapy.

Quality of life and voice outcome of patients treated with transoral CO2 laser microsurgery for early glottic carcinoma (T1-T2): a 2-year follow-up study

Purpose

Longitudinal studies in laryngeal cancer can provide clinicians information about short-term and long-term functional outcomes, like quality of life (QoL) and voice outcome. This information is important when counseling patients or choosing a primary treatment modality. The present study assessed long-term (2 years) QoL and voice outcome in patients with extended T1 and limited T2 glottic carcinoma treated with transoral CO₂ laser microsurgery (TLM) (unilateral type III or bilateral type II resections).

Methods

Three questionnaires were administered: the Voice Handicap Index (VHI), the European Organization for Research and Treatment of Cancer (EORTC) QoL questionnaire (QLQ)-C30, the EORTC QLQ-HN35. A perceptual voice evaluation at six different time points was conducted: preoperatively, and postoperatively at 6 weeks, 3 months, 6 months, 1 year, and 2 years. Fluctuations over time were investigated.

Results

Sixty-one patients were included in the analysis. Patients reported high-level functioning and low symptom scores 2 years postoperatively. Gender significantly affected the VHI scores at 2 years (mean VHI scores: female 8.7 vs. male, 23.9; p = 0.023). The major improvement in VHI scores was observed within the first 6 months. The tumor stage (T1a, T1b, and T2) significantly impacted the grade (mean scores at 2 years: 1.0, 1.9, and 1.7; p = 0.001). These scores stabilized at 6 months.

Conclusions

Patients show good long-term QoL with low symptom scores, a low voice handicap, and mild to moderate dysphonia, 2 years postoperatively. Scores stabilize at 6 months and provide a clear indication of status at 1 and 2 years.

Simultaneous Radiological and Fiberendoscopic Evaluation of Swallowing ("SIRFES") in Patients After Surgery of Oropharyngeal/Laryngeal Cancer and Postoperative Dysphagia

To compare the results of a simultaneously performed videofluoroscopic swallowing study and fiberendoscopic evaluation of swallowing in patients with dysphagia after surgery and radiotherapy for oropharyngeal or laryngeal cancer. This prospective study included 31 patients who were examined simultaneously with a standardized protocol. The fiberendoscopic and videofluoroscopic swallowing loops were independently scored by two otorhinolaryngologists/phoniatricians and two radiologists. The presence of penetration/aspiration, the amount of pharyngeal residues and the position of the bolus head when triggering of pharyngeal swallow begins were evaluated. Generalized linear models were used to model the impact of rater, method, bolus and quantities as well as specified moderation effects on scorings. In addition, post hoc Wilcoxon tests were used. Rater agreement was assessed using weighted kappas and their 95% confidence intervals. A total of 202 swallow sequences in 29 patients was evaluated. Interrater agreement was substantial to excellent for both methods (weighted k = 0.979–0.613). Significant differences between both methods were found when assessing the penetration-aspiration scale (p = 0.001, tendency of higher scores by videofluoroscopic (median = 2.59) as opposed to fiberendoscopic (median = 2.14) and the residue severity scores in the valleculae (p = 0.029) and the sinus piriformes (p = 0.002) with larger residues scored by fiberendoscopic evaluation of swallowing. No significant differences were found regarding the time point of triggering (p = 0.273). Simultaneous evaluation of swallowing with FEES and VFSS showed significantly different results in symptomatic patients after tumor operation and radiotherapy.

Dental approach of orofacial pain in head and neck cancer patients

BACKGROUND

Orofacial pain (OFP) is an undesirable sensation frequently associated with head and neck cancer (HNC) and its treatment. OFP negatively impacts the quality of life of oncological patients. The approach to OFP diagnosis and management can differ if the patient visits a dentist or physician. The aim of this study was to present a case series of HNC with OFP managed by a dentist team and to discuss its role in the management of OFP.

MATERIAL AND METHODS

We recruited twenty-two adult patients with OFP and previous diagnosis of HNC referred to an academic dental clinic from 2015 to 2017.

RESULTS

Nociceptive was more frequent than mixed and neuropathic pain, however 54,4% of the cases showed a neurological component. All types of pain were managed by dentist through removal of pain's cause and appropriated local and systemic treatment. The intensity of pain was reduced in 86,3% of patients, and 45,4% of them reported absence of pain at the end of treatment.

CONCLUSIONS

Dentist's assessment plays a distinct and crucial role in the diagnosis and management of OFP in HNC patients throughout the oncological treatment. Key words:Pain, orofacial, neoplasm, head and neck, dentist.

Oncologic and functional outcomes of patients treated with transoral CO2 laser microsurgery or radiotherapy for T2 glottic carcinoma: a systematic review of the literature

PURPOSE OF REVIEW

To give an overview of the laryngeal preservation and functional outcomes of patients treated with transoral CO2 laser microsurgery (TLM) or radiotherapy for T2 glottic carcinoma. This information supports physicians and patients in treatment counselling and choices.

RECENT FINDINGS

A recent systematic review showed that local control rates at 5-year did not differ between radiotherapy and TLM for T2 glottic tumours. However, there is a lack of comparative data on laryngeal preservation as well as functional outcomes in T2 glottic carcinoma.

SUMMARY

Laryngeal preservation for T2 tumours in this review is higher for patients treated primarily with TLM (88.8 vs. 79.0%). It is important to differentiate between tumours with normal and impaired mobility (T2a and T2b) because the latter showed poorer prognosis for both TLM and radiotherapy. Involvement of the anterior commissure does not result in significantly lower oncological results, if adequately staged and treated. More studies are needed to support these data and to compare the functional outcomes between TLM and radiotherapy for T2 glottic carcinoma.

Economic evaluation of a person-centred care intervention in head and neck oncology: results from a randomized controlled trial

Purpose

Head and neck cancer and its treatment deteriorate quality of life, but symptoms improve with person-centred care. We examined the cost-effectiveness of a person-centred care intervention versus standard medical care.

Methods

In this randomized clinical trial of a person-centred intervention, patients were planned for outpatient oncology treatment in a Swedish university hospital between 2012 and 2014 and were followed during 1 year. Annual healthcare costs were identified from medical records and administrative register data. Productivity costs were calculated from reported sick leave. Health-related quality of life was collected using the EuroQol Group’s five-dimension health state questionnaire.

Results

Characteristics were similar between 53 patients in the intervention group and 39 control patients. The average total cost was Euro (EUR) 55,544 (95% confidence interval: EUR 48,474–62,614) in the intervention group and EUR 57,443 (EUR 48,607–66,279) among controls, with similar health-related quality of life.

Conclusions

This person-centred intervention did not result in increased costs and dominated the standard medical care.

A Distress Thermometer Intervention for Patients With Head and Neck Cancer

OBJECTIVES

To investigate the feasibility of an intervention using the National Comprehensive Cancer Network Distress Thermometer and Problem List with nurse-guided follow-up and the effect on depressive symptoms, health-related quality of life, and worry of cancer in patients with head and neck cancer.
.

SAMPLE & SETTING

110 patients with head and neck cancer in a two-arm randomized, controlled trial in an outpatient clinic of a university hospital. 
.

METHODS & VARIABLES

Patients were randomized to usual care (n = 57) or the intervention group (n = 53), which consisted of screening with the Distress Thermometer and Problem List plus nurse-guided follow-up lasting about 20 minutes three to four times during 12 months. Intention-to-treat analysis was performed using linear mixed models with outcomes at 6 and 12 months and baseline adjustment.
.

RESULTS

The intervention showed moderate compliance and acceptable session duration. Intervention participants were satisfied with nurses' care. Depressive symptoms, health-related quality of life, and worry of cancer were not significantly different in the two treatment groups. The intervention seemed feasible in clinical practice, but no effects on patient outcomes were seen.
.

IMPLICATIONS FOR NURSING

Patients with head and neck cancer appreciated the opportunity to discuss their problems and challenges with a nurse. Nurses supported patients with basic psychosocial care, minor interventions, and referral possibilities.

Correlation between the Voice Handicap and Swallowing Quality of Life in patients with laryngeal cancer submitted to chemoradiotherapy

Purpose To verify the correlation between the voice handicap and swallowing quality of life in individuals submitted to chemoradiotherapy for laryngeal cancer treatment. Methods Cross-sectional, observational and quantitative study. Fourteen male individuals diagnosed with laryngeal cancer were submitted to exclusive chemoradiotherapy treatment. The individuals completed the Voice Handicap Index (VHI) and the Swallowing Quality of Life (SWAL-QOL) questionnaires. Data were submitted to descriptive and inferential analysis using Spearman's Correlation Test to verify possible correlations among the scores of these instruments. Values of p ≤ 0.05 were considered statistically significant. Results No significant correlation was found between the total VHI and overall SWAL-QOL scores. However, there was significant correlation between the domain Functional of the VHI and the domains Fatigue and Social of the SWAL-QOL, between the domain Organic in the VHI and the SWAL-QOL domain Social, and total VHI score and SWAL-QOL domain Swallowing as a burden. Furthermore, chemoradiotherapy treatment had a greater impact on the voice than on the swallowing for the studied individuals. Conclusion The data showed a significant correlation between voice handicap and the impact of quality of life involving swallowing in individuals with laryngeal cancer submitted to chemoradiotherapy. This may affect individuals' emotional and social aspects, impacting their overall quality of life.

Oropharyngeal Dysphagia Evaluation Tools in Adults with Solid Malignancies Outside the Head and Neck and Upper GI Tract: A Systematic Review

Dysphagia is often associated with head and neck and upper gastrointestinal (GI) tract cancers. Evidence suggests that those with solid malignancies in other primary sites may also have swallowing difficulties. Timely and accurate identification of dysphagia is important given the impact it has on hydration, medical treatment, nutrition, prognosis, and quality of life. A systematic review was conducted to identify swallow screening, evaluation, and quality of life tools for those with solid malignancies outside the head and neck and upper GI tract. Ten electronic databases, one journal and two published conference proceedings were searched. Following deduplication, 7435 studies were examined for relevance. No tools were validated solely in this cancer population, though some included this group in larger cohorts. Comments are provided on the diagnostic properties and applicability of these tools. In the absence of appropriate diagnostic instruments, the exact prevalence of dysphagia and its impact on clinical and psychosocial well-being remain unknown. Accurate and adequate measurement of therapeutic intervention is also compromised. This review establishes the need for validated dysphagia evaluation tools for this clinical population.
