Implementing flexible endoscopic evaluation of swallow screening within annual cancer surveillance appointments to monitor for late-stage radiation-induced dysphagia: A feasibility study.

BACKGROUND: Late-stage progressive decline of swallowing function after radiotherapy for head and neck cancer (HNC) is often difficult to monitor. This study examined the feasibility and clinical outcomes of speech-language pathology implementing flexible endoscopic evaluation of swallow (FEES) screening during annual cancer surveillance visits to monitor late-stage swallowing function. METHODS: Patients >2 years post treatment who attended routine oncological visits underwent FEES screening. Feasibility (service data, stakeholder survey) and swallowing outcomes (oral intake, secretions, internal lymphedema, penetration-aspiration, and residue) were collected. RESULTS: Screening was completed with 70% (50/71) of eligible patients. Medical staff and speech-language pathologists indicated the protocol was worthwhile and achievable to incorporate into practice. Almost all patients were willing to complete the protocol annually. FEES outcomes identified 84% with dysphagia versus only 26% self-reported dysphagia. CONCLUSION: Findings indicate FEES screening incorporated into annual oncological reviews is feasible and effective at monitoring late-stage swallowing function following HNC.

Post-laryngectomy pulmonary and related symptom changes following adoption of an optimal day-and-night heat and moisture exchanger (HME) regimen.

BACKGROUND: This study examined post-laryngectomy pulmonary and related symptom changes following establishment of an optimal day/night regimen (all day/night wear of devices with improved humidification) using a new generation range of heat and moisture exchanger (HME) devices. METHODS: In Phase 1 (6 weeks), 42 post-laryngectomy HME users transitioned from their usual HME regime to equivalent new device/s (i.e., "like-for-like"). In Phase 2 (6 weeks) participants used the full range of HMEs to achieve an optimal day/night regimen. Pulmonary symptoms, device use, sleep, skin integrity, quality of life and satisfaction were examined at baseline, and weeks 2 and 6 of each Phase. RESULTS: From baseline to end of Phase 2, cough symptoms and impact significantly improved, as did sputum symptoms, sputum impact, duration and types of HMEs used, reasons for HME replacement, involuntary coughs, and sleep. CONCLUSION: The new HME range supported improved HME use, with pulmonary and related symptom benefits.

Meta-analysis on the rate of pharyngocutaneous fistula in early oral feeding in laryngectomy patients.

BACKGROUND: Laryngectomy remains a common operation in head and neck units. The operation holds significant risk of post-operative morbidity including swallowing dysfunction. The most significant post-operative concern is the formation of a pharyngocutaneous fistula [PCF], the reported incidence of which is between 3% and 65%. The purpose of this systematic review and meta-analysis was to assess the safety of initiating early oral feeding following laryngectomy and the risk of PCF formation. METHODS: A literature search was conducted through online databases: MEDLINE, EMBASE and PubMed. Eligible studies were included which contained cohorts of patients who had undergone laryngectomy, with early oral feeding commencing within seven days compared to late oral feeding. The primary outcome assessed was the incidence of PCF. Studies were excluded if cohorts had not included laryngectomy or if no comment was made on PCF formation. Meta-analysis was used to examine associations between oral feeding and PCF formation using Fixed Effect models. RESULTS: Twelve studies and 1883 patients were included after systematic review. Six studies were non-interventional whereas the remaining were randomized clinical trials. Exposure included those with early oral feeding (before seven days) or late feeding oral feeding (after seven days) and the outcome assessed was the risk of PCF formation. Results from observational studies showed a higher risk of PCF formation for early feeders compared to late feeders [RR = 1.56, 95% CI: 1.15, 2.11]. Higher risk was also observed for RCT but was not significant [RR = 1.40, 95% CI: 0.85, 2.30]. Overall, there was a 50% greater risk of PCF formation for early oral feeding compared to late oral feeding [RR = 1.51, 95% CI: 1.17, 1.96]. CONCLUSION: While early oral feeding can reduce post-laryngectomy patients' hospital stay and improve psychological wellbeing, there is a significant relative risk of PCF development within this group. However, this must be taken in context of the significant heterogeneity that exists within the literature.

Optimising Radiation Therapy Dose to the Swallowing Organs at Risk: An In Silico Study of feasibility for Patients with Oropharyngeal Tumours.

Recent evidence suggests that reducing radiotherapy dose delivered to specific anatomical swallowing structures [Swallowing Organs at Risk (SWOARs)] may improve swallowing outcomes post-treatment for patients with head and neck cancer. However, for those patients with tumours of the oropharynx, which typically directly overlap the SWOARs, reducing dose to these structures may be unachievable without compromising on the treatment of the disease. To assess the feasibility of dose reduction in this cohort, standard IMRT plans (ST-IMRT) and plans with reduced dose to the SWOARs (SW-IMRT) were generated for 25 oropharyngeal cancer patients (Brouwer et al. in Radiother Oncol 117(1):83-90, https://doi.org/10.1016/j.radonc.2015.07.041 , 2015; Christianen et al. in Radiother Oncol 101(3):394-402, https://doi.org/10.1016/j.radonc.2011.05.015 , 2011). ST-IMRT and SW-IMRT plans were compared for: mean dose to the SWOARs, volume of pharynx and larynx receiving 50 Gy and 60 Gy (V50 and V60 respectively) and overlap between the tumour volume and the SWOARs. Additionally, two different SWOARs delineation guidelines (Brouwer et al. in Radiother Oncol 117(1):83-90, https://doi.org/10.1016/j.radonc.2015.07.041 , 2015; Christianen et al. in Radiother Oncol 101(3):394-402, https://doi.org/10.1016/j.radonc.2011.05.015 , 2011) were used to highlight differences in calculated volumes between existing contouring guidelines. Agreement in SWOARs volumes between the two guidelines was calculated using a concordance index (CI). Despite a large overlap between the tumour and SWOARs, significant (p < 0.05) reductions in mean dose to 4 of the 5 SWOARs, and V50/V60 for the pharynx and larynx were achieved with SW-IMRT plans. Low CIs per structure (0.15-0.45) were found between the two guidelines highlighting issues comparing data between studies when different guidelines have been used (Hawkins et al. in Semin Radiat Oncol 28(1):46-52, https://doi.org/10.1016/j.semradonc.2017.08.002 , 2018; Brodin et al. in Int J Radiat Oncol Biol Phys 100(2):391-407, https://doi.org/10.1016/j.ijrobp.2017.09.041 , 2018). This study found reducing dose to the SWOARs is a feasible practice for patients with oropharyngeal cancer. However, future prospective research is needed to determine if the extent of dose reduction achieved equates to clinical benefits.

Content analysis of rehabilitation goals for patients following non-surgical head and neck cancer treatment.

PURPOSE: Following head and neck cancer (HNC) treatment, individuals experience an array of side effects which can impact on physical, emotional, and practical aspects of their lives. Responsive, supportive rehabilitation services are therefore essential to address ongoing survivorship needs. This study examined the nature of patient-reported goals from acute to long-term post-treatment, to inform design/delivery of future rehabilitation services. METHODS: Using a cross-sectional cohort design, 91 patients between 2 weeks and 5 years of post non-surgical HNC treatment (acute n = 29; sub-acute n = 28; long-term n = 34), provided their top four rehabilitation goals considering any aspect of their lives. Content analysis was used to categorise responses at each time point. RESULTS: Three core categories of patient goals were identified relating to: (1) treatment side effects (TSE), (2) overall health (OH), and (3) living life (LL). TSE goals were a priority during the acute and sub-acute phases, with less focus long-term. LL goals were prevalent across all time points, though increased in the long-term. Approximately a third of all goals at each time point related to OH. CONCLUSIONS: A variety of rehabilitation goals were identified, and the focus shifted over time. These data highlight the importance of changing the focus of rehabilitation as patients' priorities vary over time. Early multidisciplinary care from allied health services is crucial to provide support with managing side effects and returning to daily activities. In the long-term, greater input from services to address health, nutrition, leisure, and fitness goals may be more beneficial.

Treatment toxicities and their impact on oral intake following non-surgical management for head and neck cancer: a 3-year longitudinal study.

PURPOSE: Patients who receive (chemo)radiotherapy [(C)RT] for head and neck cancer (HNC) experience multiple treatment effects. However, the presence and recovery of treatment toxicities and how these impact on oral intake over time post-treatment are not fully understood. The primary aim of this study was to examine patient perceptions of the toxicities present and which are barriers to oral intake, up to 3 years post (C)RT. The secondary aim was to identify mealtime strategies used to optimise oral intake. METHODS: A prospective cohort of 96 patients after completion of (C)RT for HNC reported the presence of toxicities, if they were barriers to oral intake, and use of any mealtime strategies at the end of treatment (EoT), and at 3, 6, 12, 24, and 36 months post-treatment. RESULTS: All toxicities and reported barriers changed over time (p < 0.05) except trismus. Odynophagia, reduced appetite, and fatigue improved (p < 0.05) by 3 months. Significantly less patients reported xerostomia and dysgeusia as barriers to oral intake at 3 months despite no improvement in their presence. No change in the presence of any toxicity or its impact on oral intake occurred from 12 to 36 months, with exception of dentition problems which significantly increased at 36 months. Alternating food/fluids was the most frequently used mealtime swallowing strategy at all time points beyond the EoT. CONCLUSIONS: The dysphagia and associated toxicities HNC patients experience are chronic in nature. Rehabilitation should include mealtime strategies and support with adjusting to the changing presence and impact of toxicities on oral intake.

Total laryngectomy with primary tracheoesophageal puncture: Intraoperative versus delayed voice prosthesis placement.

BACKGROUND: Studies support using intraoperative voice prosthesis insertion performed at the time of primary tracheoesophageal puncture (TEP) during laryngectomy. However, none have compared intraoperative voice prosthesis insertion with delayed voice prosthesis insertion. The purpose of this study was to prospectively examine patient, services, and cost benefits of intraoperative versus delayed voice prosthesis placement. METHODS: Voice prosthesis use, duration to the first voice prosthesis change, early communication, and costs were compared between 14 patients who underwent a laryngectomy and who received intraoperative voice prosthesis placement, and 10 patients who underwent initial catheter stenting and then delayed voice prosthesis insertion. RESULTS: Intraoperative voice prosthesis placement was associated with significantly fewer early device changes (1.4 vs 2), voice prosthesis changes because of resizing (8% vs 80%), longer durations to initial voice prosthesis change (159.7 vs 24.5 days), earlier commencement of voice rehabilitation (13.2 vs 17.6 days), reduced length of hospital stay (17.2 vs 24.5 days), and cost savings of $559.83/person. CONCLUSION: Superior clinical and patient benefits are associated with intraoperative voice prosthesis placement during primary TEP. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1138-1144, 2017.

Pretreatment factors associated with functional oral intake and feeding tube use at 1 and 6 months post-radiotherapy (+/- chemotherapy) for head and neck cancer.

A proportion of patients with head and neck cancer (HNC) experience significant swallowing difficulty during and post-radiotherapy/chemoradiotherapy (RT/CRT). Identifying patients during the pretreatment period who are anticipated to have compromised oral intake would allow for early and accurate patient education, and prioritisation of their management. Ascertaining a clear set of pretreatment predictors from the literature is challenging due to heterogeneity in study designs and patient cohorts, with minimal prospective data available (especially at 1-month post-treatment). The objectives of this study were to investigate which pretreatment factors predicted compromised oral intake and feeding tube use at 1 and 6 months post-RT/CRT. Prospective data were collected on 80 consecutive HNC patients receiving RT/CRT from 2011 to 2014. The primary outcome was to identify predictors of a modified diet at 1 and 6 months post-RT/CRT. Secondary outcomes were to identify predictors of feeding tube use at these time intervals, and <6 vs. >6 week duration of feeding tube use. Multivariate analysis revealed bilateral neck radiotherapy treatment was a strong predictor of modified diets at 1 month (p < 0.001), and T-stages T3/T4 a predictor of modified diets at 6 months (p = 0.03). Patients treated with concurrent CRT (p = 0.02) and bilateral neck treatment (p = 0.02) predicted feeding tube use at 1 month, and concurrent CRT predicted feeding tube use for >6 weeks (p = 0.04). Therefore, patients receiving bilateral neck treatment and/or CRT are at greatest risk of requiring modified diets and feeding tube use early post-treatment, and should be prioritised for intervention and ongoing support.
