Effect of Augmentative Technology on Communication and Quality of Life After Tracheostomy or Total Laryngectomy.

OBJECTIVE: Surgical procedures that render patients acutely aphonic can cause them to experience significant anxiety and distress. We queried patient perceptions after tracheostomy or laryngectomy and investigated whether introducing augmentative technology was associated with improvement in patient-reported outcomes. METHODS: Participants included hospitalized patients who acutely lost the ability to speak due to tracheostomy or total laryngectomy from April 2018 to December 2019. We distributed questions regarding the patient communication experience and relevant questions from the validated V-RQOL questionnaire (Voice-Related Quality of Life). Patients were offered a tablet with the electronic communication application Verbally. Pre- and postintervention groups were compared with chi-square analyses. RESULTS: Surveys were completed by 35 patients (n = 18, preintervention; n = 17, postintervention). Prior to using augmentative technology, 89% of patients who were aphonic reported difficulty communicating, specifically noting breathing or suctioning (56%), treatment and discharge plans (78%), or immediate needs, such as pain and using the bathroom (39%). Communication difficulties caused anxiety (55%), depression (44%), or frustration (62%), and 92% of patients were interested in using an electronic communication device. Patients reported less trouble communicating after the intervention versus before (53% vs 89%, P = .03), including less difficulty communicating about treatment or discharge plans (35% vs 78%, P < .01). V-RQOL scores were unchanged. DISCUSSION: Acute loss of phonation arising from surgery can be highly distressing for patients, and use of augmentative technology may alleviate some of these challenges by improving communication. Further studies are needed to identify what additional strategies may improve overall well-being. IMPLICATIONS FOR PRACTICE: Electronic communication devices may benefit patients with acute aphonia.

Predictors of Stricture and Swallowing Function Following Salvage Laryngectomy.

BACKGROUND: Long-term functional outcomes are poorly characterized for salvage laryngectomy. We identified predictors of esophageal stricture and swallowing function after salvage laryngectomy in a large cohort. METHODS: A retrospective study of 233 patients who underwent salvage total laryngectomy for recurrent/persistent squamous cell carcinoma of the larynx or hypopharynx after radiation (XRT) or chemoradiation (CRT) was performed. Primary outcomes were esophageal dilation within 1 year, time to dilation, and gastrostomy tube dependence. Multivariate logistic and Cox regressions were used for statistical analysis. RESULTS: Dilation was performed in 29.9% of patients. Dilation was twice as likely in patients with post-operative fistula compared to those without (Hazard Ratio (HR) 2.10, 95% Confidence Interval (CI) 1.06-4.13, P = .03). Every year between XRT/CRT and salvage was associated with 10% increase in dilation (HR 1.09, 95% CI 1.03-1.17, P = .01). No factors were associated with dilation by 1 year. About 10% of patients were at least partially gastrostomy tube-dependent 1 year post-operatively. At last follow-up (median 29 months), this rate was 13%. Patients with supraglottic recurrence had an increased risk of gastrostomy tube dependence at 1 year compared to glottic (OR 16.7, 95% CI 1.73-160, P = .02). For every 10 pack years pre-salvage, the OR of requiring tube feeds at last follow-up was 1.24 (95% CI 1.04-1.48, P = .02). CONCLUSIONS: Fistula and pre-salvage smoking were associated with stricture post-salvage laryngectomy. No factors were associated with dilation by 1 year. Supraglottic recurrence and smoking were associated with gastrostomy tube dependence. These findings are important for pre-operative counseling prior to salvage laryngectomy.

Early MRI Blood Volume Changes in Constrictor Muscles Correlate With Postradiation Dysphagia.

PURPOSE: Predicting individual patient sensitivity to radiation therapy (RT) for tumor control or normal tissue toxicity is necessary to individualize treatment planning. In head and neck cancer, radiation doses are limited by many nearby critical structures, including structures involved in swallowing. Previous efforts showed that imaging parameters correlate with RT dose; here, we investigate the role of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) blood volume (BV) changes in predicting dysphagia. METHODS AND MATERIALS: This study included 32 patients with locally advanced oropharyngeal squamous cell carcinoma treated with definitive chemoradiation on an institutional protocol incorporating baseline and early midtreatment DCE-MRI. BV maps of the pharyngeal constrictor muscles (PCM) were created, and BV increases midtreatment were correlated with the following parameters at 3 and 12 months post-RT: RT dose, Dynamic Imaging Grade of Swallowing Toxicity swallow score, aspiration frequency, European Organisation for Research and Treatment of Cancer HN35 patient-reported outcomes, physician-reported dysphagia, and feeding tube (FT) dependence. RESULTS: The mean BV to the PCMs increased from baseline to fraction 10, which was significant for the superior PCM (P = .006) and middle PCM (P < .001), with a trend in the inferior PCM where lower mean doses were seen (P = .077). The factors associated with FT dependence at 3 months included BV increases in the total PCM (correlation, 0.48; P = .006) and middle PCM (correlation, 0.50; P = .004). A post-RT increase in aspiration was associated with a BV increase in the superior PCM (correlation, 0.44; P = .013),and the increase in the total PCMs was marginally significant (correlation, 0.34; P = .06). The best-performing models of FT dependence (area under the receiver operating curve [AUC] = 0.84) and aspiration increases (AUC = 0.78) included BV increases as well as a mean RT dose to middle PCM. CONCLUSIONS: Our results suggest that midtreatment BV increases derived from DCE-MRI are an early predictor of dysphagia. Further investigation of these promising imaging markers to assess individual patient sensitivity to treatment and the patient's subsequent risk of toxicities is warranted to improve personalization of RT planning.

Characterization of very late dysphagia after chemoradiation for oropharyngeal squamous cell carcinoma.

OBJECTIVES: Improved prognosis for p16+ oropharyngeal squamous cell carcinoma (OPSCC) has led to efforts to mitigate long-term complications of treatment, which remains poorly defined in late survivors. Here we characterize very late dysphagia in OPSCC. MATERIALS AND METHODS: Long-term review of 93 p16+ OPSCC patients treated with chemoradiation was performed. We scored videofluoroscopic swallow studies (VFSS) according to the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale. Very late dysphagia was defined >2.5 years from end of treatment. Fine-Gray regression models were used to assess dysphagia with competing risk of death. RESULTS: Median follow up was 10.5 years. 402 total VFSS were assessed (median 4 per patient, range 0-8). 15.1% of patients had a DIGEST score ≥2 very late after treatment. Very late DIGEST score ≥2 correlated with T-stage (HR 1.7, p = 0.049), second cancer (HR 6.5, p = 0.004), superior pharyngeal constrictor dose (HR 1.11, p = 0.050), total tongue dose (HR 1.07, p = 0.045), but not hypoglossal nerve dose (p > 0.2). Seven patients (7.5%) had late progressive dysphagia, defined as DIGEST score that increased by ≥2 beyond one year after treatment, and this correlated with higher ipsilateral hypoglossal nerve D1cc dose (75 vs 72 Gy, p = 0.037). CONCLUSION: In p16+ OPSCC patients treated with definitive chemoradiation, at least 7.5% developed late progressive dysphagia, and 15.1% experienced moderate dysphagia >2.5 years from treatment. Our study suggests that dose to tongue musculature may be associated with very late dysphagia, and hypoglossal nerve dose may be associated with late progressive dysphagia. More intensive long-term dysphagia survivorship monitoring is suggested.
