Telemedicine-enabled biofeedback electropalatography rehabilitation (TEBER): A pilot study for patients treated with surgery for oral cavity carcinoma

BACKGROUND

To address the rehabilitative barriers to frequency and precision of care, we conducted a pilot study of a biofeedback electropalatography (EPG) device paired with telemedicine for patients who underwent primary surgery +/- adjuvant radiation for oral cavity carcinoma. We hypothesized that lingual optimization followed by telemedicine-enabled biofeedback electropalatography rehabilitation (TEBER) would further improve speech and swallowing outcomes after "standard-of-care" SOC rehabilitation.

METHOD

Pilot prospective 8-week (TEBER) program following 8 weeks of (SOC) rehabilitation.

RESULTS

Twenty-seven patients were included and 11 completed the protocol. When examining the benefit of TEBER independent of standard of care, "range-of-liquids" improved by +0.36 [95% CI, 0.02-0.70, p = 0.05] and "range-of-solids" improved by +0.73 [95% CI, 0.12-1.34, p = 0.03]. There was a positive trend toward better oral cavity obliteration; residual volume decreased by -1.2 [95% CI, -2.45 to 0.053, p = 0.06], and "nutritional-mode" increased by +0.55 [95% CI, -0.15 to 1.24, p = 0.08].

CONCLUSION

This pilot suggests that TEBER bolsters oral rehabilitation after 8 weeks of SOC lingual range of motion.

Functional Oral Intake in Primary Versus Salvage Laryngectomy

OBJECTIVE

Advanced-stage laryngeal squamous cell carcinoma is treated with primary surgery or chemoradiation. We aim to determine if there are differences in postoperative functional oral intake in primary (PL) versus salvage laryngectomees (SL).

STUDY DESIGN

Retrospective cohort study.

SETTING

Patients who underwent laryngectomy between 2011 and 2021.

METHODS

We examined demographic, diagnostic, treatment, and swallow function data pre- and postoperatively. A follow-up survey was distributed to assess current swallow status.

RESULTS

One hundred twenty-five patients were included. Preoperatively, 68.8% of patients reported dysphagia. Median functional oral intake score (FOIS) was 4.0 [interquartile range, IQR: 1.0-6.75]. The SL group had lower preop FOIS [2.0; IQR: 1.0-4.75] that did not reach significance compared to the PL group [4.5; IQR: 1.0-7.0] (P = .052). 73.4% of patients had a feeding tube. The PL group was more likely to have the tube removed [odds ratio, OR: 2.4; confidence interval, CI: 1.0-5.7]. The SL group was more likely to require feeding tube placement more than 6 months postop [OR: 6.9; CI: 1.65-32.6]. SL FOIS scores improved by 3 months postop to 5 (SL ΔFOIS = 3, P = .0150). PL scores improved to 7 [PL ΔFOIS = 2, P = .0005] at 12 to 15 months. Sixty-nine patients were contacted for a follow-up survey and 16 completed this survey. 30.4% patients reported dietary restrictions (mean 4.4 years postop).

CONCLUSION

Patients undergoing SL appear to obtain similar swallow outcomes compared to PL at 3 to 6 months postlaryngectomy, but plateau. The PL group continues to improve up to 1 year postoperatively. Fifty percent of patients report on-going dysphagia after 5 years.

Glossectomy for the treatment of oral cavity carcinoma: Quantitative, functional and patient-reported quality of life outcomes differ by four glossectomy defects

OBJECTIVE

The goal was to characterize four clinically distinct glossectomy defects to establish significant quantitative cut points using functional metrics, the MD Anderson Dysphagia Index (MDADI) and speech intelligibility.

METHODS

Population included 101 patients treated with surgery, adjuvant radiation per NCCN guidelines, and ≥ 12 months follow-up.

RESULTS

Defect groups: subtotal hemiglossectomy (1), hemiglossectomy (2), extended hemiglossectomy (3) and oral glossectomy (4) were compared: All outcomes supported a four defect model. Intergroup comparison of outcomes with subtotal hemiglossectomy as reference (p value): Tongue Protrusion <0.001,<0.001,<0.001; Elevation <0.001,<0.001,<0.001; Open Mouth Premaxillary Contact Elevation <0.001,<0.001,<0.001; Obliteration 0.6,<0.001,<0.001; Normalcy of Diet, <0.3,<0.001,<0.001; Nutritional Mode, <0.9,<0.8,<0.001; Range of Liquids, <0.4,<0.016,<0.02; Range of Solids, <0.5,<0.004,<0.001; Eating in Public, <0.2,<0.002,<0.03; Understandability of Speech, <0.9,<0.001,<0.001; Speaking in Public, <0.4,<0.03,<0.001; MDADI, <0.4,<0.005,<0.01; Single Word Intelligibility, <0.4,<0.1,<0.001; Sentence Intelligibility, <0.5,<0.08,<0.001; Words Per Minute Intelligibility, <0.6,<0.04,<0.001; Sentence Efficiency Ratio, <0.4,<0.03,<0.002. Proportion of patients by 4 defect groups who underwent: tissue transplantation, 51%,93.9%,100%,100%.Radiation,24%,67%,88%,80%.Between hemiglossectomy and extended hemiglossectomy, the defect extends into the contralateral floor of the mouth and/or the anterior tonsillar pillar; resection of these subunits limits tongue mobility with an impact on functional outcome and MDADI. Between extended hemiglossectomy and oral glossectomy, the defect extends to include the tip of the tongue and appears to impact functional outcome and MDADI.

CONCLUSIONS

Subtotal hemiglossectomy, hemiglossectomy, extended glossectomy and oral glossectomy are associated with quantitative (elevation, protrusion, open mouth premaxillary contact and obliteration), qualitative (speech and swallowing) and MDADI differences, suggesting that these 4 ordinal defect groups are distinct.

Total Glossectomy With Free Flap Reconstruction: Twenty-Year Experience at a Tertiary Medical Center

OBJECTIVES/HYPOTHESIS

To characterize the demographics, clinicopathologic characteristics, and treatment and reconstructive outcomes of patients who underwent total glossectomy STUDY DESIGN: Retrospective chart review at an academic tertiary-care medical center.

METHODS

All patients who had undergone total glossectomy (as an individual procedure or as part of a more extensive resection) between January 1, 1995 and December 31, 2014 were included in the analysis. Patient characteristics and clinical outcomes were reviewed.

RESULTS

Forty-eight patients underwent total glossectomy for oral tongue and base of tongue cancer. The mean age of the patients was 56 (range, 29-92 years). History of tobacco and heavy alcohol use was found in 76% and 11% of patients, respectively. The majority of patients had advanced cancer (91.7% at stage IV), and 60.4% had salvage therapy for recurrent disease. T4 disease comprised 81% of patients. Sixty percent had clinical or radiographic evidence of nodal metastasis. Reconstruction of the defect was performed with free flaps from the rectus abdominus (40%), fibula (25%), anterolateral thigh (23%), and other donor tissues. One- and 5-year survival rates were 42% and 26%, with locoregional and distant recurrence reported at 36% and 25%, respectively.

CONCLUSIONS

Total glossectomy for oncologic control is most commonly performed in patients who have stage IV cancers. Despite high reconstructive success rates, the likelihood of locoregional and distance recurrence was high. Most patients can communicate intelligibly and achieve decannulation, but swallowing outcomes remain guarded, especially considering previous irradiation and resection of the base of tongue.

Structured review of papers reporting specific functions in patients with cancer of the head and neck: 2006 - 2013

Health-related quality of life (HRQoL) focuses on 4 core domains: physical and psychological function, social interaction, disease, and treatment-related symptoms, and is a key outcome in patients with cancer of the head and neck. We reviewed papers published between 2006 and 2013 that used validated questionnaires to report functional outcome in this group. A total of 572 papers were identified and 118 of them concerned function. Specific outcomes included anxiety, chewing, maxillectomy, mucositis, pain, shoulder function, and trismus. The specific functions most often identified were xerostomia, speech or voice, and swallowing or dysphagia. A considerable body of evidence has now accumulated on HRQoL and functional outomes although the precise role of HRQoL during the planning of treatment remains controversial. Over time, the emphasis of the studies included has tended to move away from the reporting of outcomes in general to more hypothesis-driven and group-specific work.

Levels of scientific evidence of the quality of life in patients treated for oral cancer

Treatments used in cancer of the oral cavity have great impact on the physical, psychological and functional state of patients. There has been increasingly interest in evaluating the health-related quality of life using questionnaires among patients treated with oral cancer. Up to our knowledge no review on this theme has incorporated the level of evidence of the single identified studies. The objective of the present study is to determinate results and conclusions about the health-related quality of life of these patients, in view of scientific evidence. In general, the diversity of designs, level of evidence and questionnaires used for their assessment does not affect results, which indicate a decline in the health related quality of life after treatment. This decline is greater when the tumor is large in size, and when radiotherapy is used, though the situation is seen to improve over the span of a year. Questionnaires on health-related quality of life provide concrete information regarding the impact of cancer treatment on patients.

Preservation of organ function in head and neck cancer

Preservation of function is a crucial aspect for the evaluation of therapies applied in the field of head and neck cancer. However, preservation of anatomic structures cannot automatically be equated with preservation of function. Functional outcome becomes increasingly important particularly for the evaluation of alternative treatment options with equivalent oncological outcomes.AS A RESULT, PRESENT STUDIES TAKE INTO ACCOUNT THREE TOPIC AREAS WITH VARYING EMPHASIS: (1) the effects of cancer therapy on essential physiological functions, (2) additional therapy-induced side-effects and complications, and (3) health-related quality of life. The present article summarizes vital aspects of clinical research from recent years. Functional outcomes after surgical and non-surgical treatment approaches are presented according to tumor localization and staging criteria. Additional methodological aspects relating to data gathering and documentation as well as challenges in implementing the results in clinical practice are also discussed.

Long-term quality of life in young adults treated for oral cavity squamous cell cancer

OBJECTIVES

We assessed the long-term quality of life (QOL) in patients who survived oral cavity squamous cell cancer when they were young and looked for any clinical factors that might adversely affect function and QOL.

METHODS

We performed a retrospective case series and questionnaire survey in a tertiary care center. The subjects were consecutive patients treated for oral cancers during a 25-year period, when they were 40 years of age or less. The patients completed the University of Washington Quality of Life questionnaire and the M. D. Anderson Dysphagia Inventory (MDADI). We made an overall descriptive report of swallowing and QOL measures in the study population and looked for any clinical factors associated with functional outcomes.

RESULTS

Among the 62 patients treated over the course of 25 years, 46 were alive and disease-free. Twenty-six participated. The median follow-up duration was 14.7 years (range, 3 to 27 years). Age at diagnosis and duration of follow-up did not correlate with overall QOL or health-related QOL. Seventy-seven percent rated their overall QOL as outstanding, very good, or good. The key domains affected by cancer were appearance, mood, saliva, and shoulder function. Radiotherapy significantly adversely affected the QOL. The median MDADI scores on all 4 subscales were at least 85%. Higher T-stage and radiotherapy were significantly associated with lower scores on all subscales.

CONCLUSIONS

The long-term health-related QOL in this cohort was quite good. Radiotherapy and tumor stage correlated with swallowing outcomes, and only radiotherapy seemed to adversely affect the overall QOL.

Evaluation of the limitations of using the University of Washington Quality of Life swallowing domain alone to screen patients in the routine clinical setting

A broad patient-completed screening tool in routine clinical practice in head and neck oncology has merit, but clinicians should be aware that its simplicity could lead to some patients and the detail of their problems being missed. The purpose of this study was to compare the University of Washington Quality of Life (UWQoL) swallowing domain with the MD Anderson Dysphagia Inventory (MDADI) in relation to the need for interventions for swallowing around one year after treatment. The group comprised 112 consecutively referred patients to speech and language therapy between January 2007 and August 2009 after primary operation for previously untreated oral and oropharyngeal squamous cell carcinoma (SCC). A total of 78 patients completed questionnaires (median time of assessment 11.7 months, IQR 6.1-12.2). There were significant (p<0.001) and moderately strong correlations (rs=0.51-0.62) between the UWQoL swallowing domain score and MDADI subscales and total scores, and also with individual MDADI questions: taking a great deal of effort (rs=0.71); being upset (rs=0.61); and not going out (rs=0.62) were the strongest in regard to swallowing. Use of a gastrostomy tube was associated with worse UWQoL and MDADI scores. In conclusion, patients who score 100 on the UWQoL do not require swallowing to be evaluated further. Those who score 70 could benefit from the detailed MDADI to help to clarify the specific problem and the impact it has before being referred to speech and language therapy. Those who score less than 70 should be brought to the attention of speech and language therapists to confirm that appropriate support and intervention are in place.
