Latin American Consensus on the Treatment of Head and Neck Cancer

Head and neck squamous cell carcinoma (HNSCC) is well known as a serious health problem worldwide, especially in low-income countries or those with limited resources, such as most countries in Latin America. International guidelines cannot always be applied to a population from a large region with specific conditions. This study established a Latin American guideline for care of patients with head and neck cancer and presented evidence of HNSCC management considering availability and oncologic benefit. A panel composed of 41 head and neck cancer experts systematically worked according to a modified Delphi process on (1) document compilation of evidence-based answers to different questions contextualized by resource availability and oncologic benefit regarding Latin America (region of limited resources and/or without access to all necessary health care system infrastructure), (2) revision of the answers and the classification of levels of evidence and degrees of recommendations of all recommendations, (3) validation of the consensus through two rounds of online surveys, and (4) manuscript composition. The consensus consists of 12 sections: Head and neck cancer staging, Histopathologic evaluation of head and neck cancer, Head and neck surgery-oral cavity, Clinical oncology-oral cavity, Head and neck surgery-oropharynx, Clinical oncology-oropharynx, Head and neck surgery-larynx, Head and neck surgery-larynx/hypopharynx, Clinical oncology-larynx/hypopharynx, Clinical oncology-recurrent and metastatic head and neck cancer, Head and neck surgery-reconstruction and rehabilitation, and Radiation therapy. The present consensus established 48 recommendations on HNSCC patient care considering the availability of resources and focusing on oncologic benefit. These recommendations could also be used to formulate strategies in other regions like Latin America countries.

Swallowing Function After Treatment of Laryngeal Cancer

Dysphagia is a common functional outcome following treatment of laryngeal cancer. Despite curative advances in both nonsurgical and surgical approaches, preserving and optimizing swallowing function is critical. Understanding the nature and severity of dysphagia depending on initial tumor staging and treatment modality and intensity is crucial. This chapter explores current evidence on the acute and chronic impacts of treatments for laryngeal cancer on swallow function, as well as the medical and nonmedical management of dysphagia in this population.

Course of social support and associations with distress after partial laryngectomy

PURPOSE

Social support has been shown to be positively associated with quality of life and adjustment after a cancer diagnosis. The present study investigates the course of social support up to one year after partial laryngectomy and its association with distress.

DESIGN

Longitudinal questionnaire study.

SAMPLE

A total of 428 patients after partial laryngectomy (mean age: 64, SD = 11, 91% male).

METHODS

Patients completed questionnaires before treatment (t1), one week after a partial laryngectomy (t2), 3 months (t3), and one year (t4) thereafter. Social support was evaluated at t2, t3, and t4 using a brief version of the Social Support Questionnaire. Distress was measured at t2, t3, and t4 using the HADS. Descriptive statistics for social support were computed across the three measurement points. Changes were analyzed by Wilcoxon signed-rank tests. Associations with distress were identified using linear regression analyses.

FINDINGS

Social support increased between t2 and t3 and decreased to baseline level between t3 and t4. Distress at t2 was associated with social support at t2 (B = -0.15, p < 0.01) and distress at t3 with social support at t3 (B = -0.19, p < 0.01). Distress at t4 was related to social support at t2 (B = -0.10, p = 0.05).

CONCLUSIONS

Although perceived social support increases after partial laryngectomy, it decreases again during the course of aftercare.

IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS OR POLICY

Social support resources should be assessed to identify patients at risk for worse psychological well-being.

Evolution of Nutritional Status in Patients with Advanced Head and Neck Cancer Undergoing Surgical Treatment or Organ Preservation Protocol

We sought to evaluate the evolution of the nutritional status of patients with advanced cancer of the upper aerodigestive tract undergoing surgical treatment (SURG) or organ preservation protocol (OP). Evaluations were conducted at the beginning and end of treatment, including weight, body composition and Patient-Generated Subjective Global Assessment (PG-SGA). Each group was comprised of 29 patients. Initially, malnutrition rates were 65.5% and 51.7% in the SURG and OP groups, respectively. At the end, the values went to 55.1% in SURG and 79.3% in OP. In the OP, there was a reduction in weight (P = 0.001), fat mass (P = 0.006), fat free mass (P = 0.002), and muscle mass (P = 0.005) and an increase in scores of the PG-SGA (P = 0.008). The same was not observed in SURG, except for the weight decrease (P = 0.025). Malnutrition was prevalent in both treatment groups and patients in OP were at greater risk of nutritional decline.

European white paper: oropharyngeal dysphagia in head and neck cancer

Purpose

To develop a European White Paper document on oropharyngeal dysphagia (OD) in head and neck cancer (HNC). There are wide variations in the management of OD associated with HNC across Europe.

Methods

Experts in the management of specific aspects of OD in HNC across Europe were delegated by their professional medical and multidisciplinary societies to contribute to this document. Evidence is based on systematic reviews, consensus-based position statements, and expert opinion.

Results

Twenty-four sections on HNC-specific OD topics.

Conclusion

This European White Paper summarizes current best practice on management of OD in HNC, providing recommendations to support patients and health professionals. The body of literature and its level of evidence on diagnostics and treatment for OD in HNC remain poor. This is in the context of an expected increase in the prevalence of OD due to HNC in the near future. Contributing factors to increased prevalence include aging of our European population (including HNC patients) and an increase in human papillomavirus (HPV) related cancer, despite the introduction of HPV vaccination in various countries. We recommend timely implementation of OD screening in HNC patients while emphasizing the need for robust scientific research on the treatment of OD in HNC. Meanwhile, its management remains a challenge for European professional associations and policymakers.

Survival differences between definitive radiotherapy and surgery followed by adjuvant radiotherapy in supraglottic and hypopharyngeal carcinoma

Background:

Organ preservation has long been a consideration in the treatment of supraglottic and hypopharyngeal carcinoma to improve the quality of life (QOL). Definitive radiotherapy (DRT) with or without systematic treatment, such as chemotherapy, is always the first choice to achieve improved QOL. This retrospective study focused on the survival differences between DRT and surgery followed by adjuvant radiotherapy (S + RT) in supraglottic and hypopharyngeal carcinoma.

Methods:

This study included adult patients with supraglottic or hypopharyngeal carcinoma undergoing single-modality treatment with either DRT or S + RT between January 2012 and August 2016. A total of 59 patients were identified, of whom 31 were treated with DRT, and 28 were treated with S + RT. In the 31 cases of DRT, 23 cases were treated with concurrent chemoradiotherapy (CRT), one case was treated with DRT plus cetuximab, and seven cases were treated with DRT alone. Of the other 28 cases of S + RT, 15 cases were treated with adjuvant concurrent CRT. Survival analysis was used to compare the overall survival (OS), local recurrence-free survival (LRFS) and distant metastasis-free survival (DMFS) between DRT and S + RT groups.

Results:

The median follow-up was 20 months (range, 4–67 months). The patients of the two groups were similar with respect to mean age, original sites, and tumor stages. The 1-, 2-, and 5-year OS rates were 80.6%, 53.4%, and 24.7% for the DRT group and 85.7%, 67.1%, and 24.7% for the S + RT group, respectively. There was no significant difference between the two groups (χ² = 3.183, P = 0.074). The 1-, 2-, and 5-year LRFS and DMFS were 90.4%, 61.7%, and 18.0% and 87.4%, 49.2%, and 9.9%, respectively, and no statistical difference was observed between the two groups (LRFS: χ² = 0.028, P = 0.868; DMFS: χ² = 3.347, P = 0.067). No significant difference was found between the two groups in acute radiotoxicity.

Conclusion:

Without loss of laryngeal function, the survival of DRT is comparable to that of S + RT in supraglottic and hypopharyngeal carcinoma.

Diagnosis and treatment of oropharyngeal dysphagia after total laryngectomy with or without pharyngoesophageal reconstruction: Systematic review

Background

This systematic review qualitatively summarizes the current literature on diagnosis and treatment of oropharyngeal dysphagia (OD) after total laryngectomy (TLE).

Methods

Electronic databases PubMed, Embase, and the Cochrane Library were used. Two independent reviewers carried out the literature search and assessed the methodological quality of the included studies using a critical appraisal tool.

Results

Forty‐four articles met the inclusion criteria. Of these, 35 studies were on diagnosis, four on therapy, and five on both diagnosis and treatment of OD following TLE. Study aims, swallowing‐assessment methods, and main findings of the included studies were summarized and presented.

Conclusions

The reviewers found heterogeneous outcomes and serious methodological limitations, which prevented us from pooling data to identify trends that would assist in designing best clinical practice protocols for OD following TLE. Further research should focus on several remaining gaps in our knowledge on diagnosis and treatment interventions for OD following TLE.

Community listeners' perceptions of voice function post-radiotherapy for laryngeal cancer

PURPOSE

Successful communication is influenced by communication partners, the community and communication environment. This study examines community members' perceptions of voice function following laryngeal cancer management compared to ratings by clinicians and patients.

METHOD

Sixty-six (Tis-T3) laryngeal cancer patients post-radiotherapy, 10 community members and three speech-language pathologists (clinicians) were recruited. Patients completed voice recordings and self-rated voice quality and acceptability, six months post-radiotherapy. Community members and clinicians rated patient voice recordings using (a) Voice Quality/Acceptability questionnaire, (b) Communicative Suitability Scale (voice function in different vocally demanding environments) and (c) a gender perception question.

RESULT

Ratings for voice quality differed significantly (p < 0.001) between community members and clinicians and approached significance (p= 0.08) between community members and patients. No significant difference for voice acceptability was noted between community members and clinicians/patients. Community members rated the irradiated voice significantly different (p ≤ 0.02) across communication environments with more vocally demanding environments being rated as "Barely Sufficient". Incorrect sex identification (gender perception) occurred with 25% of females.

CONCLUSION

Community communication partners identify functional voice impairments post-radiotherapy, particularly across more vocally demanding environments and for female speakers. Implications for voice rehabilitation including appropriate patient selection is highlighted.

Effect of voice rehabilitation training on the patients with laryngeal cancer after radiotherapy

This retrospective study examined the effect of voice rehabilitation training (VRT) for patients with laryngeal cancer (LC) after radiotherapy.Eighty-three eligible patients with LC were included. Forty-three patients were assigned to a treatment group, and underwent VRT, while the other 40 subjects were assigned to a control group, and were at waiting list. Primary outcome was measured by the Grade, Roughness, Breathiness, Asthenia, and Strain (GRBAS) scale. Secondary outcome was measured by Patient Perception Measures. All outcomes were measured before and 3 months after VRT intervention.Patients in the treatment group did not show better outcomes, measured by GRBAS scale (Grade, P = .78; Roughness, P = .61; Breathiness, P = .83; Ashenia, P = .89; and Strain, P = .41), and Patient Perception Measures (Vocal quality, P = .17; Acceptability, P = .35; Hoarseness, P = .23; Vocal fatigue, P = .39; and Ashamed, P = .51), compared with patients in the control group.The results of this study did not exert better outcomes in patients received VRT than those at waiting list.

Oncological and Functional Evaluation of Open Conservation Surgery for Hypopharyngeal Cancer with/without Reconstruction

Objectives

Oncological and functional results of open conservation surgery for hypopharyngeal cancer have been desired.

Methods

We performed a chart review of 33 patients with hypopharyngeal cancer who underwent open conservation surgery. Oncological and functional results were evaluated in surgery with primary closure (Group A) and surgery with reconstruction (Group B). Postoperative functions were evaluated by interval to resumption of oral intake, Functional Outcome Swallowing Scale (FOSS) and Communication Scale (CS).

Results

Five-year disease-specific and overall cumulative survival rates by Kaplan-Meier method for all cases were 95.7% and 82.3%, respectively. Duration from surgery to full oral intake was 12 days in Group A and 14 days in Group B. FOSS rates were 83.3 in Group A and 95.5 in Group B. CS was 0 in both groups.

Conclusion

Oncological and functional results of open conservation surgery were comparable to those with transoral surgery and chemo/radiotherapy. Our technique represents a reliable treatment for hypopharyngeal cancer.

Use of Larynx-Preservation Strategies in the Treatment of Laryngeal Cancer: American Society of Clinical Oncology Clinical Practice Guideline Update

Purpose To update the guideline recommendations on the use of larynx-preservation strategies in the treatment of laryngeal cancer. Methods An Expert Panel updated the systematic review of the literature for the period from January 2005 to May 2017. Results The panel confirmed that the use of a larynx-preservation approach for appropriately selected patients does not compromise survival. No larynx-preservation approach offered a survival advantage compared with total laryngectomy and adjuvant therapy as indicated. Changes were supported for the use of endoscopic surgical resection in patients with limited disease (T1, T2) and for initial total laryngectomy in patients with T4a disease or with severe pretreatment laryngeal dysfunction. New recommendations for positron emission tomography imaging for the evaluation of regional nodes after treatment and best measures for evaluating voice and swallowing function were added. Recommendations Patients with T1, T2 laryngeal cancer should be treated initially with intent to preserve the larynx by using endoscopic resection or radiation therapy, with either leading to similar outcomes. For patients with locally advanced (T3, T4) disease, organ-preservation surgery, combined chemotherapy and radiation, or radiation alone offer the potential for larynx preservation without compromising overall survival. For selected patients with extensive T3 or large T4a lesions and/or poor pretreatment laryngeal function, better survival rates and quality of life may be achieved with total laryngectomy. Patients with clinically involved regional cervical nodes (N+) who have a complete clinical and radiologic imaging response after chemoradiation do not require elective neck dissection. All patients should undergo a pretreatment baseline assessment of voice and swallowing function and receive counseling with regard to the potential impact of treatment options on voice, swallowing, and quality of life.

Costs from a healthcare and societal perspective among cancer patients after total laryngectomy: are they related to patient activation?

Purpose

The aim of this study is to investigate the associations between patient activation and total costs in cancer patients treated with total laryngectomy (TL).

Methods

All members of the Dutch Patients’ Association for Laryngectomees were asked to participate in this cross-sectional study. TL patients who wanted to participate were asked to complete a survey. Costs were measured using the medical consumption and productivity cost questionnaire and patient activation using the Patient Activation Measure (PAM). Sociodemographic and clinical characteristics were self-reported, and health status measured using the EQ-5D. The difference in total costs from a healthcare and societal perspective among four groups with different PAM levels were compared using (multiple) regression analyses (5000 bootstrap replications).

Results

In total, 248 TL patients participated. Patients with a higher (better) PAM (levels 2, 3, and 4) had a probability of 70, 80, and 93% that total costs from a healthcare perspective were lower than in patients with the lowest PAM level (difference €−375 to €−936). From a societal perspective, this was 73, 87, and 82% (difference €−468 to €−719). After adjustment for time since TL, education, and sex, the probability that total costs were lower in patients with a higher PAM level compared to patients with the lowest PAM level changed to 62–91% (healthcare) and 63–92% (societal). After additional adjustment for health status, the probability to be less costly changed to 35–71% (healthcare) and 31–48% (societal).

Conclusions

A better patient activation is likely to be associated with lower total costs from a healthcare and societal perspective.

Voice rehabilitation after laryngeal cancer: Associated effects on psychological well-being

Purpose

Psychological distress after laryngeal cancer treatment is prevalent. Although voice rehabilitation has shown to improve functional outcomes and positively affect health-related quality of life, to date, there has been limited study of the associated effect of behavioural voice intervention on psychological well-being/distress post laryngeal cancer.

Method

Sixty-three patients with Tis-T4 laryngeal cancer treated with (chemo)radiotherapy were prospectively recruited and randomised to either a voice rehabilitation (VR, n = 31) or control group (n = 32). The VR group received 10 speech pathology sessions consisting of both direct and indirect voice intervention post (chemo)radiotherapy. The control group received general voice education but not specific intervention. As part of a multidisciplinary assessment battery, psychological well-being/distress was measured using the Hospital Anxiety and Depression Scale (HADS) pre, six and 12 months post VR.

Results

Within-group analysis revealed a significant (p = 0.03) reduction in the proportion of patients with anxiety in the VR group between baseline and 12 months. No change over time was observed in controls. Between-group analysis revealed a trend for fewer VR cases demonstrating anxiety (p = 0.06) or depression (p = 0.08) at 6 months and significantly fewer demonstrating anxiety (p = 0.04) and depression (p = 0.04) at 12 months, compared to controls. Significant correlations were observed between patients’ voice perceptions and reduced anxiety (r_pb = −0.38) and depression (r_pb = −0.66) within the VR group at 12 months.

Conclusions

The positive correlations and between-group analyses indicate a positive effect on psychological well-being associated with completing voice rehabilitation. Results highlight potential additional benefits of behavioural voice intervention beyond achieving direct change to voice function.

Evidence and evidence gaps of laryngeal cancer surgery

Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number or organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery, and transoral robotic surgery have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures. In addition to an improvement of prognosis, in recent years the preservation of function and maintenance of life quality after primary therapy of laryngeal cancer has increasingly become the focus of therapy planning. Significant late toxicity after chemoradiation has been identified as an important issue. This leads to a reassessment of surgical concepts and initiation of studies on laryngeal cancer surgery which was additionally stimulated by the advent of transoral robotic surgery in the US. Improving the evidence base of laryngeal cancer surgery by successful establishment of surgical trials should be the future goal.

Effectiveness and cost-utility of a guided self-help exercise program for patients treated with total laryngectomy: protocol of a multi-center randomized controlled trial

BACKGROUND

Total laryngectomy with or without adjuvant (chemo)radiation often induces speech, swallowing and neck and shoulder problems. Speech, swallowing and shoulder exercises may prevent or diminish these problems. The aim of the present paper is to describe the study, which is designed to investigate the effectiveness and cost-utility of a guided self-help exercise program built into the application "In Tune without Cords" among patients treated with total laryngectomy.

METHODS/DESIGN

Patients, up to 5 years earlier treated with total laryngectomy with or without (chemo)radiation will be recruited for participation in this study. Patients willing to participate will be randomized to the intervention or control group (1:1). Patients in the intervention group will be provided access to a guided self-help exercise program and a self-care education program built into the application "In Tune without Cords". Patients in the control group will only be provided access to the self-care education program. The primary outcome is the difference in swallowing quality (SWAL-QOL) between the intervention and control group. Secondary outcome measures address speech problems (SHI), shoulder disability (SDQ), quality of life (EORTC QLQ-C30, QLQ-H&N35 and EQ-5D), direct and indirect costs (adjusted iMCQ and iPCQ measures) and self-management (PAM). Patients will be asked to complete these outcome measures at baseline, immediately after the intervention or control period (i.e. at 3 months follow-up) and at 6 months follow-up.

DISCUSSION

This randomized controlled trial will provide knowledge on the effectiveness of a guided self-help exercise program for patients treated with total laryngectomy. In addition, information on the value for money of such an exercise program will be provided. If this guided self-help program is (cost)effective for patients treated with total laryngectomy, the next step will be to implement this exercise program in current clinical practice.
