    Head and neck cancer Radiotherapy s u m m a r y Background and aims: We performed a systematic review to examine the effect of nutritional interventions on nutritional status, quality of life (QoL) and mortality in patients with head and neck squamous cell cancer (HNSCC) receiving radiotherapy or chemoradiotherapy. Methods: We searched Pubmed, EMBASE, CENTRAL and Cinahl from inception through January 3rd, 2012 to identify randomized controlled trials (RCTs) from a broad range of nutritional interventions in patients with HNSCC during (chemo)radiotherapy. Two reviewers independently assessed study eligibility and risk of bias, and extracted data. Results: Of 1141 titles identified, 12 study reports were finally included, describing 10 different studies with 11 interventions. Four out of 10 studies examined the effects of individualized dietary counseling, and showed significant benefits on nutritional status and QOL compared to no counseling or general nutritional advice by a nurse (p < 0.05). Three studies on oral nutritional supplements (ONS) were inconsistent about the effect on nutritional status compared with no supplementation. One study showed that nasogastric tube feeding had beneficial effects on nutritional status compared to ONS, but not in all patient groups (p < 0.04). One study showed benefits of percutaneous endoscopic gastronomy (PEG) feeding on nutritional status shortly after RT compared with nasogastric feeding (p ¼ 0.001). Two studies showed that prophylactic PEG feeding was not superior over tube feeding if required. Conclusions: This review shows beneficial effects of individualized dietary counseling on nutritional status and QoL, compared to no counseling or standard nutritional advice. Effects of ONS and tube feeding were inconsistent

    Objective: To investigate the effectiveness of a guided self-help exercise program on swallowing, speech, and shoulder problems in patients treated with total laryngectomy (TL). Materials and methods: This randomized controlled trial included patients treated with TL in the last 5 years. Patients were randomized into the intervention group (self-help exercise program with flexibility, range-of-motion and lymphedema exercises and self-care education program) or control group (self-care education program). Both groups completed measurements before and 3 and 6-months after randomization. The primary outcome was swallowing problems (SWAL-QOL). Secondary outcomes were speech problems (SHI), shoulder problems (SDQ), self-management (patient activation: PAM) and health-related quality of life (HRQOL: EORTC QLQ-C30/H&N35). Adherence was defined as moderate-high in case a patient exercised >1 per day. Linear mixed model analyses were conducted to investigate the effectiveness of the intervention and to investigate whether neck dissection, treatment indication (primary/salvage TL), time since treatment, severity of problems, and preferred format (online/booklet) moderated the effectiveness. Results: Moderate-high adherence to the exercise program was 59%. The intervention group (n = 46) reported less swallowing and communication problems over time compared to the control group (n = 46) (p-value = 0.013 and 0.004). No difference was found on speech, shoulder problems, patient activation and HRQOL. Time since treatment moderated the effectiveness on speech problems (p-value = 0.025): patients within 6 months after surgery benefitted most from the intervention. Being treated with a neck dissection, treatment indication, severity of problems and format did not moderate the effectiveness. Conclusion: The guided self-help exercise program improves swallowing and communication. Trial registration. NTR5255

    The development of a decision aid for patients with operable oropharyngeal carcinoma in the Netherlands - A mixed methods study

    Get PDF
    OBJECTIVE: The aim of this project is to create an interactive online patient decision aid (PDA) for oropharyngeal cancer (OPSCC) patients, eligible for transoral (robotic) surgery with an ultimate goal to assist both physicians and patients in making treatment choices. MATERIALS AND METHODS: Following the International Patient Decision Aid Standards, a mixed-methods approach was employed. The study involved semi-structured in-depth interviews with patients and physicians, thinking-out-loud sessions, and study-specific questionnaires. Thematic coding and analysis were conducted on verbatim transcriptions of audio-recorded interviews. RESULTS: The PDA drafts were evaluated by twenty OPSCC survivors and twenty multidisciplinary specialists. Significant revisions were made after phase 1 to enhance readability and reduce text, whilst incorporating videos and graphics. Following all phases, both patients and specialists rated the PDA as comprehensible, feasible, and a valuable addition to regular counseling. CONCLUSION: This study showcases the development of a PDA for early stage oropharyngeal cancer patients considering surgery and radiotherapy options. The decision aid emphasizes the disparities in short- and long-term side effects between the two treatments. Patients and physicians found the decision aid to be understandable, user-friendly, and helpful for future patients. The PDA is available on https://beslissamen.nl/

    Role of eHealth application Oncokompas in supporting self-management of symptoms and health-related quality of life in cancer survivors:a randomised, controlled trial

    Background Knowledge about the efficacy of behavioural intervention technologies that can be used by cancer survivors independently from a health-care provider is scarce. We aimed to assess the efficacy, reach, and usage of Oncokompas, a web-based eHealth application that supports survivors in self-management by monitoring health-related quality of life (HRQOL) and cancer-generic and tumour-specific symptoms and obtaining tailored feedback with a personalised overview of supportive care options. Methods In this non-blinded, randomised, controlled trial, we recruited patients treated at 14 hospitals in the Netherlands for head and neck cancer, colorectal cancer, breast cancer, Hodgkin lymphoma, or non-Hodgkin lymphoma. Adult survivors (aged ≥18 years) were recruited through the Netherlands Cancer Registry (NCR) and invited by their treating physician through the Patient Reported Outcomes Following Initial Treatment and Long term Evaluation of Survivorship (PROFILES) registry. Participants were randomly assigned (1:1) by an independent researcher to the intervention group (access to Oncokompas) or control group (access to Oncokompas after 6 months), by use of block randomisation (block length of 68), stratified by tumour type. The primary outcome was patient activation (knowledge, skills, and confidence for self-management), assessed at baseline, post-intervention, and 3-month and 6-month follow-up. Linear mixed models (intention-to-treat) were used to assess group differences over time from baseline to 6-month follow-up. The trial is registered in the Netherlands Trial Register, NTR5774 and is completed. Findings Between Oct 12, 2016, and May 24, 2018, 625 (21%) of 2953 survivors assessed for eligibility were recruited and randomly assigned to the intervention (320) or control group (305). Median follow-up was 6 months (IQR 6−6). Patient activation was not significantly different between intervention and control group over time (difference at 6-month follow-up 1·7 [95% CI −0·8–4·1], p=0·41). Interpretation Oncokompas did not improve the amount of knowledge, skills, and confidence for self-management in cancer survivors. This study contributes to the evidence for the development of tailored strategies for development and implementation of behavioural intervention technologies among cancer survivors

    Downsizing of voice prosthesis diameter in patients with laryngectomy - An in vitro study

    In patients with laryngectomy, voice prostheses inserted into a tracheoesophageal fistula (TEF) are widely used for vocal rehabilitation. Gradual dilation of the TEF may cause bothersome leakage around voice prostheses. Pros thesis-related weight and mechanical trauma possibly exacerbate TEF dilation. If prosthesis size were to be decreased, with a concomitant decrease in prosthesis weight and diameter, dilation of the TEF would probably lessen. We performed in vitro tests to study the effects on aerodynamic prosthesis function when the prosthesis size-in particular, the inner diameter-was decreased. The effects on airflow and pressure were specifically studied in the airflow range of patients with laryngectomy. A 1-mm decrease of the regular inner prosthesis diameter from 5 mm to 4 mm showed no significant aerodynamic consequences at the average laryngectomized airflow point. Also, such a 1-mm decrease in diameter involved a prosthesis weight reduction of 18%. In view of these findings, downsizing the standard prosthetic diameter should be considered in future voice prosthesis developmen

    Management of the brachial plexus in head and neck cancer

    No full text
    Purpose of reviewThe brachial plexus is an important anatomical structure that is regularly encountered by head and neck surgeons and radiation oncologists. Surgical or radiation-induced brachial plexus injury have great impact on arm function and quality of life. Anatomical variations and management of the brachial plexus in head and neck cancer treatment are discussed.Recent findingsThe brachial plexus consists of spinal roots from C5-C8 and T1. The most prevalent anatomical variations in brachial plexus anatomy include the prefixed brachial plexus (additional contribution from C4) in 11%, the roots of C5 and C6 piercing the belly of the anterior scalene muscle in 6.8%, and presence of the scalenus minimus muscle in 4.1-46%. Due to its location, the brachial plexus is at risk of inadvertent division or neuropraxia during surgical procedures such as neck dissection or robot-assisted transaxillary thyroid surgery (RATS). In case of inadvertent division, nerve reconstruction surgery is warranted and may lead to improved function. The risk of radiation-induced brachial plexus injury is dose-dependent and occurs in approximately 12-22%. Currently, no successful treatment options exist for radiation-induced injury.SummaryKnowledge of anatomical variations is important for head and neck surgeons to minimize the risk of brachial plexus injury. Limiting radiation therapy dose to the brachial plexus is desirable to decrease the risk of brachial plexus injury

    The influence of closure technique in total laryngectomy on the development of a pseudo-diverticulum and dysphagia

    OBJECTIVE: In total laryngectomy, the neopharynx can be closed in several ways. It is suggested that a pseudo-diverticulum is seen more frequently in patients closed with vertical closure than with "T"-shaped closure, causing postoperative dysphagia. We report the results of patients treated with vertical closure and "T"-shaped closure with regard to the formation of a pseudo-diverticulum and postoperative dysphagia. METHODS: In our retrospective cohort study, we identified 117 consecutive laryngectomized patients treated in the VU University Medical Center of Amsterdam between March 2009 and December 2013. Evaluations with statistical analysis of postoperative outcome measures (the formation of a pseudo-diverticulum and dysphagia), qualitative and quantitative variables were conducted. RESULTS: Patient demographics were similar between the vertical-shaped closure and the "T"-shaped closure groups. In 84.6% of patients with vertical closure, a pseudo-diverticulum was seen compared to 18.5% with "T"-shaped closure (p < 0.001). Dysphagia was increasingly seen in patients with a pseudo-diverticulum (60.5%) compared to patients without a pseudo-diverticulum (39.5%) (p = 0.090). CONCLUSION: Formation of a pseudo-diverticulum is more frequently seen in laryngectomy patients closed with vertical closure than in patients closed with "T"-shaped closure of the neopharynx. It is favorable to implement "T"-shaped closure in laryngectomy

    Aerodynamic and sound intensity measurements in tracheoesophageal voice

    BACKGROUND: In laryngectomized patients, tracheoesophageal voice generally provides a better voice quality than esophageal voice. Understanding the aerodynamics of voice production in patients with a voice prosthesis is important for optimizing prosthetic designs and successful voice rehabilitation. OBJECTIVES: To measure the aerodynamics and sound intensity in tracheoesophageal voice production. STUDY DESIGN AND METHODS: We built a special setup, which consisted of a Pentium 200 MHz computer with an AD-DA interface card and Labview 4.01 software. In an oral/nasal mask we constructed several mass flow sensors and a microphone. This measured both the oral airflow and the level of sound. For the measurement of endotracheal pressure, which is the driving force behind the airflow, we used a transducer which was connected to the tracheostoma. The endoesophageal pressure was measured at the level of the prosthesis in the esophagus by a Mikrotip transducer. Using this we could determine how much the voice prosthesis contributes to the overall pressure drop of the phonatory tract. Furthermore, the average airflow rate as a function of the sound pressure levels could be determined. RESULTS: In our population, 6 out of 7 patients showed a positive relationship between trans-source airflow and generated sound intensity. We compared our prosthesis pressure drop values with in vitro data and found that there are some differences, possibly due to difference in age of the prosthesis and physiological circumstances in vivo. The overall contribution of the voice prosthesis to the airway resistance depends on the level of phonation and the type of device. In our patient group it is apparent that the pharyngoesophageal (PE) segment has the greatest share of the total pressure drop, especially at higher airflow rates. We measured a 27% pressure drop in airflow over the voice prosthesis. Different tracheostoma occlusion methods did not have any effect on the aerodynamics and sound intensity. One patient that had had a jejunal graft for reconstruction showed, not unexpectedly, extremely different aerodynamic values. We were unable to define optimal airflow rates or optimal resistance values for sound production in the PE segment. CONCLUSION: The aerodynamic characteristics of voice production in laryngectomized patients with voice prostheses are determined by both prosthetic factors and PE segment tissue factors. In our patient group the PE segment is responsible for the greatest pressure drop. We found no significant difference in pressure drop and sound intensity for different tracheostoma occlusion method
