Survival and Prognostic Factors for Outcome after Radiotherapy for T2 Glottic Carcinoma.

BACKGROUND: Local recurrence after radiotherapy for T2 glottic carcinoma remains an issue and identifying patients at risk for relapse is, therefore, important. This study aimed to assess the oncological outcomes and prognostic factors in a consecutive series of patients treated with radiotherapy for T2N0 glottic carcinoma. METHODS: Patients with T2N0 glottic carcinoma treated with radiotherapy were included in this retrospective study. Five- and ten-year local control (LC), overall survival (OS), disease-specific survival (DSS), and laryngeal preservation (LP) rates were calculated with the Kaplan-Meier method. The impact of prognostic variables was evaluated with the log-rank test. RESULTS: Ninety-four patients were included for analysis. LC, OS, DSS, and LP rates were 70.5, 63.7, 86.0, and 74.7%, respectively at five years and 65.8, 41.0, 75.6, and 72.4% at 10 years. In total, 46 scans were included in the analyses. Vertical involvement of the anterior commissure on imaging showed a significant impact on LC. CONCLUSIONS: In accordance with previously described surgical risk factors, we identified vertical involvement of the anterior commissure on imaging as a prognostic factor for radiation failure.

Quality of life and voice outcome of patients treated with transoral CO2 laser microsurgery for early glottic carcinoma (T1-T2): a 2-year follow-up study.

PURPOSE: Longitudinal studies in laryngeal cancer can provide clinicians information about short-term and long-term functional outcomes, like quality of life (QoL) and voice outcome. This information is important when counseling patients or choosing a primary treatment modality. The present study assessed long-term (2 years) QoL and voice outcome in patients with extended T1 and limited T2 glottic carcinoma treated with transoral CO2 laser microsurgery (TLM) (unilateral type III or bilateral type II resections). METHODS: Three questionnaires were administered: the Voice Handicap Index (VHI), the European Organization for Research and Treatment of Cancer (EORTC) QoL questionnaire (QLQ)-C30, the EORTC QLQ-HN35. A perceptual voice evaluation at six different time points was conducted: preoperatively, and postoperatively at 6 weeks, 3 months, 6 months, 1 year, and 2 years. Fluctuations over time were investigated. RESULTS: Sixty-one patients were included in the analysis. Patients reported high-level functioning and low symptom scores 2 years postoperatively. Gender significantly affected the VHI scores at 2 years (mean VHI scores: female 8.7 vs. male, 23.9; p = 0.023). The major improvement in VHI scores was observed within the first 6 months. The tumor stage (T1a, T1b, and T2) significantly impacted the grade (mean scores at 2 years: 1.0, 1.9, and 1.7; p = 0.001). These scores stabilized at 6 months. CONCLUSIONS: Patients show good long-term QoL with low symptom scores, a low voice handicap, and mild to moderate dysphonia, 2 years postoperatively. Scores stabilize at 6 months and provide a clear indication of status at 1 and 2 years.

Voice outcome after unilateral ELS type III or bilateral type II resections for T1-T2 glottic carcinoma: Results after 1 year.

BACKGROUND: Voice outcome was assessed in patients with extended T1 and limited T2 glottic carcinoma, treated with a unilateral type III or a bilateral type II resection according to the European Laryngological Society (ELS) classification. METHODS: Objective evaluation (acoustic and aerodynamic parameters), perceptual evaluation (GRBAS), and patients' self-assessment (voice handicap index [VHI]) were performed before and 1 year after treatment. Results were evaluated according to ELS resection type and the involvement of the anterior commissure. RESULTS: The majority of voice parameters in all resection subgroups showed an improvement of the mean score 1 year postoperatively. Grade of dysphonia varied between 1.15 and 1.66 postoperatively and VHI score varied from 23.3 to 24.5. CONCLUSION: Voice outcome after ELS unilateral type III or a bilateral type II resection for extended T1 and limited T2 glottic carcinoma is good with mild to very moderate perceptive dysphonia and low self-reported voice impairment.

Variation in Integrated Head and Neck Cancer Care: Impact of Patient and Hospital Characteristics.

Background: Monitoring and effectively improving oncologic integrated care requires dashboard information based on quality registrations. The dashboard includes evidence-based quality indicators (QIs) that measure quality of care. This study aimed to assess the quality of current integrated head and neck cancer care with QIs, the variation between Dutch hospitals, and the influence of patient and hospital characteristics. Methods: Previously, 39 QIs were developed with input from medical specialists, allied health professionals, and patients' perspectives. QI scores were calculated with data from 1,667 curatively treated patients in 8 hospitals. QIs with a sample size of >400 patients were included to calculate reliable QI scores. We used multilevel analysis to explain the variation. Results: Current care varied from 29% for the QI about a case manager being present to discuss the treatment plan to 100% for the QI about the availability of a treatment plan. Variation between hospitals was small for the QI about patients discussed in multidisciplinary team meetings (adherence: 95%, range 88%-98%), but large for the QI about malnutrition screening (adherence: 50%, range 2%-100%). Higher QI scores were associated with lower performance status, advanced tumor stage, and tumor in the oral cavity or oropharynx at the patient level, and with more curatively treated patients (volume) at hospital level. Conclusions: Although the quality registration was only recently launched, it already visualizes hospital variation in current care. Four determinants were found to be influential: tumor stage, performance status, tumor site, and volume. More data are needed to assure stable results for use in quality improvement.

Evaluation of surgical margin status in patients with early glottic cancer (Tis-T2) treated with transoral CO2 laser microsurgery, on local control.

PURPOSE: To assess the impact of surgical margins status on local control in patients with primary early glottic (Tis-T2) squamous cell carcinoma after treatment with transoral CO2 laser microsurgery (TLM) and to assess the significance of additional wound bed biopsies. METHODS: Patients with Tis-T2 tumours treated with TLM type I-III resections according to the European Laryngological Society classification between 2009 and 2013 were included in retrospective analysis. Recurrence rate was determined in patients with free versus non-free specimen margins and wound biopsies. Five-year survival rates were determined using the Kaplan-Meier method. Prognostic impact of pT-category, resection margin status, tumour differentiation, wound bed biopsy status, and number of biopsies on local control (LC) were tested with the log-rank test. RESULTS: Eighty-four patients were included in the analysis. Positive margins were seen in 68 patients (81.0%). Margin status after TLM did not significantly influence LC (p = 0.489), however, additional wound bed biopsies were significantly associated with lower LC (p = 0.009). Five-year LC, disease-specific survival, overall survival and laryngeal preservation were 78.6, 78.0, 98.6 and 100%, respectively. CONCLUSIONS: Additional wound bed biopsies can help predict local recurrence in patients treated with TLM for early glottic carcinoma. We propose that there is enough evidence to support a wait-and-see policy in patients with positive specimen margins and negative wound bed biopsies. For patients with positive wound bed biopsies, further treatment is warranted.

Treatment Preferences in Patients With Early Glottic Cancer.

OBJECTIVE: For early glottic carcinoma, the 2 main treatment modalities are radiotherapy (RT) and transoral CO2 laser microsurgery (TLM). The aim of this study was to investigate treatment preferences and considerations in patients with early glottic carcinoma (T1-T2) who were given a choice between TLM and RT. SUBJECTS AND METHODS: Patients with early glottic cancer (suspected or confirmed extended T1 or limited T2) were counseled by an ENT-surgeon. A subset of 32 patients was also counseled by a radiotherapist. Treatment choice and considerations were recorded and analyzed. RESULTS: Of 175 patients, 168 patients (96%) chose TLM, and 7 patients (4%) chose RT. The most common reason for choosing TLM was shorter treatment and more treatment options in case of recurrence. Subanalysis showed that additional counseling by the radiotherapist did not seem to affect our patients' preferences for TLM in this group. CONCLUSIONS: The majority of patients in our study prefer TLM to RT when given a choice. Reasons given indicate that optimizing future treatment options and practical considerations seemed more important to our patients than primary functional outcome. Further research is needed to study patient-related and physician-related factors to gain more insight into this complicated process of shared decision making.

Feedback preferences of patients, professionals and health insurers in integrated head and neck cancer care.

BACKGROUND: Audit and feedback on professional practice and health care outcomes are the most often used interventions to change behaviour of professionals and improve quality of health care. However, limited information is available regarding preferred feedback for patients, professionals and health insurers. OBJECTIVE: Investigate the (differences in) preferences of receiving feedback between stakeholders, using the Dutch Head and Neck Audit as an example. METHODS: A total of 37 patients, medical specialists, allied health professionals and health insurers were interviewed using semi-structured interviews. Questions focussed on: "Why," "On what aspects" and "How" do you prefer to receive feedback on professional practice and health care outcomes? RESULTS: All stakeholders mentioned that feedback can improve health care by creating awareness, enabling self-reflection and reflection on peers or colleagues, and by benchmarking to others. Patients prefer feedback on the actual professional practice that matches the health care received, whereas medical specialists and health insurers are interested mainly in health care outcomes. All stakeholders largely prefer a bar graph. Patients prefer a pie chart for patient-reported outcomes and experiences, while Kaplan-Meier survival curves are preferred by medical specialists. Feedback should be simple with firstly an overview, and 1-4 times a year sent by e-mail. Finally, patients and health professionals are cautious with regard to transparency of audit data. CONCLUSIONS: This exploratory study shows how feedback preferences differ between stakeholders. Therefore, tailored reports are recommended. Using this information, effects of audit and feedback can be improved by adapting the feedback format and contents to the preferences of stakeholders.

Long-term Outcome After Survival of a Cardiac Arrest: A Prospective Longitudinal Cohort Study.

BACKGROUND: A cardiac arrest can lead to hypoxic brain injury, which can affect all levels of functioning. OBJECTIVE: To investigate 1-year outcome and the pattern of recovery after surviving a cardiac arrest. METHODS: This was a multicenter, prospective longitudinal cohort study with 1 year of follow-up (measurements 2 weeks, 3 months, 1 year). On function level, physical/cardiac function (New York Heart Association Classification), cognition (Cognitive Log [Cog-log], Cognitive Failures Questionnaire), emotional functioning (Hospital Anxiety and Depression Scale, Impact of Event Scale), and fatigue (Fatigue Severity Scale) were assessed. In addition, level of activities (Frenchay Activities Index, FAI), participation (Community Integration Questionnaire [CIQ] and return to work), and quality of life (EuroQol 5D, EuroQol Visual Analogue Scale, SF-36, Quality of Life after Brain Injury) were measured. RESULTS: In this cohort, 141 cardiac arrest survivors were included. At 1 year, 14 (13%) survivors scored below cutoff on the Cog-log. Both anxiety and depression were present in 16 (15%) survivors, 29 (28%) experienced posttraumatic stress symptoms and 55 (52%), severe fatigue. Scores on the FAI and the CIQ were, on average, respectively 96% and 92% of the prearrest scores. Of those previously working, 41 (72%) had returned to work. Most recovery of cognitive function and quality of life occurred within the first 3 months, with further improvement on some domains of quality of life up to 12 months. CONCLUSIONS: Overall, long-term outcome in terms of activities, participation, and quality of life after cardiac arrest is reassuring. Nevertheless, fatigue is common; problems with cognition and emotions occur; and return to work can be at risk.

Utility approach to decision-making in extended T1 and limited T2 glottic carcinoma.

BACKGROUND: It is still undecided if endoscopic laser surgery or radiotherapy is the preferable treatment in extended T1 and limited T2 glottic tumors. Health utilities assessed from patients can aid in decision-making. METHODS: Patients treated for extended T1 or limited T2 glottic carcinoma by laser surgery (n = 12) or radiotherapy (n = 14) assigned health utilities using a visual analog scale (VAS), time tradeoff (TTO) technique and scored their voice handicap using the Voice Handicap Index (VHI). RESULTS: VAS and TTO scores were slightly lower for the laser group compared to the radiotherapy group, however, not significantly so. The VHI showed a correlation with the VAS score, which was very low in both groups and can be considered (near) normal. CONCLUSION: Patients show no clear preference for the outcomes of laser surgery or radiotherapy from a quality of life (QOL) or voice handicap point of view. These data can now be incorporated into decision-making models. © 2017 Wiley Periodicals, Inc. Head Neck, 2017 © 2016 Wiley Periodicals, Inc. Head Neck 39: 779-785, 2017.

Resection margins in oral cancer surgery: Room for improvement.

The purpose of this review was to identify publications on resection margins in oral cancer surgery and compare these with the results from 2 Dutch academic medical centers. Eight publications were considered relevant for this study, reporting 30% to 65% inadequate resection margins (ie, positive and close margins), compared to 85% in Dutch centers. However, clinical outcome in terms of overall survival and recurrence seemed comparable. The misleading difference is caused by lack of unanimous margin definition and differences in surgicopathological approaches. This prevents comparison between the centers. Data from Dutch centers showed that inadequate resection margins have a significantly negative effect on local recurrence, regional recurrence, distant metastasis, and overall survival. These results confirm the need for improvement in oral cancer surgery. We underline the need for consistent protocols and optimization of frozen section procedures. We comment on development of optical techniques for intraoperative assessment of resection margins. © 2015 Wiley Periodicals, Inc. Head Neck 38: E2197-E2203, 2016.

Early neurologically-focused follow-up after cardiac arrest improves quality of life at one year: A randomised controlled trial.

BACKGROUND: Survivors of a cardiac arrest frequently have cognitive and emotional problems and their quality of life is at risk. We developed a brief nursing intervention to detect cognitive and emotional problems, provide information and support, promote self-management, and refer them to specialised care if necessary. This study examined its effectiveness. METHODS: Multicentre randomised controlled trial with measurements at two weeks, three months and twelve months after cardiac arrest. 185 adult cardiac arrest survivors and 155 caregivers participated. Primary outcome measures were societal participation and quality of life of the survivors at one year. Secondary outcomes were the patient's cognitive functioning, emotional state, extended daily activities and return to work, and the caregiver's well-being. Data were analysed using 'intention to treat' linear mixed model analyses. RESULTS: After one year, patients in the intervention group had a significantly better quality of life on SF-36 domains Role Emotional (estimated mean differences (EMD)=16.38, p=0.006), Mental Health (EMD=6.87, p=0.003) and General Health (EMD=8.07, p=0.010), but there was no significant difference with regard to societal participation. On the secondary outcome measures, survivors scored significantly better on overall emotional state (HADS total, EMD=-3.25, p=0.002) and anxiety (HADS anxiety, EMD=-1.79, p=0.001) at one year. Furthermore, at three months more people were back at work (50% versus 21%, p=0.006). No significant differences were found for caregiver outcomes. CONCLUSION: The outcomes of cardiac arrest survivors can be improved by an intervention focused on detecting and managing the cognitive and emotional consequences of a cardiac arrest. TRIAL REGISTRATION: Current controlled trials, ISRCTN74835019.

[Cardiac troponin]. / Cardiaal troponine.

Measurement of cardiac troponins (cTnT and cTnI), the only cardiac specific biomarkers available, is the gold standard in diagnosing acute coronary syndrome. Due to the recent introduction of more sensitive methods i.e. the high-sensitivity troponin assays, the diagnostic cut-off concentrations have very recently been established. We describe two male patients who presented at the emergency department with acute chest pain, but in whom clear evidence for a myocardial infarction in the ST segment of the EKG was lacking. Case 1 illustrates that such assays enable the earlier diagnosis of acute myocardial infarction. Case 2 shows that the diagnosis of acute myocardial infarction should be accompanied by a typical rise or fall of troponin concentrations. The latest insights into high-sensitivity cardiac troponin assays are discussed in this article. We focus specifically on sensitivity and specificity, reference values obtained from a healthy control group, and the reference change value required to detect acute myocardial infarction.

Phenotypes and genetic architecture of focal primary torsion dystonia.

BACKGROUND: The focal primary torsion dystonias (FPTDs) form a group of clinical heterogeneous syndromes and can be considered a genetic complex disease; it is thought to be primed by genetic variants with variable impact and triggered by non-genetic factors. Thorough clinical description of FPTDs cohorts is sparse but essential for further progress in genetic research. OBJECTIVE: To establish suggested relations between age at onset (AaO), site and family history in a large focal dystonias cohort and gain more insight into familial clustering for genetic research. PATIENTS AND METHODS: A prospective cohort study between March 2008 and March 2011, including 676 FPTD patients attending the botulinum toxin outpatient clinics of six Dutch movement disorder centres. RESULTS AND CONCLUSIONS: Of all of the FPTD patients, 25% had a familial predisposition; in 2.4% a Mendelian inheritance pattern was noted. With a stronger family history, a significantly lower AaO was seen in all focal dystonias. In both the sporadic and familial focal dystonia groups, AaO had an effect on the distribution of dystonia, with a caudal to cranial tendency. In all focal dystonia forms, women were more frequently affected, except for writer's cramp. Careful clinical characterisation will allow the formation of phenotype subgroups. We suggest that genetic research into FPTDs will benefit from this approach and discuss genetic research strategies to decipher the complex background of focal dystonias.

Functional outcomes after radiotherapy or laser surgery in early glottic carcinoma: a systematic review.

BACKGROUND: Early glottic carcinoma is treated with laser surgery or radiotherapy, but which treatment has better functional outcomes is unclear. This systematic review compared functional outcomes (voice, swallowing, quality of life [QOL]) in more extended T1a and limited T2 tumors (1) between treatments and (2) between greater and lesser laser resections. METHODS: A systematic literature search covered relevant databases from 1990 to 2009, combining all patient/problem, intervention, comparison, outcome (PICO) keyword variations. RESULTS: A total of 19 papers met the inclusion criteria, all of which were level IV evidence. Papers reported only voice and QOL. Heterogeneity of outcome measures prevented data pooling. Uncertainty about tumor comparability (depth, extent) between the 2 treatments, small subject numbers, and poor-quality reporting hindered interpretation. CONCLUSIONS: To allow comparison of laser surgery versus radiotherapy, a standardized method is needed that accurately measures tumor extent and depth. Agreement on functional outcome measures is necessary to allow comparison of treatments and resection types. Multicenter studies should be encouraged to guarantee adequate subject numbers.

Prognosis: a variable parameter: dynamic prognostic modeling in head and neck squamous cell carcinoma.

BACKGROUND: In general, the estimated prognosis of patients with cancer is based on patient characteristics known at the time of diagnosis and presented as if a lifetime verdict. However, the prognosis of patients with cancer who survive the first critical years changes, along with the prognosis for those with local or regional recurrences or distant metastases. METHODS: This study concerns 2927 patients with a primary head and neck squamous cell carcinoma (HNSCC). We developed prognostic models after initial treatment and at different time points during follow-up. RESULTS: The developed models show the effects of survival time, recurrences, and distant metastasis during follow-up. The C-statistics ranged from 0.76 to 0.69. CONCLUSION: Prognosis is dynamic: the passage of time and the occurrence of life events change the predicted probabilities of survival. The models enhance our insight in the effect of recurrences and metastasis during follow-up and could be used for better patient counseling.

A patient-centred interdisciplinary palliative care programme for end-stage chronic respiratory diseases.

Palliative care should be part of integrated care for patients with end-stage respiratory diseases. An intensive inpatient interdisciplinary palliative care programme has been developed for patients with end-stage respiratory diseases in the Netherlands. This programme consists of the management of daily symptoms and care needs to support patients and their families, and maintain or improve quality of life of these patients and their loved ones. This article presents case studies which describe the clinical course and management of three patients admitted to the programme: a 77-year-old woman who died from chronic obstructive pulmonary disease (COPD); a 60-year-old woman with end-stage COPD who improved her daily functioning and was discharged home after 3 months; and a 74-year-old woman who died of pulmonary fibrosis. This article describes the characteristics of the programme and shows the possible benefits of an intensive patient-centred interdisciplinary palliative care programme for patients with end-stage respiratory diseases. Palliative care programmes can be the final step in the chain of care for patients with respiratory diseases. Further research is necessary to study whether, and to what extent, a patient-centred interdisciplinary palliative care programme for end-stage respiratory diseases may improve health status, daily symptom burden, patient satisfaction and quality of dying.

Model-assisted predictions on prognosis in HNSCC: do we learn?

Dedicated software packages incorporating prognostic models are meant to aid physicians in making accurate predictions of prognosis. This study concerns 742 predictions of 5-year survival on consecutive newly diagnosed patients with head- and neck squamous cell carcinoma. The 5-year survival predictions made by the physicians are not compared with actual survival, but with a prediction made by OncologIQ, a dedicated software package. We used a linear regression and a linear mixed-effects model to look at absolute differences between both predictions and possible learning effects. Predictions made by the physicians were optimistic and inaccurate. Using the linear regression and linear mixed-effects models, the physicians' learning effect showed little improvement per successive prediction. We conclude that prognostic predictions in general are imprecise. When given feedback on the model's predicted survival, the accuracy increases, but only very modestly.

Conditional relative survival in head and neck squamous cell carcinoma: Permanent excess mortality risk for long-term survivors.

BACKGROUND: Dynamic predictions on head and neck cancer survival could offer, besides improved patient counseling, insight into long-term effects of tumor- and patient-based characteristics on survival. Theoretically, there could be a certain time period after diagnosis after which the patient returns to a population risk on survival. METHODS: In all, 7255 patients with a primary head and neck squamous cell carcinoma (HNSCC) aged 25 to 90 years, diagnosed between January 1980 and January 2004 in The Netherlands, were included. Conditional 5-year relative survival for every additional year survived was computed. RESULTS: The overall conditional relative prognosis reached a plateau after approximately 4 years; a permanent 20% to 25% excess mortality for long-term HNSCC survivors remained. CONCLUSIONS: Conditional 5-year relative survival for patients with HNSCC remains poorer compared to age- and sex-matched counterparts in the general population, even when alive at 15 years after diagnosis. We assume that this is caused by an excess comorbidity in these patients, mainly due to smoking and alcohol abuse.

Illness cognitions in head and neck squamous cell carcinoma: predicting quality of life outcome.

GOALS OF WORK: This paper presents an observational study of the longitudinal effects of cancer treatment on quality of life (QoL) in patients treated for head and neck squamous cell carcinoma (HNSCC), and evaluated the contribution of patients' baseline illness cognitions to the prediction of QoL 2 years after diagnosis. PATIENTS AND METHODS: One hundred seventy-seven patients eligible for primary treatment for HNSCC completed the Illness Perception Questionnaire-Revised at baseline and the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire-30 at baseline, at 1-year and 2-year follow-ups. MAIN RESULTS: Compared to baseline, patients reported better emotional functioning at both follow-ups (p < 0.001), worse social functioning at 12 months (p < 0.05), and better global health status at 24 months (p < 0.05). Patients' own implicit common sense beliefs about their illness added small but significant amounts of variance to the prediction of QoL after 2 years. Less belief in own behavior causing the illness predicted better functioning and better global health. Strong illness identity beliefs predicted worse functioning and worse global health. Negative perceptions about the duration of the illness (chronic timeline beliefs) and more negative perceived consequences also predicted worse QoL. CONCLUSIONS: Our results on the negative perceptions about the duration of the illness, perceived consequences, and high symptom awareness predicting worse QoL illustrate the detrimental effects of uncertainty and negative expectations about the future course of the illness. The identification of these cognitive factors provides possible targets for counseling strategies to assist patients in long-term adjustment to HNSCC.
