The course of health-related quality of life in the first 2 years after a diagnosis of head and neck cancer: the role of personal, clinical, psychological, physical, social, lifestyle, disease-related, and biological factors.

PURPOSE: The aim of this prospective cohort study was to estimate the relationship between the course of HRQOL in the first 2 years after diagnosis and treatment of head and neck cancer (HNC) and personal, clinical, psychological, physical, social, lifestyle, HNC-related, and biological factors. METHODS: Data were used from 638 HNC patients of the NETherlands QUality of life and BIomedical Cohort study (NET-QUBIC). Linear mixed models were used to investigate factors associated with the course of HRQOL (EORTC QLQ-C30 global quality of life (QL) and summary score (SumSc)) from baseline to 3, 6, 12, and 24 months after treatment. RESULTS: Baseline depressive symptoms, social contacts, and oral pain were significantly associated with the course of QL from baseline to 24 months. Tumor subsite and baseline social eating, stress (hyperarousal), coughing, feeling ill, and IL-10 were associated with the course of SumSc. Post-treatment social contacts and stress (avoidance) were significantly associated with the course of QL from 6 to 24 months, and social contacts and weight loss with the course of SumSc. The course of SumSc from 6 to 24 months was also significantly associated with a change in financial problems, speech problems, weight loss, and shoulder problems between baseline and 6 months. CONCLUSION: Baseline clinical, psychological, social, lifestyle, HNC-related, and biological factors are associated with the course of HRQOL from baseline to 24 months after treatment. Post-treatment social, lifestyle, and HNC-related factors are associated with the course of HRQOL from 6 to 24 months after treatment.

Intraoperative assessment of resection margins by Raman spectroscopy to guide oral cancer surgery.

Patients with oral cavity cancer are almost always treated with surgery. The goal is to remove the tumor with a margin of more than 5 mm of surrounding healthy tissue. Unfortunately, this is only achieved in about 15% to 26% of cases. Intraoperative assessment of tumor resection margins (IOARM) can dramatically improve surgical results. However, current methods are laborious, subjective, and logistically demanding. This hinders broad adoption of IOARM, to the detriment of patients. Here we present the development and validation of a high-wavenumber Raman spectroscopic technology, for quick and objective intraoperative measurement of resection margins on fresh specimens. It employs a thin fiber-optic needle probe, which is inserted into the tissue, to measure the distance between a resection surface and the tumor. A tissue classification model was developed to discriminate oral cavity squamous cell carcinoma (OCSCC) from healthy oral tissue, with a sensitivity of 0.85 and a specificity of 0.92. The tissue classification model was then used to develop a margin length prediction model, showing a mean difference between margin length predicted by Raman spectroscopy and histopathology of -0.17 mm.

Risk Factors For Hearing Decline From Childhood To Early Adolescence.

OBJECTIVE: To identify risk factors of hearing decline between 9 and 13 years of age. The risk factors examined included sociodemographic, health, and lifestyle-related factors. METHODS: This study was embedded within a population-based prospective cohort study from fetal life onwards in the Netherlands. Pure-tone audiometry and tympanometry were performed at the age of 9 and 13 years. The hearing decline was defined as an increase in low-frequency or high-frequency pure-tone average of at least 5 dB in one of both ears. Multivariable logistic regression was performed to examine the association of possible risk factors with hearing decline. The study was conducted from April 2012 to October 2015, and from April 2016 to September 2019. RESULTS: Of the 3,508 participants included, 7.8% demonstrated a hearing decline in the low frequencies, and 11.3% in the high frequencies. Participants who reported alcohol consumption were more likely to have a hearing decline in the low frequencies (OR 1.5, 95% CI 1.1; 2.0). Moreover, a lower educational level was associated with an increased odds of having a hearing decline in the high frequencies (OR 1.4, 95% CI 1.0; 1.8). Age, sex, household income, personal music player use, and body mass index were not associated with hearing decline. CONCLUSION: Educational level and risky behavior were significantly associated with hearing decline from childhood to early adolescence. The findings of the present study can help in the design of public health interventions to prevent hearing loss at a young age.

Distortion Product Otoacoustic Emissions in Screening for Early Stages of High-frequency Hearing Loss in Adolescents.

Objective: Adolescents may be at risk of noise-induced hearing loss due to recreational sound. The aim of this study was to examine the role of distortion product otoacoustic emissions (DPOAEs) in screening for early stages of high-frequency loss such as can be observed in noise-induced hearing loss. Setting and design: This cross-sectional study was embedded within Generation R, an ongoing prospective birth cohort study in Rotterdam, The Netherlands. Data were collected from April 2016 to September 2019. Methods: A total of 3456 adolescents with a mean age of 13 years and 8 months old (standard deviation ± 5 months) were included. Pure-tone thresholds were measured in a sound-treated booth. DPOAEs were recorded using an ILO V6 analyzer with primary levels of 65/55 dB SPL and frequency ratio f2/f1 of 1.22. Subjects had normal middle ear function at the time of assessment, based on tympanometry results. Results: Measurements in 6065 ears showed that DPOAE levels tend to decrease with increasing pure-tone thresholds. However, the intersubject variability of DPOAE levels in ears with the same threshold was large. DPOAE levels could reasonably identify early stages of high-frequency hearing loss. Conclusion: The findings of present study indicate that DPOAE measurements can potentially be used for adolescents hearing screening in the high frequencies. Future research is needed to optimize test performance.

Psychological Problems among Head and Neck Cancer Patients in Relation to Utilization of Healthcare and Informal Care and Costs in the First Two Years after Diagnosis.

BACKGROUND: To investigate associations between psychological problems and the use of healthcare and informal care and total costs among head and neck cancer (HNC) patients. METHOD: Data were used of the NETherlands QUality of Life and Biomedical Cohort study. Anxiety and depression disorder (diagnostic interview), distress, symptoms of anxiety and depression (HADS), and fear of cancer recurrence (FCR) and cancer worry scale (CWS) were measured at baseline and at 12-month follow-up. Care use and costs (questionnaire) were measured at baseline, 3-, 6-, 12-, and 24-month follow-up. Associations between psychological problems and care use/costs were investigated using logistic and multiple regression analyses. RESULTS: Data of 558 patients were used. Distress, symptoms of anxiety or depression, FCR, and/or anxiety disorder at baseline were significantly associated with higher use of primary care, supportive care, and/or informal care (odds ratios (ORs) between 1.55 and 4.76). Symptoms of anxiety, FCR, and/or depression disorder at 12-month follow-up were significantly associated with use of primary care, supportive care, and/or informal care (ORs between 1.74 and 6.42). Distress, symptoms of anxiety, and FCR at baseline were associated with higher total costs. DISCUSSION: HNC patients with psychological problems make more use of healthcare and informal care and have higher costs. This is not the result of worse clinical outcomes.

Health outcome priorities in older patients with head and neck cancer.

OBJECTIVES: Older patients with head and neck cancer often have comorbidity, have reduced life-expectancy and await intensive treatment. For the decision-making process, knowledge of a patient's health outcome prioritization is of paramount importance. We aim to study the health outcome priorities of older patients with head and neck cancer, and to evaluate whether general health, markers of physical, cognitive, and social functioning, and quality of life are associated with health outcome prioritization. MATERIALS AND METHODS: Patients aged ≥70 years with head and neck cancer received a Comprehensive Geriatric Assessment and their priorities were assessed using the Outcome Prioritization Tool (OPT). Distribution of first priority, and associations with general health, markers of physical, cognitive, and social functioning, and quality of life were evaluated using ANOVA or chi-square. RESULTS: Of the 201 included patients, the OPT was available in 170 patients. The majority prioritized maintaining independence (n = 91, 53.3%), followed by extending life (n = 58, 34.1%), reducing pain (n = 14, 8.2%), and reducing other symptoms (n = 7, 4.1%). Housing situation, Body Mass Index, presence of musculoskeletal diseases, and quality of life were significantly related to prioritization of health outcomes. Reducing pain or other symptoms was more often prioritized by patients who lived alone, had a history of musculoskeletal problems, or had poor perceived quality of life. Age, sex, comorbidity, and markers of physical and cognitive functioning were not associated with health prioritization. CONCLUSION: Maintaining independence is most often prioritized by older patients with head and neck cancer. In addition, we found that health outcome priorities of older patients are only limited based on general and specific health characteristics. We suggest to systematically discuss patients' priorities in order to facilitate complex treatment decisions in older patients with cancer.

Study retention and attrition in a longitudinal cohort study including patient-reported outcomes, fieldwork and biobank samples: results of the Netherlands quality of life and Biomedical cohort study (NET-QUBIC) among 739 head and neck cancer patients and 262 informal caregivers.

BACKGROUND: Longitudinal observational cohort studies in cancer patients are important to move research and clinical practice forward. Continued study participation (study retention) is of importance to maintain the statistical power of research and facilitate representativeness of study findings. This study aimed to investigate study retention and attrition (drop-out) and its associated sociodemographic and clinical factors among head and neck cancer (HNC) patients and informal caregivers included in the Netherlands Quality of Life and Biomedical Cohort Study (NET-QUBIC). METHODS: NET-QUBIC is a longitudinal cohort study among 739 HNC patients and 262 informal caregivers with collection of patient-reported outcome measures (PROMs), fieldwork data (interview, objective tests and medical examination) and biobank materials. Study retention and attrition was described from baseline (before treatment) up to 2-years follow-up (after treatment). Sociodemographic and clinical characteristics associated with retention in NET-QUBIC components at baseline (PROMs, fieldwork and biobank samples) and retention in general (participation in at least one component) were investigated using Chi-square, Fisher exact or independent t-tests (p< 0.05). RESULTS: Study retention at 2-years follow-up was 80% among patients alive (66% among all patients) and 70% among caregivers of patients who were alive and participating (52% among all caregivers). Attrition was most often caused by mortality, and logistic, physical, or psychological-related reasons. Tumor stage I/II, better physical performance and better (lower) comorbidity score were associated with participation in the PROMs component among patients. No factors associated with participation in the fieldwork component (patients), overall sample collection (patients and caregivers) or PROMs component (caregivers) were identified. A better performance and comorbidity score (among patients) and higher age (among caregivers) were associated with study retention at 2-years follow-up. CONCLUSIONS: Retention rates were high at two years follow-up (i.e. 80% among HNC patients alive and 70% among informal caregivers with an active patient). Nevertheless, some selection was shown in terms of tumor stage, physical performance, comorbidity and age, which might limit representativeness of NET-QUBIC data and samples. To facilitate representativeness of study findings future cohort studies might benefit from oversampling specific subgroups, such as patients with poor clinical outcomes or higher comorbidity and younger caregivers.

Assessing hearing loss in older adults with a single question and person characteristics; Comparison with pure tone audiometry in the Rotterdam Study.

INTRODUCTION: Hearing loss (HL) is a frequent problem among the elderly and has been studied in many cohort studies. However, pure tone audiometry-the gold standard-is rather time-consuming and costly for large population-based studies. We have investigated if self-reported hearing loss, using a multiple choice question, can be used to assess HL in absence of pure tone audiometry. METHODS: This study was performed within 4,906 participants of the Rotterdam Study. The question (in Dutch) that was investigated was: 'Do you have any difficulty with your hearing (without hearing aids)?'. The answer options were: 'never', 'sometimes', 'often' and 'daily'. Mild hearing loss or worse was defined as PTA0.5-4(Pure Tone Average 0.5, 1, 2 & 4 kHz) ≥20dBHL and moderate HL or worse as ≥35dBHL. A univariable linear regression model was fitted with the PTA0.5-4 and the answer to the question. Subsequently, sex, age and education were added in a multivariable linear regression model. The ability of the question to classify HL, accounting for sex, age and education, was explored through logistic regression models creating prediction estimates, which were plotted in ROC curves. RESULTS: The variance explained (R2) by the univariable regression was 0.37, which increased substantially after adding age (R2 = 0.60). The addition of sex and educational level, however, did not alter the R2 (0.61). The ability of the question to classify hearing loss, reflected in the area under the curve (AUC), was 0.70 (95% CI 0.68, 0.71) for mild hearing loss or worse and 0.86 (95% CI 0.85, 0.87) for moderate hearing loss or worse. The AUC increased substantially when sex, education and age were taken into account (AUC mild HL: 0.73 (95%CI 0.71, 0.75); moderate HL 0.90 (95%CI 0.89, 0.91)). CONCLUSION: Self-reported hearing loss using a single question has a good ability to detect hearing loss in older adults, especially when age is accounted for. A single question cannot substitute audiometry, but it can assess hearing loss on a population level with reasonable accuracy.

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.

Prevalence of Hearing Loss Among Children 9 to 11 Years Old: The Generation R Study.

Importance: Hearing loss (HL), a major cause of disability globally, negatively affects both personal and professional life. Objective: To describe the prevalence of sensorineural hearing loss (SNHL) among a population-based cohort of 9- to 11-year-old children, and to examine potential associations between purported risk factors and SNHL in early childhood. Design, Setting, and Participants: The study was among the general, nonclinical, pediatric community within the city of Rotterdam, the Netherlands, and was conducted between 2012 and 2015 as a cross-sectional assessment within the Generation R Study, a population-based longitudinal cohort study from fetal life until adulthood. Participants are children of included pregnant women in the Generation R Study with an expected delivery date between April 2002 and January 2006. They form a prenatally recruited birth cohort. Main Outcomes and Measures: Pure-tone air-conduction hearing thresholds were obtained at 0.5, 1, 2, 3, 4, 6, and 8 kHz, and tympanometry was performed in both ears. Demographic factors and parent-reported questionnaire data, including history of otitis media, were also measured. Results: A total of 5368 participants with a mean age of 9 years 9 months (interquartile range, 9 years 7 months-9 years 11 months) completed audiometry and were included in the analyses. A total of 2720 were girls (50.7%), and 3627 (67.6%) were white. Most of the participants (4426 children [82.5%]) showed normal hearing thresholds 15 dB HL or less in both ears. Within the cohort, 418 children (7.8%) were estimated to have SNHL (≥16 dB HL at low-frequency pure-tone average; average at 0.5, 1, and 2 kHz or high-frequency pure-tone average; average at 3, 4, and 6 kHz in combination with a type A tympanogram) in at least 1 ear, most often at higher frequencies. In multivariable analyses, a history of recurrent acute otitis media and lower maternal education were associated with the estimated SNHL at ages 9 to 11 years (odds ratio, 2.0 [95% CI. 1.5-2.8] and 1.4 [95% CI, 1.1-1.7], respectively). Conclusions and Relevance: Within this cohort study in the Netherlands, 7.8% of the children ages 9 to 11 years had low-frequency or high-frequency HL of at least 16 dB HL in 1 or both ears. A history of recurrent acute otitis media and lower maternal education seem to be independent risk factors for presumed SNHL in early childhood.

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.

Prevalence of age-related hearing loss, including sex differences, in older adults in a large cohort study.

OBJECTIVES/HYPOTHESIS: To obtain actual status of age-related hearing loss in a general unscreened population of older Dutch adults and to investigate whether the prevalence or degree has changed over time. STUDY DESIGN: To investigate the prevalence and degree of hearing loss, we conducted a large prospective cohort study of older adults between February 2011 and July 2015. METHODS: Pure-tone air- and bone-conduction thresholds were measured for 4,743 participants. Results were compared to previous cohort studies. RESULTS: As expected, hearing loss increased with age. We found a correlation of R2 = 0.317 for men and R2 = 0.354 for women (right ears). A prevalence of hearing loss greater than 35 dB hearing level the average of 0.5/1/2/4 kHz in the better ear, was found in 33% of the male and almost 29% of the female participants aged 65 years and older. Compared with previous studies, men had less hearing loss at the frequencies of 2 kHz and above. Hearing thresholds in women were significantly higher at 4 and 8 kHz. The difference in hearing loss between men and women is significantly less than in earlier studies. CONCLUSIONS: Our study confirms that hearing loss is highly prevalent in the general unscreened population of older adults. However, the difference in hearing between sexes was considerably less than previously reported. This is probably due to changing lifestyle and environmental circumstances, LEVEL OF EVIDENCE: 2b Laryngoscope, 127:725-730, 2017.

Using the Digits-In-Noise Test to Estimate Age-Related Hearing Loss.

OBJECTIVE: Age-related hearing loss is common in the elderly population. Timely detection and targeted counseling can lead to adequate treatment with hearing aids. The Digits-In-Noise (DIN) test was developed as a relatively simple test to assess hearing acuity. It is a potentially powerful test for the screening of large populations, including the elderly. However, until to date, no sensitivity or specificity rates for detecting hearing loss were reported in a general elderly population. The purpose of this study was to evaluate the ability of the DIN test to screen for mild and moderate hearing loss in the elderly. DESIGN: Data of pure-tone audiometry and the DIN test were collected from 3327 adults ages above 50 (mean: 65), as part of the Rotterdam Study, a large population-based cohort study. Sensitivity and specificity of the DIN test for detecting hearing loss were calculated by comparing speech reception threshold (SRT) with pure-tone average threshold at 0.5, 1, 2, and 4 kHz (PTA0.5,1,2,4). Receiver operating characteristics were calculated for detecting >20 and >35 dB HL average hearing loss at the best ear. RESULTS: Hearing loss varied greatly between subjects and, as expected, increased with age. High frequencies and men were more severely affected. A strong correlation (R = 0.80, p < 0.001) was found between SRTs and PTA0.5,1,2,4. Moreover, 65% of variance in SRT could be explained by pure-tone thresholds. For detecting mild or moderate hearing loss, receiver operating characteristics showed areas under the curve of 0.86 and 0.98, respectively. CONCLUSIONS: This study demonstrates that the DIN test has excellent test characteristics when screening for moderate hearing loss (or more) in an elderly population. It is less suited to screen for mild hearing loss. The test is easy to complete and should be suitable for implementation as an automated self-test in hearing screening programs. Ultimately, when combined with active counseling, hearing screening could lead to higher hearing aid coverage in the hearing impaired elderly.

Long-term functional airway assessment after open airway surgery for laryngotracheal stenosis.

OBJECTIVES/HYPOTHESIS: The purpose of this study was to evaluate our patient-reported and objective long-term outcomes of patients treated for laryngotracheal stenosis. STUDY DESIGN: Prospective cohort study. METHODS: Sixty-five patients were evaluated after a median follow-up of 7 years after surgery. Follow-up measurements consisted of pulmonary function testing, Bruce treadmill test, and Child Health Questionnaires (CHQ). RESULTS: Pulmonary function tests were available in 43 patients, and 30/43 had abnormal forced expiratory volume in 1 second/forced inspiratory volume in 1 second (FIV1), 25/43 had abnormal FIV1/maximum vital capacity, and 24/43 had abnormal peak expiratory flow. One-third of patients had reduced exercise tolerance. CHQ revealed significant positive correlations with pulmonary function results and exercise tolerance. Multivariate analysis showed that glottic involvement of the stenosis and the presence of comorbidities at time of surgery are the only factors for poor long-term functional outcome. CONCLUSIONS: The majority of patients show deficits in pulmonary function and exercise tolerance related to lower scores of quality of life. Glottic involvement of the stenosis and the presence of comorbidities are the only significant factors for poor functional outcome. Long-term multidisciplinary follow up is mandatory after surgery for laryngotracheal stenosis. LEVEL OF EVIDENCE: 2B.

Single Vocal Cord Irradiation: Image Guided Intensity Modulated Hypofractionated Radiation Therapy for T1a Glottic Cancer: Early Clinical Results.

PURPOSE: To report, from a retrospective analysis of prospectively collected data, on the feasibility, outcome, toxicity, and voice-handicap index (VHI) of patients with T1a glottic cancer treated by a novel intensity modulated radiation therapy technique developed at our institution to treat only the involved vocal cord: single vocal cord irradiation (SVCI). METHODS AND MATERIALS: Thirty patients with T1a glottic cancer were treated by means of SVCI. Dose prescription was set to 16 × 3.63 Gy (total dose 58.08 Gy). The clinical target volume was the entire vocal cord. Setup verification was done by means of an online correction protocol using cone beam computed tomography. Data for voice quality assessment were collected prospectively at baseline, end of treatment, and 4, 6, and 12 weeks and 6, 12, and 18 months after treatment using VHI questionnaires. RESULTS: After a median follow-up of 30 months (range, 7-50 months), the 2-year local control and overall survival rates were 100% and 90% because no single local recurrence was reported and 3 patients died because of comorbidity. All patients have completed the intended treatment schedule; no treatment interruptions and no grade 3 acute toxicity were reported. Grade 2 acute dermatitis or dysphagia was reported in only 5 patients (17%). No serious late toxicity was reported; only 1 patient developed temporary grade 2 laryngeal edema, and responded to a short-course of corticosteroid. The VHI improved significantly, from 33.5 at baseline to 9.5 and 10 at 6 weeks and 18 months, respectively (P<.001). The control group, treated to the whole larynx, had comparable local control rates (92.2% vs 100%, P=.24) but more acute toxicity (66% vs 17%, P<.0001) and higher VHI scores (23.8 and 16.7 at 6 weeks and 18 months, respectively, P<.0001). CONCLUSION: Single vocal cord irradiation is feasible and resulted in maximal local control rate at 2 years. The deterioration in VHI scores was slight and temporary and subsequently improved to normal levels. Long-term follow-up is needed to consolidate these promising results.

A prospective evaluation of patient-reported quality-of-life after (chemo)radiation for oropharyngeal cancer: which patients are at risk of significant quality-of-life deterioration?

BACKGROUND AND PURPOSE: To prospectively investigate the impact of different patients' characteristics on quality-of-life (QoL) after (chemo)radiation for oropharyngeal cancer (OPC). MATERIALS AND METHODS: Between 2008 and 2011, 207 patients were treated with 46-Gy of (chemo)-IMRT followed by a boost by means of IMRT, brachytherapy (BT), or Cyberknife (CK). QoL-assessment was performed using the EORTC QLQ-C30, and QLQ-H&N35-questionnaires at baseline, end of treatment, 2, 4, 6 weeks and 3, 6, 12, and 18 months after treatment. The correlation between patients' characteristics (AJCC-stage, tumor subsite, chemotherapy, neck dissection, unilateral neck irradiation, and boost technique), and changes in QoL over time were investigated. RESULTS: At 18months, improvements were seen in QLQ-C30 emotional functioning, insomnia, and pain and QLQ-H&N35 pain and speech. The scores on QLQ-H&N35 swallowing returned to baseline level while the scores on dry mouth, sticky saliva, opening mouth, and teeth were significantly deteriorated compared to baseline. Boost techniques and unilateral neck irradiation were significantly predictive for dry mouth, swallowing and opening mouth while chemotherapy was correlated with changes on swallowing and opening mouth scales. CONCLUSIONS: The most significant deterioration was seen in patient-related xerostomia. Boost technique, unilateral neck irradiation and chemotherapy were significantly predictive for QoL-changes over time.

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.

Multicolor fluorescence in situ hybridization analysis of a synovial sarcoma of the larynx with a t(X;18)(p11.2;q11.2) and trisomies 2 and 8.

Approximately 10% of all mesenchymal malignancies are classified as synovial sarcomas, which show a balanced translocation t(X;18)(p11.2;q11.2) at the cytogenetic level. The occurrence of this neoplasm in the head and neck region is rare, and its lowest frequency is found in the larynx. When synovial sarcomas are present in such unusual locations, diagnosis based solely on histologic features might be problematic, and to our knowledge, cytogenetic data have been reported so far in only one case of synovial sarcoma of the larynx. Because of the rarity and shortage of consistent prognostic markers, there is no clear consensus for the treatment of these patients. Cytogenetic analysis of a primary case of synovial sarcoma of the larynx was performed by using a 48-color fluorescence in situ hybridization technique that allows differential staining of short and long chromosome arms to establish the karyotype. We report here the molecular cytogenetic analyses of a synovial sarcoma of the larynx harboring the diagnostic t(X;18), as well as trisomies 2 and 8. The karyotypic information on synovial sarcomas of the larynx is scarce, and our data might add to the diagnosis and prognosis of this tumor.
