RESUMO
Head and neck cancer (HNC) patients suffer from a range of health-related quality of life (HRQoL) issues, but little is known about their long-term HRQoL. This study explored associations between treatment group and HRQoL at least 5 years' post-diagnosis in HNC survivors. In an international cross-sectional study, HNC survivors completed the European Organization for Research and Treatment of Cancer (EORTC) quality of life core questionnaire (EORTC-QLQ-C30) and its HNC module (EORTC-QLQ-H&N35). Meaningful HRQoL differences were examined between five treatment groups: (a) surgery, (b) radiotherapy, (c) chemo-radiotherapy, (d) radiotherapy ± chemotherapy and neck dissection and (e) any other surgery (meaning any tumour surgery that is not a neck dissection) and radiotherapy ± chemotherapy. Twenty-six sites in 11 countries enrolled 1105 survivors. They had a median time since diagnosis of 8 years, a mean age of 66 years and 71% were male. After adjusting for age, sex, tumour site and UICC stage, there was evidence for meaningful differences (10 points or more) in HRQoL between treatment groups in seven domains (Fatigue, Mouth Pain, Swallowing, Senses, Opening Mouth, Dry Mouth and Sticky Saliva). Survivors who had single-modality treatment had better or equal HRQoL in every domain compared to survivors with multimodal treatment, with the largest differences for Dry Mouth and Sticky Saliva. For Global Quality of Life, Physical and Social Functioning, Constipation, Dyspnoea and Financial Difficulties, at least some treatment groups had better outcomes compared to a general population. Our data suggest that multimodal treatment is associated with worse HRQoL in the long-term compared to single modality.

OBJECTIVES: to evaluate the disparities in access to cancer screening programmes in the Province of Pavia (Lombardy Region, Northern Italy), along with identifying the factors influencing these disparities; to assess the impact of the pandemic emergency on invitation and screening coverage in the three organized screening programmes, which are provided free of charge to the target population. DESIGN: observational retrospective study covering both the pre-pandemic and the pandemic periods. SETTING AND PARTICIPANTS: for breast cancer screening, the eligible population comprises women aged 45 to 74; colorectal cancer screening is offered to men and women aged 50 to 74; cervical cancer screening is tailored based on women age. The management of all three screening programmes is overseen by the Health Protection Agency of Pavia, which proactively invites the eligible population through invitation letters. MAIN OUTCOMES MEASURES: for each screening programme, the examination coverage (the number of screened individuals out of the total eligible population) was analysed considering its influencing factors, with a specific emphasis on equity-related factors such as demographics (sex, age), geographic factors (country and continent of birth, residential district), comorbidities. RESULTS: the SARS-CoV-2 pandemic has led to a reorganization of healthcare services and to a reduction of the offer, resulting in an overall reduction in test coverage for all three programmes (-16.3% for breast and colorectal cancer screening, -8.5% for cervical cancer screening). The disparities in coverage among various population groups, reflecting inequalities in access, further escalated from the pre-pandemic to the pandemic period. Noteworthy, equity-related predictors of reduced screening access were non-Italian nationality and residency in rural or mountainous districts. CONCLUSIONS: during periods of healthcare system strain, such as the pandemic, disparities in access can become more pronounced. It is crucial to implement measures for enhancing access to screening in a more equitable manner.

Melanoma of the external auditory canal (EAC) is particularly rare and poorly understood, with limited available data on management and survival. This systematic review aims to analyze existing data and provide insights into the management and prognosis the beginning of EAC melanoma. It is conducted using Pubmed and Scopus databases from the beginning to July 2023 and it follows the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. Searches are performed using the search string "(melanoma) AND (external auditory canal)".The review includes a total of 30 patients diagnosed with EAC melanoma, supplemented by an additional case from the authors' clinical experience. The role of Breslow thickness as a determining factor for the choice of surgery remains inconclusive due to limited available data. Sentinel lymph node biopsy and adjuvant therapy are sparingly employed, indicating the need for standardized guidelines. Patients in the study demonstrate a 50% overall survival rate at 5 years.EAC Melanoma is a rare and aggressive malignancy with limited therapeutic guidelines. Surgical interventions, including wide local excision and lateral temporal bone resection, are the primary treatment options for patients without distant metastases.

PURPOSE: Non-squamous cell carcinoma (non-SCC) accounts for about 5% of laryngeal malignancies. Survival data are limited, and consensus on management principles is lacking. The present study reviews our experience in the surgical treatment of non-metastatic non-SCC of the larynx and compares oncological and functional outcomes in a cohort of patients affected by traditional SCC. METHODS: We collected data on 592 patients affected by laryngeal neoplasms. Univariate and multivariable survival analyses were performed using Cox proportional-hazards models; survival estimates were reported by hazard ratios (HR) with 95% confidence intervals (CI), and survival curves were established with the Kaplan-Meier method. RESULTS: We identified 326 patients affected by untreated SCC, while 21 had non-SCC histotypes. The non-SCC cohort was composed of 5 soft tissue sarcomas, 8 chondrosarcomas, 2 adenoid cystic carcinomas, 2 neuroendocrine carcinomas, 2 solitary fibrous tumors, 1 Kaposi's sarcoma, and 1 malignant peripheral nerve sheath tumor. Overall survival and disease-specific survival were not significantly different according to histology (p = 0.6 and p = 0.349, respectively). The non-SCC group showed an increased risk of recurrence (HR 5.87; CI95 2.15-16.06; p < 0.001). Nonetheless, no significant difference (p = 0.31) was found at multivariable analysis between the two groups in total laryngectomy-free survival with an organ preservation rate over 5 years of 81% for the non-SCC histologies. CONCLUSION: Non-SCC is a broad spectrum pathology, but generalized laryngeal surgical management principles are still feasible and it is possible to identify patients amenable to conservative surgical treatment without affecting survival.

An unblinded retrospective analysis of prospectively collected data was carried out on 138 patients affected by glottic pT2 and selected pT3 squamous cell carcinomas (SCC) treated by transoral laser microsurgery (TLM). The entire cohort was divided into two groups: Group A included 78 "high-risk" patients (pT2 with impaired vocal cord mobility, pT3 for anterior paraglottic and/or pre-epiglottic space invasion, presence of angioembolization, perineural spread, and positive lymph nodes in the neck) who underwent postoperative surveillance by endoscopy and imaging (CT or MR), while Group B included 60 "low-risk" patients (pT2 with absence of the above-mentioned features) who underwent endoscopic follow-up alone. Aim of the present study was to assess the diagnostic gain in performing combined endoscopic and radiologic surveillance in the "high-risk" group compared to endoscopy alone in the "low-risk" one. There was no significant difference in terms of overall and disease-specific survivals between the two follow-up policies in spite of their different risk profiles. The same was true for organ preservation rate, which was 81% in the "high-risk" and 89% in the "low-risk" group. In contrast, the cumulative probability of disease-free survival was 54% for Group A and 65% for Group B (p = 0.0023). Therefore, our combined endoscopy and imaging surveillance protocol allowed increasing the submucosal recurrence detection rate in "high-risk" pT2-pT3 glottic SCC to 43%. An earlier detection of submucosal recurrences made salvage surgery by TLM feasible in at least half of cases, thus closing the gap between oncologic outcomes obtained in "high-"- vs. "low-risk" patients and leading to organ preservation rates that are favorably comparable to those obtained with open-neck partial laryngectomies and non-surgical organ preservation protocols.

OBJECTIVES: To evaluate outcomes in different malignancies involving the thyroid and infiltrating the airway submitted to tracheal (TRA) or crico-tracheal resection and anastomosis (CTRA). METHODS: Retrospective charts review of 27 patients affected by thyroid malignancies involving the airway treated by TRA/CTRA in a single academic institution. Kaplan-Meier curves were used to evaluate the overall (OS) and disease-specific (DSS) survivals and local (LC) and loco-regional control (LRC). Impact on survival of age, comorbidities, previous radiotherapy, types of TRA/CTRA, Shin's stage (II, III, IV), grading (well vs poorly differentiated), and length of airway resected was calculated by the log-rank test. RESULTS: Overall survival and DSS at 3 and 5 years were 82.3% and 71.6%, respectively. Local control and LRC in the entire group were 82.3% at 3 and 5 years. Crico-tracheal resection and anastomosis involving the cricoid arch and plate (type C) and tumor differentiation significantly affected OS and DSS (both P < .001). Type C CTRA and tumor differentiation significantly impacted on LC (P = .002 and P = .009, respectively). CONCLUSIONS: Grading and extension of CTRA to the cricoid plate are the most important factors for oncologic outcomes in thyroid malignancies infiltrating the airway. Except for poorly differentiated tumors, TRA/CTRA allows adequate LC even in advanced stage lesions involving the crico-tracheal junction.

The diagnostic value of narrow band imaging (NBI) in the "optical biopsy" of leukoplakias (LP) and erythroplakias (EP) in different oral cavity (OC) and oropharyngeal (OP) subsites is still to be defined. We evaluated 128 unbiopsied and untreated OC/OP LP and EP by conventional oral examination (COE), white light (WL) endoscopy, and NBI and categorized them as "suspicious" or "innocuous". All lesions were treated by excisional biopsy. True positives were those considered as "suspicious" and with histopathology ranging from mild dysplasia to invasive carcinoma. Epithelia were classified as follows: type 1, keratinized thick stratified (gingiva, hard palate, dorsal tongue); type 2a, non-keratinized thin stratified (floor of mouth, vestibule, ventral tongue, soft palate, palatine tonsils, base of tongue); type 2b, non-keratinized, very thick stratified (retromolar trigon, lateral tongue, labial and buccal mucosa). Histopathology revealed 32 % benign lesions, 13 % mild to moderate dysplasias, 15 % severe dysplasias/carcinoma in situ, 16 % microinvasive, and 23 % invasive carcinomas. The false positive rates were 32 % at COE, 27 % at WL, and 15 % at NBI. The false negative rates were 49, 22, and 11 %, respectively. Diagnositic performance was higher for NBI compared to COE (p < 0.001) and to WL (p = 0.004). Comparison of the diagnostic value of NBI among different OC/OP subsites did not show statistically significant difference. NBI as an "optical biopsy" tool significantly reduces the rates of false positives and false negatives in diagnosis of OC/OP cancer compared with COE and WL. No statistically significant difference was noted in its diagnostic value among different OC/OP subsites.

Multiple sclerosis (MS) is the main cause of chronic disability in young people during their most productive years of life and therefore carries a high social and economic burden. The present study aimed to: (1) verify the capacity of an administrative data source to furnish data for constructing a model able to detect the occurrence of clinical relapses in MS patients and (2) validate the constructed theoretical model on a set of real-world data. Two MS experts identified some administrative variables as proxies of clinical relapses. Thereafter, the two MS experts analysed 889 events in 100 MS patients, considering only the administrative data relating to these patients, while a third neurologist independently analysed the real-world data (documented medical history) of the same patients in the same period. Absolute concordance between the theoretical model and the real-world data was found in 86 % of the events. The model we propose is easily and rapidly applicable, requiring the collection of just a few variables that are already present in local health authority administrative databases in Italy. It can be used to estimate, with a good level of reliability, the occurrence of relapses in various settings. Moreover, the model is also exportable to different and larger MS cohorts and could be useful for healthcare planning and for evaluating the efficacy of drugs in the real-world, thus favouring better resource allocation and management.

This paper examines how commonly used earnings quality measures fulfill a key objective of financial reporting, i.e., improving decision usefulness for investors. We propose a stock-price-based measure for assessing the quality of earnings quality measures. We predict that firms with higher earnings quality will be less mispriced than other firms. Mispricing is measured by the difference of the mean absolute excess returns of portfolios formed on high and low values of a measure. We examine persistence, predictability, two measures of smoothness, abnormal accruals, accruals quality, earnings response coefficient and value relevance. For a large sample of US non-financial firms over the period 1988-2007, we show that all measures except for smoothness are negatively associated with absolute excess returns, suggesting that smoothness is generally a favorable attribute of earnings. Accruals measures generate the largest spread in absolute excess returns, followed by smoothness and market-based measures. These results lend support to the widespread use of accruals measures as overall measures of earnings quality in the literature.
RESUMO
BACKGROUND AND AIM: This study aims to assess the quality of the population-based breast cancer screening programme in Pavia, northern Italy computing its key performance indicators and estimating its sensitivity for the years 2016-2018. METHODS: Invitation and examination coverage, participation rate, recall rate, detection rate and positive predictive values were computed on the basis of data provided yearly to the Italian Ministry of Health. Sensitivity was estimated identifying interval cancers in the local Cancer Registry and computed with the proportional incidence method. RESULTS: In 2016-2018 the adjusted invitation coverage was 90%, and the adjusted participation rate was 62%. Recall rate was 8.4% for first screenings and 3.9% for subsequent ones. The number of screen-detected cases was 268, corresponding to a detection rate of 6.6 for first screenings and 4.6 for subsequent screenings. The number of interval cancers observed was 110 over the study period; the proportional incidence was 22% for the first interval year and 50% for the second interval. The overall sensitivity of the screening program was 64%. CONCLUSIONS: The analysis of performance indicators and sensitivity estimates for the Pavia programme indicates that the programme performance is in line with the quality standards set by the European Union and the Italian reference scientific society (GISMa).

Background: The current flows of the SSN represent the set of interest whose interconnection alone justifies the current study. These flows can be interconnected with other sources, institutional or otherwise, in order to answer well-defined questions. Objective: The objective of the study is to verify, through the analysis of administrative databases, any differences in the consumption of health resources between biological off-patent originator drugs and biosimilars in real clinical practice, with particular reference to the rheumatology area. Methods: Through the use of assisted databases (BDA) of ATS Pavia we evaluated the differences in terms of consumption of health resources related to the different drugs under analysis. Annual and daily costs were calculated by total patient cost, stratified for different treatments, considering the sum of total costs for the prescriptions of drugs subject to the analysis. Another objective was to evaluate the adherence of the drugs of interest, by utilizing specific indicators (MPR). Results: A total of 145 patients were analyzed. Among enrolled patients, 26.9% of users were treated with a biosimilar drug, while 73.1% with a biologic originator. Adherence is higher if it is considered the population treated with biosimilar drugs (82.1%). Total cost (including drug prescriptions, hospitalizations, outpatient services, tests for any cause) during the observation period of 1 year is 14,274.08. 87.7% of the total is attributable to drugs. Non-hospitalized patients are the least expensive, whether they were treated with biologics or biosimilars. Conclusion: In our sample, biosimilar drugs tend to be underused: the treatment of a patient with a chronic autoimmune disease is a clinical process that involves many health professionals, and a criticality could also derive from the difficult communication between the various professional figures who get involved with the whole patient treatment.
RESUMO
BACKGROUND AND AIM: Asthma and chronic obstructive pulmonary disease (COPD) are leading causes of morbidity and mortality worldwide. Globally, 545 million people suffer from chronic respiratory diseases with a wide geographical variability. Risk factors for asthma are both genetic and related to several environmental factors (internal and external pollutants); these also have an important role in the occurrence of COPD. The aim of this study was to describe the prevalence of asthma, COPD, and asthma/COPD overlap (ACO) in an adult population living in two municipalities located in the Po Valley. METHODS: A standardized questionnaire on respiratory symptoms and sociodemographic characteristics was self-administered to a random sample of the adult population aged 20-64 years, living near a refinery in Northern Italy during the period between 2016 and 2019. Logistic and multinomial regression were implemented to explore factors associated with asthma, COPD, and ACO. RESULTS: In total, 1108 subjects filled out the questionnaire, the mean age was 48.02 ± 12.34 years (range 21-68), and 53% of the respondents/participants were female. Half of the responders were non-smokers, but the frequency of current and former smokers was significantly greater in men than in women (p < 0.001). The likelihood of being a probable case of asthma decreased with increasing age and increased for smokers. Tobacco smoke was associated with the presence of COPD and ACO. CONCLUSION: Respiratory diseases such as asthma and COPD are common in the general population, with differences among countries worldwide. Our findings show, on the basis of the main confirmed risk factor, namely smoking, that it is useful to plan target programs and actions in order to reduce smoking, thus improving the quality of life in public health.
RESUMO
Excess mortality estimates are considered relevant indicators of direct and indirect pandemic effects on the population. Scant data have been published on cause-specific excess mortality. Using individual-level administrative data covering the Pavia province of Italian northern Lombardy region, we provided all-cause and cause-specific raw (RMR) and age-standardized (ASMR) mortality rates in 2021 and 2015-2019, the rate ratio, and 95% confidence intervals, overall and by sex. We obtained the excess deaths in 2021 as the difference between the number of observed and expected deaths from all causes and the two leading causes of death (all neoplasms and circulatory system diseases) by fitting over-dispersed quasi-Poisson regression models, accounting for temporal, seasonal and demographic changes. The total ASMR in 2021 was 972.4/100,000 (6836 certified deaths), with the highest ASMRs for circulatory system diseases (272.6/100,000) and all neoplasms (270.3/100,000), followed by COVID-19 (94.8/100,000 and 662 deaths). Compared to the expected, we estimated a total of 6.2% excess deaths in 2021 (7.2% in males and 5.4% in females), with no excess deaths from all neoplasms and a 6.2% reduction from circulatory system diseases. COVID-19 continued to affect total mortality in 2021, albeit to a lesser extent than in 2020, consistently with national patterns.

The long-term problems of head and neck cancer survivors (HNCS) are not well known. In a cross-sectional international study aimed at exploring the long-term quality of life in this population, 1114 HNCS were asked to state their two most serious long-term effects. A clinician recorded the responses during face-to-face appointments. A list of 15 example problems was provided, but a free text field was also available. A total of 1033 survivors responded to the question. The most frequent problems were 'dry mouth' (DM) (n = 476; 46%), 'difficulty swallowing/eating' (DSE) (n = 408; 40%), 'hoarseness/difficulty speaking' (HDS) (n = 169; 16%), and 'pain in the head and neck' (PHN) (n = 142; 14%). A total of 5% reported no problems. Logistic regression adjusted for age, gender, treatment, and tumor stage and site showed increased odds of reporting DM and DSE for chemo-radiotherapy (CRT) alone compared to surgery alone (odds ratio (OR): 4.7, 95% confidence interval (CI): 2.5-9.0; OR: 2.1, CI: 1.1-3.9), but decreased odds for HDS and PHN (OR: 0.3, CI: 0.1-0.6; OR: 0.2, CI: 0.1-0.5). Survivors with UICC stage IV at diagnosis compared to stage I had increased odds of reporting HDS (OR: 1.9, CI: 1.2-3.0). Laryngeal cancer survivors had reduced odds compared to oropharynx cancer survivors of reporting DM (OR: 0.4, CI: 0.3-0.6) but increased odds of HDS (OR: 7.2, CI: 4.3-12.3). This study provides evidence of the serious long-term problems among HNCS.
RESUMO
The COVID-19 pandemic had an unfavorable impact on overall mortality in Italy, with the strongest consequences in northern Italy. Scant data are available on cause-specific mortality. This study aims at investigating the impact of the pandemic on the overall and cause-specific mortality in one province in northern Italy, Pavia. We linked individual-level administrative data (i.e., death certification and population data) from the Health Protection Agency (HPA) in Pavia province between 2015 and 2020. We computed age-standardized mortality rates (Italian population 2011) by cause, sex, and calendar year, and computed the rate ratio and the corresponding 95% confidence intervals to compare rates in 2020 versus 2015-2019. The 2020 excess total mortality in Pavia was 24% in men and 25% in women, reaching rates of 1272.6/100,000 and 1304.4/100,000, respectively. Significant excesses were found for infectious and parasitic diseases, excluding COVID-19 (about +30% in both sexes); respiratory system diseases (44% in men; 30% in women); and dementia and Alzheimer's disease among men (24%). Reductions were reported for neoplasms (-14% in men); cerebrovascular diseases (-25% in men); and ischemic diseases (-13% in women), but also for transport accidents in men. COVID-19 was the third cause of death in both sexes with rates of 274.9/100,000 men (859 total deaths) and 213.9/100,000 women (758 total deaths). Excess mortality in Pavia was higher than Italy but lower than Lombardy. Increases in mortality from causes related to infectious and respiratory diseases can likely be explained by underdiagnosed deaths from COVID-19.

Lockdown and social distancing, as well as testing and contact tracing, are the main measures assumed by the governments to control and limit the spread of COVID-19 infection. In reason of that, special attention was recently paid by the scientific community to the mathematical modeling of infection spreading by including in classical models the effects of the distribution of contacts between individuals. Among other approaches, the coupling of the classical SIR model with a statistical study of the distribution of social contacts among the population, led some of the present authors to build a Social SIR model, able to accurately follow the effect of the decrease in contacts resulting from the lockdown measures adopted in various European countries in the first phase of the epidemic. The Social SIR has been recently tested and improved through a fruitful collaboration with the Health Protection Agency (ATS) of the province of Pavia (Italy), that made it possible to have at disposal all the relevant data relative to the spreading of COVID-19 infection in the province (half a million of people), starting from February 2020. The statistical analysis of the data was relevant to fit at best the parameters of the mathematical model, and to make short-term predictions of the spreading evolution in order to optimize the response of the local health system.

BACKGROUND: A landmark for the identification of the lingual artery (LA) through a transoral perspective can provide surgeons with an easy method to prevent and manage intraoperative bleeding during transoral approach to the base of tongue (BOT). METHODS: Thirteen tongue and five head and neck specimens were dissected to identify and assess the reliability of the lingual point (LP) as a new landmark for the LA at BOT. The pathway of 42 LAs was radiologically evaluated; axial depth and vertical offset were measured for each LA. RESULTS: Dissection study: a description of LP is provided; the LA was easily identified in all specimens (36/36 sides) using LP as a landmark. Radiologic study: the mean depth of the LA was 4.2 mm, the mean vertical offset was 1.3 mm. CONCLUSIONS: LP is a simple and reliable landmark for identification of the LA, potentially helping surgeons to prevent and manage intraoperative bleeding.

BACKGROUND: The alcohol-related problems (ARPs) are a relevant issue in public health and contribute to premature deaths and avoidable disease burden. The capture-recapture (C-R) method can be a useful tool to provide reliable estimates for populations with hidden nature such as subjects with ARP. METHODS: C-R method was used to estimate the 'true count' of individuals with ARP using three independent health-related current databases in an area of northern Italy during 2007. To predict the frequency of unascertained cases, we constructed log linear models. The goodness-of-fit of a model was measured by the likelihood ratio test and the final model was selected using Akaike's Information Criterion. Confidence intervals (CIs) were calculated according to Hook and Regal. RESULTS: Altogether 1014 subjects with ARP were directly identified from the three sources using the C-R method the estimated unknown population was 2729 subjects, giving a total of 3743 subjects with ARP (95% CI 3148-4504) and a prevalence of 8.24 (95% CI 7.97-8.50) per 1000 inhabitants aged >15 years. The analyses stratified for gender estimated 12.31/1000 (95% CI 11.85-12.77) men and 4.86/1000 (95% CI 4.58-5.14) women with ARP. Besides, the analysis calculated a prevalence of 14.99 per 1000 (95% CI 14.29-15.69) for males <50 years (1731), corresponding to the majority of subjects with ARP. CONCLUSION: The C-R technique is useful to provide a more realistic picture of the size of ARP population. This has important implications both for future planning of service provision and for the way in which the impact of ARP interventions are evaluated.

INTRODUCTION: Carbon dioxide laser coagulation during transoral laser microsurgery (TLM) for laryngeal cancer allows control of bleeding from vessels smaller than 0.5 mm. Therefore, larger arteries and veins must be carefully managed by clipping and/or monopolar cautery. The aim of this paper is to detail endolaryngeal vascular anatomy and identify areas of possible bleeding during TLM. METHODS: We performed an anatomical study on a series of 11 fresh-frozen human cadavers. After injection of a bicomponent red silicone into the innominate, left common carotid, and left subclavian arteries, 22 hemilarynges were dissected, the course of the supraglottic, glottic, and subglottic vessels were traced after microdissection of the intervening structures, and their size measured at specific landmark points where such vessels are more frequently encountered during TLM. RESULTS: Three vessels arising from the superior laryngeal artery were identified after its entry point at the level of the thyro-hyoid membrane: (1) the epiglottic artery (EA), documented in 100% of cases, a common trunk dividing into two main vessels (2) the postero-inferior artery (PIA), present in 100% of the specimens, running downward and dividing in a posterior (pPIA), and anterior (aPIA) branches (3) the antero-inferior artery (AIA), present in 95% of our specimens, running downward to the anterior commissure (AC). Two transverse anastomotic networks (TANs) connected the AIA and PIA, both parallel to the vocal muscle, one lateral (present in 100% of cases), and another medial (91% of specimens). Finally, a fourth vessel supplying the glottic plane was found to be the endolaryngeal paracommissural branch of the crico-thyroid artery (PCA), arising from the inferior laryngeal artery and emerging just below the AC, through the crico-thyroid membrane (reported in 100% of the specimens). This vessel anastomosed in 91% of cases with the AIA, through one or both of the TANs. CONCLUSION: The course of the endolaryngeal arteries, their relationships with adjacent structures, and size at specific landmark points have been herein described in order to provide surgeons with a map to guide them during the steep learning curve of transoral surgery of the larynx, with special emphasis given to TLM.
RESUMO
OBJECTIVES/HYPOTHESIS: There is no general consensus on what kind of examination to include in an optimal detection strategy for head and neck squamous cell carcinomas of unknown primary (SCCUPs). This study investigates the role of narrow-band imaging (NBI) in their identification. STUDY DESIGN: Case series. METHODS: Twenty-nine consecutive patients affected by SCCUPs were referred at two academic institutions. Selection criteria were: 1) lymph node cytology positive for squamous cell carcinoma (SCC); 2) no evidence of any primary at white light (WL); 3) negative contrast-enhanced computed tomography (CT) and/or magnetic resonance imaging, and positron emission tomography-CT; and 4) no contraindication to general anesthesia. Each patient underwent office-based NBI panendoscopy. If a suspicious area was identified, a biopsy was performed for histological confirmation. When no suspicious area was detected in the office, patients underwent WL and NBI under general anesthesia. If this examination was still negative, bilateral tonsillectomy and base of the tongue (BOT) mucosectomy were performed. RESULTS: Office-based NBI identified 10 SCCs (34.5%), one in the nasopharynx, three in the tonsil, four in the BOT, and two in the supraglottis. In only one (3.5%) NBI-negative patient was a primary found in the BOT. In one (3.5%) we found an NBI suspicious area during panendoscopy under general anesthesia, but histology did not confirm this finding after BOT mucosectomy. Seventeen (58.6%) patients remained as having true SCCUPs. NBI sensitivity, specificity, positive, negative predictive values, and accuracy were 91%, 95%, 91%, 95%, and 90%, respectively. CONCLUSIONS: In the present study, office-based NBI increased the detection rate of head and neck SCCUPs by 34.5% and should be strongly recommended as an adjunctive tool in their diagnostic workup.
