RESUMO

PURPOSE: Historically managed with intranasal corticosteroids (INCS) and endoscopic sinus surgery (ESS), type-2 Chronic RhinoSinusitis with Nasal Polyps (CRSwNP) treatment was revolutionized by the introduction of dupilumab but universally accepted guidelines are still lacking. METHODS: Patients treated at our University Hospital for type-2 CRSwNP were enrolled. Demographic data were collected, as well as laboratory (eosinophils, total IgE), endoscopic [nasal polyps score (NPS), modified Lund-Kennedy score (mLKS)], radiological [Lund-Mackay score (LMS) at CT scan], SNOT-22, and olfactory [Sniffin' Sticks identification test (SSIT)] features. Patients were treated with dupilumab or ESS and re-evaluated after 3 and 12 months. RESULTS: At 3 and 12 months, patients undergoing ESS achieved a higher reduction of NPS and mLKS, while patients receiving dupilumab experienced a higher improvement at SNOT-22 and SSIT with a greater positive variation in the prevalence of anosmia (- 57.7% vs - 42.9%) and normosmia (+ 37.8 vs + 28.5%). Mean mLKS and LMS were quite similar. Results were independent of clinical features known to contribute to CRSwNP severity, except for patients with ≥ 2 prior ESS who had a significantly lower smell improvement. CONCLUSION: ESS and dupilumab were effective at reducing CRSwNP inflammatory burning. CRSwNP smell impairment cannot be attributed only to olfactory cleft obstruction and other mechanisms may be involved. Dupilumab acts systemically with poor correlation with NPS. As of today, dupilumab appears to be more suitable for elderly patients with anesthesiological contraindications and/or several previous surgeries, while ESS may represent the first-line choice in surgery-naive patients.

RESUMO

INTRODUCTION: The recent approval of Dupilumab has profoundly revolutionized the management of patients affected by severe and recalcitrant Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). However, a review that summarizes the results of real-life studies and compares them to phase 3 studies SINUS-24 and 52 is still lacking. MATERIALS AND METHODS: A search of all real-life studies published from 2019 to 2023 was performed. Patients characteristics at baseline and 6 and 12 months after starting Dupilumab were extracted and compared to those from phase 3 trials: age, sex, smoking habits, comorbid asthma and aspirin-exacerbated respiratory disease (AERD), previous endoscopic sinus surgery (ESS), hematic eosinophils and total IgE, NasalAQ2 Polyps Score (NPS), smell, SNOT-22, adverse events (AEs), and response to treatment. RESULTS: 15 papers were included with an overall number of 1658 patients. A higher rate of comorbidities and previous ESS was found in patients from real-life studies. In addition, they had worse smell and SNOT-22 at baseline compared to patients from SINUS-24 and 52. Comorbid and post-ESS patients tended to have a faster NPS and SNOT-22 improvement, although the absolute values were not clinically relevant. A more extensive surgery and a number of ESS ≥ 2 were related to worse olfactory outcomes, probably due to iatrogenic damage. No correlation was found between hematic eosinophils and outcomes. AEs were reported by 12.4% of patients and 2.2% had to discontinue dupilumab. Weight gain was an emergent AE (0.8%), probably related to the restored sense of smell and taste. Non-responders were 3.5% and they were switched to systemic steroid, ESS, or another biologic. CONCLUSION: Despite some differences in prescription criteria between countries, dupilumab was demonstrated to be effective even in the real-life scenario. However, emerging AEs and possible unknown long-term AEs of a likely lifelong therapy should be considered.

RESUMO

BACKGROUND: In mice models, eosinophils have been divided into different subpopulations with distinct phenotypes and functions, based on CD62L and CD101 patterns of membrane expression. Limited data are available in humans. OBJECTIVE: To investigate eosinophils subpopulations in peripheral blood (PB) and nasal polyp tissue (NP) from severe eosinophilic asthma (SEA) patients plus concomitant chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS: We recruited 23 SEA patients (14 with CRSwNP); as controls, we enrolled 15 non-severe asthma patients, 15 allergic rhinitis patients without asthma and 15 healthy donors. Eosinophils were isolated from PB and NP and analysed by FACS. Eotaxin-3 and eotaxin-1 mRNA expression in NP tissue was also evaluated. RESULTS: A significantly higher percentage of circulating CD62Llow cells was observed in SEA, as compared with controls, expressing higher levels of CCR3, CD69 and lower levels of CD125 (IL-5R), CRTH2, CD86 and CD28 in comparison with CD62Lbright cells. In NP, eosinophils showed a high proportion of CD62Llow phenotype, significantly greater than that observed in PB. Surface expression of IL-3R, IL-5R, CD69 and CD86 was significantly higher in CD62Llow eosinophils from NP than in those from blood. Moreover, eotaxin-3 mRNA expression positively correlated with the percentage of CD62Llow cells in NP. CONCLUSION: Two different eosinophil subphenotypes can be identified in blood and NP of SEA patients, with a preferential accumulation of CD62Llow inflammatory cells in NP.

RESUMO

BACKGROUND: Eosinophils have been divided into different subpopulations with distinct phenotypes based on CD62L expression. No data are available regarding the correlation between eosinophils subphenotypes and clinical severity of asthma, as well as the effect of anti-IL-5 therapy on these cells. The study investigates the correlation between blood CD62Llow inflammatory eosinophils (iEos) and clinical severity of severe eosinophilic asthma (SEA) and evaluates the impact of mepolizumab on iEos. METHODS: 112 patients were screened and were divided in two groups: biological-naive (n = 51) and biological-treated patients (n = 61). The Biological-naive patients were analyzed before treatment (Group A) and 19 out of 51 patients, were longitudinally analyzed before and after treatment with mepolizumab 100 mg s.c/4 weeks (Group B); 32 patients were excluded because they were being treated with other biological therapies. Blood eosinophils were analyzed by FACS and correlated with clinical scores. In vitro effect of IL-5 and mepolizumab on CD62L expression was assessed. RESULTS: A significant correlation between blood CD62Llow cells and clinical scores of asthma and nasal polyps, as well as the number of asthma exacerbations in the last year was shown in untreated patients. In longitudinally studied patients we observed a marked reduction of CD62Llow cells paralleled by an increase in the proportion of CD62Lbright cells, associated with clinical improvement of asthma control. In vitro, CD62L expression on eosinophils is modulated by IL-5 and anti-IL-5. CONCLUSION: A positive correlation between CD62Llow iEos and the baseline clinical features of SEA with CRSwNP was shown. Furthermore mepolizumab restores the healthy balance among eosinophils sub-phenotypes in SEA patients.

RESUMO

BACKGROUND: The oncological and functional role of postoperative radiotherapy (PORT) after open partial laryngeal surgery (OPLS) remains debatable. METHODS: A systematic review and a meta-analysis of the literature were conducted according to the PRISMA guidelines. Outcomes of patients receiving OPLS with and without PORT for laryngeal cancer were summarized. RESULTS: In the 10 studies that were included in the meta-analysis, no significant difference emerged in terms of pooled overall survival between OPLS patients who did and who did not receive PORT (- 0.3%, 95% CI - 5.4 to 4.9%, p = 0.922). Only one study showed a significantly higher incidence of complications in the PORT cohort. CONCLUSIONS: PORT may apparently be performed after OPLS in face of adverse postoperative features without an increased risk of toxicities affecting the neolarynx. Because of the limitations in the available literature, the oncological and functional effects of PORT in this setting needs to be prospectively assessed to strengthen the evidence of this treatment strategy for laryngeal cancer.

RESUMO

PURPOSE: Otoendoscopy represents the initial non-invasive diagnostic cornerstone for external and middle ear disorders. Recently, new techniques of enhanced imaging such as narrow-band imaging (NBI) have been introduced but their role as a potential aid in otological practice remains unproven. In this pictorial review, we want to present the potential application of this endoscopic method, highlight its limitations, and give some hints regarding its future implementation. METHODS: Representative cases of external and/or middle ear pathologies were selected to illustrate the role of NBI in this regard. RESULTS: NBI may represent a useful aid in the otological work-up, in the differential diagnosis of ear tumor-like masses, and, possibly, in the prognosis of tympanic perforations. For other ear disorders, instead, this technique does not seem to add anything to the standard clinical practice. CONCLUSIONS: NBI might prove useful in the assessment of selected external and middle ear disorders but its role must be prospectively validated.

RESUMO

Cigarette smoking is the main risk factor for head and neck cancer (HNC) and many HNC patients are active smokers at diagnosis. We conducted a systematic literature review and meta-analysis to quantify the survival impact of smoking cessation at or around the time of HNC diagnosis. We searched studies published until December 31, 2021, and used random-effects meta-analysis to pool study-specific estimates into summary hazard ratio (SHR) and corresponding 95% confidence intervals (CI). Sixteen studies were published between 1983 and 2021, and over 2300 HNC patients were included. Studies were diverse in terms of design, patients, tumours and treatment characteristics, and criteria used to discriminate quitters from continued smokers. HNC patients who quit smoking at or around diagnosis had significantly better overall survival than continued smokers (SHR 0.80, 95% CI 0.70-0.91, n studies = 10). A beneficial effect of post-diagnosis smoking cessation was suggested for other survival endpoints as well, but the results were based on fewer studies (n = 5) and affected by publication bias. Cessation counselling should be offered to all smokers who start a diagnostic workup for HNC and should be considered standard multidisciplinary oncological care for HNC patients. PROSPERO registration number CRD42021245560.

RESUMO

BACKGROUND: The identification of early diagnostic and prognostic biomarkers in oral squamous cell carcinoma (OSCC) is an unmet clinical need. We hypothesized that extracellular vesicles miR-210 expression (EV-miR-210) could be a potential biomarker for OSCC diagnosis and follow-up. METHODS: The expression of EV-miR-210 was measured in the plasma of OSCC patients (n = 30) and compared to that of controls (n = 14). RESULTS: The median EV-miR-210 expression was significantly higher in OSCC patients compared to controls who had often, undetectable levels (p < 0.0001). We performed receiver operating characteristic (ROC) analysis for discriminating OSCC cases from controls. EV-miR-210 yielded an area under the curve (AUC) of 0.9513 with sensitivity 92.3% and specificity 86.6%. Kaplan-Meier curves indicated that high EV-miR-210 expression was associated with worse 3 years' survival (p < 0.05). Cox regression hazard model indicated that high EV-miR-210, G2, and G3 grading and pathological nodal status (pN)>1 were independent predictors of worse survival in OSCC patients. CONCLUSION: These preliminary data suggest that EV-mir-210 may be a novel diagnostic and prognostic biomarker in OSCC.

RESUMO

The sphenoid bone is an unpaired bone that contributes to the formation of the skull base. Despite the enormous progress in transnasal endoscopic visualisation, imaging techniques remain the cornerstones to characterise any pathological condition arising in this area. In the present review, we offer a bird's-eye view of the developmental, inflammatory, and neoplastic alterations affecting the sphenoid body and clivus, with the aim to propose a practical diagnostic aid for radiologists based on clinico-epidemiological, computed tomography, and magnetic resonance imaging features.

RESUMO

PURPOSE: Advanced-stage laryngeal cancer is a challenging disease that needs multimodal treatment. Medical and surgical organ-preservation strategies have been developing in the last decades to spare these functions while granting cancer cure. The current work presents the experience of a tertiary-care center in conservative surgery for advanced-stage laryngeal cancer. MATERIALS AND METHODS: We collected clinical data of patients submitted to open partial horizontal laryngectomies (OPHLs) and any possible adjuvant treatment from 2005 to 2018. Outcomes were also compared to the most recent studies reporting on both medical and surgical organ-preservation strategies. RESULTS: One hundred ten patients were included in the analysis. Adjuvant therapy was employed in 51% of cases. The local control rate was 96.4%, while overall survival (OS) was 67%, and laryngo-esophageal dysfunction free survival (LEDFS) was 66%. Stage IV and vascular invasion were associated with a statistically-significant worse survival. CONCLUSIONS: OPHLs are valid as upfront treatment in fit patients affected by advanced-stage laryngeal cancer. Disease control and function preservation are granted in a significant percentage of cases, even when followed by adjuvant therapy.

RESUMO

Tissue-resident memory (Trm) cells are specialized components of both CD4+ and CD8+ T cell subsets that persist in peripheral nonlymphoid tissues following infections and provide fast response in case of a secondary invasion by the same pathogen. Trm cells express the surface markers CD69, CD103, and the immune checkpoint molecule PD-1. Trm cells develop not only in the context of infections but also in tumors, where they can provide a line of defense as suggested by the positive correlation between the frequency of tumor-infiltrating Trm cells and patients' survival. Trm cells persistence in peripheral tissues depends on their adaptation to the local microenvironment and the presence of survival factors, mainly IL-7, IL-15, and Notch ligands. However, the cell sources of these factors are largely unknown, especially in the context of tumors. Here, we show that head-neck squamous cell carcinoma (HNSCC) is enriched in CD4+ and CD8+ T cells with a Trm phenotype. Moreover, we show that mesenchymal stromal cells that accumulate in HNSCC are a source of survival factors and allow proper expression of Trm-typical markers in a VCAM1-dependent manner.

RESUMO

OBJECTIVES: Olfactory and gustatory dysfunction (OD/GD) are now recognized as typical symptoms of COVID-19 infection. However, their pathogenesis remains unclear and no clear prognostic factors have been identified. We have analyzed a cohort of mild/moderate hospitalized patients to identify possible clinical or immunological predictors of recovery from OD/GD. METHODS: Clinical and biological parameters were reviewed along with associated comorbidities. Chemosensory Complaint Score was administered on admission and 30 days after the first negative swab. Unpaired Wilcoxon and chi-squared tests were used to compare the variables in the patients who recovered versus those who did not. RESULTS: From a cohort of 119 hospitalized patients, 43 (36%) reported OD/GD on admission. 60.6% had a full recovery from OD and 69.2% from GD. Only the concentration of IL-10 on admission emerged as significantly associated with recovery of taste (p = 0.041) while allergic respiratory disease was more prevalent in the group who did not recover from OD (p = 0.049) and GD (p = 0.007). CONCLUSION: These findings suggest that COVID-19 associated OD/GD is an inflammatory-mediated condition and that clinical and immunological parameters could predict the evolution of these symptoms.

RESUMO

Control of the novel COronaVIrus Disease-2019 (COVID-19) in a hospital setting is a priority. A COVID-19-infected surgeon performed surgical activities before being tested. An exposure risk classification was applied to the identified exposed subjects and high- and medium-risk contacts underwent active symptom monitoring for 14 days at home. All healthcare professionals (HCPs) were tested for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) at the end of the quarantine and serological tests were performed. Three household contacts and 20 HCPs were identified as high- or medium-risk contacts and underwent a 14-day quarantine. Fourteen HCPs and 19 patients were instead classified as low risk. All the contacts remained asymptomatic and all HCPs tested negative for SARS-CoV-2. About 25-28 days after their last exposure, HCPs underwent serological testing and two of them had positive IgM but negative confirmatory swabs. In a low COVID-19 burden area, the in-hospital transmission of SARS-CoV-2 from an infectious doctor did not occur and, despite multiple and frequent contacts, a hospital outbreak was avoided. This may be linked to the adoption of specific recommendations and to the use of standard personal protective equipment by HCPs.

RESUMO

BACKGROUND: Head and neck cancer (HNC) survivors are particularly vulnerable to the deleterious consequences of lockdown and social distancing. The psychosocial effects of the COVID-19 pandemic on this group are still unknown, and we want to explore how their quality of life (QoL) has changed in this unique situation. MATERIALS AND METHODS: An online survey, composed of pandemic-specific items, plus the EORTC QLQ-C30, was administered to a cohort of HNC survivors. Using previously published reference values as a control group, we have evaluated the impact of the pandemic on their QoL. We have also explored the differences between those who had received a total laryngectomy (LP, laryngectomized population) vs other HNC patients, in order to assess the role of tracheostomy in this regard. RESULTS: One hundred and twenty-one HNC patients completed the survey. The scores of the physical (80.5 vs 85, p = 0.028), role (78 vs 84, p = 0.030), and emotional functioning (76 vs 81, p = 0.041) were significantly different in the two groups, with worse functioning in our patients. Comparing LP with the other HNC patients, social (76.6 vs 88.9, p = 0.008) and physical functioning (75.5 vs 86.1, p = 0.006) were significantly worse in the former group. LP also reported a greater perception that others are afraid to be close to them (1.67 vs 1.32, p = 0.020). No differences were found between LP with and without voice prosthesis. CONCLUSIONS: Our results show how HNC patients are at high risk for a worsening in QoL because of the ongoing COVID-19 global pandemic.

RESUMO

PURPOSE: Cancer patients are regarded as a group at risk for both COVID-19 infection and severe clinical course because of advanced age, comorbidities and iatrogenic immune impairment. Among them, patients with cancer of the upper and lower airways share other risk factors, mostly related to tobacco-smoke exposure, including male gender, airway epithelial damages, chronic obstructive respiratory disease (COPD), cardiovascular and cerebrovascular diseases. Clinical and pathophysiological factors shared by these conditions are reviewed. METHODS: Review of the published literature since the beginning of 2020. RESULTS: COVID-19 is a respiratory infectious disease and SARS-CoV-2 replication and shedding occurs in nasal and bronchial epithelial respiratory cells through the interaction with ACE2 and TMPRSS2 receptors, both overexpressed in smokers and former smokers. Tobacco-smoke airway exposure is also characterized by a chronic inflammation with activation of inflammatory cells and cytokine release including interleukin-6 (IL-6). A high release of cytokine in response to viral infection is documented in COVID-19 patients with adverse clinical outcomes and IL-6 is a key element of the cytokine storm syndrome leading to multi-organ damage. CONCLUSIONS: Patients with cancers of the upper and lower airways might be at increased risk of infection, morbidity and mortality from COVID-19 also because of tobacco exposure, a key factor in triggering inflammation, immunity and cancer.

RESUMO

ABSTRACT: The diagnosis and management of cerebrospinal fluid (CSF) rhinorrhea remains an important challenge in the field of rhinology. In this study, the authors want to propose a technique for transnasal endoscopic closure of CSF fistulas, tested for the first time on 2 adult fresh cadaveric specimens. The authors think that the use of a device similar to the umbrella device, used to close cardiac atrial defects, may also be valid for the closure of defects at the level of the anterior skull base.

RESUMO

INTRODUCTION: There is urgent need to find a swift and cheap way to safely perform routine endoscopic procedures during the otolaryngological and anesthesiological practice. We want to share our experience of a novel device, inspired by the pediatric head box experience. MATERIALS AND METHODS: Five otolaryngologists and four anesthesiologists were asked to visualize the glottic plane by using the device. A total of 15 attempts was allowed to reach the vocal folds within 60 seconds after entering the box. Student's t-test for unpaired samples was used to compare groups. RESULTS: Transnasal laryngoscopy through our endobox could be successfully performed by all the physicians involved and the mean number of attempts before visualizing and passing the glottis for the first time was 2.8 (range 1-5) in the otolaryngologists' group versus 3.2 (range 1-6) in the anesthesiologists' group (P=0.583). Out of the 15 attempts, the group of otolaryngologists reached the glottis 10.2 times, on average, against 9.7 in the other group (P=0.692). CONCLUSIONS: Our endobox seems a practical and feasible strategy to control droplets diffusion during standard ear, nose, and throat and anesthesiological practice.

RESUMO

OBJECTIVES: To evaluate thyroid, arytenoid, and cricoid cartilage invasion on computed tomography (CT) imaging in patients undergoing total laryngectomy for both primary and recurrent laryngeal carcinoma. Secondary endpoint was to compare laryngeal cartilage invasion between primary and recurrent tumours. METHODS: Pre-treatment CT of 40 patients who had undergone total laryngectomy was retrospectively evaluated and compared with histology. Focal erosions of thyroid cartilage were accounted for neoplastic invasion of the inner cortex. Full-thickness thyroid cartilage invasion was defined as a tumour-like tissue replacing thyroid cartilage or extended in extra-laryngeal soft tissues. Sclerosis and erosion of arytenoid and cricoid cartilages were assessed as signs of neoplastic invasion. RESULTS: CT erosion showed perfect agreement for thyroid inner cortex and cricoid cartilage invasion and almost perfect agreement (87%) for arytenoid cartilage invasion. For tumours in contact with thyroid cartilages, the absence of CT erosion underestimated inner cortex infiltration. CT showed perfect agreement in predicting full-thickness thyroid cartilage invasion only in the case of extra-laryngeal neoplastic extension. Arytenoid sclerosis showed poor correlation with neoplastic invasion. For primary tumours, CT demonstrated good (inner cortex 75%; full-thickness 85%), substantial (67.5%), and perfect (100%) accuracy in thyroid, arytenoid, and cricoid cartilage invasion, respectively. No CT differences were observed between primary and recurrent laryngeal tumours. CONCLUSION: Tumour-like tissue extension in the extra-laryngeal soft tissues was accurate in predicting thyroid cartilage full-thickness invasion. Erosions of arytenoid, cricoid, and thyroid cartilages' inner cortex on CT were highly indicative of neoplastic infiltration. No CT difference in cartilage infiltration between primary and recurrent tumours was observed.

RESUMO

BACKGROUND AND OBJECTIVES: Postoperative morbidity after open partial laryngeal surgery (OPLS) may be serious, leading to a prolonged length of hospital stay and increasing costs. We sought to define the predictive factors of complications and to develop nomograms for patients eligible for OPLS based on clinical and surgical data. METHODS: We critically reviewed 535 patients with laryngeal carcinoma who underwent OPLS at our Institution from 1982 to 2007. We have identified patients affected by postoperative local, airway, dysphagia, bleeding, surgical site infection, dehiscence of pexy, emphysema, and laryngocutaneous fistula complications. We have analyzed them according to age, smoking, alcohol, tumor site, clinical T and N classification, type of OPLS and neck dissection, previous treatments. Prognostic factors were considered in a multivariate logistic regression model with backward stepwise elimination and selected to construct and design nomograms for overall and specific complications. The performance was assessed using the c-index, receiver operating characteristic, and calibration curves. RESULTS: Age, clinical T classification, type of OPLS, and alcohol were related to overall (35%) and airway complications. Nomograms were built for overall, dysphagia, and airway complications. CONCLUSIONS: We have developed nomograms that can identify high-risk patients undergoing OPLS and that can help to prevent severe complications and to tailor surgical planning.

RESUMO

PURPOSE: Investigate the incidence, the degree and the effect of gastro-pharyngeal reflux (GPR) in laryngectomised patients. MATERIALS AND METHODS: Behavioral and 24-hour pH- and impedance-monitoring data were prospectively analyzed for 25 laryngectomised patients with no previous history of GER in outpateints' setting. Reflux detected was characterized as either acid, weakly acidic or nonacid. Proximal reflux was found at 15cm above the LES. RESULTS: 40% of patients presented a pathological number of reflux episodes in the upright position (p<0.0001); 9 of them presented a pathologic bolus exposure time. Bolus exposure at the proximal sphincter was one fourth-fold lower than 5cm above the LES (p=0.3593). There was a prevalence of acid reflux at both sphincters (p<0.0001); liquid reflux was prevalent at the LES (p=0.003) and mixed reflux at the UES (p=0.0001). Median REs was higher than time acid exposure (p=0.0013). CONCLUSIONS: Pre- and post-surgical reflux investigation could identify preexisting reflux severity and screen potential high-risk cancer patients for postoperative complications. This might allow the early onset of acid suppressive therapy in presence of pathologic findings in high-complication risk cancer patients.
