RESUMO

ChatGPT is an advanced language model developed by OpenAI, designed for natural language understanding and generation. It employs deep learning technology to comprehend and generate human-like text, making it versatile for various applications. The aim of this study is to assess the alignment between the Rhinology Board's indications and ChatGPT's recommendations for treating patients with chronic rhinosinusitis with nasal polyps (CRSwNP) using biologic therapy. An observational cohort study involving 72 patients was conducted to evaluate various parameters of type 2 inflammation and assess the concordance in therapy choices between ChatGPT and the Rhinology Board. The observed results highlight the potential of Chat-GPT in guiding optimal biological therapy selection, with a concordance percentage = 68% and a Kappa coefficient = 0.69 (CI95% [0.50; 0.75]). In particular, the concordance was, respectively, 79.6% for dupilumab, 20% for mepolizumab, and 0% for omalizumab. This research represents a significant advancement in managing CRSwNP, addressing a condition lacking robust biomarkers. It provides valuable insights into the potential of AI, specifically ChatGPT, to assist otolaryngologists in determining the optimal biological therapy for personalized patient care. Our results demonstrate the need to implement the use of this tool to effectively aid clinicians.

RESUMO

Background: this prospective study investigated the correlation between the oral bacterial microflora and the microflora found in voice prostheses (VPs) among 20 patients who had undergone laryngectomy. The aim was to explore the associations between the microflora's presence and the malfunction of VPs, along with the association between the predominant microorganism and the longevity of VPs. Methods: the research process included gathering medical histories, conducting ENT examinations, replacing VPs, and performing check-ups every four months for a period of 15.5 months. Additionally, microbiological examinations, blood tests, and voice change surveys were conducted. Results: a correlation between the microflora isolated from VPs and that from oral rinses was demonstrated in a large percentage of patients who experienced a loss of prosthetic functional efficiency. The correlation analysis between the type of microorganism and the lifespan of VPs showed a non-significant Pearson correlation coefficient (r = 0.043, p = 0.678). Conclusions: there is no significant linear correlation between the predominant microorganism and the average lifespan of VPs.

RESUMO

OBJECTIVE: This study aimed to evaluate the effectiveness and safety of dupilumab during the first year of treatment in a real-life setting, focusing on improvement in nasal polyp score (NPS) as well as specific symptoms, quality of life and olfactory function. METHODOLOGY/PRINCIPAL: A multicentric observational cohort study was carried out. A total of 170 patients were enrolled in the Otorhinolaryngology Unit of the three University Hospitals and considered for dupilumab therapy. All recorder characteristics were age (at the first dupilumab application visit), sex, smoke habits, previous local and systemic corticosteroid therapy, history of endoscopic sinus surgery, number of previous endoscopic sinus surgery, concomitant asthma, history of an allergic condition, immunoglobulin E (IgE), allergy to nonsteroidal anti-inflammatory drugs (NSAIDs), Aspirin Exacerbated Respiratory Disease (AERD), other comorbidities associated, blood eosinophils, nasal polyp score, sinonasal outcome test 22 (SNOT 22), sniffin' stick test, the start date of dupilumab therapy and number of doses of dupilumab and eventually, Dupilumab's adverse events related to administration. The Wilcoxon test for dependent samples was performed to compare variables. Statistical significance was assumed for p values < 0.05. RESULTS: A statistically significant reduction in SNOT-22 and NPS was shown at the 6th and 12th month compared to baseline values (p < 0.001 for both comparisons). A statistically significant increase value at the Sniffin' sticks test was shown in the 6th and 12th month compared to baseline values (p < 0.001 for both comparisons). At the 12-month follow-up, according to EUFOREA indications, all patients were considered to remain in treatment with dupilumab and continued the treatment because of a reduced NPS, improved quality of life and a reduced need for system corticosteroids. Dupilumab seemed to be well tolerated by all patients. Any adverse effect of the drug led to the quit of biological treatment. CONCLUSIONS: This multi-centric real-life study supported the effectiveness of dupilumab as an add-on therapy to intranasal corticosteroids in patients with severe uncontrolled CRSwNP in improvement of quality of life, severity of symptoms, polyp size reduction and smell function. Furthermore, our data support the safety profile of monoclonal therapy with dupilumab.

RESUMO

Objective: To establish the safety and effectiveness of subtotal petrosectomy with cochlear implantation in patients affected by chronic middle ear disorders to refractory to previous surgical treatments. Methods: A multicentre, retrospective study was conducted on patients affected by recalcitrant chronic middle ear disorders who underwent cochlear implantation in combination with subtotal petrosectomy. Patients' details were collected from databases of 11 Italian tertiary referral centres. Additionally, a review of the most updated literature was carried out. Results: 55 patients were included with a mean follow-up time of 44 months. Cholesteatoma was the most common middle ear recurrent pathology and 50.9% of patients had an open cavity. 80% of patients underwent a single stage surgery. One case of explantation for device failure was reported among the 7 patients with post-operative complications. Conclusions: Subtotal petrosectomy with cochlear implantation is a benchmark for management of patients with recalcitrant chronic middle ear disorders. A single stage procedure is the most recommended strategy. Optimal follow-up is still debated. Further studies are required to investigate the role of this surgery in paediatric patients.

RESUMO

To date, histological biomarkers expressed by laryngeal cancer are poorly known. The identification of biomarkers associated with laryngeal squamous cell carcinoma (SCC), would help explain the tumorogenesis and prevent the possible recurrence of the lesion after treatment. For this reason, the aim of this study is to investigate, for the first time, the Orphanin expression in 48 human specimens of laryngeal SCC and evaluate its possible correlation with patients prognosis. We analyzed pathological specimens from 48 patients with laryngeal SCC to detect the presence of Orphanin by using an immunohistochemistry test. We compared the findings with healthy tissue acquired from patients who underwent surgery for mesenchymal benign tumours of the larynx. The specimens were stained with anti-Orphanin monoclonal antibodies. Results were processed through a computerised image analysis system to determine a scale of staining intensity. All the tumoural specimens examined showed a significant immunoreaction for Orphanin when compared with healthy tissues (p < 0.05) but with a different immune reactivity related to clinical-pathological features. A high Orphanin expression was not significantly related to Histological Grading (HG), TNM, and stage (p > 0.05). In the multivariate analysis, the Orphanin expression was significantly related only to the malignant recurrence (p < 0.05). Our study suggests that Orphanin could have a role in tumorigenesis by increasing the recurrence of cancer; therefore, it should be further explored as a possible biomarker for laryngeal cancer.

RESUMO

PURPOSE: Few evidence-based therapies are available for chronic olfactory dysfunction after COVID-19. This study investigated the relative efficacy of olfactory training alone, co-ultramicronized palmitoylethanolamide with luteolin (um-PEA-LUT, an anti-neuroinflammatory supplement) alone, or combined therapy for treating chronic olfactory dysfunction from COVID-19. METHODS: This double-blinded controlled, placebo-controlled multicenter randomized clinical trial was conducted in 202 patients with persistent COVID-19 olfactory dysfunction of > 6 month duration. After a screening nasal endoscopy, patients were randomized to: (1) olfactory training and placebo; (2) once daily um-PEA-LUT alone; (3) twice daily um-PEA-LUT alone; or (4) combination of once daily um-PEA-LUT with olfactory training. Olfactory testing (Sniffin' Sticks odor identification test) was performed at baseline and at 1, 2, and 3 months. The primary outcome was recovery of over three points on olfactory testing, with outcomes compared at T0, T1, T2 and T3 across groups. Statistical analyses included one-way ANOVA for numeric data and chi-square for nominal data. RESULTS: All patients completed the study, and there were no adverse events. At 90 days, odor identification scores improved by > 3 points in 89.2% of patients receiving combined therapy vs. 36.8% receiving olfactory training with placebo, 40% receiving twice daily um-PEA-LUT alone, and 41.6% receiving once daily um-PEA-LUT alone (p < 0.00001). Patients receiving treatment with um-PEA-LUT alone demonstrated subclinical improvement (< 3 point odor identification improvement) more often than patients receiving olfactory training with placebo (p < 0.0001.) CONCLUSIONS: Olfactory training plus once daily um-PEA-LUT resulted in greater olfactory recovery than either therapy alone in patients with long-term olfactory function due to COVID-19. TRIAL REGISTRATION: 20112020PGFN on clinicaltrials.gov. LEVEL OF EVIDENCE: 1b (Individual Randomized Clinical Trial).

RESUMO

PURPOSE: Retraction pocket (RP) is a common event affecting the middle ear when a negative pressure within it causes a retraction of a single part of the tympanic membrane (TM). Patients can be asymptomatic or can experience hearing loss, fullness feeling and/or ear discharge. RP can be stable or develop a cholesteatoma; aim of the study was to investigate if mastoidectomy may play a role in the surgical management of patients suffering from RP, both reporting our experience and discussing the existing literature. METHODS: Fifty-one patients affected by RP were referred for surgery and randomly divided into two groups. Patients of G1 group underwent tympanoplasty with mastoidectomy, patients of G2 group underwent tympanoplasty only. A systematic review of the literature was then carried out by applying the PRISMA guidelines. RESULTS: The mean follow-up lasted about 36 months. The G1 and G2 groups reached a postoperative mean air-bone gap (ABG) of 7.1 dB HL and 5.1 dB HL, respectively, with a mean ABG improvement of 13.2 dB HL and 12.4 dB HL. An ABG improvement was observed in the 59.7% of the G1 group and in the 63.2% of the G2 group, respectively (p > 0.5). Only one case of long-term complication was recognized in the G1 group. We combined, integrated and analyzed results of our prospective study with results of the literature review. CONCLUSIONS: Based on the combined results of our study and literature review we may conclude that there is no evident benefit in performing mastoidectomy for the treatment of RP. In fact, no differences in ABG improvement or in RP recurrence were reported between the two groups.

RESUMO

Human papillomavirus is a sexually transmitted virus that is responsible not only for uterine cervical cancer, but also for the oral and oropharyngeal cancers. In this latter case, the virus indiscriminately affects both sexes at any age. Vaccination plays a key role in preventing infection and its possible consequences. Therefore, this study aimed to assess the degree of awareness of papillomavirus infection and its possible prevention in the Sicilian population. A prospective observational study was carried out on the Sicilian population through a self-administered questionnaire, consisting of 10 multiple-choice questions. The survey lasted from June 2021 to December 2021. A total of 844 respondents were included: 60.90% were female and 53.55% were aged between 21 and 30 years. Most of the surveyed population knew about the virus and the existence of the vaccine, however, many of them did not know about virus's effects on the oral and oropharyngeal sites (49.17%), or about the indication for vaccination for males (39.69%). Oral and oropharyngeal papillomavirus-related cancers are an increasingly frequent finding, especially in young adults. Therefore, it is necessary and quite mandatory to educate the population about the risks that certain voluptuous habits may cause, with the help of general practitioners, schools, social media, and social networks.

RESUMO

Narrow-band imaging (NBI) represents a valid aid in laryngeal squamous cell carcinoma (LSCC) diagnosis for detecting vascular changes. However, LSCC and laryngeal papillomatosis (LP) show similar vascular patterns that may lead to misdiagnosis and improper treatment. This review aims to deepen this NBI limit in order to stress a careful preoperative evaluation of laryngeal lesions. The research was carried out on PubMed, Web of Science and Scopus databases using specific keywords. The topic of research was assessed by these parameters: accuracy, sensitivity, specificity, and positive and negative predictive values. This review included only five articles: they demonstrated that NBI is better than white-light endoscopy in detecting LSCC and LP. They also reported that LP is frequently mistaken for LSCC, resulting in high rates of false positives using NBI. This is the first review that emphasized this NBI limitation in distinguishing between LP and LSCC in cases of a type V pattern of intraepithelial papillary capillary loop. Although NBI application increased the rate of early cancer detection, LP reduces NBI accuracy. This drawback may lead to misdiagnosis and improper treatment. Our advice is to be careful in cases of type V pattern on NBI and to research LP epithelial and clinical features because it could be a pitfall.

RESUMO

Objective: This study reports our experience in a selected cohort of patients affected by mild-moderate OSAS, without tonsillar obstruction, and treated with pharyngoplasty. Methods: In a case-control retrospective study, we compared modified expansion sphincter pharyngoplasty (MESP) to modified barbed reposition pharyngoplasty (MBRP) in adult patients with oropharyngeal transversal collapse with a BMI ≤ 30 kg/m2, and mild-moderate obstructive sleep apnoea syndrome (OSAS). A clinical evaluation, including collection of anthropometric data and sleep endoscopy, was performed. Six months after surgery, symptoms recording, clinical evaluation and polysomnography (PSG) were repeated. Results: We enrolled 20 patients: 10 treated with MESP and 10 treated with MBRP. Mean apnoea-hypoapnoea index (AHI) was 22.8 (± 5.63). We observed in both groups a significant reduction of AHI and oropharyngeal obstruction (p = 0.01), with a success rate, according with Sher's criteria, of 90% for MESP and 80% for MBRP, respectively. Post-surgical pain and snoring reduction were significantly lower with MBRP. Conclusions: We recorded similar success rates for both techniques. MBRP may be considered better than MESP due to less surgical time, no potential mucosal damage, absence of knots, and faster recovery with less pain.

RESUMO

Background: Effective swallowing represents the main challenge in supraglottic laryngectomy. This study aimed to assess swallowing outcome comparing endoscopic supraglottic laryngectomy (ESL) and open partial horizontal laryngectomy type I (OPHL I). Methods: A retrospective study was carried out on 20 patients that underwent supraglottic laryngectomy from 2015 to 2021: 10 underwent ESL (group A) and 10 underwent OPHL I (Group B). Patients underwent fiberoptic endoscopic evaluation of swallowing (FEES) 3 months and 12 months after surgery and videofluoroscopy swallowing studies (VFSS) 12 months after surgery. A Swallowing Outcome After Laryngectomy (SOAL) questionnaire was administered to patients to assess their life quality. Results: A naso-gastric tube was placed in two patients of Group A and in all patients of Group B. Tracheostomy was performed in two patients of Group A and in all patients in Group B and it has been closed in 100% of them. According to Donzelli's scale, FEES and VFSS showed better results in Group A at 3 months, while at 12 months they did not show statistically significant differences between ESL and OPHL I in terms of laryngeal penetration and aspiration. The SOAL questionnaire showed satisfactory life quality. Conclusion: Swallowing evaluation by FEES and VFSS did not demonstrate statistically significant differences at 12 months post-op between two surgeries, although ESL showed less cases of laryngeal penetration and aspiration at 3 months post-op. Anyway, good results of any surgery depend on careful patient selection and the surgeon's experience.

RESUMO

Introduction: One of the most important complications of OSAHS in children is growth delay. The aim of this study was to investigate changes in clinical body growth, and laboratory growth in children with OSAHS after adeno-tonsillar surgery. Materials and Methods: In our study, among 102 children suffering from sleep-disordered breathing, 70 met the inclusion criteria because they were affected by OSAHS and adenotonsillar hypertrophy. In total, 96 children affected by adeno-tonsillar hypertrophy (55 males and 41 females) underwent nocturnal cardiorespiratory monitoring with Embletta MPR, monitoring for post-operative 24 hours. Patients underwent blood sampling to evaluate preoperative GH and IGF-1 serum levels, "placement" in Cacciari's growth charts and adenotonsillectomy and saturation monitoring for post-operative 24 hours. According to auxological parameters, 82.86% of the patients were below the fiftieth percentile of BMI Cacciari's growth charts and IGF-1 preoperative serum levels were below the normal range. All patients underwent adenotonsillectomy. Results: All 70 patients recovered from OSAHS according to the results of nocturnal cardiorespiratory monitoring after six months. IGF-1 serum levels significantly increased after three months and one year after. All the auxological parameters showed a significant increase after surgery. We calculated the average annual growth in height of the patients before and after adenotonsillectomy (AT): the growth rate was impaired by OSAHS (5.4±1.3 cm/year), while in the following year post-surgery we found a significant growth speed acceleration (9.9±1.7 cm/year, P=0.001). Conclusions: In conclusion, growth delay in children can be caused by OSAHS, and when it is due to adenotonsillar hypertrophy, adenotonsillectomy is to be considered as the therapy of choice.

RESUMO

BACKGROUND: The relationship between nasal functions and middle ear surgery is still under debate. Nasal obstruction is considered as a negative prognostic factor in middle ear surgery. This is based on the theory that it may cause Eustachian tube dysfunction (ETD) by leading to reduced ventilation of the middle ear, as found in several patients with nasal septal deviation, chronic rhinitis and nasal polyps. OBJECTIVES: To assess how the subjective feeling of nasal function, evaluated by a preoperative questionnaire, may be predictive of surgical outcome and/or risk of failure in middle ear surgery. METHODS: We prospectively evaluated data of patients undergoing middle ear surgery for chronic otitis media with and without cholesteatoma. All patients completed the SNOT-22 and ETDQ-7 questionnaires. They underwent surgery for their pathology, as appropriate. RESULTS: The SNOT-22 score was higher in patients with retraction pocket and in patients whose retraction pockets recurred after surgery (p < 0.05). Patients with higher score at SNOT-22 questionnaire, were more likely to show recurrence of atelectasis aftersurgery. CONCLUSIONS: The SNOT-22 questionnaire, administrered before surgical procedure, can help in the identification of patients who are at risk of failure in the post-operative period, as well as ETDQ-7.

RESUMO

OBJECTIVE: Tumours of the nasal septum are a rare and heterogeneous group of lesions in the sinonasal tract. The management of the different lesions of this site is debated. The aim of this study is to share our experience on a rare clinical condition and stimulate other centres to publish theirs. METHODS: We retrospectively analysed the databases of sinonasal tumours treated at the Sections of Otolaryngology (ENT) of two University Hospitals (Palermo and Genova) between 2012 and 2020. RESULTS: From the two databases, a cohort of 32 patients with tumours of nasal septum were selected. All patients underwent an endoscopic examination. Large tumours underwent preoperative computed tomography (CT) scan without contrast medium. In 22 (68.7%) cases, the preoperative radiologic evaluation also included magnetic resonance imaging (MRI) with gadolinium to obtain a better differentiation of the lesions and study the vascular pattern. All the large lesions were biopsied under endoscopic guidance using local anaesthesia; the same approach was used to remove the tumours and their attachment with safe resection margins. CONCLUSIONS: While malignant lesions require an excision of the mass with resection of all layers of the nasal septum, benign lesions must be typed according to histological considerations in order to plan the most appropriate type of surgical resection.

RESUMO

PURPOSES: Reporting our experience in treating chronic obstructive sialadenitis with a protocol consisting of sialoendoscopy and intraductal instillation of antibiotics, steroids and n-acetyl-cysteine (NAC) solution. METHODS: Prospective study of patients with chronic obstructive sialadenitis with no apparent lithiasic obstructions, with recurrent non-lithiasic sialoadenitis and patients with lithiasic sialoadenitis not solved with sialoendoscopy. In all cases, a sialoendoscopy was performed. All the patients affected by lithiasic sialoadenitis where the chronic inflammation was resolved with sialoendoscopy were excluded from the study. The mid-term follow-up was performed at 12 months via phone interview, to understand whether patients had developed any further symptoms after the treatment. RESULTS: This study included 26 patients. All the patient without sialolithiasis have not reported any symptoms during the follow-up period. Two of those with sialolithiasis have not shown any signs of recurrence. The remaining three patients with non-resolved sialolithiasis had a recurrence of symptoms which were treated again with 1 intraductal administration of betamethasone, gentamicine and NAC, showing immediately a regression of the symptoms. CONCLUSIONS: Intraductal administration of gentamicin + NAC + betamethasone seemed effective for the therapy of chronic obstructive sialoadenitis. Our protocol seemed effective also in that cases where it was not possible to remove or detect endoscopically an obstruction. In all these cases we have noticed an increase in the symptom-free time even in cases where it was not possible to remove the stones.

RESUMO

INTRODUCTION: There are many fibrin-derived sealants used as topical haemostatic agents in many surgical procedures. Fibrin sealants are usually non-autologous derivatives or animal derivatives, with the exception of Vivostat®, an autologous fibrin sealant derived from patients own blood. MATERIALS AND METHODS: We present our experience on the use of Vivostat® in skull base closures in 20 patients operated at the Otorhinolaryngology Unit of the Hospital Ospedali Riuniti Villa Sofia - Cervello of Palermo. All postoperative patients were placed in an anti-trendeleburg position for 48 hours. After removal of the nasal swabs we did not find any rhinorrhea and we checked the tightness of the skull base defect with computed tomography. RESULTS: On a total of the 20 patients (10 post-traumatic and 10 with iatrogenic leaks), 9 out of 10 post-traumatic cases had a leak in the border area between the anterior and posterior portion of the ethmoid, while 1 patient out of 10 post-traumatic cases had a leak at the level of the sella. In all 20 patients, we repaired skull base defects by fixing grafting materials with Vivostat®. We have not had any complications. Vivostat® is a useful product in skull base repair and safe for the patients. CONCLUSION: Vivostat® has been used as a sealant on body tissues with greater elasticity and more resistant allowing better and safer wound repair, especially in skull base surgery. In particular, its immediate polymerisation is very useful for an evaluation of the mechanical sealants in the closure of the skull base cerebrospinal fluid leak.

RESUMO

(1) Background: Inferior turbinates' hypertrophy is often associated with Eustachian tube dysfunction (ETD); radiofrequency turbinate reduction (RTR) may provide a long-term improvement of nasal obstruction and ETD-related symptoms. (2) Aim: The study aimed to compare ETD in atopic and non-atopic patients before and after RTR and to investigate the correlation between tympanometry and Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7). (3) Methods: Ninety-seven patients, ranging from 33 to 68 years old, were screened by skin tests and divided into atopic (G1) and non-atopic (G2). Eustachian tube function (ETF) was evaluated through tympanometry, William's test and ETDQ-7. (4) Results: A moderate to severe subjective ETDQ-7 was found in the 35.42% of G1 and in the 22.45% of G2 patients before RTR. William's test resulted normal in 141 ears (72.68%), partially impaired in 15 (7.73%), and grossly impaired in 38 (19.59%) before surgery. A grossly ETD was evidenced in the 19.59% of cases before surgery and decreased to 6.18% after surgery with a significant difference among atopic patients (p < 0.001). (5) Conclusion: RTR may be considered a treatment option in patients suffering from ETD and inferior turbinates' hypertrophy; RTR reduced the percentage of grossly impaired ET function (p < 0.001). ETDQ-7 and William's test may represent valuable tools to assess ET function before and after surgery.

RESUMO

Obstructive sleep apnoea syndrome is a chronic condition characterized by frequent episodes of collapse of upper airways during sleep. Prevalence of the disease is settled at about 3-7%. Today, palatal surgery is a reference point in OSAHS treatment and there are many different surgical techniques. The purpose of our work is to compare post-operative results of palate surgery techniques used in our practice in OSAHS patients, studying the degree of patients' satisfaction with a recent score recommended by Rashwan et al. called PPOPS (Palate Post-Operative Problems Score). A retrospective study was performed on a sample of 40 patients subject to different palate surgery techniques for OSAS. Analysed surgical techniques were: Expansion Sphincter Pharyngoplasty (ESP), Uvulopalatopharyngoplasty (UPPP), Anterior Pharyngoplasty (AP), Barbed Reposition Pharyngoplasty (BRP). Patients answered the PPOPS and the results for each of the four techniques were compared. Group differences in the questionnaire total score were evaluated through Tukey's honest significance test for multiple (pairwise) comparisons. Overall average scores in the four groups were: AP 2.21, ESP 5.92, UPPP 2.8 and BRP 2.4. Comparing ESP with the other techniques (BRP, AP and UPPP) the scores were significantly higher (P < 0.05). Pairwise comparisons between the other three techniques (FA, UPPP and BRP) had a P value higher than 0.05, allowing to state that questionnaire results, in these cases, were similar to each other. Our work shows that different surgical techniques, even with the same purpose, could have different characteristics during follow-up. PPOPS is useful in post-operative for a better surgical practice.

RESUMO

Abstract Introduction: The treatment of laryngeal squamous cell carcinoma needs accurate risk stratification, in order to choose the most suitable therapy. The prognostic significance of resection margin is still highly debated, considering the contradictory results obtained in several studies regarding the survival rate of patients with a positive resection margin. Objective: To evaluate the prognostic role of resection margin in terms of survival and risk of recurrence of primary tumour through survival analysis. Methods: Between 2007 and 2014, 139 patients affected by laryngeal squamous cell carcinoma underwent partial or total laryngectomy and were followed for mean of 59.44 ± 28.65 months. Resection margin status and other variables such as sex, age, tumour grading, pT, pN, surgical technique adopted, and post-operative radio- and/or chemotherapy were investigated as prognostic factors. Results: 45.32% of patients underwent total laryngectomy, while the remaining subjects in the cohort underwent partial laryngectomy. Resection margins in 73.39% of samples were free of disease, while in 21 patients (15.1%) anatomo-pathological evaluation found one of the margins to be close; in 16 subjects (11.51%) an involved resection margin was found. Only 6 patients (4.31%) had a recurrence, which occurred in 83.33% of these patients within the first year of follow-up. Disease specific survival was 99.24% after 1 year, 92.4% after 3 years, and 85.91% at 5 years. The multivariate analysis of all covariates showed an increased mortality rate only with regard to pN (HR = 5.043; p = 0.015) and recurrence (HR = 11.586; p = 0.012). Resection margin did not result an independent predictor (HR = 0.757; p = 0.653). Conclusions: Our study did not recognize resection margin as an independent prognostic factor; most previously published papers lack unanimous, methodological choices, and the cohorts of patients analyzed are not easy to compare. To reach a unanimous agreement regarding the prognostic value of resection margins, it would be necessary to carry out meta-analyses on studies sharing definition of resection margin, methodology and post-operative therapeutic choices.


Resumo Introdução: O tratamento do carcinoma de células escamosas de laringe necessita de uma estratificação precisa do risco, para a escolha da terapia mais adequada. O significado prognóstico da margem de ressecção ainda é motivo de debate, considerando-se os resultados contraditórios obtidos em vários estudos sobre a taxa de sobrevida de pacientes com margem de ressecção positiva. Objetivo: Avaliar o papel prognóstico da margem de ressecção em termos de sobrevida e risco de recorrência de tumor primário através da análise de sobrevida. Método: Entre 2007 e 2014, 139 pacientes com carcinoma de células escamosas de laringe foram submetidos à laringectomia parcial ou total e foram acompanhados por um tempo médio de 59,44 ± 28,65 meses. O status de margem de ressecção e outras variáveis, como sexo, idade, grau do tumor, pT, pN, técnica cirúrgica adotada e radio- e/ou quimioterapia pós-operatória, foram investigados como fatores prognósticos. Resultados: Dos pacientes, 45,32% foram submetidos à laringectomia total, enquanto os demais foram submetidos à laringectomia parcial. As margens de ressecção em 73,39% das amostras estavam livres, enquanto em 21 pacientes (15,1%) a avaliação anatomopatológica encontrou uma das margens próxima e 16 indivíduos (11,51%) apresentaram margem de ressecção comprometida. Apenas seis pacientes (4,31%) apresentaram recidiva, o que ocorreu em 83,33% desses pacientes no primeiro ano de seguimento. A sobrevida doença-específica foi de 99,24% em um ano, 92,4% em três anos e 85,91% em cinco anos. A análise multivariada de todas as covariáveis mostrou um aumento na taxa de mortalidade apenas em relação à pN (HR = 5,043; p = 0,015) e recidiva (HR = 11,586; p = 0,012). A margem de ressecção não demonstrou ser um preditor independente (HR = 0,757; p = 0,653). Conclusões: Nosso estudo não identificou a margem de ressecção como fator prognóstico independente; a maioria dos artigos publicados anteriormente não tem escolhas metodológicas unânimes e as coortes de pacientes analisados não são fáceis de comparar. Para chegar a uma concordância unânime em relação ao valor prognóstico da margem de ressecção, seria necessário fazer metanálises em estudos que compartilham a definição da margem de ressecção, metodologia e escolhas terapêuticas pós-operatórias.

RESUMO

BACKGROUND: Allergic rhinitis is characterized by a remodeling of nasal epithelium. Since the Notch and TGF-ß signaling pathways are known to be involved in cell differentiation and remodeling processes and leptin adipokine has already been identified as a marker for homeostasis in human bronchial and nasal epithelial cells of asthmatics, roles played by these pathways have been investigated for chronic allergic rhinitis. METHODS: The leptin/leptin receptor expression has been investigated in a study with 40 biopsies from allergic (AR, n = 18) and non-allergic (C, n = 22) inferior turbinates, using immunohistochemistry, immunofluorescence staining and RT-PCR. In addition, extracts from in vitro samples prepared from primary cells of inferior turbinates as well as in vitro cultured human nasal epithelial RPMI 2650 cells (ATCC-CCL-30) were also tested for leptin expression and activation of the Notch-1 pathway. RESULTS: With regards to AR, in vivo expression levels of both leptin and its receptor significantly decreased in comparison to C. Furthermore, leptin receptor mRNA was significantly reduced in AR as compared to C. Immunofluorescence showed an apparent co-expression of leptin receptor with Notch-1, which was not seen with TGF-ß. In vitro, in primary turbinate epithelial cells, the expression of leptin receptor and Notch-1 significantly decreased in AR as compared to C. Moreover, in RPMI 2650 cells, leptin receptor expression was shown to be induced by Notch-1 ligand signaling. CONCLUSION: Thus, both the leptin and Notch-1 pathways appear to represent markers for epithelial homeostasis in allergic rhinitis.
