Association between tonsillectomy and risk of oropharyngeal cancer: a systematic review

Fri, 03 May 2024 00:00:00 +0000

Objective. Studies have demonstrated that tonsillectomy may alter the risk of oropharyngeal cancer (OPC). We systematically reviewed the evidence and pooled data to examine such an association.
Methods. PubMed, Embase, and Scopus were searched up to 25th April 2023. Studies reporting an association between tonsillectomy and oropharyngeal cancer risk at any site were included.
Results. Five studies were eligible. All examined the risk of tonsillar and base of the tongue (BOT) cancer with prior history of tonsillectomy. On meta-analysis of the data, prior history of tonsillectomy was associated with a significantly decreased risk of tonsillar cancer. The second meta-analysis showed that history of tonsillectomy did not significantly alter the risk of BOT cancer. However, after exclusion of one study, the results showed an increased risk of BOT cancer with a history of tonsillectomy.
Conclusions. The scarce data available in the literature suggests that tonsillectomy may reduce the risk of tonsillar cancer but does not alter the risk of BOT cancer. Further studies are needed to explore the association between tonsillectomy and the risk of OPC.

Post-operative intensity-modulated vs 3D conformal radiotherapy after conservative surgery for laryngeal tumours of the supraglottic region: a dosimetric analysis on 20 patients

Tue, 30 Apr 2024 00:00:00 +0000

Objective. To perform a dosimetric comparison between intensity modulated radiotherapy (IMRT) and 3D conformal radiotherapy in patients with locally advanced (stage III and IV) tumours of the supraglottic region treated with conservative surgery and post-operative radiotherapy.
Methods. An in-silico plan using a 3D conformal shrinking field technique was retrospectively produced for 20 patients and compared with actually delivered IMRT plans. Eighteen structures (arytenoids, constrictor muscles, base of tongue, floor of mouth, pharyngeal axis, oral cavity, submandibular glands and muscles of the swallowing functional units [SFU]) were considered.
Results. IMRT allowed a reduction of maximum and mean doses to 9 and 14 structures, respectively (p < .05).
Conclusions. IMRT achieved a reduction of unnecessary dose to the remnant larynx and the majority of surrounding SFUs. Further prospective analyses and correlations with functional clinical outcomes are required to confirm these dosimetric findings.

The role of artificial intelligence in training ENT residents: a survey on ChatGPT, a new method of investigation

Tue, 30 Apr 2024 00:00:00 +0000

Objective. The primary focus of this study was to analyze the adoption of ChatGPT among Ear, Nose, and Throat (ENT) trainees, encompassing its role in scientific research and personal study. We examined in which year ENT trainees become involved in clinical research and how many scientific investigations they have been engaged in.
Methods. An online survey was distributed to ENT residents employed in Italian University Hospitals.
Results. Out of 609 Italian ENT trainees, 181 (29.7%) responded to the survey. Among these, 67.4% were familiar with ChatGPT, and 18.9% of them used artificial intelligence as a tool for research and study. In all, 32.6% were not familiar with ChatGPT and its functions. Within our sample, there was an increasing trend of participation by ENT trainees in scientific publications throughout their training.
Conclusions. ChatGPT remains relatively unfamiliar and underutilised in Italy, even though it could be a valuable and efficient tool for ENT trainees, providing quick access for study and research through both personal computers and smartphones.

Changes in Management of Head and Neck Malignancies during the COVID-19 Pandemic

Tue, 30 Apr 2024 00:00:00 +0000

Objective. Despite multiple studies from high-income countries, reports from low- and middle-income countries on the impact of COVID-19 on head and neck cancer care remain sparse. This study aimed to assess the effects of the COVID-19 pandemic on head and neck cancer patients at a tertiary reference centre in Bosnia and Herzegovina.
Methods. We included 228 patients with malignant head and neck tumours evaluated and treated between January 1, 2019, and December 31, 2021. Patient demographics, histological characteristics, and treatment modalities were retrospectively obtained and compared between the pre-pandemic period (pre-COVID-19 group) and the period after the implementation of COVID-19 restrictive measures (COVID-19 group).
Results. Patients were significantly older during the COVID-19 pandemic. In particular, 63 patients (44.7%) were under 65 and 78 (55.3%) were 65 or older, while in the pre- COVID-19 period, 53 patients (60.9%) were under 65 and 34 (39.1%) were 65 or older (p = 0.017). The pre-COVID-19 and COVID-19 groups did not significantly differ regarding other patient- and tumour characteristics, or primary treatment modalities.
Conclusions. During the COVID-19 pandemic, significantly fewer patients were under 65 at the time of initial work-up, potentially reflecting the more enhanced disease-related anxiety of the younger population. Future studies are warranted to address this population’s specific educational and psychological needs to ensure appropriate cancer care.

Thyroid cartilage infiltration in advanced laryngeal cancer: prognostic implications and predictive modelling

Fri, 29 Dec 2023 00:00:00 +0000

Objective. Detection of laryngeal cartilage invasion is of great importance in staging of laryngeal squamous cell carcinoma (LSCC). The role of prognosticators in locally advanced laryngeal cancer are still widely debated. This study aimed to assess the impact of volume of thyroid cartilage infiltration, as well as other histopathologic variables, on patient survival.
Materials and methods. We retrospectively analysed 74 patients affected by pT4 LSCC and treated with total laryngectomy between 2005 and 2021 at the Department of Otorhinolaryngology – Head and Neck Surgery of the University of Brescia, Italy. We considered as potential prognosticators histological grade, perineural (PNI) and lympho-vascular invasion (LVI), thyroid cartilage infiltration, and pTN staging. Pre-operative CT or MRI were analysed to quantify the volume of cartilage infiltration using 3D Slicer software.
Results. The 1-, 3-, and 5-year disease free survivals (DFS) were 76%, 66%, and 64%, respectively. Using machine learning models, we found that the volume of thyroid cartilage infiltration had high correlation with DFS. Patients with a higher volume (> 670 mm³) of infiltration had a worse prognosis compared to those with a lower volume.
Conclusions. Our study confirms the essential role of LVI as prognosticator in advanced LSCC and, more innovatively, highlights the volume of thyroid cartilage infiltration as another promising prognostic factor.

Dysphagia characteristics at FEES examination in post-extubation patients with COVID-19

Thu, 06 Jun 2024 14:04:25 +0000

Objective. The aims of this study was to analyse fibreoptic endoscopic evaluation of swallowing (FEES) findings in tube-fed patients with coronavirus disease 2019 (COVID-19).
Methods. Seventeen patients who had been intubated during intensive care unit (ICU) stay were enrolled. Pooling of secretions, dysphagia phenotype, penetration/aspiration and residue after swallow were assessed through FEES. The Functional Oral Intake Scale (FOIS) scores were also collected. Patients with significant swallowing impairment were evaluated again after 2 weeks.
Results. All patients were tube-fed at enrollment. According to the FEES results, 7 started total oral feeding with at least one consistency. The more common dysphagia phenotypes were propulsive deficit and delayed pharyngeal phase. Pooling of secretions, penetration/ aspiration, and residue after swallow were frequently documented. A significant improvement in FOIS scores was found during the second FEES examination.
Conclusions. Swallowing impairment in patients with severe COVID-19 after discharge from the ICU is characterised by propulsive deficit and delayed pharyngeal phase. Most of these patients required feeding restrictions even if feeding abilities seem to improve over time.

Validation and reliability of the Italian version of the Self-reported Mini Olfactory Questionnaire (Self-MOQ)

Tue, 30 Apr 2024 00:00:00 +0000

Objective. Olfactory dysfunction (OD) represents a frequent complaint in general population and especially in patients with chronic sinonasal diseases. The aim of this study was the cross-cultural adaptation and validation of the Self-reported Mini Olfactory Questionnaire (Self-MOQ) into Italian.
Methods. One hundred fifty patients affected by chronic sinonasal diseases and reporting hyposmia were enrolled. Other 150 normosmic subjects without inflammatory or neoplastic sinonasal disorders were used as a control group. The Short-form 36 (SF-36) questionnaire was used for clinical validity.
Results. Cronbach’s alpha coefficient was 0.825. The test-retest reliability was excellent. The good correlation between the Self-MOQ and the Visual Analogue Scale scores (p < 0.05) demonstrated the construct validity of the questionnaire. The Self-MOQ was able to distinguish between subjects with or without OD (p < 0.05). Higher Self-MOQ score was found in case of nasal obstruction and posterior rhinorrhoea (p < 0.05). Self-MOQ showed significant correlation with SF-36 general health, SF-36 role functioning/physical, and SF- 36 pain (p < 0.05).
Conclusions. The Italian version of the Self-MOQ showed good internal consistency, testretest reliability, construct, and clinical validity.

Vertical saccades during horizontal head impulses: a sign of posterior semicircular canal hypofunction

Francesco dD'Onofrio, Letizia Neri, Giampiero Neri — Fri, 03 May 2024 00:00:00 +0000

Objective. We describe an uncharacteristic vestibular-ocular reflex (VOR) pattern, studied by video head impulse tests (VHIT) in patients suffering from unilateral isolated posterior semicircular canal (PSC) hypofunction. In these patients, we found an upward sliding of the eyes, followed by an oblique downward catch-up saccade during horizontal head impulse to the healthy side.
Methods. We present a retrospective study of all VHIT exams presenting isolated PSC hypofunction between May 2020 and November 2022.
Results. We found 37 patients, which led to the discovery of such incongruent eye movement in 19 cases; their gain data are shown and compared to the remaining 18 cases in which such an anomaly was absent. A control group of 31 healthy subjects was recruited to define the reference criteria for VHIT gain values. The correlation between the amplitude of the vertical saccade and the relative functional imbalance of the vertical semicircular canals was studied.
Conclusions. We have observed that in approximately half of the subjects with isolated CSP deficiency, there is a VOR anomaly. A possible pathophysiological explanation of the unbalanced effect of vertical semicircular canal stimulation of a labyrinth during horizontal head thrust toward the opposite side is proposed. The planar incongruity of the response of the VOR described here appears more evident at the onset of the CSP deficit. Current VHIT systems do not detect this incongruent eye reflex. They can lead to an error in gain evaluation (pseudo-deficit) of the lateral semicircular canal of the healthy side and problems in performing the test (trace rejected). In the future, software for VHIT should take into account the possibility of non-coplanar ocular responses to cephalic stimuli.
