The psychosocial needs of head and neck cancer patients: a multicenter study.

INTRODUCTION: Cancer is among the most frequent pathologies and a major cause of death and disability. Scientific research and surgeons focus mainly on aspects relating to etiopathogenesis, diagnosis, and treatment, but often neglect the psychological needs of patients and related social factors. The aim of this study is to investigate the psychological and social needs of patients affected by head and neck cancer to improve patient management and achieve more empathetic care. MATERIALS AND METHODS: The Need Evaluation Questionnaire (NEQ) was administered to adult patients who had to undergo surgery in 4 Italian tertiary head and neck cancer centers the day before the operation. RESULTS: 188 patients affected by stage I-IV head and neck tumors were enrolled. The main needs expressed by patients fall under the categories of either "information and dialogue", (64.3% more information about future conditions, 50% more information about treatments, 45% more information about the diagnosis, 44% more reassurance) or "spiritual support" (50% need to talk to someone who had the same experience as them). CONCLUSIONS: Common methods of explaining diagnosis, treatment, and prognosis have proven unsatisfactory to patients and most also require more psychosocial support. This highlights the need to implement interventions and activities that are increasingly geared toward supporting the psychological and relational aspects of the care journey.

Blood Markers Predicting Clinically Occult Lymph Node Metastasis in Head and Neck Squamous Cell Carcinoma.

INTRODUCTION: The presence of cervical lymph node metastases is an unfavorable prognostic factor in head and neck squamous cell carcinoma (HNSCC) and a potential cause of treatment failure. Occult lymph node metastasis occurs in approximately 15-20% of HNSCC patients with a clinically negative neck (cN0), greatly impacting on their prognosis. The present study aimed to investigate the role of pre-treatment peripheral blood markers in predicting clinically occult cervical lymph node metastasis. METHODS: This multicenter, retrospective study was performed in a cohort of 472 patients diagnosed with cN0 HNSCC who underwent up-front surgery. Baseline neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic inflammatory marker (SIM), and systemic immune-inflammation index (SII) were calculated from available blood parameters. RESULTS: Oro-hypopharyngeal and oral cancers, locally advanced stage, moderately (G2), and poorly (G3) differentiated grade were associated with an increased risk of pathological lymph node involvement. NLR, LMR, PLR, SIM, and SII were significantly associated at multivariable analysis. NLR >2.12 was the most reliable at predicting occult lymph node metastasis (OR = 5.22; 95% CI: 2.14-12.75). We describe a predictive score integrating cancer site, local stage, and NLR which is effective at predicting positive lymph node pathological status. CONCLUSIONS: The present study provides evidence that pre-treatment peripheral blood markers, in particular NLR, represent reliable predictors of clinically occult cervical lymph node metastasis in cN0 HNSCC. Therefore, the present study provides a novel useful predictive score for directing the elective management of the neck in patients with cN0 HNSCC.

Compartmental surgery for T4b oral squamous cell carcinoma involving the masticatory space.

PURPOSE OF REVIEW: This review aims to describe the oncological outcomes of T4b oral squamous cell carcinomas (OSCC) with masticatory space involvement as well as the surgical approaches that are able to achieve compartmental 'en bloc' resection of these lesions. RECENT FINDINGS: The masticatory space is subdivided into infra-notch and supra-notch spaces according to the axial plane passing through the mandibular notch between the coronoid process and the condyle neck. Compartmental resection for T4b OSCC with masticatory space invasion can be successfully achieved via purely external approaches or combining external and transnasal endoscopic routes. Infra-notch T4b OSCC showed survival outcomes comparable to T4a OSCC, thus prompting treatment with curative intent. SUMMARY: Compartmental resection of the masticatory space is technically feasible with comprehensive control of tumour margins. Use of a transnasal endoscopic anterior route within a multiportal approach may provide better control of margins at the level of the pterygo-maxillary fissure. Equivalent survival outcomes between T4a and infra-notch T4b OSCC are reported. Thus, a downstaging of the latter to T4a is advisable and compartmental surgery of such advanced lesions could be considered as a first-line treatment option in selected patients.

Lateral hypopharyngectomy with laryngeal preservation reconstructed with inlay fascio-cutaneous free flaps: clinical and functional outcomes.

Objective: Lateral hypopharyngectomy (LH) is one of the organ-preservation surgical strategies available for treatment of selected naïve early squamous cell carcinoma (SCC), as well as for rarer non-SCC tumours and persistent/recurrent/second primaries after chemoradiation of the lateral wall of the piriform sinus. Its reconstructive methods have been the subject of different approaches without a general consensus. The aim of the present study is to describe a retrospective series of LH reconstructed by inlay fascio-cutaneous free flaps, reporting on oncological and functional outcomes. Methods: Patients who underwent LH at the Department of Otorhinolaryngology - Head and Neck Surgery of the University of Brescia, Italy, between 2017 and 2023 were retrospectively reviewed. Clinical history, tumour histotype, postoperative complications, functional, and oncological outcomes were collected. Results: Seven patients (6 males, 1 female) were included. In all, 29% had a naïve neoplasm, while 71% had recurrent disease. The final histology included 3 SCC, 2 synovial sarcomas, one liposarcoma, and one single-site mucosal metastasis from cutaneous melanoma. Negative margins were achieved in 6 patients (86%). All patients had swallowing rehabilitation by speech therapists and were able to safely eat a free diet at discharge, except for one who needed a percutaneous endoscopic gastrostomy to support nutritional oral intake. After a mean follow-up of 34.3 months, all patients except one are alive. Conclusions: Our study showed that, in selected cases, it is possible to radically remove lateral hypopharyngeal tumours with laryngeal preservation and free flaps inlay reconstruction, with a low rate of complications and acceptable functional and oncological results.

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

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.

Transoral laser exoscopic surgery of the larynx: state of the art and comparison with traditional transoral laser microsurgery.

Objective: To evaluate the efficacy of transoral laser exoscopic surgery (TOLES) in a unicentric series of patients affected by benign and malignant glottic and supraglottic lesions, and compare outcomes with those of transoral laser microsurgery (TOLMS). Methods: To demonstrate the non-inferiority of TOLES in terms of operative time, margin status and complication rates, we compared outcomes of 93 patients treated by TOLES between July 2021 and July 2023 with those of a match-paired group of 107 historical patients treated by TOLMS. To perform a multiparametric ergonomic evaluation of TOLES vs TOLMS, we used observational methods for biomechanical overload risk assessment and wearable technologies comparing 15 procedures with TOLES vs a paired match of 13 surgeries performed with TOLMS by the same surgeon. Results: No significant differences were found in terms of surgical duration, positive margins, or complications between TOLES and TOLMS. Ergonomics assessment by inertial measurement units and electromyographic surface electrodes demonstrated a reduced biomechanical overload with TOLES compared to TOLMS. Conclusions: The many advantages of TOLES, such as its superior didactic value, better digital control of light even through small-bored laryngoscopes, improved binocular vision, and increase in surgical performance by 3 or 4-hand techniques, are difficult to be quantified. In contrast, its non-inferiority in terms of oncological results and better ergonomics compared to TOLMS are demonstrated herein.

Treatment and outcomes of minor salivary gland cancers of the larynx and trachea: a systematic review.

Objectives: Malignant minor salivary glands carcinomas (MiSGC) of the larynx and trachea are rare tumours and published evidence is sparse. We conducted a systematic review to describe shareable treatment strategies and oncological outcomes of these neoplastic entities. Methods: Full text English manuscripts published from January 1st 2000 to December 14th 2022 were included. Data on demographics, treatments and outcomes were collected. A pooled analysis of 5-year overall survival (OS) was performed. Results: Seventeen articles and 365 patients met the inclusion criteria. The most common subsites involved were subglottic and distal trachea. Adenoid cystic carcinoma was, by far, the most frequent histotype. The first-choice treatment strategy was surgery (86.8%), while adjuvant treatments were delivered in 57.4% of patients. Only 12.9% were treated with definitive radiotherapy with/without chemotherapy. The mean follow-up was 68.3 months. One hundred nine (34.9%) deaths were recorded and 62.4% were cancer-related. Five-year OS ranged from 20% to 100% and, at pooled analysis, it was 83% (range, 78-87%). Conclusions: In case of MiSGC of the larynx and trachea, surgery remains the mainstay of treatment. Adjuvant treatments are frequently delivered. Survival estimates are good overall, but highly heterogeneous.

Hemicricoidectomy with modified rotational thyro-crico-tracheal anastomosis: a newborn in the family of crico-tracheal resection and anastomosis techniques.

Objective: The aim of the present study is to describe our novel surgical technique of hemicricoidectomy and reconstruction with modified rotational thyro-crico-tracheal anastomosis for the treatment of non-squamous cell subglottic tumours. The procedure has been defined as Type E crico-tracheal resection and anastomosis (CTRA) following the University of Brescia (C)TRA classification introduced elsewhere. Methods: A detailed anatomical step-by-step dissection was reproduced and illustrated on a cadaveric laryngo-tracheal specimen. Moreover, oncological and functional outcomes of the first 5 patients who underwent Type E CTRA at our Institution between October 2016 and September 2022 are described. Results: Three patients underwent Type E CTRA for cricoid chondrosarcoma (CS) and 2 patients for subglottic adenoid cystic carcinoma (ACC). No post-operative complication was reported. All patients maintained intact oral intake and an intelligible voice at discharge. All but one patient with obstructive sleep apnoea hypopnea syndrome and lung comorbidity were successfully decannulated before discharge. At the last follow-up (April 2023), one patient experienced local recurrence of CS that was still amenable to conservative treatment by transoral debulking, while the remaining patients were free of disease. Conclusions: With the proper indications, Type E CTRA is a feasible and effective conservative surgical technique for selected non-squamous cell subglottic tumours.

Instance segmentation of upper aerodigestive tract cancer: site-specific outcomes.

Objective: To achieve instance segmentation of upper aerodigestive tract (UADT) neoplasms using a deep learning (DL) algorithm, and to identify differences in its diagnostic performance in three different sites: larynx/hypopharynx, oral cavity and oropharynx. Methods: A total of 1034 endoscopic images from 323 patients were examined under narrow band imaging (NBI). The Mask R-CNN algorithm was used for the analysis. The dataset split was: 935 training, 48 validation and 51 testing images. Dice Similarity Coefficient (Dsc) was the main outcome measure. Results: Instance segmentation was effective in 76.5% of images. The mean Dsc was 0.90 ± 0.05. The algorithm correctly predicted 77.8%, 86.7% and 55.5% of lesions in the larynx/hypopharynx, oral cavity, and oropharynx, respectively. The mean Dsc was 0.90 ± 0.05 for the larynx/hypopharynx, 0.60 ± 0.26 for the oral cavity, and 0.81 ± 0.30 for the oropharynx. The analysis showed inferior diagnostic results in the oral cavity compared with the larynx/hypopharynx (p < 0.001). Conclusions: The study confirms the feasibility of instance segmentation of UADT using DL algorithms and shows inferior diagnostic results in the oral cavity compared with other anatomic areas.

The role of endothelium in the vasorelaxant effects of the essential oil of Ocimum gratissimum in aorta and mesenteric vascular bed of rats.

This study investigated the endothelium-dependent vasorelaxant effects of the essential oil of Ocimum gratissimum (EOOG) in aortas and mesenteric vascular beds isolated from rats. EOOG (3-300 µg/mL) relaxed the tonic contractions induced by phenylephrine (0.1 µmol/L) in isolated aortas in a concentration-dependent manner in both endothelium-containing and endothelium-denuded preparations. This effect was partially reversed by L-NAME (100 µmol/L) but not by indomethacin (10 µmol/L) or TEA (5 mmol/L). In mesenteric vascular beds, bolus injections of EOOG (30, 50, 100, and 300 ng) decreased the perfusion pressure induced by noradrenaline (6 µmol/L) in endothelium-intact preparations but not in those treated with deoxycholate. L-NAME (300 µmol/L) but not TEA (1 mmol/L) or indomethacin (3 µmol/L) significantly reduced the vasodilatory response to EOOG at all of the doses tested. Our data showed that EOOG exerts a dose-dependent vasodilatory response in the resistance blood vessels of rat mesenteric vascular beds and in the capacitance blood vessel, the rat aorta. This action is completely dependent on endothelial nitric oxide (NO) release in the mesenteric vascular beds but only partially dependent on NO in the aorta. These novel effects of EOOG highlight interesting differences between resistance and capacitance blood vessels.

Artificial intelligence in clinical endoscopy: Insights in the field of videomics.

Artificial intelligence is being increasingly seen as a useful tool in medicine. Specifically, these technologies have the objective to extract insights from complex datasets that cannot easily be analyzed by conventional statistical methods. While promising results have been obtained for various -omics datasets, radiological images, and histopathologic slides, analysis of videoendoscopic frames still represents a major challenge. In this context, videomics represents a burgeoning field wherein several methods of computer vision are systematically used to organize unstructured data from frames obtained during diagnostic videoendoscopy. Recent studies have focused on five broad tasks with increasing complexity: quality assessment of endoscopic images, classification of pathologic and nonpathologic frames, detection of lesions inside frames, segmentation of pathologic lesions, and in-depth characterization of neoplastic lesions. Herein, we present a broad overview of the field, with a focus on conceptual key points and future perspectives.
