RESUMO
PURPOSE: The neck management in early-stage cN0 supraglottic cancer represents an argument of debate. The aim of our study is to evaluate the oncological and functional outcomes in patients with early-stage cN0 supraglottic carcinoma treated with a wait-and-see policy for the neck. MATERIALS AND METHODS: Retrospective monocentric cohort study in a referral cancer care center. We collected a consecutive sample of patients from 2000 to 2020 with Squamous Cell Carcinoma of the supraglottis without clinical evidence of nodal metastases (cN0), surgically treated with Transoral Surgery (Laser or Robotic) without neck dissection. From 316 supraglottic cancer we finally selected 66 eligible participants that met all inclusion criteria. RESULTS: Sixty-six patients (M 75.8 % vs F 24.2 %), median age 65.8 years (IQR 60.9, 70.5). The most common subsite was the epiglottis (62.1 %). Tumor stage distribution was as follows: 35 % cT1, 53 % cT2, 15.2 % cT3. Neither deaths nor major treatment-related complications were reported after surgery. The median follow-up was 62 months. For oncological outcomes, we evaluated 56 patients (10 excluded for adjuvant radiotherapy): 5-year overall survival rate 87 % (CI 95 %: 73.1-94), disease- specific survival rate 95.3 % (CI 95 %: 82-98.8) and neck recurrence-free survival rate 87 % (CI 95 %: 73.1-94). Six patients developed neck recurrence, with a median time of 13 months. CONCLUSIONS: Supraglottic carcinoma has been historically associated to a considerable risk of occult metastasis. However, in early-stage cases data are still inconclusive. Our results suggest that in such patients a wait-and-see policy does not impact negatively on survival outcomes, while granting the reduced morbidity associated to a minimally invasive surgical approach.

PURPOSE: Salvage surgery is still the best therapeutic option for resectable recurrent oropharyngeal squamous cell carcinoma (rOPSCC). Transoral robotic surgery may potentially reduce the morbidity of standard open approaches. The aim of the study is to present oncological and functional outcomes of a monocentric experience in salvage transoral robotic surgery. METHODS: We performed a single-center retrospective analysis of patients submitted to transoral robotic salvage surgery with or without neck dissection for cT1-3 rOPSCC. We investigated complication rate, survival outcomes (Overall Survival, Disease Specific Survival, Loco-Regional Recurrence Free Survival) and functional outcomes (tracheal tube and/or gastrostomy dependence). RESULTS: Sixty-one patients were included in the analysis. No major complications or perioperative deaths were recorded. The estimated 2-year OS was 76.7%, DSS 81.8% and LRRFS 50.5%. In multivariable analysis rpT, PNI (perineural infiltration) and HPV-positivity were significantly associated with LRRFS (Hazard Ratios: T3 vs T1 6.43, PNI yes vs no 4.19, HPV+ yes vs no 2.63). At last follow up, 97% of patients were tracheal tube-free, while 93% were gastrostomy-free. CONCLUSION: Transoral robotic salvage surgery is a successful treatment in selected patients affected by rOPSCC because it grants good oncologic and functional outcomes.

PURPOSE: Radiomics is an emerging field that utilizes quantitative features extracted from medical images to predict clinically meaningful outcomes. Validating findings is crucial to assess radiomics applicability. We aimed to validate previously published magnetic resonance imaging (MRI) radiomics models to predict oncological outcomes in oral tongue squamous cell carcinoma (OTSCC). MATERIALS AND METHODS: Retrospective multicentric study on OTSCC surgically treated from 2010 to 2019. All patients performed preoperative MRI, including contrast-enhanced T1-weighted (CE-T1), diffusion-weighted sequences and apparent diffusion coefficient map. We evaluated overall survival (OS), locoregional recurrence-free survival (LRRFS), cause-specific mortality (CSM). We elaborated different models based on clinical and radiomic data. C-indexes assessed the prediction accuracy of the models. RESULTS: We collected 112 consecutive independent patients from three Italian Institutions to validate the previously published MRI radiomic models based on 79 different patients. The C-indexes for the hybrid clinical-radiomic models in the validation cohort were lower than those in the training cohort but remained > 0.5 in most cases. CE-T1 sequence provided the best fit to the models: the C-indexes obtained were 0.61, 0.59, 0.64 (pretreatment model) and 0.65, 0.69, 0.70 (posttreatment model) for OS, LRRFS and CSM, respectively. CONCLUSION: Our clinical-radiomic models retain a potential to predict OS, LRRFS and CSM in heterogeneous cohorts across different centers. These findings encourage further research, aimed at overcoming current limitations, due to the variability of imaging acquisition, processing and tumor volume delineation.
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.

BACKGROUND: Radiomics represents an emerging field of precision-medicine. Its application in head and neck is still at the beginning. METHODS: Retrospective study about magnetic resonance imaging (MRI) based radiomics in oral tongue squamous cell carcinoma (OTSCC) surgically treated (2010-2019; 79 patients). All preoperative MRIs include different sequences (T1, T2, DWI, ADC). Tumor volume was manually segmented and exported to radiomic-software, to perform feature extraction. Statistically significant variables were included in multivariable analysis and related to survival endpoints. Predictive models were elaborated (clinical, radiomic, clinical-radiomic models) and compared using C-index. RESULTS: In almost all clinical-radiomic models radiomic-score maintained statistical significance. In all cases C-index was higher in clinical-radiomic models than in clinical ones. ADC provided the best fit to the models (C-index 0.98, 0.86, 0.84 in loco-regional recurrence, cause-specific mortality, overall survival, respectively). CONCLUSION: MRI-based radiomics in OTSCC represents a promising noninvasive method of precision medicine, improving prognosis prediction before surgery.

Laryngeal carcinoma represents one-third of all head and neck cancers and is burdened by significant morbidity and mortality for advanced-stage disease. Surgical treatments, including Open Partial Horizontal Laryngectomy (OPHL), are often followed by long-lasting swallowing rehabilitation and more rarely, persistent dysphagia. Some authors reported single cases, successfully treated with fat injection of the base of tongue, but nowadays, a standardized technique has never been described so far. We provide a step-by-step technique description of the trans-cervical lipofilling of the base of the tongue (BOT) under local anaesthesia in a case series of three patients. The functional results have been evaluated with a videofluoroscopic study of deglutition and Penetration-Aspiration Score. The procedure was well tolerated; all patients were discharged after 24 hours without any majorcomplications. After six months, all patients had a steady improvement in swallowing. During follow-up, the videofluoroscopic study of deglutition confirmed a sensitive amelioration of the Penetration-Aspiration Score and an empowered base of tongue retropulsion. Finally, the lipofilling of the BOT under local anaesthesia showed to be a feasible, and reproducible procedure, for dysphagia after OPHLs.
RESUMO
The use of sternocleidomastoid muscle flap has firstly been described in 1909. In spine surgery, it is usually reserved in the cases of revision after anterior cervical spine procedures. The aim of this article is to introduce its usage as prophylactic measure in cases at high risk of iatrogenic fistula formation. The procedure consists of three main steps: sternocleidomastoid isolation, flap design and harvesting, and flap fixation. The use of a surgical anchor allows a better adherence to the plate preventing hematoma formation. The use of SCM smart flap in primary anterior cervical spine surgery as a prophylactic method could be considered a safe and feasible procedure in patients with a high risk of iatrogenic fistulas.

A 46-year-old man was referred to our ear, nose and throat department after the accidental discovery of a large retrotracheal mass. In order to obtain the diagnosis and to plan treatment he underwent a full battery of tests (CT, MRI, blood tests, hormonal assays, ultrasounds, thyroid scintigraphy, urine tests and fine-needle aspiration of the mass), but none of these was able to define the true nature of such cervical mass. Only after surgical excision and histological evaluation, it was diagnosed as an exceptional case of giant non-functional parathyroid adenoma.
