Malnutrition, in patients with solid tumors, is associated with a worse clinical outcome and about 40% of patients affected by head and neck cancers (HNC) are malnourished at the time of cancer diagnosis. We investigated the potential benefit of a standardized immunonutritional protocol (INP) to patients with HNC receiving major ablative surgery.An observational study was conducted enrolling 199 patients: 50 treated with the INP and 149 with standard enteral nutrition. Complication rates, need for medications, and costs were considered as outcomes.INP played a protective role in development of major surgical complications (OR 0.23, p = 0.023), albumin administration (RR 0.38, p = 0.018), and antibiotic duration (p 0.001) and is cost-effective in patients with moderate or severe malnutrition (-6083€ and -11 988€, p 0.05).Our study supports the utility of INP, and accurate nutritional screening can help to identify malnourished patients who would receive the most benefits from this protocol.

Purpose Non-squamous cell carcinoma (non-SCC) accounts for about 5% of laryngeal malignancies. Survival data are limited, and consensus on management principles is lacking. The present study reviews our experience in the surgical treatment of non-metastatic non-SCC of the larynx and compares oncological and functional outcomes in a cohort of patients affected by traditional SCC. Methods We collected data on 592 patients affected by laryngeal neoplasms. Univariate and multivariable survival analyses were performed using Cox proportional-hazards models; survival estimates were reported by hazard ratios (HR) with 95% confidence intervals (CI), and survival curves were established with the Kaplan–Meier method. Results We identified 326 patients affected by untreated SCC, while 21 had non-SCC histotypes. The non-SCC cohort was composed of 5 soft tissue sarcomas, 8 chondrosarcomas, 2 adenoid cystic carcinomas, 2 neuroendocrine carcinomas, 2 solitary fibrous tumors, 1 Kaposi’s sarcoma, and 1 malignant peripheral nerve sheath tumor. Overall survival and disease-specific survival were not significantly different according to histology (p = 0.6 and p = 0.349, respectively). The non-SCC group showed an increased risk of recurrence (HR 5.87; CI95 2.15–16.06; p p = 0.31) was found at multivariable analysis between the two groups in total laryngectomy-free survival with an organ preservation rate over 5 years of 81% for the non-SCC histologies. Conclusion Non-SCC is a broad spectrum pathology, but generalized laryngeal surgical management principles are still feasible and it is possible to identify patients amenable to conservative surgical treatment without affecting survival.

Objectives Lymph node burden has been proposed to estimate the cumulative adverse effect of nodal metastasis. In this study, a meta-analysis was conducted to evaluate the prognostic value of lymph node burden in oral cavity squamous cell carcinoma. Study designs Systemic review and meta-analysis. Methods PubMed, EMBASE and the Cochrane Library as well as manual searches were performed until April 2020. The adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) of overall survival, disease-specific survival, and disease-free survival were extracted and pooled. Results Eleven included studies were published between 2009 and 2019. The cumulative number of patients was 20,607 (range 35-14,554). Extranodal extension was adjusted or evaluated in all of the studies. The meta-analysis indicated that a higher lymph node burden was significantly related to worse overall survival (HR 2.62, 95% CI 2.12-3.25), worse disease-specific survival (HR 3.14, 95% CI 1.85-5.33) and worse disease-free survival (HR 2.30, 95% CI 1.62-3.26). The highest hazard ratio was observed when the cutoff value was 3 for overall survival, 3 for disease-specific survival, and 4 for disease-free survival. The hazard ratio showed an upward trend before the cutoff value of 3 but no significant incremental change when the cutoff exceeded 3. Conclusions In oral squamous cell carcinoma, lymph node burden is an independent prognosticator for survival outcomes. However, more prospective or high-quality studies are required to determine the optimal cutoff. Level of evidence NA Laryngoscope, 2021.

Purpose In 2016, the European Laryngological Society (ELS) proposed a classification for vascular changes occurring in glottic lesions as visible by narrow band imaging (NBI), based on the dichotomic distinction between longitudinal vessels (not suspicious) and perpendicular ones (suspicious). The aim of our study was to validate this classification assessing the interobserver agreement and diagnostic test performance in detecting the final histopathology. Methods A retrospective study was carried out by reviewing clinical charts, preoperative videos, and final pathologic diagnosis of patients submitted to transoral microsurgery for laryngeal lesions in two Italian referral centers. In each institution, two physicians, independently re-assessed each case applying the ELS classification. Results The cohort was composed of 707 patients. The pathologic report showed benign lesions in 208 (29.5%) cases, papillomatosis in 34 (4.8%), squamous intraepithelial neoplasia (SIN) up to carcinoma in situ in 200 (28.2%), and squamous cell carcinoma (SCC) in 265 (37.5%). The interobserver agreement was extremely high in both institutions (k = 0.954, p k = 0.880, p Conclusion The ELS classification for NBI vascular changes of glottic lesions is a highly reliable tool whose systematic use allows a better diagnostic evaluation of suspicious laryngeal lesions, reliably distinguishing benign ones from those with a diagnosis of papillomatosis, SIN or SCC, thus paving the way towards confirmation of the optical biopsy concept.

Objective The first-line therapeutic approach for oral cavity squamous cell carcinoma (OCSCC) is complete surgical resection. Preoperative assessment of depth of invasion (cDOI) is crucial to plan the surgery. Magnetic resonance (MR) and intraoral ultrasonography (IOUS) have been shown to be useful tools for assessment of DOI. The present analysis investigates the accuracy of MR and IOUS in evaluating DOI in OCSCC compared to histological evaluation (pDOI). Materials and methods Forty-nine previously untreated patients with cT1-T3 OCSCC were reviewed. Nine patients were staged with MR alone, 10 with IOUS alone, and 30 with both MR and IOUS. Results Mean difference between cDOIMR and pDOI values of 0.2 mm (95% CI − 1.0–1.3 mm) and between cDOIIOUS and pDOI of 0.3 mm (95% CI − 1.0–1.6 mm). Spearman R between cDOIMR and pDOI was R = 0.83 and between cDOIIOUS and pDOI was R = 0.76. Both radiological techniques showed high performance for the correct identification, with the optimum cut-off of 5 mm, of patients with a pDOI ≥ 4 mm and amenable to a neck dissection, with an AUC of 0.92 and 0.82 for MR and IOUS, respectively. Conclusion Both examinations were valid approaches for preoperative determination of DOI in OCSCC, although with different cost-effectiveness profiles and indications.

Rhinogenic headache (RH) is a widespread pain syndrome but its pathogenesis and treatment are still unclear. Some authors recognize a correlation between RH and mucosal contact points or some other sinonasal anatomical variations. The authors conducted a retrospective case-control study to analyze the correlation between radiological findings and clinical symptoms.One hundred-nineteen adults with Para-Nasal Sinuses Computed Tomography (PNS-CT) scans were included: 64 patients who have originally undergone PNS-CT scan as part of rhinogenic headache workup (Group A), and 55 controls in whom PNS-CT scans were obtained for other purposes (Group B). All subjects were asked to report their symptoms using a headache scoring system. PNS-CT scans of all subjects were analyzed for presence of mucosal contact points, middle turbinate concha bullosa (MTCB) and frontoethmoidal cells.The most common anatomical abnormality found in our series was MTCB, reported in 60.9% of patients in Group A and 41.8% of those in Group B. A statistically significant prevalence was found in Group A compared to Group B regarding the presence of MTCB (P = 0.037) and Type II (P = 0.016) and Type III (P = 0.039) frontoethmoidal cells. No statistically significant difference (P >0.05) was found between Group A and Group B regarding the presence of mucosal contact points at each site.Multiple anatomical variations in nasal and paranasal sinuses may cause a rhinogenic headache with different characteristics. Some of these, such as concha bullosa of middle turbinate or type II and III Kuhn cells, have shown a significant association with rhinogenic headache. No statistically significant association was found between presence of headache and mucosal contact points and type I and IV frontal cells. These findings can be very helpful for the surgeons that want to deal with the treatment of RH.

Introduction The Union for International Cancer Control–American Joint Committee on Cancer TNM staging system for glottic squamous cell carcinoma (SCC) includes different types of lesions defined by the involvement of specific subsites in each T category. Our study aims to identify different subcategories according to tumor local extension and determine oncologic outcomes after treatment by transoral laser microsurgery (TLM) alone. Methods We retrospectively evaluated 410 patients affected by previously untreated pT1-pT3 glottic SCC treated by TLM alone from January 2005 to December 2015 at the Departments of Otorhinolaryngology—Head and Neck Surgery, Universities of Genoa and Brescia, Italy. All patients had at least 2 years of follow-up. Clinical, radiological, surgical, and histopathological data were reviewed and tumors divided into six subcategories: I, pT1a not involving the anterior commissure (AC); II, pT1b involving the AC; III, pT2 extending superficially to the supraglottis or the subglottis; IV, pT2 infiltrating the vocal muscle; V, pT3 involving the anterior paraglottic space; VI, pT2 or pT3 with vertical extension across the AC with/without involvement of the pre-epiglottic space. Recurrence-free survival (RFS), local control with laser alone (LCL), and organ preservation (OP) were defined as the primary oncologic outcomes. Results The 2, 5, and 10-year RFS for the entire series were 85.7, 80.3, and 73.8%, LCL rates 93.8, 92.1, and 89.6%, and OP rates 96.8, 95.9, and 93.5%, respectively. However, when comparing the rates of RFS, LCL, and OP for each subcategory, important differences emerged. In particular, subcategories V and VI showed a significantly increased risk of local recurrence [hazard ratio (HR) = 9.2 and 13.3, respectively]. These subcategories also had a significantly reduced probability to achieve LCL (HR: 73.6 and 93.5, respectively) and OP (HR: 6.4 and 8.1, respectively). Conclusion The present classification in subcategories allows introducing the concept of a three-dimensional map of isoprognostic zones in glottic SCC treated by TLM alone as a useful tool in its management by a multidisciplinary tumor board.
