Background
Low skeletal muscle mass (SMM) is associated with postoperative complications, prolonged hospital stay, and short overall survival (OS) in surgical oncology. We aimed to investigate this ...association in patients undergoing total laryngectomy (TL).
Methods
A retrospective study was performed of patients undergoing TL. SMM was measured using CT or MRI scans at the level of the third cervical vertebra (C3).
Results
In all, 235 patients were included. Low SMM was observed in 109 patients (46.4%). Patients with low SMM had more pharyngocutaneous fistulas (PCFs) than patients with normal SMM (34.9% vs 20.6%; P = .02) and prolonged hospital stay (median, 17 vs 14 days; P < .001). In multivariate analysis, low SMM (hazards ratio, 1.849; 95% confidence interval, 1.202‐2.843) and high N stage were significant prognosticators of decreased OS.
Conclusion
Low SMM is associated with PCF and prolonged hospital stay in patients undergoing TL. Low SMM is an independent prognostic factor for shorter OS.

The 2019 novel coronavirus disease (COVID‐19) is a highly contagious zoonosis produced by SARS‐CoV‐2 that is spread human‐to‐human by respiratory secretions. It was declared by the WHO as a public ...health emergency. The most susceptible populations, needing mechanical ventilation, are the elderly and people with associated comorbidities. There is an important risk of contagion for anesthetists, dentists, head and neck surgeons, maxillofacial surgeons, ophthalmologists, and otolaryngologists. Health workers represent between 3.8% and 20% of the infected population; some 15% will develop severe complaints and among them, many will lose their lives. A large number of patients do not have overt signs and symptoms (fever/respiratory), yet pose a real risk to surgeons (who should know this fact and must therefore apply respiratory protective strategies for all patients they encounter). All interventions that have the potential to aerosolize aerodigestive secretions should be avoided or used only when mandatory. Health workers who are: pregnant, over 55 to 65 years of age, with a history of chronic diseases (uncontrolled hypertension, diabetes mellitus, chronic obstructive pulmonary diseases, and all clinical scenarios where immunosuppression is feasible, including that induced to treat chronic inflammatory conditions and organ transplants) should avoid the clinical attention of a potentially infected patient. Health care facilities should prioritize urgent and emergency visits and procedures until the present condition stabilizes; truly elective care should cease and discussed on a case‐by‐case basis for patients with cancer. For those who are working with COVID‐19 infected patients' isolation is compulsory in the following settings: (a) unprotected close contact with COVID‐19 pneumonia patients; (b) onset of fever, cough, shortness of breath, and other symptoms (gastrointestinal complaints, anosmia, and dysgeusia have been reported in a minority of cases). For any care or intervention in the upper aerodigestive tract region, irrespective of the setting and a confirmed diagnosis (eg, rhinoscopy or flexible laryngoscopy in the outpatient setting and tracheostomy or rigid endoscopy under anesthesia), it is strongly recommended that all health care personnel wear personal protective equipment such as N95, gown, cap, eye protection, and gloves. The procedures described are essential in trying to maintain safety of health care workers during COVID‐19 pandemic. In particular, otolaryngologists, head and neck, and maxillofacial surgeons are per se exposed to the greatest risk of infection while caring for COVID‐19 positive subjects, and their protection should be considered a priority in the present circumstances.

Background
Second primary tumors (SPTs) are a common cause of reduced life expectancy in patients treated for head and neck cancer (HNC). This phenomenon forms an area to be addressed during ...posttreatment follow‐up.
Methods
We conducted a systematic review of literature following PRISMA guidelines, from 1979 to 2019, to investigate incidence of SPTs, synchronous, and metachronous, in HNC population.
Results
Our review includes data of 456 130 patients from 61 articles. With a minimum follow‐up of 22 months, mean incidence of SPTs was 13.2% (95% CI: 11.56‐14.84): 5.3% (95% CI: 4.24‐6.36) for synchronous SPTs and 9.4% (95% CI: 7.9‐10.9) for metachronous SPTs. The most frequent site for SPTs was head and neck area, followed by the lungs and esophagus.
Conclusion
Although with wide variations between studies, the rate of SPTs in HNC patients is high. Given the impact in the prognosis, we must develop strategies for the early diagnosis of SPTs.

Head and neck squamous cell carcinoma (HNSCC) represents a group of tumors arising in the oral cavity, oropharynx, and larynx. Although HNSCC is traditionally associated with tobacco and alcohol ...consumption, a growing proportion of head and neck tumors, mainly of the oropharynx, are associated with Human Papilloma Virus (HPV). Recurrent/metastatic disease is characterized by dismal prognosis and there is an unmet need for the development of biomarkers for detection of early disease, accurate prediction of prognosis, and appropriate selection of therapy. Based on the REMARK guidelines, a variety of diagnostic and prognostic biomarkers are being evaluated in clinical trials but their clinical significance is doubtful. Herein, we will focus on biomarkers in HNSCC used in the clinical setting and we will illustrate their clinical relevance.
Background
The prognostic importance of intraparotid lymph node metastasis (P+) in patients with primary parotid gland carcinoma is unclear.
Methods
Nineteen retrospective and noncomparative cohort ...studies, published between 1992 and 2020, met the inclusion criteria and included 2202 patients for this systematic review.
Results
The pooled prevalence of the P in adult patients in the unselected studies was 24.10% (95% confidence interval = 17.95‐30.25). The number of P+ lymph nodes per patient was counted in only three studies and ranged from 1 to 11. The 5‐year recurrence‐free survival rate based on Kaplan‐Meier analysis varied from 83% to 88% in P− patients compared to 36% to 54% in P+ patients. The average hazard ratio for tumor recurrence in patients with P+ compared to P− was 2.67 ± 0.58.
Conclusions
P+ is an independent negative prognostic factor in primary parotid gland cancer and should be included into the treatment planning.

Background
Skeletal muscle mass (SMM) and chronic inflammation are associated with postoperative complications and survival.
Methods
Patients with head and neck cancer (HNC) undergoing microvascular ...free flap reconstruction were included. SMM and neutrophil‐to‐lymphocyte ratio (NLR) were measured and their association with treatment outcomes analyzed.
Results
Five hundred and fifty‐four patients were included. Predictors for complications were elevated NLR in all flaps (OR 1.5), low SMM in radial forearm flap (OR 2.0), and elevated NLR combined with low SMM in fibula flap surgery (OR 4.3). Patients with solely elevated NLR were at risk for flap‐related complications (OR 3.0), severe complications (OR 2.2), and when combined with low SMM for increased length of hospital stays (LOS) (+3.9 days). In early‐stage HNC, low SMM (HR 2.3), and combined elevated NLR with low SMM (HR 2.6) were prognostics for decreased overall survival.
Conclusions
SMM and NLR are predictive for poor outcomes in patients with HNC undergoing microvascular reconstruction.

Summary The incidence of distant metastasis in head and neck squamous cell carcinoma (HNSCC) is relatively low but remains a major determinant of prognosis and therefore an important factor in ...clinical decision making. The most frequently involved sites for distant metastasis are the lung (approximately 70% of cases), followed by bone and liver. There are often conflicting reports on which parameters are risk factors for distant metastasis, but the most important predictive factors appear to be the site of the primary tumor (hypopharynx in particular), advanced T- and N-classification, histological grade and the ability to achieve locoregional disease control. Metastasis results from a selection of tumor cells that have acquired the properties to withstand multiple and often unfavorable circumstances and settle in distant organs. Most of these processes involve interaction between tumor cells, their microenvironment and host factors. Increasing knowledge of the biology of distant metastasis may result in the development of diagnostic and therapeutic strategies targeted to this usually terminal stage for patients with HNSCC.

Background
The eighth international symposium for sentinel node biopsy (SNB) in head and neck cancer was held in 2018. This consensus conference aimed to deliver current multidisciplinary guidelines. ...This document focuses on the surgical aspects of SNB for oral cancer.
Method
Invited expert faculty selected topics requiring guidelines. Topics were reviewed and evidence evaluated where available. Data were presented at the consensus meeting, with live debate from panels comprising expert, nonexpert, and patient representatives followed by voting to assess the level of support for proposed recommendations. Evidence review, debate, and voting results were all considered in constructing these guidelines.
Results/Conclusion
A range of topics were considered, from patient selection to surgical technique and follow‐up schedule. Consensus was not achieved in all areas, highlighting potential issues that would benefit from prospective studies. Nevertheless these guidelines represent an up‐to‐date pragmatic recommendation based on current evidence and expert opinion.

Background
Low skeletal muscle mass (SMM) is an adverse prognostic factor for chemotherapy dose‐limiting toxicity (CDLT). In patients with locally advanced head and neck squamous cell carcinoma ...(HNSCC) undergoing chemoradiotherapy (CRT), low SMM is a predictor for CDLT. We aimed to validate these findings.
Methods
Consecutive LA‐HNSCC patients treated with primary CRT with high‐dose cisplatin were retrospectively included. SMM was measured on pre‐treatment CT‐imaging. A cumulative cisplatin dose below 200 mg/m2 was defined as CDLT.
Results
One hundred and fifty three patients were included; 37 (24.2%) experienced CDLT, and 84 had low SMM (54.9%). Patients with low SMM experienced more CDLT than patients with normal SMM (35.7% vs. 10.1%, p < 0.01). Low SMM (OR 3.99 95% CI 1.56–10.23, p = 0.01) and an eGFR of 60–70 ml/min (OR 5.40 95% CI 1.57–18.65, p < 0.01) were predictors for CDLT.
Conclusion
Pre‐treatment low SMM is associated with CDLT in LA‐HNSCC patients treated with primary CRT. Routine SMM assessment may allow for CDLT risk assessment and treatment optimization.
