Simple Summary: Treatment recommendations for head and neck cancer need to be disseminated worldwide becoming available through societies/authors scientific reports and websites with warning updates. This scoping review identifies and compares the worldwide clinical practice guidelines for treating oral, oropharynx, and larynx cancer. We verified the absence of guidelines in Latin American and Oceanian countries, as well as the inequalities between countries/continents, with a similar pattern of recommendations among low-income countries and in developed ones. Recommendations for surgery, radiotherapy, and chemotherapy may differ according to country/institution access and resources Head and neck cancer (HNC) treatments have been based on single or multimodal therapies with surgery, radiotherapy (RT), chemotherapy, and immunotherapy. However, treatment recommendations among countries may differ due to technological/human resources and usual local practices. This scoping review aims to identify, compare, and map the clinical practice guidelines (CPGs) for treating squamous cell carcinoma (SCC) of the oral cavity, oropharynx, and larynx worldwide. A search strategy on global CPGs for HNC was performed by using five electronic databases and grey literature. CPGs were selected for inclusion using EndNote-20 and Rayyan online software. No language or publication date restrictions were applied. The results were analyzed descriptively considering the most updated CPG version. In total, 25 CPGs covering the head and neck region (10), the larynx (7), the oral cavity (5), and the oropharynx (3), were found in 13 geographical regions, and 19 were developed by medical societies from 1996 to 2023. Surgery and RT remain the main modalities for early-stage HNC, with surgery preferred in low-resource countries, and RT in selected cases, especially in the larynx/oropharynx aiming to achieve a cure with organ preservation. Human papillomavirus infection for oropharyngeal SCC is not tested in some Asian countries and there is still no consensus to treat p16-positive cases differently from p16-negative. Recommendations for larynx preservation vary according to facilities in each country, however, individualized choice is emphasized. Inequality across countries/continents is evident, with a similar pattern of recommendations among developed as well as developing ones. No CPGs were found in Latin America as well as Oceania countries, where the incidence of HNC is high and limitations of access to treatment may be encountered. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to assess the clinical value of 18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) after the first cycle of induction chemotherapy (IC) in locally advanced squamous cell carcinoma of the head and neck (LASCCHN). Methods and findings: A prospective, single-arm, single center study was performed, with patients enrolled between February 2010 and July 2013.Patients (n = 49) with stage III/IVA–B LASCCHN who underwent IC with taxanes, cisplatin, and fluorouracil were recruited. Staging procedures included loco-regional and chest imaging, endoscopic examination, and PET/CT scan. On day 14 of the first cycle, a second PET/CT scan was performed. Patients with no early increase in regional lymph node maximum 18F-FDG standard uptake value (SUV), detected using 18F-FDG PET/CT after first IC had better progression-free survival (hazard ratio (HR) = 0.18, 95%, confidence interval (CI) 0.056–0.585; p = 0.004) and overall survival (HR = 0.14, 95% CI 0.040–0.498; p = 0.002), and were considered responders. In this subgroup, patients who achieved a reduction of ≥ 45% maximum primary tumor SUV experienced improved progression-free (HR = 0.23, 95% CI 0.062–0.854; p = 0.028) and overall (HR = 0.11, 95% CI 0.013–0.96; p = 0.046) survival. Conclusions: These results suggest a potential role for early response evaluation with PET/CT examination in patients with LASCCHN undergoing IC. Increased regional lymph node maximum SUV and insufficient decrease in primary tumor uptake predict poorer outcomes. [ABSTRACT FROM AUTHOR]

Background Quality assessment is a major tool for evaluation of health care delivery. In head and neck surgery, the University of Texas MD Anderson Cancer Center (MD Anderson) has defined quality standards by publishing benchmarks. Methods We conducted an analysis of 360 head and neck surgeries performed at the AC Camargo Cancer Center (AC Camargo). The procedures were stratified into low-acuity procedures (LAPs) or high-acuity procedures (HAPs) and outcome indicators where compared to MD Anderson benchmarks. Results In the 360 cases, there were 332 LAPs (92.2%) and 28 HAPs (7.8%). Patients with any comorbid condition had a higher incidence of negative outcome indicators ( p = .005). In the LAPs, we achieved the MD Anderson benchmarks in all outcome indicators. In HAPs, the rate of surgical site infection and length of hospital stay were higher than what is established by the benchmarks. Conclusion Quality assessment of head and neck surgery is possible and should be disseminated, improving effectiveness in health care delivery. © 2015 Wiley Periodicals, Inc.
