Abstract
Head and neck squamous cell carcinoma (HNSCC) is well known as a serious health problem worldwide, especially in low-income countries or those with limited resources, such as most countries in Latin America. International guidelines cannot always be applied to a population from a large region with specific conditions. This study established a Latin American guideline for care of patients with head and neck cancer and presented evidence of HNSCC management considering availability and oncologic benefit. A panel composed of 41 head and neck cancer experts systematically worked according to a modified Delphi process on (1) document compilation of evidence-based answers to different questions contextualized by resource availability and oncologic benefit regarding Latin America (region of limited resources and/or without access to all necessary health care system infrastructure), (2) revision of the answers and the classification of levels of evidence and degrees of recommendations of all recommendations, (3) validation of the consensus through two rounds of online surveys, and (4) manuscript composition. The consensus consists of 12 sections: Head and neck cancer staging, Histopathologic evaluation of head and neck cancer, Head and neck surgery-oral cavity, Clinical oncology-oral cavity, Head and neck surgery-oropharynx, Clinical oncology-oropharynx, Head and neck surgery-larynx, Head and neck surgery-larynx/hypopharynx, Clinical oncology-larynx/hypopharynx, Clinical oncology-recurrent and metastatic head and neck cancer, Head and neck surgery-reconstruction and rehabilitation, and Radiation therapy. The present consensus established 48 recommendations on HNSCC patient care considering the availability of resources and focusing on oncologic benefit. These recommendations could also be used to formulate strategies in other regions like Latin America countries.

Abstract
PURPOSE The use of tracheoesophageal prostheses has become the gold standard in vocal rehabilitation of patients undergoing total laryngectomy. However, this method also has limitations, such as the need for frequent replacement of prostheses due to leakage or other complications. We have designed a study to access the clinical profile of patients using tracheoesophageal prostheses as vocal rehabilitation after total laryngectomy and to determine the average rate of changes, as well as the main causes of prostheses replacement. METHODS A retrospective cohort study was performed based on patients who underwent rehabilitation with voice prostheses after total laryngectomy between 2008 and 2017. RESULTS The sample consisted of 93 patients and 432 vocal prostheses replacement events. The median change of prostheses per patient was 210.25 days, (range 57.33 to 651.50). The most frequent cause of prostheses replacement was leakage through the prostheses, 218 (50.46%). Lower level of education was associated to higher prostheses replacement rate. CONCLUSION The results of this study show that the median of prostheses durability is higher than that presented in the literature, the main cause of replacement was protheses leakage and that low educational level is associated to higher replacement rate.

Abstract
BACKGROUND Metastatic lymph node involvement influences therapy decisions and serves as a prognostic indicator in oral squamous cell carcinoma (OSCC). However, many early-stage patients with clinically negative lymph nodes exhibit no metastasis upon surgical staging. This study aimed to identify differentially expressed miRNAs capable of distinguishing pathologically positive (pN+) from negative (pN0) nodes in OSCC patients without clinical evidence of lymph node metastases (cN0). METHODS Expression levels of 798 miRNAs were assessed in tumor samples from 10 pN+ and 10 pN0 patients using the Nanostring nCounter platform. Validation was performed in an independent cohort of 15 pN+ and 24 pN0 patients through RT-qPCR. RESULTS Eight miRNAs exhibited differential expression between pN0 and pN+ patients. Notably, hsa-miR-99a-5p demonstrated high sensitivity and specificity in predicting patients at higher risk of positive lymph nodes. CONCLUSIONS These findings highlight hsa-miR-99a-5p as a potential biomarker for detecting lymph node metastasis in primary OSCC tumors.

Abstract
Abstract
Introduction The prevalence of oropharyngeal squamous cell carcinoma (OSCC) related to Human Papillomavirus (HPV) is rising in the whole world.
Objective To access the prevalence and temporal trend of HPV infection in oropharyngeal cancer by analyzing the expression of the p16 protein.
Methods We conducted a transversal study in a Brazilian reference oncology center. The sample consisted of 254 patients with OSCC. The analyzed period was from 2013 to 2017. All patients underwent p16 immunohistochemistry analysis.
Results The overall prevalence of HPV-related OSCC was of 31.9%. During the analyzed period, we observed a trend of increasing rates of OSCC that marked positive for p16 immunohistochemistry. The annual prevalence of p16-positive cases was of 20.6% in 2013, 23.9% in 2014, 33.3% in 2015, 38.3% in 2016, and 34.2% in 2017. Most of the patients were stage III and IV (84%). Female patients (odds ratio [OR] = 2.43; 95% confidence interval [CI]: 1.003–5.888; p = 0.049) and younger patients (OR = 2.919; 95%CI: 1.682–5.067; p < 0.005) were associated with a higher risk of HPV-related OSCC. Tobacco consumption had a proportional lower risk of HPV-related OSCC (OR = 0.152; 95%CI: 0063–0.366; p < 0.005).
Conclusion We observed an increasing prevalence of HPV-related OSCC in a specialized cancer hospital in Brazil.

Abstract
BACKGROUND Tobacco or human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas (OPSCC) represent different clinical and epidemiologic entities. This study investigated the prevalence of HPV-positive and HPV-negative OPSCC in a reference cancer hospital in Brazil and its association with clinical and demographic data, as well as its impact on overall survival. METHODS HPV infection was determined by p16-IHC in pre-treatment formalin-fixed paraffin-embedded samples from all patients with OPSCC diagnosed at Barretos Cancer Hospital between 2008 and 2018. The prevalence of HPV-positive cases and its temporal trend was assessed, and the association of clinical and demographic data with HPV infection and the impact on patient overall survival was evaluated. RESULTS A total of 797 patients with OPSCC were included in the study. The prevalence of HPV-associated tumors in the period was 20.6% [95% confidence interval, 17.5-24.0] with a significant trend for increase of HPV-positive cases over the years (annual percentage change = 12.87). In a multivariate analysis, the variables gender, level of education, smoking, tumor sublocation, region of Brazil, and tumor staging had a significant impact in HPV positivity, and a greater overall survival (OS) was observed in HPV-positive patients (5-year OS: 47.9% vs. 22.0%; P = 0.0001). CONCLUSIONS This study represents the largest cohort of Brazilian patients with OPSCC characterized according to HPV status. We report significant differences in demographics and clinical presentation according to HPV status, and an increasing trend in prevalence for HPV-induced tumors. IMPACT These findings can potentially contribute to a better stratification and management of patients as well as assist in prevention strategies.

Abstract
We sought to evaluate the evolution of the nutritional status of patients with advanced cancer of the upper aerodigestive tract undergoing surgical treatment (SURG) or organ preservation protocol (OP). Evaluations were conducted at the beginning and end of treatment, including weight, body composition and Patient-Generated Subjective Global Assessment (PG-SGA). Each group was comprised of 29 patients. Initially, malnutrition rates were 65.5% and 51.7% in the SURG and OP groups, respectively. At the end, the values went to 55.1% in SURG and 79.3% in OP. In the OP, there was a reduction in weight (P = 0.001), fat mass (P = 0.006), fat free mass (P = 0.002), and muscle mass (P = 0.005) and an increase in scores of the PG-SGA (P = 0.008). The same was not observed in SURG, except for the weight decrease (P = 0.025). Malnutrition was prevalent in both treatment groups and patients in OP were at greater risk of nutritional decline.

Abstract
Background The evolution of radiotherapy over recent decades has reintroduced the hypofractionation for many tumor sites with similar outcomes to those of conventional fractionated radiotherapy. The use of hypofractionation in locally advanced head and neck cancer (LAHNC) has been already used, however, its use has been restricted to only a few countries. The aim of this trial was to evaluate the safety and feasibility of moderate hypofractionated radiotherapy (HYP-RT) with concomitant cisplatin (CDDP). Methods This single-arm trial was designed to evaluate the safety and feasibility of HYP-RT with concomitant CDDP in LAHNC. Stage III and IV patients withnonmetastatic disease were enrolled. Patients were submitted to intensity modulatedradiation therapy, which comprised 55 Gy/20 fractions to the gross tumor and44–48 Gy/20 fractions to the areas of subclinical disease. Concomitant CDDPconsisted of 4 weekly cycles of 35 mg/m2. The primary endpoints were the treatment completion rate and acute toxicity. Results Twenty patients were enrolled from January 2015 to September 2016, and 12 (60%) were classified as unresectable. All patients completed the total dose of radiotherapy, and 19 patients (95%) received at least 3 of 4 cycles of chemotherapy. The median overall treatment time was 29 days (27–34). Grade 4 toxicity was reported twice (1 fatigue and 1 lymphopenia). The rates of grade 3 dermatitis and mucositis were 30% and 40%, respectively, with spontaneous resolution. Nasogastric tubes were offered to 15 patients (75%) during treatment; 4 patients (20%) needed feeding tubes after 2 months, and only 1 patient needed a feeding tube after 12 months. Conclusion HYP-RT with concomitant CDDP was considered feasible for LAHNC, and the rate of acute toxicity was comparable to that of standard concomitant chemoradiation. A feeding tube was necessary for most patients during treatment. Further investigation of this strategy is warranted. Trial registration ClinicalTrials, NCT03194061. Registered 21 Jun 2017 – Retrospectively registered.

Abstract
BACKGROUND The purpose of this phase II trial was to evaluate the tolerability, safety, and efficacy of a non-5-fluorouracil (5-FU)-based induction chemotherapy followed by chemoradiotherapy (CRT) for patients with locally advanced head and neck squamous cell carcinoma (HNSCC). METHODS Sixty patients with stage III to IV HNSCC were treated with induction paclitaxel and cisplatin (TP; paclitaxel 175 mg/m(2) and cisplatin 80 mg/m(2) , 3 cycles) followed by CRT (cisplatin 100 mg/m(2) ; D1, 22, and 43 of radiotherapy). RESULTS Fifty-six patients (93.3%) completed 3 cycles of induction TP (no treatment-related deaths), 52 (86.7%) completed definitive CRT per protocol (adverse event [AE] grade ≥2 in 53.3%). The overall response rate after induction TP was 82.5% for patients with resectable disease and 55.5% for unresectable disease (p = .023), and complete response (CR) rate after CRT was 70.0% for patients with resectable disease and 30.0% for unresectable disease (p = .005). CONCLUSION Induction TP followed by cisplatin based-CRT was well-tolerated, safe, and had high overall response rate in selected patients with locally advanced HNSCC. © 2015 Wiley Periodicals, Inc.

Abstract
Fat-forming solitary fibrous tumor (SFT) is a rare variant of solitary fibrous tumor, a mesenchymal fibroblastic neoplasia with a particular branching hypervascular pattern. This tumor is usually classified as benign and only very few fat-forming SFTs with malignant histologic features have been reported. We report a histologically malignant fat-forming solitary fibrous tumor in a 61-year-old man, located in his neck. Ultrasonography examination was first performed showing a heterogeneous lesion, predominantly hyperechoic, with sound beam attenuation, containing two hypoechoic solid nodules. Magnetic resonance imaging and computed tomography examinations demonstrated a heterogeneous and predominantly adipose mass, containing post contrast enhancing solid nodules and thin septations. Treatment consisted of total removal of the lesion. Histologically, the tumor showed hypercellularity, numerous mitoses and cytological atypia, fulfilling the criteria for malignancy. The patient had no metastasis. This rare tumor may be confused with other fat-containing lesions on imaging examinations, mainly liposarcoma.
