    A REVIEW OF LARYNGEAL CANCER MANAGEMENT
    (2020) CARVALHO, I. T. De; RAMOS, D. M.; PREARO, F. M. L.; LIM, F.; WAN, B. A.; SILVA, M. F.
    Laryngeal cancer treatment in Latin America has unique characteristics related to the exposure to risk factors, socioeconomic level of the population and access to health systems. This chapter aims to perform a review of the literature produced in the last 20 years, including 39 studies, with prospective randomized studies, case series and case reports, on the treatment of early, advanced and metastatic laryngeal cancer, featuring literature produced in Latin America. In general, patterns of care adopted in Latin countries are very similar to that adopted in other countries. © 2020 by Nova Science Publishers, Inc. All rights reserved.

    Neutrophil-to-lymphocyte ratio as a prognostic factor for pharyngocutaneous fistula after total laryngectomy
    (2018) AIRES, F. T.; DEDIVITIS, R. A.; V, M. A. Kulcsar; RAMOS, D. M.; CERNEA, C. R.
    The role of systemic inflammatory response as a prognostic factor has been proposed in a variety of cancers. The purpose of this study was to investigate the prognostic value of the pretreatment neutrophil-to-lymphocyte ratio (NLR) in the incidence of pharyngocutaneous fistula (PCF) in patients who underwent total laryngectomy. We conducted a retrospective cohort analysis of 141 patients with squamous cell carcinoma of larynx who underwent total laryngectomy from 2009 to 2015. The incidence of PCF was 49.6%. A higher risk of 23% was observed among patients with NLR > 2.5 for the occurrence of PCF (p = 0.007). Patients with laryngeal squamous cell carcinoma who present elevated values in the ration > LR> (> 2.5) presented a higher risk of developing pharyngocutaneous fistula in the postoperative setting of total laryngectomy.

    IntroductionThe aim of this study is to assess the impact of lymph node ratio (LNR) and number of positive lymph nodes (NPLN) on mortality and recurrence rates in patients with laryngeal squamous cell carcinoma. Materials and methodsWe conducted a retrospective multicenter international study involving 24 Otorhinolaryngology-Head and Neck Surgery divisions. Disease-specific survival (DSS) and disease-free survival (DFS) were evaluated as the main outcomes. The curves for DSS and DFS according to NPLN and LNR were analyzed to identify significant variations and establish specific cut-off values. Results2507 patients met the inclusion criteria. DSS and DFS were significantly different in the groups of patients stratified according to LNR and NPLN. The 5-year DSS and DFS based on LNR and NPLN demonstrated an improved ability to stratify patients when compared to pN staging. ConclusionOur data demonstrate the potential prognostic value of NPLN and LNR in laryngeal squamous cell carcinoma.

    Lymph node density as a predictive factor for worse outcomes in laryngeal cancer
    (2020) PETRAROLHA, Silvia; DEDIVITIS, Rogerio; MATOS, Leandro; RAMOS, Daniel; KULCSAR, Marco
    Background The lymph node density (LND) is the number of positive metastatic lymph nodes divided by the total number of dissected lymph nodes. The purpose of this study was to evaluate LND as a prognostic factor in patients with laryngeal squamous cell carcinoma (SCC). Methods The study included 186 patients with laryngeal SCC submitted to laryngeal surgical treatment with neck dissection between January 2009 and December 2016. Clinical-pathological variables were assessed, as well as the cut-off point for LND. Results LND value was calculated considering pN+ (LND = 0.060). The Kaplan-Meier curve (log-rank) related to cumulative survival demonstrated that patients with LND >= 0.060 had a higher mortality rate than those with LND < 0.060, presenting a more aggressive form of the disease, with earlier recurrence. However, only the LND >= 0.060 group had impact on both disease-free survival and overall survival. Conclusion The LND proved to be an important index in the prognostic evaluation of larynx SCC patients having a direct relationship with disease recurrence. Patients with LND >= 0.060 should be considered for adjuvant therapy.

    Malignant solitary fibrous tumor of the thyroid: a case-report and review of the literature
    (2014) ALVES FILHO, Wellington; MAHMOUD, Renata Regina da Graca Lorencetti; RAMOS, Daniel Marin; ARAUJO-FILHO, Vergilius Jose Furtado de; LIMA, Patricia Picciarelli de; CERNEA, Claudio Roberto; BRANDAO, Lenine Garcia
    Solitary fibrous tumor (SFT) is an uncommon spindle-cell neoplasm that most often involves the pleura, rarely occurring in extra-thoracic locations. Twenty-six cases of SFT arising in the thyroid gland have been described. We report a case of a 60-year-old woman presenting an 8-month history of enlargement of the neck associated with dysphagia. The patient underwent a right hemithyroidectomy and SFT of the thyroid was diagnosed. Immunohistochemistry showed positivity for CD34 marker, and the high number of mitoses and the presence of cellular atypia suggested that the tumor was malignant. To our knowledge, this is the second case of malignant SFT of the thyroid gland ever reported. Due to the rarity of these tumors, the indication of adjuvant therapy and prognosis are uncertain. Long-term follow-up after surgical resection seems to be advisable.

    Efficacy of pectoralis major muscle flap for pharyngocutaneous fistula prevention in salvage total laryngectomy: A systematic review
    (2016) GUIMARAES, Andre Vicente; AIRES, Felipe Toyama; DEDIVITIS, Rogerio Aparecido; KULCSAR, Marco Aurelio Vamondes; RAMOS, Daniel Marin; CERNEA, Claudio Roberto; BRANDAO, Lenine Garcia
    Background. The role of pectoralis major muscle flap (PMMF) in reducing the rate of pharyngocutaneous fistula after salvage total laryngectomy has not been clearly established. The purpose of this study was to evaluate the impact of PMMF in reducing pharyngocutaneous fistula rates after total laryngectomy. Methods. The analyzed intervention was the use of a PMMF after total laryngectomy. Results. Pharyngocutaneous fistula occurred in 230 cases (global incidence, 30.9%). In the group of patients who underwent PMMFs, there were 49 cases of pharyngocutaneous fistula, compared with 181 cases in the control group. There was a 22% decreased risk of pharyngocutaneous fistula incidence in the PMMF group (p < .001). Patients who underwent a PMMF had lower risk of pharyngocutaneous fistula compared with the control group (p = .008). There were no changes when only patients who underwent total laryngectomy (p < .001) and those who underwent total pharyngolaryngectomy (p = .007) were separately assessed. Conclusion. Prophylactic use of PMMF decreases the incidence of pharyngocutaneous fistula after salvage total laryngectomy. (C) 2015 Wiley Periodicals, Inc.
