RESUMO
Abstract Introduction: Supratracheal laryngectomy has been described as a surgical procedure for glottic or supraglottic cancer extending to the subglottic region and/or involving the cricoarytenoid joint, aiming to preserve laryngeal function (breathing, phonation and swallowing), without diminishing locoregional cancer control. The choice of supracricoid laryngectomy in these cases could result in a high risk of compromised resection margins. Objective: To determine the safety, viability, adequacy of surgical margins and the supratracheal laryngectomy results for intermediate and advanced laryngeal cancer by reviewing the results at three different institutions in Brazil. Methods: This is a retrospective study that analyzed the charts of 29 patients submitted to supratracheal laryngectomy from October 1997 to June 2017. The type of laryngectomy performed was classified according to the European Laryngological Society classification for horizontal laryngectomies. Early and late results were evaluated. Survival rates (overall, specific, disease-free and total laryngectomy-free survival) were calculated. The mean follow-up time was 44 months. Results: Of the 29 patients submitted to supratracheal laryngectomy, 25 had no previous treatment. One patient (3.4%) had compromised margins. Four patients (13.8%) had recurrence. Of these, three had local recurrence and one had regional recurrence. Five patients (17.2%) required a total laryngectomy, two due to ruptured pexy and three due to local recurrence. Four of these patients (80%) achieved a successful total procedure. Four patients (13.8%) died, two due to postoperative complications and two due to recurrence. Overall, specific, disease-free and total laryngectomy-free survival at 5 years were, respectively, 82.1%; 88.2%; 83.0% and 80.2%. Conclusion: Selected patients with intermediate and advanced laryngeal cancer may benefit from supratracheal laryngectomy, that resulted in total laryngectomy-free survival and specific survival of 80.2% and 88.2%, respectively.
Resumo Introdução: A laringectomia supratraqueal tem sido descrita como um procedimento cirúrgico com objetivo de preservar a função da laringe (respiração, fonação e deglutição), sem prejuízo no controle oncológico locorregional, para câncer glótico ou supraglótico com extensão à subglote e/ou envolvimento da articulação cricoaritenóidea. A opção pela laringectomia supracricoide nesses casos poderia resultar em grande risco para margens de ressecção comprometidas. Objetivo: Determinar a segurança, viabilidade, adequação das margens cirúrgicas e os resultados da laringectomia supratraqueal para o câncer de laringe intermediário e avançado através da revisão dos resultados de três instituições distintas no Brasil. Método: Estudo retrospectivo, com análise dos prontuários de 29 pacientes submetidos à laringectomia supratraqueal, de outubro de 1997 a junho de 2017. O tipo de laringectomia realizada foi classificado de acordo com a classificação da Sociedade Laringológica Europeia para laringectomias horizontais. Foram avaliados os resultados precoces e tardios. As taxas de sobrevida (global, específica, livre de doença e livre de laringectomia total) foram calculadas. O tempo médio de seguimento foi 44 meses. Resultados: Dos 29 pacientes submetidos à laringectomia supratraqueal, 25 não tinham tratamento prévio. Um paciente (3,4%) teve margens comprometidas. Quatro pacientes (13,8%) recidivaram. Desses, três tiveram recidiva local e um apresentou recidiva regional. Cinco pacientes (17,2%) necessitaram de totalização da laringectomia, duas por ruptura da pexia e três por recidiva local. Quatro desses pacientes (80%) obtiveram sucesso na totalização. Quatro pacientes (13,8%) foram a óbito, dois por complicações pós-cirúrgicas e dois por recidiva. As sobrevidas global, específica, livre de doença e livre de laringectomia total em 5 anos foram, respectivamente, 82,1%; 88,2%; 83,0% e 80,2%. Conclusão: Pacientes selecionados com câncer intermediário e avançado de laringe podem ser beneficiados com laringectomia supratraqueal, que ofereceu sobrevida livre de laringectomia total e sobrevida específica de 80,2% e 88,2%, respectivamente.

BACKGROUND: Supracricoid laryngectomy with cri-cohyoidoepiglottopexy (CHEP) is a conservative surgical procedure indicated in selected cases of advanced glottic carcinoma. METHODS: This study is a review of our experience with 43 patients with T3/T4 glottic squamous cell carcinoma who underwent CHEP in our institution. All but two patients underwent selective neck dissections. All patients were staged on the basis of the 2002 TNM classification. Rates of recurrence and death were estimated by the Kaplan-Meier method. RESULTS: The 5-year disease-specific survival and 5-year relapse-free survival rates were 78% and 83%, respectively. Neck metastases were found in three patients. Cartilage invasion occurred in 11 cases. The average length of hospital stay was 5.7 days. The mean time of enteral feeding tube was 33.8 days, and the mean time for tracheotomy was 29.6 days. Overall, normal swallowing was achieved in 74.4% of patients. Eleven patients had mild and major complications. Laryngeal stenosis emerged as the most frequent major complication. Three patients (6.9%) had local recurrences. Two patients (4.6%) had neck metastases. CONCLUSIONS: On the basis of this study, over a 7-year period with 43 patients with advanced glottic cancer, a successful on-cologic outcome is confirmed.

OBJECTIVES: To evaluate the results of standardized treatment of esthesioneuroblastoma (ENB) during a 17-year period and to identify pertinent factors for clinical outcome. DESIGN: Review of clinical and radiographic data and retrospectively staging ENB according to 3 staging systems: Kadish, Biller, and Dulguerov and Calcaterra. SETTING: Hospital do Cancer I-Instituto Nacional de Cancer, Rio de Janeiro, Brazil. PATIENTS: Thirty-six patients with histologically confirmed ENB treated between January 1, 1983, and December 31, 2000; 35 fulfilled study inclusion criteria. INTERVENTIONS: Treatment included gross tumor resection through a transfacial approach with postoperative radiotherapy (RT) in 11 patients, craniofacial resection (CFR) and postoperative RT in 7, exclusive RT in 14, CFR alone in 1, and a combination of chemotherapy and RT in 2. Histopathological slides were reviewed and graded using the Hyams staging system. Analysis of prognostic factors was performed. MAIN OUTCOME MEASURES: Evaluation of survival rates using the Kaplan-Meier method. Analysis of prognostic factors carried out with the Fisher exact test and the log-rank test. RESULTS: Analysis of survival showed that the Kadish classification best predicted disease-free survival (P =.046). The presence of regional and distant metastases adversely affected prognosis (P<.001 and P =.01, respectively). Craniofacial resection plus postoperative RT provided a better 5-year disease-free survival rate (86%) compared with the other therapeutic options used (P =.05). The 5-year disease-specific survival rate was 64% and 43% for the low- and high-grade tumors, respectively (P =.20). Disease-free survival for this cohort of 35 patient was 46% and 24% at 5 and 10 years, respectively. Overall survival was 55% and 46% at 5 and 10 years of follow-up, respectively. CONCLUSIONS: The development of cervical nodal metastases and distant metastases had a significant adverse impact on prognosis. The value of the Kadish staging system was confirmed in our study, significantly correlating with prognosis. Tumor grade according to the Hyams staging system also seems to be an important factor in determining prognosis for tumor recurrence and survival. Aggressive multimodality therapeutic strategies, particularly CFR and adjuvant RT, yielded the best treatment outcome.
