Earl y glottic cancer can be effectively treated with radiation or surgery, but recurrence is a possibility when using any of the treatment modalities. Aim:To assess the outcome of radiotherapy as initial treatment in the control of squamous cell carcinoma of vocal cord (T1) and the effectiveness of salvage surgery (endoscopic or open) after treatment failure. Materials and Methods:A retrospective study was based on the analysis of medical records from 43 patients with T1 squamous cell carcinoma of the glottis, radiotherapy as initial treatment and follow-up period of five years. Results:The rate of recurrence after radiotherapy was 30.2% of the cases, mean diagnosis interval was 29.5 months. As an option for salvage treatment, patients underwent open partial laryngectomy or endoscopic surgery with control rates of 77.7% and 25% respectively. Conclusion:Our cases showed high rates of recurrence after radiotherapy and open partial laryngectomy was more effective for the salvage surgery. Braz J Otorhinolaryngol. 2011;77(3):299-302.

Clinical and epidemiological study of the squamous cell carcinoma of the base of the tongue Resumo / SummaryInt rodução: A evolução assintomática e a disseminação precoce justifica a análise de variáveis determinantes do prognóstico do carcinoma espinocelular de base de língua (CEC). Objetivo: estudo clínico-epidemiológico de pacientes portadores CEC de base de língua. Forma de Estudo: Retrospectivo . Material e Método: 290 pacientes com carcinoma epidermóide de base de língua (1977 a 2000), 259 homens (89,3%) e 31 mulheres (10,7%) -relação 8:1 -, 237 brancos (81,7%), 51 negros (17,6%) e 2 amarelos (0,7%) -relação 5:1. Houve predomínio da 6ª década (41,0%), 5ª e 7ª (22,7%), 8ª (3,4%) e 9ª (1,7%). Estas variáveis foram relacionadas com a profissão, hábitos e vícios (tabagismo e etilismo), estadiamento TNM, sintoma inicial, tempo entre o diagnóstico e o início do tratamento. Para análise estatística, utilizamos testes não paramétricos: Wilcoxon (tempo de consumo de álcool e fumo para cada paciente), Kruskal Wallis (álcool e fumo e o estadiamento TNM para cada paciente), Kappa (concordância entre o grau de consumo do álcool e fumo para cada estádio TNM e para cada grupo de pacientes segundo a ocupação), e Mc Nemar (complementar ao Kappa -determinação das frequências acima e abaixo da diagonal de concordância). Como nível de rejeição da hipótese de nulidade, fixou-se como valor significante 0,05 ou 5%. Resultados: Predominaram pacientes ligados à indústria (36,6%) seguido de comerciários e liberais (34,5%), agricultores (7,9%) e aposentados (7,3%). Houve predomínio do grupo dos 30 aos 59 anos (61,1%) e do tempo de queixa de até 180 dias (62,0%). A odinofagia (37,2%) foi a queixa principal, linfonodo metastático (21,8%), disfagia (14,5%), ferida na língua (9,0%), rouquidão (6,9%) corpo estranho (4,8%), otalgia (3,4%) outras (2,0%). Quanto aos hábitos, etilismo e tabagismo (83,8%), tabagismo (10,3%), etilismo (1,4%) e nenhum (4,5%). Houve relação de 9:1 dos estádios III e IV (avançados) em relação ao I e II (iniciais), sendo que todos I, II e IV eram tabagistas e ou etilistas, unanimidade não encontrada nos casos III, IVa, IVb e IVc (23,1%, 53,8% e 23,1% respectivamente). Quanto ao parâmetro T, 241 (83,1%) eram T 3 e T 4 e 49(16,9%) eram T 1 e T 2 . Quanto ao N, 61(21,6%) eram N 0 , 39(13,4%) N1, 125(43,0%) N 2 e 65(22,4%) N 3 , sendo o nível II (69,0%) o mais acometido, seguido do nível III -57 casos (13,5%), do I -49 casos (11,6%), do IV -25 casos (15,9%). Conclusões: O carcinoma espinocelular de base de língua é mais freqüente no homem branco da 5ª a 6ª década, tendo como fatores de risco o álcool e o fumo, sendo predominante o emprego do tabagismo nas mulheres. O tempo de queixa foi referido nos 6 meses iniciais, com predomínio dos estádios III e IV, sendo que os casos I e II eram todos etilistas e/ou tabagistas.
Summary Introduction: Leishmaniasis is classified into three clinical presentations: visceral, coetaneous and mucocutaneous. The latter is usually secondary to hematogenous spread after months or years of skin infection and can manifest as infiltrative lesions, ulcerated or vegetating in nose, pharynx, larynx and mouth, associated or not with ganglionics infarction. Laryngeal involvement is part of the differential diagnosis of lesions in this topography as nonspecific chronic laryngitis, granulomatosis and even tumors of the upper aerodigestive tract presenting atypical evolution. Sometimes it is difficult for the correct diagnosis of Leishmaniasis, with description of cases in the literature were conducted improperly. Objective: The objective of this study is to report a case of laryngeal Leishmaniasis addressing the difficulty of diagnosis, complications and treatment applied. Case Report: A patient with pain throat, dysphagia, odynophagia, dysphonia and weight loss, with no improvement with symptomatic medication. At telelaringoscopy, infiltrative lesion showed nodular supraglottis. He underwent a tracheotomy for airway obstruction and biopsy with immunohistochemical study for a definitive diagnosis of laryngeal Leishmaniasis. The patient was referred to the infectious diseases that initiated treatment with N-methylglucamine antimoniate with satisfactory response to therapy. Final Comments: Faced with a clinical suspicion of granulomatous diseases, it is essential to follow protocol laboratory evaluation associated with histological injury, to get a precise definition etiological without prolonging the time of diagnosis. Medical treatment for mucosal Leishmaniasis, recommended by the World Health Organization, was adequate in the case of laryngeal disorders, with complete resolution of symptoms.
