Cirugía transoral en cáncer de laringe estadificado T1-T2 / Transoral surgery in T1-T2 staged laryngeal cancer

Se realizó un estudio prospectivo y descriptivo, incluyendo 103 pacientes que fueron tratados por cáncer de laringe en etapa inicial (T1-T2) con cirugía transoral. De ellos, 55 se diagnosticaron en estadio T1, 16 en estadio T1-b y 32 en estadio T2. El control local inicial (CLI) en pacientes con tumores malignos de laringe estadificados T1 fue 91%, el control local con rescate (CLR) 96%, la preservación de la función de la laringe (PFL) 93% y la sobrevida específica 96%. En T1-b, el CLI fue 81%, el CLR 94%, la PFL 94% y la sobrevida específica 94%. En T2, el CLI fue 63%, el CLR 94%, la PFL 72% y la sobrevida específica 78%. La cirugía transoral en cáncer de laringe con T inicial tiene resultados oncológicos similares a otros tratamientos (cirugía externa o radioterapia), pero consideramos que es la mejor opción por su baja morbilidad, menor duración del tratamiento, y porque deja abiertas todas las posibilidades para tratar posibles recurrencias.

A prospective and descriptive study was conducted, including 103 patients who were treated for early stage laryngeal cancer (T1-T2) with transoral surgery. Of these, 55 were diagnosed in stage T1, 16 in stage T1-b and 32 in stage T2. The initial local control (CLI) in patients with malignant T1 laryngeal tumors was: 91%, local control with rescue (CLR) 96%, preservation of larynx function (PFL) 93% and specific survival 96%. In T1-b the CLI was 81%, the CLR 94%, the PFL 94% and the specific survival 94%. In T2 the CLI was 63%, the CLR 94%, the PFL 72% and the specific survival 78%. Transoral surgery in laryngeal cancer with initial T has oncological results similar to other treatments (external surgery or radiotherapy), but we consider that it is the best option because of its low morbidity, shorter duration of treatment, and because it leaves open all the possibilities to treat possible recurrences.

Obstructing mass lesion of epiglottis: it can be tubercular.

We report a case of 60-year old male who had difficulty in breathing as well as in swallowing. On examination, he was found to be having proliferative growth of epiglottis and right aryepiglottic fold mimicking neoplasm. So emergency tracheostomy was performed and biopsy taken. He was found to be having asymptomatic miliary mottling on routine x-ray chest PA view. Further on HRCT, it turned out to be lesion suggesting tubercular etiology. Histopathology (epiglottic biopsy) report confirmed the whole process as tubercular. The patient recovered promptly in due course with anti-tubercular treatment. Point remains to be seen that if we can avoid tracheostomy and its complications in such cases.

Importância da invasão do espaço pré-epiglótico no planejamento terapêutico do câncer da laringe e faringe / The importance of pre-epiglottis space invasion in the treatment planning of larynx and hypopharynx cancer

O comprometimento do espaço pré-epiglótico pode alterar a indicação de cirurgias parciais da laringe. OBJETIVO: Avaliar a concordância inter e intra-observadores da análise da tomografia computadorizada do envolvimento do espaço pré-epiglótico (EPE) por carcinoma epidermóide do trato aerodigestivo superior e sua repercussão no planejamento terapêutico. MATERIAL DE MÉTODO: Foram analisadas retrospectivamente as tomografias computadorizadas, do período de 1990 a 2004, de 95 pacientes com carcinoma epidermóide, sendo 87 do sexo masculino e apenas 8 eram do sexo feminino, com idade variando de 32 a 73 anos. Os exames foram avaliados duas vezes por três radiologistas, separadamente, sem o conhecimento prévio do estadiamento clínico. Todos os pacientes não haviam recebido qualquer tratamento até o momento do exame de imagem, como cirurgia, quimioterapia ou radioterapia. Todos os casos tiveram o diagnóstico confirmado por biópsia. As informações foram obtidas baseadas na revisão de prontuários médicos. RESULTADOS: O índice Kappa foi calculado para estimar a concordância entre os três observadores. A força de concordância variou de boa a excelente. CONCLUSÃO: Após um Kappa geral de 0,72, o resultado sugere uma concordância geral boa na avaliação do envolvimento do espaço EPE através de tomografia computadorizada.

The involvement of pre-epiglottis space can change the indication for partial laryngeal resection. AIM: The aim of this study was to evaluate inter-observer and intra-observer agreement by means of computed tomography analysis regarding the involvement of the pre-epiglottis space (PES) from carcinoma of the upper aerodigestive tract and its relation with therapeutic planning. MATERIALS AND METHODS: Retrospective study of ninety-five computed tomography exams of patients with squamous cell carcinoma, from 1990 to 2004, were selected and evaluated; 87 were males and eight females, with ages ranging from 32 to 73 years. Imaging results were analyzed twice by three radiologists, individually, without any previous knowledge of the clinical stage. No patient had received any previous treatment up to the moment of imaging examination, such as surgery, chemotherapy or radiotherapy. All the cases were confirmed by biopsy. Information was obtained from the medical charts. RESULTS: Kappa Index was calculated by assessing agreement between the three observers. We obtained substantial to almost perfect levels of agreement. CONCLUSIONS: After a general Kappa Index of 0.72, the results suggest a substantial agreement in the involvement of the PES by means of computed tomography analysis.

Ductal piglottic cyst

A 28 years old female presented with a feeling of something sticking in her throat. Indirect laryngoscopy revealed a cystic mass lying on the left pyriform fossa. Direct laryngoscopy revealed a benign looking mass arising from the epiglottis and following excision histopathology revealed a ductal cyst of the epiglottis. A brief review of the literature accompanies the case report
