ABSTRACT

BACKGROUND: Hemangiopericytomas (HPCs) are rare tumors derived from mesenchymal cells with pericyte differentiation. About 5% of head and neck HPCs occur in the nasal cavity and paranasal sinuses. Due to its rarity, rich vascularity and variable biological behavior, its management is a challenge in itself. CASE: We report a case of sinonasal HPC in a Jehovah's Witness patient and discuss the obstacles and care related to the restrictions and therapeutic challenges involved in the approach to the patient. The patient was successfully treated by endoscopic endonasal approach with all per-operative care and restrictions being respected and attended. CONCLUSIONS: The management of HPC by itself involves challenges and when associated with other restrictive conditions attention and care are required.

ABSTRACT

OBJECTIVE: To evaluate the utility of computerized manometry (CM) to identify pharyngoesophageal segment (PES) spasm during tracheoesophageal speech. STUDY DESIGN: Prospective clinical, controlled study. SUBJECTS AND METHODS: Intraluminal pressures of the PES were collected in 12 tracheoesophageal speakers without spasm and 8 tracheoesophageal speakers with PES spasm before and after localized injection of botulinum toxin to the PES. All subjects underwent voice analysis and videofluoroscopy in addition to CM before and after treatment. RESULTS: All tracheoesophageal speakers with PES spasm presented with mean intraluminal pressures greater than 16 mmHg (mean, 25.36 mmHg). In contrast, mean intraluminal pressures of subjects without spasm was 11.76 mmHg (P<0.05). The negative predictive value associated with the use of 16 mmHg as a threshold value for spasm was 100%. CONCLUSION: CM is a clinically useful tool to aid in speech rehabilitation for tracheoesophageal speakers. Intraluminal pressures of greater than 16 mmHg was highly predictive for PES spasm.

ABSTRACT

CONCLUSION: In patients with early glottic squamous cell carcinoma (SCC) submitted to CO2 laser endoscopic resection, local disease recurrence was significantly correlated with the presence of positive additional surgical margins on permanent sections. OBJECTIVES: To evaluate the rate of cancer recurrence in patients with early glottic SCC submitted to CO2 laser endoscopic resection according to margin status after resection, stage of disease and postoperative radiotherapy. The rate of larynx preservation and the length of hospital stay were also evaluated. MATERIAL AND METHODS: Forty consecutive patients with early glottic cancer were subjected to laser endoscopic resection surgery of glottic cancer followed by frozen-section control of margins, with intraoperative enlargement of margins when positive. Adjuvant radiation therapy or enlargement of previous margins was indicated in the case of positive additional surgical margins on permanent section. RESULTS: Local recurrence occurred in three patients (7.5%), all with positive additional surgical margins on permanent section. Positive additional surgical margins on permanent section were related to 37.5% of recurrences and negative additional surgical margins with 0% of recurrences (p=0.006). All patients spent at most 1 day at the hospital.

ABSTRACT

Avaliar o uso em longo prazo de próteses fonatórias (PF) para reabilitação fonatória de pacientes submetidos à laringectomia total (LT). Foram estudados a influência do tempo de realização da punção tráqueo-esofágica (PTE), o uso de radioterapia pós-operatória (RTXpos-op), idade e seguimento do paciente, sobre a taxa de sucesso de uso da PF. FORMA DE ESTUDO: Clínico prospectivo. MATERIAL E MÉTODOS: Setenta e um pacientes submetidos à LT e reabilitados com PF de longa permanência. Todos foram avaliados por otorrinolaringologista e fonoaudióloga, quanto aos aspectos funcionais vocais, durante o seguimento. Os dados relativos a tempo de colocação da PF, tempo de utilização da PF, uso de RTXpos-op, idade do paciente, tempo de seguimento e tempo de duração de cada PF foram anotados. RESULTADOS: Houve 87 por cento de pacientes com PTE primária e 13 por cento com secundária. O tempo de seguimento variou de 12 a 87 meses, com média de 38 meses para a PTE primária e 51 meses para a secundária. Houve 59 por cento de pacientes submetidos a RTXpos-op. A taxa de sucesso geral foi de 94 por cento. Na PTE primária foi de 97 por cento e na secundária 78 por cento (p=0,07) e, após dois anos, foi de 96 por cento na PTE primária e 75 por cento na secundária (p=0,07). Utilização de RTXpos-op e idade do paciente não influenciaram no sucesso de utilização de PF, independentemente do tempo de seguimento. CONCLUSÕES: Houve tendência de maior sucesso na reabilitação vocal de pacientes submetidos à LT com a PTE primária. O uso de RTXpos-op e idade não influenciou nesta taxa de sucesso.

ABSTRACT

OBJECTIVE: To evaluate the long-term use of indwelling Blom-Singer voice prosthesis (VP) for vocal rehabilitation of patients submitted to total laryngectomy (TL). The influence of the timing (primary or secondary) of tracheoesophageal puncture (TEP), use of radiotherapy (xRT), patient age, and length of follow-up were studied to evaluate the success rate of VP use. STUDY DESIGN AND SETTING: Prospective clinical study in a tertiary referral center. Seventy-one patients were submitted to TL and rehabilitated with indwelling VP. All patients were evaluated for vocal functional issues by an otolaryngologist and a speech pathologist at 1 month, then at every 3 months up to 1 year, and then at every 6 months after 1 year of follow-up. The relative data on time of placement of VP, time of VP use, xRT, age, length of follow-up, and life span of each VP were recorded during the follow-up. RESULTS: Eighty-seven percent of the patients underwent primary and 13%, secondary TEP. The follow-up varied from 12 to 87 months, with an average of 38 months for primary and 51 months for secondary TEP. Fifty-nine percent of the patients were submitted to xRT. The general rate of success was 94%, with 97% for primary and 78% (P = 0.07) for secondary TEP; after 2 years, the success rate was 96% for primary and 75% for secondary (P = 0.07) TEP. The use of xRT and patient age had no influence on the success of VP use for primary and secondary TEP, independently of the length of follow-up. CONCLUSIONS: The success rate of voice rehabilitation with VP was 94%. In primary TEP, the success rate was 97%, whereas in secondary TEP it was 78%; 2 years later, it was 96% and 75%, respectively. A tendency for a higher success rate in voice rehabilitation after TL was observed in primary TEP. The use of xRT and age of patient had no influence on the success rate.

ABSTRACT

UNLABELLED: To evaluate long-term use of indwelling Blom-Singer voice prosthesis (VP) for vocal rehabilitation of patients submitted to total laryngectomy (TL). We studied the influence of time of performance of tracheo-esophageal puncture (TEP), use of radiotherapy (XRT), patients' age and length of follow-up, on the rate of success of use of VP. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: Seventy-one patients were submitted to TL and rehabilitated with indwelling VP. Both otolaryngologist and speech pathologist evaluated all patients for the vocal functional issues during the follow-up. The relative data on time of placement of VP, time of use of PF, use of XRT, age, length of follow-up and interval of duration of each VP were recorded during the follow-up. RESULTS: There was 87% of patients with primary TEP and 13% with secondary. The follow-up varied from 12 to 87 months, with average of 38 months for primary and 51 months for secondary TEP. There were 59% of patients submitted to XRT. The general rate of success was of 94%. In primary TEP it was of 97% and in the secondary, it was 78% (p=0.07) and after two years, the success rate was of 96% in primary TEP and 75% in secondary TEP (p=0.07). The use of XRT and patient age did not influence the success of use of VP among primary and secondary TEP, independently of length of follow-up. CONCLUSION: Tendency to greater success rate in voice rehabilitation after TL with primary TEP was observed. Postoperative XRT and age did not influence success rate.

ABSTRACT

Introduçäo: A traqueotomia está indicada em condiçöes com obstruçäo respiratória alta ou doença pulmonar obstrutiva crônica. As válvulas fonatórias (VF) de traqueotomia já foram anteriormente descritas, porém apresentam alto custo para o paciente, pois säo todas importadas. Objetivo: Demonstrar a VF, desenvolvida na Universidade Estadual de Campinas, confeccionada em aço inox, para cânula de traqueotomia e a possibilidade de sua utilizaçäo na reabilitaçäo fonatória desses pacientes. Forma de estudo: Clínico prospectivo. Material e Método: A VF, desenvolvida na Universidade Estadual de Campinas, foi utilizada em dez pacientes consecutivos. A válvula tem diafragma dentro de um corpo em aço inox com encaixes de plástico. Ela permite o direcionamento do ar para a laringe durante a fonaçäo com oclusäo do traqueotoma e abertura do mesmo na inspiraçäo, sob baixa pressäo. Resultados: Atualmente dez pacientes estäo utilizando estas VF com fonaçäo sem necessidade de oclusäo do orifício externo da cânula e confortavelmente, inclusive durante o sono. Discussäo: As VF para cânulas de traqueotomia melhoram a comunicaçäo, inteligibilidade, higienizaçäo e umidificaçäo das vias aéreas dos pacientes traqueotomizados. Há também melhora no aspecto emocional e diminuiçäo das secreçöes orais e traqueais. O custo de produçäo dessa VF nacional é baixo e milhares de pacientes poderäo ser beneficiados no Brasil. As crianças com traqueotomia podem apresentar retardo no desenvolvimento da linguagem. O uso da VF facilitará a comunicaçäo e a interaçäo social dessas crianças. Conclusäo: A válvula fonatória metálica, desenvolvida na Universidade Estadual de Campinas, acoplada a uma cânula de traqueotomia metálica permite fonaçäo, sem a oclusäo digital da cânula, e respiraçäo sob conforto

ABSTRACT

O grupo de carcinoma espinocelulares da cabeça e pescoço em pacientes com alto risco de desenvolver metástases à distância, tem sido bem definidos do ponto de vista prognóstico em nossaa instituiçäo. Com intuito de selecionar fatores de risco preditivos no desenvolvimento de metástases à distância, Leemans e col analisaram um grupo de 281 pacientes com carcinoma epidermóide que näo desenvolveram doença recorrente acima da clavículas (79). Todos os pacientes foram primariamente operados e submetidos à radioterapia complementar diante de 3 ou mais linfonodos histológicos metastáticos na avaliaçäo da peça operatória, sendo que neste grupo, a incidência de metástases à distânacia a 5 anos foi de 10,7 por cento. O número de metástases em linfonodos em n§ de 3 ou mais, foi determinante do desenvolvimento de metástases à distância em 50 por cento dos casos, fato este näo detectado quando esta cifra estava abaixo de 3 linfonodopatias. Em contrapartida, a presença de ruptura extra-capsular foi um fator dramático de mudança de prognóstico no que diz respeito à presença de metástases à distância (3 vezes mais que nos casos onde a ruptura extra-capsular estava ausente). Outro aspecto que mereceu a atençäo dos autores, foi aquele relacioando com os pacientes recidivados loco-regionalmente ocorrendo nestes pacientes duas vezes mais metástases sistêmicas (80,81). A opçäo proposta no sentido de introduzir uma terapia adjuvante para os pacientes com alto risco de desenvolver metástases à distância, é o emprego de anticorpos monoclonais marcados. Recentemente, apresentamos um primeiro estudo experimental em carcinoma epidermóide da cabeça e pescoço tratados por radio-imunoterapia. Foi demonstrado que a IgG E48 de anticorpos monoclonais marcados com I131 foi capaz de eliminar implantes humanos de carcinoma escamocelular em tumores transplantados para ratos (82). Em 20 por cento dos experimentos desenvolvidos (2 em 10 tumores), foi observada uma regressäo em ratos tratados com 400µCi de IgG E48 de anticorpos monoclonais marcados com iodo 131 com 800 µC , 2 em 7 tumores (29 por cento) mostraram completa remissäo sem recidiva durante o seguimento (> 3 meses). Nos mesmos casos, a utilizaçäo de quimioterapia com doxorubicina, 5 fluor-uracil, cisplatinum e methotrexate exibiram uma resposta menor, demonstrando um efeito antitumoral mais fugaz, näo ocorrendo nenhuma cura com o emprego da antiblásticos. Estes dados sugerem que o emprego da radio-imunoterapia no tratamento do câncer da cabeça e pescoço pode se transformar numa nova alternativa no tratamento das lesöes com altas capacidade de recidiva e disseminaçäo
