Introdução: O carcinoma adenoide cístico representa o segundo tipo histológico mais frequente entre os raros tumores traqueais. Relato do caso: Paciente de 67 anos com dispneia progressiva. Tomografia de tórax mostrou formação expansiva no terço distal da traqueia cuja biópsia evidenciou carcinoma adenoide cístico primário de traqueia. O paciente evoluiu com piora do quadro respiratório, sendo encaminhado em caráter de urgência para radioterapia concomitante à quimioterapia com cisplatina, apresentando então melhora respiratória importante. Dois anos e dez meses após o término do tratamento, apresentava-se sem queixas clínicas relevantes e sem toxicidades crônicas inerentes ao tratamento. Broncoscopia e tomografia de tórax não mostravam sinais de recidiva tumoral. Conclusão: O carcinoma adenoide cístico de traqueia tem na cirurgia sua principal modalidade terapêutica. Contudo, em pacientes com tumores irressecáveis, a radioterapia representa a principal modalidade terapêutica, podendo ser combinada à quimioterapia. O prognóstico desses tumores permanece reservado, mesmo após ressecção completa, com altas taxas de recidiva local e/ou a distância.
Introduction: Head and neck squamous cell carcinoma (HNSCC) encompass a heterogeneous group of tumors with a challenge treatment. In Brazil, HNSCC represent the third most frequent neoplasia in men. Aim: The aim of this study was to review the most relevant and practice changing articles recently published. Material and methods: The review of the literature covered studies published over the last year and described key evidence-based changes in treatment of HNSCC. Results: We retrieved nine studies with clinical impact. The main updates include: 1) systematic review in the treatment delivery time; 2) recommendations for the diagnosis of HPV oropharyngeal carcinoma; 3) guidelines for the delineation of target volumes in radiation therapy; 4) de-intensification of treatment in HPV positive oropharyngeal carcinoma; 5) induction chemotherapy; 6) immunotherapy. Conclusions: The treatment and diagnosis of HNSCC has changed over the last year, mainly with the inclusion of HPV positive oropharyngeal carcinoma and immunotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
