Primäre Trachealtumoren in Hals und Mediastinum

Abstract

Primary tumors of the trachea account for less than 0.1% of all tumors. They are malignant in more than 90% of cases with squamous cell carcinoma and adenoidcystic carcinoma accounting for 2/3 of all tracheal tumors. Since they are often misdiagnosed as asthma or chronic lung disease, diagnosis can be delayed for years. Once the diagnosis has been established, surgical resection being the only curative treatment should be considered first. Modern techniques for tracheal surgery such as laryngotracheal, tracheal or carinal resection and different tracheal mobilisation maneuvers such as laryngeal and hilar release allow for resection of more than 50% of the trachea and anastomosis without excessive tension. Results in patients with complete tumor resection are good with 5-year and 10-year survival between 39% and 79% and between 18% and 51%, respectively. However, careful patient evaluation, preservation of tracheal blood supply and accepting the limits of resectability are mandatory to avoid major complications that accompany tracheal resections in more than 20% of cases depending on the type of resection.

Tracheal lobular capillary hemangioma treated with laser photocoagulation

“…( 1 ) These tumors are approximately 180 times less common than are lung tumors, ( 2 ) accounting for 0.1-0.3% of all tumors. ( 2 , 3 ) Their diagnosis is usually delayed, because the symptoms are initially misinterpreted or patients are misdiagnosed as having asthma.…”

( 2 , 3 ) Seu diagnóstico é geralmente tardio, ou porque os sintomas são inicialmente mal interpretados ou porque os pacientes recebem o diagnóstico equivocado de asma.…”

Tracheal Lymphoma Presenting with Acute and Progressive Dyspnea

“…Tracheal neoplasms account for less than 0.1% of all malignancies (8). In spite of their low incidence, these tumors represent a potentially lethal phenomenon.…”
