OBJECTIVE: Primary @entity5 are rare, occurring in 0.2 per 100,000 @entity1 per year. @entity2347 ( @entity2347 ) is the second most common histologic type of @entity5 . Its clinical behavior is different from the other @entity31278 and thus should be studied separately. STUDY DESIGN/METHODS: Retrospective review of the medical records of six @entity1 with tracheal @entity2347 who were treated at University Hospitals of Cleveland between 1971 and 1996 and literature review. RESULTS/CONCLUSION: Tracheal @entity2347 is an indolent @entity5 that affects @entity1 at any age but has a peak incidence in the fifth decade. There is a nearly equal male-to-female ratio. Almost half of tracheal ACCs occur in the proximal @entity825 , accounting for the most common presenting symptoms: @entity1353 , cough, and hoarseness. Because of the hoarseness, @entity1 are often referred to an otolaryngologist. Complete resection provides the best chance for increased survival. Neutron beam radiotherapy holds promise for adjuvant therapy.
