What is the most common type of cancer in the trachea?
I - CEC (44%) and adenoid cystic carcinoma (16%) are the most common types of cancer in the trachea.
II - The trachea can be a site of metastasis: thyroid, esophagus, larynx, and lung.
III - CEC is a more aggressive lesion, with ulcerated, vegetative appearance, and more obstructive symptoms.
IV - Adenoid cystic carcinoma is less aggressive, tends to displace structures and not invade them, and has no preference for sex and no relation to smoking.
a) I and II are correct.
b) III and IV are correct.
c) I, II, and III are correct.
d) I, II, III, and IV are correct.

A resposta correta é a alternativa "a) I and II are correct." (a) I e II estão corretas). A partir da informação apresentada, é possível concluir que o CEC (carcinoma epidermoide) e o adenocarcinoma são os tipos mais comuns de câncer na traqueia, representando 44% e 16% dos casos, respectivamente. Além disso, a traqueia pode ser um local de metástase de outros tipos de câncer, como tireoide, esôfago, laringe e pulmão. As informações III e IV não estão corretas, pois o CEC é uma lesão menos agressiva e o adenocarcinoma tende a invadir estruturas em vez de deslocá-las.
