Which of the following is NOT a non-small-cell tumor of the lung?

a. Squamous cell carcinoma
b. Adenocarcinoma
c. Carcinoid tumor
d. Large-cell carcinoma

Correct Answer is C

Comment:

The term non-small-cell lung carcinoma (NSCLC) includes many tumor cell types, including large cell, squamous cell, and adenocarcinoma. Historically, these subtypes were considered to be a uniform group based on limited understanding of the distinct clinical behaviors of the subtypes as well as the fact that there were few treatment options available. With increasing understanding of the molecular biology underlying these tumor subtypes, however, the approach to diagnosis and management and the terminology used in describing these tumors is evolving rapidly.
