Three-hundred-and-fifty patients with carcinoma of the thyroid have been accumulated from the Evanston, Grant, and Augustana Hospitals. We have eliminated sarcomatous lesions to avoid confusion. The series from each hospital was evaluated separately, but after study it was seen that there was no contrast between the groups. Therefore, they were considered as a whole. When carcinoma of the thyroid is discussed or the results of its treatment evaluated, they must be projected against some type of classification.
In this article histological classification has been used, dividing the tumors into 2 main groups—the adenocarcinomas and the undifferentiated carcinomas. The adenocarcinomas are further divided into 5 separate groups—the in situ lesions, embryonal lesions, pure papillary lesions, mixed papillary, and follicular lesions. This roughly gives us the division into those tumors that are gland-like and those that are completely atypical.
The in situ lesions include a group of patients in whom the tumor
