title: Thyroid cancer in patients 70 years of age or older. Retrospective study of 50 patients.
abstract: This report presents our experience with 50 thyroid cancer patients 70 years of age or older, out of 606 patients of all ages. Comparing this series to those describing thyroid cancer patients of all ages, we found that thyroid carcinoma in the 70+ age group presents at a more advanced clinical stage, behaves more aggressively, and has a higher death rate. These findings are attributed mainly to the higher incidence of undifferentiated carcinoma and the more aggressive course of the differentiated types of carcinoma in the older age group. If suspected thyroid nodules are managed by initial radical treatment, carcinoma can be diagnosed earlier and patients will survive longer.
