Abstract
AN ESTIMATED 16100 cases of thyroid cancer will be diagnosed in 1997,1 and the overwhelming majority of these will be well-differentiated malignant neoplasms. The virulence of papillary and follicular carcinoma is low, with overall mortality rates ranging from 1.2%2 to 17%.3 No differences in survival have been seen, to our knowledge, between follicular and papillary cancers.4,5 These low death rates are attributed primarily to the biological characteristics of the disease and perhaps to the success of surgery and radioactive iodine therapy.
