University of Texas M. D. Anderson Cancer Center cases filed as Hurthle cell and follicular carcinoma were reviewed. Requirements for including a case in the study were that the diagnosis of Hurthle cell or follicular carcinoma be confirmed, that histologic material and clinical information be adequate, and that there be at least 9 years of follow-up. The study group included 18 cases of Hurthle cell carcinoma and 33 cases of follicular carcinoma. Ten of the Hurthle cell carcinomas had extrathyroid invasion, three had intrathyroid invasion, and five were encapsulated (i.e., they had intracapsular invasion only). In the follicular carcinoma group, 5 tumors had extrathyroid invasion, 14 had intrathyroid invasion, and 14 were encapsulated. When the cases were stratified according to extent of invasion in this manner, there was no statistically significant difference in rate of local recurrence, rate of metastasis (either regional lymph node or distant), or patient survival between Hurthle cell carcinoma and follicular carcinoma. Other variables including patient age and sex, treatment differences, tumor size, vascular invasion, predominant growth pattern (follicular versus solid-trabecular), nuclear size and pleomorphism, mitotic rate, and tumor necrosis did not provide significant additional prognostic information. Metastases of both Hurthle cell and follicular carcinoma were mostly distant and predominantly involved bone and lung. Behavioral differences between Hurthle cell and follicular carcinoma that were not statistically significant included a higher rate of local recurrence in Hurthle cell carcinoma with intrathyroid invasion, more frequent occurrence of regional lymph node metastasis in Hurthle cell carcinoma with extrathyroid invasion, and absence of distant metastasis and death caused by tumor in encapsulated Hurthle cell carcinoma. Five follicular carcinomas and one Hurthle cell carcinoma appeared to have arisen within an adenoma.
