    Risk-group stratification based on prognostic factors is well established in differentiated carcinoma of the thyroid gland.

    Patients in the low-risk group have an excellent prognosis, whereas there is significant mortality associated with the high-risk group.

    The purpose of this paper is to analyze the patterns of treatment failure in the various (local, regional, distant, and associated mortality) risk groups.


    In a retrospective review of a consecutive series of 1038 previously untreated patients with differentiated carcinoma of the thyroid during a period of 55 years, various prognostic factors and risk groups were analyzed.

    Significant prognostic factors were patient's age, presence of distant metastasis, extrathy-roid extension, size, and grade of the tumor.

    Based on these factors, patients were divided into low- (39%), intermediate (39%), and high- (22%) risk groups.


    The overall treatment-failure rates in the low-intermediate-and high-risk groups were 13%, 26%, and 50%, respectively, whereas the mortality rates in the same groups were 1%, 10%, and 33%, respectively.


    The overall incidence of recurrence rate in the low-risk group is only 13%, compared with 50% in the high-risk group.

    The incidence of distant metastasis in the low-risk group is only 2%, compared with 34% in the high-risk group. (...)
