Retrospective analysis of patients with differentiated thyroid carcinoma.

ABSTRACT

The data of well-differentiated thyroid carcinoma in 677 patients who have been followed up from 1979 to 1998 were analyzed at Nuclear Medicine Section, Siriraj Hospital. The results revealed that the sex ratio of female male was 2.961, and the age ranged between 9 and 96 years with the mean + SD of 45.8 + 16.6 years. The peak incidence of female patients occurred chiefly in the middle age (31-40 years), while the majority of male patients occurred predominantly in late middle age and in the elderly (51-61 years). The patients with papillary, follicular and mixed papillary-follicular carcinomas were 49.0%, 40.0% and 11.0%, respectively. These data also indicated that 8.0% of thyroglobulin antibodies and 5.3% of microsomal antibodies by haemagglutination method were detected in the sera of these patients. Moreover, the follow-up times of the patients with treated differentiated thyroid carcinomas at 1-11 months, 1-5 years, 6-10 years, 11-15 years and over 16 years were found to be 13.1%, 62.3%, 14.8%, 7.0% and 2.8%, respectively.
