Abstract

Background and Objective: Factors that are associated with the recurrence after radioactive iodine ablation therapy have not been identified yet. The aim of this study is to elucidate the factors that are related to the recurrence after thyroid surgery of the thyroid papillary cancer followed by radioactive iodine ablation therapy.
Patients and Methods: Fifty four cases who had underwent thyroid cancer surgery and postoperative radioactive iodine ablation therapy were included in this study. Mean followup duration was 7 years. There were 41 women and 13 men. Data analysis was done retrospectively with medical record review. Chi-square test and Fisher’’s exact test was used for the statistical analysis.
Results: Age over 40, capsular invasion, and loca invasion were the factors that were associated with the high rate of recurrence. But sex, size of the tumor, multiplicity and extent of the surgery were not related to the recurrence.
Conclusion: Without the curative resection of the tumor, radioactive iodine ablation therapy cannot lower the recurrence rate. So aggressive resection of the thyroid papillary cancer is important.The more data accumulated and the longer the followup, the easier we can reveal the recurrence-related factors of postoperative radioactive ablation therapy.
