Session: SAT 270-310-Thyroid Neoplasia (posters)
Poster Board SAT 272
Methods used: This retrospective study analyzed data from the VA Northern California Health Care System for patients enrolled between January 2010 and December 2014. Veterans were identified by ICD-9 codes for hyperthyroidism, and either thyroid nodules, thyroiditis, thyroid adenoma, or goiter. Veterans who underwent radioiodine or ultrasound thyroid scanning were identified . These records were subsequently reviewed manually for suspicious ultrasonographic findings (size, calcification, or geometry).
Summary of Results: 760 Veterans were identified by ICD-9 coding. Of these, 230 had thyroid ultrasounds, and 113 had radioiodine thyroid scans. There were 70 patients that had both ultrasound and radioiodine thyroid scans of which 84.3% were male and the average age was 62.9. Twenty-five had hyperthyroid nodules or areas on radioiodine studies and 31 had suspicious ultrasound scans (we excluded 7 individuals with “cold” thyroid scans). 18 had both and of these, 6 underwent fine needle aspirate (FNA) and 1 is planned for FNA.
Conclusions: While most Veterans identified as hyperthyroid did not undergo imaging studies, of those who did, a remarkable number had heretofore unexpected ultrasonographically-suspicious nodules. This preliminary observation suggests that ultrasound scans, a noninvasive and relatively inexpensive diagnostic modality, may have a role in the evaluation of the hyperthyroid patient in identifying those who might benefit from FNA.
