Topic: SURGERY FOR THYROID CANCER Title: Radio-guided surgery for non-I-avid thyroid cancer

Outcome: Twenty-three women and 14 men were followed after RGS for 35.4 + 12.5 months (range 9-57). There were 33 papillary (one “tall” cell variant), 2 follicular, and 2 Hürthle cell cancers. In 7 patients, thyroid cancer recurred in the neck while cervical lymph node metastases were found in 31 patients (one patient had papillary cancer both in the thyroid bed and cervical lymph nodes). Sixty-six discrete nodules ranging from 6 to 45 mm (mean tumor diameter: 18.4 + 8.5 mm) were identified by both high-resolution ultrasound and Tc-sestamibi probe guided RGS. After RGS, Tg (thyroglobulin) fell in 33 of 37 patients and mean target/non target sestamibi uptake ratios decreased in all 37 patients (P < 0.0001).
