Case Presentation:
69 Y/O female with an aggressive form of papillary thyroid cancer called Tall Cell Variant. She has had total thyroidectomy, and central compartment node removal.. 150 MCI was given after the first surgery. The first recurrence was in the right lateral neck. Another surgery was done. 200 Millicuries of I/131 was given. Over 12 months her
thyroglobulin,TG rose from 0.36 to 6.5 with suppressed TSH. The last Whole body scan was negative. The ultrasound lymph node mapping revealed central compartment abnormal nodes. The USGFNA biopsy was positive for recurrence, and the TG Cancer marker was 35,000 in the needle washing from the largest node. Because of the aggressive nature of the cancer a PET/CT was done to make sure there was distant spread to the lungs or bones. The scan was positive only for the nodes seen on ultrasound in the central compartment. The patient had suffered a right vocal cord injury at the first surgery, and therefore re-entry in the central compartment was more risky. The thyroid surgeon agreed to go in only if I could localize the nodes for him before the surgery. One hour before she went to the hospital, she came to the thyroid center, and under US guidance I placed a drop of dye on the anterior surface of the largest node. The surgery was uneventful. There was no changes in her voice or the blood calcium post surgery. However when she returned for the 4 week post surgery visit her cancer marker was markedly decreased from 6.5 to just above the lower limit of <0.15, at 0.23. There were 3 positive nodes clustered around the blue dye marked node. The surgeon had no problem finding the PET positive nodes with my dye marker.

Good Luck,

The Thyroid Doctor's log after seeing his patients. I am a rare bird. I am one of the few physicians to practice clinical thyroidology only for 35 years. I am the sole physician at the Santa Monica Thyroid Center, and have the best thyroid blood lab with Dr.Carole Spencer, expert in thyroid hormone analysis, and thyroid cancer markers, as my lab director.The lab is also CLIA certified in thyroid cytology. Dr.Guttler is a thyroid ultrasonographer certified by AACE, and AIUM.
