Background. Ultrasound-guided percutaneous ethanol ablation (UPEA) of neck nodal metastases (NNM) has rarely been reported in papillary thyroid carcinoma (PTC) patients with advanced localized disease. Methods. We ablated 25 PTC patients with stage III or IVA disease (mean age 58 years) who had recurrent NNM after surgery and I-131 therapy. Diagnosis of 37 selected NNM was proven by ultrasound-guided biopsy. UPEA was usually performed in 2 outpatient sessions. Results. After UPEA, 35 of 37 NNM (95%) decreased in size. None had significant Doppler flow. Seventeen (46%) disappeared on rescanning. Serum thyroglobulin fell in 19 of 22 (86%) without thyroglobulin autoantibodies. None of the UREA-treated NNM, followed on average for 5.4 years, required further intervention. Six patients (24%) subsequently developed 18 new recurrences. Of the 18, 15 (83%) were managed successfully by UPEA rather than operation. None of the 25 patients developed permanent hoarseness or have died from PTC. At our institution, where patients undergoing nodal dissections are charged $35-45,000, each outpatient UPEA procedure saves health providers approximately $38,400. Our 25 ablated patients, by avoiding 40 further neck reexplorations, on average, saved $61,440 in charges. Conclusion. UPEA for NNM in advanced localized PTC has proved safe and effective. It is also considerably less expensive than the conventional operative alternative of nodal dissection.
