OBJECTIVE: To evaluate whether ultrasound-guided radiofrequency ablation (RFA) is reliable for unifocal T1aN0M0 papillary thyroid carcinoma in the isthmus (PTCI).
METHODS: 431 patients who underwent ultrasound-guided RFA for unifocal T1aN0M0 papillary thyroid carcinoma (PTC) were divided by location of the lesion into the PTCI group (52 females, 7 males, mean age 43.79 ± 12.04 years, range 22-74 years) and the PTCL group ((291 females, 81 males, mean age 43.42 ± 10.87 years, range 18-75 years) for comparative analysis. The efficacy of ultrasound-guided RFA was evaluated by volume reduction rate (VRR), complete disappearance rate (CDR) and disease progression, and the safety was evaluated by incidence of complications.
RESULTS: The two groups exhibited a consistent trend of change, with the PTCI group performing better in volume, VRR and CDR at all follow-up time points expect 1 month, but the differences were not statistically significant (p > 0.05). The mean initial volume of the PTCI group vs the PTCL group decreased significantly from 65.4 ± 69.79 vs 86.38 ± 87.09 mm³ (range 10.92-427.58 vs 3.05-471.6 mm³) to 0 vs 0 mm³ at a mean follow-up time of 31.12 ± 12.5 months (range 12-60 months); their VRR increased significantly from -618.62 ± 655.61% vs -789.85 ± 1135.07% at 1 month to 100% vs 100% at 48 months. No disease progression was found in the two groups. The PTCI group had no complications, whereas the PTCL group had a total of 7 complications (1.88%).
CONCLUSIONS: Ultrasound-guided RFA is reliable for unifocal T1aN0M0 PTCI. It can be promoted as an alternative to immediate surgery for selected PTC patients.
