Sentinel Lymph Node Biopsy in the Thyroid Carcinoma; Randomized, Prospective Study
The investigators will assign all patients to three groups; no dissection group (Group I),
sentinel lymph node biopsy only group (Group II) and routine central neck dissection group
(Group III). At first, to know the necessity of routine central neck node dissection for
micro PTC,the investigators will compare the result of group I and group III. Additionally,
the investigators can analyze the usefulness of sentinel lymph node biopsy for substitution
of routine central neck node dissection for micro PTC.
Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Caregiver), Primary Purpose: Treatment
Is routine neck node dissection necessary in micro PTC?
To see the necessity of routine neck node dissection in micro PTC, we will compare the recurrence rate and other complication (e.g. hoarseness and hypocalcemia) between group I(no dissection) and group III(routine dissection) after completion of study(after 5 year f/u). To check the safety of this study, our result will be checked by korea institutional reveiw board every one year.
Until 5 year follow-up. (Dec. 2016)
