  Purpose

Occult lymph node metastasis is common in micro papillary thyroid cancer. However, the role of lymph node dissection in the treatment of microPTC remains controversial. The investigators want to investigate the usefulness routine central dissection and sentinel lymph node biopsy in prognosis of micro PTC. This is a prospective randomized control study. The investigators started this study from May of 2009 and this study will be continued until Dec. 2011.

Primary Outcome Measures:
  • Is routine neck node dissection necessary in micro PTC? [ Time Frame: Until 5 year follow-up. (Dec. 2016) ] [ Designated as safety issue: Yes ]

    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.



Secondary Outcome Measures:
  • The efficacy of sentinel lymph node biopsy in micro PTC [ Time Frame: Until 5 year follow-up. (Dec. 2016) ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 801
Study Start Date: May 2009
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: No central neck dissection
No central neck intervention, Patient's Number of this group: 267
Active Comparator: Routine central neck node dissection Procedure: Routine central neck dissection
Level VI neck node dissection during thyroid operation for micro PTC. Patient's Number of this group: 267
Active Comparator: Sentinel lymph node biopsy for central neck Procedure: Sentinel lymph node biopsy for central neck
Sentinel lymph node biopsy with methylen blue. Peritumoral injection in operating room, Patient's Number of this group: 267

Detailed Description:

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.
