NCT01149161

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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)

Secondary Outcomes (1)

  • The efficacy of sentinel lymph node biopsy in micro PTC

    Until 5 year follow-up. (Dec. 2016)

Study Arms (2)

C group

ACTIVE COMPARATOR

Routine central neck dissection

Procedure: Routine central neck dissection

N group

NO INTERVENTION

No central neck node dissection

Interventions

Level VI neck node dissection during thyroid operation

C group
