Extent of Central Lymph Node Dissection in Papillary Thyroid Microcarcinoma

April 20, 2016 updated by: Jee soo Kim, Samsung Medical Center

Sentinel Lymph Node Biopsy in the Thyroid Carcinoma; Randomized, Prospective Study

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.

Study Overview

Status

Unknown

Conditions

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Is routine neck node dissection necessary in micro PTC?
Time Frame: Until 5 year follow-up. (Dec. 2016)

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 Outcome Measures

Time Frame

Time Frame: Until 5 year follow-up. (Dec. 2016)
Until 5 year follow-up. (Dec. 2016)
