ABSTRACT
Abstract

Introduction:

For papillary thyroid microcarcinoma patients, the reported incidence of lymph node metastasis is as high as 40%, and these occur mainly in the central compartment of the neck. Because these metastases are difficult to detect using ultrasonography preoperatively, some authors advocate routine central neck dissection in papillary thyroid microcarcinoma patients at the time of initial thyroidectomy.

Objective:

To evaluate whether prophylactic central neck dissection can decrease the local recurrence rate of papillary thyroid microcarcinoma after thyroidectomy.

Methods:

The publicly available literature published from January 1990 to December 2017 concerning thyroidectomy plus prophylactic central neck dissection versus thyroidectomy for papillary thyroid microcarcinoma was retrieved by searching the national and international online databases. A meta-analysis was performed after the data extraction process.

Results:

Four studies were finally included with a total of 727 patients, of whom, 366 cases underwent thyroidectomy plus prophylactic central neck dissection and 361 cases received thyroidectomy only. As shown by the meta-analysis results, the recurrence rates in cases of thyroidectomy plus prophylactic central neck dissection were approximately 1.91% and were significantly lower than those with thyroidectomy only (OR = 0.24, 95% CI [0.10, 0.56], p = 0.0009).

Conclusion:

For patients with papillary thyroid microcarcinoma, thyroidectomy plus prophylactic central neck dissection is a safe and efficient procedure and it results in lower recurrence rate. Since the evidences are of low quality (non-randomized studies), further randomized trials are needed.
RESUMO
Resumo

Introdução:

A incidência relatada de metástases linfonodais chega a 40% em pacientes com microcarcinoma papilífero de tireoide e essas ocorrem principalmente no compartimento cervical central. Como essas metástases são difíceis de ser detectadas com o uso de ultrassonografia no pré-operatório, alguns autores defendem o esvaziamento cervical central de rotina em pacientes portadores de microcarcinoma papilífero de tireoide no momento da tireoidectomia inicial.

Objetivo:

Avaliar se o esvaziamento cervical central profilático pode diminuir a taxa de recorrência local de microcarcinoma papilífero de tireoide após a tireoidectomia.

Método:

A literatura disponível, publicada de janeiro de 1990 a dezembro de 2017, sobre tireoidectomia com esvaziamento cervical central profilático versus tireoidectomia somente para microcarcinoma papilífero de tireoide foi obtida através de busca nas bases de dados online nacionais e internacionais. A metanálise foi feita após o processo de extração de dados.

Resultados:

Quatro estudos foram finalmente incluídos na metanálise, com 727 pacientes, dos quais 366 foram submetidos à tireoidectomia com esvaziamento cervical central profilático e 361 só receberam tireoidectomia. Como mostrado pelos resultados da metanálise, as taxas de recorrência com tireoidectomia com esvaziamento cervical central profilático foram de 1,91% e foram significantemente menores do que aquelas em pacientes submetidos somente à tiroidectomia (OR = 0,24, IC95% [0,10-0,56], p = 0,0009).

Conclusão:

Para pacientes com microcarcinoma papilífero de tireoide, o esvaziamento cervical central profilático é um procedimento seguro e eficiente e resulta em menor taxa de recorrência. Como as evidências são de baixa qualidade (estudos não randomizados), mais estudos randomizados são necessários.
