Abstract

Objective

The survival benefit of prophylactic lateral neck dissection in medullary thyroid carcinomas remains unclear; thus, recent clinical guidelines have deferred the recommendation of lateral neck dissection. This review is to assess the role of lateral neck dissection in treatment of clinically overt medullary thyroid carcinoma.

Methods

A meta-analysis was performed on full-text publications written in English sourced using Embase and Medline databases. Publications with data regarding lateral neck dissection and clinical outcome were included.

Results

The frequently performed central neck dissection was significantly correlated with a higher biological cure rate (p = 0.047) and lower structural recurrence rate (p = 0.002). The frequency of ipsilateral lateral neck dissection was significantly negatively correlated with the rate of died of disease (p = 0.017).

Conclusion

The frequency of lateral neck dissections and rate of died of disease had a reverse correlation suggesting that prophylactic lateral neck dissection has a significant impact on survival.
