Background and Objectives
Although the thyroid cancer occurs in every one of 1000 pregnant women, the optimal timing of surgery is still uncertain. The aim of this study is to propose the timing of surgical management of papillary thyroid cancer in pregnant woman.

Materials and Methods
The authors reviewed the medical records of papillary thyroid cancer patients diagnosed during pregnancy in our hospital from May 1st, 2013 to April 30th, 2015. We analyzed the changes of radiologic and pathologic findings during prenatal and postpartum period.

Results
17 of 4978 patients were diagnosed with papillary thyroid cancer. 10 of 17 patients enrolled in this study. Each size of thyroid cancer in 1st trimester, in 2nd trimester, in 3rd trimester, and after delivery was 11.30±6.01 mm, 12.74±7.79 mm, 13.82±9.93 mm, and 13.82±8.19 mm, respectively. No patient showed the recurrence or death after surgery.

​Conclusion
There was no statistical significance on the prognosis of papillary thyroid cancer during prenatal and postpartum period. The authors propose that the surgical treatment of papillary thyroid cancer diagnosed during pregnancy could be delayed after delivery.
