Abstract:
Objective To investigate the relationship between the location of thyroid papillary microcarcinoma and cervical lymph node metastasis. Methods The clinical data of 334 cases of thyroid papillary microcarcinoma were retrospectively analyzed. The location of the lesion, the size of the lesion, the situation of the capsule and other factors were compared in patients with central lymph nodes or/and cervical lymph node metastasis. Results The lymph node metastasis rate were 33.33% (26/104),39.81% (43/108),and 52.46% (64/122), when the papillary thyroid microcarcinoma was located at the upper pole, median pole,and lower pole respectively (P＜0.005) . There were 46 cases (46/334, 13.77%) with cervical lymph node metastasis. The metastasis rate of cervical lymph node were 21.15% (22/104), 11.11% (12/108),and 9.83% (12/122), when the papillary thyroid microcarcinoma was located at the upper pole, median pole,and lower pole respectively (P=0.003) . 3 patients (6.5%) had no central lymph node metastasis and direct skipping of the cervical lymph nod trensfer. The rate of tumor break through through the membrane in patients with cervical lymph node metastases was 30.43% (14/46), which was higher than the 19.09% (55/288) of patients without lymph node metastasis (P＜0.005).Conclusions There is a certain correlation between the location of papillary thyroid microcarcinoma and cervical lymph node metastasis.
