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.

Objective To investigate the clinical characteristics and surgical strategies of papillary thyroid carcinoma(PTC) combined with Hashimoto 's thyroiditis(HT) . Methods The retrospective study was performed in 82 patients of PTC with HT patients among 334 PTC patients. Results The results showed that all patients underwent surgical treatment. According to the patient's condition，we performed glandular and isthmus resection， total or near total resection and different range of cervical lymph node dissection. The postoperative pathology confirmed as PTC. Compared with the PTC group， the female in PTC+HT group's cervical lymph node negative ratio was significantly increased， and the maximum diameter of the lesion was significantly reduced(all P<0.05) . The rate of transient hypocalcemia was significantly higher in PTC+HT group than that in the PTC group (P<0.01) . Conclusions PTC combined with HT is more common in women. HT may have a certain inhibitory effect on the invasion of PTC primary tumor and lymph node metastasis. Surgery in PTC+HT may have higher incidence of complications which should be paid more attention to. [ABSTRACT FROM AUTHOR]
