Objective  To discuss the resection extent of primary surgery for papillary thyroid carcinoma (PTC) based on the analysis of the remaining thyroid gland residue and lymph nodes metastasis.
Methods  The clinical data of 163 patients with PTC received reoperation from January 2009 to September 2011 in our hospital were analyzed retrospectively.
Results  There were 24 males and 139 females in these patients. The age was 10-75 years old with (38.22±14.57) years old. Among 131 patients received residual thyroid thyroidectomy,88 patients were below 45 years old,and the cancer residual rate was 60.23% (53/88);the others were over 45 years old,and the cancer residual rate was 76.74% (33/43),which was no significant difference (P?=?0.062).The lymph nodes metastasis rate was 77.14% (81/105) in the patients below 45 years old and 81.13%?(43/53) in the patients over 45 years old among 158 patients received cervical lymph nodes dissection,which was no significant difference (P?=?0.958).The cancer residual rate was 74.36%?(58/78),53.66%?(22/41),50.00%?(6/12),and 0 (0/32) in the patients with the tissue less than one lobe resection,lateral lobe (isthmus) resection,lateral lobe plus opposite side subtotal resection,total or subtotal resection,respectively. The total cancer residual rate was 65.65% (86/131) and the bilateral cancer residual rate was 52.76%?(86/163) after reoperation.79.75%?(130/163) of the patients didn’t received lymph nodes dissection in the primary surgery. The lymph nodes metastasis rate was 71.21%?(94/132) and 80.58% (83/103) in the reoperation patients received central region lymph nodes dissection and cervical lateral lymph nodes dissection, respectively.
Conclusions   Multifocus is an obvious character of PTC. Patients over 45 years old have more opportunities of tumor residual than that of the youngers (below 45 years old),but the result was no statistic value. For the most patients with PTC,a smaller resection extent suggests a larger risk for cancer residual,and total thyroidectomy or subtotal thyroidectomy leads to the least possibility for the risk. Cervical lymph node is a major type for its metastasis. Proper lymph nodes dissection is an essential way to reduce recurrence and reoperation. The Revised American Thyroid Association Management Guidelines for Patients with Thyroid Nodules and Differentiated Thyroid Cancer (2009) could be a best choice for therapy of PTC. And it is proposed to take central region lymph nodes dissection during primary surgery.
