Abstract


Objective: To investigate the clinical diagnosis and treatment of thyroid microcarcinoma . Methods: A retrospective analysis of the clinical data from January 2002 to October 2009 menstrual preoperative and postoperative pathology confirmed 69 cases of thyroid microcarcinoma patients . Results: 69 cases of thyroid microcarcinoma patients , of which 49 cases ultrasound prompted thyroid nodules with microcalcifications and suspected thyroid cancer . Four cases of preoperative fine needle aspiration needle aspiration cytology , two cases diagnosed with thyroid cancer . The preoperative cervical lymph node biopsy in three cases , two cases diagnosed as papillary thyroid carcinoma cervical lymph node metastasis . Pathological diagnosis shows : 66 cases of papillary carcinoma ( 95.7 %) , follicular carcinoma in 2 cases ( 2.8% ) , medullary carcinoma (1.4% ) . The coexistence of thyroid microcarcinoma with benign thyroid lesions 64 cases . Intraoperative frozen section examination confirmed 41 cases of thyroid microcarcinoma . After paraffin pathological diagnosis of 28 cases of thyroid microcarcinoma . The patients by paraffin pathologically diagnosed patients with thyroid microcarcinoma secondary remedial surgery . Thyroid microcarcinoma complex issue after the second surgery . The patients were followed up for 2 months to 7 years , except 1 patient 3.5 years residual thyroid micro cancer recurrence , the remaining 68 cases of thyroid microcarcinoma patients had no recurrence and metastasis . Conclusion: The preoperative diagnosis of thyroid microcarcinoma more difficult , the high rate of misdiagnosis and missed diagnosis rate . Thyroid microcarcinoma often coexist with nodular goiter and other thyroid benign and malignant lesions often concealed, thereby enhancing thyroid microcarcinoma missed diagnosis and misdiagnosis rate . Color Doppler ultrasound examination prompted thyroid nodule microcalcifications of of thyroid microcarcinoma the diagnosis has high specificity , preoperative ultrasonography can improve thyroid microcarcinoma rate of preoperative diagnosis and intraoperative frozen biopsy may improve thyroid microcarcinoma intraoperative diagnosis rate . Significantly to reduce of thyroid microcarcinoma the recurrence rate after surgery , the prognosis is good .
