ABSTRACT
Background and purpose:During recent years, the incidence of papillary thyroid micro-carcinoma (PTMC) has increased year by year. There are many differences in its diagnosis and treatment. This research investigated and summarized the clinical diagnosis and treatment of thyroid papillary carcinoma by means of analyzing the patients’ data.Methods:Sixty-one cases underwent high resolution ultrasound examination before operation, and the accuracy rate was 86.9%. All patients underwent surgical treatment. Thirty-nine patients had thyroid lobectomy and ipsilateral central lymph node dissection (CLND), 11 underwent concurrent partial thyroidectomy, 22 had total thyroidectomy and bilateral central lymph node dissection and 5 underwent concurrent cervical lymph node dissection. The incidences of central and cervical lymph node metastasis were 44.3% and 8.2%, respectively. Univariate analysis showed that the risk factors for central lymph node metastasis were age <45 years, multifocality, tumor location near or across the midline, tumor diameter≥5 mm. The rates of central lymph node metastasis were 66.7%, 60.7%, 66.7% and 53.8, respectively.Conclusion:High resolution ultrasound examination has a high sensitivity for the detection of PTMC. It is important to implement standardized and individualized treatment plan to the patients with PTMC.
ABSTRACT
Objective To discuss the treatment effect of well-differentiated thyroid carcinoma.Methods From 1992 to 2002,42 cases of well-differentiated thyroid carcinoma invading the laryngotrachea were treated in shanxi tumor hospital.Radical tumor resection were 6 cases,local shaving-off tumor resection were 32 cases and incomplete tumor resection were 4 cases.Some patients received postoperative radiotheraPy.Results In the 42patients,the overall 5-year survival rates were 76.2%(32/42).Conclusion Although well-differentiated thyroid carcinoma invaded the laryngotrachea,the operation can increase the curative effect and the patient's living standand.
