目的:探讨超声在甲状腺癌颈部淋巴结转移中的诊断价值。方法:术前超声检查47例甲状腺癌患者的颈部淋巴结,超声所见与手术切除病理结果对照分析。结果:超声检查与病理结果对照,符合的淋巴结41个,符合率78.8%。淋巴结的内部回声不均、髓质变形或缺失、周边型及混合型血流预示淋巴结有转移。结论:超声检查对甲状腺癌颈部淋巴结转移具有较高的诊断价值。
【Abstract】ObjectiveTo discuss the value of thyroglobulin (TG) in diagnosis and treatment of differentiated thyroid cancer (DTC) patients. MethodsLiteratures on measurement and clinical application of serum TG were reviewed. ResultsImmunometric assay (IMA) was adopted by most clinical lab.TG antibody （TGAb） should be measured in the same sample of DTC patient.TG detection before operation is of less value in confirming diagnosis of DTC, but is helpful in differential diagnosis of histopathological type of DTC.TG detection after operation is very important in patients who had undergone total thyroidectomy.Monitoring TG after thyroid hormone withdrawal or recombinant human TSH stimulation is more sensitive to identify tumor recurrence. ConclusionMonitoring TG after total thyroidectomy has great value in followup of DTC patients.
Objective To summarize the progress in the diagnosis and treatment of thyroid cancer related genes. Methods By using the method of literature review, The literatures of thyroid cancer related gene were reviewed on the study of emerging diagnosis and treatment strategy. Results Combined detection of BRAF oncogene, RAS oncogene, RET/PTC rearrangement, PAX8-PPARγ fusion gene and its related genes, can effectively improve the prediction accuracy of the malignant thyroid nodule form benign, and has become a basis of targeted drug therapy. Conclusion In preoperative thyroid cancer, Joint detection of related gene can provide a molecular basis for the patients to guide the operation and drug treatment.
Positron emission tomography (PET) is a highly sensitive and low invasive technology for cancer biological imaging. Integrated PET/computed tomography (PET/CT) cameras combine functional and anatomical information in a synergistic manner that improves diagnostic interpretation. The role of 18F FDG PET/CT in differentiated thyroid cancer (DTC) is well established, particularly in patients presenting with elevated thyroglobulin (Tg) levels and negative radioactive iodine scan. This review presents the evidence supporting the use of 18F FDG PET/CT throughout the diagnosis and management of thyroid cancer, and provides suggestions for its clinical uses.
Objective To explore the reoperative techniques of differentiated thyroid carcinoma. Methods Clinical data of 56 patients who treated in The First Affiliated Hospital of General Hospital of PLA and General Hospital of PLA from Feb. 2011 to Feb. 2013 were analyzed retrospectively. Results All performed surgeries were successful. Surgeries took 90-150 minutes with an average of 120 minutes. Bleeding during surgeries was 70-200 mL with an average of 120 mL. Postoperative drainage was 90-210 mL with an average of 100 mL. The pathological diagnosis of the second surgery in 44 cases were as the same as the first， but there were no malignant tumor tissues of dissected glands in 12 cases. All patients had no postoperative bleeding and bucking， but 8 patients experienced hand and foot numbness， and 5 patientsexperienced transient hoarseness. Fifty patients were followed-up for 6-30 months （average 10.8 months） from the reoper-taion and 18-66 months （average 45.2 months） from the first operation， and rate of postoperative followed-up was 89.3%（50/56）. During the followed-up， 1 patient with papillary thyroid carcinoma and 1 patient with follicular thyroid carcinoma died in 44 months and 38 months respectively， 3 patients suffered lymph node metastasis at non-Ⅵ region ofaffected side， no one suffered recurrence. Conclusions For differentiated thyroid carcinoma patients who are undergoingthe second surgery， thorough whole body condition analysis should be performed and appropriate type of surgery should be chosen. By using recurrent laryngeal nerve monitoring， carbon nanoparticles for lymph node clearance， and protecting parathyroid gland to lower the possibility of postoperative complication， to improve survival rate and life quality.
