术前血清LC3及MMPs联合TSH检测在甲状腺乳头状癌诊断中的价值

Value of preoperative serum LC3 and MMPs combined with TSH detection in diagnosis of papillary thyroid carcinoma

目的:本研究分析术前血清LC3及MMPs联合TSH检测在甲状腺乳头状癌诊断中的价值,为临床诊断及治疗提供参考。方法:本研究对我院诊治的甲状腺乳头状癌患者进行分析,ELISA法检测患者术前血清中TSH、MMP2/9、TIMP1/2及LC3的水平。以同期健康体检者和甲状腺良性肿瘤患者作为对照。结果:本研究发现甲状腺乳头状瘤患者血清中TSH、MMP2、MMP9及LC3水平均明显升高,而TIMP1和TIMP2水平明显降低,且与正常体检者和甲状腺良性肿瘤患者比较,差异有统计学意义(P<0.05);血清中上述参数与性别无关,而与年龄、肿瘤临床分期及直径和淋巴结肿大呈正相关性。结论:术前血清LC3及MMPs联合TSH水平检测在甲状腺乳头状癌的诊断中具有重要的参考意义。

Objective： To study the value of preoperative serum LC3 and MMPs combined with TSH detection in diag nosis of papillary thyroid carcinoma and provide reference for clinical diagnosis and treatment. Methods： A total of 80 patients with papillary thyroid carcinoma treated in our hospital from March 2010 to March 2014 were analyzed, and serum TSH, MMP2/9, TIMP1/2 and LC3 levels of patients before operation were detected by ELISA. Healthy subjects and patients with benign neoplasm of thyroid during the same period were taken as control. Results： Serum TSH, MMP2, MMP9 and LC3 levels in patients with papillary thyroid carcinoma significantly increased, TIMP1 and TIMP2 levels significantly decreased, and compared with healthy subjects and patients with benign neoplasm of thyroid, there were significant statistical differences （P〈 0.05） ; at the same time, above parameters in serum were not related to gender, but closely related to age, clinical stage and diameter of tumor as well as lymph node. Conclusions： Preoperative detection of serum LC3 and MMPs combined with TSH levels has important significance fur reference in diagnosis of papillary thyroid carcinoma.
