Objective To evaluate the markers which contribute to diagnosis and prognosis of thyroid neoplasm. Methods The references about thyroid markers in recent years were reviewed. Results CD26 and galectin-3 could be regarded as a simple, potent markers to differentiate thyroid carcinoma in preoperative diagnosis, CD97 was a specific marker for undifferentiated thyroid carcinoma and its metastasis, CD15 and telomerase could be used in fine-needle aspirate biopsy (FNAB) of thyroid mass, and to improve its diagnostic evaluation, RET/PTC was mainly expressed in thyroid medullary carcinoma, oncofetal fibronectin (oncFN) was specific to papillary and anaplastic carcinoma, thyroid peroxidase was used to identify benign and malignant thyroid tumor. Conclusion Although there are a lot of markers for thyroid neoplasm, but there is no marker which are completely specific to certain histotype of thyroid neoplasm at present.
