Comprehensive prognostic signatures in thyroid cancer: A summarized review for molecular signatures construction strategies

Thyroid carcinoma (TC) is one of the most common endocrine carcinomas with an increasing rate of morbidity in recent decades. With a high risk of relapse and metastasis occurring in TC patients, it is essential to identify potential prognostic signatures for TC patients. Here, through a comprehensive review, we summarized 45 prognostic signatures for TC patients and concluded three main strategies for signature establishment after an extensive investigation. In particular, these signatures were classified according to different construction strategies, and the verification methods were summarized. Besides, we found that 18 key genes were overrepresented in reported signatures. This review provides a comprehensive understanding, systematic summary, and integrated analysis of current prognostic signatures of TC, which may help researchers to further understand cancer progression, construct prognostic signatures of TC, and guide future clinical treatment.
