This study aims to explore the effects of long non-coding RNA H19 (lncRNA H19) and microRNA let7a (miRNA let7a) expression on the prognosis of thyroid cancer (TC). This may aid in the discovery of more effective treatment and prognosis approaches for TC. Between January 2008 and January 2011, 131 TC tissues and adjacent tissues were obtained from TC patients. An additional 122 normal thyroid tissues were also collected as normal controls from patients with benign thyroid lesions. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect lncRNA H19 and miRNA let7a mRNA expression. Five-year follow-ups were conducted. A Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic values of lncRNA H19 and miRNA let7a in TC. The Kaplan-Meier method was applied to analyze the 5-year survival rate of TC patients. Univariate and multivariate factor analyses were employed to analyze the prognostic factors of TC. The lncRNA H19 mRNA expression was higher while the miRNA let7a mRNA expression was lower in TC tissues than, in the normal thyroid tissues and adjacent tissues. The area under the ROC curve (AUC) of lncRNA H19 and miRNA let7a were 0.801 and 0.116, with sensitivity at 72.5
