Objectives. The purpose of this study was to investigate serum pituitary tumor transforming gene (PTTG1) expression in laryngeal carcinoma and its relationship with the clinical pathological characteristics and prognosis. Methods. Expression of serum PTTG1 was measured by enzyme-linked immunosorbent assay in 110 patients with laryngeal carcinoma and 60 patients with vocal cord polyps. Expression of the serum PTTG1 levels relationship with the clinicopathological characteristics and prognosis were analyzed. Results. In laryngeal carcinoma patients’ serum, the PTTG1 median concentration was 141.43 pg/mL (interquartile range [IQR], 111.387 to 160.837 pg/mL), significantly higher than that of the vocal cord polyp group of 94.01 pg/mL (IQR, 81.26 to 108.59 pg/mL), and the difference was statistically significant (z=–6.715, P<0.001). PTTG1 expression with lymph node metastasis, clinical stage, and patients with laryngeal carcinoma was significantly correlated with the tumor differentiation degree (P<0.05). The total survival rate of the PTTG1 high expression group was significantly lower than the low expression group, and the difference of total survival time of the two groups was statistically significant (P<0.001). Conclusion. The PTTG1 expression level can be used as an index for evaluating prognosis of laryngeal cancer. High PTTG1 expression is one of the factors of poor prognosis of laryngeal carcinoma patients.
