Abstract
In order to provide evidence for evidence-based medicine in the treatment and prognosis of laryngeal cancer in China, the meta-analysis electronically retrieved the case-control studies published in China about the Survivin expression and its association with clinical pathological features in the tissues of laryngeal carcinoma. The results showed that a total of 25 case-control studies were finally included with 1333 cases of laryngeal cancer and 528 cases of controls. The difference in the expression of Survivin between the two groups was statistically significant [OR=18.34, 95% CI (11.82, 28.47), P<0.00001]. The difference in the expression of Survivin between laryngeal carcinoma patients with lymph node metastasis or not was statistically significant [OR=0.25, 95% CI (0.17, 0.37), P<0.00001]. The expression of Survivin in clinical I-II stage group was significantly lower than in the clinical stage III-IV group [OR=0.24, 95% CI (0.18, 0.32), P<0.00001]. The expression of Survivin in patients with low/medium differentiation was significantly lower than that in those with high differentiation [OR=0.33, 95% CI (0.26, 0.43), P<0.00001]. The difference in the expression of Survivin among different T stages of laryngeal carcinoma was statistically significant [OR=0.35, 95% CI (0.21, 0.58), P<0.00001]. In conclusion, Survivin may play an important role in the occurrence and development of laryngeal carcinoma, and its high expression is related to the poor prognosis of patients with laryngeal cancer.
