摘要
Objective： To study the relationship between Survivin and VEGF proteins in a subgroup of patients with squarnous carcinoma of larynx. Methods： 108 cases of squamous carcinoma of larynx with clinical data were collected and expressions of Survivin and VEGF in peripheral blood were investigated by enzyme-linked immunosorbent assay （ELISA）. Results： Expressions of Survivin and VEGF were significantly associated with T stage, N stage and metastasis of squamous carcinoma of larynx. The patients with Survivin or VEGF over-expressions presented lower survival rate, respectively, as compared to those of low-expression （P 〈 0.05）. The survival rate in squamous carcinoma of larynx patients with Survivin and VEGF dual over-expressions was significantly lower than that of patients with dual low-expression （P 〈 0.05）. Multivariate analysis indicated that both Survivin and VEGF over-expressions in squamous carcinoma of larynx peripheral blood samples were strong independent factors of poor prognosis in squamous carcinoma of larynx patients. Conclusion： Survivin and VEGF over-expressions are independent prognostic factors for the patients with squamous carcinoma of larynx. These results also suggest that peripheral blood Survivin and VEGF expressions are valuable prognostic markers for prognosis prediction in squamous carcinoma of larynx patients.
