RESUMO
Objective:To study the relationship between S-100 protein and prognosis of laryngeal carcinoma.Method:S-100 protein was observed by immunohistochemical methods using anti-S-100 protein antibody in 68 laryngeal carcinoma and 21 non-cancer laryngeal tissues.Result:The result showed that S-100 protein positive were found 43(63.24%)in 68 laryngeal carcinoma.S-100 protein positive cells were interspersed among the tumor cells and in the stroma.S-100 protein were rare in non-cancer laryngeal tissues.The five-year survival rate in patients with S-100 protein positive was significantly higher than that in patients with S-100 protein negative.Conclusion:Our result indicated that the detection of S-100 protein is of value for the prognostic analysis in patients with laryngeal carcinoma.
