Abstract:
In order to approach the significance of PCNA,P
53in laryngeal carcinoma,immunohistochemical staining method was used to detect the proteins of PCNA,P
53 in 56 cases of squamous cell carcinoma of larynx and 7 cases of normal larynx tissues.The positive incidences of PCNA,P
53in laryngeal carcinoma were 71.4% and 51.8%,respectively.No protein was found in normal tissuse.Overexpression of PCNA, P
53were positive correlated to clinical stage,lymphatic node metstasis and patient survival rates of this tumor.The overexpression of PCNA,P
53 are closely correlated with the poor prognosis of laryngeal carcinoma.
