Expression of FHIT in oral squamous cell carcinoma and significance / 吉林大学学报(医学版)

Objective To study the expression of fragile histidine triad(FHIT) in oral squamous cell carcinoma(OSCC),and discuss its role and significance in OSCC.Methods Immunohistochemical method was used to detect the expressions of FHIT in 48 cases of OSCC and 26 normal oral mucosa.Results The positive expression rate of FHIT in normal oral mucosa was 76.92%(20/26).Among 48 OSCC patients,the positive rate of FHIT(43.75%) was lower than that in normal oral mucosa(P0.05),but FHIT protein content was significantly associated with differentiation(P
