[Expression of survivin gene and its relationship with expression of p15, p16 proteins in laryngeal squamous cell carcinomas].
OBJECTIVE
: To investigate the expression of Survivin (SVV) and its relationship with expression of p15, p16 in laryngeal squamous cell carcinoma (LSCC).


METHODS
Using strep avidin-biotin complex (SABC) method, we examined the expression of SVV, p15 and p16 gene in 48 LSCC tissus samples, 24 normal laryngeal mucosa tissus samples and 24 normal laryngeal tissus adjacent to the tumors samples.


RESULTS
SVV was expression in 27 of 48 (56.3%) samples of LSCC and expression in 6 of 24 (25.0%) samples of normal laryngeal tissus adjacent to the tumors. Normal laryngeal mocosa tissus samples did not expressed SVV. Overexpression of SVV was related to the tumor site, grade, clinical stage and tumor prognosis (P < 0.05). The expression of SVV in LSCC was positive correlated with p16 expression( C = 0.52 P < 0.001), but not with p15 expression.


CONCLUSIONS
SVV may play a role in the pathway of carcinogenesis and tumor progress. It is feasible for early diagnosis and prognosis estimation. Overexpression of SVV gene and de-activation of antioncogene p16 may be play synergetic roles in the carcinogenesis of LSCC.
