The relationship between the factors examined in the present study, clinicopathological features, and survival of the patients did not reveal any significant correlations with the exception of smoking, which was associated with microsatellite alterations (loss of heterozygosity and microsatellite instability) at the 9p21-22 locus (P = 0.04) and the immunophenotypes p53(P)/MDM2(P) (P = 0.04) and p16(Ab)/pRb(Ab)/p53(P)/MDM2(P) (P = 0.03), respectively.
