a significant trendP =0.0100
The Cuzick extension of the Wilcoxon's rank sum test confirmed the presence of a significant trend of increasing MCM-2 and MCM-5 expression with increasing tumour stage ( P =0.0100 and 0.0300, respectively).
The Cuzick extension of the Wilcoxon's rank sum test confirmed the presence of a significant trend of increasing MCM-2 and MCM-5 expression with increasing tumour stage ( P =0.0100 and 0.0300, respectively).
However, when poorly differentiated and unspecified cases, which are regarded as high-grade disease, were removed from analysis, the relationship failed to reach statistical significance (Kruskal–Wallis ANOVA, Bonferroni correction, P =0.0856).
Survival analysis: population group In univariate analysis, the parameters adversely affecting survival were high grade ( P =0.0330), advanced stage ( P =0.0193), the presence of bulk residual disease ( P =0.0001), increased (⩾20%) MCM-2 expression ( P =0.0004) and increased (⩾25%) MCM-5 expression ( P =0.0100) ( Figure 5A and B ), whereas histologic type attained a marginal significance in this regard ( P =0.0900).
