7 Our Results Figure 3. The odds ratio [OR] were estimated from the logistic regression model with the generalized estimating equation (GEE) repeated-measures analysis method. In the presence of tumor-pairs GSTT1 expression, invasive showed a significant association (OR = 1.29, 95% confidence interval (CI) = ; P = ). Figure 3.

11 Conclusion In the presence of tumor-pairs GSTT1 expression, invasive showed a significant association in UTUC in mid-Taiwan, which could be a biomarker for prognosis prediction (such as the invasiveness of the tumor or survival). The genotypes of GSTT1, GSTM1 and GSTP1 could help in cancer prediction for UUT-UC and maybe also in therapy decision in the near future. Further investigation with larger sample size in addition to genotype-phenotype correlation and intracellular mechanisms are our future work.
