However, by chi-square analysis, we found that the level of Hsp90 was correlated with the level of HE4, FIGO stage, survival outcome, Case type and Residual tumor of patients (HE4, P = 0.000 χ2 = 16.646; FIGO stage, P = 0.001 χ2 = 10.248; Survival P = 0.000 χ2 = 20.161 Table 5; Case type, P = 0.001 χ2 = 16.883; Ascites, P = 0.001 χ2 = 19.010). The gene discussed is HSP90AA1; the disease is Ascites.
