Furthermore, multivariate analysis for PFS including FIGO stage, histological type, residual tumour, positive peritoneal cytology and Twist immunoreactivity revealed that FIGO stage and positive Twist expression were independently significant prognostic factors (FIGO stage: RR, 3.861; 95% CI, 1.615–9.231; P<0.0001; positive immunoexpression of Twist: RR, 4.436; 95% CI, 2.275–8.652; P<0.0001) (Table 3). The gene discussed is TWIST1; the disease is neoplasm.
