Figure 1A shows the representative immunostaining of CD44 at different FIGO stages of ovarian cancer. The expression of CD44 increased with the advancement of FIGO stage. Table 2 presents the association between CD44 expression and clinicopathological characteristics. High expression of CD44 was associated with higher histological grade (p = 0.014), and more advanced FIGO stage (p = 0.001). The gene discussed is CD44; the disease is ovarian cancer.
