Under survival analysis, patient’s cancer recurrence was significantly lower in those patients with low level of pgRNA in FNT samples (Figure 6A), low level of OCT4 in FNT samples (Figure 6B), and the tumor size smaller than 5.5 cm (Figure 6C), but not other factors such as no tumorous vascular invasion (Figure 6D) and differentiation (Figure 6E), indicating that pgRNA and OCT4 in FNT could be a significant predictive factor for cancer recurrence. This evidence concerns the gene POU5F1 and cancer.
