Within the recurrent tumours, YAP1 mRNA expression was not a significant prognostic factor for patients who did not receive chemotherapy (p = 0.62) (Figure 8E); however, low YAP1 mRNA expression was associated with significantly increased OS in patients who were chemotherapy-treated (YAP1 high vs. low median survival: 28.05 mo. This evidence concerns the gene YAP1 and neoplasm.
