TFE3 and neoplasm: The results of the multivariate analysis revealed that TFE3 rearrangement (HR = 4.6; 95% CI 1.1–21.2; p = 0.05) is as an independent prognostic factor associated with recurrence, in conjunction with tumor size (HR = 2.53; 95% IC 2.01–6.16 p = 0.006) and the presence of metastasis (HR = 4.36; 95% IC 2.86–7.39; p < 0.001).
