STOML2 and cancer: In 36 patients with poorly differentiated cancer, univariate analysis revealed that SLP-2 overexpression was associated with poor PFS (P = 0.046) and OS (P = 0.049) (Fig. 6c); Cox regression analysis showed that SLP-2 overexpression was associated with OS (P = 0.023), but was not associated with PFS (P = 0.058).
