CD34 and neoplasm: In particular, when compared the Kaplan Meier curves between groups [tumor with CD34 (+) vs. CD34 (−)] or groups [tumor with BRAF (+) vs. BRAF (−)], no difference was found in patients with detection of CD34 expression (χ2 = 0.832, p = 0.362) or in patients with detection BRAFV600E mutation (χ2 = 0.824, p = 0.364), neither in patients with detection of both CD34 expression and BRAFV600E mutation (χ2 = 0.938, p = 0.333; Figure 2).
