Figure 1 from Two Molecular Subgroups Predict Most Recurrences in Advanced Laryngeal Squamous Cell Carcinoma

Kaplan–Meier RFS (median follow-up of 24 months). A, Patients with elevated VEGF-A at tumor depth (RQ > 2; n = 35; mean = 7.06 ± 5.38) had significantly worse outcomes than those with lower expression (RQ ≤ 2; n = 25; mean = 1.17 ± 0.48; log-rank P = 0.0001 and χ2 = 14.8). B, VEGF-A expression at the tumor surface was not prognostic (log-rank P = 0.170).
