From: Elevated levels of plasma D-dimer predict a worse outcome in patients with nasopharyngeal carcinoma
Kaplan-Meier curves of disease-free survival (A), distant metastasis-free survival (B), and overall survival (C) of NPC patients with plasma EBV DNA < 4000c copies/ml (n = 411), and disease-free survival (D), distant metastasis-free survival (E), and overall survival (F) of NPC patients with the plasma EBV DNA ≥ 4000 copies/ml, according to pre-treatment D-dimer levels.
