In addition, Kaplan–Meier survival analysis suggested that high BST2 expression can predict poor prognosis in patients with locally advanced NPC treated with platinum-based chemoradiotherapy, as evidenced by shorter OS (P=0.023, log-rank test; Figure 6b) and PFS (P=0.017, log-rank test; Figure 6c). Here, BST2 is linked to nasopharyngeal carcinoma.
