We further assessed whether FLOT1 expression was clinically correlated with lymph node metastasis in 169 paraffin-embedded, archived NPC tissues, including 57 lymph node metastasis-negative (LN−) cases and 112 lymph node metastasis-positive cases (LN+; Supplementary Table 1). Here, FLOT1 is linked to nasopharyngeal carcinoma.
