HOXA11 and metastatic malignant neoplasm in the lymph nodes: As shown in Table 2, the meta-analytic results showed that the increased expression level of HOXA11-AS was significantly associated with more lymph node metastasis (OR = 2.06, 95% CI 1.31–3.25), and advanced tumor stage (OR = 4.217, 95% CI 2.595–6.853).
