PVT1 and metastatic malignant neoplasm in the lymph nodes: The results demonstrated that the level of PVT1 expression was significantly associated with tumor size (OR = 1.43, 95% CI: 0.95–2.14, P = 0.006), TNM stage (OR = 2.73, 95% CI: 2.14–3.49, P < 0.001), lymph node metastasis (OR = 1.95, 95% CI: 1.04–3.65, P = 0.037), or distant metastases (OR = 4.30, 95% CI: 2.57–7.19, P < 0.001) (Table 2).
