BLACAT1 and metastatic malignant neoplasm in the lymph nodes: Moreover, high LncRNA BLACAT1 expression was associated with positive lymph node metastasis (HR: 2.29, 95% CI: 1.66-3.16, <i>p</i> < 0.00001), advanced clinical stage (HR: 2.29, 95% CI: 1.65-3.19, <i>p</i> < 0.00001) and worse differentiation status (HR: 0.58, 95% CI: 0.37-0.92, <i>p</i> = 0.02), compared to low LncRNA BLACAT1 expression.<h4>Conclusion</h4>The findings highlight that high LncRNA BLACAT1 expression might be detrimental and induce a worse prognosis for cancer patients.
