SRPK1 and metastatic malignant neoplasm in the lymph nodes: Besides higher SRPK1, larger horizontal diffusion diameter (HR = 1.961, 95% CI = 1.149–3.349, P = 0.014), positive parametrial invasion (HR = 1.979, 95% CI = 1.075–3.641, P = 0.028), positive lymphovascular invasion (HR = 2.963, 95% CI = 1.666–4.354, P < 0.001), positive lymph node metastasis (HR = 2.349, 95% CI = 1.373–4.019, P = 0.002), and advanced FIGO stage (HR = 1.899, 95% CI = 1.041–3.465, P = 0.036) all showed independent prognostic significance.
