Sumario:The metastasis of cervical carcinoma is associated with the lymphovascular spread. The primary objective of the present study was to determine the prognostic value of lymphovascular space invasion (LVSI) in patients with early-stage cervical cancer in Jilin, China. In this retrospective cohort study, patients with early-stage cervical cancer (stage IB-IIA) at the Second Hospital of Jilin University from February 2014 to December 2016 were included in the analysis. All included participants underwent radical hysterectomy with pelvic lymphadenectomy. LVSI was identified by hematoxylin and eosin (H&E) staining. The primary outcomes are overall survival (OS) and progression-free survival (PFS). Kaplan–Meier curves were used to calculate the patient's survival. Survival was compared using the log-rank test, while risk factors for the prognosis were assessed by Cox regression analysis. The incidence of LVSI was positively associated with the depth of stromal invasion (P = .009) and lymph node metastasis (LNM, P < .001). LVSI is an independent factor that affects OS (P = .009) and PFS (P = .006) in patients with early stage cervical cancer. LNM status is an independent factor that affects postoperative OS (P = .005). The incidence of lymphatic vessel infiltration is positively associated with the depth of stromal invasion and LNM. LVSI is an independent risk factor for the prognosis of early cervical cancer. The results suggest that further large-scale studies are needed to improve the treatment for patients with LVSI.
