What is the prognostic importance of lymphovascular space invasion in the absence of lymph node metastasis for early-stage endometrial cancer?
Objective: The aim of this study is to analyze the prognostic role of lymph-vascular space invasion (LVSI), evaluated in a semi-quantitative fashion on prognosis of early stage, low risk endometrial cancer (EC). Methods: We enrolled patients who underwent surgery for endometrial cancer between 2003 and 2018 in two referral cancer center. All patients had endometrioid EC, G1–G2, with myometrial invasion <50%, and no lymph-node involvement. LVSI was analyzed in a semi-quantitative way, according to a 3-tiered scoring system in absent, focal and substantial. Results: Among 524 patients, any positive LVSI was found in 57 patients (10.9%) with focal LVSI (n=35, 6.7%) and substantial LVSI (n=2…
351 Substantial lymph-vascular space invasion (LVSI) as predictor of distant relapse and poor prognosis in low-risk early stage endometrial cancer
Objective To evaluate the prognostic role of LVSI, evaluated in a semi-quantitative fashion on prognosis of early stage, low risk endometrial cancer (EC). Methods We enrolled patients who underwent surgery for EC between 2003 and 2018 in two referral cancer center. All patients had endometrioid EC, G1-G2, with myometrial invasion Results Among 524 patients, any positive LVSI was found in 57 patients (10.9%) with 6.7% (n=35) focal LVSI and 4.2% (n=22) substantial LVSI. Substantial LVSI was associated to higher rate of G2 (p Conclusions Substantial LVSI represents the strongest independent risk factor for decreased survival and distant relapse, indicating a role for potential hematogenous dis…
