37 Quantitative evaluation of lymph-vascular space invasion (LVSI) in patients affected by endometrial cancer: prognostic and clinical implications
Objectives Lymph-vascular space invasion (LVSI) is associated with an increased risk of recurrence. Usually, the interpretation of LVSI is just qualitative, as presence or absence. The aim of this study is to examine the quantitative analysis of LVSI. Methods Retrospective multicentre study. It included 2300 consecutive patients who received a histologically confirmed diagnosis of endometrial cancer between January 2000 and December 2018 at the Gynaecologic Oncology Unit of two tertiary hospitals in Italy. Results The rate of lymph node metastasis increased from the 5% in patients with no LVSI, to 15% in patients with focal LVSI and 33% in those with diffuse LVSI (p Conclusion The presence …
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…
