Background: Although patients with early gastric cancer have good prognosis, recurrence after treatment may occur. Lymphovascular invasion (LVI) in gastric cancer has long been suggested as a poor prognostic indicator. This study sought to evaluate the prognostic effect of LVI in patients with early gastric cancer.

Methods: From 2005 to 2016, 6516 patients with early gastric cancer who underwent radical gastrectomy were analyzed. The patients were categorized according to LVI and lymph node (LN) status.

Results: LVI was present in 853 patients (13.1%). Patients with LVI or LN metastasis had more aggressive tumor characteristics than patients without both LVI and LN metastasis. The overall and relapse-free survival in patients with LVI were significantly worse than in patients without LVI. When we compared the survival rate of patients stratified by LVI and LN status, there was a significant overall and relapse-free survival difference between patients without both LVI and LN metastasis compared with those with LVI but without LN metastasis (p < 0.001). The overall and relapse-free survival of patients with LVI but without LN metastasis were similar to those without LVI but with LN metastasis (p = 0.818). Patients with LVI or LN metastasis showed a high frequency of recurrence (p < 0.001). Multivariate analysis showed that LVI and LN status were independent risk factors for relapse-free survival of early gastric cancer patients.

Conclusions: Early gastric cancer with LVI is associated with poor prognosis and frequent recurrence. When predicting the prognosis of patients with early gastric cancer, LVI should be considered.
