Background And Objectives:
Lymph node metastasis was the most important prognostic factor in gastric cancer. Patients with node-negative gastric cancer presented better survival. However, some of them would die of the disease. The aim of this study was to evaluate the prognostic factors of patients with node-negative gastric cancer.
Methods:
From 1996 to 2007, 4,426 patients had undergone curative D2 gastrectomy for gastric cancer at the Fudan University Shanghai Cancer Center. Patients with node-negative gastric cancer who underwent curative D2 gastrectomy with more than 15 lymph nodes dissected were selected into this study. The prognostic value of pathological features was investigated.
Results:
This study included 234 patients with node-negative gastric cancer. The 5-year overall survival in these patients was 85 %. The factors correlating significantly with overall survival on univariate analysis included age (P = 0.016), depth of invasion (P = 0.000), tumor size (P = 0.013), tumor site (P = 0.000), histological grade (P = 0.009), lymphatic tumor emboli (P = 0.014), vascular tumor emboli (P = 0.005), and nervous invasion (P = 0.033). Multivariate analysis showed that lymphatic tumor emboli (hazard ratio (HR) = 7.270), vascular tumor emboli (HR = 3.010), and depth of invasion (HR = 2.735) were defined as independent prognostic factors.
Conclusion:
Among patients with node-negative gastric cancer and higher risk for recurrence, the use of adjuvant therapies should be considered.
