Abstract

BACKGROUND: An accurate assessment of potential lymph node metastasis is an important issue for the appropriate treatment of early gastric cancer. Minimizing the number of invasive procedures used in cancer therapy is critical for improving the patient’s quality of life.OBJECTIVE: To evaluate the clinicopathological features associated with lymph node metastasis of early gastric cancer in patients from a single institution in China.METHODS: A retrospective review of data from 410 patients surgically treated for early gastric cancer at the First Affiliated Hospital (Nanjing, China) between 1998 and 2007, was conducted. The clinicopathological variables associated with lymph node metastasis were evaluated.RESULTS: Lymph node metastasis was observed in 12.20% of patients. The macroscopic type, tumour size, location in the stomach, depth of gastric carcinoma infiltration, and presence of vascular or lymphatic invasion showed a positive correlation with the incidence of lymph node metastasis by univariate analysis. Multivariate analyses revealed histological classification, macroscopic type, tumour size, depth of gastric carcinoma infiltration, and the presence of vascular or lymphatic invasion to be significantly and independently related to lymph node metastasis. The depth of gastric carcinoma infiltration was the strongest predictive factor for lymph node metastasis. For intramucosal cancer, tumour size was the unique risk factor for lymph node metastasis. For submucosal cancer, histological classification and tumour size were independent risk factors for lymph node metastasis.CONCLUSIONS: Histological classification, macroscopic type, tumour size, depth of gastric carcinoma infiltration, and the presence of vascular or lymphatic invasion are independent risk factors for lymph node metastasis in patients with early gastric cancer in China. Minimal invasive treatment, such as endoscopic mucosal resection, may be possible for highly selected cancers.
