Characteristics, regularity and significance of lymph node metastasis in early gastric cancer / 中国实用外科杂志

ABSTRACT

The main risk factors of lymph node metastasis in early gastric cancer include tumor size, depth of invasion, lymphaticinvasion, perineural invasion, differentiation and histological manifestations. Understanding the characteristics and regularity of lymph node metastasis in early gastric cancer is helpful to evaluate the prognosis of patients, and it can also provide more choices for their treatment, which has important clinical guiding significance. Gastrectomy should be performed for patients with preoperative staging or highly suspected lymph node involvement in order to resect the tumors and select a reasonable range of lymph node dissection.
