Core Tip

Core tip: Little information is available regarding the effects of D2 lymphadenectomy and postoperative chemotherapy in patients with node-negative early gastric cancer. Data of 311 gastric cancer patients without lymph node metastasis were analyzed retrospectively. Results showed that D2 lymphadenectomy could improve the survival rate of patients with pT3-stage tumor. However, there was no evidence of a survival benefit from postoperative chemotherapy. In conclusion, it is recommended that D2 lymphadenectomy with gastrectomy be applied for node-negative patients with pT3 gastric cancer whereas the effects of postoperative chemotherapy in patients with node-negative early gastric cancer need to be further studied.
