Figure 3 Kaplan-Meier curves for survival of the gastric cancer patients with clinically positive para-aortic node metastasis. A: Overall survival and progression-free survival of all patients; B: Overall survival of patients who underwent chemotherapy with or without D2 resection; C: Progression-free survival of patients who underwent chemotherapy with or without D2 resection; D: Overall survival of all patients assessed by overall response; E: Overall survival of all patients assessed by chemotherapy response of the primary tumor; F: Overall survival of all patients assessed by chemotherapy response of the metastatic para-aortic lymph node. CR: Complete response; PR: Partial response; SD: Stable disease; PD: Progressive disease; NE: Not evaluable.
