Objectives: We conducted a phase II trial to investigate the efficacy and safety of neoadjuvant chemotherapy (NAC) comprising S-1 and cisplatin (CDDP) followed by extensive resection in the management of resectable locally advanced gastric cancer with lymph node (LN) metastases.

Methods: Patients with LN metastases from stage II or III gastric cancer received S-1 and CDDP, as NAC criteria for LN metastases were the involvement of ≥4 nodes <2 cm or ≥1 nodes ≥2 cm as confirmed by a total body computed tomography scan. All patients underwent extensive resection including D2 gastrectomy. The primary endpoint was complete resection rate and the secondary endpoints were 3-year relapse-free and overall survival.

Results: Fifty patients were assessable for the analysis. The complete resection rate was 87.8%. Three-year relapse-free survival was 44.9% and 3-year overall survival rate was 48.0%.

Conclusions: NAC with S-1 and CDDP is safe and may improve the complete resection rate in patients with metastatic LN gastric cancer. This suggests that LN metastases would provide good target lesions in future clinical trials of NAC.
