    5. Conclusions
    This study developed an accurate LNR-based prognostic model for predicting the survival outcome after D2 surgery in gastric cancer patients with metastasis to more than 15 regional MPP+ Iodide nodes. This model might assist clinicians in the prognostic stratification of such patients and convince eligible patients to receive adjuvant chemotherapy.
