Core Tip

Core Tip: Clinical information was collected from 230 gastric cancer patients who received neoadjuvant chemotherapy (NAC) from January 2016 to December 2020. Least absolute shrinkage and selection operator logistic regression analysis was performed to find the possible predictors for a nomogram model for prediction of response to NAC. The nomogram combining tumor location, histological differentiation, clinical T stage, and carbohydrate antigen 724 showed satisfactory predictive power to response of NAC and could be used by gastrointestinal surgeons to identify an optimal treatment strategy for advanced gastric cancer patients.
