• To compare the radiomic features of the CT scans at the time of diagnosis (T0) and at the end of the preoperative chemotherapy (T1) in order to predict the TRG with the texture analysis on the first CT scan.

• To compare the radiomic features of the CT scans at the time of diagnosis (T0) and at the end of the preoperative chemotherapy (T1) in order to predict the TRG with the texture analysis on the first CT scan. A non-good response (non-GR) has shown to be predictable with texture analysis on the pre-treatment CT scan. Therefore, we hypothesize that texture analysis could let to identify the good response patients. • To find correlation between the molecular expression of the tumor and the radiomics features. Texture analysis on the pre-chemotherapy CT scan founded that entropy and compactness were higher and uniformity lower in responders. Nonetheless the association between radiomics features and molecular expression has not been investigated yet. Therefore, we hypothesize to add some others radiomics signatures to the analysis and to find an association with the molecular expression. • To find correlation between the molecular expression of the tumor and the TRG. MSI gastric cancer has been shown to be less responsive to preoperative chemotherapy. Therefore, we hypothesize to confirm this result.
