Changes in tumor diameter and lymph node short diameter at the maximal level of axial images in LAGC patients before and after neoadjuvant therapy. (A) before neoadjuvant therapy, the tumor diameter measured at the maximal level of axial images was 6.17 cm, and the short diameter of lymph nodes was 3.28 cm, resulting in a diameter of all target lesions of 9.45 cm at baseline; (B) after neoadjuvant therapy, the tumor diameter measured at the maximal level of axial images was 4.70 cm, and the lymph node short diameter was 1.84 cm, which represented a reduction of 2.91 cm in the diameter of all target lesions compared with the initial diagnosis, with a reduction rate of 30.8% (2.91/9.45), and thus the efficacy was evaluated as PR
