Computed tomography-based nomogram of Siewert type II/III adenocarcinoma of esophagogastric junction to predict response to docetaxel, oxaliplatin and S-1

Figure 1 Measurements of maximal diameters and gross tumor volume based on portal venous phase contrast-enhanced computed tomography in a 65-year-old male with adenocarcinoma of the esophagogastric junction. A: Maximal diameters of the tumor before three cycles neoadjuvant chemotherapy with docetaxel, oxaliplatin and S-1 (DOS); B: Maximal diameters of the tumor after three cycles DOS; C: Gross tumor volume (GTV) of the tumor before three cycles DOS; D: GTV of the tumor after three cycles DOS.
