Figure 2
76-year-old male with esophageal cancer who obtained a grade 3 pathologic response. (a) Before NACRT, esophagography shows irregular wall stenosis in the middle esophagus with the PES of 55.6%. (b) After NACRT, esophageal wall stenosis has improved result in the PES of 33.8%, which indicates the decrease in PES of 18.8%. (c), (d) Pathological specimen of the resected esophagus shows no carcinoma cells (grade 3). Many degenerative cells with keratinization and diffuse fibrosis are seen in the submucosa and muscularis propria.
