Prognostic value of pretreatment contrast-enhanced computed tomography in esophageal neuroendocrine carcinoma: A multi-center follow-up study

Figure 2 A typical case of esophageal neuroendocrine carcinoma. A: Axial contrast-enhanced computed tomography image of a 67-year-old man with mildly enhanced esophageal neuroendocrine carcinoma in the middle segment of the esophagus (cT2N0M0). The patient showed a good treatment effect from postoperative adjuvant chemoradiotherapy with 26.13 mo and 35.6 mo of progression-free survival and overall survival, respectively; B: Sagittal-enhanced image of the patient. The tumor was 20 mm in length and exhibited marked enhancement; C: Pathological specimen of the patient; D: Histological image of the patient. Hematoxylin and eosin staining at × 10 magnification.
