 Development of CV(caliber variation)was examined by magnifying endoscopy with NBI in 12cases with superficial-type esophageal cancer. In addition, development of SMA-positive blood vessels in the superficial layer of the mucosa and VEGF expression were examined immunohistochemically. CV was observed by magnifying endoscopy with NBI in all four cases with SM cancer. Immunohistochemistry revealed development of blood vessels with SMA-positive vascular smooth muscle in the superficial layer of the mucosa and VEGF was positive in all these cases. CV was detected in 2 of 8 M cancer cases(SMM, 7 ; DMM, 1)and invasion depth in DMM and SMA. SMA-positive blood vessels were observed immunohistochemically in the superficial layer of the mucosa in three cases with M cancer. VEGF was positive in two cases with M cancer and CV was detected in one case. These results revealed the possibility that development of CV is a finding suggestive of SM cancer in cases with Barrett's esophageal cancer. .
