(4) Neither lymph node metastases nor distant metastases in neck, chest and abdomen confirmed by contrast-enhanced CT. (5) Circumferential spread of the major lesion is 2/3 or more, but not entire circumference diagnosed by endoscopy (6) Length of major lesion is 100 mm or less in longitudinal axis diagnosed by endoscopy. (7) Circumferential spread is 1/2 or less in all sub-lesions in patients with multiple lesions (8) Aged >= 18 years old (9) Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
