 Prognosis of m3, sm1 esophageal cancer is good after treatment either by EMR (79 cases) or by radical surgery (56 cases), the 5-year survival rate after each treatment being 88.0% and 95.2% respectively. The overall 5-year rate was 62.2% and 80.0% when deaths due to other causes were also counted. Lymphatic invasion was found in 30.4% of the patients and lymph node metastasis was found in 15.5%, 73.3% of whom had involvement of only one lymph node.

 In the patients treated by EMR, local recurrence rate was 8.2% and the lymph node recurrence rate was 6.8%. Local recurrence was re-treated successfully by endoscopic maneuver except for one case involving lymph node recurrence. If lymphatic invasion is positive in the resected specimen after EMR, 33.3% of these patients may possibly have lymph node metastasis. The patients of m3, sm1 esophageal cancer indicated as suitable for EMR have 6.8% of lymph node metastasis. They should by followed up every 6 months after EMR by CT and EUS. Accurate preoperative diagnosis for lymph node metastasis is desirable.
