In a study done in IPO-Porto, that represented the first European series of long-term follow-up after endoscopic resection for gastric lesions, involving 162 patients and 195 lesions, it was shown that 90% of early gastric neoplasias could be cured by gastric mucosectomy without the need for surgery. More importantly this technique did not compromise the global survival of the patients since in more than 10 years of follow-up no patient died because of gastric cancer.
