| Popis: | From 1963 through 1994, 58 patients (70 lesions) with superficial esophageal cancer have been treated at the third Department of Surgery, Nihon University School of Medicine. Out of these 58 patients (70 lesions), 18 patients (20 lesions) were of the superficial and protruding type which appeared to be of the 0-I type. Of these 20 lesions, 11 were classified as 0-I p type, 8 lesions were of the 0-I pl type and 1 lesion was of the 0-I sep type Nine of these 18 patients (50%) have shown symptoms of various types of dysphagia. In 18 out of the 20 lesions, the cancer invaded the submucosal layer of the esophageal wall, while in only one lesion did the cancer invade the level of the muscularis mucosae.Concerning the height of the tumors, all lesions were over 2 mm. There were many lesions of the 0-I p type which appeared under 3 cm in length and 3 mm in height, while there were many lesions of the 0-I pl type which appeared under 3 cm in length and over 3 mm in height. However, there was no relationship between tumor height and cancer invasion. Six of the 18 patients died from a recurrence of their cancer and of these 6 deaths, 5 cancers had invaded the submucosal layer. The overall 5-year survival rate of the 0-I type superficial esophageal cancer was 53.5%. |
