다국어 초록 (Multilingual Abstract)

Esophageal carcinomas are relatively rare among those of arising in gastrointestinal tract, but are important because of the high mortality and poor prognosis they have. This report was attempted to deal with an endoscopicopathological evaluation of 114 cases which had been diagnosed as esophageal cancer in the Department of Internal Medicine, Chonnam University Hospital during the period from January 1975 to August 1984. The results were as following 1) In 114 cases of esophageal cancer, male to female ratio was 7.8: 1. The peak age incidence was the 6 th decade with 39.5% 2) The tumors located at the middle one third in 48, at the lower one third in 40, at the cardia in 17, and at the upper one third in 9 cases. 3) Endoscopically, 53 cases were elevated types, 22 cases were stenotic, the remainings were 18 depressed, 15 superficial, and 6 unclassified types in order of frequency. 4) Endoscopic biopsy positive rate was 65%, in 114 cases of esophageal cancer and there was no significant difference in the involved sites but significant difference in the endoscopic tumor types: In elevated types, biopsy positive rate was 81% and in stenotic types 36% 5) Histological classification of the esophageal cancer in our study was squamous cell carcinoma in 56 cases, adenocarcinoma in 14 cases, undifferentiated carcinoma in 3 cases, and mucinous cell carcinoma in 1 case in order of frequency. 6) The histopathological types of the non-malignant cases were normal mucosa in 23 cases (59.5%), inflammation in 8 cases(20%), dysplasia in 5 cases(12.5%), hyperplasia in 2 cases (5.0%), and ulceration in 1 case(2.5%).
