Article Abstract

Objective: To study the rule of development of early cancer of gastric cardia in vivo in public screening.

Methods: A prospective cohort study on gastric cardiac cancer was held in the high incidence area of cancer of esophagus and stomach in China. 106 subjects had been examined regularly by endoscopy to observe the change of mucosa in high incidence area of gastric cardiac carcinoma developing at the root of gastric cardiac ridge by taking serial biopsy specimens. All specimens were diagnosed through the normal pathological processes to study the prognosis of pre-cancerous lesion of gastric cardia.

Results: The result of 106 subjects who had been observed for four years were: 1. Of 8 normal persons, 3 stayed normal, 4 turned to chronic gastritis, 1 developed early gastric cardiac cancer. 2. Of 61 persons chronic gastritis, 11 was observed to have glandular atrophy, 4 with mild atypical hyperplasia, and 2 with highly atypical hyperplasia. 3. Of 9 subjects showing atrophic chronic gastritis, 5 revealed no change, and 4 became chronic gastritis. 4. Of 22 subjects who revealed mild atypical hyperplasia, 17 resolved, 4 showed no change, and 1 advanced to highly atypical hyperplasia. 5. One person with highly atypical hyperplasia reverted to mild atypical hyperplasia. 6. Of 5 subjects with early gastric cardiac cancer without any treatment, 1 became advanced cancer, 1 still stayed in early stage, and 3 turned to atypical hyperplasia.

Conclusion: 1. The development of early cancer of gastric cardia would proceed through the stages of chronic gastritis, glandular atrophy, and atypical hyperplasia. 2. The early cancer and pre-cancerous lesion of gastric cardia is reversible, though possessing malignant possibility.
