ABSTRACT
Objective: To study early diagnosis and treatment of multi-primary esophageal cancer and esophageal and cardiac double primary cancer. Methods: The data of 71 cases patients of multi-primary esophageal, double primary esophageal and cardiac cancer were collected. The diagnosis was made by dye staining through gastroscopy and X-ray. Pathological examination after operation was analyzed. Results: 14 patients were diagnosed by X-ray(14/71), 69 by endoscopy (69/71), 54 early foci and 6 early stage patients were found. All of them were operated. The resection rate is 100% with no operative death. 3-year survival rate was 40 5%. Conclusion: Routine X-ray examination of esophagus or stomach, and esophageal dye-staining and/or biopsy through endoscopy are important measures for early diagnosis of multi-primary cancer or esophageal and double primary cardiac cancer prompt surgery is advised.
