| [ Summary ] |
Early duodenal cancer has been increasing over the ten year period, to date, in Japn. Unfortunately, although some progress has been made in techniques for diagnosis of early duodenal cancer and adenoma, there is no entirely reliable method of differentiating adenoma from cancer in adenoma. Therefore, some duodenal adenomas contain malignant portions, even if these lesions are diagnosed as adenoma by biopsy. From the diagnostic and therapeutic points of view, we recommend endoscopic mucosal resection for early duodenal cancer and adenoma. |
