早期胃癌的概念于1962年由日本第四次内窥镜学会会长田坂教授首先提出,认为病变仅限于粘膜和粘膜下层者,称为早期胃癌,以后对此命各认识不完全一致,有人认为此期一部分病例已有淋巴结转移,就不能称为早期胃癌。目前多数学者认为癌病变未超越粘膜下层,不论有无淋巴结转移统称为表浅型胃癌或粘膜内癌。虽然对早期胃癌的概念各家理解不尽相同,但早期胃癌与表浅胃癌亦多通用。
The concept of early gastric cancer was first proposed in 1962 by Prof. Tian Ye, the president of the Fourth Endoscopic Society of Japan. He believed that the lesions were limited to the mucous membranes and submucosa, and they were called early gastric cancer. At this stage, some cases had lymph node metastasis and could not be called early gastric cancer. At present, most scholars believe that cancerous lesions do not exceed the submucosa, regardless of lymph node metastasis collectively referred to as superficial gastric cancer or intramucosal cancer. Although the concept of early gastric cancer is not entirely the same, early gastric cancer and superficial gastric cancer are common.
