溃疡与胃癌之间是否存在因果关系是长期以来激烈争论的问题。然而同一病灶内溃疡(UI)与胃癌(ca)共存(UI(+)ca)是“溃疡恶变学说”与“癌先行学说”都能接受的现象.日本内视镜学会关于早期胃癌的分类将Ⅱc早癌内部存在溃疡的定为Ⅱc+Ⅲ型;若以溃疡为主Ⅱc病变范围较小的定为Ⅲ+Ⅱc型.并强调指出,这类情况Ⅲ本身指的是良性、溃疡性病变。可见溃疡与胃癌共存于同一病灶是较普遍的现象.
Whether there is a causal relationship between ulcers and gastric cancer has long been a subject of fierce debate. However, the coexistence of ulcer (UI) and gastric cancer (UI) in the same lesion (UI(+)ca) is a phenomenon acceptable to both “ulceration malignant theory” and “cancer precedent doctrine”. The classification of early gastric cancer by the Japanese Endoscopic Society will be IIc Presence of ulcers in the presence of ulcers are classified as Type IIc+III; if the ulcer-based IIc lesions are less in range as Type III+IIc, it is emphasized that this type of condition III itself refers to benign and ulcerative lesions. It is common to see that ulcers and gastric cancer coexist in the same lesion.
