上海地区367例经手术和切除标本病理检查证实的早期胃癌.除11例(2.9%)无明显症状外,均有不同程度的临床症状.形态分型上Ⅰ型7.1%,Ⅱa型8.9%,Ⅱb型6%,Ⅱc型38.2%,Ⅲ型25.4％,混合型18%,癌灶直径≤1cm的小胃癌和微小胃癌78例(21.2%).胃癌浸润至粘膜层的36.7%,粘膜下层63.2%。局部有淋巴结转移者11.4%,78例小胃癌和微小胃癌淋巴结转移率8.9%.作者认为应该进一步放宽胃镜检查指征.本文中形似溃疡的Ⅱc或Ⅲ型早期胃癌占63.6%(如包括有溃疡的混合型则更高),这类病人应强调多次复查和病灶的多块多方向活检.
In 367 cases of early gastric cancer confirmed by pathological examination of surgical and resected specimens in Shanghai, except for 11 cases (2.9%) with no obvious symptoms, there were clinical symptoms of varying degrees. On the morphological classification, type I was 7.1% and type IIa was 8.9%. Type IIb type 6%, type IIc type 38.2%, type III type 25.4%, mixed type 18%, small and large gastric cancers with a diameter of ≤ 1cm (21.2%), gastric cancer infiltrating to 36.7% of mucosa, submucosa 63.2 %. 11.4% of patients with local lymph node metastases and 8.9% of lymph nodes metastases in 78 patients with small and small gastric cancers. The authors believe that the indications for gastroscopy should be further relaxed. Type IIc or type III early gastric cancer resembling ulcers accounted for 63.6% (including ulcers). The mixed type is even higher. Such patients should emphasize multiple multi-directional biopsy of multiple reviews and lesions.
