题1.答案为A。临床上对于胃癌在大体形态上分为早期胃癌和进行期胃癌,这是根据胃癌的基底部是否侵犯粘膜下层以外的胃壁组织而言,它不依肿块在胃内的大小范围和区域淋巴结是否有转移而定,也不以肿块是否有溃疡和出血而定,也不以行根治术后存活时间长短来定。临床上常见到早期胃癌出现区域淋巴结转移的情形,有的转移到第一站,甚至有的转移到第三站淋巴结。早期胃癌中隆起型突出于胃腔内,凹陷型的中央亦可有深达5mm 以上的溃疡形成。
Question 1. The answer is A. Clinically, gastric cancer is roughly divided into early gastric cancer and advanced gastric cancer. It is based on whether the basement of gastric cancer invades the gastric wall tissue other than the submucosa. It does not depend on the size of the tumor in the stomach and whether there is regional lymph node metastasis. However, it is not determined by the presence or absence of ulcers and bleeding, nor by the length of survival after radical resection. Clinical lymph node metastasis is common in early gastric cancer. Some metastases to the first station, and some even to the third station lymph node. In early gastric cancer, the bulge type protrudes from the stomach cavity, and the depression type center may also have an ulcer depth of 5 mm or more.
