本研究检查了杜克氏 C 期的结肠、直肠癌的浸润深度,肿瘤大小和阳性淋巴结数目间的内在联系。结果表明肿瘤浸润深度与肿瘤大小和局部阳性淋巴结数目二者有关。淋巴结阳性但未浸润固有肌层(C_1)的肿瘤较小,而且伴有的阳性淋巴结数目也较浸润肠管各层的肿瘤为少。尽管肿瘤浸润深度与 This study examined the intrinsic relationship between Duke’s stage C colon and colorectal cancer invasion depth, tumor size, and number of positive lymph nodes. The results showed that the depth of tumor invasion was related to both the tumor size and the number of local positive lymph nodes. Tumors with positive lymph node but not infiltrating the muscularis propria (C_1) were smaller, and the number of positive lymph nodes associated with lymph nodes was less than that of tumors infiltrating each layer of the intestine. Despite the depth of tumor invasion and
