- W3028874906 abstract "Objective To investigate the regulations of lymphatic metastasis of rectal carcinoma which can provide help of clinical diagnosis and treatments.Methods A retrospective analysis was performed of 222 patients with rectal carcinoma who underwent surgical resection from November 2006 to January 2012.Summarize the relevance of each factor and lymph node metastasis by logistic regression analysis.Results (1) Gender and lymph node metastasis has no significant correlation (x2 =0.000,P ＞ 0.05).(2) Lymph node metastasis rate reduced with increasing age and the difference was statistically significant (x2 =5.001,P ＜ 0.05).(3) There is no significant difference between tumor location and lymph node metastasis rate (x2 =0.052,P ＞ 0.05),when the distance between anal rectal cancer and the anus was closer,the tendency of lymph node metastasis was higher,and there has the obvious correlation with lymph node metastasis rate of its size,2.5 to 5.5 cm group and more than 5.5 cm lymph node metastasis rate was significantly higher than less than 2.5 cm group with a significant difference (x2 =2.267,P ＜ 0.05).(4) Tumor invasion of the intestinal circumference was closely related with lymph node metastasis rate (x2 =2.323,P ＜0.01).(5) Lymph node metastasis rate was closely related to the depth of invasion,metastasis rate increased with the depth of invasion increasing(x2 =2.277,P ＜0.05).(6) Lymph node metastasis was significantly higher with the decrease of the degree of tumor differentiation (x2 =4.322,P ＜ 0.01).Logistic regression analysis showed that the degree of tumor differentiation,infiltration and invasion of intestinal circumference diameter lymph node metastasis influential,OR (95 ％ CI) was 5.562 (0.105-0.444),2.178 (0.144-0.971),1.563 (0.038-8.613) respectively (P ＜0.01).Conclusion The lymphatic metastasis of rectal carcinoma is related to age,tumor size,intestinal circumference invasion,depth of tumor invasion and the differentiating degree of the tumor,and the differentiating degree is the major factor.Key words: Colorectal cancer; Lymph node metastasis; Clinical law; Analysis" @default.
