【摘要】Objective To investigate the effect of lymphadeneetomy adjacent to inferior mesenteric artery root on the prognosis of rectal cancer. Methods Clinicopathological data of 260 cases with rectal cancer undergone radical operation were analyzed retrospectively. The patients were divided into two groups. Group D2: the lymph nodes adjacent to mesenteric artery root were not excised (n=188). Group D3: the lymph nodes adjacent to mesenteric artery root were excised (n=72).Prognosis of two groups was compared during the follow-up period. Results In group D2, the 1-, 3-,5-year total survival rates (TS) were 97.3%, 87.2% and 77.1%, and tumor-free survival rates (TFS)were 93.1%, 83.0% and 76.8% respectively. In group D3, the 1-, 3-, 5-year total survival rates(TS) were 94.4%, 79.2% and 73.6%, and tumor-free survival rates (TFS) were 86.1%, 76.4% and71.0% respectively. The differences of TS and TFS between two groups were not significant according to Kaplan-Meier analysis (P＞0.05). Multivariate analysis revealed that the excision of lymph nodes adjacent to mesenteric artery root was not statistically correlated with the recurrence, metastasis and survival time after radical operation of rectal cancer. Conclusion Excision of lymph nodes adjacent
