Among 22 patients with lateral lymph node involvement, the rate of simple obturator and internal iliac lymph nodes metastasis is 54 5%; The rate of simple external iliac and common iliac lymph nodes metastasis is 18 1%.
Results:In 36 cases,there were 19cases with lymph node metastasis,of them 36.3%(5/19)were positive in lateral lymph node metastasis. The positive rate of lateral lymph node metastasis was 13.9%(5/36) in all cases.
Results: The average positive rate of incisal margin for posterior intestinal canal of experiment team and control group were 13.51% and 41.15%,respectively. The partly recrudescent rate were 13.51% and 58.82% respectively. The positive rate of lateral lymph node of Experiment team is 32.43%.
Conclusion:It is necessary that lateral lymph nodes were dissected for all patients with advanced lower rectal cancer below peritoneal fold,besides 3 groups of superior lymph node must be dissected. This protocal can prevent postoperative cancer recurrence.
Results Seven cases of group B had the side way lymph nodes metastasis,the rate of metastasis was 23.33%. The side way lymph node metastasis rates in low differentiation and mucus cancer was significantly higher than that of high and middle differentiation cancer (P<0.05).
The 3-year survival rate in group A was higher than that of group B. Conclusions Side way lymph node cleaning in treatment of low rectal cancer is useful in decreasing the local recurrence, improving living quality and increasing survival rate.
PURPOSE: The aims of this study were to determine the rate of lymph node micrometastases and to evaluate their prognostic value in lateral lymph nodes in lower rectal cancer at or below the peritoneal reflection.
After nasal submucosal administration of the DC, tumor-antigen-specific cytotoxic T cells were detected in the ipsilaterals but not in the contra lateral lymph nodes.
