Brief Summary

Objective: To analyze the survival of patients with a reduction in the number of resected LN in patients submitted to neoadjuvant and total excision of the mesorectum with rectal cancer. Expected results: Survival rate between patients Complete Pathologic Response with less than 12 LN and 12 or more LN. To determine the difference in survival between patients with less than 12 LN in complete versus incomplete response.
