Lymph node analysis is very important in colorectal cancer since it is a prognosis factor for the disease, which will either determine the needs of adjuvant therapy, or not. The amount of identified lymph nodes per specimen suggested by the literature varies from 6 to 30. The purpose of this work was to show the amount of lymph nodes analyzed from operatory subjects by means of the histopathology records from patients undergoing colorectal cancer surgical treatment from adenocarcinoma. The average age found was 58,69 years. Seventy five patients were females (56,8%). Most patients were found to be in phase T3 of the disease (75%). Sixty four patients had a very differentiated adenocarcinoma. Among them, 27 (42,2%) showed positive nodes. CONCLUSION: The average of dissected lymph nodes was of 11,21 / specimen. Being that the probability of finding positive node was greater when 10 or more nodes were analyzed. The average of positive lymph node was greater in undifferentiated adenocarcinoma.
