Lymph node analysisis very important in colorectal cancer since it is a prognosis factor for thedisease, which will either determine the needs of adjuvant therapy, or not.The amount of identified lymph nodes per specimen suggested by the literaturevaries from 6 to 30. The purpose of this work was to show the amount of lymphnodes analyzed from operatory subjects by means of the histopathology recordsfrom 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 fourpatients had a very differentiated adenocarcinoma. Among them, 27 (42,2%) showedpositive 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 morenodes were analyzed. The average of positive lymph node was greater in undifferentiatedadenocarcinoma.
