Abstract:
The authors, in a group of 190 patients treated with curative surgery for colorectal cancer, have studied the correlation between lymph nodes positive of primary tumor and rising of liver metastases. Even if the B2 stage nodes were negative, liver metastases were found in 6.25% of the patients probably due to an understaging; in C1 + C2 stage the rate of liver metastases was 28.1%, however in this group has not been demonstrated a statistical correlation with the number of positive nodes as a predictive negative prognostic factor.
