    Abstract:
    In the last 12 years in our surgical service, radical resection was performed in 142 patients with cancer of left colon and in 145 patients with rectal cancer. Extended lymphadenectomy was always realized: preaortocaval lymphadenectomy in colonic cancer; preartocaval and pelvic lymphadenectomy in rectal cancer. The incidence of C stage was 40.14% in cancer of left colon and 40.68% in rectal cancer. Neoplastic diffusion in preaortocaval lymph nodes was only in a patient with colonic cancer, never in patients with rectal cancer. The incidence of neoplastic diffusion in pelvic nodes was 3.12% (0 in superior rectum; 6.25% in medium rectum; 2.4% in inferior rectum). In 1 of 90 patients with tumour of medium or inferior rectum, we relieved tumoural involvement of pelvic nodes without neoplastic diffusion in regional nodes. These anatomo-pathological data subline: a) the low incidence of neoplastic diffusion in preaortocaval nodes in cancer of left colon and rectum; b) the importance of pelvic lymphadenectomy in cancer of medium and inferior rectum.
