The Authors analyze a series of 441 patients affected by carcinoma of the colon operated on between June 1980 and November 1993. The incidence of the different stages of the disease according to Dukes resulted comparable to that reported in the literature as well as the incidence of morbidity and mortality. Recostruction was performed in all cases with mechanical sutures (T-L for the right colon and L-T for the left colon) and without protection enterostomy. Long-term results evaluated by actuarial methods were influenced by the stage of the disease, and not by sex or duration of symptoms. The need of early diagnosis as well as oncologically correct surgical technique is furthermore confirmed. The importance of clinical trials on adjuvant chemotherapy is emphasized in order to improve survival in patients operated for stage B and C colon cancer.
