Le cancer du colon, e'tude de 153 cas et comparaison avec une serie historique de 140 cas

ABSTRACT

The authors study the epidemiological, diagnostic and therapeutic features of 153 consecutive cases of colon cancers collected between 1985 and 1998. They compare the results with those of a previous study performed in the same hospital service [140 cases between 1966 and 1984]. It is a series of 79 men and 74 women [sex ratio= 1,07]. The mean age was 56,6 +/- 14 years old with 13,7% of the patients who were less than 40 years old. The operability and the resecability were respectively 98,7% and 83,7% with a global operative mortality of 7,9%. According to the Dukes classification, they were 2A stages, 73 B stages, 32 C stages and 45 D stages. Starting from 1993, 53% of the C stages an 48% of the B stages had an adjuvant chemotherapy, The comparison between our present results and those of our previous series does not show any modification in what regards the mean age, the cancer frequency in young people, the complicated forms proportion and time needed for the diagnosis by comparison to the beginning of symptomatology. The colic cancer prognostic improvement is attained through an earlier diagnosis, making it possible to reduce the developed forms and the complicated forms proportion, the consequence of which is the operative mortality decrease and the log-range survival increase
