ABSTRACT
This retrospective study was undertaken to determine the histoepidemiologic profile of primary digestive tract cancer based on analysis of 375 of the 2558 cases diagnosed in the Cytopathology Department of the the University Hospital Center in Brazzaville; Congo from January 1992 to December 2001. Incidence was 14.6. The sex ratio was 1:5. Age ranged from 39 to 49 ye a rs. The liver (40.2) was the most frequent location followed by the colon/rectum (30.2); s t o m a ch (26.2); and esophagus 2.1. Predisposing factors included low-fiber diet; heavy consumption of smoked foods; and history of hepatitis B and C virus infection. The most frequent histological entity accounting for 57of cases was adenocarcinoma that was observed in the esophag u s ; stomach; colon; rectum; and pancreas. Systematic screening and tre atment of pre c a n c e rous lesions in high-risk patients is necessary to reduce the incidence of digestive tract cancer

97 cancers du tube digestif sur 1010 TM ont ete recenses au CHNYO de janvier 1986 a decembre 1993 soit 9;6 per cent des tumeurs malignes. La classique predominance masculine a ete notee et l'age moyen des patients a ete de 52 ans. l'augmentation progressive des CTD au fil des annees semble liee a l'existence de lesions precancereuses et au regime alimentaire. L'etude analytique sommaire a releve la predominance du cancer de l'estomac. Il s'avere necessaire d'insister sur les methodes de prevention. Le diagnostic etant toujours tardif
