Objective > To study the epidemiology and histology of primary digestive cancers in semi-urban let areas in Burkina Faso. Methods > This was a descriptive study over 5 years conducted simultaneously in 2 regional hospitals in Burkina Faso. It included all patients treated for primary digestive cancers.

The most common histological type of cancer was adenocarcinoma (67.6%). One hundred and forty-four patients (40.9%) were diagnosed at stage 3 and 65 others (18.5%) at stage 4 of TMN staging. Therapeutically, surgery was used in 307 patients (87.2%) and chemotherapy in 63 cases (17.9%). The one-year mortality rote was 29%.
