Étude histopathologique des cancers mammaires dans l’ouest algérien: à propos de 81 cas

Abstract

De par son incidence, le cancer du sein reste le cancer le plus fréquent chez la femme. Cette incidence est faible avant 35 ans et augmente avec l'âge. Il s'agit d'une pathologie mammaire hétérogène avec des variations interindividuelles. Notre étude a porté sur une analyse histopathologique de 81 cas de tumeurs mammaires malignes colligées au niveau du laboratoire d'anatomie pathologique du Pr Bourouis (Oran, Algérie). L'objectif de cette étude est de déterminer les fréquences de chaque type tumoral et d'analyser son aspect histologique et pronostique. Les résultats obtenus ont révélé deux cas de sarcomes et 79 cas de carcinomes. Le type histologique le plus fréquent est le carcinome canalaire infiltrant avec un pourcentage de 76,54 % des cas. Selon la classification histopronostique Scarff-Bloom-Richardson (SBR), 70 % des cas appartiennent au grade III. L'examen des curages ganglionnaires indique que 80 % de ces derniers sont envahis par le processus tumoral.Abstract Through its impact, breast cancer remains the most frequent in woman.
