[Malignant tumors of the stomach: apropos of 583 anatomo-clinical cases].
A retrospective study interesting 582 anatomoclinical cases of gastric malignant tumors was realised in two anatomo-pathological services of Tunis from 1970 to 1985. The average age of patients is 55 years old, with extensive ranges from 17 to 85 years old. The authors point out significative male predominance 64.6% of cases. The ulcered form is the most frequent, about 3.8% of macroscopic aspect cases. Among these last, the authors find 26.7% of ulcerating and polypoid form with invasive characteristics, and 18.83% of linitis plastica. The pyloric area localisation is the most frequent, 68% of cases. Diffuse tumors are observed in 8.47% of cases and numerous stomach localisation in 0.82% of cases. 84% of histological aspect are represented by adenocarcinoma, the most frequent of them (35%) is well differentiated type, then the poorly differentiated (20%) and atypic form (19.75%). Frequency of lymphosarcoma reaches 14.7%, the first is the centroblastic form, then lymphoblastic and lymphoplasmocytic forms. Concerning evolution, gastric cancer is an infiltrative tumor: serosal surface is attempted in 69.5% of cases, and during the first chirurgical act half cases show lymph nodes metastasis.
