Critères non histologiques prédictifs de malignité d’un ulcère gastrique
Non histological criteria predicture of malignancy in gastric ulcer
The goal of this survey was to describe the non-histological characteristics of malignant ulcer.
We conducted a retrospective survey of patients submitted to an endoscopic examination of the upper digestive tract in the endoscopy unit of the hospital “Point G” from January 1986 to December 1998 (12 years).
Subjects with gastric ulcer and histopathological exam were included. A biopsy was performed on 241 of the 914 subjects with gastric ulcer. Of the 214 subjects who had biopsy and histological exam, 34 (15,88 %) were diagnosed with malignant ulcer.
The mean age of subjects with malignant ulcer was of 53,50 ± 3,15 years. 76,47 % of these malignant ulcers have a diameter of 10 to 110 mm and all cases of ulcer with a diameter over 110 mm were malignant.
The malignant ulcers were located on the anterior face of the stomach in 67,64 % of cases, the bottom was soiled with necrosis and hemorrhage in 94,10 % of cases. The contours of the malignant ulcers were of rounded shape in 82,36 % of cases, excavated in 97,50 %, hard in 100 %, with a thick pad in 70,50 %.
The type of histolological lesions in all cases (100 %) was gastric adenocarcinoma.
In the absence of anatomopathological exam, cases of gastric ulcers with the above characteristics should be referred to the surgeon.
