title: [Malignant stomach ulcer: diagnostic value of extemperaneous cytology and cyto-guided biopsy].
abstract: A prospective trial of extemporaneous cytology has been conducted in 113 patients with gastric ulcer. The diagnostic effectiveness was 97% but the yield of traditional biopsy in 13 patients with malignant ulcer was 52%. Cyto-guided biopsy, performed in 46 patients (8 with malignant ulcer), increased the yield to 97%.
