English to Spanish Medical Medical (general)

Endoscopic appearance alone is an imperfect index for malignancy, however. In one series of 87 gastric ulcerations that eventually proved to be benign, the endoscopic appearance was deemed benign in only 73 cases (84%), malignant in 4 cases (5%), and indeterminate in 10 cases (11%). Conversely, among 20 proven gastric malignancies, the endoscopic appearance was deemed benign in 6 cases (30%), malignant in 12 cases (60%), and indeterminate in 2 cases (10%).
