[Assessing the extent of gynecologic tumors by a sonographic tumor score with special reference to ovarian cancer].

Ultrasonic findings in 1317 operatively confirmed gynecological tumors were classified according to five degrees of homogeneity: I, clearly outlined solitary cysts; II, clearly outlined homogeneous tumors; III, poorly defined or slightly heterogeneous tumors; IV, marked heterogeneous tumors; V, completely heterogeneous tumors. In the different groups, the rates of malignancy were: I, 0.9%, II, 1.9%; III, 17%; IV, 58%; and V, 75%. In a further study 1082 patients with a negative or doubtful result of the physical examination were investigated using ultrasound. Abnormal findings in 126 cases were able to detect 8 carcinomas, 25 kystomas, and 63 other tumors.
