Abstract:
In a retrospective study the diagnostic validity of sonography (US), computer-tomography (CT), scintigraphy (SC) and serum alkaline phosphatase (AP) in the detection of liver metastases was evaluated in 929 patients with malignant tumors: ovary (n = 367), mamma (n = 189), endometrium (n = 181), cervix (n = 162), fallopian tube (n = 10), vulva (n = 20). Definitive diagnosis was confirmed by autopsy (n = 51), surgical intervention (n = 297) or follow-up (n = 581). Specificity, sensitivity and overall accuracy of the different methods in the indication of liver metastasis were as follows: CT (n = 58) 81%, 98%, 93%, US (n = 929) 70%, 94%, 90%, SC (n = 512) 66%, 85%, 81%, AP (n = 325) 68%, 93%, 87%. In the last examination period, US and CT reached comparable results. In view of efficiency, AP and US would appear suitable for routine control in gynecological malignancies.
