Screening for liver metastases from ovarian cancer with serum carcinoembryonic antigen and radionuclide hepatic scintiphotography.
The association between pre-operative serum carcinoembryonic antigen (CEA) and liver scanning employing technetium (99mTc)-tin colloid was investigated in 30 women subsequently proven to have primary epithelial ovarian carcinoma to determine whether these two investigations improve the detection of hepatic metastases. The upper limit of normal for CEA (greater than or equal to 5 ng/ml) did not represent the optimal levels for use in predicting ovarian carcinoma nor the presence of liver metastases. But with CEA levels greater than 10 ng/ml sensitivity for liver metastases was 57%. Liver scanning alone demonstrated metastases in five out of seven patients (71%) with parenchymal liver metastases. The combination of CEA and liver scan was positive in six out of these seven patients (86%).
