Diagnosis of bone and liver metastases in breast cancer comparing tumor markers and imaging techniques.

One hundred and forty-seven patients were examined by bone scintigraphy, ultrasonography and scintigraphic scan of the liver, at different times after surgical removal of a breast cancer, to rule out skeletal and hepatic metastases. At the same time as imaging procedures, serum levels of tumor markers (CEA, TPA and CA 15-3) were determined using radioimmunometric methods. One or more markers were elevated in all 13 patients with hepatic metastases; 9 out of 46 patients with bone metastases had all serum markers normal, with a sensitivity of 80%. Combined assay of the markers proved useful, TPA and CA 15-3 showing the best sensitivity in bone metastases, and all three markers in liver metastases.

[Determination of glomerular filtration during sequential scintigraphy in the evaluation of separate renal function].

The serial renal scan, a rapid series of images obtained with a scintillation camera, is explained; it visualizes the arrival to the kidneys and the passage through the parenchyma and the pelvocalyceal system of 99mTc-DTPA, a tracer cleared by glomerular filtration. Dynamic imaging of the kidneys provides more extensive information regarding anatomical structure and renal function that cannot be obtained by other noninvasive techniques. Computerized data analysis provides a lot of parameters, such as global and parenchymal transit times, useful in differentiating obstructive from non-obstructive uropathy, and total and separate glomerular filtration rate. 99mTc-DTPA computer-assisted scintigraphy is recommended as a routine method in nephro-urologic conditions where an accurate evaluation of separate renal function is required.
