PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
Between Jan 1986 and Dec 1997, 323 breast, 94 colorectal, 36 renal and 17 p
rostate cancer patients were serially followed-up with CEA-TPA-CA15.3, CEA-
TPA-GICA-CA72.4, GICA-TPA-ferritin associations and PSA respectively. All p
atients presenting bone scintigraphy (BS) with equivocal interpretation and
concomitant constant elevation (CE) or progressive increase (PI) in one or
more of tumor markers (TM) were selected for computed tomography (CT), exc
ept those with equivocal BS of ribs, who were evaluated by skeletal x-ray.
In non relapsed patients affected by the different cancer types, concomitan
t dynamic TM evaluation allowed to decrease by 13% up to 48% the equivocal
BS subjects to be studied further with CT or x-ray. Moreover TM selected fo
r radiological investigation 81% to 100% of those with skeletal metastases
and equivocal BS. These data point out the relevant role of TM in improving
BS specificity and in selecting those who need further radiological examin
ations.
