To reduce the mortality from ovarian cancer various studies by transva
ginal color Doppler (TVCD) sonography and serum CA-125 tumor marker, a
lone or in combination, have been performed. Relatively poor specifici
ties of CA-125 and transvaginal conventional sonography can be improve
d with the use of TVCD. Furthermore, high specificity can be achieved
on screening asymptomatic postmenopausal women by combining serum CA-1
25 measurement with TVCD. Combining tests should not necessarily incre
ase the overall cost of screening because of the expected decrease in
the number of unnecessary surgical interventions. Until the results of
large, prospective studies are available, the efficacy of potential t
ests for screening of ovarian cancer will remain unproven and they sho
uld not be used to screen apparently healthy women outside of scientif
ic interest.
