Currently the only tumour marker to have a well-defined and validated role
in the management of ovarian cancer is CA125. Changes in the level of CA125
can be used as a reliable indication of response or progression according
to various criteria, but it does not yet have a clear place in diagnosis or
prognosis. Its value as part of a screening tool and during routine follow
-up remain the subject of ongoing trials. Other markers remain experimental
and do not have a well-defined contribution to make at present. (C) 2000 C
