Tumour markers
One hundred and eighty-six patients had secretory tumours with a
demonstrably elevated tumour marker at diagnosis: alpha-fetoprotein
(AFP) in 157 (81.8%), beta-human chorionic gonadotropin (β-HCG) in 28
(14.6%) and oestradiol in one patient (0.5%). The remaining six
patients had an elevated lactate dehydrogenase (LDH).
