5. Summary of Data Reported and Evaluation
5.1 Animal data
No data were available to the Working Group.
5.2 Human data
Although ten cases of liver-cell tumours have been reported in
patients with aplastic anaemia, Fanconi's anaemia or paroxysmal
nocturnal haemoglobinuria treated for long periods with oxymetholone
alone or in combination with other androgenic drugs, a causal
relationship cannot be established.
The increased risk of developing liver-cell tumours could be related
to hepatic damage known to be caused by oxymetholone. On the other
hand, patients with congenital anaemias many have an intrinsically
higher risk of developing tumours; this risk many become manifest
during the extended survival resulting from administration of the
drug.
