Cancer in Pregnancy: Pentostatin
Pentostatin (Deoxycoformycin; Covidarabine) is a potent non-competitive inhibitor of adenosine deaminase. Pentostatin is used in the treatment of lymphoproliferative malignancies, particularly hairy cell leukemia.
|Animal studies *||mouse||5 mg/kg||In mice the mode of action is via abnormal development of the allantois 1. Using 5 mg/kg on day 7, defects of neural tube closure and arch development were found on day 10 and followed by a high rate of embryonic loss 2|
|rabbit||up to 0.02 mg/kg daily.||In the rabbit fetal toxicity occurred after intravenous administration but no teratogenicity 3. Fuchigami et al (1991) gave up to 0.1 mg/kg intravenously and found fetal death and toxicity at 0.02 mg per kg but no teratogenicity. 4|
|rats||0.75 mg/kg||In rats fetal resorptions were increased and body weight reduced along with skeletal abnormalities and defects 3.|
|mice||up to 1 mg/kg||Deficiency in spleen and thymus weight has been noted after perinatal treatment of mice with deoxycoformycin 5. All pups from dams treated during the last 5 days of pregnancy with deoxycoformycin died within 2 days of birth; however, treatment during embryogenesis had no effect on pup survival.|
|Human studies||No epidemiological studies of congenital anomalies in infants born towomen treated with dacarbazine during pregnancy have been reported.|
