Acute pancreatitis is an uncommon but serious complication of cancer c
hemotherapy. A 16-year-old girl with metastatic osteosarcoma experienc
ed recurrent bouts of symptomatic pancreatitis 24 hours after treatmen
t with ifosfamide administered as a single agent. To the authors' know
ledge, this is the first report of an association between ifosfamide a
nd pancreatitis. Because serum amylase levels are not monitored routin
ely during treatment with most chemotherapeutic agents, subclinical ca
ses of pancreatitis with ifosfamide and other agents may go undetected
