A phase II trial of piroxantrone in adenocarcinoma of the pancreas. A Southwest Oncology Group study.

Thirty-five evaluable patients with advanced adenocarcinoma of the pancreas were treated with piroxantrone at a dose of 150 mg/m2 intravenously every 21 days. No objective responses were observed (95% confidence interval 0%-10%). Toxicities of grade > or = 3 were primarily hematologic and were seen in 28 patients. Piroxantrone is inactive in pancreatic cancer and no further investigation of this agent in this tumor is recommended.
