title: Phase II trial of etoposide in APUD tumors.
abstract: Thirty-three patients with advanced, metastatic APUD tumors (islet cell, carcinoid, or medullary carcinomas of the thyroid) were treated with etoposide as a single agent. Of 29 evaluable patients, four (14%) had partial responses (95% confidence limits, 1%-26%). Toxic effects seen were those previously reported for etoposide as a single agent. Etoposide has activity in APUD tumors; further studies with this agent are indicated.
