Summary Etoposide (VP-16), 150 mg/M2, given intravenously daily for 3 days every 3 weeks resulted in 3 complete responses and 6 partial responses in 154 patients with a spectrum of recurrent malignant solid tumors. There was evidence of disease control in an additional 37 patients (27 mixed responses and 10 stable disease). These responses occurred primarily in patients with Ewing's sarcoma, Hodgkin's disease, neuroblastoma and rhabdomyosarcoma. Most of the patients had every extensive prior therapy; however prior therapy with teniposide (VM-26), the congener of VP-16, did not seem to preclude responses to the latter drug. Myelosuppression was the principal form of toxicity. Neutropenia characterized by absolute neutrophil counts of 0.5 to 0.9 × 109/L occurred in one-half of the patients, and thrombopenia with platelet counts of 〈 25 to 49 × 109/L in one-fourth. These results demonstrate a favorable therapeutic index for VP-16 in several recurrent childhood solid tumors, supporting its use as a component of primary therapy for these diseases.
