Antitumour activity of cytotoxic agents, evaluated in patients with AIDS-related Kaposi's sarcoma (KS), is about 30-80%. However, responses are mostly partial and short. Experience with etoposide is similar. Teniposide has a longer elimination half-life and superior antitumour activity compared with
We analyzed multidrug-resistance gene (mdr1 gene) expression in a patient with undifferentiated sarcoma of the liver using the cloned cDNA for the mdr1 gene. Tissue samples were available at the time of initial diagnosis and of two intracranial relapses after chemotherapy with a regimen including
OBJECTIVE

METHODS
One hundred two infants (< or = 12 months old) were included. Twenty-four
BACKGROUND
Patients with metastatic, progressive or recurrent Ewing sarcoma have a poor prognosis. In addition to increasing the intensity of conventional chemotherapy, the combination of irinotecan and temozolomide has been proposed as an effective salvage regimen for some pediatric
OBJECTIVE
In this phase II and pharmacokinetic study, chronic, low-dose, oral etoposide was evaluated for its efficacy in patients with AIDS-related Kaposi's sarcoma who were not previously exposed to cytotoxic therapy.
METHODS
Of 28 patients accrued for the study, 25 were assessable for toxicity
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
