简要总结
RATIONALE: Drugs used in chemotherapy, such as pemetrexed disodium, use different ways to stop tumor cells from dividing so they stop growing or die. Pemetrexed disodium may stop the growth of tumor cells by blocking the enzymes necessary for their growth.
PURPOSE: This phase I trial is studying the side effects and best dose of pemetrexed disodium in treating young patients with recurrent solid tumors.
详细描述
OBJECTIVES:
Primary
- Determine the maximum tolerated dose of pemetrexed disodium in children and adolescents with refractory solid tumors.
- Determine the dose-limiting toxic effects of this drug in these patients.
- Determine the pharmacokinetics of this drug in these patients.
Secondary
- Determine, preliminarily, the antitumor activity of this drug in these patients.
- Correlate the presence of the C677T polymorphism of the methylenetetrahydrolate reductase gene, the presence of a polymorphism in the enhancer region of the thymidylate synthase (TS) gene promoter (2R and 3R tandem repeats), the presence of a polymorphism within one of those repeats, and the presence of a functional polymorphism in the 3'-untranslated region with toxicity in patients treated with this drug.
- Correlate homocysteine and methylmalonic acid levels at study entry with toxicity in patients treated with this drug.
- Correlate various gene expression profiles with response in patients treated with this drug.
