Brief Summary
The purposes of this study include:
- Determination of the change in clearance of topotecan and topotecan lactone between day 1 and day 14 for patients receiving treatment with p.o. topotecan and p.o. cyclophosphamide x 14 days.
- Determination of the correlation between the activity of CYP3A4, as measured by the 14C- Erythromycin Breath Test (ERMBT), and topotecan/topotecan lactone clearance for patients receiving treatment with p.o. topotecan and p.o. cyclophosphamide x 14 days.
- Determination of the response rate to oral cyclophosphamide and oral topotecan in recurrent and/or refractory pediatric solid tumors.
- Obtain additional safety data for the chemotherapy regimen, p.o. topotecan and p.o. cyclophosphamide x 14 days.
- Report the frequency of severe toxicities associated with the level of CYP3A4 activity, as measured by the ERMBT, for patients receiving treatment with p.o. topotecan and p.o. cyclophosphamide x 14 days.

Eligibility Criteria
You may qualify if:
- Patients must be less than 22 years of age inclusive
- Tumor histologies: medulloblastoma/PNET, neuroblastoma, sarcomas, and other pediatric solid tumors for which there is no known effective therapy.
- Patients must have measurable disease, documented by clinical, radiographic, or histologic criteria.
- Patients must have a performance status of 0, 1 or 2. Use Karnofsky for patients \> 16 years of age and Lansky for patients \<= 16 years of age.
- Patients must have a life expectancy of \>= 8 weeks.
- Prior Therapy: Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.
- Patients must not be taking the following medications: growth factors, steroids, and CYP3A4 inducers or inhibitors.
- Patients must have adequate bone marrow, renal, liver function, pulmonary, or central nervous system function.
- Must be able and willing to participate in all study procedures, including the ERMBT and pharmacokinetic studies.
- All patients and/or their parents or legal guardians must sign a written informed consent. (11) All institutional, FDA, and NCI requirements for human studies must be met.
You may not qualify if:
- Males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method.
- Patients with an uncontrolled infection.
- Allergy to erythromycin
- Patients who have previously received either cyclophosphamide or topotecan are eligible for this study.
