Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

High risk/recurrent central nervous system (CNS) tumors have a poor prognosis so that tandem high dose chemotherapy (HDCT) with hematopoietic progenitor stem cell rescues has been chosen as potentially curative therapy. Many institutions have used carboplatin, thiotepa, etoposide (CTE) for conditioning regimen of 1st HDCT and cyclophosphamide, melphalan (CM) for conditioning regimen of 2nd HDCT. Our institution applied this regimen to the 38 pediatric patients with high risk brain tumor since 1996. Although the 3 year overall survival rate and event free survival rate were improved to 69% and 47.9%, respectively, the results showed relatively high treatment related mortality (TRM) rate of 21%. Toxicity of this tandem regimen was also reported as being high up to 32% in other researches as well so that this regimen is considered not feasible due to toxicity. In this study, the investigators plan to improve event free survival rate and reduce treatment related toxicities of pediatric patients with high risk/recurrent CNS tumors by administrating tandem high dose chemotherapy and autologous stem cell rescue with topotecan, thiotepa, carboplatin (TTC) for 1st HDCT and melphalan, etoposide, carboplatin (MEC) for 2nd HDCT.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
