RATIONALE: Gathering information about how young patients with ependymoma respond to standard combination chemotherapy and learning about the long-term effects of this treatment may help doctors plan better treatment.
PURPOSE: This phase III trial is observing young patients with ependymoma undergoing standard combination chemotherapy.
- To determine the overall survival and event-free survival of all infants diagnosed with ependymoma before their third birthday.
- To determine the overall survival and event-free survival of infants diagnosed with ependymoma before their third birthday when treated with standard chemotherapy comprising vincristine, carboplatin, high-dose methotrexate, cyclophosphamide, and cisplatin.
- To investigate the reasons why the primary tumor was completely resected in patients who were able to undergo complete resection of the tumor.
- To continue to investigate the biological characteristics of ependymoma.
- To correlate functional imaging studies of ependymoma with biological characteristics of the tumor.
- To provide a standard treatment regimen for patients with residual disease after optimal surgery who have already participated in a phase II study.
- To prospectively document renal function, hearing, and neurocognitive late effects after completion of study treatment.
OUTLINE: This is a multicenter study. Patients are stratified according to extent of prior surgical resection and presence of metastatic disease (complete resection of tumor vs metastatic disease at diagnosis vs no complete resection of tumor).
Patients receive vincristine IV on days 1, 15, and 29, carboplatin IV over 1 hour on day 1, high-dose methotrexate* IV over 24 hours on day 15, cyclophosphamide IV over 1 hour on day 29, and cisplatin IV over 48 hours on days 43 and 44. Treatment repeats every 8 weeks for 7 courses in the absence of disease progression or unacceptable toxicity. Patients with residual disease after completion of treatment may receive other treatment at the discretion of the investigator.
NOTE: *Patients initially treated on clinical trial CCLG-CNS-2005-03 who have no residual disease do not receive high-dose methotrexate in courses 5-7.
Patients undergo observational assessments comprising physical and neurological examination; MRI/ MRS scanning of the head and spine; and audiology, renal, endocrine, neurocognitive, and quality of life evaluations periodically for at least 5 years after the completion of study treatment.

Compare the efficacy of adjuvant chemotherapy with Cisplatin or Carboplatin and Gemcitabine versus Gemcitabine in patients with resected or ablated intra-hepatic cholangiocarcinoma.
One course of adjuvant carboplatin AUC7 is considered internationally to be a standard treatment option in clinical stage I seminoma, regardless of risk factors. Treatment is based on a la...
This study is a multicenter, open-label, two-arm, randomized, parallel Phase 2 feasibility study of pemetrexed in combination with either cisplatin (Arm A) or carboplatin (Arm B) as adjuva...

Methotrexate is one of the most widely used disease-modifying anti-rheumatic drugs. The hepatotoxicity of methotrexate resulted in poor compliance with therapy. The current study was designed to analy...
Here we report a new study performed at single molecule level on the interaction of the antineoplastic drug Carboplatin and the DNA molecule - the main target of the drug inside cells in cancer chemot...

Weekly paclitaxel, carboplatin, cetuximab, and cetuximab, docetaxel, cisplatin, and fluorouracil, followed by local therapy in previously untreated, locally advanced head and neck squamous cell carcinoma.
The survival advantage of induction chemotherapy (IC) followed by locoregional treatment is controversial in locally advanced head and neck squamous cell carcinoma (LAHNSCC). We previously showed feas...
More than 50% of all patients with advanced urothelial carcinoma cannot receive highly toxic cisplatin-based chemotherapy as the first-line treatment because of their unsatisfactory performance status...
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.

Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
An enzyme that catalyzes the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. EC 220.127.116.11.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
