CPT-SIOP-2000 Treatment of tumors of the choroid plexus epithelium. An intercontinental phase III chemotherapy study for patients with choroid plexus tumors
Disease Tumors of the Plexus choroideus
Therapy / Study arms

After maximal possible resection, all patients with Choroid Plexus carcinoma (CPC), metastasized tumors and incompletely resected atypical plexus papilloma ree randomized to a treatment with either carboplatin or cyclophosphamide given together with etoposide and vincristine. After the first interim analysis at the committee meeting in Vancouver 2005, it was decided to stratify the randomization by age to keep an even number of radiated patients in each treatment group. A total of 6 courses of chemotherapy (VP16 100 mg/m2 d1-5, vincristine 1.5 mg/m2 d1 and either carboplatin 350 mg/m2 d1+2 or cyclophosphamide 1000 mg/m2 d1+2), and additional irradiation after the second course for those who are older than 3 years of age was given. Patients with metastasized atypical choroid plexus papilloma (APP) and CPC, and patients with non-metastasized CPC non-responsive to chemotherapy (Stable desease, Progressive desease) received craniospinal irradiation with 35 Gy and local boost up to a total of 54 Gy. Patients with choroid plexus papilloma and completely resected atypical papilloma were closely followed without further treatment.
