Efficacy of sequential chemotherapy including methotrexate and doxorubicin in an infant with partially resected choroid plexus carcinoma.

This report refers to a 3-month-old male, with a residual choroid plexus carcinoma following partial resection, who was successfully treated with sequential chemotherapy without any postoperative radiation therapy. Along with carboplatin, we also used doxorubicin and methotrexate, hypothesizing that, given the patient's age, the blood-brain barrier should not hamper drug delivery to the tumor. According to this hypothesis, the treatment achieved complete remission of the disease, which lasts 27 months after the diagnosis.
