[A case report of choroid plexus carcinoma]

Choroid plexus carcinoma (CPC) is a rare tumor with poor prognosis, whose optimal treatment has not yet been established. We report a case of a one-year-old infant who has been treated with successive combined therapy. The therapy involved two operations for partial removal, interrupted radiotherapy up to 12Gy, 2 cycles of salvage chemotherapy, followed by an operation for total removal, and then a further 3 cycles of chemotherapy. CT scan after the preoperative salvage chemotherapy showed remarkable shrinkage of the residual tumor, which made operative procedure easier. The patient was disease-free for ten months after the last operation. Patients with combined preoperative chemotherapy and total resection seem to enjoy prolonged progression-free survival, so preoperative chemotherapy for choroid plexus carcinoma seems to be of benefit, despite the fact that its optimal recipe has not yet been established.
