Dramatic response to temozolomide, irinotecan, and bevacizumab for recurrent medulloblastoma with widespread osseous metastases.

There is little evidence to guide the choice of chemotherapeutic agents for osseous metastases in medulloblastoma. Recently, triple therapy with temozolomide, irinotecan, and bevacizumab has been reported to have efficacy in recurrent medulloblastoma, and this regimen alone and in combination with other agents has been tested in several early-phase clinical trials. Here we report a 20-year-old woman with multiply-relapsed medulloblastoma with numerous osseous metastases 8 years after original diagnosis who responded dramatically to temozolomide, irinotecan, and bevacizumab therapy. This case highlights the potential for this regimen in treating osseous metastases in medulloblastoma.
