RESUMO
A 26-year-old pregnant woman with a fast-growing malignant deep-seated brain glioma was offered a therapeutic abortion to allow subsequent surgical resection. This option was refused by the mother, but the fast tumor growth placed the life of both mother and child at risk. A staged CyberKnife radiosurgery treatment was then planned, aiming to provide at least temporary tumor growth control and allow a safe delivery while keeping the doses received by the fetus well below the allowed doses. Growth control and the safe delivery of a healthy child were achieved after this first treatment. An intensive chemotherapy program based on the combination of Avastin, irinotecan, and Temodal was then started. Recurring tumor growth was treated with a second CyberKnife procedure while continuing the above chemotherapy protocol. At 43 months after the second CyberKnife procedure, the tumor had disappeared on magnetic resonance imaging. Neither mother nor child showed the neurological sequelae. Staged radiosurgery and deferred chemotherapy proved to be a safe and effective treatment to allow the delivery of a healthy child and the long-term control of an aggressive brain glioma.
