New chemotherapy regimen prolongs survival in difficult-to-treat childhood brainstem gliomas

Barcelona, Spain: Childhood brainstem gliomas (BSGs) are rare but can be very difficult to treat successfully and they tend to have poor survival rates. However, a team of Spanish researchers have found that a chemotherapy regimen of irinotecan and cisplatin (I/C) produced rapid clinical responses...
