Brain Tumours

Non - germinomatous GCT

Target volume / conclusions

Predominantly local failures

Conflicting data (Outcome / pattern of relapse)

High ventricular failure rates after chx. alone

sanctuary site for failures (like in germinoma) ?

Local and spinal failures independent of target volume (CSI versus local RT) metastatic disease : CSI necessary

Local RT sufficient in non-metast. disease ?
