A staging system for brain stem gliomas

This is the authors' abstract. We don't add key points for this paper.

Intrinsic brain stem neoplasms are almost invariably malignant, and irrespective of radiation treatment and chemotherapy, are associated with a very abbreviated survival. It is possible that occasional long-term survival is the result of a radiation-sensitive low-grade astrocytoma. It is suggested that a primary staging system may separate poor-risk and good-risk patient populations and that this classification may be important in assessing future therapeutic options.
