Notes
**Note 1**: According to AJCC, p. 594: "Tumors affecting the central nervous system rarely develop extraneural metastases, probably because of inherent biologic characteristics of these tumors, and also because the brain does not have a well-developed drainage system. . . . Certain tumors do spread through cerebrospinal fluid (CSF) pathways, and such spread has a major impact on survival."Default
