Table 1 Patient information

From: Over-representation of specific regions of chromosome 22 in cells from human glioma correlate with resistance to 1,3-bis(2-chloroethyl)-1-nitrosourea

Tumor codea Ageb Sex Diagnosisc Treatmentd Days between primary and secondary surgery Survival (days)
DI/DIR 38 F GBM Irradiation and BCNU 111 426
LX/LXR 48 M Gliosarc./GBMe Irradiation and BCNU 203 466
ME/MER 49 F GBM Irradiation and BCNU 138 285
  1. a The tumor code is a random 2 letter code. Recurrent tumor from the same patient receives the same code with the addition of R. For each patient the primary and recurrent tumors were diagnosed by the same neuropathologist.
  2. b Age in years at diagnosis of primary tumor.
  3. c GBM = glioblastoma multiforme; gliosarc. = gliosarcoma.
  4. d BCNU = 1,3-bis(2-chloroethyl)-1-nitrosourea.
  5. e Different diagnoses of primary and recurrent tumors. Gliosarcoma is considered a variant of glioblastoma multiforme and the gliomatous and sarcomatous areas have similar genetic profiles and are thought to have a monoclonal origin [22,23]. Tumor LX was primarily glial, with a small sarcomatous element.
