Table 2 Summary of clinical data of patients with ODG and OAC, and immunohistochemistry of their tumors.

From: Id4 and FABP7 are preferentially expressed in cells with astrocytic features in oligodendrogliomas and oligoastrocytomas

  1. 1 ODG III, oligodendroglioma, grade III.
  2. 2 OAC III, oligoastrocytoma, grade III.
  3. 3 OAC II, oligoastrocytoma, grade II.
  4. 4 Alive or dead of the patients was determined by the date of the most recent follow-up (9/30/04).
  5. 5 The date of diagnosis to 9/30/04 was defined as the survival time for patients who were alive.
  6. 6 Positive in microgemistocytes (MG).
  7. 7 This was a frozen section with 50% of tumor cells positive for GFAP, but H & E did not show microgemistocytes; the result was therefore questionable.
  8. 8 This was a frozen section with lots of freezing artifect; the result was not interpretable.
  9. 9 A small group (<5%) of tumor nuclei were positive.
  10. 10 Both cytoplasm and nuclei were positive.
  11. * Specimens that have been analyzed by cDNA microarrays.
