|Overall poor prognosis. Gain of 19q, amplification of EGFR, and homozygous loss of CDKN2A are seen primarily in patients over age 40. Co-gain of 19 and 20 may be associated with longer survival.

|Array findings characteristic of higher grade tumors when histology supports lower grade may suggest increased likelihood of recurrence. Polysomy, particularly involving chromosome 5, are seen in angiomatous meningiomas. LOH 1p and/or LOH 1p/14q correlated with anaplastic transformation.

|Loss of 9p and amplification or gain of 17q23 are more frequent than other abnormalities. Gain of 1q is assocociated with a shorter PFS; Loss of 1p, 9p and 10 appear with greater frequency as tumor grade increases.
