Diagnostic and Prognostic Markers in Low-Grade Gliomas


OBJECTIVES:

- Evaluate the diagnostic and prognostic relevance of alterations of specific chromosomes
and chromosomal regions including 7, 9p, 10p, 10q, 13q, 17p, 17q, 19q, 22q, X, and Y,
using PCR analysis of microsatellite repeats and FISH.

- Evaluate the diagnostic and prognostic relevance of DNA ploidy by flow cytometric
analysis; compare with ploidy determination by FISH.

- Assess the diagnostic and prognostic relevance of various markers of cellular
proliferation and cellular function including flow cytometric determination of
%S-phase, %G2M, and immunohistochemical evaluation of PCNA, Ki-67, and p53.

OUTLINE: Previously preserved paraffin-embedded tissue blocks are obtained and used for
biomarker studies. Blood samples obtained during treatment are also obtained. Loss of
heterozygosity of specific chromosomal regions are performed using PCR analysis of
microsatellite repeats (41,118-120) on DNA extracted from the paraffin-embedded archival
specimens. FISH and flow cytometry may also be used to assess chromosomal loss of deletion.
Immunohistochemistry is also performed.
